Fully automatic moulding press for moulding small plastic parts

Abstract

The invention discloses a fully automatic moulding press for moulding small plastic parts, which comprises a power device, a mould pressing device and a mould cooling system, wherein the mould pressing device comprises a main shaft, a lower bottom plate, a mould pressing seat and an upper cover board; the lower bottom plate is provided with a mould closing guide rail and a mould opening guide rail; the mould pressing seat comprises an upper turntable and a lower turntable which are connected into a whole by a spacer bush, and a plurality of mould pressing parts circumferentially uniformly distributed on the upper and lower turntables; each mould pressing part comprises an upper mould pressing part arranged on the upper turntable and a lower mould pressing part arranged on the lower turntable; the upper cover board is fixedly connected with the lower bottom plate through an upright post; and the center of a lower lateral surface of the upper cover board is fixedly provided with a centerrotary valve connected with the main shaft, and simultaneously one side of the lower lateral surface of the upper cover board is provided with a lug. The invention provides the fully automatic moulding press for moulding the small plastic parts, the mould pressing seat thereof adopts a double-layer structure, the mould pressing parts have less fittings, the failure rate is low when the fully automatic moulding press works, and the maintenance is convenient.

Description

technical field [0001] The invention relates to a small plastic part molding processing machine, in particular to a fully automatic small plastic part molding molding machine. Background technique [0002] The traditional production and processing of small plastic parts generally adopts injection molding process, which has been gradually eliminated by manufacturers due to problems such as low processing efficiency, large waste of raw materials, and poor surface smoothness of finished products. At present, there are many kinds of latest small plastic parts processing machines, such as the Chinese utility model patent with the publication number CN2521018, which is a plastic bottle cap forming molding machine. The whole device includes a molding device and a power device. device connection, such as figure 1 and figure 2 As shown, the molding device is composed of a main shaft 26', a molding seat 27', an upper cam connecting plate 28' and an upper cam 29', and several moldin...

AI Technical Summary

Problems solved by technology

But at the same time, there is a problem of complex structure in the entire molding device. The molding seat is a four-layer board structure, and there are too many accessories for the molding parts, resulting in high manufacturing costs, high failure rates, and difficulties in machine maintenance and maintenance.

In addition, the clamping and opening of the upper and lower molds of each molded part are controlled by rails, and the resistance of the molded seat is relatively large when it is running, which makes it difficult to control the precision of the product.

In addition, the cooling system
