Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an integral oblique draw structure of a fixed mold. Background Art

[0002] Since the temperature of the fixed mold is relatively high, for the core-pulling structure that needs to pull out multiple core-pulling needles, if the cylinder is not cooled enough or other external environmental factors affect the die-casting production process, it is easy for the core-pulling needles and needle sleeves to get stuck or the needles to break.

[0003] The core-pulling needle sleeve pressure plate and the cylinder core-pulling mechanism of the conventional multi-core-pulling structure are separate. If a fault occurs, the oil cylinder and the oil pipes and cooling accessories around the cylinder must be removed first, and then the core-pulling needle sleeve pressure plate can be removed, and finally the needle sleeve can be removed. The efficiency of disassembly and repair is very low, and for large molds above 2500T, the upper and lower molds are very time-consuming, which seriously affects the production rhythm and reduces production efficiency.

[0004] like Figure 1 As shown, the current mold core pulling structure is a split structure. The oil cylinder and the oil cylinder cooling must be removed first before the core pulling needle sleeve pressure plate can be removed, and finally the core pulling needle sleeve can be removed. This structure is very difficult to disassemble and repair once the core pulling needle and the needle sleeve are stuck or other abnormal conditions occur. Summary of the invention

[0005] In order to solve the problem that the core pulling needle and the needle sleeve are stuck and the broken needle affects the repair time, the utility model provides a fixed mold integral inclined pulling structure. When the core pulling needle and the needle sleeve are stuck, the repair time of the maintenance worker is shortened, thereby reducing the standby time of the die casting machine and improving production efficiency.

[0006] The utility model provides the following technical solutions:

[0007] A fixed mold integral oblique pulling structure includes a core pulling needle sleeve pressure plate, a shaft core main body seat and a core pulling needle assembly. The core pulling needle sleeve pressure plate and the core pulling main body seat are fixed together by screws, and the core pulling needle assembly is installed inside the core pulling main body seat; the core pulling needle assembly includes a core pulling needle fixing block, a core pulling needle pressure plate, a core pulling needle, a spot cooling part, and a cylinder connecting block which are arranged in sequence.

[0008] Furthermore, a core-pulling cylinder is fixedly installed on the top of the shaft core main body seat, and a core-pulling cylinder cooling plate is sleeved on the core-pulling cylinder.

[0009] Furthermore, the core-pulling cylinder is connected to the core-pulling needle through a cylinder connecting block; a spot cooling piece is provided between the core-pulling needle and the cylinder connecting block, and the hollow interior of the spot cooling piece is connected to the core-pulling needle.

[0010] Furthermore, the core pulling needle passes through the core pulling needle pressure plate, the core pulling needle fixing block and the core pulling needle sleeve pressure plate in sequence from top to bottom, and the core pulling needle sleeve pressure plate is fixedly installed on the bottom of the shaft core main body seat.

[0011] Furthermore, the portion of the core pulling needle exposed outside the core pulling body seat is covered with a core pulling needle sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are: by adopting an overall oblique pull-out structure, the oil cylinder and the oil cylinder cooling parts as well as the core pulling needle and the core pulling point cooling parts (including the needle sleeve pressure plate) can be pulled out as a whole, which greatly shortens the time for disassembly and assembly of the mold, shortens the standby time of the die-casting machine, greatly shortens the repair time, has a stable structure, improves production efficiency, and greatly saves maintenance costs.
