[0021] Hereinafter, with reference to the drawings, the preferred embodiments of the present invention will be described in detail to further illustrate the present invention.

[0022] First, in combination with Figures 1 to 4 Describe the mold according to an embodiment of the present invention, which is used in the process of secondary injection molding and has a wide range of application scenarios.

[0023] As Figures 1 to 4 shown, the mold according to an embodiment of the present invention includes:

[0024] Moving template 1, on which a first placement groove 11 is provided;

[0025] Moving mold core 2, which is movably arranged in the first placement groove 11;

[0026] Oil cylinder 3, which is fixedly connected to the moving template 1, and its output end is connected to the moving mold core 2, and can drive the moving mold core 2 to reciprocate;

[0027] A pair of pressing strips 4, which are respectively arranged on both sides of the moving mold core 2 and are fixedly connected to the inner wall of the first placement groove 11;

[0028] A pair of guiding strips 5, which are arranged at the bottom of the first placement groove 11 and are slidably connected to the moving mold core 2, and the moving mold core 1 can slide along the guiding strips 5.

[0029] Furthermore, as Figures 1 to 2 shown, in this embodiment, a wear-resistant plate 6 is further provided at the bottom of the first placement groove 11.

[0030] Furthermore, as Figure 3 shown, in this embodiment, limiting steps 21 are provided on both sides of the moving mold core 2, and the limiting steps 21 are in sliding contact with the bottom of the pressing strip 4 and can slide relative to each other, and the pressing strip 4 plays a limiting role on the limiting steps 21.

[0031] Furthermore, asFigure 1 , 3 As shown in 3 , in this embodiment, a number of positioning grooves 22 are further provided on both sides of the moving die core 2, and a number of positioning protrusions 41 matching the positioning grooves 22 are also provided on the pressure strip 4. The positioning protrusions 41 are made of rubber and have the ability of elastic deformation, which plays an auxiliary positioning role for the moving die core 2.

[0032] Furthermore, as Figures 1 to 2 shown, in this embodiment, a guide groove 12 is further provided on the moving template 1, and the guide groove 12 communicates with the first placement groove 11.

[0033] Furthermore, as Figures 1 to 2 shown, in this embodiment, it further includes: a connecting block. The output end of the oil cylinder 3 is fixedly connected to the moving die core 2 through the connecting block, and the connecting block is coupled with the guide groove 12.

[0034] Furthermore, as Figure 1 shown, in this embodiment, a chamfer is provided on one side of the connecting block close to the guide groove 12.

[0035] Working principle:

[0036] (1) When the injection mold is closed for the first time, the front mold guide post 7 will be inserted into the rear mold guide sleeve 8 for positioning (prior art).

[0037] (2) When the injection mold is opened for the first time, the mold is normally opened, and no ejection action is performed after the opening action is completed.

[0038] (3) After the injection mold is opened for the first time, the oil cylinder 3 starts to act, and at the same time drives the moving die core 2 to move backward to the second injection position. At this time, the connecting block moves into the guide groove 12.

[0039] (4) When the injection mold is closed for the second time, the front mold guide post 7 will be inserted into the rear mold guide sleeve 8 for positioning.

[0040] (5) When the injection mold is opened for the second time, the mold is normally opened, and after the opening action is completed, the ejector pin starts to perform the ejection action to eject the product.

[0041] Above, with reference to Figures 1 to 4 the mold according to the embodiment of the present invention is described, which greatly reduces the mold cost, has a simple structure, and is relatively simple and fast to maintain.
