Problems solved by technology

[0003] However, there are deficiencies in the processing of traditional foaming molds. When the traditional foaming mold is processed, the bottom of the foamed product will stick to the surface of the mold due to the high temperature during processing, which makes the appearance of the product unattractive and brings inconvenience to use. Therefore, we propose a foaming mold processing method with high cleaning efficiency

Embodiment

[0020] When processing, first prepare the raw materials. The foaming raw materials are prepared from the following mass components: 40 parts of resin, 25 parts of rubber, 8 parts of toluene diisocyanate, 2 parts of silica airgel, 3 parts of foaming agent, and 0.5 parts of catalyst 1 part, 1 part of surfactant, 2 parts of foam stabilizer, 3 parts of graphene, the catalyst is methyl alkylene diamine, and the surfactant is silicone oil to obtain the prepared raw materials; followed by foaming and stirring, the prepared The foaming agent, catalyst, surfactant, and foam stabilizer in the raw materials are put into the foaming machine for stirring in turn, and then the resin, rubber, silica airgel and graphene are put into the blender for stirring to obtain a mixture , put the mixture into a foaming machine, add toluene diisocyanate to foam, stir and mix, let stand to react and foam, and get foamed foam; then brush the oil layer and place the film layer, and the foam mold that needs ...

Abstract

The invention discloses a foaming mold processing method with high cleaning efficiency. The foaming mold processing method with high cleaning efficiency comprises the following steps of firstly, preparing raw materials, wherein the foaming raw materials are prepared from the following components in parts by mass: 40 to 45 parts of resin, 20 to 30 parts of rubber, 8 to 12 parts of toluene diisocyanate, 2 to 4 parts of silica aerogel, 2 to 3 parts of blowing agents, 0.5 to 2 parts of catalysts, 1 to 1.5 parts of surfactants, 2 to 4 parts of foam stabilizers and 3 to 5 parts of graphene. According to the foaming mold processing method with high cleaning efficiency, through the steps of preparing the raw materials, foaming and stirring, brushing an oil layer and placing a membrane, performinginjection molding, performing curing and the like, the processing efficiency of a foaming mold is increased; and meanwhile, an oil brushing layer is arranged and the membrane is placed, so that the foaming mold can quickly clean the residual inside the mold during a machining process, the oil brushing layer can effectively avoid the adhesion of a product and the mold, and the membrane is added toenable the mold to be quickly taken out without adhesion after machining and shaping.

Description

technical field [0001] The invention belongs to the technical field of mold processing, and in particular relates to a foaming mold processing method with high cleaning efficiency. Background technique [0002] The mold for foam molding is a plastic foam mold, which is to directly fill the foamable resin into the mold, heat it to melt, and form a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed, and the nuclei grow. There are three commonly used foaming methods: physical foaming method, chemical foaming method and mechanical foaming method; [0003] However, there are deficiencies in the processing of traditional foaming molds. When the traditional foaming mold is processed, the bottom of the foamed product will stick to the surface of the mold due to the high temperature during processing, which makes the appearance of the product unattractive and brings inconvenience to use. Therefore, we propose a foaming mold processing ...
