Processing structure and processing method of plastic components

Abstract

The invention provides a machining structure and a machining method of a plastic component. The plastic component comprises an annular structure. The machining method for the plastic component comprises the following steps of: providing a machining mold, wherein the machining mold comprises an annular mold cavity and a material overflowing groove, the annular mold cavity and the material overflowing groove are communicated, and a cross sectional area of a joint between the material overflowing groove and the annular mold cavity is smaller than the cross sectional areas of the other parts of the material overflowing groove; adding liquid-state injection molding materials to fill the annular mold cavity and the material overflowing groove; forming the machining structure of the plastic component, wherein the machining structure comprises the annular structure and an overflowing plastic part, and the cross sectional area of the joint between the overflowing plastic part and the annular structure is larger than the cross sectional areas of the other parts of the overflowing plastic part; and separating the overflowing plastic part from the machining structure of the plastic component, and forming the plastic component having the annular structure. The invention further provides the plastic component machined by using the machining method.

Description

technical field [0001] The invention relates to a processing structure and processing method of a plastic component, in particular to a processing method of a plastic component with a ring structure. Background technique [0002] Existing plastic components often need to be processed into various shapes according to design requirements. Plastic components with ring structures are mainly processed by injection molding. As we all know, in the injection molding process, there is often a weld line in the plastic component, and the existence of the weld line will lead to a decrease in the product reliability of the plastic component, because the stress is relatively concentrated where the weld line exists in the plastic component , is the weakest part of the ring structure, and it is also the place where it is most likely to break. Therefore, how to effectively improve the strength of the weld line is an urgent problem to be solved in the industry. [0003] In view of the above...
