Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator accessories production equipment, in particular to an injection mold for a refrigerator end cover. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. There are compressors and ice makers in the cabinet or box for ice making, and storage boxes with refrigeration devices in the refrigerator. The refrigerator is mainly composed of accessories such as a cabinet body, a door body, a refrigeration system and an electrical system. Many of the accessories, such as the end cover, are one of the important parts of the refrigerator door body. It not only plays the role of forming the door frame of the refrigerator door body, but also helps to install some small functional components.

[0003] At present, the existing production methods for end caps are to use a specific mold for casting and then molding. The required injection mold is a device that extrudes the refrigerator shell at high temperature. It has a simple structure and is easy to operate. When the injection molding work is completed, a demolding process is required. The current demolding method is to manually use tools to demold it. This demolding method is inefficient and will cause damage and injury to the end cap or people. In addition, because the product will fit with the four walls of the mold after molding, it will be difficult to take out. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing production methods of end covers are to use a specific mold for casting and then molding. The required injection mold is a device that extrude and mold the refrigerator shell by high temperature. It has a simple structure and is easy to operate. When the injection molding work is completed, a demoulding process is required. The current demoulding method is to demould it manually using tools. Such a demoulding method is inefficient and may cause damage and injury to the end cover or people. In addition, because the product will fit with the four walls of the mold after molding, it will be difficult to take it out. Therefore, an injection mold for a refrigerator end cover is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The invention discloses an injection mold for an end cover of a refrigerator, comprising a mold body and a base. The mold body is divided into a first mold and a second mold. A protruding convex head is arranged on the left middle side at both ends of the first mold, and a recessed groove is arranged on the right middle side. Both ends of the second mold are arranged opposite to the two ends of the first mold. A bottom plate is arranged at the bottom of the mold body, an end cover bottom mold is arranged on the top of the bottom plate, an electric push rod is placed on the top of the base, a placement plate is installed at the output end of the electric push rod, and ejector rods are installed at both ends of the placement plate.

[0007] Preferably, positioning holes are opened at the four corners of the mold body, supports are installed at the four corners of the top of the base, and positioning columns are fixedly installed on the top of the supports.

[0008] Preferably, the positioning column matches the positioning hole, and the upper middle portion of the positioning column is configured as a thread shape.

[0009] Preferably, the positioning column is located above the positioning hole and is threadedly connected with a bolt.

[0010] Preferably, two circular holes are provided on the bottom plate, and the top plate is mounted on one end of two top rods passing through the circular holes on the bottom plate.

[0011] Preferably, a square groove is provided on the bottom plate, and the height and width of the top plate match the square groove.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model separates the mold body into a first mold and a second mold, and sets protruding concave heads and recessed grooves at both ends thereof. The above settings make it convenient to assemble and disassemble the first mold and the second mold. When demolding, it only needs to be separated, which can avoid damage to the mold and the product and is simple and convenient.

[0014] 2. After the mold is separated, the top plate is driven to rise by driving the electric push rod and the ejector rod, and the end cover is lifted from the bottom plate through the top plate to avoid adhesion to the inner wall of the mold, which facilitates demoulding and improves production efficiency.
