[0026] In the utility model, after the product is injection molded in the molding cavity, when the mold is opened, the upper mold plate moves upward and the arc surface of the bottom of the product can be separated from the lower mold plate through the front large slider core pulling mechanism 5, thereby preventing the bottom of the product from being damaged during ejection. The tunnel-type inclined core pulling mechanism 7 can form drainage holes at the bottom of both sides of the product and can automatically pull the core when the mold is opened. After the mold is opened, the translation core pulling mechanism 4 and the rear large slider core pulling mechanism 6 can realize automatic core pulling at the rear side and left and right sides of the molding cavity.

[0027] Specifically, the front large slider core-pulling mechanism 5 includes a horizontally arranged front slider seat 8, the inner end of which has an arc-shaped surface 9 connected to the bottom of the front side of the molding cavity 3, and also includes a front core-pulling assembly connected to the front slider seat 8. The arc-shaped surface at the inner end of the front slider seat 8 is connected to the bottom of the product. When the mold is opened, the front core-pulling assembly can drive the front slider seat 8 to move horizontally away from the molding cavity so that the arc-shaped surface at the inner end of the front slider seat 8 can be separated from the bottom of the product. Therefore, when the conventional ejection mechanism is ejected, the vertical thrust on the bottom of the product can be reduced to prevent damage to the product.

[0028] Specifically, the front core-pulling assembly includes two front core-pulling sliders 10 fixed on the outside of the front slider seat 8, and two inclined No. 1 driving rods 11 are fixedly connected to the upper mold plate 1, and the No. 1 driving rod 11 is obliquely inserted into the front core-pulling slider 10 and slidably cooperates with the front core-pulling slider 10. When the mold is opened, the upper mold plate moves upward to drive the No. 1 driving rod to move vertically upward, and the No. 1 driving rod moves vertically upward to drive the front core-pulling slider to move horizontally outward, and the horizontal outward movement of the front core-pulling slider can drive the front slider seat 8 to move horizontally outward.

[0029] Preferably, a plurality of vertical guide rods 12 are fixedly connected to the bottom of the upper template 1, and the bottom of the vertical guide rods 12 vertically penetrates the front slider seat 8 and is inserted into the lower template 2. The front slider seat 8 is also provided with a horizontal slide groove 13 that slides with the vertical guide rods 12. When opening the mold, the vertical guide rods can limit and guide the upper template to prevent the upper template from deviating, and the horizontal slide groove can prevent the front slider seat from interfering with the vertical guide rods when translating.

[0030] Specifically, combined with Figure 1-Figure 3As shown, the rear large slider core-pulling mechanism 6 includes an inclined rear slider seat 14, the inner end of which is obliquely inserted into the rear side of the molding cavity 3, and the lower mold plate 2 is also provided with a support guide structure arranged at the bottom of the rear slider seat 14 and a rear core-pulling assembly connected to the outer end of the rear slider seat 14, the support guide structure includes a support seat 15 fixed on the lower mold plate 2, and the top of the support seat 15 has an inclined guide surface 16, and the rear core-pulling assembly includes two inclined No. 1 linear drivers 17, the output shaft end of the No. 1 linear driver 17 is connected to the outer side of the rear slider seat 14, and two support rods 18 are also fixedly connected to the rear side wall of the lower mold plate 2, and the bottom of the No. 1 linear driver 17 is supported on the support rods 18. The synchronous action of the two No. 1 linear drivers 17 can drive the rear slider seat 14 to move obliquely upward in the inclined direction so that the inner end of the rear slider seat is separated from the product, and the inclined guide surface 16 on the top of the support seat 15 can guide and support the rear slider seat.

[0031] Those skilled in the art should understand that the first linear drive 17 may be an oil cylinder, an air cylinder or a linear motor, etc.

[0032] Specifically, the tunnel-type inclined core-pulling mechanism 7 includes a translation slider 19 arranged at the bottom of the lower template 2 and a tunnel slider 20 inclinedly arranged in the lower template 2. The top of the tunnel slider 20 is connected to the bottom of the rear side of the molding cavity 3. The inner end inclined surface of the translation slider 19 is recessed inwardly and provided with a push-pull groove 21 with a T-shaped cross-section. The bottom end of the tunnel slider 20 is provided with a push-pull slider 22 with a T-shaped cross-section. The push-pull slider 22 is inserted into the push-pull groove 21 and slidably cooperates with the push-pull groove 21. A vertically arranged No. 2 drive rod 23 is fixedly connected to the upper template 1. The No. 2 drive rod 23 is inserted into the connecting hole at the outer end of the translation slider 19, and the bottom end of the No. 2 drive rod 23 has an inclined bending portion 24. The tunnel slider 20 is inserted into the bottom of the product to form a drainage hole at the bottom of the product. When the mold is opened, the upward movement of the upper template can drive the No. 2 driving rod 23 to move vertically upward. The vertical upward movement of the No. 2 driving rod 23 can drive the translation slider 19 to move horizontally outward through the bending portion. The horizontal outward movement of the translation slider can drive the tunnel slider to move obliquely downward through the cooperation of the push-pull slide groove and the push-pull slider to separate the tunnel slider from the drainage hole of the product.

[0033] Specifically, the translation core-pulling mechanism 4 includes a side core-pulling seat 25 that is slidably matched with the lower mold plate 2, and the side core-pulling seat 25 is connected to the side of the molding cavity 3. The lower mold plate 2 is also fixedly connected with a second linear driver 26 connected to the outer end of the side core-pulling seat 25. After the mold is opened, the second linear driver 26 can drive the side core-pulling seat 25 to move away from the molding cavity so that the side core-pulling seat 25 and the product are separated, thereby realizing automatic core pulling on the left and right sides of the molding cavity.

[0034] Those skilled in the art should understand that the second linear drive 26 can be an oil cylinder, an air cylinder or a linear motor, etc.

[0035] The working principle of the utility model is as follows: after the product is injection molded in the molding cavity, when the mold is opened, the upper mold plate moves upward to separate the arc surface of the bottom of the product from the lower mold plate through the front large slider core pulling mechanism 5, thereby preventing the bottom of the product from being damaged during ejection, and the tunnel-type inclined core pulling mechanism 7 can form drainage holes at the bottom of both sides of the product and can automatically pull the core when the mold is opened. After the mold is opened, the translation core pulling mechanism 4 and the rear large slider core pulling mechanism 6 can realize automatic core pulling at the rear side and left and right sides of the molding cavity;

[0036] The arc surface at the inner end of the front slider seat 8 is connected to the bottom of the product. When the mold is opened, the front core pulling assembly can drive the front slider seat 8 to move horizontally away from the molding cavity so that the arc surface at the inner end of the front slider seat 8 can be separated from the bottom of the product. Therefore, when the traditional ejection mechanism is ejected, the vertical thrust on the bottom of the product can be reduced to prevent product damage. When the mold is opened, the upper template moves upward to drive the No. 1 driving rod to move vertically upward, and the No. 1 driving rod moves vertically upward to drive the front core pulling slider to move horizontally outward. The front core pulling slider moves horizontally outward to drive the front slider seat 8 to move horizontally outward. When the mold is opened, the vertical guide rod can limit and guide the upper template to prevent the upper template from deflecting. The horizontal slide groove can prevent the front slider seat from interfering with the vertical guide rod when it moves horizontally.

[0037] The synchronous action of the two No. 1 linear drivers 17 can drive the rear slider seat 14 to move obliquely upward in the inclined direction so that the inner end of the rear slider seat can be separated from the product. The inclined guide surface 16 on the top of the support seat 15 can guide and support the rear slider seat. The tunnel slider 20 is inserted to the bottom of the product to form a drainage hole at the bottom of the product. When the mold is opened, the upward movement of the upper template can drive the No. 2 drive rod 23 to move vertically upward. The vertical upward movement of the No. 2 drive rod 23 can drive the translation slider 19 to move horizontally outward through the bending portion. The horizontal outward movement of the translation slider can drive the tunnel slider to move obliquely downward through the cooperation of the push-pull slide groove and the push-pull slider to separate the tunnel slider from the drainage hole of the product. After the mold is opened, the action of the No. 2 linear driver 26 can drive the side core pulling seat 25 to move away from the molding cavity to separate the side core pulling seat 25 from the product, thereby realizing automatic core pulling on the left and right sides of the molding cavity.
