Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] to produce figure 1 Take the yoga mat as an example, the main part 301 is pink, the middle part 302 is white, and the other part 303 is black. EPP particles of these three colors are used as raw materials during production.

[0044] Such as figure 2 The foaming mold shown includes an upper mold 1 and a lower mold 2, the upper mold 1 is a convex mold, the lower mold 2 is a concave mold, and the yoga mat 3 is formed after the upper mold 1 and the lower mold 2 are closed during molding. In the cavity, the contour of the molding cavity at this time is consistent with the shape of the yoga mat 3 .

[0045] Such as image 3 and Figure 4 The upper mold 1 shown inclu...

Abstract

The invention discloses a foaming mold and a composite foam forming method. The mold comprises an upper mold and a lower mold, wherein the upper mold comprises an upper template, a movable plate, a cylinder and a filling hole; a plurality of pins are arranged on the movable plate; the pins are distributed on the surface of the movable plate according to product patterns, and every two pins are spaced in a set distance; jacks which are in one-to-one correspondence with the pins and are inserted into each other are formed in the upper template; the lower mold is opposite to the upper mold and is provided with a lower template; a molding cavity used for molding the product is formed in the upper template and / or the lower template; after die assembly, the outline of the molding cavity is consistent with the appearance of the product; the movable plate makes the pins move along the jacks under drive of the cylinder; when the upper template is tightly attached to the movable plate, the pins stretch into the molding cavity of the molded product. According to the foaming mold and the composite foam forming method, foamed products with different colors and patterns can be molded at a time, the production efficiency is relatively high, the mold number is reduced, and the production cost is saved.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for foaming. [0002] The invention also relates to a foam molding method, in particular to a foam composite molding method. Background technique [0003] The foam produced by the prior art is often a single color and a single material. If you want to make a patterned foam product, you need to mold the parts of different colors separately and then bond them together, such as figure 1 The yoga mat shown has a pink body with a half white and half black figure in the middle. [0004] If foaming raw materials of different colors or materials can be integrally molded in the same mold, and the product has a pattern that meets the requirements, the production efficiency will be greatly improved and the production cost will be reduced. However, the molds in the prior art cannot be molded at one time. Clear-cut, foamed product with a multi-coloured pattern. Contents of the invention [0005] The tech...
