Mold for vertical pouring of organic glass and method for vertically pouring organic glass by the mold

Abstract

The invention relates to a mold for vertical pouring of organic glass and a method for vertically pouring organic glass by the mold. The mold comprises multiple adhesive tape frames and multiple water tanks. Each one of the adhesive tape frames is vertically arranged between corresponding two of the multiple water tanks at an interval in a seal clamping state. Each one of the adhesive tape frames is vertically arranged between corresponding two of the multiple water tanks at an interval in a seal clamping state and different reaction heat sources are provided to the water tanks so that polymerization molding temperature requirements of raw materials in the adhesive tape frames are satisfied and thus vertical pouring and integrated curing molding of organic glass are realized. The mold has a simple and compact structure, is convenient for use, saves time and labor, can effectively guarantee molding quality, production efficiency and a production cost, and can be widely used for pouring polymerization molding of acrylic acid and acrylates.

Description

technical field [0001] The invention relates to a molding and pouring device, in particular to a vertical pouring mold for organic glass used for vertical casting in the production of organic glass and a method for pouring organic glass. Background technique [0002] PMMA is a polymer obtained by the polymerization of acrylic acid and its esters, collectively referred to as acrylic resin, and the corresponding plastics are collectively referred to as polyacrylic plastics, among which polymethyl methacrylate, commonly known as plexiglass, is the most widely used. The production process of traditional plexiglass is as follows: two templates are clamped relative to each other and polymethyl methacrylate is injected into the clamping cavity, the two clamped templates are sent into the water pool for thermal polymerization, and then formed by high-temperature molding and demoulding. , the shortcomings of this type of technology are: the clamping operation of the clamping template...

Problems solved by technology

The production process of traditional plexiglass is as follows: two templates are clamped relative to each other and polymethyl methacrylate is injected into the clamping cavity, the two clamped templates are sent into the water pool for thermal polymerization, and then formed by high-temperature molding and demoulding. , the shortcomings of this type of technology are: the clamping operation of the clamping template before the reaction injection and the molding demoulding is cumbersome, the clamping requirements are high, time-consuming and labor-intensive, and in order to ensure the molding quality, when the template is moved and fed into the reaction process Among them, the requirements for mobile operation and clamping are further improved, which is not conducive to fast and stable mass production
