Automatic demolding device

Abstract

The invention relates to the field of molds and particularly discloses an automatic demolding device. The automatic demolding device comprises a rack, a mold body, a first separation device and a second separation device. The first separation device of the automatic demolding device is fixedly mounted at the bottom of the rack. The second separation device is fixedly mounted at the top of the rack. The first separation device comprises a threaded rod, a first connecting rod mechanism, a handle, a locating block and a gear, wherein the gear is engaged with the threaded rod. The mold body is detachably connected with the upper end of the threaded rod. The locating block is eccentrically arranged on the side face of the gear. One end of the first connecting rod mechanism is connected with the locating block, and the other end of the first connecting rod mechanism is connected with the handle. The second separation device comprises a separation motor, a transmission shaft and a second connecting rod mechanism. The separation motor is connected with one end of the second connecting rod mechanism, and the other end of the second connecting rod mechanism is connected with one end of the transmission shaft. The other end of the transmission shaft is detachably connected with the upper surface of an upper mold. By means of the automatic demolding device, a pressure-casting mold can be manufactured, and a molding mold can be separated from the mold body automatically.

Description

technical field [0001] The invention belongs to the field of mold casting, and in particular relates to a demoulding device. Background technique [0002] Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. At present, in the international production of all castings, 60-70% of the castings are produced by sand casting. Compared with other casting methods, sand casting has low cost, simple production process and short production cycle. [0003] In the manufacturing process of sand molds, each sand mold needs to be processed and shaped separately. First, the casting sand is filled into the mold, and then the casting sand in the mold is pressed to ensure that the casting sand is tightly bonded, and then the mold is taken out. Sand mold, the m...

[0003] In the manufacturing process of sand molds, each sand mold needs to be processed and formed separately. First, fill the casting sand into the mold, and then press the casting sand in the mold to ensure that the casting sand is tightly bonded, and then take out the mold. Sand mold, the method of taking out the sand mold is mainly manual, and it is easy to misuse the manual when taking out the mold, resulting in uneven force on the sand mold, which in turn leads to deformation of the sand mold, making the sand mold unable to form, wasting manpower and material resources
