The invention discloses a belt wheel casting mould. The belt wheel casting mould comprises a casting mould tank body and a casting mould upper cover used for buckling the upper end of the casting mould tank body; a cylindrical groove is formed in the casting mould tank body; the cylindrical groove consists of an upper mould and a lower mould, namely the cylindrical groove is formed by arrangement of central cylindrical holes of the upper mould and the lower mould; an annular groove with an arc-shaped cross section is formed in the inner wall of the cylindrical groove; a supporting seat is arranged at the part, positioned below the annular groove, in the cylindrical groove of the casting mould tank body; a cylindrical projection is arranged at the center of the supporting seat; the upper mould and the lower mould are permanent magnets which are adsorbed with each other; the annular groove is embedded into a steel ring with a circular cross section; and according to the belt wheel casting mould disclosed by the invention adopting the technical scheme, firstly, the casting mould upper cover is opened, then the upper mould is taken out, the steel ring is selected at the time, then the selected steel ring is embedded into the annular groove in the lower half part of the lower mould, the permanent magnets adsorb the selected steel ring at the time, then the upper mould is assembled, finally, plastic in a molten state is injected, and then the upper cover is closed to complete the casting process.
Description
technical field [0001] The invention relates to a casting mold, in particular to a casting mold with plastic pulleys. Background technique [0002] At present, plastic pulleys are processed through plastic cylindrical discs and then ground according to requirements. Plastic debris is seriously polluted and plastic materials are wasted. It is very necessary to develop a casting method to process plastic pulleys. Contents of the invention [0003] The present invention aims at the above-mentioned technical problem, proposes a kind of casting mold of plastic pulley. [0004] In order to achieve the above purpose, it is realized through the following technical solutions: [0005] Casting mold with wheels, comprising, a casting mold box and a casting mold upper cover for buckling the upper end of the casting mold box; [0006] There is a cylindrical groove in the casting mold box; the cylindrical groove is composed of an upper mold and a lower mold, that is, the central cylin...
