Description
Technical Field
The utility model relates to a die-casting die, in particular to a sliding block poking structure in the die-casting die.
Background
For some die-casting products with complex structures, during processing, a sliding block assembly is usually required to be arranged in a die for core pulling, the sliding block assembly generally comprises a sliding block seat, a sliding block core and other parts, and the sliding block assembly is driven to move by an oil cylinder. However, when the oil cylinder drives the slide block assembly, the packing force, the gravity of the slide block assembly and the sliding friction force are needed to bear when the slide block is used for core pulling, so that the volume of the oil cylinder is large, and the core pulling efficiency of the slide block is low.
In order to overcome the problems, some fixed shifting blocks are fixed on the lower end face of the fixed die frame of the die casting die, in the die opening process of the die, the shifting blocks on the fixed die frame shift the sliding block assembly to move for a small distance, so that the sliding block assembly overcomes the tightening force to separate from a product, and then the sliding block assembly is driven to move out by the oil cylinder, at the moment, the oil cylinder only needs to bear the gravity and sliding friction force of the sliding block assembly, so that the volume of the oil cylinder can be reduced, and the core pulling efficiency of the sliding block is improved. However, as the shifting block is in a cantilever state on the fixed die frame and the force born by the shifting block assembly is larger, the shifting block is easy to damage and the service life is shorter; and because the shifting block is positioned at the upper end of the sliding block assembly, the sliding block assembly is unbalanced in stress and unstable in sliding, and the product precision is affected.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a sliding block stirring structure in a die casting die, which enables a stress surface of a sliding block when the sliding block is stirred to be close to the center position of core pulling stress of the sliding block, so that the stress of a sliding block component is balanced, the sliding is stable and reliable, the product forming precision is ensured, and the service life of a stirring block is prolonged.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a slider toggle structure in die casting die, includes slide block seat and shifting block, the one end of slide block seat outwards be provided with upper end open-ended cavity, the cover half frame with the slide block seat on fixed or integrative extension that is provided with on the face relatively, the extension stretch into the cavity in, the shifting block fixed inlay establish the side of extension, the cavity internal fixation be provided with wear-resisting piece, the shifting block with wear-resisting piece pass through the inclined plane cooperation, the shifting block when upwards moving, drive the slide block seat outwards move and make the slider core break away from the product.
Further, the depth of the concave cavity is half of the height of the sliding block seat.
Further, a first mounting cavity with openings on the outer side face and the lower end face is formed in the extension portion, and the shifting block is fixedly embedded in the first mounting cavity.
Further, one outward end of the sliding block seat is provided with a second installation cavity with an opening at the upper end, the side surface of the second installation cavity is communicated with the concave cavity, and the wear-resisting block is fixedly embedded in the second installation cavity.
Further, the wear-resisting block and the shifting block are made of 45# carbon tool steel or P20 and H13 alloy tool steel.
Compared with the prior art, the die-casting die has the advantages that as the concave cavity is formed in the slide block seat, when the die-casting die is assembled, the shifting block and the wear-resisting block are both positioned in the concave cavity, so that the stress surface of the slide block seat when shifted is close to the center of the core-pulling stress of the slide block, the stress of the slide block assembly is balanced, the sliding is stable and reliable, and the product forming precision is ensured; in addition, because the shifting block is integrally embedded in the extending part of the fixed die frame, the wear-resistant block is embedded in the sliding block seat, so that the sliding block seat is stressed stably and reliably when being shifted, the shifting block and the wear-resistant block are protected, and the service lives of the shifting block and the wear-resistant block are prolonged.
