Description

Dislocation preventing locking mechanism of double guide rings of injection mold Technical Field The invention belongs to the technical field of injection molds, and particularly relates to an anti-dislocation locking mechanism of a double guide ring of an injection mold. Background The injection mold is used as core equipment in an injection molding process, and the function of the injection mold is important. The plastic in a molten state is injected into a closed space formed by a cavity and a core together through high pressure, and after the plastic is cooled and solidified, a required product can be formed. The injection mold is complex and delicate in structure and generally comprises a plurality of key parts such as a pouring system, a guiding mechanism, an ejection system, a cooling system, an exhaust system and the like. According to the complexity, the injection mold may be divided into two-plate mold, three-plate mold, hot runner mold, and the like. In terms of material selection, die steel or aluminum alloy having high hardness and excellent wear resistance is often preferred to ensure durability and stability of the die. In the design process, the layout of the parting surface, the uniformity of the wall thickness, the rationality of the demoulding inclination, the optimal design of the reinforcing ribs and the like are comprehensively considered so as to ensure the quality of the product and the service life of the die.

In the prior art, double guide ring dislocation preventing locking mechanisms of injection molds generally rely on guide posts and guide holes to perform both guiding and positioning functions. However, in the process, due to the influence of factors such as equipment vibration and external collision, the positioning accuracy of the guide post and the guide hole may be affected, and thus the rapid and stable locking between the cavity and the core cannot be realized in the injection molding process. The problem of clearance in the injection molding process can be caused, so that burrs are increased, the defective rate is increased, the quality rate of products is reduced, the processing efficiency of the injection mold is adversely affected, and meanwhile, when the guide mechanism is locked, impurities often caused by long-time work remain on the locking surface of the guide mechanism, so that the locking contact surface is easy to cause hidden danger of accelerated abrasion due to the residual impurities, and the locking efficiency of the guide mechanism is reduced.
