[0001] The utility model relates to the technology of mold field, in particular to an injection mold clamping structure. Background Art

[0002] Plastic mold is a key tool for manufacturing plastic products, which is widely used in various molding methods such as compression molding, extrusion molding, injection molding, blow molding and low foaming molding. It consists of concave and convex mold components and auxiliary molding systems, which work in coordination to process plastic products of different shapes and sizes.

[0003] During mass production, the upper mold cavity may deviate from the original position, which may cause the clamp to be too large and affect product production. Utility Model Content

[0004] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide an injection mold clamp structure to solve the problem that the mold may deviate during processing, resulting in an overly large clamp.

[0023] Please refer to Figure 1-5As shown, it shows the specific structure of the preferred first embodiment of the utility model, which is an injection mold clamp structure, including an upper mold 10 and a mold core 20 arranged at the corresponding ends of the upper mold 10 and the lower mold, the mold core 20 is connected to a slide groove 30 arranged on the upper mold 10, and a slidable slide mechanism 40 is connected in the slide groove 30, and the slide mechanism 40 moves with the movement of the slide mechanism 40 to resist the sealing position 21 of the mold core 20, and the slide mechanism 40 is provided with an oil groove 47 near the sealing position 21. Compared with the existing injection mold clamp structure through regular maintenance, or repairing the appearance of the clamp by a mold repair machine. The injection mold clamp structure can reduce the frequency of mold repair through the slide mechanism 40, avoid the risk of excessive clamping caused by the slide swing during mass production, thereby improving the stability of mass production. When the slide mechanism 40 moves, the oil in the oil groove 47 reduces the friction between the mold parts to ensure that its movement is smoother, thereby extending the service life of the mold.

[0024] Specifically, the mold core 20 is detachably installed on the opposite surfaces of the upper mold 10 and the lower mold, the mold cavity of the mold is located in the middle of the mold core 20, the sliding groove 30 is located next to the mold cavity, and the sliding mechanism 40 slides in the sliding groove 30 and contacts with the sealing position 21 of the mold cavity. The products in the undercut, sunken and other positions in the mold cavity are taken out by moving the sliding mechanism 40.

[0025] like Figure 2 As shown, the slide mechanism 40 includes a first shovel base 41 that can move in the inner cavity of the slide groove 30, and the first shovel base 41 contacts the glue sealing position 21 as it moves. The first shovel base 41 in the slide mechanism 40 slides in the slide groove 30, and as the first shovel base 41 moves in the slide groove 30, the first shovel base 41 contacts the glue sealing position 21 to form a mold cavity, or the first shovel base 41 is away from the glue sealing position 21, so that the user can take out the inverted or sunken products in the mold cavity.

[0026] like Figure 2 As shown, the slide mechanism 40 also includes dovetail grooves 42 disposed on opposite side walls of the slide groove 30, and a slide bar 43 sliding in the inner cavity of the dovetail groove 42, and the slide bar 43 is connected to the side wall of the first shovel base 41. By installing the slide bars 43 on both sides of the first shovel base 41 and inserting the slide bars 43 into the dovetail grooves 42, the movement of the first shovel base 41 is performed along the dovetail grooves 42 through the slide bars 43, which is smoother and more stable, so as to reduce the deflection during the slide.

[0027] like Figure 3As shown, the sliding mechanism 40 also includes a central guide rail 44 disposed at the bottom of the sliding groove 30, and a clamping groove 411 is disposed at the lower part of the first shovel base 41, and the central guide rail 44 is inserted and slidably engaged with the clamping groove 411. By inserting the clamping groove 411 disposed at the bottom of the first shovel base 41 with the central guide rail 44 fixed at the middle of the inner cavity of the sliding groove 30, when the first shovel base 41 moves, it moves along the central guide rail 44 through the clamping groove 411, so that the movement of the first shovel base 41 is more stable. In addition, during the processing, the first shovel base 41 will not produce sliding deviation due to air pressure resistance.

[0028] like Figure 4 As shown, for example, a removable stopper 46 is provided in a concave placement groove 45 on the upper part of the first shovel base 41, and one side of the stopper 46 is connected to the sealing position 21. By opening the placement groove 45 on the first shovel base 41, one side of the stopper 46 placed in the placement groove 45 extends into the sealing position 21, and the shape of the sealing position 21 can be adjusted by moving to adapt to the processing of different products.

[0029] like Figure 5 As shown, illustratively, the side of the first shovel base 41 away from the sealing position 21 is connected to the second shovel base 50, and the opposite surfaces of the first shovel base 41 and the second shovel base 50 are plugged into each other through the protrusion 60 and the socket 70. The second shovel base 50 is plugged into the protrusion 60 on the first shovel base 41 through the socket 70 to limit the moving length of the first shovel base 41.

[0030] The second shovel base 50 is provided with a connection port 80 penetrating the second shovel base 50, a limiting block 90 is inserted into the connection port 80, and one end of the limiting block 90 protrudes from the outside of the connection port 80. The middle of the second shovel base 50 is provided with a connection port 80 penetrating the upper and lower ends, and the limiting block 90 inserted into the connection port 80 limits the movement of the second shovel base 50, thereby limiting the movement of the first shovel base 41 and supporting the first shovel base 41.

[0031] The other end of the limiting block 90 extends into the upper mold 10 .

[0032] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
