It is embedded in a hollow rotating heat conducting bar in PRECISION HOLE, the rotating heat conducting bar lower end is connect with cooling device, cooling dress
It sets and is bolted on bottom plate.
The cooling device includes water flowing block, and water flowing block is equipped with water inlet pipe, sparge pipe, outlet pipe, the water inlet
Pipe is connected to sparge pipe, and sparge pipe is located inside rotating heat conducting bar, and rotating heat conducting bar is mounted on water flowing block by sealing ring,
The outer wall of sparge pipe and the inner wall of rotating heat conducting bar form gap runner, and outlet pipe is then connected to gap runner.
Preferred rotating heat conducting bar is red copper bar, is filled with heat-conducting silicone grease between rotating heat conducting bar and rotation thread core.
Flexible gap is equipped between the top and rotation thread core of the rotating heat conducting bar；The lower end of rotating heat conducting bar with
Flexible gap is equipped between water flowing block.
Design of the beneficial effects of the utility model due to rotating thread core internal precision hole, passes through rotating heat conducting bar and spray
Water pipe can carry out cooling treatment to it, and then shorten the period of injection moulding production, greatly improve production efficiency, subtract
The increase of cost is lacked.And the both ends of rotating heat conducting bar are equipped with flexible gap, prevent thermal expansion from generating big interference, destroy mould
Has precision.

Specific embodiment
A kind of mold with cooling rotating core, successively includes sky plate (1), push plate (2), dynamic mould fixing plate from top to bottom
(3), the type chamber (6) formed between mould leg (4), bottom plate (5) and sky plate (1) and push plate (2).Rotate the demoulding of thread core (7)
The top at end passes through dynamic mould fixing plate (3) and push plate (2) and is located in type chamber (6), sets between the demoulding end and push plate (2)
Have ejector sleeve (8), it is internal that ejector sleeve (8) is fixed by screws in push plate (2).The rotation thread core (7) is fixed with dynamic model
Thrust bearing (9), ball bearing (10), tapered roller bearing (11), rotate gear (12) are from top to bottom once equipped between plate (3)
The round end of rotation thread core (7) is mounted on by locking nut (13), the rotate gear (12) is located at two mould legs
(4) between.Be the PRECISION HOLE of an inner wall smooth among the rotation thread core (7), PRECISION HOLE be embedded in one it is hollow
Rotating heat conducting bar (14), insertion when smears heat-conducting silicone grease on rotating heat conducting bar (14).Preferred rotating heat conducting bar
It (14) is transcalent red copper bar, rotating heat conducting bar (14) is rotated together with thread core (7) are rotated, and thawing when being injected into production
Plastics bring heat will further generate thermal expansion, and further enhance the tension force generated, with rotation thread core (7)
Closer is linked together.Described rotating heat conducting bar (14) lower end is connect with cooling device, and cooling device is solid by bolt
It is scheduled on bottom plate (5).
The cooling device includes water flowing block (15), and water flowing block (15) is equipped with water inlet pipe (16), sparge pipe (17), goes out
