no. 1 approach

[0017] Such as figure 1 The mold temperature heat conduction plastic mold shown includes a mold base 1, a male mold core 2, and a female mold core 3; In the male mold core 2, the distance from the forming surface of the male mold core 2 is 1-5mm, and the other end of the heat conduction element 4 protrudes from the male mold core 2, and the heat conduction element 4 is a copper tubular heat conduction element. The heat conduction speed of the heat pipe is fast; a heating device 5 is provided at the protruding end of the heat conduction element 4 .

[0018] With this structure, since the copper heat pipe is set in the male mold core, and the distance from the forming surface of the male mold core is 1-5mm, the heat transfer speed of the copper heat pipe is fast, so that the male mold core can be better controlled. The temperature of the mold core changes, the heating efficiency is high, and the mold is safe during work.

no. 2 approach

[0020] Such as figure 2 The mold temperature heat conduction plastic mold shown includes a mold base 1, a male mold core 2, and a female mold core 3; In the female mold core 3, the distance from the molding surface of the female mold core 3 is 1-8mm, and the other end of the heat conduction element 4 protrudes from the master mold core 3. The heat conduction element 4 is a heat conduction rod, and the heat conduction of the heat conduction rod is The speed is fast; a heating device 5 is provided at the protruding end of the heat conducting element 4 .

[0021] With this structure, since the heat conduction rod is set in the core of the master mold, and the distance from the forming surface of the core of the master mold is 1-8mm, the heat transfer speed of the heat conduction rod is fast, so that the temperature of the core of the master mold can be better controlled Changes, high heating efficiency, and the mold is safe during work.

no. 3 approach

[0023] Such as image 3 The mold temperature and heat conduction plastic mold shown includes a mold base 1, a male mold core 2, and a female mold core 3; a heat-conducting member 4 made of a heat-conducting solid is installed in the male mold core 2 and the female mold core 3, and the heat-conducting One end of part 4 is installed in the male mold core 2 and the female mold core 3, the distance between the heat conducting part 4 and the forming surface of the male die core 2 is 1-5mm, and the distance from the forming surface of the female die core 3 is 1-8mm, and the heat conducting part The other end of 4 protrudes from the male mold core 2 and the female mold core 3, and the heat-conducting member 4 is heat-conducting plastic, which has a fast heat-conducting speed;

[0024] With this structure, since the heat-conducting plastic is set in the female mold core, and the distance from the forming surface of the male mold core is 1-5mm, and the distance from the forming surface...

Abstract

The present invention discloses a mold heat transmission plastic mold which comprises a mold base and a mold kernel. The mold heat transmission plastic mold is provided with a heat conductor which is prepared by heat conducting solid. One end of heat conductor is installed in the mold kernel, and the other end extends out of the mold kernel. The mold heat transmission plastic mold of the invention can quickly increase the temperature of mold excellently and has the advantages of quick heat transmission speed and safe use.

Description

technical field [0001] The invention relates to a plastic mold, in particular to a plastic mold equipped with a mold temperature heat conduction device. Background technique [0002] Now, due to the wide use of plastic products, the plastic molds used to shape them are used more and more widely. When molding products, the heating system in the plastic mold is an important system for the quality of the product, and many technicians are also Continuous research on how to improve and control the temperature of the molded product, so that the product can meet the quality requirements for use. The current plastic molds that require high product quality are all equipped with a heating system. Generally, the medium used is water, oil or an electric heating rod. Water or oil is used as the medium, and the heating speed is slow and it is difficult to reach above 125 degrees Celsius. , using electric heating rods to heat the mold, the cost is high, and it is not safe because it needs...
