Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and specifically relates to an assembly structure for injection molds. Background Technology

[0002] In the field of injection molding technology, injection molds are core process equipment, and their structural design directly affects production efficiency, product quality, and ease of maintenance. The mold core installation structure of traditional injection molds mostly relies on bolt-type fixing. Although this installation method can ensure the stability of the mold core during the injection process to a certain extent, its limitations are becoming increasingly prominent as the manufacturing industry continues to increase its requirements for production efficiency, flexibility, and cost control.

[0003] Traditional bolt-mounted structures require tightening multiple bolts one by one to install the mold core during injection mold assembly. This process is not only time-consuming and labor-intensive, but also severely restricts the flexibility and response speed of the injection molding production line, especially in mass production or when frequent mold core replacement is required. Furthermore, the disassembly and assembly of the mold core and the mold body are also costly during the later maintenance of the injection mold or when the mold core is upgraded or replaced. The disassembly and assembly process is not only cumbersome, but also prone to difficulties due to bolt corrosion, damage, or loss. Therefore, this utility model proposes an assembly structure for injection molds. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1 to 4 This is the first embodiment of the present invention, which provides a technical solution: an assembly structure for an injection mold, comprising...

[0026] An installation groove 41 is provided on the bottom surface of the mold body 4 for mounting the mold core 3;

[0027] The quick-release structure between the mold core 3 and the mold body 4 includes side grooves 11 on both sides of the mold body 4, a limiting strip 12 installed inside the side groove 11, a limiting insert 15 rotatably installed on the side of the limiting strip 12, a limiting slot 16 on both sides of the mold core 3, and a strip groove 14 on the upper wall of the side groove 11 corresponding to the limiting strip 12. A side hole is provided between the side groove 11 and the mounting groove 41 for the limiting insert 15 to pass through. The inner end of the limiting insert 15 passes through the side hole into the limiting slot 16, which can stably limit the mold core 3. The top end of the limiting strip 12 is screwed into the strip groove 14, so that the limiting strip 12 and the limiting insert 15 are vertically aligned. The vertical direction is stably limited, ensuring that the inner end of the limiting plug 15 is stably inserted into the limiting slot 16 during daily use, thus ensuring the installation stability of the mold core 3. In actual assembly of the mold core 3 with the mold body 4, the mold core 3 is first pushed into the mounting groove 41, and then the limiting strip 12 is horizontally pushed into the side groove 11, so that the inner end of the limiting plug 15 can pass through the side hole into the limiting slot 16, which can quickly limit the mold core 3. Finally, the top end of the limiting strip 12 is screwed into the strip groove 14, which can quickly limit the limiting strip 12 and the limiting plug 15 in the vertical direction, completing the quick assembly of the mold core 3 and the mold body 4, and also facilitating the quick disassembly and replacement of the mold core 3 in the future.

[0028] And a sealing component 2 located on the bottom surface of the mold body 4 and outside the mold core 3.

[0029] In this embodiment, preferably, the outer end surface of the limiting insert 15 is fixed with a shaft block 13, and the bottom end of the limiting clip 12 is rotatably sleeved on the shaft block 13, so that the limiting clip 12 can be smoothly rotatably connected with the limiting insert 15, and also so that after the inner end of the limiting insert 15 is inserted into the limiting slot 16, the operator can smoothly rotate the limiting clip 12 in the side groove 11.

[0030] In this embodiment, preferably, the top end of the limiting strip 12 has an inner groove 121, and the inner groove 121 is equipped with a spring 122 and a telescopic locking bead 123. The side wall of the strip-shaped groove 14 has a circular groove 141 corresponding to the telescopic locking bead 123. The telescopic locking bead 123 is movably installed in the inner groove 121 by the spring 122, and the end of the telescopic locking bead 123 pops out into the circular groove 141. When the top end of the limiting strip 12 is screwed into the strip-shaped groove 14, the end of the telescopic locking bead 123 will be pushed into the circular groove 141 by the spring 122, thereby achieving the limiting strip 12's... The locking and limiting mechanism 2 ensures that the top of the limiting strip 12 will not unscrew out of the strip groove 14 during daily use. When it is necessary to separate the mold core 3 from the mold body 4, simply push the limiting strip 12 forcefully so that the end of the telescopic ball 123 is squeezed into the inner groove 121. Then the top of the limiting strip 12 can be easily unscrewed from the strip groove 14. At this time, the limiting strip 12 can be moved to the side to successfully remove the limiting insert 15. Without the limiting insert 15, the mold core 3 can be directly removed from the mounting groove 41, and the mold core 3 can be quickly disassembled and replaced.

[0031] In this embodiment, preferably, one end of the spring 122 is fixed to the inner wall of the inner groove 121, and the other end of the spring 122 is fixed to the telescopic bead 123.

[0032] In this embodiment, preferably, the top side of the limiting strip 12 is provided with a pop-out hole communicating with the inner groove 121, and the pop-out hole is adapted to the telescopic bead 123, so that the end of the telescopic bead 123 can pop out smoothly.

[0033] In this embodiment, preferably, the sealing component 2 includes a U-shaped bottom groove 21 formed on the bottom surface of the mold body 4 and located at the edge of the mounting groove 41. A U-shaped rubber seat 22 is installed in the U-shaped bottom groove 21. The inner wall of the U-shaped rubber seat 22 is provided with an integral U-shaped protrusion 23. Both are made of fluororubber and will undergo elastic deformation when squeezed. The surface of the mold core 3 is provided with a U-shaped sealing groove 24 corresponding to the U-shaped protrusion 23. When the mold core 3 is installed into the mounting groove 41, the U-shaped protrusion 23 will be squeezed into the U-shaped sealing groove 24, effectively sealing the bottom surface of the mold core 3 and ensuring the normal completion of the injection molding operation.

[0034] Example 2

[0035] Please see Figures 1 to 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but with the difference that it also includes a sealing component 2 6 disposed on the inner wall of the top of the mounting groove 41 and surrounding the outside of the injection head 5. The sealing component 2 6 includes an annular mounting groove 61 opened on the inner wall of the top of the mounting groove 41, an annular inner rubber seat 62 installed in the annular mounting groove 61, an annular sealing protrusion 63 disposed on the bottom surface of the annular inner rubber seat 62, and an annular sealing groove 64 opened on the top surface of the mold core 3. The annular sealing protrusion 63 is squeezed into the annular sealing groove 64 to ensure the sealing of the contact area between the mold core 3 and the injection head 5.

[0036] In this embodiment, preferably, the annular inner rubber seat 62 and the annular sealing protrusion 63 are an integral structure, both of which are made of fluororubber material. When squeezed, they will undergo elastic deformation. The annular inner rubber seat 62 has an annular cavity inside, so that the annular sealing protrusion 63 has sufficient deformation space when squeezed.
