The invention relates to a foaming and film coating device for producing expansion valve heat preservation cotton, and belongs to the field of foaming equipment. The foaming and film coating device comprises a lower mold frame, an upper mold frame, a lower mold mounted on the lower mold frame and an upper mold mounted on the upper mold frame, wherein the lower mold comprises a lower mold base anda lower pressing frame; the lower mold base is fixed to the lower mold frame; a first forming boss is arranged in the middle of the face, away from the lower mold frame, of the lower mold base; the lower pressing frame is hinged to one edge of the lower mold base; the first forming boss is located in an upper pressing frame; the upper mold comprises an upper mold base and the upper pressing frame;the upper mold base is fixed to the upper mold frame; a second forming boss is fixedly arranged in the middle of the face, away from the upper mold frame, of the upper mold base; the upper pressing frame is hinged to one edge of the upper mold base; the second forming boss is located in the lower pressing frame; and a foaming cavity is formed between the first forming boss and the second formingboss. In the foaming production process, the production technology of coating the surface of foaming sponge with a PU film is achieved, foaming and film coating are completed at the same time, and theproduction efficiency is improved.
Description
technical field [0001] The present application relates to the field of foaming equipment, in particular to a foaming and coating equipment for producing thermal insulation cotton for expansion valves. Background technique [0002] The expansion valve is a relatively common component, which is widely used in the refrigeration system, so that the medium-temperature and high-pressure liquid refrigerant can be throttled into a low-temperature and low-pressure wet steam, thereby controlling the flow rate of the valve. The expansion valve insulation cotton is mainly composed of foam sponge and the upper and lower PU films wrapped on the outside of the foam sponge. The expansion valve insulation cotton is used to keep the expansion valve warm, reduce the impact of the ambient temperature on the expansion valve, and ensure expansion. The performance of the valve. [0003] The relevant announcement number is the Chinese utility model patent of CN207190127U, which discloses a kind of...
