Problems solved by technology

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 in 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 stress 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

Abstract

The invention discloses a lower mold moving device. The lower mold moving device comprises a lower device body, wherein mold side plates are arranged on the lower device body; two lower mold plates are arranged at the bottoms of the mold side plates; a lower mold ejection plate is arranged between the two lower mold plates; telescopic loop bars are arranged at the bottoms of the lower mold plates,and a reset spring is arranged on one side of each telescopic loop bar; a drive rod is arranged at the bottom of the lower mold ejection plate; a first connecting shaft I is arranged on the side wallof the bottom end of the drive rod; a first connecting shaft II is arranged on the outer wall of the first connecting shaft I in a sleeving manner; a transmission shaft is arranged on an outer ring of the first connecting shaft II; a transmission connecting slot is formed in the middle of the lower device body. According to the lower mold moving device, a drive motor is utilized to drive a rotating disc to work, the drive rod drives the lower mold ejection plate to move downwards, the reset springs enable the lower mold plates to reset, so that the lower mold plates and the mold side plates are separated from the lower mold ejection plate, and a formed mold falls off and is convenient to take out.

Description

technical field [0001] The invention relates to the field of mold casting, in particular to a lower mold moving 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 world, 60-70% of all castings are produced by sand casting. Compared with other casting methods, sand casting has low cost, simple production process and short production cycle. 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 in the mold. Sand mold, the method of taking out the sand mold is mainly manual,...
