Abstract
An improved hot nozzle heat conduction structure of a hot runner comprises a hot nozzle embedded in a mold core, wherein a heat conduction coating is arranged on a fit clearance between the hot nozzle and the mold core; the heat-conducting coating at least comprises a silicone grease groove arranged on the hot nozzle and a filler which is arranged in the silicone grease groove by coating and is used as a heat-radiating medium; the filler is at least heat dissipation silicone grease; the filler is at least heat dissipation silicone grease. The utility model discloses increase the silicone grease groove on hot mouth, smear heat dissipation silicone grease on the silicone grease groove, utilize heat dissipation silicone grease as the principle of heat-dissipating medium to reach the purpose of filling the clearance between hot mouth and the mold core, make every hot mouth's coefficient of heat conductivity balanced, improve the radiating efficiency. The problems of unbalanced glue feeding, water gap breaking, long product forming period and the like of the fan blade open type hot runner mold can be solved.
Description
Technical Field
The utility model relates to an adopt open hot runner mold's structure, specifically be a hot mouth heat conduction structure of modified hot runner.
Background
The existing mould adopting the open type hot runner has the following problems:
1) the cooling water delivery can not be directly designed near the hot nozzle, and most of heat can be taken away too close to the hot nozzle, so that the injection molding is influenced.
2) The cooling water transportation can not take away the heat in time too far, finally leads to the heat to pile up the mouth of a river fracture that appears, needs extension cooling time just can solve.
3) The mold core processing precision of the mold is not enough, the tightness of each hot nozzle is inconsistent, so that the heat dissipation effect of each hot nozzle is different, and the injection molding glue-moving balance is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can improve the hot mouth heat conduction structure of hot runner of improved that the income of open hot runner mold of fan blade class is glued unbalance, disconnected mouth of a river, product shaping cycle length scheduling problem to overcome the weak point among the prior art.
The improved hot nozzle heat conducting structure for the hot runner comprises a hot nozzle embedded in a mold core, and a heat conducting coating is arranged on a fit clearance between the hot nozzle and the mold core.
The heat-conducting coating at least comprises a silicone grease groove arranged on the hot nozzle and a filler which is arranged in the silicone grease groove by coating and is used as a heat-radiating medium.
The filler is at least heat dissipation silicone grease. The gap between the hot nozzle and the mold core is filled by utilizing the principle that the heat dissipation silicone grease is used as a heat dissipation medium, so that the heat dissipation of the hot nozzle is more efficient and stable.
The hot nozzle is provided with a silicone grease groove corresponding to the matching position of the hot nozzle and the mold core.
And matching sections are respectively arranged between the hot nozzle and the mold core so as to enable the hot nozzle and the mold core to be tightly assembled. The hot nozzle and the mold core are additionally provided with a matching section to prevent the heat dissipation silicone grease from leaking out towards the silicone grease groove.
The width of the silicone grease groove is 0.01mm to 0.03 mm.
The groove width of the silicone grease groove is preferably 0.01 mm.
The utility model has the advantages as follows:
the silicone grease groove is added on the hot nozzle, the heat dissipation silicone grease is smeared on the silicone grease groove, and the principle that the heat dissipation silicone grease is used as a heat dissipation medium is utilized to achieve the purpose of filling the gap between the hot nozzle and the mold core, so that the heat conductivity coefficient of each hot nozzle is balanced, and the heat dissipation efficiency is improved. The problems of unbalanced glue feeding, water gap breaking, long product forming period and the like of the fan blade open type hot runner mold can be solved.
