摘要： In an injection press molding machine of the present invention, a horizontal injection device (10) is disposed below a fixed die plate (2) of a vertical press device (1), the injection nozzle (10b) of its injection portion (10a) is bent in an L-shape and a valve (10c) for opening and closing a resin passage is disposed in this nozzle. A base (14) of a bed (4) supporting the horizontal injection device (10) slides with the injection nozzle (10b) as the center in accordance with thermal expansion and contraction of the horizontal injection device (10) and the L-shaped injection nozzle (10b) comes into contact with a lower mold (3) at a predetermined surface pressure. Therefore, color changeability of the resin and its purgeability are excellent and since a hot runner is not necessary, an economical and versatile mold can be obtained. Moreover, since the resin is packed using a short resin passage, molded articles having stable quality can be obtained. Even when the horizontal injection device (10) undergoes expansion and contraction, the lower mold (3) is not moved and resin leakage does not occur, either. Since the injection portion (10a) can move outward from below the fixed die plate (2), replacement and inspection of the injection nozzle (10b), the screw, and the like, can be made easily.

摘要： This invention relates to an improvement in an injection compression molding machine and method which injects and supplies a molten resin into a cavity defined by molds and then conducts compression step of pressing. The present invention relates to an injection compression molding machine and method which has stable quality and high productivity while preventing recesses of molded articles and the drop of precision resulting from the escape of the resin at the time of compression and from the variance of the mold cavity gaps by taking these problems into consideration. To accomplish these objects, the present invention shuts off the gate at the compression step, makes again injection after the compression step and supplies the resin. A mechanical fixing mechanism supports the back of a movable mold lest any variance of the gap between the molds should occur by the pressure at the time of injection, and the resin can be injected and supplied while the gap between the molds is restricted. In this manner, molded articles having good appearance and high dimensional precision can be molded with high stable quality and with high productivity.
摘要翻译：本发明涉及一种注射压缩成型机和方法的改进，该注射压缩成型机和方法将熔融树脂注入并供应到由模具限定的空腔中，然后进行压制压缩步骤。本发明涉及一种注塑压缩成型机及其制造方法，其质量稳定且生产率高，同时防止模压制品的凹陷和由压缩时树脂逸出所引起的精度下降和模腔变化考虑到这些问题的差距。为了实现这些目的，本发明在压缩步骤中关闭浇口，在压缩步骤之后再次注入并供应树脂。机械固定机构支撑可移动模具的背部，以防止在注射时由于压力而发生模具之间的间隙的任何变化，并且可以在模具之间的间隙受到限制的同时注入和供应树脂。以这种方式，具有良好外观和高尺寸精度的模制品可以以高稳定质量和高生产率模制。
