A mold for the production of automobile parts with a cooling structure

Abstract

The invention discloses a vehicle part production mould provided with a cooling structure. The vehicle part production mould comprises a rack body; a lower mould is fixedly arranged on the bottom of the rack body; an upper mould is connected to the top of the rack body; high-efficient heat conduction mechanisms are connected to the upper and lower moulds; each high-efficient heat conduction mechanism comprises a heat dissipation sleeve ring; the side wall of each of the upper and lower moulds are correspondingly internally provided with heat conduction plate in an embedding manner; every two adjacent heat conduction plates as well as each heat conduction plate at the outermost side and the corresponding heat dissipation sleeve ring are connected through heat conduction blocks; a heat dissipation inlet and a heat dissipation outlet are formed in the side surface of each heat dissipation sleeve ring; the heat dissipation inlet is connected with the corresponding heat dissipation outlet through heat dissipation through holes; and each heat dissipation sleeve ring is connected with a double-mode heat dissipation mechanism. By adopting the device, on one hand, the upper mould and the lower mould can be cooled, and moving of the upper mould is not affected; on the other hand, deformation of the moulds under high pressure can be avoided; furthermore, through sequential performing of combination of water cooling and air cooling and single water cooling, the cooling effect of the device can be ensured; and besides, defective influence cannot be generated.

Description

technical field [0001] The invention relates to the field of auto parts production, in particular to a mold with a cooling structure for the production of auto parts. Background technique [0002] Nowadays, some auto parts are produced in large batches. If a single process is used for production, the number of corresponding processes will be large and the efficiency will be very low. It is difficult to meet the requirements in batches. At this time, it is necessary to use extrusion or stamping continuous molds for production. Can greatly improve production efficiency. [0003] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obt...

AI Technical Summary

Problems solved by technology

[0007] (1) Stamping dies for automobile production generally include a fixed lower die and a moving upper die. The cooling of the lower die is easy to achieve, but it is difficult to cool the upper die due to continuous movement. Therefore, the cooling mechanism of the existing die is generally It is mainly aimed at the lower mold, which makes the overall cooling effect of the device unsatisfactory;

[0008] (2) When the stamping die for automobile production is working, the upper die and the lower die will be squeezed violently, and in order to cool the die, there will be certain through holes and gaps between the die itself or the die and the shell. These through holes , The gap is easy to deform the mold under high pressure, which affects the quality of parts processing;

[0009] (3) Although it is convenient to use air cooling to cool the mold, the thermal conductivity of the air is very low, which makes the cooling effect of the device not good. Although the cooling effect of the mold is good by using circulating water, when the temperature of the mold is high, the circulating water Vigorous gasification can easily cause the water pipe to expand and rupture, or the water flow will be interrupted, which will affect the cooling process
