Embodiment 1
[0032] Such as figure 1 As shown in -3, the outer surface of the plastic part is formed by the cavity arranged in the fixed mold. The circular end surface of the outer surface is equipped with a planar vortex-shaped cooling pipe. The two ends of the pipe are connected in series with the medium pipes. , the other end is connected with the medium inlet and outlet horizontal hole passing through the adjacent formwork, and the connection is sealed with a sealing ring to ensure no leakage. The cooling medium enters from the horizontal hole near the gate and flows out from the other end away from the gate.
[0033] The outer surface of the plastic part is equipped with a plurality of combined cooling pipes that fit the shape of the outer periphery. The axis of each pipe is located in the reference plane, and the reference plane is perpendicular to the outer peripheral side. Each pipe includes multiple large-diameter arc pipes and multiple small-diameter circles. All the pipes are c...

[0036] The inner surface of the plastic part shell is formed by the core arranged on the movable mold. The inner surface of the large-diameter cylindrical shell is equipped with a helical pipe connected to a plane vortex pipe to form a series cooling pipe. The helical pipe and the vortex pipe have the same direction of rotation. The pipe connection form adopts circular arc tangential connection. The central axis of the spiral pipe and the plane where the vortex pipe is located are in a vertical position. The vortex cooling pipe cools the circular plane part of the inner surface of the plastic part. The inner surface of the plastic part is cooled. One end of the vortex pipe is connected to the medium inlet pipe. The medium inlet pipe is perpendicular to the plane where the vortex pipe is located. The inlet pipe is perpendicular to the plane of the vortex pipe. One end of the spiral pipe is connected to the medium outflow pipe. The outlet pipe is parallel to the inlet pipe, and b...

[0039]The inner surface of the small-diameter cylindrical shell on the inner surface of the plastic part is equipped with a jet tube cooling pipe to cool the circular plane part and the circumference part of the inner surface of the plastic part. The cooling medium is sprayed from the top of the jet tube and shunts around to cool the core wall , the ratio of the inner tube diameter to the outer tube diameter of the small diameter in the jet tube is 0.707, the inner tube and the outer tube have the same flow assist, the jet tube is threaded into the core, the medium inlet and outlet are connected to the cooling medium on the adjacent formwork The inlet and outlet horizontal holes are connected, and the nozzle pipe is made of copper pipe, and the sealing ring is used to seal the connection with the medium inlet and outlet horizontal holes passing through the formwork to ensure that the connection does not leak.
