Polyurethane heat preservation sponge plate forming and manufacturing process

Abstract

The invention provides a polyurethane heat preservation sponge plate forming and manufacturing process, which comprises a mounting bottom plate, supporting legs, a supporting plate, a positioning mechanism and a distance adjusting mechanism, and can solve the problems that in the polyurethane heat preservation sponge plate forming and manufacturing process, a mold for forming operation needs to bemanually positioned and sealed; in addition, the number of polyurethane heat preservation sponge plates which usually need to be machined is large, a plurality of sponge plates are difficult to machine at the same time in traditional forming machining operation, the labor intensity of manual operation is high, the working efficiency of machining operation is reduced, and the size of a sealing cavity used for forming operation is difficult to adjust in real time according to actual production requirements, it is guaranteed that the sponge plates of different shapes can be machined, gaps in theforming cavity are difficult to effectively seal in the forming process, and the problems that excessive burrs are generated due to the fact that the gaps are too large, and the forming cavity is more difficult to open automatically after forming operation are solved.

Description

technical field [0001] The invention relates to the technical field of forming and processing of sponge boards, in particular to a molding and manufacturing process of polyurethane thermal insulation sponge boards. Background technique [0002] Polyurethane insulation sponge board is a porous material with good water absorption and can be used for cleaning items. It has the characteristics of heat preservation, heat insulation, sound absorption, shock absorption, flame retardancy, anti-static, and good air permeability. [0003] In the manufacturing process of polyurethane thermal insulation sponge board, it is often necessary to produce a specific shape of sponge board by mold molding to meet the actual use needs of some special occasions. The following problems: a. During the molding and manufacturing process of polyurethane thermal insulation sponge board, the mold for molding operation is often manually positioned and sealed. During this period, due to the large size and...

Problems solved by technology

[0003] In the manufacturing process of polyurethane thermal insulation sponge board, it is often necessary to produce a specific shape of sponge board by mold molding to meet the actual use needs of some special occasions. The following problems: a. During the molding and manufacturing process of polyurethane thermal insulation sponge board, the mold for molding operation is often manually positioned and sealed. During this period, due to the large size and weight of the mold, it is difficult to stabilize it Effective positioning and sealing operations, and usually there are a large number of polyurethane insulation foam boards that need to be processed. It is difficult to process multiple foam boards at the same time in traditional molding operations. The labor intensity of manual work is high, which reduces the work efficiency of processing work. b .During the molding and processing of traditional polyurethane thermal insulation sponge boards, it is difficult to adjust the volume of the sealing cavity used for molding operations in real time according to actual production needs, so as to ensure that sponge boards of different shapes can be processed, and it is also difficult to adjust the inside of the molding cavity during the molding process. Effectively seal the gap part of the gap to avoid excessive burrs caused by excessive gaps, and it is even more difficult to automatically open the molding cavity after the molding operation, which is convenient for manual removal of the processed sponge board and improves the operation of polyurethane thermal insulation sponge board molding processing efficiency
