Small-size refrigerator door seal welding assembly die

Abstract

The invention discloses a small-size refrigerator door seal welding assembly die. The small-size refrigerator door seal welding assembly die is characterized by comprising a left front die assembly, aright front die assembly, a left rear die assembly and a right rear die assembly, wherein the left front die assembly is located on the left side of the right front die assembly, the right rear die assembly is located on the rear side of the right front die assembly, the left rear die assembly is located on the left side of the right rear die assembly, the left front die assembly, the right frontdie assembly, the left rear die assembly and the right rear die assembly are integrally distributed in a shape of matts, the right front die assembly is provided with a front die base, a front die frame, a front die pressing plate and a front die, and the right rear die assembly is provided with a rear die base, a rear die frame, a rear die pressing plate and a rear die. The small-size refrigerator door seal welding assembly die is simple in structure, small and exquisite in size, capable of directly welding door seal rubber strips with the length of 150mm to 300mm, good in welding quality, capable of synchronously welding two sets of adjacent door seal rubber strips and high in production efficiency.

Description

technical field [0001] The invention relates to the field of welding molding devices, in particular to a small-sized refrigerator door seal welding molding. Background technique [0002] The refrigerator door seal is an indispensable and important component to ensure the sealing, heat preservation and energy saving of the refrigerator. With people's continuous pursuit of the quality of refrigerators, the functions of refrigerators are becoming more and more abundant. With the enrichment of refrigerators’ functions, the structural design of refrigerators has become more and more novel and diversified. There are more and more small-sized doors and drawers in refrigerators. Most of them are between 150mm and 300mm. In the past, such small-sized door seals for opening doors and drawer refrigerators usually did not weld the corners or glued the corners by vulcanization, resulting in uneven four corners of the small-sized refrigerator door seals and weak bonding, which seriously...

AI Technical Summary

Problems solved by technology

In the past, such small-sized door seals for opening doors and drawer refrigerators usually did not weld the corners or glued the corners by vulcanization, resulting in uneven four corners of the small-sized refrigerator door seals and weak bonding, which seriously As a result, the overall sealing, heat preservation and energy saving effect of the refrigerator is unqualified

At present, there are the following problems in the actual use of ordinary welding sets: 1. The overall design of ordinary welding sets is unreasonable. The welded sets are bulky and take up a lot of space. 2. Ordinary welding molds use reverse feeding, which is inconvenient to operate, low feeding efficiency, and labor-intensive; 3. The front and rear molds in ordinary welding molds cannot be replaced. Weld the door seal strips with different external contours; 4. Ordinary welding molds cannot weld two adjacent door seal strips at the same time, and the production efficiency is low
