Description

Technical Field

[0001] The utility model relates to a die casting molding device, in particular to a fixed die ejection mechanism for preventing product deformation. Background Art

[0002] Complex-shaped die-castings have many slider mechanisms to ensure the molding of the castings. The slider mechanisms are all designed on the movable mold side, so the runner can only be designed on the fixed mold side. Since the fixed mold side itself has no ejection mechanism, when the movable and fixed molds are opened, the runner clamping force is on the fixed mold, which can easily cause mold deformation. Therefore, an ejection mechanism needs to be designed on the fixed mold side. When the fixed mold space is small, a simple and reliable mechanism needs to be designed to ensure the stability of the ejection movement. Utility Model Content

[0003] The purpose of the utility model is to provide a fixed die ejection mechanism for preventing product deformation, which has a simple structure, low production cost and high product qualification rate, so as to solve the problems in the prior art.

[0004] The technical solution of the utility model is: a fixed mold ejection mechanism for preventing product deformation, wherein the fixed mold ejection structure is arranged on the fixed mold side, and the fixed mold ejection mechanism includes a casting, a runner, a pressure block and multiple telescopic mechanisms;

[0005] The casting is arranged on the fixed mold, the flow channel is arranged on the side of the fixed mold, and the multiple telescopic mechanisms are arranged between the pressing block and the casting;

[0006] The telescopic mechanism includes a spring, a spring fixing rod and a top block. The lower end of the top block is arranged on the fixed mold, the upper end of the top block is fixedly connected to the spring fixing rod, the upper end of the spring is connected to the pressure block, and the lower end of the spring is fixedly connected to the spring fixing rod.

[0007] The beneficial effects of the utility model are: simple structure, low production cost, high product qualification rate, and avoidance of product size deviation caused by mold deformation. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural diagram of the present utility model.

[0009] In the figure, 1 is the casting, 2 is the runner, 3 is the top block, 4 is the spring fixing rod, 5 is the spring, and 6 is the pressure block. DETAILED DESCRIPTION

[0010] A fixed mold ejection mechanism for preventing product deformation, wherein the fixed mold ejection structure is arranged on the fixed mold side and comprises a casting 1, a runner 2, a pressing block 6 and a plurality of telescopic mechanisms;

[0011] The casting 1 is arranged on the fixed mold, the runner 2 is arranged on the side of the fixed mold, and the multiple telescopic mechanisms are arranged between the pressing block 6 and the casting 1;

[0012] The telescopic mechanism includes a spring 5, a spring fixing rod 4 and a top block 3. The lower end of the top block 3 is set on the fixed mold, the upper end of the top block 3 is fixedly connected to the spring fixing rod 4, the upper end of the spring 5 is connected to the pressure block 6, and the lower end of the spring 5 is fixedly connected to the spring fixing rod 4.

[0013] The working process of the utility model is: when the movable mold and the fixed mold are in the mold closing state, the movable mold presses the ejector block 3, thereby putting the spring 5 in a compressed state; at the moment when the movable mold and the fixed mold are opened, the movable mold moves upward, so that the compressed spring 5 and the ejector block 3 have space to move, and the ejector block 3 pushes out of the runner 2 as the movable mold moves until the spring 5 is in a natural state and all the elastic force is released; when the movable mold and the fixed mold are closed, the movable mold approaches the pressure block 6 and continuously compresses the spring 5, so that the ejector block 3 and the spring 5 return to the mold closing state.
