Pure water conditioning system of engineering plastic retaining frame

Abstract

The invention relates to a pure water conditioning system of an engineering plastic retaining frame, and belongs to the technical field of injection molding. The pure water conditioning system comprises a pure water device, a steam outlet device, a special water tank, retaining frame positioning and arranging shelves and a water tank electric control system, wherein the pure water device is connected through a pipeline, and the other end of the pipeline is connected with the special water tank; the retaining frame positioning and arranging shelves are arranged in a cavity body of the water tank; the steam outlet device is arranged at the upper part of the special water tank, and the other end of the special water tank is connected with the water tank electric control system through a pipeline. Due to the treatment of the pure water device, water stains of a product are completely avoided; the surfaces of the retaining frame positioning and arranging shelves subjected to pure water treatment are uniform in color and free from any water stain and scratch due to collision, and the size stability and the mechanical performance indexes such as the impact toughness and the fatigue resistance of the retaining frame positioning and arranging shelves are improved; the customer requirements are satisfactorily met by the product and clean production environments of enterprises are created.

Description

technical field [0001] The invention relates to a pure water conditioning system for an engineering plastic cage, belonging to the technical field of injection molding. Background technique [0002] At present, engineering plastic cages for rolling bearings processed by injection molding process, in order to eliminate the internal stress of the product, improve the dimensional stability of the product, and improve the impact toughness of the product, after injection molding, a follow-up treatment is required. The post-treatment method generally uses steam. The method of steaming or boiling in hot water, regardless of steaming or boiling, generally has the following problems that are difficult to solve: 1. The product is bumped and damaged to cause waste products; 2. The product is squeezed and deformed to cause waste products; 3. Water stains on the product surface. These problems lead to an increase in product waste, an increase in enterprise costs, a reduction in benefits,...

Problems solved by technology

[0002] At present, engineering plastic cages for rolling bearings processed by injection molding process, in order to eliminate the internal stress of the product, improve the dimensional stability of the product, and improve the impact toughness of the product, after injection molding, a follow-up treatment is required. The post-treatment method generally uses steam. The method of steaming or boiling in hot water, regardless of steaming or boiling, generally has the following problems that are difficult to solve: 1. The product is bumped and damaged to cause waste products; 2. The product is squeezed and deformed to cause waste products; 3. Water stains on the surface of the product

These problems lead to an increase in product waste, an increase in enterprise costs, a reduction in benefits, and a loss of profits; especially the water stains on the surface of the product cause the appearance of the product to be unqualified. What is more serious is that during the operation of the bearing, the water stain will fall off and enter the bearing roller This will seriously affect the precision and performance of the bearing, lead to early fatigue damage of the bearing, reduce the service life of the bearing, and cause equipment and even personal safety accidents
