Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a slider locking mechanism of an injection mold. Background Art

[0002] The slider locking mechanism of the injection mold is a mechanical device used to fix the position of the slider in the mold. The slider is responsible for forming the moving parts of the mold during the injection molding process, such as side core pulling or slider molding. The function of the slider locking mechanism is to keep the slider in the correct position during the injection molding process, prevent displacement caused by injection pressure, and ensure the dimensional accuracy and surface quality of the molded product.

[0003] The invention discloses an injection mold core-pulling slider mechanism with the publication number CN102514152A, which belongs to the field of injection molds and includes a movable slider insert, a hook, a slider seat, a slider pressure plate, a slider shovel base, an inclined guide column and a spring. The spring is placed in the inner hole of the slider seat groove, and the spring is fixed in the inner hole of the groove by the hook. The hook is placed in the grooves on both sides of the slider seat and connected with the slider seat. A hook groove is provided at the rear of the movable slider insert, and the hook is buckled on the hook groove to connect the slider seat and the movable slider insert into one body. The slider seat guides and slides in the slider pressure plate, the inclined guide column is inserted in the slider seat, and the slider shovel base is locked with the matching surface of the slider seat. The beneficial effect is that the mechanism of the hook and the movable slider insert is adopted. For inserts of different shapes, just loosen the hook and replace the movable slider insert of the corresponding shape, and then buckle the movable slider insert by the hook, which is convenient for workers to operate and place metal inserts, and the disassembly and assembly are flexible, and the operation is simple and fast, which improves work efficiency.

[0004] As shown in the above-mentioned equipment, the slider locking mechanism of the injection mold of the prior art adopts a locking mechanism of the matching surface of the slider shovel base and the slider seat. During part of the movement process of the mold injection, it will be impacted. The vibration generated by the impact force will continuously affect the mold and its locking mechanism, thereby shortening the service life of the mold and its locking mechanism.

Detailed Embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figures 1-5 , the present invention provides the following two technical solutions:

[0027] The first embodiment: A slider locking mechanism of an injection mold, comprising:

[0028] A chute plate 1, and the inner wall of the chute plate 1 is provided with a slider locking structure of the injection mold;

[0029] The fixed locking mechanism 3 is arranged on the inner wall of the chute plate 1 and is used to fixedly lock the slider of the injection mold.

[0030] The separation assisting component 6 is arranged at one end of the fixed locking mechanism 3 and is used to quickly separate the slider of the injection mold by the fixed locking mechanism 3.

[0031] The outer wall of the chute plate 1 is fixedly connected with a ramp plate 2, and a hinge hole 7 is formed in the outer wall of the chute plate 1.

[0032] An inspection plate 8 is arranged at the top end of the mounting post 33, and mounting holes are fixedly connected to the outer wall of the inspection plate 8.

[0033] The chute plate 1 is connected with a slider body 4 through the fixed locking mechanism 3. A slide plate 5 is fixedly connected to the outer wall of the slider body 4, and the slide plate 5 is slidably connected in the chute plate 1.

[0034] The fixed locking mechanism 3 includes a mounting plate 31 which is fixedly installed on the inner wall of the chute plate 1. A hinge box 32 is fixedly installed at the top end of the mounting plate 31. A mounting post 33 is fixedly installed inside the hinge box 32. A connecting sleeve 34 is fixedly installed inside the hinge box 32. A locking component 35 is arranged at one end of the hinge box 32.

[0035] The locking component 35 includes a mounting box 351 which is fixedly installed at one end of the hinge box 32. A slide rail A352 is fixedly installed on the inner wall of the mounting box 351. A limiting block 353 is slidably connected to the outer wall of the slide rail A352. A damping limiting plate 354 is fixedly installed inside the mounting box 351. A return spring 355 is fixedly connected to the outer wall of the damping limiting plate 354. The other end of the return spring 355 is fixedly connected to a locking seat 356. An insertion slot 357 is formed in the outer wall of the mounting box 351.

[0036] The slider locking mechanism of this injection mold is provided with a fixed locking mechanism 3. The elastic force of the spring can provide an additional locking force when the mold is closed, reducing the displacement of the slider caused by changes in injection pressure or other external forces, thereby improving the overall stability of the mold and the product quality. The use of springs can reduce mechanical wear because they absorb part of the impact force during the movement process, helping to extend the service life of the mold and its locking mechanism.

[0037] The second implementation mode, the main difference from the first implementation mode is that: the separation assisting component 6 includes a connection box 61 which is fixedly installed at the bottom end of the mounting plate 31. An electric push rod 62 is fixedly connected to the inner wall of the connection box 61. One end of the electric push rod 62 is fixedly connected to a sliding seat 63. A slide rail B66 is slidably connected to the bottom end of the sliding seat 63. A connecting plate 64 is fixedly connected to the top end of the sliding seat 63. A pushing post 65 is fixedly connected to the top end of the connecting plate 64.

[0038] The slider locking mechanism of the injection mold is provided with a separation assisting component 6, which can promote the rapid separation of the fixed locking mechanism 3 from the slider body 4, prevent the slider body 4 from being stuck in the fixed locking mechanism 3, and reduce mold damage or production interruption caused by friction or jamming.

[0039] Meanwhile, the content not described in detail in this specification belongs to the prior art well-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] Before mold injection, as other components of the injection molding machine gradually push the slider body 4 to align with the fixed locking mechanism 3, as the slider body 4 gradually slides, the clamping block connected to one end thereof also gradually moves. When the clamping block moves to a certain extent, it will squeeze the locking seat 356, and thus squeeze the return spring 355 connected to one end of the locking seat 356. As the two locking seats 356 move outward and continuously squeeze and deform the two return springs 355 to a certain extent, the clamping block can slide into the inner wall of the locking seat 356 and be fixedly clamped. When the impact force generated during mold injection occurs, the vibration generated by the impact force can be gradually consumed under the cooperation of the return spring 355 and the damping limiting plate 354 to reduce the wear of the machine, and thus extend the service life of the mold and its locking mechanism. When the injection molding is completed and the slider body 4 needs to be separated, the electric push rod 62 can be contracted to drive the sliding seat 63 to slide on the slide rail B66, and then drive the connecting plate 64 and the pushing column 65 to move. As the pushing column 65 gradually moves through the insertion slot 357 and pushes the limiting block 353 to slide on the slide rail A352, as the limiting block 353 gradually slides, it will squeeze the locking seat 356 to move. When the locking seat 356 moves to a certain extent, the slider body 4 can slide out and separate from the chute plate 1.
