Description

Technical Field

[0001] This utility model belongs to the field of shelving processing technology, and relates to a high-precision injection mold for a modular shelving unit. Background Technology

[0002] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product. Traditional shelves are also processed using injection molds. After the shelf plastic parts are molded, they are pushed out by ejector pins. However, the existing ejector pin structures are all integrally molded, which makes replacement more costly and difficult. Summary of the Invention

[0003] The purpose of this invention is to provide a high-precision injection mold for a modular shelving unit to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved through the following technical solutions: A high-precision injection mold for a modular shelving unit includes a base plate, a lower mold base, an upper mold base, and an upper ejector rod. The lower mold base is located at the top of the base plate, and a push plate is located between the lower mold base and the base plate. Multiple lower ejector rods are located at the top of the push plate. A first support seat is connected to the top side of each lower ejector rod via a connecting plate. A second support seat is located on the side of the first support seat. Inner grooves are formed inside the first and second support seats. A rotating ring is movably arranged inside the inner grooves. An upper ejector rod is fitted inside the rotating ring. A threaded head is connected to the bottom end of the upper ejector rod, and the threaded head is threaded into the mounting slot at the top of the lower ejector rod.

[0005] In the high-precision injection mold of the above-mentioned modular shelving unit, a clamping bolt is threadedly connected to the middle position of the connecting plate, and one end of the clamping bolt is pressed against the bottom position of the upper push rod.

[0006] In the above-mentioned high-precision injection mold for combined shelves, a pin frame is provided on one side of the bottom of the lower ejector rod, and a side support arm is movably installed inside the pin frame through a pin. A guide rod is sleeved on one end of the side support arm.

[0007] In the aforementioned high-precision injection mold for a modular shelving unit, the top end of the guide rod is connected to the bottom of the second support base, and a guide plate is provided on the outer side of the guide rod.

[0008] In the aforementioned high-precision injection mold for a modular shelving unit, a limiting groove is provided on the outer side of the upper ejector rod, and the guide plate slides inside the limiting groove. A limiting block is provided on one side of the inner side of the rotating ring, and the limiting block slides inside the limiting groove.

[0009] In the above-mentioned high-precision injection mold for combined shelves, the bottom end of the lower ejector rod is connected to a mounting base, and the mounting base is fixed to the top of the push plate. An upper mold base is provided at the top position of the lower mold base.

[0010] Compared with existing technologies, the advantages of this utility model's high-precision injection mold for modular shelving are: 1. This application features a segmented upper and lower push rod structure. When installing the upper push rod, the slidable rotating ring can be moved into the first support seat, and then the upper push rod can be pushed inward so that the threaded head at the bottom of the upper push rod is threaded into the installation groove. Then, the clamping bolt is rotated to clamp and limit the upper push rod. In this way, the installation of the upper push rod can be completed. The installation of the upper push rod is simple and efficient, and the support is stable.

[0011] 2. This application provides a second support seat on the side of the first support seat. When the upper push rod needs to be disassembled and replaced, the sliding rotating ring can slide from the inside of the first support seat to the inside of the second support seat, and then push the upper push rod downwards, causing the upper push rod to slide down. When the upper push rod slides down, it is supported and guided by the guide plate. The guide rod can also slide to drive the second support seat down, reducing the height of the upper push rod. Then the side support arm is tilted outwards, thereby causing the upper push rod on the side support arm to be laid horizontally. This makes it convenient to continue replacing the upper push rod.
