Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, and particularly relates to a die-casting mold for a motor reduction box cover plate. Background Art

[0002] The motor reduction box cover plate is integrally die-cast by aluminum liquid entering a die-casting mold; Patent No. CN202121271284.X discloses a die-casting mold for a motor reduction box cover plate, which has a simple structure, is convenient to install, facilitates mold closing and clamping, prolongs the service life of the mold, and reduces the labor intensity of workers; however, when the upper and lower mold frames drive the mold core to close the mold, it is easy for the upper and lower mold frames to rub against each other, and it is easy to be scratched and damaged due to this. For this reason, we propose a die-casting mold for a motor reduction box cover plate. Content of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a die-casting mold for a motor reduction box cover plate.

[0004] The technical solution adopted by the utility model to solve its technical problems is a die-casting mold for a motor reduction box cover plate, which includes an upper mold frame and a lower mold frame. Concave holes are formed on the opposite surfaces of the upper mold frame and the lower mold frame, and there are multiple groups of concave holes. Conical cylinders are assembled in the upper mold frame and located in the concave holes, and there are multiple groups of conical cylinders. A chassis is assembled in the lower mold frame and located in the concave holes, and there are multiple groups of chassis. A disk seat is slidably installed in the lower mold frame and is slidably connected to the concave holes, and a spring A is assembled between the disk seat and the chassis. One end of the disk seat close to the conical cylinder is integrally structured with a top block inserted into the conical cylinder.

[0005] A slider that abuts against the top block is slidably installed in the conical cylinder, and a spring B and a shock-absorbing cylinder are assembled between the slider and the conical cylinder, and the shock-absorbing cylinder is located inside the circumference of the spring B.

[0006] By adopting the above technical solution, in the process of manufacturing the motor reduction box cover plate by using the die-casting mold, when the upper mold frame and the lower mold frame are closed, the conical cylinders in the concave holes of the upper mold frame are convenient to be inserted into the concave holes in the lower mold frame. At the same time, the spring in the concave hole of the lower mold frame is convenient to assist in supporting the disk seat. When the disk seat abuts against the conical cylinder, it is convenient to buffer, and it can buffer the closing of the upper mold frame and the lower mold frame, so that the two can abut and close more stably, and it is convenient to stably manufacture the motor reduction box cover plate.

[0007] When the lower die holder and the lower die holder are clamped together, the ejector block at the top of the disc seat can be inserted into the conical cylinder in the concave hole inside the upper die holder. At the same time, the slider in the conical cylinder abuts against the ejector block, and the spring B in the conical cylinder cooperates with the shock absorber cylinder to facilitate providing elasticity for the slider, thereby buffering the ejector block, so as to improve the stability when the upper die holder and the lower die holder are clamped together, enabling the die-casting mold to manufacture the motor reduction box cover more stably.

[0008] Specifically, a vertical rod is integrally formed on one side of the chassis close to the disc seat, and a vertical tube that fits the vertical rod is assembled at one end of the disc seat close to the chassis.

[0009] By adopting the above technical solution, the vertical rod on the top of the chassis is slidably connected to the vertical tube at the bottom of the disc seat, which is convenient for auxiliary support of the disc seat, enabling the disc seat to slide and displace more stably and facilitating buffering.

[0010] Specifically, an adhesive seat is bonded to the side of the disc seat away from the chassis.

[0011] By adopting the above technical solution, the adhesive seat has a certain elasticity, which is convenient for buffering and protecting when the disc seat abuts against the conical seat, thereby reducing the situation of abrasion and damage caused by rubbing between the two.

[0012] Specifically, a ring tube located outside the spring A is assembled on the top surface of the chassis.

[0013] By adopting the above technical solution, the ring tube on the top of the chassis is convenient for providing a certain limiting performance for the operation of the spring A and enabling the spring A to operate more stably.

[0014] Specifically, two clamping blocks that fit the lower die holder are integrally formed on the outer wall surface of the upper die holder, and there are two sets of convex strips that are adapted to the clamping blocks integrally formed on the outer wall surface of the lower die holder. An I-shaped block that is bolted to the lower die holder is clamped between the convex strip and the clamping block.

[0015] By adopting the above technical solution, when the upper die holder and the lower die holder are clamped together, the clamping blocks on the outer periphery of the upper die holder can fit with the lower die holder. At the same time, it is convenient to clamp the I-shaped block between the clamping block and the convex strip on the outside of the lower die holder, so that the upper die holder and the lower die holder are fastened when clamped together and are convenient for disassembly and assembly.

[0026] During use, in the process of manufacturing the motor reduction box cover plate using the die-casting mold, when the upper mold frame 1 and the lower mold frame 2 are closed, the conical cylinder 4 in the concave hole 3 of the upper mold frame 1 is convenient for inserting with the concave hole 3 in the lower mold frame 2. At the same time, the spring in the concave hole 3 of the lower mold frame 2 is convenient for providing auxiliary support for the disk seat 6. When the disk seat 6 abuts against the conical cylinder 4, it is convenient for buffering and can buffer the closing of the upper mold frame 1 and the lower mold frame 2, so that the two can abut and close more stably, facilitating the stable manufacturing of the motor reduction box cover plate;

[0027] When the lower mold frame 2 and the lower mold frame 2 are closed, the ejector block 8 at the top of the disk seat 6 can be inserted into the conical cylinder 4 in the concave hole 3 inside the upper mold frame 1. At the same time, the slider 9 in the conical cylinder 4 abuts against the ejector block 8, and the spring B 10 and the shock-absorbing cylinder 11 in the conical cylinder 4 cooperate with each other to facilitate providing elasticity for the slider 9, thereby buffering the ejector block 8, thus improving the stability when the upper mold frame 1 and the lower mold frame 2 are closed, enabling the die-casting mold to manufacture the motor reduction box cover plate more stably.

[0028] Such as Figure 2 and Figure 3 As shown, a vertical rod 12 is integrally formed on one side of the chassis 5 close to the disk seat 6, and a vertical tube 13 fitted with the vertical rod 12 is assembled at one end of the disk seat 6 close to the chassis 5.

[0029] During use, the vertical rod 12 at the top of the chassis 5 is slidably connected to the vertical tube 13 at the bottom of the disk seat 6, facilitating providing auxiliary support for the disk seat 6, enabling the disk seat 6 to slide and displace more stably and facilitating buffering.

[0030] Such as Figure 2 and Figure 3 As shown, an adhesive seat 14 is bonded to the side of the disk seat 6 away from the chassis 5.

[0031] During use, the rubber seat 14 has a certain elasticity, facilitating buffering protection when the disc seat 6 and the conical seat are in mutual contact, thereby reducing the condition of abrasion damage caused by rubbing between the two.

[0032] As Figure 2 and Figure 3 shown, a ring tube 15 is assembled on the top surface of the chassis 5 and is located outside the spring A7.

[0033] During use, the ring tube 15 on the top of the chassis 5 facilitates providing a certain limiting performance for the operation of the spring A7 and enables the spring A7 to operate more stably.

Two convex strips 17 adapted to the clamping blocks 16 are integrally formed on the outer wall surface of the lower die frame 2, and there are two groups of the convex strips 17. An I-shaped block 18 bolted to the lower die frame 2 is clamped between the convex strip 17 and the clamping block 16.

[0035] During use, when the upper die frame 1 and the lower die frame 2 are mutually closed, the clamping blocks 16 on the outer periphery of the upper die frame 1 can fit with the lower die frame 2. At the same time, it is convenient to clamp the I-shaped block 18 between the clamping block 16 and the convex strip 17 on the outside of the lower die frame 2, making the upper die frame 1 and the lower die frame 2 tightly closed when they are closed, and facilitating disassembly and assembly.

During the process of manufacturing the motor reduction box cover plate using the die-casting mold, when the upper die frame 1 and the lower die frame 2 are mutually closed, the conical cylinder 4 in the concave hole 3 of the upper die frame 1 is convenient to be inserted into the concave hole 3 in the lower die frame 2. At the same time, the spring in the concave hole 3 of the lower die frame 2 is convenient to provide auxiliary support for the disc seat 6. When the disc seat 6 and the conical cylinder 4 are in mutual contact, it is convenient to perform buffering and can also buffer the closing of the upper die frame 1 and the lower die frame 2, enabling the two to mutually abut and close more stably, facilitating the stable manufacturing of the motor reduction box cover plate. At the same time, when the upper die frame 1 and the lower die frame 2 are mutually closed, the top block 8 on the top of the disc seat 6 can be inserted into the conical cylinder 4 in the internal concave hole 3 of the upper die frame 1. At the same time, the slider 9 in the conical cylinder 4 abuts against the top block 8, and the spring B10 and the shock-absorbing cylinder 11 in the conical cylinder 4 cooperate with each other, facilitating providing elasticity for the slider 9, thereby buffering the top block 8, thus improving the stability when the upper die frame 1 and the lower die frame 2 are mutually closed, enabling the die-casting mold to more stably manufacture the motor reduction box cover plate.
