Abstract

PURPOSE:To improve the cooling effect of both forces to reduce molding time by placing materials with heat conductivity higher than force metal such as iron, special steel, etc. on one side of said materials and providing a cooling device such as a cooling pipe in said materials. CONSTITUTION:Materials 2 with conductivity higher than copper is provided on one side of each force 1 composed of iron, special steel, etc. and a cooling device 3 such as a cooling pipe is equipped in the materials 2 to enable the forces to be cooled. The cooling device 3 such as a cooling pipe, etc. is provided not only in the bottom force 4 but in the top force 5 of the same structure if necessary. The cooling device 3 such as a cooling pipe, etc. is provided in material 2 of copper, etc. with heat conductivity higher than the forces 1 that is incorporated in a unitary body with the forces 2 to improve cooling efficiency and to enable the forces to be cooled fully through surfaces of materials 2 high in cooling effect, and therfore it is made possible to perform uniform cooling, reduce molding time and improve productivity remarkably.

Description

Detailed Description of the Invention The present invention provides a material having a higher thermal conductivity than the material on one side of the material forming the mold, such as iron or special steel, and a cooling device such as a cooling pipe in the material. The present invention relates to a mold characterized in that it is formed by providing.

Various measures have been taken to increase the productivity of molded products such as glasstics using molds, but as a result of these various measures, it is now possible to exceed the marginal efficiency and further shorten the shot time. It is extremely difficult to shorten the shot time, and it is even said that it is extremely difficult to shorten the shot time by even one second from the current marginal efficiency.

In view of this, the purpose of the present invention is to carry out various painstaking researches,
As a result of the experiment, a material with higher P1 thermal conductivity than the material was placed on one side of the metal material that forms the mold, such as iron, special steel, etc., and a cooling device such as a cooling pipe was installed in the material to cool the mold. The object of the present invention is to provide an extremely effective and appropriate mold that can improve effectiveness, shorten molding time, and increase productivity, as well as uniform cooling and energy savings.

Further, to explain an example of implementation shown in the drawings, iron,
A material 2 having a higher thermal conductivity than the material forming the mediation mold 1 is provided on one surface of the mold 1 made of special steel, etc., and a cooling device 3 such as a cooling pipe is installed in the material 2. The mold is constructed such that it can be installed to cool the mold. Therefore, the cooling device 3 such as a cooling pipe is used not only for the lower mold 4 but also for the second mold as necessary.
As shown in the figure, it is also provided in the upper mold 5 having the same structure.

The reference numeral 6 in the figure is a mold of the desired product, and the reference numeral 7 is a mold mounting plate for an injection molding machine or the like.

As described above, the present invention provides a cooling device 3 such as a cooling pipe in the 2 surfaces of a material such as copper which has a higher thermal conductivity than the mold 1 which is bonded to the mold and formed as a barrier. In addition to increasing the cooling effect, the mold can be cooled over the entire surface through 2 meters of material with high cooling effect, which allows for uniform cooling, shortens molding time, significantly increases productivity, and saves energy. The effects are great.
