Detailed Embodiment

[0018] To further elaborate on the technical means and effects adopted by the present invention, the following describes in detail the embodiments of the present invention and their accompanying drawings.

[0019] The present invention provides a slider and inclined pin ejection structure, which is arranged on the male template and includes:

[0020] A slider 100, one end close to the product 200 is shaped to fit the undercut 210 of the product 200. The slider 100 is provided with inclined holes 101 on the side close to the product 200. In this embodiment, there are two groups of inclined holes 101 in different directions, which are respectively arranged corresponding to the inclined pins 110. The side of the slider 100 away from the product 200 is fixed to the moving end 131 of the driving member 130, and it moves on the male template under the action of the driving member 130. The slider 100 is provided with clearance holes 102 according to the position of the guide block 120, which are used to avoid the guide block 120 when the slider 100 moves;

[0021] The lifter pin 110. In this embodiment, a set of lifter pins 110 are respectively provided at both ends of the undercut 210 of the product 200. They are arranged in two sets of inclined holes 101 of the slider 100. When the slider 100 moves, the lifter pins 110 are actuated to move within the inclined holes 101 due to the effect of the inclined holes 101. One end of the lifter pin 110 close to the product 200 is shaped to conform to the undercut 210 of the product 200. It is movably arranged in the inclined hole 101 of the slider 100. A rotating member 111 is provided at the end away from the product 200. The lifter pin 110 is movably arranged in the guide groove 121 of the guide block 120 through the rotating member 111. In this embodiment, the rotating member 111 includes but is not limited to a rotating shaft;

[0022] The guide block 120 is fixed on the male mold plate. A guide groove 121 is provided therein. The guide groove 121 includes a first guide groove 122 and a second guide groove 123. When the lifter pin 110 moves under the action of the inclined hole 101 of the slider 100, first, the rotating member 111 drives the lifter pin 110 to move horizontally relative to the undercut 210 of the product 200 along the first guide groove 122 until it exits the undercut 210 of the product 200. Then, the rotating member 111 drives the lifter pin 110 to move vertically relative to the undercut 210 of the product 200 along the second guide groove 123 until it is far away from the undercut 210 of the product 200. In addition to limiting the distances of the lifter pin 110 in two displacement directions, the first guide groove 122 and the second guide groove 123 also limit the sequence of the movement directions of the lifter pin 110, ensuring that during the core-pulling process, the lifter pin 110 moves in the first direction first, and only after the glue surface of the lifter pin 110 completely exits the undercut 210 of the product 200, will it move in the second direction;

[0023] The driving member 130 is fixed on the male mold plate. The moving end 131 of the driving member 130 is fixedly connected to the end of the slider 100 away from the product 200. In the embodiment, the moving end 131 of the driving member 130 includes but is not limited to a live rod.

[0024] The working process of the present invention is as follows: After the product 200 is formed, the slider 100 moves towards one end away from the product 200 under the action of the moving end 131 of the driving member 130. At the same time, under the action of the inclined hole 101 of the slider 100, the inclined pin 110 first drives the inclined pin 110 to move horizontally relative to the undercut 210 of the product 200 through the rotating member 111 at one end thereof until it exits the undercut 210 of the product 200. At this time, the rotating member 111 is at the end of the first guide groove 122 and enters the initial end of the second guide groove 123. Subsequently, the slider 100 continues to move towards one end away from the product 200 under the action of the moving end 131 of the driving member 130, and the transmission member 111 drives the inclined pin 110 to move vertically relative to the undercut 210 of the product 200 until it is away from the undercut 210 of the product 200. Until it moves to the limit position of the second guide groove 123, that is, the end of the second guide groove 123, the slider 100 and the inclined pin 110 stop moving. At this time, the slider 100 and the inclined pin 110 completely exit the undercut 210 of the product 200.

[0025] The beneficial effect of the present invention is that the present invention adopts a slider inclined pin ejection structure, which uses the moving end 131 of the driving member 130 to drive the slider 100 to move, and then makes the inclined pin 110 drive the inclined pin 110 to move along the guide groove 121 through the rotating member 111 at one end under the action of the inclined hole 101 of the slider 100 until it exits the undercut 210 of the product 200. This structure can be used for products with undercut structures in two directions, and this structure can simplify the mold structure, and it is easy to process, convenient to install, and has low cost.

[0026] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made by any person skilled in the art based on the technical solution of the present invention to the above embodiments all fall within the protection scope of the present invention.
