Description

Forming processing casting mechanism of low-stress casting for vehicle Technical Field The invention relates to the technical field of casting processing and casting, in particular to a molding processing and casting mechanism of a low-stress casting for a vehicle. Background The low-stress casting for the automobile is in the field of automobile manufacturing, has increasingly severe requirements on the performance of the casting, particularly has low-stress characteristics, can effectively reduce the deformation and cracking risks in the use process, and improves the service life and reliability of automobile parts. In order to overcome the above-mentioned defect, the first prior art (Chinese patent publication No. CN218799066U, publication day 2023-04-07) is a casting processing and casting device, which solves the problems that in the prior art, when the casting device encounters a metal solution in the actual use process, the condition that the metal solution residues are adsorbed on the bottom of an inner cavity of the blanking structure easily occurs, if the metal solution residues are not cleaned timely, other solutions are possibly mixed with the residues in the blanking structure in the next processing, so that the purity of the solution is reduced, and the production is affected, so that personnel need to clean the residues at the blanking structure after each use of the device, and the problem of the use burden of personnel is improved. In addition, the second prior art (China patent publication No. CN116037870A, publication No. 2023-05-02) is a metal casting device for casting processing, belongs to the technical field of metal casting, and aims to solve the problems that in the process of mass production of the existing casting device, single casting, cooling, demoulding and blanking are often needed, the overall working efficiency is not high enough, molten metal is conveyed into the casting assembly from bottom to top through a feeding assembly, the casting assembly is drained when driven to rotate to a negative pressure foam draining part position by a rotating seat, the casting assembly is externally connected with a pipeline after foam draining, water is conveyed from a water inlet pipe through a water outlet pipe, the casting assembly is cooled in a circulating manner, then cooling water of the casting assembly is drained, and finally the formed casting is taken out from the side of a base, so that continuous casting can be realized, the working efficiency is high, and the control is simpler. In the traditional casting mechanism, if the die is positioned inaccurately during the molding and processing process, the size of a die cavity can be deviated, the stress of molten metal is uneven during the filling and solidification processes, so that stress concentration is generated, and if a forced ejection mode is adopted during demolding, the casting can be extruded or pulled, so that the stress is further increased. In addition, after the die cavity is used for many times, impurities such as metal scraps, oxide scales and the like are easy to remain on the surface, and if the impurities are not cleaned timely, the surface quality of the casting can be affected, and an additional stress source can be introduced during casting molding. Therefore, the development of a forming processing casting mechanism capable of effectively controlling stress generation and improving casting quality in the casting process has important practical significance. We have therefore proposed a forming and casting mechanism for low stress castings for vehicles in order to solve the problems set out above.
