Supporting and positioning device for refrigerator foaming internal mold

Abstract

The invention discloses a device for supporting and positioning a refrigerator foaming internal mold, which comprises a translation mechanism and a linkage support mechanism arranged on the translation mechanism, wherein the linkage support mechanism comprises a slider mechanism provided with a left ejector block, an upper ejector block and a right ejector block, and a link mechanism connected with the slider mechanism and the translation mechanism for driving the three ejector blocks to move. The device for supporting and positioning the refrigerator foaming internal mold can be opened in the refrigerator foaming internal mold to support and position the refrigerator foaming internal mold, and can be shrunk rapidly after finishing foaming to be taken out successfully from the refrigerator foaming internal mold, thereby speeding up the demoulding of the refrigerator foaming internal mold. Compared with the prior wood neutron for supporting and positioning the refrigerator foaming internal mold, the device is obviously more favorable for improving the production efficiency of the refrigerator foaming technology.

Description

technical field [0001] The invention relates to a support and positioning device for a foam inner mold of a refrigerator. Background technique [0002] The inner and outer molds for refrigerator foaming are necessary tooling used to complete the filling of polyurethane insulation materials between the inner liner of the refrigerator box and the outer shell of the box; The surface of the liner and the outer shell of the box are bonded to maintain the support for the refrigerator box, so that the liquid polyurethane can be continuously injected into the box, and finally the heat preservation and curing of the polyurethane can be realized. [0003] Since most of the existing refrigerator cabinets are of mid-range separation layer structure, there is often only one middle beam between the layers, and the rest are empty, which is easy to deform during the expansion process of polyurethane foam. In order to prevent this from happening , the existing method is to insert wooden neu...

Problems solved by technology

[0004] The purpose of the present invention is to provide a support and positioning device for the foaming inner mold of the refrigerator, which can be stretched in the foaming inner mold of the refrigerator, in view of the shortcomings of cumbersome assembly and low efficiency of the currently used wooden neutron positioning refrigerator foaming inner mold The foaming inner mold of the refrigerator is supported and positioned. After the foaming is completed, it can shrink quickly so that it can be removed smoothly from the foaming inner mold of the refrigerator, thereby speeding up the demoulding speed of the inner foaming mold of the refrigerator and greatly improving the production efficiency of the refrigerator foaming process
