Problems solved by technology

However, if the position sensor is installed on the mold, the cost will increase, and the connection and installation of the sensor will be required, which will lengthen the preparation time (Japanese: dantakeritime) before the start of molding.
In addition, since the position sensor needs to be attached to the mold, when the mold is operated at high temperature, etc., the position sensor is affected by the temperature and the reliability is reduced.

Abstract

Provided are an injection molding method and an injection molding device. Mould positions in micro mold-open states can be correspondingly changed with the change of mould positions in mold-closing states under predetermined pressure. Accordingly, even in the case that the mould positions in mold-closing states are changed caused by the change of temperatures, the mold-open amount in the micro mold-open states can be fixed and the moldings with stable quality can be formed by injection moulding in the micro mold-open states.

Description

technical field [0001] The present invention relates to an injection molding method and an injection molding device for injecting molding materials such as resin, glass, metal, etc. into a mold, and opening the mold by a predetermined amount before and after injection molding. Specifically, the present invention is applicable to the injection molding method of injecting molding materials such as resin, glass, metal, etc. in a state where the mold has been opened by a predetermined amount, and closing the mold after injection molding to apply a compressive force to the molding materials, or is suitable for applying Injection molding is an injection molding method in which molding materials are injected into a mold, and the mold is opened by a predetermined amount after injection to perform foam molding. In particular, the present invention relates to control for forming a molded product with less deformation or forming without a weld, and relates to a technology capable of stab...
