Description

Technical Field

[0001] The utility model relates to the technical field of copper piece injection molding, in particular to a copper piece placing jig for injection molding production. Background Art

[0002] Injection molding is a method for producing industrial products. Injection molded parts refer to various injection molded products produced by injection molding machines, including various packaging, parts, etc. The choice of plastic parts is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product. Injection molded parts are generally made by compression molding, transfer molding, and injection molding. Lamination, compression molding, and thermoforming are used to shape plastic on a flat surface. During the product processing, copper parts are currently placed into the mold manually, which is slow and unsafe. Sometimes the copper parts to be placed are located deep, making placement difficult and inaccurate, resulting in long injection molding times and reduced work efficiency.

[0016] In order to make the technical solution more clear to those skilled in the art, Figure 1 -3 Detailed description of the technical solution of this utility model:

[0017] A copper part placement jig for injection molding production, comprising a handle 1, an upper fixed plate 2 connected to the handle 1, a limit buffer mechanism 3 arranged on the upper fixed plate 2, a lower fixed plate 4 arranged below the upper fixed plate 2, positioning columns 5 arranged on the upper fixed plate 2 and the lower fixed plate 4, a limit cylinder 6 arranged on the lower side of the lower fixed plate 4, and an ejection mechanism 7 arranged on the upper fixed plate 2 and the lower fixed plate 4. The lower end of the handle 1 is fixedly connected to the upper surface of the upper fixed plate 2, the upper fixed plate 2 and the lower fixed plate 4 are connected by the limit buffer mechanism 3 and the positioning column 5, the upper end of the limit cylinder 6 is fixedly connected to the lower fixed plate 4, and the ejection mechanism The upper end of 7 is fixedly installed on the lower end of the upper fixed plate 2. When working, the device is placed vertically, and the copper parts to be placed are placed on the ejection mechanism 7. Then the handle 1 is controlled to move the device, and the product is moved to the mold position for mold opening. Then, it is positioned through the positioning column 5 and the limiting cylinder 6. Then the handle 1 is pressed, and the upper fixed plate 2, the positioning column 5, and the ejection mechanism 7 move. The ejection mechanism 7 pushes the product into the mold. During this process, the limiting buffer mechanism 3 works, and then the device is moved away, and then the mold is closed and injection molding is completed. The operation is convenient and the use effect is good. The product can be reset through the limiting buffer mechanism 3 for subsequent reuse.

[0018] Among them, one end of the positioning column 5 is fixedly connected to the upper fixed plate 2, and the positioning column 5 passes through the upper and lower surfaces of the lower fixed plate 4 and is connected to it through a bearing. The positioning column 5 can position the device and the mold to facilitate the subsequent ejection operation of the copper part, and the limiting cylinder 6 can limit the device.

[0019] The structure of the limit buffer mechanism 3 is described in detail below. The limit buffer mechanism 3 includes limit screws 31 arranged around the bottom of the upper fixed plate 2 and a spring sleeved on the limit screws 31. The limit screws 31 are connected to the upper fixed plate 2 and the lower fixed plate 4. One end of the spring is fixedly connected to the lower surface of the upper fixed plate 2, and the other end of the spring is fixedly connected to the lower fixed plate 4. When working, press the handle 1, the upper fixed plate 2, the positioning column 5, and the ejection mechanism 7 work to eject the product, and then stop pressing the handle 1. Under the action of the spring, the upper fixed plate 2, the positioning column 5, and the ejection mechanism 7 are reset.

[0020] The limiting cylinder 6 is hollow.

[0021] The structure of the ejection mechanism 7 will be described in detail below. The ejection mechanism 7 includes an ejector pin 71, a sleeve 72 arranged on the outside of the ejector pin 71, a push rod 73 arranged below the upper fixed plate 2, and a fixed slide rail 74 arranged below the lower fixed plate 4. The push rod 73 is slidably mounted on the fixed slide rail 74. The upper end of the ejector pin 71 is fixedly connected to the lower surface of the upper fixed plate 2, the sleeve 72 is fixedly mounted on the lower fixed plate 4, the lower end of the ejector pin 71 is accommodated in the sleeve 72 and slidably mounted therein, and one end of the copper piece rests on the lower surface of the sleeve 72. The lower end of the ejector pin 71 is connected to the copper piece, and the copper piece is placed on the fixed slide rail 74. Pressing the handle 1 causes the upper fixed plate 2 to move. The movement of the upper fixed plate 2 can drive the ejector pin 71 and the push rod 73 to move, thereby pushing the copper piece out until the copper piece is installed in the mold. In order to better limit the movement of the ejector pin 71 and the push rod 73, a sleeve 72 is designed, and a slide groove is provided on the fixed slide rail 74 for the push rod 73 to move. The lower end of the push rod 73 passes through the upper and lower surfaces of the lower fixed plate 4 and is in sliding contact with it.

[0022] Furthermore, during installation, the copper piece rests on the lower fixed plate 4, and a push column 75 is provided at a corresponding position on the upper fixed plate 2. One end of the push column 75 is fixedly installed on the lower surface of the upper fixed plate 2, and a square hole is provided on the lower fixed plate 4 for the push column 75 to pass through. When the upper fixed plate 2 moves, it can push the push column 75 to move, thereby cooperating with the ejector pin 71 and the push rod 73 to complete the ejection of the copper piece.

[0023] The above technical solutions only reflect the preferred technical solutions of the present utility model. Any changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present utility model and fall within the scope of protection of the present utility model.
