Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically to an injection mold structure with a quick-change core. Background Technology

[0002] Injection molds are tools used to shape plastic products into desired forms during the manufacturing process. They are typically made of metal (such as steel, aluminum, or copper) and have complex grooves and protrusions inside that determine the final shape of the plastic product. Injection molds are a fundamental component of plastic product manufacturing, helping manufacturers quickly and efficiently transform plastic raw materials into finished products.

[0003] When using injection molds, the mold core needs to be installed. In the process of using existing injection molds, the mold core is usually installed and positioned through the positioning holes inside the mold base. However, the positioning holes cannot vertically limit the mold core. The mold base shaking will cause the mold core to slide up and down inside the mold base, affecting the molding effect. Moreover, after long-term use, injection material will adhere to the gap between the mold core and the mold base, which can easily cause the mold core to stick to the mold base, making it difficult to disassemble and replace the mold core.

[0004] Therefore, it is necessary to provide a new injection mold structure with quick-change cores to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an injection mold structure for quick core replacement, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change injection mold structure, including a mold base, and further comprising:

[0007] A mold core is disposed inside the mold base. A mounting base is fixedly connected to the bottom of the mold core. A fixing base for mounting the mounting base is fixedly connected to the bottom of the inner cavity of the mold base. A guide rod is slidably connected to the inner wall of the fixing base. A baffle is fixedly connected to the inner wall of the guide rod. A support base is fixedly connected to the top of the fixing base. A first spring for limiting the guide rod is fixedly connected to the inner wall of the support base. A limiting block for limiting the mounting base is rotatably connected to the inner wall of the support base. An air hood is disposed inside the mold base. An air outlet is disposed on the top of the air hood.

[0008] Preferably, a cylinder is installed on one side of the fixed base, and the piston rod of the cylinder is fixedly connected to a guide rail.

[0009] Preferably, a guide block is fixedly connected to one end of the guide rail, and the outer side of the guide block is slidably connected to the inner wall of the fixed seat.

[0010] Preferably, a limiting frame for limiting the position of the mounting base is fixed to the top of the fixed base, and a guide rod is slidably connected to the inner wall of the fixed base.

[0011] Preferably, a limiting plate is fixedly connected to the bottom of the guide rod, and a second spring is fixedly connected to the bottom of the limiting plate.

[0012] Preferably, the inner cavity of the mold base is provided with a guide groove, and a guide plate is fixedly connected to the outer side of the mold core.

[0013] Preferably, an air pump is provided on the outside of the mold base, and an air outlet pipe is provided at the air outlet end of the air pump.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention uses a guide rod to move a baffle, which in turn pushes a limiting block to rotate, thus limiting the installation of the mold core against the inner wall of the mounting base. A first spring then resets the guide rod and baffle, disengaging the limiting block from the mounting base. A second spring resets the limiting plate and guide rod, which in turn pushes the mounting base to spring up, facilitating the disassembly and replacement of the mold core. An air hood and air outlet clear the gap between the mold core and the mold base, preventing the mold core from sticking to the inner wall of the mold base due to the adhesion of injection molding material.

[0023] A cylinder 12 is installed on one side of the fixed base 4. The piston rod of the cylinder 12 is fixedly connected to a guide rail 13. The outer side of the guide rail 13 is slidably connected to the inner wall of the guide rod 5. A guide wheel is provided inside the guide rail 13 to avoid the guide rod 5 from getting stuck. A guide block 14 is fixedly connected to one end of the guide rail 13. The outer side of the guide block 14 is slidably connected to the inner wall of the fixed base 4. A limit frame 15 is fixedly fixed on the top of the fixed base 4. The limit frame 15 can limit the mounting base 3. A guide rod 16 is slidably connected to the inner wall of the fixed base 4. A limit plate 17 is fixedly connected to the bottom of the guide rod 16. A second spring 18 is fixedly connected to the bottom of the limit plate 17. A guide groove 19 is provided in the inner cavity of the mold base 1. A guide plate 20 is fixedly connected to the outer side of the mold core 2. The outer side of the guide plate 20 is engaged with the inner wall of the guide groove 19.

[0024] An air pump 21 is provided on the outside of the mold base 1. An air outlet pipe 22 is provided at the air outlet end of the air pump 21. One end of the air outlet pipe 22 is connected to the outside of the air outlet shroud 10. When the air pump 21 is started, the gap between the mold core 2 and the mold base 1 is cleared through the air outlet shroud 10 and the air outlet head 11, so as to avoid the problem of the mold core 2 sticking due to the injection molding material adhering to the inner wall of the mold base 1.

[0025] Working principle: When installing the mold core 2, the guide plate 20 is inserted into the guide groove 19, and the mounting base 3 is secured to the top of the fixed base 4. The mounting base 3 is limited by the limiting bracket 15. The mounting base 3 drives the guide rod 16 and the limiting plate 17 to slide inside the fixed base 4, causing the second spring 18 to retract. The starting cylinder 12 pushes the guide rail 13 to move, causing the guide block 14 to slide inside the fixed base 4. The guide rail 13 pushes the guide rod 5 to move upward. The guide rail 13 is equipped with a guide wheel to prevent the guide rod 5 from getting stuck, allowing the guide rod 5 to slide inside the support base 7, causing the first spring 8 to retract. The movement of the guide rod 5 drives the baffle 6 to move, blocking... Plate 6 pushes the limiting block 9 to rotate, so that the limiting block 9 limits the inner wall of the mounting base 3, thereby limiting the installation of the mold core 2. When the mold core 2 needs to be replaced, the cylinder 12 pulls the guide rail 13 and guide block 14 to reset. The first spring 8 drives the guide rod 5 and baffle 6 to reset, so that the limiting block 9 is disengaged from the mounting base 3. The second spring 18 drives the limiting plate 17 and guide rod 16 to reset. The guide rod 16 pushes the mounting base 3 to spring up, so as to facilitate the disassembly and replacement of the mold core 2. The air pump 21 is started, and the gap between the mold core 2 and the mold base 1 is cleared through the air hood 10 and the air head 11 to prevent the injection molding material from adhering to the inner wall of the mold base 1 and causing the mold core 2 to stick.
