[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figure 1-8 As shown, an embodiment of a torque converter cage forming die includes:

[0031] Upper template 1 has a forming cavity area 11;

[0032] The lower template 2 is provided with a forming punch area 21;

[0033] A piercing punch 3 is provided in the forming punch area 21; the forming punch area 21 with the piercing punch 3 is in a convex-concave fit with the forming die area 11.

[0034] The retainer process component 4 is disposed in the forming punch area 21; the circumferential edge of the retainer process component 4 is circular; the retainer process component 4 is provided with a limiting ear 41 in the circumferential direction, and a positioning hole 42 is provided in the center.

[0035] The structure of the cage component 4 in this embodiment is as follows: Figure 3 As shown, compared to Figure 2 In this embodiment, the structure of the cage process component 4 is further reduced to minimize the waste material around the cage process component 4, so as to adapt to the final cage structure and improve the stability of the process component during molding, thereby reducing the impact of excessive waste material on the molded product.

[0036] Specifically, Figure 2 In the existing technology, the retainer component 4 to be molded has a square periphery. Through holes are provided along the square edges to fix the square retainer component 4 onto the molding die; while Figure 3 In this embodiment, the circumferential edge of the retainer process part 4 to be formed is circular. Only the limiting ear 41 is provided on the circumferential edge of the process part to facilitate the fixation of the retainer process part 4 on the forming mold. At the same time, the center of the retainer process part 4 is provided with a positioning hole 42. The positioning hole 42 cooperates with the limiting ear 41 to fix the retainer process part 4 on the forming mold.

[0037] like Figure 8 The diagram shows the cage process structure after molding. During mold closing, the forming punch area 21 and the forming die area 11 engage to achieve the flanging forming of the cage process component 4. The forming die area is provided with a forming groove that engages with the flanging punch 3. Specifically, as shown... Figure 3 As shown, the retainer part 4 to be formed has multiple punches 43 formed by blanking in the previous process; after mold closing, the upper template 1 and the lower template 2 clamp the retainer part 4 between them, and the piercing punch 3 passes through the punches 43 and engages with the forming groove 14 in the forming die area to realize the piercing forming of the retainer part 4.

[0038] like Figure 4-5 As shown, in another preferred embodiment, the circumferential edge of the forming punch area is circular, and the circumferential edge of the forming die area 11 is also circular.

[0039] Furthermore, in this embodiment, the forming punch area and the forming die area 11 cooperate to achieve the flanging forming of the cage process part 4; the circular design fits the outer edge shape of the cage process part 4, and the forming punch area and the forming die area 11 abut against the cage process part 4 with a small area.

[0040] Since the area where the retainer process part 4 is sandwiched between the upper mold plate 1 and the lower mold plate 2 is only the corresponding area of ​​the forming punch area and the forming die area 11, the contact surface between the mold and the retainer process part 4 is small, the stamping pressure is more concentrated when the upper and lower molds are closed, and the stamping effect is better.

[0041] like Figure 4 , Figure 6-7As shown, in another preferred embodiment, the forming punch area is provided with a positioning pin 22, which passes through the positioning hole 42 to fix the retainer process part 4.

[0042] Furthermore, two limiting pins 23 are provided on the edge of the forming punch area, and a limiting ear 41 is sandwiched between the two limiting pins 23.

[0043] The cage component 4 is fixed to the forming punch area by the design of positioning hole 42 and limiting pin 23, so as to facilitate subsequent stamping and flanging.

[0044] Furthermore, the piercing punch 3 corresponds one-to-one with the punch 43 on the cage process part 4, and the piercing punch 3 also plays a limiting role for the cage process part 4.

[0045] like Figure 5 As shown, in another preferred embodiment, the forming die area 11 is provided with a positioning groove 12 that engages with the positioning pin 22.

[0046] Furthermore, the forming die area 11 is provided with a limiting groove 13 that engages with the limiting pin 23.

[0047] The positioning groove 12 and the limiting groove 13 provide accommodating space for the positioning pin 22 and the limiting pin 23 in the mold closing state; at the same time, they also provide a guiding function for mold closing, and detect whether the upper and lower molds are aligned before mold closing.

[0048] like Figure 4-7 As shown, in another preferred embodiment, an upper mold base 5 is fixedly connected to the upper surface of the upper mold 1, a lower fixing plate 6 is fixedly connected to the lower surface of the lower mold 2, and a lower mold base 7 is fixedly connected to the lower surface of the lower fixing plate 6; a guide mechanism 8 is provided between the upper mold base 5 and the lower mold base 7.

[0049] The upper mold base 5, the lower mold base 7, and the lower fixing plate 6 further fix the upper template 1 and the lower template 2; the guide mechanism 8 provides guidance for the movement between the upper mold base 5 and the lower mold base 7, ensuring the accuracy of mold closing positioning and alignment.

[0050] Furthermore, the guiding mechanism 8 consists of a guide post 81 and a guide hole 82. The guide post 81 is disposed on the lower mold base 7, and the guide hole 82 is disposed on the upper mold base 5. The guide post 81 and the guide hole 82 are slidably engaged so that the upper mold base 5 moves relative to the lower mold base 7 along the guide post 81.

[0051] When this utility model is in operation: In the open mold state between the upper template 1 and the lower template 2, the retainer process component 4 is fixed to the upper surface of the lower template 2. The positioning hole 42 of the retainer process component 4 is in concave-convex fit with the positioning pin 22, the punch 43 is in concave-convex fit with the flipping punch 3, and the limiting ear 41 is clamped between the two limiting pins 23. The upper template 1 is pressed down along the guide mechanism 8 and closes to the lower template 2 to complete the flanging forming of the retainer process component 4. The upper template 1 moves upward to open the mold.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
