Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold with a slider structure. Background Art

[0002] In a die-casting mold with a slider structure, the slider structure typically consists of a slider core and a slider seat. The slider seat is movably connected to the die frame of the die-casting mold and movably positioned within the mold cavity of the mold body, carrying the slider core. In this die-casting mold, the slider core is primarily used to shape the casting contour, perform core pulling to form internal cavities or detailed structures, and separate the castings.

[0003] Under normal circumstances, when the slider core and the mold core are in place, the edges of the slider seat and the mold core are fit and locked. However, during formal mass production, with continuous production and without the condition of cleaning the lower mold, aluminum chips generated by the product during the multi-mold production process will accumulate at the lock point between the slider seat and the mold core edge, resulting in the slider core and the mold core not being able to fit in place, which has a certain degree of impact on the manufacturing quality of the product. Once they are not in place, a gap will be generated between the slider seat and the edge of the mold core. In the subsequent die-casting process, the entry of molten aluminum will produce a certain amount of flash in this gap. In the subsequent production process, more and more aluminum chips will accumulate, resulting in the slider core continuously not being able to fit in place, and the gap will continue to increase, resulting in the production of flying materials in the later production process. These flying materials will damage the mold core and the slider core to a certain extent, causing the matching mold core to collapse and dent, and eventually causing the mold to fail to seal, resulting in the mold being unable to produce continuously, requiring lower mold repair, affecting production delivery, and increasing factory costs. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a die-casting mold with a simple structure and a slider structure, so as to solve the above technical problems.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A die-casting mold with a slider structure comprises a mold body, the mold body comprises a mold frame and a mold core, the mold frame comprises a fixed mold frame and a movable mold frame, the mold core comprises a fixed mold core and a movable mold core, the fixed mold core is arranged in the fixed mold frame, and the movable mold core is arranged in the movable mold frame, and when the fixed mold frame and the movable mold frame are closed, a mold cavity is formed between the movable mold core and the fixed mold core, a slider core is provided in the mold body which can move forward and backward, the rear end of the slider core is connected to the slider seat, the rear end face of the slider core is abutted against the front end face of the slider seat, the front end face of the slider seat is recessed backward and provided with a slag discharge groove, the slag discharge groove is connected up and down, and a slag discharge hole is provided on the fixed mold frame. When the slider core is in place, the slag discharge groove is connected to the slag discharge hole in alignment.

[0007] A connecting protrusion is provided in the middle portion of the front end surface of the slider seat, protruding forward. The rear end surface of the slider core is positioned in contact with the front end surface of the connecting protrusion, with a slag discharge groove formed on either side of the connecting protrusion. This simple structure not only ensures a stable connection and installation between the slider core and the slider seat, but also simultaneously forms a slag discharge groove, simplifying manufacturing.

[0008] The slider seat is movably disposed within the mold frame. The mold frame includes a sliding cavity for the slider seat to move forward and backward. Sliding grooves are disposed on the opposing left and right inner walls of the sliding cavity. Sliding blocks are disposed on the left and right sides of the slider seat, respectively, and engage with the sliding grooves. The sliding blocks are embedded in the sliding grooves and can move forward and backward along the grooves. The cooperation between the sliding grooves and the sliding blocks guides the forward and backward movement of the slider core driven by the slider seat.

[0009] The rear end of the slider seat is connected to a driving mechanism for driving the slider seat to move forward and backward. The driving mechanism drives the slider seat to move forward and backward, thereby driving the slider core to move forward and backward.

[0010] The driving mechanism is a driving oil cylinder, which has a simple structure and stable driving.

[0011] Compared with the prior art, the advantages of the present invention are: simple structure, by arranging a slag discharge groove that runs through the slider seat, a slag discharge channel is formed between the slider core and the edge of the mold core through the slag discharge channel after the slider core is closed in place, and the aluminum chips and other deposits generated during the casting process can fall into the slag discharge channel. At the same time, a slag discharge hole that runs through the upper and lower parts is arranged on the fixed mold frame. After the slider core is closed in place, the slag discharge groove is aligned and connected with the slag discharge hole, and the deposits that fall into the slag discharge channel are discharged outward through the slag discharge hole, which effectively solves the problem of the slider core not being able to be closed in place due to the accumulation of aluminum chips, greatly increases the number of molds in continuous production, reduces the lower mold of the mold, and reduces the damage to the mold core surface due to the generation of flash flying materials.
