Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of mold-related technology, and more specifically, to a clutch pressure plate casting mold. Background Technology

[0002] In the casting production of clutch pressure plates, the mold plays a crucial role. However, existing clutch pressure plate casting molds have significant defects, severely impacting production efficiency and product quality. Current mold structures are poorly designed in terms of cooling and demolding processes; the cooling systems are often inadequate, failing to cool the formed clutch pressure plate quickly and evenly. This not only prolongs the production cycle and reduces production efficiency but may also lead to internal stress in the pressure plate due to uneven cooling, affecting the product's mechanical properties and dimensional accuracy.

[0003] Meanwhile, the demolding process is also fraught with difficulties. The mold structure does not adequately consider the ease of demolding, causing the pressure plate to easily stick to the mold during demolding. This requires a lot of time and manpower for demolding operations, and forced demolding may also cause damage and deformation to the surface of the pressure plate, increasing the scrap rate and raising production costs.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a clutch pressure plate casting mold, which solves the technical problems in the prior art where the mold structure is poorly designed in the cooling and demolding stages, the cooling system is often not perfect, and it is impossible to cool the formed clutch pressure plate quickly and evenly.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a clutch pressure plate casting mold, comprising:

[0007] The upper mold base, the lower mold base, several movable columns, and the first spring are provided. The movable columns are all fixed at the four opposite corners of the bottom surface of the upper mold base. The movable columns are all movably fitted inside the lower mold base. The first spring is fitted on the movable columns.

[0008] The upper mold and the fixing component are provided, wherein the upper mold is disposed within the upper mold base and the fixing component is disposed between the upper mold and the upper mold base;

[0009] The bottom groove, the lower mold, and the cooling connection assembly are provided. The bottom groove is formed on the surface of the lower mold base, the lower mold is installed in the bottom groove, and the cooling connection assembly is disposed between the bottom groove and the lower mold.

[0010] The cooling connection assembly includes a cooling inner shell, which is fixed to the bottom surface of the bottom groove. A plurality of connecting rods are provided on the bottom surface of the lower mold. The connecting rods are movably fitted inside the lower mold base. A base plate is provided at the bottom of the connecting rods, and a second spring is fitted on the connecting rods.

[0011] As a further technical solution, the bottom of the lower mold is provided with a sleeve groove, which is fitted onto the outside of the cooling inner shell. A pair of circulation pipes are provided at the bottom of the lower mold base, and the circulation pipes are both connected to the cooling inner shell.

[0012] As a further technical solution, limit grooves are provided on both opposite end faces of the bottom groove, and limit blocks are provided on both opposite end faces of the lower mold side surface, with the limit blocks located in the limit grooves.

[0013] As a further technical solution, telescopic cylinders are provided on both opposite sides of the outer surface of the lower mold base, and a fixing plate is provided at the output end of the telescopic cylinder, with the fixing plate attached to the upper end surface of the limiting block.

[0014] As a further technical solution, the fixing component includes a circular groove, which is formed on the top of the upper mold base. The upper mold is installed in the circular groove, and the upper mold and the upper mold base are screwed together by a number of bolts.

The second spring assists in the demolding of the lower mold, and the limiting groove and limiting block cooperate to ensure accurate positioning of the lower mold. The telescopic cylinder and the fixed plate enhance the fixing effect and facilitate demolding operation.

[0020] 2. The beneficial effects of the fixing components in this disclosure are that the design of the circular groove and bolts facilitates the installation and disassembly of the upper mold, enables precise positioning during installation, and facilitates cleaning and maintenance of the mold during disassembly, thereby improving the versatility and service life of the mold.

[0033] like Figures 1-4 As shown, it illustrates a clutch pressure plate casting mold according to an embodiment of the present disclosure, comprising:

[0034] The lower mold base 1, the upper mold base 2, several movable columns 3 and the first spring 4 are all fixed at the four opposite corners of the bottom surface of the upper mold base 2. The movable columns 3 are all movably fitted inside the lower mold base 1. The first spring 4 is fitted on the movable columns 3.

[0035] The upper mold 5 and the fixing component 9 are provided. The upper mold 5 is set inside the upper mold base 2, and the fixing component 9 is set between the upper mold 5 and the upper mold base 2.

[0036] The bottom groove 6, the lower mold 7, and the cooling connection assembly 8 are provided. The bottom groove 6 is opened on the surface of the lower mold base 1, the lower mold 7 is installed in the bottom groove 6, and the cooling connection assembly 8 is disposed between the bottom groove 6 and the lower mold 7.

[0037] The cooling connection assembly 8 includes a cooling inner shell 8-1, which is fixed to the bottom surface of the bottom groove 6. Several connecting rods 8-2 are provided on the bottom surface of the lower mold 7. The connecting rods 8-2 are movably fitted inside the lower mold base 1. A base plate 8-3 is provided at the bottom of the connecting rods 8-2. A second spring 8-4 is fitted on the connecting rods 8-2. A sleeve groove 8-5 is opened at the bottom of the lower mold 7 and is fitted outside the cooling inner shell 8-1. A pair of circulation pipes 8-6 are provided at the bottom of the lower mold base 1. Both circulation pipes 8-6 are connected to the cooling inner shell 8-1. Limiting grooves 8-7 are opened on both opposite end faces of the bottom groove 6. Limiting blocks 8-8 are provided on both opposite end faces of the side surface of the lower mold 7. The limiting blocks 8-8 are located in the limiting grooves 8-7. Telescopic cylinders 8-9 are provided on both opposite sides of the outer surface of the lower mold base 1. A fixing plate 8-10 is provided at the output end of the telescopic cylinder 8-9 and is attached to the upper end face of the limiting block 8-8.

[0038] In some examples, the fixing and cooling / demolding of the lower mold 7 are crucial in the mold forming process, directly affecting product quality and production efficiency. Therefore, a cooling connection assembly 8 is designed. This assembly includes a cooling inner shell 8-1 fixed to the bottom surface of the bottom groove 6, which is the main low-temperature transfer component. Several connecting rods 8-2 are mounted on the bottom surface of the lower mold 7 and are movably fitted inside the lower mold base 1. This movable connection ensures the stability of the lower mold 7 during sliding. The base plate 8-3 at the bottom of the connecting rods 8-2 provides support and distributes the force. The second spring 8-4 mounted on the connecting rods 8-2 acts as a buffer during mold operation, reducing impact and assisting the lower mold 7 in upward movement during demolding. A slot 8-5 at the bottom of the lower mold 7 fits outside the cooling inner shell 8-1, achieving a tight connection between the lower mold 7 and the cooling inner shell 8-1, ensuring efficient cooling of the lower mold 7 by the cooling medium. A pair of circulating... Pipes 8-6 are all connected to the cooling inner shell 8-1. The cooling medium circulates in the cooling inner shell 8-1 through the circulation pipes 8-6, continuously carrying away the heat from the lower mold 7, accelerating the cooling speed of the molded product, and enabling better demolding. Limiting grooves 8-7 are opened on both opposite end faces of the bottom groove 6, which cooperate with limiting blocks 8-8 set on opposite ends of the side surface of the lower mold 7. The limiting blocks 8-8 are located within the limiting grooves 8-7, restricting the horizontal displacement of the lower mold 7 and ensuring the mold operates smoothly during operation. For positioning accuracy, telescopic cylinders 8-9 are set on opposite sides of the outer surface of the lower mold base 1. The fixed plate 8-10 set at the output end of the cylinders 8-9 is attached to the upper end face of the limit block 8-8. When it is necessary to fix the lower mold 7, the telescopic cylinders 8-9 extend and the fixed plate 8-10 presses tightly against the limit block 8-8, which further enhances the fixing effect of the lower mold 7. When demolding, the telescopic cylinders 8-9 retract, releasing the pressure on the limit block 8-8, so that the lower mold 7 can move upward smoothly for demolding under the action of the second spring 8-4.

[0039] like Figures 1-4 As shown, this embodiment proposes a fixing component 9 including a circular groove 9-1, which is opened on the top of the upper mold base 2. The upper mold 5 is installed in the circular groove 9-1, and the upper mold 5 and the upper mold base 2 are screwed together by a number of bolts 9-2.

[0040] In some examples, in order to facilitate the disassembly and cleaning of the lower mold 7, a fixing component 9 is designed. This component includes a circular groove 9-1 and is formed in the upper mold base 2. The upper mold 5 is installed in the circular groove 9-1 and inserted into it. The bolt 9-2 that screws the upper mold 5 to the upper mold base 2 can firmly fix the upper mold 5 in the upper mold base 2 and can be disassembled at any time.

[0041] For example, such as Figure 4 As shown, the upper surface of the fixing plate 8-10 is flush with the surface of the lower mold base 1.

[0042] In some examples, the flat structure allows the upper mold base 2 and the lower mold base 1 to fit together without restriction, and they can fit tightly and be fixed.

[0043] For example, such as Figure 3 As shown, the cross-section of the cooling inner shell 8-1 has an L-shaped structure.

[0044] In some examples, the L-shaped structure allows the cooling inner shell 8-1 to simultaneously transfer low temperatures to the bottom and sides of the mold 7, thus removing heat more quickly.

[0045] For example, such as Figure 3 As shown, the lower mold 7 and the inner wall of the bottom groove 6 are sealed and fitted together.

[0046] In some examples, the cooling effect between the cooling inner shell 8-1 and the lower mold 7 is improved through a sealing and bonding effect.

[0047] In actual use: First, install the upper mold 5 in the circular groove 9-1 of the upper mold base 2 and fix it with bolts 9-2. Then, install the lower mold 7 in the bottom groove 6, so that the limiting block 8-8 is inserted into the limiting groove 8-7. Open the telescopic cylinder 8-9 to let the fixing plate 8-10 fit against the limiting block 8-8 to fix the lower mold 7. Inject the molten material into the top of the upper mold 5. After molding, the cooling medium circulates in the cooling inner shell 8-1 through the circulation pipe 8-6 to cool the lower mold 7 and the formed clutch pressure plate. Close the telescopic cylinder 8-9. Under the action of the second spring 8-4, the lower mold 7 moves upward along the connecting rod 8-2 to assist in demolding.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
