摘要： An improved injection molding apparatus having a fixed mold 7 having a molten resin passage 16b and a movable second mold 8 having a molten resin passage 18 is presented in which residual hardened resin left in molten resin passages of the injection apparatus is removed automatically after every injection operation. The invented device is provided with a reciprocating member 34 which is coupled in molten resin passages 16b, 18, and during the injection step, the molten resin passage 16b is extended to the molten resin passage 18 by moving the reciprocating member 34 into the second mold to communicate a mold cavity 17 with a resin injection device 14. After the completion of the injection step, the reciprocating member 34 is moved to the back position to remove any resin left in the molten resin passage towards the first mold. The mold is then opened to separate the fixed mold 7 from the movable mold 8, leaving the reciprocating member 34 in the first mold so as to close off the opening of the molten resin passage 18. When the molds 16b, 18 are separated, this arrangement is effective in preventing exposing the passages 16b, 18 to ambient atmosphere, leading to leaking of molten resin from the passage 16b as well as preventing inclusion of air in molded products to cause a phenomenon called burning.

摘要： A resin molding method comprising a cleaning step comprising injecting a molten resin from a resin injection unit under such a condition that the matching portions of dies can be somewhat spaced from each other by loosening clamping of the dies to thereby permit the molten resin to flow into a cavity and a gap between the matching portions of the dies, and discharging a molding integrally formed by the cavity and the gap between the matching portions of the dies after the molten resin has solidified. Thus an attachment attached to the gap between the matching portions of the dies is mixed into moldings formed in the cleaning process, so that the attachment is discharged together with the moldings upon ejection of the moldings. Accordingly, cleaning can be positively and efficiently effected without expenses and without lowering an efficiency of the molding operation.
摘要翻译：一种树脂成型方法，包括清洁步骤，包括在树脂注射单元中注入熔融树脂，使得模具的匹配部分可以通过松开模具的夹紧而彼此稍微间隔开，从而允许熔融树脂流入模具的匹配部分之间的空腔和间隙，并且在熔融树脂固化之后，排出由空腔和模具的匹配部分之间的间隙一体形成的模制件。因此，附接到模具的匹配部分之间的间隙的附件被混合到在清洁过程中形成的模制品中，使得在模制品的排出时附件与模制品一起排出。因此，无需费用而且不降低成型操作的效率就可以有效地进行清洁。

摘要： An object of the present invention is to operate an ejector for performing gate cutting and ejection of a molded piece in an injection molding machine at an optimal speed according to a molding purpose. In the present invention, a means for setting an operation speed in gate cutting and a means for setting an operation speed in ejecting a molded piece are provided in a control device for a hydraulic or electric driving means for operating an ejector pin. In accordance with a structure like this, an ejector device is operated during gate cutting by the means for setting an operation speed of the ejector device in gate cutting, and during the subsequent ejection of a molded piece, the ejector device is operated by the means for setting an operation speed for the ejector device in ejecting a molded piece, which is different from that used in gate cutting, whereby a molded piece is ejected from a mold. In addition, when the operation speed of the ejector device in gate cutting becomes relatively high, there is generated no trace of the gate in a molded piece, and when the operating speed of the ejector device in ejecting a molded piece becomes low, there is generated no crack in a molded piece when ejected.

摘要： The present intention intends to operate an ejector which carries out gate cut and product ejection in an injection molding machine, at optimal speeds, respectively. According to the present invention, a control unit for controlling hydraulic or electric drive means for operating one or more than one ejector pin comprises operation speed setting means for gate cut and another operation speed setting means for product ejection. Such a structure enables to carry out gate cut by operating an ejector unit controlled by an ejector unit operation speed setting means for a gate cut and, subsequently, to carry out a product ejection from metallic molds by operating the ejector unit controlled by another ejector unit operation speed setting means for product ejection. The ejector unit is set at a comparatively high operation speed for gate cut so that no gate trace will remain, and at a comparatively low operation speed for product ejection so that no cracks will be generated in the product.
