Abstract

A die opening and closing device for a movable die plate 2 and a fixed die plate 1 includes a toggle link 5 disposed between the movable die plate 2 and a die tightening housing 8, a cross head 6 for flexing the toggle link 5, and a motor-driven ball screw 7 penetrating through the die tightening housing 8 and inserted into the cross head 6, and this die opening and closing device is provided with die thickness adjusting means 9 for adjusting the die thickness S when the die is tightened by extension of the toggle link 5, and ball screw rotation control means 20 for controlling constant the cracking gap, and a foamed resin molding machine is presented, together with its operating method.

Description

technical field [0001] The present invention relates to a foamed resin molding machine for manufacturing foamed molded products and an operating method thereof. Background technique [0002] The foamed resin molding machine generally used in the fields of foaming and molding is designed as a structure consisting of a fixed platen and a movable platen, as disclosed in, for example, Patent Document 1, which is used to operate by driving a piston Approach or separate from each other to open and close templates. Specifically, the structure uses the Figure 5 The mold opening and clamping device shown, wherein the piston 511 is installed on the movable platen 2 with the movable mold 4 attached to its front, and the piston 511 is driven by the driving cylinder, and the movement of the movable mold 4 makes it move closer or farther away Fixed mold 3 attached to fixed template 1. [0003] In such a foamed resin molding machine, corresponding to foamed and molded products, si...
