Refrigerator drawer injection mold

Abstract

The invention discloses a refrigerator drawer injection mold. The refrigerator drawer injection mold comprises a fixed bottom plate and a movable top plate. Guide columns are welded to the four corners of the fixed bottom plate correspondingly. The movable top plate is movably mounted on the four guide columns. A lower mold body is arranged on the fixed bottom plate. An injection mold cavity is formed in the middle of the lower mold body. A first storage groove is formed in the center of the bottom of the injection mold cavity. A top extension plate is movably mounted in the first storage groove. A piston rod of a top extension air cylinder is fixedly connected with the bottom of the top extension plate. The top extension air cylinder is fixedly mounted to the outer side of the bottom of the fixed bottom plate. An upper mold body is arranged at the position, over the lower mold body, of the movable top plate. An inner mold body is arranged at the position, close to the lower mold body,of the upper mold body. The refrigerator drawer injection mold is novel in design, simple in structure and convenient to use, products can be demolded rapidly, deformation and cracking caused by bonding of the products and the mold are avoided, and the injection efficiency of the mold is improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for a refrigerator drawer. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. The volume of household refrigerators is usually 20-500 liters. In 1910, the world's first compression refrigeration household refrigerator came out in the United States. In 1925, the Swedish Lido Company developed a household absorption refrigerator. In 1927, General Electric Company of the United States developed a fully enclosed refrigerator. In 1930, the air-cooled continuous diffusion absorption refrigerator with different heating methods was put on the market. In 1931, a new typ...

Problems solved by technology

[0003] There are multiple drawers in the refrigerator for storing food. The drawers of the refrigerator are formed by injection molding. However, after the existing injection molds are molded, it is difficult to demold the drawers, which often causes the drawers to be attached to the upper mold. When the lower mold is separated, the drawer will follow the movement of the upper mold, causing the drawer to break and deform. Therefore, we have designed a refrigerator drawer injection mold to solve the above problems
