Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

The embodiment of the present utility model relates to a mould, which is convenient for molding, as shown in Figure 1-4, including an upper mold base 1, a lower mold base 2 and a lower mold core 8, and an upper mold is installed on the upper end of the lower mold base 2 Base 1, between the upper mold base 1 and the lower mold base 2, an upper mold core 9 and a lower mold core 8 installed in a stacked manner are installed, and the upper mold base 1 and the lower mold base 2 are located between the upper mold core 9 and the lower mold core 8 are equipped with a core-pulling structure 5, the core-pulling structure 5 includes a slider seat 15 and a slider 16, and the slider seat 15 is slidably installed in the lower mold base 2. Slide block 15 is equipped with the slide block 16 that inserts mold cavity near one end of mold cavity, and described upper mold core 9, lower mold core 8 and four slide blocks 16 surround and form mold cavity, and described upper mold base 1 The front part is vertically installed with a sprue sleeve 6 communicating with the mold cavity, and the upper end of the slider seat 15 located in front of the upper mold core 9 and the lower mold core 8 is equipped with a splitter cone 13 matched with the sprue sleeve 6. There is an installation groove 21 in the middle of the upper end of the upper mold base 1, and a core-inlaid needle fixing plate 10 sliding up and down is installed in the installation groove 21, and several lower-end insertion molds are vertically installed in the core-inlaid needle fixing plate 10. The core insert pin 11 of the cavity, and the upper opening of the installation groove 21 is sealed by the cover plate 7 .

The four corners of the upper mold base 1 and the lower mold base 2 are equipped with guide sleeves and guide posts 17 that cooperate with each other.

Positioning blocks 18 are arranged symmetrically on both sides of the slider base 15 located in front of the diverter cone 13 , and positioning grooves 19 matching the positioning blocks 18 are opened at the lower end of the upper mold base 1 .

The mold feet 3 are symmetrically arranged on both sides of the lower end of the lower mold base 2, and a push plate 4 is installed between the lower parts of the two mold feet 3, and several upper ends are vertically installed on the push plate 4 to insert into the top of the mold cavity. pole 12.

Example

When it is necessary to produce the shell, first install the entire mold on the die-casting machine, and then carry out debugging. After the debugging is completed, the upper mold base 1 and the lower mold base 2, as well as the upper mold core 9 and the lower mold core 8 are first closed. The four slide blocks 16 are brought together with the upper mold core 9 and the lower mold core 8. After completion, the solution in the molten state is injected into the mold cavity. The solution enters the mold from the sprue sleeve 6 and is diverted by the splitter cone 13. The solution will Fill the mold cavity and keep the pressure in the mold through the die-casting machine. After the completion, the mold is opened, and the upper mold base 1 and the upper mold core 9 move up. When the upper mold base 1 and the upper mold core 9 just start to move up, the core The insert pin 11 remains still until the core insert pin fixing plate 10 contacts the bottom of the installation groove 21, and the core insert pin 11 will move up together with the upper mold base 1 and the upper mold core 9, delaying the movement of the core insert. The time when the insert needle 11 is separated from the product is convenient for forming the hole position of the product. Finally, the oil cylinder 14 controls the movement of the four core-pulling structures 5, so that the slider 16 is separated from the product. Inside out.

The practical diverter cone 13 is installed on the slider seat 15. When the mold is opened, the diverter cone 13 will move away from the product along with the slider seat 15, which can prevent the diverter cone 13 from interfering when the product is taken out. The structure 5 facilitates mold forming; the cooling pipeline 22 is in a spiral shape, which greatly improves the cooling effect at the gate, and can prolong the life of the mold during the die-casting process. The slider seat 15 is located on both sides of the front of the diverter cone 13 and is symmetrically provided with positioning blocks 18. After the mold is closed, the slider seat 15 moves in place, and the positioning block 18 is interlocked with the positioning groove 19 to ensure that the diverter cone 13 is in contact with the sprue sleeve 6. position remains unchanged.
