A die-casting mold core-pulling cooling device

Abstract

The invention relates to the field of mold equipment, in particular to a core-pulling cooling device for die-casting molds, which includes a moving mechanism. Fixing mechanism, the fixing mechanism includes a fixing component and an adjusting component, the adjusting component is installed at the end of the fixing component, a cooling circulation mechanism is provided in the fixing shell and the core, the cooling circulation mechanism includes a cooling circulation component, a connection part and a control component, the connection part Both the control assembly and the control assembly are arranged in the middle of the cooling cycle assembly, the connection part is located between the fixed shell and the mold core, the control assembly is located in the fixed shell, and the heat insulation and cooling assembly is arranged in the mold core. The present invention can separate the incoming low-temperature coolant from the discharged high-temperature coolant through the arrangement of the heat insulation and cooling components, avoiding heat exchange between the two and reducing the cooling effect. At the same time, the structural setting of the fixing mechanism can be adjusted, extending the The service life of the equipment.

Description

technical field [0001] The invention relates to the field of mold equipment, in particular to a core-pulling cooling device for a die-casting mold. Background technique [0002] In the production process of the mold, there is inevitably a parting that is inconsistent between the product and the mold opening direction. Except for a few cases where forced demoulding can be performed, side parting and core pulling are generally required to take out the part. The device needs to be cooled during use to ensure that the alloy is not easy to stick to during the core pulling process and to ensure the roughness of the product surface. However, the die-casting cooling device in the prior art has complex structure, high cost, poor cooling effect and inconvenient use. [0003] Chinese patent number CN105665679B discloses a core-pulling cooling device for die-casting molds, which aims to solve the problems of complex structure, high cost, poor cooling effect on the core-pulling position...

However, the die-casting cooling device in the prior art has complex structure, high cost, poor cooling effect and inconvenient use

[0003] Chinese Patent No. CN105665679B discloses a core-pulling cooling device for die-casting molds, which aims to solve the problems of complex structure, high cost, poor cooling effect on the core-pulling position, and inconvenient core-pulling operation of existing die-casting cooling devices.

[0004] However, the above-mentioned patents have the following technical problems during use; first, the inner tube is located inside the outer tube, and the coolant enters the front end of the core through the inner tube and is discharged through the outer tube. However, during use, When the coolant enters the front end of the core and absorbs heat, it will exchange heat with the coolant entering from the inner tube when it absorbs heat and then discharges out through the outer tube, which will cause the temperature of the newly entered coolant to rise and reduce the cooling effect Second, in this patent, the piston cylinder and the core are fixedly connected by a quick-release transition block, wherein the position between the limiting convex ring and the connecting convex ring cannot be adjusted, and the quick-release transition block and the limiting convex ring and the connecting convex ring The clamping position between the rings cannot be adjusted, and it is easy to loosen after a long period of practical use, which will lead to the exposure of the coolant and affect the service life of the equipment
