[0030] The movable mold 1 and the fixed mold 2 are connected by setting a connecting mechanism 4, and the connecting block 41 in the movable mold 1 is connected to the side core pull 44 through the inclined slide groove 43, so that when the movable mold 1 is separated from the fixed mold 2, the connecting block 41 pulls the side core pull 44, and the insertion rod 46 on the surface of the side core pull 44 is pulled out from the mold cavity 47, so that the core 510 in the mold cavity 47 loses the extrusion of the insertion rod 46.

[0031] The driving mechanism 5 is provided with a cylinder 51, and the outer wall surface of the fixed mold 2 is fixedly connected to a mounting plate 52, and the end surfaces of the two adjacent mounting plates 52 are fixedly connected to a fixing seat 521. One end surface of the cylinder 51 is fixedly connected to the surface of the fixing seat 521, and the piston end of the cylinder 51 is movably plugged into the surface of the fixing seat 521. The mounting seat 415 is used to install and fix the cylinder 51, so that it is convenient for the cylinder 51 to act on the fixed mold 2. The piston end surface of the cylinder 51 is fixedly connected to a connecting plate 53, and the surface of the connecting plate 53 is fixedly connected to a rack 54. A movable groove 55 is provided on the surface of the fixed mold 2, and the end of the rack 54 is slidably connected to the inner wall of the movable groove 55.

[0032] The cam 58 is engaged with the gear 59 on the upper end of the mold 2 and the lower end of the mold 2 is engaged with the gear 59 on the lower end.

[0033] By installing a driving mechanism 5 on the surface of the fixed mold 2, the cylinder 51 of the driving mechanism 5 is used to drive the core 510 on the surface of the fixed mold 2 to rotate, and the core 510 rotates in the mold cavity 47. The rotation reduces the friction between the surface of the core 510 and the inner wall of the extrusion ring 49 and the inner wall of the mold cavity 47, so that the driving device has the characteristic of facilitating the separation of the movable mold 1 from the fixed mold 2.

[0034] Working principle:

[0035] When in use, the melted raw material is injected into the casting hole, and the raw material is formed in the fixed mold 2 and the movable mold 1. After waiting for the raw material to be formed, the movable mold 1 is pulled outward. When the movable mold 1 is pulled outward, the connecting block 41 pulls the inner wall of the limiting groove 45 on the surface of the side core pulling 44 through the inclined slide groove 43, and one end of the side core pulling 44 slides along the incision groove 42. When the side core pulling 44 slides, it drives the insertion rod 46 on the surface to be pulled out from the mold cavity 47, and the core 510 in the mold cavity 47 loses the extrusion of the insertion rod 46. At the same time, when the side core pulling 44 is pulled by the connecting block 41, the side core pulling 44 pulls the slider 412 through the inclined push grass and the inclined block 413, and the slider 412 pulls the extrusion block 410 through the side withdrawal rod 411. The surface of the extrusion block 410 loses the extrusion force of the side withdrawal rod 411, and the extrusion ring 49 no longer squeezes the core 510.

[0036] Start the drive motor, which drives the rack 54 to extend into the movable groove 55. At the same time, the surface of the rack 54 drives the drive gear 58 to rotate. The drive gear 58 drives the connecting gear 59 to rotate together through the rotating shaft 57. The connecting gear 59 drives the core 510 to rotate through the transmission gear 511. When the core 510 rotates, the friction between the inner wall of the extrusion ring 49 and the inner wall of the mold cavity 47 is reduced, and as the movable mold 1 moves, the core 510 is pulled out of the extrusion ring 49 and the mold cavity 47, and the cast product is taken out.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
