Energy-saving and environment-friendly die for metal die-casting

Abstract

The invention relates to the technical field of dies, and discloses an energy-saving and environment-friendly die for metal die-casting. The energy-saving and environment-friendly die comprises a bottom die, wherein a liquid collecting disc is fixedly mounted at the bottom of an inner cavity of the bottom die, a sealing disc is rotatably connected to the upper end of the liquid collecting disc, and positioning strips are fixedly connected to the left wall and the right wall of the inner cavity of the bottom die; and an elastic abutting rod is slidably connected to the middle of each positioning strip, a guide block is slidably connected to the outer side of each positioning strip, a connecting rod is movably connected between each guide block and the corresponding elastic abutting rod, anda guide rod extending to the upper end of the liquid collecting disc is movably connected to each guide block. According to the energy-saving and environment-friendly die for metal die-casting, transmission gears are controlled to drive magnet sheets to deflect and repel elastic bent rods to open ball valves by utilizing the thermal expansion and cold contraction characteristics of hot air bag rings in the inner cavity of the bottom die so as to release cooling liquid; and then the sealing disc is controlled to correspondingly deflect, so that a casting can be automatically cooled, and cooling liquid after used can be effectively collected and stored.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an energy-saving and environment-friendly metal die-casting mold. Background technique [0002] At present, after the mold is used to die-cast the molten metal, it is necessary to cool the corresponding casting to improve the processing efficiency of the casting. When the general metal die-casting mold is used for die-casting, it is necessary to manually control the temperature of the casting according to the degree of completion of the die-casting. Castings are fed with cooling liquid to achieve the purpose of accelerated cooling of castings and easy demoulding. However, there are many shortcomings of manual control of cooling liquid. It is troublesome to start and stop the coolant. In addition, most of the coolant will flow out from the corresponding die-casting tank to the recovery mechanism after it is passed to the casting, and the cavity of the recovery mechanism is generally...

[0002] At present, after the mold is used to die-cast the molten metal, it is necessary to cool the corresponding casting to improve the processing efficiency of the casting. When the general metal die-casting mold is used for die-casting, it needs to be manually controlled according to the degree of completion of the die-casting. The cooling liquid is passed through the castings to achieve the purpose of accelerated cooling of the castings and easy demoulding. However, there are many disadvantages of manual control of the cooling liquid. One is that the time of feeding cannot be accurately controlled. It is more troublesome to start and stop the coolant. In addition, most of the coolant will flow out from the corresponding die-casting tank to the recovery mechanism after being passed to the casting, and the cavity of the recovery mechanism is generally connected to the outside world for a long time. Effective sealing measures, so it is easy to cause the collected coolant to deteriorate and become dirty

[0003] Aiming at the deficiencies of the prior art, the present invention provides an energy-saving and environment-friendly metal die-casting mold, which has the advantages of being convenient to automatically cool the casting and effectively collecting and storing the used cooling liquid, and solves the problem of general metal die-casting. When using a mold for die-casting, it is necessary to manually control the cooling of the casting through cooling, and the used coolant cannot be effectively collected and stored.
