Mould for producing grey cast iron

Abstract

The invention belongs to the technical field of cast iron molds, and particularly relates to a grey cast iron production mold which comprises a lower mold body and an upper mold body, a mounting base is fixedly mounted at the bottom of the lower mold body, a groove is formed in the bottom of the mounting base, and the two sides of the groove are each in threaded connection with two first screw rods; fixing plates are fixedly connected to the ends, close to each other, of the four first screws, a rotating disc is fixedly connected to the ends, away from each other, of the four first screws, a lower mold groove is formed in the top of the lower mold, a sliding plate is slidably connected to the bottom of the lower mold groove, and a plurality of evenly-distributed spring chambers are formed in the bottom of the sliding plate; and connecting rods are slidably connected into the multiple spring chambers correspondingly, the surfaces of the connecting rods are sleeved with first springs correspondingly, a sliding cavity is formed in the bottom end of the lower mold, and a sliding block is slidably connected into the sliding cavity. The mold is convenient to mount and dismount, the mold can be accurately and rapidly closed, and meanwhile iron in the mold can be conveniently taken out.

Description

technical field [0001] The invention relates to the technical field of cast iron molds, in particular to a gray cast iron production mold. Background technique [0002] Gray iron (gray iron) is the cast iron obtained by the graphitization process in the first stage. All or most of the carbon exists in the form of flake graphite, and the fracture is gray and dark, hence the name. It includes general gray cast iron (referred to as gray cast iron), nodular cast iron, hemp cast iron, inoculated cast iron, rare earth gray cast iron, etc. The appearance of the fracture of gray cast iron is light gray, so it is called gray cast iron (gray iron). It is cheap and widely used. Gray cast iron accounts for more than 80% of the total output of cast iron. [0003] However, in the prior art, the inaccurate positioning between the upper and lower cast iron molds leads to deviations in mold clamping, which makes the cast iron effect poor. At the same time, the iron in the mold is not easy ...

Problems solved by technology

[0003] However, in the prior art, the inaccurate positioning between the upper and lower cast iron molds leads to deviations in mold clamping, which makes the cast iron effect poor. At the same time, the iron in the mold is not easy to take out after cooling, and some molten iron will remain in the casting pipe, causing waste and subsequent cooling. It is not easy to clean and cause blockage. Therefore, a gray cast iron production mold is proposed
