Embodiment Construction

[0046] Hereinafter, modes for implementing the present invention will be described with reference to the drawings, and the same or corresponding components will be given the same or corresponding reference numerals in each of the drawings, and description will be omitted. In addition, the moving direction of the movable platen at the time of mold closing is set to the front, and the moving direction of the movable platen at the time of mold opening is set to the rear.

[0047] figure 1 It is a figure which shows the state at the completion of mold closing of the injection molding machine which concerns on one Embodiment of this invention. Such as figure 1 As shown, the injection molding machine 10 includes a frame 11 , a fixed platen 12 fixed to the frame 11 , and a rear platen 15 arranged at a distance from the fixed platen 12 . The fixed platen 12 and the rear platen 15 are connected by a plurality of (for example, four) connecting rods 16 . The axial direction of the lin...

Abstract

An injection molding machine includes an ejector unit configured to eject a molding product from a mold and a mold release force sensor configured to detect a force to release the molding product from the mold.

Description

technical field [0001] The invention relates to an injection molding machine. Background technique [0002] Injection molding machines manufacture molded products by filling molten resin into the cavity space of a mold unit and solidifying it. The mold device is composed of a fixed mold and a movable mold, and a cavity space is formed between the fixed mold and the movable mold when the molds are closed. The molded product molded in the cavity space is ejected from the movable mold after the mold is opened. For this ejection, an ejector is used (for example, refer to Patent Document 1). [0003] Patent Document 1: International Publication No. 2005 / 068155 [0004] Conventionally, it was not possible to know the status of demolding. Contents of the invention [0005] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an injection molding machine capable of knowing the status of mold release. ...
