Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with an anti-overflow and anti-sulfurization nozzle structure. Background Art
[0002] An injection mold is a tool used for plastic injection molding. It injects molten plastic material into the mold cavity, where it cools and solidifies to form the desired plastic product. An injection mold typically consists of two parts: a movable mold and a fixed mold. The movable mold is mounted on the injection molding machine's movable platen, while the fixed mold is mounted on the fixed platen. During the injection molding process, the movable and fixed molds close together to form the gating system and the mold cavity. When the mold is opened, the movable and fixed molds separate to facilitate the removal of the plastic product.
[0003] Publication number CN214056276U discloses a main nozzle with an anti-overflow structure. The nozzle comprises a main nozzle body mounted on an injection mold, a main flow channel disposed axially within the main nozzle body, a main nozzle insert disposed at the upper end of the main nozzle body that mates with the nozzle of the injection molding machine, and a nozzle core disposed within the main nozzle body to prevent the outflow of the rubber material. The addition of the nozzle core prevents the outflow of the rubber material from the main nozzle from encountering resistance, slowing its flow rate. Furthermore, upon contact with the outside world, the rubber material within the main nozzle rapidly cools, causing it to solidify.
[0004] As shown in the above-mentioned equipment, the main nozzle of the prior art anti-overflow structure can prevent the rubber from flowing out of the mouth core, but due to the lack of a quick connection mechanism, it may take more time to disassemble, clean or replace the nozzle when it is blocked, which will lead to reduced production efficiency.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See Figure 1-Figure 5 , the utility model provides the following two technical solutions:
[0027] The first embodiment: an injection mold with an anti-overflow and anti-sulfurization nozzle structure, comprising:
[0028] An injection mold body 1, the outer wall of which is provided with a connection mechanism 6 for an anti-overflow and anti-sulfurization nozzle body 5, for quickly connecting and replacing the anti-overflow and anti-sulfurization nozzle body 5 and filtering impurities in the material;
[0029] The anti-overflow and anti-sulfurization nozzle body 5 is arranged on one side of the injection mold body 1 through a connecting mechanism 6 to prevent overflow during the injection molding process;
[0030] The shock absorbing component 4 is provided at the bottom end of the injection mold body 1 and is used for shock absorption during the injection molding process of the equipment;
[0031] An injection groove 7 is formed on the outer wall of the injection mold body 1 .
[0032] The outer wall of the injection mold body 1 is fixedly connected to a connecting seat 2 , and the outer wall of the connecting seat 2 is provided with a hinge groove 3 . The injection mold body 1 is connected to the shock absorbing assembly 4 via the hinge groove 3 .
[0033] The bottom end of the injection mold body 1 is fixedly connected to a movable sleeve 8 , and the bottom end of the movable sleeve 8 is fixedly connected to a mounting seat 9 .
[0034] The connecting mechanism 6 includes a feed pipe 61, which is fixedly installed on the inner wall of the injection mold body 1. One end of the feed pipe 61 is fixedly connected to a connecting sleeve 62. The inner wall of the feed pipe 61 is fixedly connected to a limiting cylinder 64. The outer wall of the limiting cylinder 64 is provided with a reset spring A65. One end of the reset spring A65 is fixedly connected to a sliding ring 66. The inner wall of the limiting cylinder 64 is provided with a filter assembly 68. The outer wall of the connecting sleeve 62 is slidably connected to a push ring 63. The inner wall of the push ring 63 is fixedly connected to a movable block. One end of the movable block is fixedly connected to a reset spring B67. A limiting groove 69 is provided on the inner wall of the connecting sleeve 62. The internal movability of the limiting groove 69 is connected to a limiting valve ball 610.
[0035] The filter assembly 68 includes a limiting ring 684, which is slidably connected to the inner wall of the limiting cylinder 64. The inner wall of the limiting ring 684 is fixedly connected to a placement ring 681. The outer wall of the placement ring 681 is provided with a snap-in groove 682, and the placement ring 681 is snap-in connected to the filter net 683 through the snap-in groove 682.
[0036] The injection mold with an anti-overflow and anti-sulfurization nozzle structure is provided with a connecting mechanism 6. The design of the connecting mechanism 6 enables the nozzle to be quickly and accurately connected to the injection mold, reducing the time for installation and disassembly, thereby improving production efficiency. The filter component 68 can filter impurities in the plastic raw material to a certain extent, preventing the nozzle from being blocked by impurities, thereby improving the quality of the injection molded parts and improving production efficiency.
[0037] The second embodiment is mainly different from the first embodiment in that: the shock absorbing assembly 4 includes a mounting plate 41, the mounting plate 41 is arranged on one side of the injection mold body 1, the bottom end of the mounting plate 41 is fixedly connected to the auxiliary plate 42, the outer wall of the mounting plate 41 is threadedly connected to a threaded bolt 43, the outer wall of the threaded bolt 43 is threadedly connected to a nut 44, the outer wall of the threaded bolt 43 is threadedly connected to a damping plate 45, the bottom end of the damping plate 45 is connected to a pressure spring 46, the other end of the pressure spring 46 is connected to a mounting frame 47, and the bottom end of the mounting frame 47 is fixedly connected to a support base 48.
[0038] The injection mold with an anti-overflow and anti-sulfurization nozzle structure is provided with a shock-absorbing component 4. The shock-absorbing mechanism can effectively reduce the impact of vibration generated during the injection molding process on the mold, thereby reducing mold wear and extending the service life of the mold. At the same time, it can reduce the impact of vibration on the injection molding process, thereby improving product quality and reducing product defects.
[0039] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.
[0040] When the equipment is used for injection molding, vibration will be generated. The force generated by the vibration will spread with the equipment, squeezing the mounting plate 41 to move downward. The downward movement of the mounting plate 41 will drive the auxiliary plate 42 connected to its bottom end to move downward, and will also drive the threaded bolt 43 threadedly connected to its outer wall and the damping plate 45 connected at one end to move downward to squeeze the pressure spring 46. The cooperation of the pressure spring 46 and the damping plate 45 can play a shock-absorbing role. During the injection molding process, excess material will enter the limiting cylinder 64 along the material pipe 61, and then be filtered through the two layers of filter screen 683 in the filter assembly 68 to filter out the impurities therein. After the injection molding is completed, the injection mold body 1 can be opened to take out the injection molded part after waiting for the injection molding. When the anti-overflow and anti-vulcanization nozzle body 5 needs to be replaced or maintained after a period of use, the push ring 63 can be pushed to drive the movable block to move and squeeze the reset spring B67. As the push ring After 63 gradually moves out of the range of the limit groove 69, the limit valve ball 610 is in an active state. At this time, the sliding ring 66 connected to one end of it is reset by the reset spring A65 to move, and the anti-overflow and anti-sulfurization nozzle body 5 can be pushed out. After being pushed out, the anti-overflow and anti-sulfurization nozzle body 5 can be maintained. When it is necessary to replace a new anti-overflow and anti-sulfurization nozzle body 5, the same as above is used to push the push ring 63 to eventually cause the limit valve ball 610 to be in an active state, and then the anti-overflow and anti-sulfurization nozzle body 5 is aligned with the limit cylinder 64 and inserted. As the anti-overflow and anti-sulfurization nozzle body 5 is inserted, the sliding ring 66 and the reset spring A65 are squeezed. When inserted to a certain extent, the push ring 63 is released. As the reset spring B67 moves, the push ring 63 can be driven to reset and cover the limit groove 69, and at the same time, the limit valve ball 610 is squeezed to move inward and get stuck in the slot opened on the outer wall of the anti-overflow and anti-sulfurization nozzle body 5, thereby fixing the anti-overflow and anti-sulfurization nozzle body 5 for installation.
