[0001] This utility model relates to the technical field of mold components and devices, and in particular to a quick mold change locking mechanism for injection molds of car navigation panel. Background Technology

[0002] In the automotive parts manufacturing sector, the production efficiency and quality of car navigation panels, as important interior components, are crucial to the overall vehicle manufacturing process.

[0003] Currently, the mold changing process for traditional car navigation panel injection molds usually relies on manual operation. When changing molds, a connector is installed on the upper and lower molds respectively. Then, the upper and lower molds are brought close together and finally connected by bolts. This process is quite cumbersome, requiring the connector to be installed with bolts first, and then manually connected, which affects work efficiency and has certain shortcomings.

[0004] Therefore, a quick mold change locking mechanism for injection molds of car navigation panel is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a quick mold changing and locking mechanism for injection molds of car navigation panel.

A sliding groove is provided on the end of the insertion rod away from the locking block. The limiting block is slidably connected in the sliding groove, and an inclined surface is provided on the limiting block. Through the contact between the inclined surface and the bottom of the locking block, the limiting block can slide into the sliding groove. Subsequently, the limiting block will enter the limiting groove to restrict the insertion rod.

[0015] To facilitate reset, preferably, multiple sets of springs are connected inside the slide groove, and the other end of each spring is connected to a limiting block.

[0016] To further improve stability, preferably, one end of the electromagnet is located in the limiting groove, and the limiting block is fixed by magnetic attraction.

[0017] To facilitate the separation of the locking blocks, preferably, a top block is slidably connected to the lower part of the locking block. One end of the top block is located in the limiting groove, and an mounting plate is installed on the other end of the top block. Multiple sets of return springs are connected to the mounting plate, and the other end of the return spring is fixedly connected to the lower part of the locking block. By moving the top block, the top block can squeeze the limiting block and retract it into the sliding groove.

[0018] To facilitate the installation of the locking block on the mold using bolts, preferably, mounting blocks are fixedly connected to both the upper and lower parts of the locking block, allowing the upper and lower parts of the locking block to be installed on the injection mold via these mounting blocks.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example:

[0029] Reference Figure 1-5A quick mold change locking mechanism for an injection mold of a car navigation panel includes: an upper locking block 1, installed on the upper mold of the injection mold; a lower locking block 2, installed on the lower mold of the injection mold; an insert rod 101, fixedly connected to the upper locking block 1; a slot 201, disposed on the lower locking block 2, with the insert rod 101 matching the slot 201; an electromagnet 203, fixedly connected inside the slot 201, used to magnetically attract the insert rod 101; and an auxiliary limiting component for assisting in limiting the insert rod 101. The auxiliary limiting component includes a limiting block 102 and a limiting groove 202. The limiting groove 202 is disposed at the bottom of the slot 201. A sliding groove is provided on the end of the insert rod 101 away from the upper locking block 1. The limiting block 102 is slidably connected in the sliding groove, and an inclined surface is provided on the limiting block 102. Through the contact between the inclined surface and the lower locking block 2, the limiting block 102 can slide and retract. The insertion rod 101 is inserted into the slide groove, and then the limiting block 102 will enter the limiting groove 202 to restrict the insertion rod 101. Multiple sets of springs 103 are connected in the slide groove, and the other end of the springs 103 is connected to the limiting block 102. One end of the electromagnet 203 is located in the limiting groove 202 and the limiting block 102 is fixed by magnetic attraction. A top block 204 is slidably connected to the lower locking block 2. One end of the top block 204 is located in the limiting groove 202, and an installation plate is installed on the other end of the top block 204. Multiple sets of return springs 205 are connected to the installation plate. The other end of the return springs 205 is fixedly connected to the lower locking block 2. By moving the top block 204, the top block 204 can squeeze the limiting block 102 and make it retract into the slide groove. Both the upper locking block 1 and the lower locking block 2 are fixedly connected to the installation block 3. The upper locking block 1 and the lower locking block 2 can be installed on the injection mold by the installation block 3 and the bolt.

[0030] When in use, the locking block 1 and the locking block 2 are respectively installed on the upper and lower molds of the injection mold used for car navigation system injection by bolts. The upper and lower molds should have bolt holes for installing the locking mechanism.

[0031] Then, the hydraulic device on the machine tool gradually moves the upper mold closer to the lower mold, causing them to fit together. At this point, the insert rod 101 will be inserted into the slot 201. Simultaneously, influenced by the inclined surface at the bottom of the limiting block 102, the limiting block 102 will compress the spring 103, causing it to retract into the slide groove until it is inserted to the bottom. At this point, under the action of the spring 103, the limiting block 102 will enter the limiting groove 202, thus serving as an auxiliary limiting device. Then, the electromagnet 203 is energized to restrict the insert rod 101 and the limiting block 102. The upper and lower molds will fit together tightly, and then the injection mold can be disassembled from the machine tool. Then, the new injection mold is installed, and finally the old injection mold is moved to the storage location by a lifting device or forklift. The electromagnet 203 is then de-energized. If maintenance is required later, the mold is separated. At this time, the mounting plates on the top block 204 can be pressed inward with fingers to make the top block 204 press the limiting block 102, thereby causing the limiting block 102 to enter the slide groove. Then, the upper and lower molds can be separated by a lifting device or other auxiliary devices, and then the mold can be maintained.

[0032] When it is finally needed to be used again, it can be attracted again by electromagnet 203, then transported, and finally installed on the machine tool.

[0033] This utility model inserts the insertion rod 101 into the slot 201, uses an auxiliary limiting component to restrict the insertion rod 101, and uses an electromagnet 203 to attract and fix the insertion rod 101 in the lower locking block 2, thereby achieving a quick connection between the upper locking block 1 and the lower locking block 2, which facilitates the quick replacement of the injection mold.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
