Problems solved by technology

[0004] Temperature problem: The material is easy to burn and change color, the production temperature is low, the foaming is not good, and the product is too heavy; the production temperature is too high, the material is easy to burn and change color, and the surface is blistered
[0005] Foaming problem: the foaming of the cells is not uniform, the front and rear are loose and there are large holes, and the foaming in the middle is not good. The blowing process is carried out during the injection molding process, and the working time of the blowing is long, which prolongs the production cycle and leads to low production efficiency.

Abstract

The invention discloses a PVC blowing slipper injection mold which comprises a fixed mold base, a movable mold base and a plastic mixing crushing mechanism, wherein the plastic mixing crushing mechanism comprises an accommodating reaction cylinder and a drive motor; the drive motor is connected with a squeezing screw; a thermal insulating panel is arranged at one end of the squeezing screw and isconnected with a displacement air cylinder; a movable sliding block is mounted on the lower surface of the drive motor; a sliding rail is further arranged on the inner wall of the accommodating reaction cylinder; the squeezing screw is sequentially divided into a crushing section, a melting stirring section and a squeezing section from right to left; the accommodating reaction cylinder is providedwith a friction bulge; the accommodating reaction cylinder is provided with subsection heating mechanisms at the melting stirring section and the squeezing section separately; and an air blowing pipeis further arranged on the accommodating reaction cylinder. The subsection heating manner is adopted to avoid the situation that plastic is burnt; an air blowing mechanism is added to increase the foaming quantity; and water-cooling and air-cooling manners are adopted to carry out air blowing foaming treatment and efficient cooling function, so that the injection molding period is shortened and the operating convenience is also improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold and method for injection molding of plastic slippers. Background technique [0002] Air-blown slippers are the latest popular new type of slippers in the world. According to the trend of plastic shoes, after long-term production and use verification, the current air-blown slippers have excellent thermal stability effects, and can effectively and smoothly pass through high-temperature processing at about 200 degrees, ensuring Produce high-quality air-blown slippers, the cell structure of the cut surface of the big bottom is like EVA slippers, no large holes, good shape, less additives, low cost, simple process, easy to use, no smell, overcome the traditional high-foaming PVC Slippers and soles have many shortcomings, but they are comfortable to wear and light, which is an unusual qualitative leap in the production of slippers. [0003] Since air-blown sl...
