[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1 to 4As shown in this embodiment, a die-casting mold for an annular radiator includes an upper mold plate 1 and a lower mold plate 2. A lower mold core 3 is installed inside the lower mold plate 2, and an upper mold core 4 is installed inside the upper mold plate 1. Hydraulic cylinders 5 are installed on both sides of the outer edge of the lower mold plate 2. A slider seat 6 is connected to the driving end of the hydraulic cylinder 5. A slider core 7 is connected to the slider seat 6. There are product forming cavities between the slider core 7 and the upper mold core 4, and between the slider core 7 and the lower mold core 3. A slag bag 8 surrounds the outer edge of the slider core 7. An exhaust block 9 is installed on the lower mold plate 2.
[0024] After the upper mold plate 1 and the lower mold plate 2 are closed, the hydraulic cylinder 5 pushes the slider core 7 into the space between the upper mold core 4 and the lower mold core 3 through the slider seat 6, so that the product forming cavity is formed and the die-cast product 24 is formed. When demolding, the upper mold plate 1 opens first, and then the hydraulic cylinder 5 controls the slider seat 6 to move outward, pulling the slider core 7 away from the product 24. Then the product 24 can be detached from the lower mold core 3.
[0025] The upper mold plate 1 is provided with a sprue sleeve 10. The lower end of the sprue sleeve 10 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 10. The material is introduced into the product molding cavity through the runner and fixed to form the shape of the product 24.
[0026] A guide sleeve 11 is installed on the lower template 2, and a guide post 12 is fixed on the upper template 1. The guide post 12 slides on the guide sleeve 11 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 12 and the guide sleeve 11.
[0027] A cylinder bracket 13 is fixed to the outer side of the lower mold plate 2. A cylinder plate 14 is installed on the cylinder bracket 13. The cylinder 5 is fixed in the middle of the cylinder plate 14. A pressure strip 15 is fixed to the inner side of the cylinder bracket 13. The slider seat 6 slides on the pressure strip 15. When the cylinder 5 is at the telescopic drive end, it controls the slider seat 6 to move horizontally. The slider seat 6 moves along the pressure strip 15 on the cylinder bracket 13 to ensure that the product forming cavity between the upper mold core 4 and the lower mold core 3 is accurate.
[0028] A pressure plate 16 is fixed on the slider seat 6, which protects the movement of the slider seat 6 under the fixed structure of the pressure plate 16.
[0029] Water channels 17 are distributed in both the upper mold plate 1 and the lower mold plate 2. Cooling water is introduced into the outside of the mold through the water channels 17 to reduce the internal temperature of the mold and to form the product 24 for demolding more quickly.
[0030] Ejector plate 18 and ejector base plate 19 are installed below the lower mold plate 2. Ejector pins 20 are fixed on the ejector plate 18. The upper end of the ejector pins 20 is inserted into the lower mold core 3. Support head 21 is provided on the ejector plate 18. Square irons 22 are provided on both sides of the lower mold plate 2. The ejector plate 18 and ejector base plate 19 are located between the square irons 22. Base plate 23 is fixed below the square irons 22. When demolding, the ejector plate 18 and ejector base plate 19 push the ejector pins 20 upward, so that the product 24 is lifted and removed from the lower mold core 3. Support head 21 restricts the upward position of ejector plate 18.
[0031] 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.
