Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold insert quick disassembly structure. Background Art

[0002] A mold is a tool for making molding components. When the mold is in use, injection molding is generally performed by closing the upper mold and the lower mold. The mold insert refers to a component installed on the mold to facilitate the mold to dissipate heat or change its shape.

[0003] The prior art (Announcement No.: CN 219130541 U) discloses a quick-assembly and disassembly insert structure for a mold, including an insert body, on which a plurality of groups of connecting through holes are opened, and fasteners are correspondingly inserted into the connecting through holes and connected to the mold, so that the insert body can be detachably connected to the mold.

[0004] Although the above patent fixes the insert body on the mold by fasteners, when replacing a different insert body, it is only necessary to loosen the fasteners and take out the insert body, and then replace the different insert body and lock it with the fasteners. The structure is simple, but there are the following disadvantages. When disassembling and installing, tools are required to rotate the fasteners, and the operation is relatively cumbersome, which increases the labor and operation steps of the workers, affects the efficiency of installation and disassembly, and needs further improvement. For this reason, we propose a mold insert quick disassembly structure. Utility Model Content

[0005] The main purpose of the utility model is to provide a mold insert quick disassembly structure, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0012] Preferably, the push rod is located at the lower end of the insert block.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By setting the fixing components, the insert block can be conveniently fixed and disassembled. When in use, the insert block is inserted into the card slot, and then the electromagnet is energized. The electromagnet generates magnetic force to adsorb the circular block, driving the circular block to move to the right, and the circular block drives the fixing rod into the fixing slot to complete the fixation. When disassembling, it is only necessary to cut off the power of the electromagnet, and the first spring drives the circular block to move to the left, and the circular block drives the fixing rod away from the fixing slot to complete the disassembly. The operation is simple, and no tools are required for disassembly and installation, which reduces the labor and operation steps of workers and improves the efficiency of installation and disassembly.

[0015] 2. By setting up the lifting component, it is convenient to take the insert block. During disassembly, the fixed rod stops to limit the insert block, and the second spring drives the moving block and the push rod upward through its own elastic force. The push rod pushes the insert block upward for a certain distance, increasing the contact area with the hand, making it convenient for the workpiece personnel to pull out the insert block, further improving the disassembly efficiency.

[0025] In order to reduce the labor and operation steps of workers and improve the efficiency of installation and disassembly, a fixing component 6 is provided to fix the insert block 5. The specific structure is as follows: the fixing component 6 includes a fixing rod 61, which is arranged in the rectangular groove 7. A first spring 62 is provided in the middle of the outer surface of the fixing rod 61. The first spring 62 is used to drive the fixing rod 61 to move to the left. An electromagnet 64 is provided in the right part of the outer surface of the fixing rod 61. The magnetic force of the electromagnet 64 is greater than the elastic force of the first spring 62. The right end of the first spring 62 is fixedly connected with a circular block 63. The circular block 63 is made of iron or stainless steel. The circular block 63 is fixedly sleeved on the fixing rod 61. The fixing rod 61 is located on the left side of the electromagnet 64. A first circular groove 9 is opened in the rectangular groove 7. The first spring 62, the circular block 63 and the electromagnet 64 are all located in the first circular groove 9.
