Problems solved by technology

One is that the mold is fixed on the rotary disc, and the injection nozzle is injected from the back of the jaw of the jaw-type mold clamping mechanism. Lower clamping
Due to the limitation of the height of the injection nozzle, the height of the mold cannot be changed, which increases the difficulty of manufacturing molds for shoe sole products with various styles and specifications, which is not conducive to the production of many varieties and styles of shoe products in the current market; 2. Because the injection nozzle is from the back of the jaw If the screw barrel is too long, the material in the screw barrel will be overheated during pre-molding, which will easily lead to overheating of the material, easy discoloration of the sole product, and a high rate of defective products; In the middle of the support plate of the mechanism, it brings inconvenience to operation, repair and maintenance
The other is that the screw barrel screw is set above the gantry-type mold clamping mechanism. The disadvantage is: due to the influence of the screw radius and the thickness of the upper template, the material channel of the discharge port and the injection nozzle are lengthened a lot. After the injection is completed, When the mold is opened and turned, it is easy to produce cold material in the injection nozzle and the material channel. When the next mold is injected, the qualified rate of the product will drop. Therefore, it is the concern of every customer in the market to solve the shortcomings of the above machines. Where to pursue

Abstract

The present invention relates to plastic shoe sole producing apparatus, and is especially one kind of air blowing and plastic foaming injection machine for producing shoe sole. The machine includes one injecting mechanism, one mold clamping mechanism, one turntable and one turning disc mechanism. The mold clamping mechanism includes one mold clamping pressure cylinder and one jaw type mold rack; and the injecting mechanism has injecting nozzle aligned to the jaw of the mold rack. The machine of the present invention has the advantages of high product quality, convenient maintenance, capacity of producing different products, etc.

Description

technical field [0001] The invention relates to production equipment for producing plastic soles, in particular to a plastic blowing and foaming injection machine for shoes. Background technique [0002] There are two structural forms of plastic blowing and foaming injection machines for shoes commonly used in the Chinese market (including those made in Taiwan). One is that the mold is fixed on the rotating disc, and the injection nozzle extends into the injection from the back of the jaw of the jaw-type clamping mechanism. Clamp down. Due to the limitation of the height of the injection nozzle, the height of the mold cannot be changed, which increases the difficulty of manufacturing shoe sole products of various styles and specifications, which is not conducive to the production of various types and styles of shoe products in the current market; 2. Because the injection nozzle is from the back of the jaws If the screw is too long, the material in the barrel is overheated ...
