Novel water heater thin double-liner foaming mold and foaming method

Abstract

The invention relates to the technical field of foaming molds, and discloses a novel water heater thin double-liner foaming mold and a foaming method.The novel water heater thin double-liner foaming mold comprises a machine body frame, a bottom table is fixedly installed at the bottom of the machine body frame, a micro air cylinder is fixedly installed at the top of the machine body frame, and a foam blocking rod frame is fixedly installed at the tail end of the micro air cylinder; and a main tray and an auxiliary tray are fixedly installed on the upper surface of the bottom table, and anti-abrasion devices are arranged at the bottom of the main tray and the bottom of the auxiliary tray correspondingly. In the foaming material injection process, a vertical frame is pushed by an air cylinder to move upwards, short connecting rods on the two sides of the vertical frame are opened at the same time, and under the action of a fixed frame plate, movable push plates at the left ends of the short connecting rods move leftwards to make contact with a water heater body and then continuously extrude a machine body frame till the short connecting rods are completely opened; therefore, deformation of the water heater body in the foaming process is avoided, and foaming forming stability is improved.

Description

technical field [0001] The invention relates to the technical field of foaming moulds, in particular to a new type of thin double-chamber foaming mould for water heaters and a foaming method. Background technique [0002] In the electric water heater industry, the way to keep the inner tank warm is to wrap the inner tank with styrofoam, which is equivalent to putting a piece of clothing on the inner tank to keep the temperature of the hot water inside the inner tank. The foaming mold is used to cover the surface of the inner tank, and the size of the water heater is large, and a new type of thin double-tank foaming mold for the water heater is required to adapt. [0003] At present, the main body of the foamed electric water heater is easily deformed during the molding process, resulting in unstable foaming. After the foaming is completed, due to the difference in the size of the inner tank, the one-time molding is limited. In the process of pushing out the inner tank, the ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of water heater thin-type double-tank foaming mold and foaming method, which has the advantages of not easy deformation of the main body and high foaming molding stability, and solves the problem of easy wear and tear on the outer surface and the problem of molding The quality of the inner tank of the water heater is too low
