Description

Technical Field

[0001] The utility model relates to the technical field of latch processing, in particular to an injection mold for a latch that can be quickly installed. Background Technique

[0002] A latch is a mechanical fastener, usually made of metal, which can be inserted into the door frame after the door is closed to prevent the door from being pushed open. The design of the latch mold needs to consider the specific shape, size and functional requirements of the latch to ensure that the produced latch can be accurately installed on various types of doors and provide a reliable locking function. The mold itself is usually made of high-strength materials to withstand the high pressure and high temperature environment during the production process.

[0003] In the use process of the existing latch injection mold, the mold is docked with the upper and lower two modules through positioning screws. This docking method requires screwing and fixing after determining the aligned position. This process requires a certain amount of time and energy. During this process, the operator needs to continuously adapt and position to ensure the correct position of the mold. Since the mold itself is heavy and inconvenient to move, this also increases the operation difficulty. All of the above factors will affect the positioning and installation rate, thereby reducing the use efficiency of the mold, and it is necessary to optimize and improve this. Content of the Utility Model

[0004] The purpose of the utility model is to provide an injection mold for a latch that can be quickly installed to solve the problems raised in the above background technique.
