Problems solved by technology

The fly in the ointment is: this equipment and method are only suitable for the manufacture of small-scale injection molding products of light weight, but then can't realize with the way of injection molding for large-scale products, for example: (1) such as building materials aspect has: all kinds of house walls, partition walls, Floors, pallets, beam tops and other parts cannot be realized by injection molding or injection molding splicing products; (2) In terms of transportation: boats, aircraft floors, car shells, train passenger compartments, and car trailers cannot be spliced ​​by injection molding or injection molding Product realization; mechanical aspects: various filter plates, various large-scale industrial products cannot be injection molded at one time

Embodiment 1

[0015] Embodiment 1: with reference to accompanying drawing 1. The equipment for precision injection molding of large-scale products, one or two or more large hydraulic presses is the existing equipment, and its workbench is used to control the clamping and opening of the hot runner injection mold. The processing and production of the hot runner injection mold are modern There are technologies, which will not be described here. One or two or more injection molding units are fixed or mobile. The discharge port of one or two or more storage constant temperature injection molding cylinders is connected with the feed inlet of the hot runner injection mold. The storage constant temperature injection molding cylinder is composed of cylinder body, piston, material inlet, discharge port and check valve. Composition, the cylinder body is a thermal insulation cylinder body, the piston is an oil cylinder piston and is controlled by the oil cylinder and an automatic control device, and t...

Embodiment 2

[0017] Embodiment 2: On the basis of Embodiment 1, a plastic injection constant pressure device can be installed on the hot runner injection mold system.

Embodiment 3

[0018] Example 3: On the basis of Example 1, the large injection molded product in the hot runner injection mold uses a compressed gas top plate or multiple cylinder piston top plates to push the large injection molded product out of the mold; or uses an air pump to lift the injection molded product. Out of the mold ----- the mold with dense small cavities as reinforcing ribs can be made into the shape of the valve core cover of the automobile engine, and the steam pressure is blown from the side of the rod core to lift the core cover from the gap of the cover. And make more gas enter the mold cavity and hold up the product. It is convenient for the product to be released from the mold.

Abstract

The invention relates to the device and injection molding method used to process precise injection molding for large scale plastics. It includes the following steps: using one, two, or many large scale oil presses to process mode locking for hot runner injection die; injecting hot fused plastic from discharge gate of the injection molding cylinder into the die by one way valve; closing the one way valve; injecting the hot fused plastic into the injection molding cylinder again to reserve; cooling the product in the injection die; opening the hot runner injection die by compressed gas hanging or many air cylinder piston hanging to take out the large scale injection molding products.

Description

technical field [0001] The invention relates to equipment capable of precise injection molding of large plastic products, an injection molding method and injection molding products, belonging to the field of equipment manufacturing of large injection molding products. Background technique [0002] The applicant’s authorized announcement number is CN1274480C, and the name is "Filter Press Plastic Diaphragm Injection Molding Method and Equipment". Enter the cavity of the plastic diaphragm mold to form, cool and shape, and then open the mold to take out the diaphragm. The fly in the ointment is: this equipment and method are only suitable for the manufacture of small-scale injection molding products of light weight, but then can't realize with the way of injection molding for large-scale products, for example: (1) such as building materials aspect has: all kinds of house walls, partition walls, Floors, pallets, beam tops and other parts cannot be realized by injection molding ...
