Problems solved by technology

It simplifies the structure of the clamping plate, especially the high-speed and high-efficiency injection molding can be completed by only one continuous action of the cylinder, but it finally forms three movable plates and one fixed plate; during the injection molding process, the clamping cylinder and The injection machines are all moving, and the mechanism becomes complicated and prone to failure; the integrated oil cylinder has a long moving distance, and the oil circuit requires a large amount of oil, so there is still a need for improvement

Embodiment Construction

[0033] refer to figure 1 and 2 , there are only two templates of the double-platen rapid injection molding machine, and the structure is simplified. One of the installation methods of the templates and related devices and mechanisms is to fix the fixed template 4 and the injection device on the frame, and the injection port of the injection device is placed in the center of the fixed template 4. , the lower end of the moving template 5 and the frame have a sliding support structure so that the moving template 5 can move horizontally smoothly. The sliding supporting structure, frame and injection device are well known to those skilled in the art and are not shown. Clamping oil cylinder 2 and clamping oil cylinder 1 can be installed on one template or respectively on two templates. In this embodiment, they are respectively fixed on both sides of fixed template 4 and connected with low pressure and high pressure oil circuits respectively. The piston rod 111 of the mold clamping ...

Abstract

The double-formwork quick injection molding machine includes frame, injection molding unit, oil path, control mechanism, mold closing cylinder, mold locking cylinder, pushing-out mechanism, moving formwork and fixed formwork. There are oil hole in the mold locking piston in the mold locking cylinder and corresponding blocking pin in the back end cap of the mold locking cylinder for blocking the oil hole during mold locking operation. The present invention is stable, smooth, reliable, small and saving in power.

Description

technical field [0001] The invention relates to a double-platen rapid injection molding machine. Background technique [0002] The existing injection molding machine process generally uses a three-plate type, clamps the mold with a mold clamping cylinder, locks it with a mold clamping cylinder, and then injects. Its body is very long and occupies a large area, so it is rarely used now. In order to simplify equipment and improve work efficiency, two-platen injection molding machines have come out. Chinese patent CN2065543 "Double-Motion Injection Molding Machine" introduces a platen 1 fixed on a tie rod that can move toward platen 2, and platen 2 moves toward the nozzle; The integrated oil cylinder is fixedly installed on the transmission seat and can slide along the injection seat; the clamping oil cylinder is fixed on the right side of the template 2, and the piston rod at the right end can slide on the injection seat, an injection molding machine consisting of only two tem...
