Novel latex sponge shaping device

Abstract

The invention relates to a novel latex sponge shaping device comprising a workbench, supporting legs, a lower mold and an upper mold. The supporting legs are arranged at four corners of the bottom surface of the workbench, the lower mold is fixedly connected to the upper surface of the workbench, and the upper mold is arranged above the lower mold. Air cylinders are arranged at the middle positions of the two sides of the upper surface of the upper mold, and the air cylinders are fixed to the upper surface of the lower mold through piston rods. According to the latex sponge shaping device, theupper mold and the lower mold are arranged, an infrared radiator is arranged in a cavity of the upper mold, and according to the design, due to the fact that the infrared radiator is large in power,good in radiation effect and capable of penetrating through the surface of a product and transferring heat into the product, foam holes are shaped before the foam in the product is broken, so that theinner foam holes of the product are uniform and dense, and the resilience and the comfort degree of the product are increased.

Description

technical field [0001] The invention belongs to the technical field of sponge shaping equipment, in particular to a novel latex sponge shaping device. Background technique [0002] The traditional way of setting latex sponge is to use ordinary high-temperature quartz tube to heat. The heating effect is average, and it can only form a thin film on the surface of the latex, but cannot penetrate into the interior of the latex. In the process of mechanical foaming of latex, the foam produced has a certain time limit. Over this period of time, the foam will automatically burst, so the traditional quartz tube heating method cannot shape the latex material internally, and the latex sheet produced , from the cross-section, the cell structure of the upper part and the lower part are inconsistent, the cells cannot be finalized, the cells of the material have been broken before vulcanization, and the cells of the material are thick after molding, which seriously affects the comfort and...

Problems solved by technology

[0002] The traditional way of shaping latex sponge is to use general high-temperature quartz tube to heat. The heating effect is average. It can only form a thin film on the surface of the latex, but cannot penetrate into the interior of the latex.

In the process of mechanical foaming of latex, the foam produced has a certain time limit. Over this period of time, the foam will automatically burst, so the traditional quartz tube heating method cannot shape the latex material internally, and the latex sheet produced , from the cross-section, the cell structure of the upper part and the lower part are inconsistent, the cells cannot be finalized, the cells of the material have been broken before vulcanization, and the cells of the material are thick after molding, which seriously affects the comfort and performance of the material. When injecting into the mold cavity, more or less some air will be left; these airs are attached to the bottom of the cavity and expand into air bubbles after being heated, which will bring defects to the shaped latex sponge, so it is necessary to carry out design improvement
