Description

TECHNICAL FIELD

[0001] The utility model relates to mould technical field, concretely is a circuit breaker shell mould's cooling waterway. BACKGROUND

[0002] In the production process of the low-voltage small circuit breaker shell mould of the electric appliance, the traditional cooling waterway design has many problems. The previous design directly utilizes the water well to cool, and this mode often cannot realize sufficient and balanced cooling effect when cooling the product. Because of insufficient and unbalanced cooling, the internal stress is easily affected in the releasing process, and the internal structure of the product will also have problems due to improper cooling. These factors comprehensively cause the product to have the phenomenon of uneven deformation shrinkage, and the product has a large degree of warping deformation. This not only causes the product cover and seat to have misalignment and non-tightness when being assembled after complete cooling, but also causes the product size precision to be difficult to meet the requirements, which seriously affects the quality of the product.

[0003] In addition, the traditional cooling waterway design causes low product qualification rate, which indirectly causes a long injection molding cycle. The long injection molding cycle means low production efficiency, and in the large-scale production process, this will significantly increase the production cost and reduce the market competitiveness of the enterprise. Therefore, there is an urgent need for a new cooling waterway design to solve these problems to improve product quality, shorten the production cycle, and thus reduce production cost and improve production efficiency.
