[0002] Some products require side openings for molding and are die-cast using liquid alloy. When the material is injected at high speed, the alloy material will quickly impact the molding cavity, causing the mold itself to be eroded, which greatly reduces the service life of the mold. In addition, side openings increase the number of mold parts and result in low demolding efficiency. Utility Model Content

[0003] One objective of this invention is to provide a mold for side-opening products with reduced flow rate, which reduces erosion inside the mold by using a flow channel with a bend, and the side slider seat facilitates demolding of products with forming holes.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A mold for a side-opening product with reduced flow rate includes an upper mold plate and a lower mold plate. An upper mold core is installed inside the upper mold plate, and a lower mold core is installed inside the lower mold plate. In-mold screws connect the upper mold plate and the upper mold core, and the lower mold plate and the lower mold core. A product forming cavity is formed between the upper mold core and the lower mold core. An inclined guide post is fixed on the upper mold plate.

[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 mold for a side-opening product with reduced flow rate includes an upper mold plate 1 and a lower mold plate 2. An upper mold core 3 is installed inside the upper mold plate 1, and a lower mold core 4 is installed inside the lower mold plate 2. Mold screws 5 are connected between the upper mold plate 1 and the upper mold core 3, and between the lower mold plate 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. An inclined guide post 6 is fixed on the upper mold plate 1. A slider seat 7 is provided on one side of the upper mold core 3. The lower end of the inclined guide post 6 passes through the slider seat 7 at an incline. The slider seat 7 is slidably connected to the inclined guide post 6. The slider seat 7 moves along the horizontal direction. A slider core 8 is fixed at the front end of the slider seat 7. The slider core 8 is inserted into the product forming cavity. A flow channel 9 is provided on one side of the lower mold core 4. At least one bend exists in the middle of the flow channel 9.

[0025] When the liquid is injected from top to bottom through the flow channel 9, the flow rate of the alloy liquid is buffered by the bending part, and the material is slowly filled into the product molding cavity, thereby die-casting. When demolding, the upper mold plate 1 drives the upper mold core 3 to rise. The rise of the inclined guide post 6 causes the relatively sliding slider seat 7 to move outward horizontally, pulling the slider core 8 away from the side opening of the product 24, and then the product 24 is separated from the lower mold core 4 of the lower mold plate 2.

[0026] A pressure strip 10 is installed on the lower template 2. The two sides of the slider seat 7 are slidably connected to the pressure strip 10. Under the action of the fixed pressure strip 10, the slider seat 7 moves horizontally, forcing the slider core 8 to detach from the product 24.

[0027] A wear-resistant plate 11 is fixed on the outer surface of the slider seat 7. The addition of the wear-resistant plate 11 effectively increases the number of uses and lifespan of the slider seat 7.

[0028] A slag bag 12 is connected to the outside of the product forming cavity, through which slag and gas are discharged to the outside.

[0029] A sprue sleeve 13 is provided on the upper mold plate 1. A flow divider cone 14 is connected to the lower end of the sprue sleeve 13. The flow divider cone 14 is connected to the runner 9. After the mold is closed, the material is poured from the sprue sleeve 13. The material enters through the flow divider cone 14 and the flow of the runner 9 guides the material into the product molding cavity and fixes it into the shape of the product 24.

[0030] A guide sleeve 15 is installed on the lower template 2, and a guide post 16 is fixed on the upper template 1. The guide post 16 slides on the guide sleeve 15 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 16 and the guide sleeve 15.

[0031] 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.

[0032] 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 4. 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 detached from the lower mold core 4. Support head 21 restricts the upward position of ejector plate 18.

[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.
