Socket shell injection molding mold uniform in glue injection

Abstract

Disclosed is a socket shell injection molding mold uniform in glue injection. The socket shell injection molding mold uniform in glue injection comprises a movable mold core, a fixed mold core and a glue injection assembly. The movable mold core is buckled on the fixed mold core. An injection molding cavity for injection molding a socket shell is formed between the movable mold core and the fixedmold core. The movable mold core comprises a bottom plate and a boss. The boss is disposed on the bottom plate. The boss is provided with a slideway. The glue injection assembly comprises a glue injection block and a guide block. The glue injection block is slidably arranged in the slideway. A glue flowing groove is formed in the glue injection block to enable plastic to enter the injection molding cavity from the glue flowing groove. Therefore, the injection molding of the socket shell is achieved, the outer surface of the socket shell does not have feeding marks, and the smoothness is kept.Furthermore, the glue injection block is arranged in the slideway in a penetrating mode, and one end, connected with the injection molding cavity, of the glue injection groove is located at the position close to the center of the boss, so that the plastic can flow around from the middle position of the injection molding cavity, glue injection is uniform, the problem of deformation of the formed socket shell is effectively prevented, and the forming quality is further improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for socket shells with uniform glue injection. Background technique [0002] Injection mold is a tool for forming plastic products. The mold usually includes a movable mold and a fixed mold. The movable mold and the fixed mold together form a cavity. The plastic is injected into the cavity by an injection molding machine, and the plastic is cooled in the cavity. , and then separate the movable mold from the fixed mold to obtain the plastic product in the cavity. [0003] see figure 1 , is a socket housing 10, the socket housing 10 is provided with an accommodating groove 11 and a side hole 12, and the side hole 12 communicates with the accommodating groove 11. For the socket housing 10, the conventional injection molding method is to set a plastic mold on the fixed mold inlet, and make the plastic inlet directly communicate with the molding cavity of t...

Problems solved by technology

[0004] However, for the conventional injection molding method, if the plastic inlet is directly opened on the fixed mold so that the molten plastic enters the molding cavity directly from the plastic inlet, the plastic nozzle of the socket housing 10 will be arranged on the outer surface of the socket housing 10 , it will cause the smoothness of the outer surface of the socket housing 10 to decrease; furthermore, if the plastic nozzle of the socket housing 10 is arranged on the side wall of the accommodating groove 11, since the socket housing 10 is a shell-shaped structure, it is easy to cause glue injection. Uneven, so that the molded socket shell 10 is deformed, resulting in a decline in the quality of the socket shell 10
