Specifically, the upper die is provided on the upper die plate 1, and the lower die 3 is provided on the lower die plate 2. The anti-collision thimble die also comprises a side die 5 and a thimble plate 4. The side mold 5 is slidably disposed on the lower mold plate 2, the side mold 5 is disposed on one side of the lower mold 3, and the side mold 5 is provided with a positioning hole 51 adapted to the positioning thimble 42. The ejector plate 4 is arranged below the lower die plate 2, and the ejector plate 4 is provided with an ejector pin 41 and a positioning ejector pin 42. The side mold 5 is movable between a mold position and a mold release position, and the positioning hole 51 is faced to the positioning pin 42 when the side mold 5 is moved to the mold release position.
In the present embodiment, the side mold 5 is capable of sliding in the chute 21, specifically at least through the mold position and the mold release position, and after the casting cools, the side mold 5 is moved from the mold position to the mold release position, thereby effecting the product mold release. After demolding, when the product is re-cast, it is necessary to perform mold clamping, and the side mold 5 is moved from the demolding position to the mold position. When the side die 5 moves to the demoulding position, the positioning holes 51 on the side die 5 are opposite, at the moment, die withdrawal of the side die 5 is completed, the ejector plate 4 ascends, the ejector plate 4 drives the ejector pins 41 and the positioning pins 42 to synchronously ascend, and at the moment, the positioning pins 42 enter the positioning holes 51, so that the side die 5 can be positioned in the ascending and descending processes of the ejector plate 4. When the mold is reset and clamped, the ejector plate 4 and the lifting ejector pin 41 are lowered, and when the side mold 5 moves from the demolding position to the casting mold position, the positioning ejector pin 42 is in a state of being withdrawn from the positioning hole 51, and when the positioning ejector pin 42 is not withdrawn from the positioning hole 51, the side mold 5 is positioned by the positioning ejector pin 42 and cannot move, so that the side mold 5 is prevented from sliding in advance when the lifting ejector pin 41 is not reset sufficiently, and the side mold 5 is prevented from colliding with the lifting ejector pin 41.
Further, as shown in fig. 3 and 4, the lower die plate 2 is provided with a chute 21, and the side die 5 is slidably disposed in the chute 21. By the sliding fit of the side mold 5 and the chute 21, the stability of the movement of the side mold 5 is improved.
In order to further improve the stability of the movement of the side mold 5, as shown in fig. 3 and 4, guide blocks 6 for guiding the sliding of the side mold 5 are provided at both sides of the chute 21. The side mold 5 is slidably arranged between two guide blocks 6.
Mounting grooves extending along the length direction of the sliding groove 21 are formed in two sides of the sliding groove 21, and the lower parts of the guide blocks 6 are embedded into the mounting grooves.
A guide groove 61 is provided on the side of the guide block 6 near the side die 5, and similarly, a guide projection 52 is provided on the surface of the side die 5 near the guide block 6, and when the side die 5 slides in the slide groove 21, the guide projection 52 is fitted into the guide groove 61 and slides in the guide groove 61.
In some embodiments, as shown in fig. 3 and 4, a positioning member 7 for positioning the side mold 5 is provided in the chute 21, and two positioning grooves 53 are provided at the bottom of the side mold 5 corresponding to the mold position and the demolding position, respectively. In this embodiment, by setting the positioning member 7 to position the side mold 5, when the mold position of the side mold 5 is positioned, the side mold 5 can be accurately matched with the lower mold 3, and the matching accuracy is improved. When the demolding position of the side mold 5 is positioned, the alignment precision of the positioning hole 51 and the positioning thimble 42 is improved, and the positioning thimble 42 can enter the positioning hole 51.
Specifically, the positioning member 7 includes an elastic portion and an elongated positioning portion, and the longitudinal direction of the positioning portion is perpendicular to the moving direction of the side mold 5. The length direction of the positioning groove 53 is perpendicular to the moving direction of the side mold 5.
Of course, the positioning member 7 may be a ball screw, an elastic rubber member, or the like.
In some embodiments, as shown in fig. 3 and 4, a limit screw 8 is disposed at the bottom of the chute 21, and the limit screw 8 protrudes out of the chute 21. The bottom of the side die 5 is provided with a travel groove 54 matched with the limit screw 8. In this embodiment, the limit screw 8 and the travel groove 54 are respectively disposed on the chute 21 and the side mold 5, and when in use, the side mold 5 slides in the chute 21, and the limit screw 8 extends into the travel groove 54, so that the travel of the side mold 5 can be limited by the cooperation of the limit screw 8 and the travel groove 54, and the side mold 5 is prevented from slipping from the chute 21.
In some embodiments, the side mold 5 is provided with a first inclined surface inclined to the lower mold 3, specifically, an inclined surface formed by tilting the vertical surface to the lower mold 3 by a certain angle. The upper template 1 is provided with a pressing block 11, and the pressing block 11 is provided with a second inclined plane which is used for being matched and abutted with the first inclined plane. When the side mold 5 is closed, the second inclined surface abuts against the first inclined surface. The side is provided with a first inclined plane, the pressing block 11 is arranged on a second inclined plane, the pressing block 11 descends along with the upper die plate 1 during die assembly, and the second inclined plane of the pressing block 11 abuts against the first inclined plane, so that the side die 5 is clamped and moves towards a casting die position.
Further, as shown in fig. 2 and 3, the upper die plate 1 is further provided with a guide post 12 arranged obliquely, and the guide post 12 is inclined in a direction away from the upper die. The side mold 5 is provided with a guide hole 55 matched with the guide post 12.
