Pressurizing locking die and slideway type die opening and closing device for two-template injection molding machine

Abstract

The invention relates to a pressurizing locking die and slideway type die opening and closing device for two-template injection molding machine, which comprises a stander, wherein the stander is provided with an injection device, a die opening and closing device, a locking die device and an ejection device, wherein the die opening and closing device comprises a fixed template and a movable template, each template is provided with a mounting die, a die opening and closing oil cylinder is symmetrically arranged on one of the two templates according to the template center, and a die opening and closing oil cylinder piston rod is connected with the other one of the two templates. The pressurizing locking die and slideway type die opening and closing device for two-template injection molding machine is characterized in that the bottom of the movable template is provided with a slide block, the stander is provided with a slideway, the slide block is matched with the slideway, the locking diedevice comprises a pressurizing plate arranged in the template, and the pressurizing plate is provided with a pressurizing oil cylinder.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to a pressurized mold clamping and slide rail type mold opening and closing device for a two-platen injection molding machine, and belongs to the field of plastic machinery. Background technique [0002] Existing injection molding machines generally use the three-plate type, use the mold clamping cylinder chain rod type mold clamping method, and then inject molding. Its body is very long, occupies a large area, and the chain rod pins wear a lot. Each pin wears differently and causes locks. The mold is unbalanced, and the product has burrs. In order to simplify equipment and improve work efficiency, the applicant once applied for a "double-platen rapid injection molding machine", Chinese patent number ZL02244379.7, the main structure is: an injection device installed on the frame, an oil circuit, a control mechanism, and Opening and closing cylinder, clamping cylinder, item ejection m...

AI Technical Summary

Problems solved by technology

But its disadvantages are: since the movable template needs to be kept in balance when opening and closing the mold, the four piston rods need to work on the movable template at the same time. If one piston rod works slightly slower, the other three The mold opening and closing piston rod is fast, and the movable template will be stuck on the guide rod at an inclination angle; on the other hand, its mold clamping device limits the number of mold clamping cylinders. If it is to produce large workpieces, a more powerful cylinder is required. Clamping the mold consumes a lot of energy, and the oil cylinder is also modified, which increases the production cost
