The reference numbers in the figures are: the method comprises the following steps of 1-casing, 2-core rod, 3-heat dissipation part, 301-heat dissipation plate, 302-concave part, 4-sealing plug and 5-high temperature heat conduction oil.

Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 1-2, a deep cavity heat conduction device of a rotational molding die comprises an outer shell 1 with a cavity, a core rod 2 arranged in the cavity, and a heat dissipation part 3 arranged at the upper part of the outer side of the outer shell, wherein a sealing plug 4 is arranged at the upper part of the cavity, so that the core rod can slide along the inner part of the cavity.

The cavity is filled with high-temperature heat conduction oil 5.

The diameter of the shell is reduced in a step mode from top to bottom.

The heat dissipation part comprises a plurality of heat dissipation fins 301 which are arranged up and down and surround the upper part of the outer side of the shell.

The heat dissipation part is provided with a concave part 302 for installation and adaptation.

The shell and the core rod are made of red copper.

Practice proves that compared with a solid deep-cavity heat conduction device, the deep-cavity heat conduction device with the core rod and the heat conduction liquid has a better heat conduction effect in production, and the reason is that the core rod continuously moves in the overturning process of the rotational molding die, so that high-temperature heat conduction oil is forced to flow, and the heat conduction efficiency is higher.

When the device is used, the rotational molding die deep cavity heat conduction device is inserted into the deep cavity part of the die, and when the die is heated (enters a drying room), the radiating fins absorb heat from the outside and transmit the heat to the deep cavity part through the heat conduction liquid, so that the heat conduction efficiency is accelerated; when the mold is cooled (taken out of the drying room), the heat conduction liquid transfers the heat of the deep cavity part to the radiating fins and quickly releases the heat to the outside to accelerate cooling.

Example 2
