The technical scheme is as follows: in order to solve the technical problem, the utility model discloses a technical scheme does:
a fast cooling injection mold comprises an upper mold, a lower mold and a cooling device;
the upper die is provided with an upper die cavity, the lower die is provided with a lower die cavity, and the upper die cavity and the lower die cavity are matched to form a forming cavity after die assembly; a pouring channel which penetrates through the forming cavity is arranged on the top surface of the upper die;
the cooling device comprises a cooling pipe and a water storage tank, a cooling cavity is arranged in the lower die and is positioned below the lower die cavity, and the shape of the cooling cavity is matched with that of the lower die cavity; the cooling pipe is arranged in the cooling cavity; the cooling cavity is filled with heat conducting materials; the water storage tank is fixed on the outer side of the lower die, a water inlet pipe is connected with a water inlet of the cooling pipe, a water outlet pipe is connected with a water outlet pipe, and the water inlet pipe and the water outlet pipe are both connected with the water storage tank.
Further, the upper wall of the cooling cavity is provided with corrugated grooves.
Further, the cooling pipe is of a serpentine structure.
Further, the heat conduction material is a heat conduction silica gel pad.
Further, the water inlet pipe is connected with the water storage tank through a micro-circulation water pump.
Furthermore, a condensation pipe is arranged outside the water outlet pipe.
Has the advantages that: the utility model provides a quick-cooling injection mold, which improves the efficiency of transferring heat in the cavity to cooling water and accelerates the cooling rate by filling the cooling cavity with heat conduction materials; the corrugated groove is formed in the upper wall of the cooling cavity, namely one side close to the forming cavity, so that the contact area of the cooling cavity and the lower die is increased, and the heat dissipation efficiency is improved; this application mould is from taking circulating water system, through outlet pipe flow direction storage water tank behind the water heat transfer in the cooling pipe to through the condenser pipe cooling before flowing into the storage water tank, become cold water inflow storage water tank again, the water in the storage water tank passes through micro-circulating water pump and during inlet tube gets into the cooling pipe, cools off the shaping die cavity, cyclic utilization water resource, energy-concerving and environment-protective.
