摘要： A mold for shaping a skin sheet has a three-dimensional body including a top surface and side surfaces that work as a shaping surface, respectively. The top surface and the side surfaces have a plurality of small holes communicating with a suction unit for drawing the skin sheet thereon by suction force generated by the suction unit. Each of the side surfaces has a product portion and a non-product portion parted at a trimming line, the portions corresponding to those of the skin sheet that are used as a product and not used as the product, respectively. The body has a plurality of guidance plates, each projecting outside at an edge line of the body. An upper edge of each of the guidance plates forms a ridge line in a shape of a wave. The ridge line descends from a position in the vicinity of an intersection point of the edge line and the trimming line to a direction of the bottom of the body so as to form a valley and thereafter ascends to an opposite direction so as to form a mountain. The height of the deepest point of the valley is lower than that of the trimming line.

摘要： A method for making plastic tooling by forming a surface coat over a model of the article to be made. While still in a tacky condition, the surface coat is sprinkled with sand. After the surface coat is cured and has adhered to the sprinkled sand, the surface coat is wet with a laminating resin. Then a sand and epoxy mixture is poured into the core box to form the tool. Another version of the method includes the steps of disposing a vacuum tube into the sand-epoxy core and closing off the open side of the core box through which the core mix was tamped. The surface coat is applied around the model so that the cavity in the finished core is suitable for vacuum-forming an object without forming the conventional vacuum holes.
摘要翻译：一种通过在要制造的制品的模型上形成表面涂层来制造塑料加工的方法。在仍然处于粘性状态下，表面涂层上撒上沙子。在表面涂层固化并粘附到喷砂之后，表面涂层用层压树脂湿润。然后将砂和环氧树脂混合物倒入芯盒中以形成工具。该方法的另一种方法包括以下步骤：将真空管设置在砂环氧树脂芯中，并封闭芯盒的开放侧，芯组合被夯实。表面涂层施加在模型周围，使得成品芯体中的空腔适合于真空成形物体而不形成传统的真空孔。

摘要： A process for producing plastic parts, in particular molded plastic articles that are deep-drawn in a shaping contrivance into molded articles from at least one heated plastic foil, with the molded articles then being separated from the molded article assemblage in the separating contrivance and conveyed with the aid of a transport contrivance to successive processing stations such as a printing unit, or a stacking contrivance or the like. The shaping and detaching of the individual molded articles made of the still warm foil are executed directly after one another at one station, with forming taking place first and detaching then following by means of strip steel cutting, while the form still remains in the closed condition. It is also possible, with the aid of this process, to produce molded articles consisting of two superimposed foils with layers of an absorbent material disposed therebetween.

摘要： A readily adjustable mold is provided for transforming a heated plastic sheet into an adapter intended to restrain a received article from moving inside a container larger than the article. The adapter to be formed has a base configured to fit snugly within the container and a plurality of projections on the base that are spaced from each other to receive the article snugly therebetween. The mold comprises means including side and bottom walls that define a cavity with peripheral and medial regions, for operatively positioning the plastic sheet for formation of the adapter, and means disposed in the cavity peripheral region and moveable toward and away from the cavity medial region, for selectively locating the projections on the adapter base. The locating means in the peripheral region may include one or more projection-forming member(s) slideably mounted on each of at least two of the side walls for selective movement toward and away from the medial region. Any such member(s) may be independently moveable for such selective movement individually. The peripheral region may further include a removably insertable member adjacent to at least one of the side walls, to reduce at least one outside dimension of the adapted. Inwardly adjacent to that member, another such member may be disposed to further reduce said dimension(s), and may have one or more projection-forming member(s) extending therefrom toward the medial region to help center the received article in its container.

摘要： An improved method and apparatus for rapidly forming plastic foam shells from a flexible foam sheet. The foam sheet is intermittently passed through a radiant heating unit and is rapidly heated on both sides to 130.degree.-250.degree. F. to soften the foam. The heated foam sheet is immediately passed through a forming die unit in which the foam sheet is deformed partly into the die cavity by withdrawal of air from the cavity, and a die plug descends and final forms a shell while rapidly cooling the foam shell to below its plastic deformation temperature. By this forming method and apparatus, ethylene-containing foam shells having a depth 10-25 times the foam sheet initial thickness are rapidly formed at 10-30 cycles/minute.

摘要： An improved vacuum forming process for forming a deep drawn plastic article with a flange in an area of high forming stresses wherein a mold mounted on a base forms the shape of the article. A sheet of hot plastic material is placed over the mold and a vacuum is drawn to form the plastic sheet into the shape of the mold to form the article. The improvement is forming a character in the mold portion that forms the flange in the area of the high forming stress, said character having dimensions such that properly heated plastic sheet material will be imprinted with a predetermined clarity during the molding operation. A heated sheet of plastic material is placed over the mold and a vacuum is drawn to draw the plastic material around the mold including the mold portion that forms the flange in an area of high forming stresses. The plastic material is then solidified and removed from the mold. The flange is visually inspected to determine if the imprinted character has the predetermined clarity. If it does, the plastic material was heated to the proper temperature for the molding operation. If it does not, it means that the plastic material was not heated to the proper temperature and the area will be subjected to stress cracking and therefore the article is defective and should be discarded.
摘要翻译：一种改进的真空成型方法，用于在高成形应力的区域中形成具有凸缘的深拉塑料制品，其中安装在基座上的模具形成制品的形状。将一片热塑性材料放置在模具上并抽出真空以将塑料片形成为模具的形状以形成制品。改进之处在于在成形应力高的区域形成凸缘的模具部分中的特征，其特征在于，在成型操作期间具有适当加热的塑料片材以预定的透明度被印刷的尺寸。将加热的塑料材料片放置在模具上并且抽出真空以将塑料材料围绕模具拉出，包括在高成形应力的区域中形成凸缘的模具部分。然后将塑料材料固化并从模具中取出。目视检查凸缘，以确定压印字符是否具有预定的清晰度。如果是这样，将塑料材料加热到合适的温度进行模制操作。如果没有，则意味着塑料材料没有被加热到适当的温度，并且该区域将受到应力开裂，因此制品有缺陷并应被丢弃。

摘要： In the air-pressure molding method according to the present invention, a laminated material is arranged, when in a heated and softened state, on the shaping face of a mold having an air reservoir, and the portion to be molded is hermetically sealed within a box-shaped top cover. Air under pressure higher than atmospheric pressure is then applied to the inside of the top cover so that the laminated material is developed and shaped to have a uniform thickness on the air-cushion layer which is established by the air pressure between the laminated material and the shaping face of the mold. Immediately after, the air in the cushion layer is forced to the air reservoir thereby bringing the laminated material into contact with the mold so that the surface of the skin may be reversely embossed or stitched.

摘要： An apparatus for the production of plastic pipes with transverse grooves comprising half shells each having a mold recess which are arranged on a machine bed driven in a cycle. The half shells are assembled in pairs in a molding path to form a complete mold, the injection head of an extruder being arranged at the beginning of the molding path. Furthermore, the half shells are provided with vacuum channels, each vacuum channel being connected to a respective mold recess. The vacuum channels are joined into vacuum connections formed in the machine bed, and the half shells are provided with cooling channels which join into cooling water inlets and outlets in the machine bed. In order to ensure an exact setting of the half shells during the molding operation, the cooling channels, on the one hand, and the vacuum channels on the other hand, in a given half shell are completely separated from each other.
