Description

Technical Field

[0001] This utility model relates to the technical field of automotive rubber product manufacturing equipment, specifically a new type of mold for producing automotive shock absorber blocks. Background Technology

[0002] Currently, the production of automotive shock absorbers mostly adopts a two-piece mold structure. Although this structure is simple, the mold is usually designed as a cuboid, which is large in size and heavy in weight. This results in long preheating time, unstable temperature control, and inconvenience in handling during operation, thus affecting production efficiency.

[0003] To address the aforementioned issues, this invention provides a novel mold with a reasonable structure, rapid preheating, and convenient operation, thereby improving the production efficiency and quality stability of automotive shock absorbers. Utility Model Content

[0004] The purpose of this invention is to provide a new type of mold for producing automotive shock absorbers, in order to solve the problems of long preheating time, inconvenient operation, and low production efficiency of existing molds.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel mold for producing automotive shock absorber blocks, comprising an upper mold cover, a middle mold core, a lower mold base plate, an upper mold positioning hole, a middle mold sleeve, and a lower mold positioning ring; the lower mold base plate is a circular plate structure with a lower mold positioning ring at its center, the lower mold positioning ring being integrally formed concentrically with the lower mold base plate; the middle mold sleeve is an annular cylindrical structure, its inner diameter matching the outer diameter of the lower mold positioning ring, and can be fitted onto the outside of the lower mold positioning ring; the middle mold core is a cylindrical structure, its lower end being concentrically and perpendicularly connected to the lower mold positioning ring, forming a T-shaped structure; the upper mold cover is a circular cover plate with an upper mold positioning hole at its center, the inner diameter of which matches the outer diameter of the middle mold core; the outer diameters of the upper mold cover and the lower mold base plate are the same, and both are larger than the outer diameter of the middle mold sleeve.

[0006] Preferably, the upper mold cover, middle mold core, lower mold base plate, middle mold sleeve, and lower mold positioning ring are all made of 45 steel.

[0007] Preferably, the height of the middle mold core is greater than the height of the middle mold sleeve, so that the upper end of the middle mold core is higher than the top surface of the middle mold sleeve by a certain distance, for cooperating with the positioning hole of the upper mold.

[0008] Preferably, the height of the intermediate mold core is 75mm, the height of the intermediate mold sleeve is 70mm, and the intermediate mold core is 15mm higher than the top surface of the intermediate mold sleeve.

[0009] Preferably, the outer diameter of the upper mold cover is 120mm and the thickness is 20mm; the outer diameter of the middle mold sleeve is 90mm, the inner diameter is 60mm and the height is 70mm; and the outer diameter of the lower mold base plate is 120mm and the height is 15mm.

[0010] The working process of this utility model is as follows: First, the middle mold sleeve is fitted onto the lower mold positioning ring, which is fixed in the center of the lower mold base plate, to form an annular cavity. Then, a measured amount of rubber raw material is filled into the cavity and placed around the middle mold core. Next, the upper mold cover is aligned and fitted with the upper end of the middle mold core through its central positioning hole to complete the mold closing. The entire mold is placed in a flat vulcanizing machine for heating and pressurizing vulcanization. After molding, taking advantage of the structural feature that the upper and lower molds are larger than the middle mold sleeve, the mold can be quickly opened by gently tapping the edge of the lower mold with a tool. Finally, the finished product is ejected from the mold sleeve, completing the efficient production of the shock absorber block.

[0011] The beneficial effects of this utility model are as follows: (1) This utility model adopts a separate joint structure of upper mold cover, middle mold sleeve and lower mold base plate. Compared with the traditional integral mold, its heat capacity is significantly reduced and the preheating time can be shortened from 1 hour to 30 minutes, which greatly improves the heat energy utilization efficiency and reduces production energy consumption. The sliding fit design of the middle mold sleeve and the lower mold positioning ring, combined with the precise alignment of the upper mold cover with the middle mold core through the positioning hole, makes the mold picking and positioning operation in the vulcanizing machine more convenient and smooth, effectively reducing the labor intensity of workers and shortening the operation interval.

[0012] (2) In this utility model, the dimensions of the upper and lower mold covers are larger than those of the middle mold sleeve, forming a natural operating flange. When opening the mold, the mold can be separated without damage by simply tapping the edge of the lower mold base plate with a simple tool. This greatly simplifies the demolding process, avoids the problem of difficult disassembly and easy damage of traditional molds, and improves production continuity and operational safety.

[0013] (3) This utility model ensures the centering and dimensional stability of the cavity by integrating the middle mold core and the lower mold positioning ring through concentric processing. The resulting shock absorber block has a dense and uniform internal structure, high dimensional accuracy, and significantly improved performance consistency. At the same time, the modular structure facilitates local repair or replacement, reducing maintenance costs during long-term use. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] like Figures 1 to 3 As shown, the mold of this utility model includes an upper mold cover 1, a middle mold core 2, a lower mold base plate 3, an upper mold positioning hole 4, a middle mold sleeve 5, and a lower mold positioning ring 6.

[0017] The lower mold base plate 3 is a circular steel plate with a diameter of 120mm and a height of 15mm. A cylindrical lower mold positioning ring 6 with a diameter of 60mm and a height of 10mm is provided in the center. The two are concentrically machined as one piece.

[0018] The middle mold sleeve 5 is an annular steel sleeve with an outer diameter of 90mm, an inner diameter of 60mm, and a height of 70mm. Its inner diameter is consistent with the outer diameter of the lower mold positioning ring 6, and it can be tightly fitted onto the outside of the lower mold.

[0019] The middle mold core 2 is a cylindrical steel core with a diameter of 16mm and a height of 75mm. Its lower end is concentrically and vertically connected to the lower mold positioning ring 6 to form a T-shaped structure.

[0020] The upper mold cover 1 is a circular steel plate with a diameter of 120mm and a thickness of 20mm. It has an upper mold positioning hole 4 with a diameter of 16mm in the center, which is used to cooperate with the upper end of the middle mold core 2.

[0021] In use, first put the middle mold sleeve 5 into the lower mold positioning ring 6, then place the rubber raw material around the middle mold core 2, and finally put the upper mold cover 1 onto the middle mold core 2 through the upper mold positioning hole 4, and put the whole into the flat vulcanizing machine for vulcanization.

[0022] During demolding, since the outer diameter of the upper and lower molds is larger than that of the middle mold sleeve, a copper rod can be used to tap the edge of the lower mold base plate to easily separate the upper and lower molds, and finally the product can be taken out from the middle mold sleeve.

[0023] The working process of this utility model is as follows: First, the middle mold sleeve 5 is fitted onto the lower mold positioning ring 6, which is fixed in the center of the lower mold base plate 3, to form an annular cavity. Then, a certain amount of rubber raw material is filled into the cavity and placed around the middle mold core 2. Next, the upper mold cover 1 is aligned and fitted with the upper end of the middle mold core 2 through its central upper mold positioning hole 4 to complete the mold closing. The entire mold is placed in a flat vulcanizing machine for heating and pressure vulcanization. After molding, taking advantage of the structural feature that the upper mold cover 1 and the lower mold base plate 3 are larger than the middle mold sleeve 5, the mold can be quickly opened by tapping the edge of the lower mold with a tool. Finally, the finished product is ejected from the mold sleeve, completing the efficient production of the shock absorber block.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, based on the technical teachings provided by this utility model and as common knowledge in the mechanical field, other equivalent modifications and improvements can be made, and these should also be considered within the scope of protection of this utility model.
