Description

Technical Field

[0001] This utility model relates to the field of hot runner mold technology, specifically an L-shaped hot nozzle injection mold. Background Technology

[0002] Hot runner molds, also known as hot nozzle injection molds, are molds that use heating devices to prevent the melt in the runner from solidifying. Because they have a shorter molding cycle than traditional molds and save more raw materials, hot runner molds are widely used in industrialized countries and regions around the world. A hot runner system generally consists of several parts, including hot nozzles, manifolds, temperature control boxes, and accessories.

[0003] Chinese Patent Publication No. CN209971396U discloses a multi-cavity, two-color hot runner system, including an A-type runner plate structure and a B-type runner plate structure. The A-type runner plate structure includes an A-color manifold, on which are provided an A-color injection nozzle and an A-color hot nozzle. The A-color manifold has a protruding end and is generally T-shaped. The B-type runner plate structure has a recessed portion and is generally L-shaped. The improved system operates as two separate systems, A-type and B-type runner plate structures, capable of injection molding two incompatible materials and different colors separately. It can simultaneously injection mold multiple products according to production needs, meeting diverse production requirements and improving work efficiency.

[0004] After the two runner plate structures in the above mold are installed, their positions are fixed, resulting in poor flexibility and an inability to meet the production needs of different products. Therefore, we propose an L-shaped hot nozzle injection mold. Utility Model Content

A first base 2 is installed below the side-injection stage type runner plate structure 1. An electric push rod 3 is installed between the first base 2 and the side-injection stage type runner plate structure 1. A connecting block 5 is installed at the output end of the electric push rod 3. A connecting groove 17 is opened inside the connecting block 5. First limiting holes 15 are opened on both sides of the inner wall of the connecting groove 17. A spring 14 is installed at the front end of the first limiting hole 15. Fixed cylinders 10 are installed on both sides of the electric push rod 3. The internal movement of the fixed cylinders 10 is... A telescopic rod 11 is installed. Limiting connection holes 13 are opened on both sides of the interior of the first base 2. A limiting connection rod 12 passes through the interior of the limiting connection holes 13. A first receiving groove 4 is opened at the rear end of the interior of the first base 2. A second base 8 is installed at the rear end of the first base 2. A second receiving groove 6 is opened at the front end of the interior of the second base 8. A positive injection stage type flow channel plate structure 9 is installed on the top of the second base 8. A connecting plate 7 is installed between the second base 8 and the positive injection stage type flow channel plate structure 9. A second limiting hole 16 is opened inside the connecting plate 7.

[0024] In this implementation scheme: the electric push rod 3, in conjunction with the limiting connecting rod 12 and the limiting connecting hole 13, adjusts the distance between the first base 2 and the second base 8, thereby adjusting the distance between the side-injection stage type runner plate structure 1 and the front-injection stage type runner plate structure 9. By adjusting the distance, the same mold can be adapted to injection molded products of different sizes or structures, such as thin-walled parts and thick-walled parts, reducing the cost of repeated mold development. At the same time, a detachable connecting block 5 and a connecting plate 7 are provided to facilitate the disassembly of the connected first base 2 and the second base 8, making the installation and disassembly operations between the side-injection stage type runner plate structure 1 and the front-injection stage type runner plate structure 9 simple and convenient.

[0025] Furthermore:

[0026] In an optional embodiment, the shape and size of the connecting block 5 partially match the shape and size inside the first receiving groove 4, and the shape and size of the connecting block 5 partially match the shape and size inside the second receiving groove 6.

[0027] In this implementation scheme: when the connecting block 5 is not in use, it can be stored inside the first receiving groove 4 to avoid occupying too much space. When in use, it can be stored in the second receiving groove 6 to ensure that the first base 2 and the second base 8 can fit together.

[0028] Furthermore:

[0029] In an optional embodiment, the connecting plate 7 has a U-shaped structure, and the shape and size of the connecting plate 7 partially match the shape and size inside the connecting groove 17.

[0030] In this embodiment: the U-shaped connecting plate 7 can be inserted into the connecting groove 17 more easily, making it easier to connect the connecting block 5 and the connecting plate 7.

[0031] Furthermore:

[0032] In an optional embodiment, the telescopic rod 11 extends and retracts inside the fixed cylinder 10, passes through the interior of the spring 14, and is elastically connected to the connecting block 5 via the spring 14.

[0033] In this embodiment, the spring 14 can push the telescopic rod 11 into the first limiting hole 15 and the second limiting hole 16 through its own elastic force, making the installation of the connecting block 5 and the connecting plate 7 more convenient.

[0034] Furthermore:

[0035] In an optional embodiment, the telescopic rod 11 passes through the interior of the first limiting hole 15 and the second limiting hole 16 in sequence, and the connecting plate 7 is detachably connected to the connecting groove 17 through the telescopic rod 11, the first limiting hole 15 and the second limiting hole 16.

[0036] In this implementation scheme: when the connecting block 5 moves a certain distance away from the first base 2, the telescopic rod 11 can be withdrawn from the inside of the first limiting hole 15 and the second limiting hole 16, making it easier to disassemble the connecting block 5 and the connecting plate 7.

[0037] Furthermore:

[0038] In an optional embodiment, the limiting connecting rod 12 is fixedly connected to the first base 2, and the shape and size of the limiting connecting rod 12 partially match the shape and size of the inside of the limiting connecting hole 13, so that the limiting connecting rod 12 can move inside the limiting connecting hole 13.

[0039] In this implementation scheme: when the limiting connecting rod 12 is inserted into the limiting connecting hole 13, the connection between the first base 2 and the second base 8 will be more stable.

[0040] Working principle: When using this L-type hot nozzle injection mold, firstly, when installing the side injection stage type runner plate structure 1 on one side of the front injection stage type runner plate structure 9, the controller controls the electric push rod 3 to push the connecting block 5 to move a certain distance away from the first base 2. During this process, the telescopic rod 11 extends out from the inside of the fixed cylinder 10. When the telescopic rod 11 extends to its maximum length, it stops extending, so that the telescopic rod 11 can retract from the inside of the connecting groove 17. Then, the first base 2 is placed at the front end of the second base 8, so that the connecting plate 7 is inserted into the inside of the connecting groove 17. Next, the controller controls the electric push rod 3 to retract, driving the connecting block 5 to move closer to the first base 2. During this process, the limit connection... The connecting rod 12 is inserted into the limiting connection hole 13, and the telescopic rod 11 is inserted into the first limiting hole 15 and the second limiting hole 16 under the elastic force of the spring 14, completing the connection between the side-mounted runner plate structure 1 and the front-mounted runner plate structure 9. At the same time, the distance between the first base 2 and the second base 8 can be adjusted to a suitable distance by the electric push rod 3 to meet the usage requirements. Then, the disassembly operation is the reverse of the installation operation. The side-mounted runner plate structure 1 and the front-mounted runner plate structure 9 are both existing technologies and will not be described in detail here. You can refer to the multi-cavity dual-color mold hot runner system disclosed in Chinese Authorization Announcement No. CN209971396U. This is the working principle of the L-shaped hot nozzle injection mold.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
