[0030] This utility model provides a multi-process composite mold.

[0031] like Figure 1-4 As shown, the multi-process composite mold provided in this embodiment of the present invention includes an upper mold component and a lower mold component;

[0032] The lower mold component includes a lower mold base, a lower pad foot disposed on the lower mold base, a lower template foot disposed on the lower pad foot, and a lower mold core disposed on the lower template foot;

[0033] The upper mold component includes an upper mold base, an upper clamping plate disposed on the upper mold base, a punch fixing plate and a punch disposed on the upper clamping plate, a cutter block pad disposed on the punch fixing plate, and a cutter block disposed on the cutter block pad.

[0034] A pressure ring is arranged around the outer side of the lower mold core, and the pressure ring is arranged opposite to the cutting block. A pressure plate is arranged between the punch and the cutting block, and is arranged opposite to the lower mold core. Multiple sets of locking mechanisms are also evenly arranged between the upper mold component and the lower mold component. The locking mechanism includes a top block, a slider and a transmission rod. The top block is arranged on the lower mold plate, the transmission rod is connected to the pressure plate, and the slider is arranged on the upper clamping plate and is arranged opposite to the top block.

[0035] In this embodiment, the sheet metal drawing process can be completed in one stamping cycle by the cooperation of the pressure ring and the cutting block, within the stroke of the locking mechanism that prevents the pressure plate from moving. After the locking mechanism contacts the top block set on the lower die plate, the locking of the pressure plate is unlocked. The pressure plate cooperates with the lower die core to perform a retraction action, and the punch, cutting block of the upper die component and the lower die core of the opposite lower die component perform a shearing operation on the drawn sheet metal. At the bottom dead center of the press, the pressure plate and the opposite lower die core perform a pressing and correction of the sheet metal. This reduces the need for multiple dies to complete the processing of sheet metal parts, reduces tooling development costs, reduces the number of stamping equipment used, reduces the turnover of sheet metal stamping parts, and improves production efficiency.

[0036] The upper mold component also includes a return spring disposed on the upper clamping plate, the return spring acting on the pressure plate; the upper mold component also includes a complete locking mechanism except for the top block, the locking mechanism including the nitrogen spring, the nitrogen spring acting on the slider of the locking mechanism.

[0037] The lower die component also includes an elastic element disposed under the pressure ring, which acts on the pressure ring. Clearly, the elastic element is a nitrogen spring, serving as a pressure source for the blank forming process. It is uniformly arranged circumferentially along the lower die core and can provide sufficient and constant blank-holding force during the drawing process.

[0038] After a stamping cycle is completed, the upper die moves upward. At this point, all moving parts can be reset to their initial state by the reset element. After the product is removed, the next production cycle can be repeated.

[0039] Please refer to Figure 2-3 The lower template is provided with multiple guide sleeves, and the upper clamping plate is provided with multiple guide posts. The guide posts can be matched with the guide sleeves one by one. In this embodiment, the guiding ability of the upper mold component and the lower mold component when they move towards each other can be realized through the nesting effect of the guide sleeves and guide posts.

[0040] Furthermore, lower limit posts are evenly distributed on the lower template, and upper limit posts are correspondingly distributed on the upper clamping plate. The upper and lower limit posts are one-to-one, and when their end faces abut, they restrict the downward movement of the upper mold component. In this embodiment, when the upper mold component moves towards the lower mold component, the upper mold component is limited by the abutting and blocking action of the upper and lower limit posts.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
