[0021] To make the structure and advantages of this utility model clearer, the structure of this utility model will be further described below with reference to the accompanying drawings.

[0022] In this embodiment, the vertical direction, horizontal direction, front end, and rear end are all relative position descriptions and do not limit the actual orientation of the product.

[0023] A fixed mold angled ejector structure, see [link / reference] Figure 1 As shown, the product has undercut positions on three sides. These undercut positions offer significant demolding resistance. (See attached diagram.) Figure 1 As shown, it includes a slider body 2, a slider seat 1, an inclined pin 4, and an inclined pin fixing seat 5.

[0024] The front end of the slider body 2 is provided with a cavity structure that matches the barb structure of the product 3. The rear end of the slider body 2 is fixedly connected to the slider seat 1 by bolts. The slider seat 1 is connected to a drive structure that can drive the slider body 2 to move away from or closer to the product 3.

[0025] A groove 21 is provided in the middle of the lower end of the slider body 2. An inclined pin 4 is slidably connected in the groove 21. An inclined pin fixing seat 5 is provided at the lower end of the inclined pin 4. The inclined pin fixing seat 5 is fixedly connected to the fixed template and can abut against the lower end of the inclined pin 4.

[0026] The thickness of the front end of the inclined pin 4 is greater than that of the rear end. Side wings 41 are provided on both sides of the inclined pin 4. The side wings 41 are structurally matched with the slide groove 21. The inclined pin 4 and the slider body 2 can slide relative to each other along the inclined direction of the side wings 41. As shown in the attached figure, the inclined direction forms an acute angle with the horizontal direction. The speed of the inclined pin moving laterally is greater than the lifting speed. After the slider body moves laterally a certain distance, the inclined pin can disengage from the inclined pin fixing seat 5 and then move with the slider body.

[0027] See appendix Figure 4 As shown, a first limiting protrusion 51 is provided at the rear of the upper end of the inclined pin fixing seat 5. The first limiting protrusion 51 is used to abut against the rear end of the inclined pin 4 to prevent the inclined pin 4 from moving backward. A second limiting protrusion is provided on both sides of the front of the upper end of the inclined pin fixing seat 5. A limiting groove 42 is provided in the middle of the side wings 41 on both sides of the inclined pin 4. The second limiting protrusion is embedded in the limiting groove 42 and can move within the range of the limiting groove 42. The length of the limiting groove 42 limits the movable range of the inclined pin 4.

[0028] See appendix Figure 5 , 6 As shown, the cross-section of the groove 21 is a T-shaped structure, which is matched with the inclined pin 4.

[0029] The operation of this structure is as follows:

[0030] The slider seat 1 drives the slider body 2 to move away from the product 3. At this time, the inclined pin fixing seat 5 abuts against the inclined pin 4. The inclined pin 4 cannot move. The front end of the inclined pin 4 presses against the side of the product 3, so that the inverted structure of the product 3 is separated from the slider body 2.

[0031] As the slider body 2 moves continuously, the slide groove 21 of the slider body 2 drives the inclined pin 4 to move upward until the rear end of the inclined pin 4 is freed from the restriction of the inclined pin fixing seat 5, and the inclined pin 4 moves backward and separates from the product 3.

[0032] The front end of the limiting groove 42 of the inclined pin 4 abuts against the second limiting protrusion of the inclined pin fixing seat 5, stopping the mold opening action.

[0033] The above merely illustrates the embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
