Description

Technical Field

[0001] This utility model relates to the technical field of clutch disc processing equipment, and in particular to a clutch disc hot pressing mold with an ejection mechanism. Background Technology

[0002] Traditional clutch face plate hot pressing molds generally adopt a single-cavity overflow structure, which has the following technical defects: after molding, the product is tightly bonded to the mold cavity, requiring workers to use pry tools to forcibly peel it off, which can easily cause the product edges to curl and deform, resulting in an increased scrap rate; in addition, when manually removing the plates, the hands are close to the high-temperature mold (working temperature 150-180℃), which poses a risk of burns. Utility Model Content

[0003] (1) Technical solution

[0004] To solve the above-mentioned technical problems, this utility model provides a clutch disc hot pressing mold with an ejection mechanism, including an upper mold heating plate, a hot pressing mold with a mold cavity, and an ejection mechanism for ejecting the disc from the mold cavity. The ejection mechanism includes a pin and a pry plate for prying the pin up. The lower part of the hot pressing mold is provided with a hollow part, and the bottom of the mold cavity is provided with a countersunk hole. The pin is disposed in the countersunk hole with clearance fit.

[0005] Preferably, the mold cavity is provided in a plurality of forms arranged in a circular array.

[0006] Preferably, the depth of the countersunk hole is 3-5 mm.

[0007] Preferably, the tail of the pin is provided with anti-slip texture, and the head end face is flush with the bottom surface of the mold cavity.

[0008] Preferably, the height of the hollowed-out portion is 15-20mm.

[0009] (2) Beneficial effects

[0010] This utility model provides a clutch disc hot pressing mold with an ejection mechanism. Compared with the prior art, this utility model has the following advantages:

[0011] 1. Improved demolding efficiency: The ejection mechanism greatly shortens the demolding time, improving efficiency compared to traditional demolding methods;

[0012] 2. Increased yield: Avoids deformation caused by manual prying, greatly reducing the scrap rate;

[0013] 3. Multi-cavity synchronous production: The ring mold cavity is set with several cavities and distributed in a ring array, which increases the number of molded at one time and improves work efficiency;

[0014] 4. Operational safety: Operators do not need to directly contact the high-temperature mold cavity, reducing the risk of burns. Attached Figure Description

[0019] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 , 2 As shown, the present invention discloses a clutch disc hot pressing mold with an ejection mechanism, comprising an upper mold heating plate 1, a hot pressing mold 2 with a mold cavity 3, and an ejection mechanism for ejecting the disc 6 from the mold cavity 3. The ejection mechanism includes a pin 4 and a pry plate 5 for prying the pin 4 to lift it up. The lower part of the hot pressing mold 2 is provided with a hollow part 21, and the bottom of the mold cavity 3 is provided with a countersunk hole 31. The pin 4 is disposed in the countersunk hole 31 with clearance fit.

[0021] The mold cavity 3 is provided with several of them and is arranged in a ring array. The depth of the countersunk hole 31 is 3-5mm.

[0022] The tail of the pin 4 is provided with anti-slip texture to increase the prying friction. The head end face is flush with the bottom surface of the mold cavity. The hollow part 21 has a height of 15-20mm, forming an ejection operation space.

[0023] Workflow:

[0024] Loading stage: The clutch face plate winding blank is placed into the mold cavity 3, and the upper mold heating plate 1 is closed for hot pressing.

[0025] Mold opening stage: After the hydraulic press raises the upper mold, the operator inserts the pry bar 5 into the hollow part 21;

[0026] Top-out stage: such as Figure 1 As shown, the front end of the pry bar abuts against the anti-slip textured area at the tail of pin 4, and prys the tail of pin 4 upward, so that the head of the pin pushes the hot-pressed blank out of the mold cavity by 1.5-2mm.

[0027] Removal stage: Use pliers to grip the protruding part to safely remove the part. Throughout the process, hands do not come into contact with the high-temperature surface of the mold.

[0028] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
