Detailed Description
Referring to fig. 1 to 3, the utility model discloses a slider structure of loosing core of avoiding collision, including back mould, slider mold insert 1, set up and the big slider 2 on the back mould and the oil hydraulic cylinder that the big slider 2 of drive removed (not show in the picture), be equipped with shaping hole 3 on the big slider 2, be equipped with little slider 4 on the big slider 2, concrete structure lies in: the large sliding block 2 is provided with a T-shaped sliding groove, the small sliding block 4 is a T-shaped sliding block matched with the T-shaped sliding groove, and the T-shaped sliding groove is formed by enclosing a sliding groove 5 on the large sliding block 2 and pressing plates 6 fixed on two sides of the sliding groove 5.
As shown in the figure, a first inclined guide hole 7 and a first inclined guide post 8 matched with the first inclined guide hole 7 are arranged on the small slide block 4, the first inclined guide post 8 is fixedly connected with the front mold, the slide block insert 1 is positioned in the molding hole 3, a second inclined guide hole 9 and a second inclined guide post 10 matched with the second inclined guide hole 9 are arranged on the slide block insert 1, the second inclined guide post 10 is fixedly connected with the small slide block 4, the front mold slides the small slide block 4 through the matching of the first inclined guide post 8 and the first inclined guide hole 7 to drive the second inclined guide post 10 to move when the mold is opened, so that the slide block insert 1 is withdrawn from the molding hole 3 through the matching of the second inclined guide post 10 and the second inclined guide hole 9 to complete the core pulling process of the slide block insert 1, and the angles of the first inclined guide hole 7 and the second inclined guide hole 9 are set to be.
As shown in the figure, the small sliding block 4 is provided with a sliding block limiting groove 11, and the large sliding block 2 is provided with a sliding block limiting block 12 which can be clamped with the groove wall of the sliding block limiting groove 11, so that the small sliding block 4 is prevented from sliding out of the T-shaped sliding groove; the slide block insert 1 is provided with an insert limiting groove 13, and the large slide block 2 is provided with an insert limiting block 14 clamped with the insert limiting groove 13, so that the slide block insert 1 is prevented from dropping out of the forming hole 3.
As shown in the figure, the forming hole 3 is internally provided with a forming boss, the forming hole boss is provided with a containing hole 15, a supporting spring 16 is arranged in the containing hole 15, the slider insert 1 is provided with a spring guide post 17, the supporting spring 16 is sleeved on the spring guide post 17, the top end face of the supporting spring can be extruded with the slider insert 1, by the structure, when the second inclined guide post 10 is separated from the second inclined guide hole 9, the slider insert 1 can be supported by the supporting spring 16, the supporting spring 16 supports the limitation of the insert limiting block 14, the slider insert 1 can be fixed, and the supporting spring 16 can be compressed by the slider insert 1 to reset when the die is closed.
The above structural principle is briefly described as follows: when the mold is opened, the first inclined guide post 8 drives the small slide block 4 to retreat, the second inclined guide post 10 is fixed with the small slide block 4, therefore, the second inclined guide post 10 is driven by the small slide block 4 to retreat, the slide block insert 1 moves upwards under the action of the second inclined guide post 10 to complete the local core-pulling action of the workpiece 18, and the die opening is completed at the same time, then the oil cylinder drives the large slide block 2 to retreat to complete all core-pulling actions, before die assembly is carried out, the oil cylinder drives the large slide block 2 to advance, the large slide block 2 drives the slide block insert 1, the inclined guide post II 10 and the small slide block 4 to move together, after the large slide block 2 is in place, die assembly is carried out, the front film drives the inclined guide post I8 to be inserted into the inclined guide hole I7, the small slide block 4 and the slide block insert 1 are moved to the right position, because the end part of the inclined guide post I8 is a round head which can be guided and inserted into the inclined guide hole I7, therefore, the point position deviation can not cause the first inclined guide post 8 to collide with the small slide block 4, and even if the sensor fails, the loss of the first inclined guide post 8 and the small slide block 4 is small.
The above detailed description is given to the slider core pulling structure for avoiding collision provided by the embodiment of the present invention, and the specific examples are applied herein to explain the principle and the implementation of the present invention, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
