Novel cold type die casting machine heatable feed cylinder

The utility model discloses a novel cold type die casting machine heatable feed cylinder, including material pipe and the common material cover of constituteing the return circuit of heating of material pipe that supplies the metal liquid stream to move, the beneficial effects of the utility model are that: through the high temperature oil that passes through in the material cover, feed cylinder heats preservation of can directly heating when guaranteeing the safety in production, reduces the loss of metal liquid temperature, avoid appearing since the material review the low product that results in loose, cool the line, fill discontented scheduling problem to and low grade injection molding problem is crossed to the velocity of flow, use diffusion welding (DW) welding technique, can guarantee high temperature oil and not reveal, not spill over, directly adopt current mold temperature controller, realize simply installing, need not specific temperature control device, low in manufacturing cost saves the cost f
