DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] like Figure 1-2 As shown, the utility model relates to a production mold for automobile sunroof frame reinforcement, including a base 1, a lower mold base 2, an upper mold base 5 and a stamping plate 4, the bottom surfaces of the lower mold base and the base are both provided with a cavity area, and the design can reduce weight and save processing materials at the same time; the lower mold base is arranged in the middle of the top surface of the base; the top surface of the lower mold base extends outward to the surroundings to form a convex portion 3; the convex portion has a convex surface; the upper mold base 5 is arranged above the lower mold base; the bottom surface of the upper mold base has a slot in the middle, and a stamping plate 4 is arranged in the slot, and the stamping plate and the slot are fixed by bolts; the bottom surface of the stamping plate has an inner concave surface 31, and the convex portion and the inner concave surface are used together for pressurization; clamping mechanisms 6 for fixing the reinforcement are arranged on both sides of the bottom surface of the upper mold base.

[0020] As a technical improvement, a side seat 8 is arranged between the upper die seat and the base, and the side seat is located on both sides of the lower die seat. A clamping installation groove 51 is arranged on the bottom surface of the lower die seat, which is used to fix the clamping mechanism.

[0021] As a technical improvement, the side seat is in a "[" shape, and the side seat includes a top plate, a side plate and a bottom plate. The top surface and the bottom plate are arranged in parallel and spaced apart, and the two ends of the side plate are respectively fixed to the end of the top plate and the end of the bottom plate, and form an integral structure; a guide column 7 is arranged on the side seat, and through holes (not shown) are respectively arranged on the top plate and the bottom plate, and the guide column passes through the side seat through the through holes; a columnar retaining groove 9 is arranged at a position opposite to the bottom end of the guide column of the base.

[0022] In order to protect the processed surface, the convex part and the inner concave surface of the stamping plate are treated with quenching technology to increase the surface hardness and improve the surface finish of the mold, thereby reducing the normal wear rate of the mold and extending the service life of the mold.

[0023] As a technical improvement, the clamping mechanism is arranged at the top end of the guide column; the convex surface is opposite to the clamping surface of the clamping mechanism.

[0024] As a technical improvement, a lower pad 8 is arranged between the side seat and the top surface of the base, and the lower pad is fixed on the top surface of the base to play a buffering role.

[0025] As a technical improvement, an upper pad 11 is arranged between the bottom surface of the upper mold seat and the top surface of the side seat. The upper pad is fixed on the top surface of the side seat to play a buffering role. The upper pad and the lower pad are made of overlapping wooden boards and rubber layers, which can save costs in design.

[0026] As a technical improvement, the clamping mechanism comprises an upper clamping block 61 and a lower clamping block 62, wherein a convex tooth 601 is arranged on the bottom surface of the upper clamping block, and a concave mark 602 matching the convex tooth is arranged on the top surface of the lower clamping block.

A portion of the elastic pad is exposed from the notch of the mounting groove. After the edge position of the reinforcement is punched, it can rebound upward through the elastic pad, thereby facilitating the extraction of the reinforcement.

[0028] like Figure 3As shown, at the same time, in order to improve the technology, we consider the problem of wear resistance, wherein the surface position of the convex part and the surface position of the stamping plate are distributed from the outside to the inside in sequence, the self-lubricating layer 301, the connecting layer 302, the main wear-resistant layer 303 and the matrix, wherein the main wear-resistant layer is a nano multilayer composed of TiN, CrN and MoN alternately; the connecting layer is a nano multilayer composed of CrN and MoN alternately, and the self-lubricating layer is MoN. The base, the lower die seat, the upper die seat, and the clamping mechanism matrix are made of die steel, high-speed steel or cemented carbide.

Since the bottom surface of the upper clamping block is provided with convex teeth 601 and the top surface of the lower clamping block is provided with indentations 602, it can play an effective fixing role. This design has not yet been found in the prior art.
