Technical Field

[0001] This utility model relates to the field of pickup truck clutch technology, and in particular to a die-casting mold for producing the front housing of a pickup truck clutch. Background Technology

[0002] Pickup trucks are a very practical and common mode of transportation. They can be used as special-purpose vehicles, multi-purpose vehicles, official vehicles, commercial vehicles, or as family vehicles for cargo transport, tourism, and rental purposes.

[0003] The pickup truck clutch is an important component of a pickup truck. The pickup truck clutch includes parts such as the front clutch housing, etc. Figure 6 As shown, the front housing of a pickup truck clutch includes a front housing body 23, which has two inner cavities 24, front and rear. Ribs 25 are arranged on the sides of the front housing body 23. A docking post 26 is provided at the lower part of the front inner cavity 24. The end of the docking post 26 is provided with a connecting hole 27. The structure of the front housing of the pickup truck clutch is complex and relatively difficult to form. Moreover, due to the relatively large volume of the front housing body 23, in order to speed up the injection of molten metal into the mold cavity, the flow channel is designed to be wide and short. When the mold is opened, the material strip at the flow channel is easily pulled to the upper mold by the material barrel, causing the product to tear. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a die-casting mold for producing the front housing of a pickup truck clutch. A cold material groove is added to the side wall of the flow cone. The cold material groove generates a certain pulling force to pull the material cake down, so as to avoid the material strip at the flow channel being pulled to the upper mold by the material cylinder and causing the product to tear.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a die-casting mold for producing the front housing of a pickup truck clutch is provided, including an upper mold frame and a lower mold frame. An upper mold core and a lower mold core are stacked between the upper mold frame and the lower mold frame. A mold cavity is provided between the upper mold core and the lower mold core. A front insert and a rear insert are respectively installed on the front and rear sides of the upper end of the lower mold core and inserted into the mold cavity. The front insert and the rear insert are connected together. A left insert and a right insert are respectively installed on the left and right sides of the upper end of the lower mold core and inserted into the mold cavity. A flow divider cone is installed on the upper end of the left insert. A cold material groove is opened on the right side of the middle part of the flow divider cone. The width and height of the cold material groove gradually increase from left to right. A material cylinder is installed inside the upper part of the upper mold frame and sleeved outside the flow divider cone. A flow channel is provided at the lower end of the upper mold core between the material cylinder and the mold cavity. The front insert, the rear insert, the left insert, and the right insert are all equipped with independent core-pulling power devices.

[0006] As a supplement to the technical solution described in this utility model, the core-pulling power device includes a slider seat and a core-pulling cylinder. A slider seat is slidably installed on the upper end of the lower mold frame at the front, back, left, and right sides of the lower mold core. One end of the four slider seats is respectively connected to the front insert, the rear insert, the left insert, and the right insert. A core-pulling cylinder is fixedly installed on the front, back, left, and right sides of the lower mold frame, and the core-pulling cylinder is connected to the corresponding slider seat.

[0007] As a supplement to the technical solution described in this utility model, the two slider seats located on the front and rear sides are provided with multiple oblique pulling slots arranged side by side on their upper ends, and the lower end of the upper mold frame is provided with an oblique pulling block that is inserted into the oblique pulling slot.

[0008] As a supplement to the technical solution described in this utility model, a hole rod is horizontally inserted from front to back into the lower part of the slider seat located on the front side. One end of the hole rod is inserted into the mold cavity, and a stop block is vertically inserted into the upper end of the slider seat on the front side, which abuts against the other end of the hole rod.

[0009] As a supplement to the technical solution described in this utility model, a mold foot is installed on each side of the lower end of the lower mold frame, and a top plate assembly is provided between the two mold feet. The top plate assembly is provided with multiple push rods for inserting into the cavity.

[0010] As a supplement to the technical solution described in this utility model, the left side of the right insert is provided with a rib forming part.

[0011] Beneficial effects: This utility model relates to a die-casting mold for producing the front housing of a pickup truck clutch. A cold slug groove is added to the side wall of the flow cone. The cold slug groove generates a certain pulling force to pull the material cake downward, preventing the material strip at the flow channel from being pulled to the upper mold by the material cylinder and causing the product to tear. The width and height of the cold slug groove gradually increase from left to right, which is designed to facilitate side demolding. When the upper and lower molds are separated, the sliding blocks on both sides, along with the front and rear inserts, are separated from the formed product through the cooperation structure of the inclined pull block and the inclined pull groove. The subsequent core-pulling cylinder only needs a small force to continue sliding the front and rear inserts outward, which can effectively reduce the specifications of the two core-pulling cylinders and effectively reduce the mold cost. One end of the hole rod is used to form the connecting hole at the end of the mating post. The hole rod is a consumable part. When the hole rod needs to be replaced, the stop block is removed from the upper end of the sliding block, and the protruding part of the hole rod is squeezed to remove the hole rod from the lower part of the sliding block. The operation is convenient. Attached Figure Description

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] The present invention relates to a die-casting mold for producing the front clutch housing of a pickup truck, such as... Figure 1-6As shown, the device includes an upper mold frame 1 and a lower mold frame 4. An upper mold core 2 and a lower mold core 3, stacked vertically, are installed between the upper mold frame 1 and the lower mold frame 4. A mold cavity is provided between the upper mold core 2 and the lower mold core 3. A front insert 5 and a rear insert 16, inserted into the mold cavity, are respectively installed on the front and rear sides of the upper end of the lower mold core 3. The front insert 5 and the rear insert 16 are joined together. A left insert 6 and a right insert 7, inserted into the mold cavity, are respectively installed on the left and right sides of the upper end of the lower mold core 3. The upper end of the left insert 6 is equipped with... There is a flow divider cone 8, and a cold sluice 9 is opened on the right side of the middle part of the flow divider cone 8. The width and height of the cold sluice 9 gradually increase from left to right. A material cylinder 10 is installed inside the upper part of the upper mold frame 1 and sleeved outside the flow divider cone 8. The lower end of the upper mold core 2 is provided with a flow channel 19 between the material cylinder 10 and the mold cavity. The front insert 5, the rear insert 16, the left insert 6 and the right insert 7 are all equipped with independent core pulling power devices. The left side of the right insert 7 is provided with a rib forming part 22.

[0021] The core-pulling power device includes a slider seat 11 and a core-pulling cylinder 12. A slider seat 11 is slidably installed on the upper end of the lower mold frame 4, located at the front, back, left and right sides of the lower mold core 3. One end of the four slider seats 11 is respectively connected to the front insert 5, the rear insert 16, the left insert 6 and the right insert 7. A core-pulling cylinder 12 is fixedly installed on the front, back, left and right sides of the lower mold frame 4. The core-pulling cylinder 12 is connected to the corresponding slider seat 11.

[0022] The two slider seats 11 located on the front and rear sides each have multiple oblique pull slots 17 arranged side by side on their upper ends. The lower end of the upper mold frame 1 is provided with an oblique pull block 18 that is inserted into the oblique pull slot 17. When the upper mold and the lower mold are separated, the slider seats 11 on the front and rear sides, along with the front insert 5 and the rear insert 16, are separated from the molded product through the cooperation structure of the oblique pull block 18 and the oblique pull slot 17. The subsequent core-pulling cylinder 12 only needs a small force to continue to slide the front insert 5 and the rear insert 16 outward, which can effectively reduce the specifications of the two core-pulling cylinders 12 and effectively reduce the mold cost.

[0023] The front slider seat 11 has a hole rod 20 horizontally inserted from front to back at its lower part. One end of the hole rod 20 is inserted into the mold cavity. The upper end of the front slider seat 11 has a stop block 21 vertically inserted, which holds the other end of the hole rod 20. The stop block 21 and the slider seat 11 can be designed with fasteners to prevent the stop block 21 from falling out. One end of the hole rod 20 is used to form the connecting hole 27 at the end of the mating post 26. The hole rod 20 is a consumable part and needs to be replaced frequently. When the hole rod 20 needs to be replaced, the stop block 21 is removed from the upper end of the slider seat 11, and the protruding part of the hole rod 20 is squeezed to remove the hole rod 20 from the lower part of the slider seat 11. The operation is convenient.

[0024] The lower mold frame 4 has a mold foot 15 installed on each side of its lower end, and a top plate assembly 14 is provided between the two mold feet 15. The top plate assembly 14 is provided with a plurality of ejector rods 13 for inserting into the cavity.

[0025] When producing the front clutch housing for a pickup truck, the upper mold frame 1 and upper mold core 2 are controlled to close with the lower mold frame 4 and lower mold core 3. The front insert 5 and rear insert 16 are joined together. The front insert 5 and rear insert 16 are used to assist in forming the front and rear inner cavities 24, respectively. The left insert 6 and right insert 7 assist in forming the outer contour of the front housing body 23. The rib forming part 22 on the left side of the right insert 7 is used to assist in forming the ribs 25 on the side of the front housing body 23. One end of the hole rod 20 is used to form the connecting hole 27 at the end of the docking post 26. Then, the molten metal enters the mold from the barrel 10 and fills the mold cavity through the diversion cone 8. The mold is then pressurized by the die casting machine. After the product is formed, then... When the mold is opened, the upper mold frame 1 and the upper mold core 2 move upward. Due to the addition of a cold slug groove 9 on the side wall of the flow divider cone 8, the cold slug groove 9 generates a certain pulling force to pull the material cake downward, preventing the material strip at the flow channel from being pulled to the upper mold by the material cylinder 10 and causing the product to tear. The width and height of the cold slug groove 9 gradually increase from left to right. This design is to facilitate side demolding. When the mold is opened, through the cooperation structure of the inclined pull block 18 and the inclined pull groove 17, the slider seats 11 on the front and rear sides, along with the front insert 5 and the rear insert 16, are separated from the molded product. Then, the four core-pulling cylinders 12 control the front insert 5, the rear insert 16, the left insert 6, and the right insert 7 to move outward. Finally, the top plate assembly 14 controls the ejector rod 13 to eject the product.
