摘要： The plastic molded article is produced by heating a mold by contact with a preheated salt bath. The salt bath is readily maintained at a uniform temperature and is self-insulating for energy efficiency. A noncontact infrared sensor monitors the mold cavity temperature while in the salt bath, and the mold is removed from the bath when the proper mold temperature is reached. A charge of plastic powder is introduced into the mold by clamping the mold to a powder slush box with the mold cavity confronting the opening of the box. The mold and box are then simultaneously rotated to pour the plastic charge into the mold. The plastic charge forms a skin on the cavity surface and additional plastic material may be built up to provide additional thickness. The mold and box are then separated; the mold is then postcured and cooled, whereupon the finished article may be removed from the mold.

摘要： Apparatus for reducing the waste neck area in a mold of vinyl cast articles such as automotive arm rests, head rests and parts of similar construction includes a powder box of gellable material having a supply spout with its exposed outer surface area covered by a liner of heat insulating material; a waste inlet neck on a heated, machined nickel mold is sealed by the liner when the powder box is joined to the mold. The powder box spout is at room temperature and shields the inlet neck to prevent gel build-up on the inlet neck to effect considerable cost by both a reduction in waste deposits of gel and a reduction in labor required to trim a waste area on the mold. To obtain the coating, the mold is coated with powdered vinyl (hereinafter gellable material) by casting from the powder box to the mold and the excess material is removed from the mold by dumping it from the mold into the powder box.

摘要： Apparatus and a process for manufacturing multiple color thin walled hollow shells for parts such as automobile door panels, controls and instrument panels from thermoplastic plastisol includes a plastisol box divider to form two or more compartments in a plastisol charge box and means for joining the charge box divider end-to-end with a mold separation edge on an open-ended heated mold for separating the mold into two or more sections; each compartment of the charge box has a different color plastisol. The charge box and mold are joined and then are rotated so that the plastisol is distributed into each mold section by gravity flow with the plastisol from each section flowing to the divider which separates the colors so as to form two or more tones on a resultant shell of cured material.

摘要： A method and apparatus for making doll clothing and doll house accessories includes a plurality of mold shapes or forms which are used to produce various articles of attire such as dresses, pants, and doll house furnishings such as cushions, curtains, rugs, flowers and many other items. Each of the garment molds may include detachable portions, such as the arms, to facilitate removing a finished article from the mold itself. The doll house accessories are made in generally flat molds which provide the texture and shape of the finished item. A viscous, liquid plastic is applied to the exterior surface of the mold by a brush or other tool to cover the exterior of the mold which defines the particular article. The liquid coating sets or solidifies to form a flexible article adapting the contours of the mold. The garment is then removed from the exterior of the mold.

摘要： A process for slush molding hollow thin-walled flexible plastisol articles which begins with the application of an initial thin coating of liquid plastisol to the interior surface of a cooled open mold. This initial coating is then gelled by impinging pressurized hot gas directly onto the exterior surface of the mold, preferably while the mold is inverted and rocking about a horizontal axis. Thereafter, the thickness of this initially gelled coating is increased by applying additional liquid plastisol to the interior surface of the mold, which additional plastisol is then gelled by the latent heat stored in the mold wall during the previous heating step. The entire gelled plastisol coating is finally fused by a second impingement of pressurized hot gas directly onto both the exterior mold surface and the plastisol coating on the interior mold surface, while the mold is rotating about a horizontal axis.
摘要翻译：一种用于搪瓷中空薄壁柔性增塑溶胶制品的方法，其开始于将液体增塑剂的初始薄涂层施加到冷却的开模的内表面。然后通过将加压的热气体直接冲击到模具的外表面上，优选地当模具反转并围绕水平轴线摇摆时，将该初始涂层凝胶化。此后，通过向模具的内表面施加附加的液体增塑溶胶来增加该初始凝胶涂层的厚度，然后在先前的加热步骤期间，另外的增塑溶胶被存储在模具壁中的潜热凝胶化。当模具围绕水平轴线旋转时，整个胶凝的增塑溶胶涂层最终通过第二次加压热气体的冲击而直接熔化在外部模具表面和内部模具表面上的增塑溶胶涂层上。

摘要： THIS INVENTION RELATES TO A METHOD OF HEATING MOLDS FOR USE IN MOLDING THERMOPLASTIC MATERIAL WHEREBY THE HEATING AND COOLING CYCLES OF THE MOLD ARE SUCH THAT THE SMALL MICROSCOPIC CRACKS OR HOLES IN THE ELECTROFORM MOLDS DO NOT LEAK OIL INTO THE MOLDING CAVITY TO THEREBY MAR, DISCOLOR AND RUIN THE MOLDED ARTICLE. MORE SPECIFICALLY, THIS METHOD OF MOLDING FEEDS THE HEATING MEDIUM OR OIL TO THE MOLD AT A PRESSURE OF AT LEAST ATMOSPHERIC OR HIGHER AND REMOVES THE OIL FROM THE OTHER SIDE OF THE MOLD AT A PRESSURE LESS THAN ATMOSPHERIC TO OBTAIN THROUGHOUT THE MOLD ON THE HEATING MEDIUM SIDE A PRESSURE LESS THAN ATMOSPHERIC.
