Die set

Technical Field

The invention relates to the technical field of machining, in particular to a die.

Background

In the processing of thermoplastic resin products, a mold is a key processing device, and since thermoplastic resin materials are lightweight, a common processing method is an injection molding method in which a mold is filled with a thermoplastic resin in a molten state and then cooled to finally obtain a desired shape, and a pattern, a shape, and the like are formed inside the mold.

People often choose improved materials in order to improve the quality of products. However, since the improved material generally requires a high temperature to melt, if the mold temperature is increased, the time required for cooling and solidifying the plasticized thermoplastic resin is increased, and therefore, there has been an attempt to reduce heat loss by providing a heat insulating layer inside the mold, but the heat insulating layer is sometimes partially broken due to instantaneous heat and heat exchange when the contact positions of the two molds are reopened.

Disclosure of Invention

The invention aims to provide an energy mold, and the energy mold solves the problems.

The technical scheme of the invention is as follows: the utility model provides a mould, includes mould and lower mould, the inner wall of going up the mould and the inner wall of lower mould are the bottom surface promptly and all are provided with the insulating layer, insulating layer one end on the inner wall is connected as an organic wholely with the insulating layer on the bottom surface, and the other end extends to and is close to the hookup location of mould and lower mould.

Preferably, the heat insulation layer is horizontally arranged close to the connecting position of the upper die and the lower die, the width of the heat insulation layer is 0.2-0.3mm, and the distance between the heat insulation layer and the inner contact surface of the upper die and the lower die is 0.25-0.35 mm.

Preferably, the width of the heat insulation layer is 0.2-0.3mm,

the part close to the connecting position of the upper die and the lower die is obliquely and horizontally arranged, the included angle between the part and the vertical direction is 30-45 degrees, and the distance between the part and the inner contact surface of the upper die and the lower die is 0.05-0.10 mm.

The invention provides a die, wherein a contact surface of a heat insulation layer in the die is not contacted between two split bodies, so that the problem that the heat insulation layer is broken is not easy to occur.

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

The invention provides a die, which comprises an upper die 1 and a lower die 2, wherein the inner walls of the upper die and the lower die, namely the bottom surfaces, are respectively provided with a heat insulation layer 3, one end of each heat insulation layer on the inner wall is connected with the heat insulation layer on the bottom surface into a whole, and the other end of each heat insulation layer extends to a position close to the connection position of the upper die and the lower die.

Preferably, referring to fig. 2, the heat insulation layer is horizontally arranged close to the connecting position part of the upper die and the lower die, has a width of 0.2-0.3mm and is 0.25-0.35mm away from the inner contact surface of the upper die and the lower die. The design can ensure the internal temperature of the die and is not easy to cause the problem of local crack.

Preferably, referring to fig. 3, the width of the heat insulation layer is 0.2-0.3mm, the part of the heat insulation layer close to the connecting position of the upper die and the lower die is obliquely and horizontally arranged, the included angle between the heat insulation layer and the vertical direction is 30-45 degrees, and the distance between the heat insulation layer and the inner contact surface of the upper die and the lower die is 0.05-0.10 mm. Compared with the preferred mode, the design has better heat preservation effect and is not easy to generate the problem of local crack.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
