Drawings
Fig. 1 is a schematic cross-sectional structure of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
Wherein: 1. the die comprises a die body 2, a forming inner cavity 11, a rear side 12, a front side 13, a pipeline 14, an electric heating wire 3, a dividing knife 31, a knife edge 32, an expanded bell mouth structure 33, a notch structure 34, a knife holder 4, a shell 5 and a heat insulation material layer.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 21, a gradually cooling profile forming die comprises a die body 1, wherein the die body is provided with a forming inner cavity 2, the die body is provided with a rear side 11 (right side) for a forming material to enter, and a front side 12 (left side) for the forming material to come out from the forming inner cavity, the forming inner cavity is a cavity which penetrates from the rear side to the front side, a coiled pipeline 13 is arranged on the periphery of the die body, and a heating wire 14 is arranged in the pipeline; the method is characterized in that: the temperature of the back side of the die body after being electrified is higher than that of the front side of the die body.
Example 1
The temperature of the back side of the die body after being electrified is higher than that of the front side of the die body. Can be realized by the electric heating wire power that sets up in the mould body rear side is big, and the electric heating wire power that sets up in the mould body front side is little.
Example 2
The temperature of the back side of the die body after being electrified is higher than that of the front side of the die body. The electric heating wire density arranged on the rear side of the die body is high, and the electric heating wire density arranged on the front side of the die body is low.
Example 3
The temperature of the back side of the die body after being electrified is higher than that of the front side of the die body. Can be through setting up a plurality of heating wires around the mould body to the heating wire electric current that sets up in mould body rear side is big, and the heating wire electric current that sets up in mould body front side is little to be realized.
The invention can ensure that the temperature of the rear side and the temperature of the front side of the die body are high, so that the molding material has higher temperature in the initial molding stage and low temperature in the later molding stage, the deformation of a product (section bar) is reduced, the product quality is improved, and the purpose of the invention is realized.
Furthermore, a backward parting blade 3 is arranged at the rear side of the die body, the parting blade is provided with a blade 31 at the right end, and the parting blade is arranged around the periphery of the forming cavity.
By the arrangement, the cutting edge is beneficial to cutting the forming raw material entering the forming cavity, and the production speed is increased.
Further, the inner side of the dividing knife is formed with a rightward expanding bell mouth structure 32.
So that the speed of the raw material entering the forming cavity is faster.
Further, the blade part is provided with a triangular notch structure 33, and the notch structure is arranged backwards.
Therefore, the cutting effect on the formed raw materials is better, and the entering speed can be improved.
Furthermore, a cutter seat 34 is arranged below the dividing cutter, a cutter seat groove for installing the cutter seat is arranged on the mould body, and the cutter seat of the dividing cutter is arranged in the cutter seat groove.
By the arrangement, the dividing cutter can be replaced when damaged, and the use cost is reduced.
Furthermore, the periphery of the die body is provided with a shell 4 wrapping the die body, and a layer of heat-insulating material layer 5 is arranged between the die body and the shell.
The heat preservation effect of this mould body is better like this.
In the description of the present invention, it is to be understood that the terms "front", "rear", "left", "right", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
