Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a multi-cavity connector shell injection mold. Background Art

[0002] Connectors are a component that electronic engineers often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc. For example, the connector for lighting on the court is very different from the connector for the hard disk drive and the connector for igniting the rocket. But no matter what kind of connector, it must ensure that the current flows smoothly, continuously and reliably.

[0003] A connector is generally composed of a connector housing and terminals. The terminals are installed in the connector housing. During the production process, the terminals are die-casted and the connector housing is injection molded. The traditional molding mold has a mold cavity opened on the upper mold and the lower mold. This method can only inject one plastic shell at a time and cannot achieve mass production.

[0004] Therefore, we propose a multi-cavity connector shell injection mold to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-cavity connector shell injection mold to solve the problems raised in the above background technology.

[0008] Preferably, the insides of the six frames are all fixedly connected with forming blocks, and the tops of the six pressure plates are all provided with vertical tubes, and the vertical tubes are provided to inject plastic into the inside of the frames.

[0009] Preferably, a cavity is provided inside the lower mold, and the demolding mechanism includes a through hole, a top sheet and a connecting rod. The through hole is provided at the bottom of the inner wall of the injection molding groove, the top sheet is movably connected to the inside of the through hole, and the connecting rod is fixedly connected to the bottom of the top sheet. The top sheet is provided to be able to push the connector shell after molding, and the initial position of the top sheet is flush with the bottom of the inner wall of the injection molding groove.

[0010] Preferably, the outer wall of the connecting rod is fixedly sleeved with a circular plate, one end of a spring is fixedly connected to the top of the circular plate, and the other end of the spring is fixedly connected to the top of the inner wall of the cavity. The spring sleeve is arranged on the outer wall of the connecting rod. The spring and the circular plate are arranged to provide elastic force to drive the top plate to move upward.

[0011] Preferably, a connecting plate is fixedly installed at the bottom of the connecting rod, and a mounting plate is fixedly installed on the connecting plate. The number of connecting plates is two, and the mounting plate can drive multiple connecting rods to move downward at the same time through the two connecting plates.

[0012] Preferably, a trapezoidal block 1 is fixedly installed on the top of the mounting plate, and the top inclined surface of the trapezoidal block 1 abuts against the trapezoidal block 2. An electric push rod is fixedly installed inside the cavity, and the trapezoidal block 2 is fixedly installed on the output end of the electric push rod. The electric push rod is provided to drive the trapezoidal block 2 to move left and right. The inclined surface of the trapezoidal block 2 can squeeze the inclined surface of the trapezoidal block 1, thereby causing the trapezoidal block to move down and drive the top plate to retract into the inside of the through hole.

[0013] Preferably, a limit block is fixedly installed on the top of the inner wall of the cavity, and a connecting block is fixedly installed on the top of the trapezoidal block 2. By setting the limit block and the connecting block, excessive displacement of the trapezoidal block 2 can be prevented.
