[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown in this embodiment, a tilted core-pulling mold includes an upper template 1 and a lower template 2. An upper mold core 3 is installed inside the upper template 1, and a lower mold core 4 is installed inside the lower template 2. Mold screws 5 are connected between the upper template 1 and the upper mold core 3, and between the lower template 2 and the lower mold core 4. A product forming cavity is formed between the upper mold core 3 and the lower mold core 4. A hydraulic cylinder 6 is installed on the outside of the lower template 2. A slider guide seat 7 is connected to the driving end of the hydraulic cylinder 6. An inclined slide groove 8 is provided on the slider guide seat 7. An inclined slider core 9 is slidably connected to the inclined slide groove 8. The upper end of the inclined slider core 9 is inserted into the product forming cavity.

[0025] After the upper mold plate 1 and the lower mold plate 2 are closed, the upper mold core 3 and the lower mold core 4 form the product forming cavity. After the die-casting material is in the product forming cavity, the driving end of the hydraulic cylinder 6 extends to its longest length, and the slider guide seat 7 is inserted into the lower mold plate 2. Under the action of the inclined slide 8, the inclined slider core 9 pushes into the product forming cavity at a certain angle, so that the product 25 can be die-cast completely. Then, when demolding, the upper mold plate 1 drives the upper mold core 3 to rise, opening the product forming cavity. The hydraulic cylinder 6 controls the slider guide seat 7 to retract, and the inclined slider core 9 slides down obliquely with the inclined slide 8, so that the product 25 can be demolded and taken out.

[0026] A cylinder bracket 10 is fixed to the outside of the lower template 2. A cylinder plate 11 is installed on the cylinder bracket 10. The fixed end of the cylinder 6 is locked in the middle of the cylinder plate 11. A cylinder connecting rod 12 is connected between the driving end of the cylinder 6 and the slider guide seat 7. The cylinder 6 is fixed on the cylinder plate 11 of the cylinder bracket 10. The cylinder connecting rod 12 drives the slider guide seat 7 to move horizontally.

[0027] A slag bag 13 is connected to the outside of the product molding cavity. The slag bag 13 discharges the gas outward together, reducing porosity.

[0028] The lower template 2 has a threaded connection to a lifting ring 14. Since the mold as a whole has a certain weight, the lifting ring 14 is used to facilitate the movement of the robot arm.

[0029] The upper mold plate 1 is provided with a sprue sleeve 15. The lower end of the sprue sleeve 15 extends into a runner. The runner connects to the product molding cavity. After the mold is closed, the material is poured from the sprue sleeve 15. The material is guided into the product molding cavity through the runner and fixed to form the shape of the product 25.

[0030] A guide sleeve 16 is installed on the lower template 2, and a guide post 17 is fixed on the upper template 1. The guide post 17 slides on the guide sleeve 16 in the vertical direction. When the upper template 1 and the lower template 2 are closed and opened, they are guided to move up and down by the guide post 17 and the guide sleeve 16.

[0031] Water channels 18 are distributed in both the upper mold 1 and the lower mold 2. Cooling water is introduced into the outside of the mold through the water channels 18 to reduce the internal temperature of the mold and to form the product 25 for demolding more quickly.

[0032] Ejector plate 19 and ejector base plate 20 are installed below the lower mold plate 2. Ejector pin 21 is fixed on ejector plate 19. The upper end of ejector pin 21 is inserted into the lower mold core 4. Support head 22 is provided on ejector plate 19. Square iron 23 is provided on both sides of the lower mold plate 2. Ejector plate 19 and ejector base plate 20 are located between square iron 23. Base plate 24 is fixed below square iron 23. When demolding, ejector plate 19 and ejector base plate 20 push ejector pin 21 upward, so that product 25 is lifted and removed from the lower mold core 4. Support head 22 restricts the upward position of ejector plate 19.

[0033] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
