[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] An ejection mechanism for a die-casting mold of an L-shaped structure product, such as Figures 1-7 As shown, the mold includes a slider seat 1, a slider 2, a slider lever 3, a locking block 4, and at least one set of ejector components 5. The slider seat 1 is slidably mounted on the fixed mold, and the slider lever 3 and locking block 4 are mounted on the moving mold. The slider lever 3 drives the slider seat 1 to reciprocate. The slider 2 is mounted on the slider seat 1, and the ejector components 5 are mounted on the slider 2. By setting the ejector components 5, the mold supports the product during the mold opening process, allowing the product to separate from the mold and preventing product deformation.

[0018] The ejection assembly includes an ejector pin 51, a reset member 52, and an ejector post 53. An ejector pin hole is provided on the slider 1, and the ejector pin 51 is slidably connected to the ejector pin hole. The reset member 52 is mounted on the ejector pin 51, providing axial restoring force to the ejector pin 51. The ejector post 53 is slidably mounted on the slider seat 1, with one end of the ejector pin 51 contacting the ejector post 53, and the other end of the ejector post 53 acting on the locking block 4. During mold opening, the ejector pin 51 is supported on the locking block 4 by the ejector post 53, keeping it stationary at the beginning of the mold opening process. The slider 2 moves with the slider seat 1, causing the slider 2 to separate from the product. After the product separates, the ejection assembly 53 moves with the slider.

[0019] In one embodiment, such as Figures 1-7 As shown, the top post 53 includes a first limiting part 531 and a guide part 532, with the guide part 532 slidably connected to the slider seat 1. The first limiting part 531 restricts the initial position of the top post 53, causing the end of the ejector pin 51 to match the end face of the slider 2. The guide part 532 guides the top post 53 to move axially, thereby supporting the ejector pin 51.

[0020] In one embodiment, such as Figures 1-7 As shown, the end of the guide portion 532 is curved to reduce friction between the top post 53 and the locking block 4.

[0021] In one embodiment, such as Figures 1-7 As shown, the ejector assembly 5 also includes a guide sleeve 54, which is fixedly connected to the slider seat 1, and the ejector post 53 is slidably connected to the guide sleeve 54. The slider seat 1 is provided with an installation groove, and the guide sleeve 54 is fixedly installed in the installation groove. The end face of the guide sleeve 54 cooperates with the ejector post 53 to stop the ejector post 53; at the same time, it guides the ejector post 53 to move axially.

[0022] In one embodiment, such as Figures 1-7 As shown, the ejector pin 51 includes an ejector portion 511 and a second limiting portion 512. A reset member 52 acts on the slider 2 and the second limiting portion 512. The ejector portion 511 is slidably connected to the slider 2. The reset member 52 acts on the second limiting portion 512 to provide axial driving force to the ejector pin 51, causing the ejector pin 51 to act on the ejector post 53.

[0023] In one embodiment, such as Figures 1-7 As shown, the ejector pin 51 and the ejector post 53 are floatingly connected. In this embodiment, the ejector pin 51 is tightly attached to the ejector post 53 through the reset member 52, and the ejector pin 51 and the ejector post 53 can be adaptively adjusted in the vertical plane.

[0024] In one embodiment, such as Figures 1-7 As shown, the reset component 52 is a spring.

[0025] In one embodiment, such as Figures 1-7 As shown, the slider base 1 is provided with an obliquely arranged drive groove 11, and the slider lever 3 is provided with a drive rod 31 that cooperates with the drive groove 11. During mold closing, the left oblique surface of the drive rod 31 cooperates with the left oblique surface within the drive groove 11, causing the drive rod slider base 1 to move the slider 2 to the left. During mold opening, the right oblique surface of the drive rod 31 cooperates with the right oblique surface within the drive groove 11, causing the drive rod slider base 1 to move the slider 2 to the right. Preferably, two drive grooves 11 are provided on both sides of the slider base 1, and correspondingly, two slider levers 3 are provided. This provides a stable driving force for the slider base 1.

[0026] In one embodiment, such as Figures 1-7 As shown, a guide groove 41 is provided on the locking block 4, and the guide groove 41 is vertically arranged. The top post 53 is placed in the guide groove 41, and the top post 53 is guided to move vertically in the groove through the guide groove 41.

[0027] In one embodiment, such as Figures 1-7 As shown, a first locking slope 12 is provided on the slider seat 1, and a second locking slope 42 that cooperates with the first locking slope 12 is provided on the locking block 4. When the mold is closed, the second locking slope 42 is in close contact with the first locking slope 12, further ensuring that the slider 2 is closed in place.

[0028] When using this utility model, such as Figures 1-7 As shown, when the mold opens, the moving mold moves upward, driving the slider seat 11 via the slider block 3, which in turn moves the slider 2 to the right. The ejector pin 53 is blocked by the locking block 4, supporting the ejector pin 51 to remain stationary. The ejector pin 51 also supports the product, causing the slider 2 to separate from the product's surface. After the ejector pin 53 separates from the locking block 4, the ejector pin 51 moves to the right under the action of the reset member 52, causing the ejector pin 51 to separate from the product's surface until the first limiting part 531 of the ejector pin 53 contacts the guide sleeve 54 and stops. At this time, the ejector pin 51 and the slider 2 move synchronously.

[0029] When the mold is closed, the moving mold moves down, and the slider block 3 drives the slider seat 1 to move to the left. When the mold is closed, the second locking plane 42 of the locking block 4 is in close contact with the first locking plane 12 of the slider seat 1.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
