DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0019] like Figures 1 to 3 As shown, the utility model provides a mold core clamping and positioning fixture, including a main body 1, a mold core 2 and a plurality of clamping modules 3, the clamping modules 3 are used to fix the mold core 2 to the main body 1, and a plurality of pressing parts 4 are provided on the top of the mold core 2, and the clamping modules 3 are used to press down the pressing parts 4 so that the mold core 2 is fixed to the main body 1; the main body 1 is provided with a plurality of positioning pins 5, and the mold core 2 is provided with a plurality of positioning holes 6, and the plurality of positioning pins 5 are inserted into the plurality of positioning holes 6 in a one-to-one correspondence.

[0020] Specifically, when installing the mold core 2 to the main body 1, first align the positioning pins 5 with the positioning holes 6, then place the mold core 2 on the main body 1 so that the positioning pins 5 are inserted into the positioning holes 6, and then fix the mold core 2 to the main body 1 by pressing the pressing part 4 down through the clamping module 3 to ensure that the mold core 2 will not move relative to the main body 1, thereby making the processing stable; and when the mold core 2 needs to be replaced, it is only necessary to loosen the clamping module 3 to directly remove the mold core 2 from the main body 1, which is convenient and efficient.

[0021] In this embodiment, the pressing part 4 includes a pressing portion 41 and an insertion portion 42. The pressing portion 41 is arranged at the top of the insertion portion 42. The mold core 2 is provided with an insertion hole 21 for assembling the insertion portion 42. A limiting portion 43 is provided on one side of the pressing portion 41. The limiting portion 43 is used to interfere with the top of the mold core 2 to prevent the pressing portion 41 from being inserted into the insertion portion 42.

[0022] That is, the limiting portion, the pressing portion 41, and the inserting portion 42 form a "7"-shaped structure, and the limiting portion 43 is used to interfere with the main body 1 to prevent the pressing portion 41 from completely entering the inserting hole 21, so that the clamping module 3 can fix the mold core 2 by pressing down the pressing part 4, so that the fixing effect of the mold core 2 is better.

[0023] Specifically, the main body 1 is provided with a support base 11 , and the insertion hole is provided on the support base 11 .

[0024] Specifically, the main body 1 is provided with a plurality of pressing holes, and a plurality of pressing members 4 are provided in a one-to-one correspondence with the pressing holes. The pressing members 4 are configured to be inserted into the pressing holes. Specifically, when the pressing members 4 are pressed, their limiting portions press against the top of the mold core 2 to secure it vertically, while the insertion portions 42 are inserted into the pressing holes to achieve secondary positioning between the main body 1 and the mold core 2, specifically preventing the mold core 2 from moving horizontally relative to the main body 1, thereby ensuring effective positioning.

[0025] In this embodiment, the main body 1 is further provided with a first side push module group 12 and a second side push module group 13. The first side push module group 12 is used to drive the mold core 2 to move along the X axis on the main body 1, and the second side push module group 13 is used to drive the mold core 2 to move along the Y axis on the main body 1.

[0026] The side-push module group is composed of a conventional linear drive module and a contact part. The first side-push module group 12 cooperates with the second side-push module group 13, so that the core 2 positioned by the positioning pin 5 and the positioning hole 6 is slightly offset on the X-axis and the Y-axis. The force applied by the first side-push module group 12 and the second side-push module group 13 is used to keep the position of the core 2 fixed, thereby ensuring the stability of the position of the core 2.

[0027] In this embodiment, the clamping module 3 includes a cylinder 31, a support 32 and a pressing piece 33. The middle part of the pressing piece 33 is rotatably set on the support 32. One end of the pressing piece 33 is rotatably connected to the piston of the cylinder 31, and the other end of the pressing piece 33 is used to press down the pressing piece 4.

[0028] In actual use, the cylinder 31 is mounted on the main body 1, and the support 32 is mounted on the cylinder body of the cylinder 31. That is, the present invention controls the other end of the pressing member 33 to flip by extending and retracting the piston rod of the cylinder 31, thereby achieving the effect of pressing down and releasing the pressing member 4. With this simple action, the mold core 2 can be quickly fixed and released on the main body 1, which is simple and efficient.

[0029] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
