Description

Technical Field

[0001] The present invention relates to the technical field of casting processing, and specifically to a device for rapid cooling and demoulding of sand-castings. Sand Background Art

[0002] When producing castings, it is necessary to cool and demould them quickly. Therefore, a device for rapid cooling and demoulding of sand-castings is required. Sand casting refers to a casting method in which castings are produced in sand molds. Castings of steel, iron, and most non-ferrous alloys can be obtained by sand casting. Since the molding materials used in sand casting are inexpensive and easily available, and the manufacture of the mold is simple, it can adapt to single-piece production, batch production, and mass production of castings. For a long time, it has been the basic process in casting production. Sand mold casting is a widely used casting form. As the name suggests, it is to make a casting mold with sand. Sand mold casting requires putting a finished part model or a wooden model in the sand, and then filling the sand around the pattern. After opening the box and taking out the pattern, the sand forms the casting mold.

[0003] Currently, during the processing of castings, manual heat dissipation and demoulding are required. At present, the traditional method still uses manual heat dissipation and demoulding. The manual operation method will take more time, and when the user cools and demoulds the sand-castings, auxiliary tools are needed, which will increase the use cost. Moreover, when the user needs to place the castings before and after processing, it is not convenient enough, resulting in damage to the castings. In view of this, we propose a device for rapid cooling and demoulding of sand-castings. Summary of the Invention

In this way, the user can quickly cool the placed casting. Through the set sand removal mechanism 7, the sand can be quickly removed. When the sand on the casting needs to be quickly removed, the user needs to start the second telescopic rod 702. After the second telescopic rod 702 starts, it can push down the upper connecting frame 706. Then the output motor 708 needs to be turned on.
