[0002] With the development of the automotive industry, especially the rise of electric vehicles, the demand for cars is gradually increasing, making mass production of automobiles particularly important. Automotive molds are key equipment for completing the molding of automotive parts and achieving mass production of automobiles. Customized processing methods for automotive molds can improve the automation level of the automotive manufacturing industry.
[0003] Currently, stamping, a crucial machining process, plays a vital role in the national economy's processing industry. Sheet metal parts have extremely wide applications, penetrating all aspects of manufacturing, and sheet metal forming is primarily achieved through stamping dies. The stamping process offers a series of advantages, including high precision, high efficiency, good quality, cost savings, and conservation of materials and energy.
[0004] In modern life, in order to simultaneously punch, trim, and flip workpieces, pressure cores need to be set in both the upper and lower die bases. However, due to the limited space in the structure of composite molds, it is often impossible to set pressure cores in both the upper and lower die bases. Therefore, it is necessary to flip the workpieces upward and downward separately through different processes, resulting in low integration of composite molds. At the same time, because the workpieces are stamped and composite formed separately, only single workpieces can be processed, and multiple workpieces cannot be processed at once, which is costly and complicated.
[0005] Existing technology has flaws and needs improvement. Utility Model Content

[0025] The present invention will now be described in detail with reference to the accompanying drawings.
[0026] like Figures 1-3 As shown: A composite mold includes a base 1, a lower mold part 2, and an upper mold part 3. The lower mold part 2 is located in the upper middle part of the base 1. A first guide post 5 and a second guide post 6 are fixedly installed on the base 1. The first guide post 5 and the second guide post 6 are respectively located on both sides of the base 1. A first sliding part 7 and a second sliding part 8 are respectively provided at both ends of the upper mold part 3.

A stamping part 4 is provided at the top end of the upper mold part 3. The output end of the stamping part 4 passes through the upper mold part 3 and is connected to the punch.
[0027] It should be noted that the product to be processed is placed into the cavity of the lower die 2 by manual or automated arms. Then, the upper die 3 is driven by the stamping part 4 to perform a stamping composite processing on the product in conjunction with the cavity. Because multiple composite grooves are set in both the cavity and the punch, multiple products can be formed at one time, reducing waste and improving production efficiency. At the same time, because both the cavity and the punch are equipped with buffer and shock absorption components, the product is protected from damage caused by excessive downward pressure during the composite stamping process. The process is low-cost and highly efficient.
[0028] Preferably, both the first guide post 5 and the second guide post 6 can be configured as telescopic rods.
[0029] It should be noted that the telescopic rod, in conjunction with the sliding part set in the upper mold, can slide up and down during stamping. On the one hand, it supports the upper mold part 3 and the lower mold part 2, and on the other hand, it allows the upper mold base to move vertically up and down stably, preventing the product from being misaligned during the composite process.
[0030] Preferably, the die includes multiple fixing rods 41, a lower die fixing block 42, multiple grooves 43, multiple lifting cylinders, multiple lifting columns 44, and multiple lower die holes 45.

The lower die fixing block is provided with multiple grooves 43, and multiple lifting columns 44 are respectively provided in the multiple grooves 43. The output ends of the multiple lifting cylinders are respectively connected to the bottom ends of the multiple lifting columns 44 in the multiple grooves 43. The multiple lower die holes 45 are sequentially spaced around the multiple grooves 43.
[0031] It should be noted that the multiple lower die holes 45 are used to cooperate with the punches set in the upper die to press down and punch. After punching is completed, multiple lifting cylinders drive multiple lifting columns 44 to lift the punched product, so that the stamped product is ejected from the sheet metal.
[0032] Furthermore, at least three pairs of multiple fixing rods 41, multiple grooves 43, multiple lifting cylinders, multiple lifting columns 44, and multiple lower mold holes 45 are provided.
[0033] Preferably, the punch includes an upper die fixing block 31, multiple movable columns 32, multiple springs 33, multiple stampers 34, an upper die stamping plate 35, and multiple composite holes 36.

The function of multiple movable columns 32 and multiple springs 33 is to buffer the downward pressing force and distance of the multiple stamping presses 34, so as to avoid damage to the products due to excessive force or distance.
[0035] Furthermore, at least two pairs of each of the multiple movable columns 32, multiple springs 33, multiple stampers 34, and multiple composite holes 36 are provided.
[0036] Preferably, a U-shaped groove 37 is provided on the lower surface of the punch, and a U-shaped block 46 is provided on the lower surface of the die.
