[0062] In this embodiment, the second convex block 542 is in the shape of a triangular prism, and an edge of the second convex block 542 is arranged at the upper part of the housing 544.

[0063] Please refer to Figure 2 , a first pin is penetrated through the housing 544 of the insert block 54, the first pin is fixed on the first ejector plate 51, a second pin is penetrated through the fifth through hole 543 of the body 541 of the insert block 54, and the second pin is fixed on the first ejector plate 51.

[0064] When the compact retractable slider 53 mechanism is in the injection molding state, the lower end of the body 541 of the insert block 54 can be placed on the upper end of the first cylinder.

[0065] The fixed mold plate 6 is arranged above the movable mold plate 4.

[0066] Please refer to Figure 3 , an inclined guide post 61 is provided on the fixed mold plate 6, the inclined guide post 61 faces the slider 53, a part of the inclined guide post 61 is penetrated through the slider 53, the inclined guide post 61 is inclined towards the moving direction of the slider 53, two inclined guide posts 61 are provided on one slider 53, the inclined guide posts 61 on the two sliders 53 are arranged oppositely, and the inclined guide posts 61 arranged on the two sliders 53 are wider at the positions closer to the distance between the sliders 53.

[0067] Please refer to Figure 2, the third fixed plate 7 is arranged on the side of the fixed template 6 relatively far from the moving template 4.

[0068] Please refer to Figure 3 , a fifth guide post 71 is vertically provided on the third fixed plate 7, and the third fixed plate 7 and the fixed template 6 are sleeved on the fifth guide post 71.

[0069] Please refer to Figure 3 , a sixth guide sleeve is arranged in the fixed template 6, a sixth guide post 55 is arranged in the moving template 4, and a part of the sixth guide post 55 is sleeved in the sixth guide sleeve. The moving template 4 and the fixed template 6 perform opening and closing movements through the sixth guide sleeve and the sixth guide post 55.

[0070] Please refer to Figure 4 , a plurality of fifth grooves 532 are arranged on the slider 53, and the surfaces of the two sliders 53 provided with the fifth grooves 532 are arranged opposite to each other.

[0071] With the above structure, please refer to Figure 2 , injection liquid is injected into the compact retractable slider 53 mechanism through the pouring port on it, and the injection liquid gathers and cools outside the shell 544 of the insert 54 inside the moving template 4 to form the product 8.

[0072] It can be understood that grooves are formed inside the product 8 through the third convex blocks 545 outside the shell 544, and the product 8 cannot be directly removed from the shell 544.

[0073] At this time, the ejector rod is used to push the ejector pin plate 2 upward from the ejector pin hole 11 of the bottom plate 1. The ejector pin plate 2 moves upward, and the limiting block 23 rotates a certain angle around the rotating shaft. At this time, the ejector pin plate 2 can drive the secondary ejector pin plate 3 to move upward together. The ejector pin plate 2 pushes the upper first push plate 51 out of the third groove 43 of the moving template 4 through the second guide post 21, and the secondary ejector pin plate 3 pushes the second push plate 52 to move upward in the first groove 41 through the third guide post 31.

[0074] When the limiting block 23 rotates to one end abutting against the lower part of the secondary ejector pin plate 3 and the other end abutting against the bottom plate 1, the ejector pin plate 2 continues to move upward. Under the action of the limiting block 23, the secondary ejector pin plate 3 accelerates upward relative to the ejector pin plate 2.

[0075] At this time, the first push plate 51 and the second push plate 52 start to separate, and the upward movement speed of the second push plate 52 is faster than that of the first push plate 51. The housing 544 of the insert block 54 is fixed to the first push plate 51 through a first pin, and the housing 544 is consistent with the first push plate 51. A second pin is inserted into the fifth through hole 543 of the main body of the insert block 54, and the second pin can move within the fifth through hole 543. The main body of the insert block 54 can remain stationary when the housing 544 of the insert block 54 moves upward and is disengaged from the housing 544, so that the inside of the housing 544 is in a hollow state.

[0076] Furthermore, the second push plate 52 moves upward relative to the first push plate 51 at a relatively fast speed, and the second push plate 52 moves upward relative to the housing 544 of the insert block 54.

[0077] Please refer to Figure 6 and Figure 5 , Further, the fourth convex block 546 originally in the fourth groove 522 of the second push plate 52 moves into the fourth through hole 521 of the second push plate , the inner wall of the fourth through hole 521 squeezes the fourth convex blocks 546 on the front and back of the housing 544, the front and back of the housing 544 shrink inward, and the third convex block 545 on the housing 544 disengages from the groove inside the product 8, so that the product 8 is disengaged from the housing 544.

[0078] Please refer to Figure 3 , when the ejector rod pushes the ejector plate 2 upward, the bottom plate 1, the square iron 12 and the moving template 4 are moved downward, and the moving template 4 starts to separate from the fixed template 6. At the same time, the slider 53 on the moving template 4 separates along the length direction of the second groove 42 under the action of the inclined guide post 61, so that the third groove 43 of the moving template 4 is exposed. When the product 8 is disengaged from the housing 544, the housing 544 can fall out between the two sliders 53 and between the moving template 4 and the fixed template 6.

[0079] In the present invention, specific embodiments are used to elaborate the principles and implementation manners of the present invention. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
