Description
Technical Field
The utility model relates to an aluminum profile mold, in particular to an aluminum profile forming mold without a welding line on the surface.
Background
The aluminum profile is obtained by extruding an aluminum alloy material on an extruder through an aluminum profile die. The existing aluminum profile die comprises an upper die and a lower die, wherein the upper die is provided with a feeding port, and the lower die is provided with a discharging port. Some aluminium alloy have higher surface quality requirement, require the side of product can not have the welding line, and traditional aluminium alloy mould, as shown in fig. 1, go up mould 10 and be equipped with six feed chute 101, go up mould 10 department and have lacing wire 102 for the side of shaping product, this makes the lateral surface of product 10 have the welding line, can not satisfy the requirement of product to the appearance quality.
Disclosure of Invention
The utility model aims to provide an aluminum profile forming die without a welding line on the surface.
In order to achieve the purpose, the technical solution of the utility model is as follows:
the utility model relates to an aluminum profile forming die without a welding line on the surface, which comprises an upper die and a lower die; the bottom surface of the upper die covers the top surface of the lower die; the upper die is provided with a feed chute and a male die head, the lower die is provided with a discharge chute, and the feed chute of the upper die is communicated with the discharge chute on the lower die; the male die head consists of two lateral male die heads and a middle male die head; the two lateral male die heads are respectively positioned at two sides of the middle male die head, the front surface and the back surface of the middle male die head are both provided with reinforcing blocks, the wall surfaces of the feeding grooves opposite to the front surface and the back surface of the middle male die head are arched inwards to form arched blocks, and the size of the feeding grooves at the positions is reduced; the upper die is provided with four feeding grooves which are arranged around a male die head on the upper die; and a blocking step is arranged at the inlet of the lower die discharge chute.
The inner wall of the arch block on the wall surface of the feeding groove is an arc surface.
After the scheme is adopted, the four feeding grooves are formed in the upper die, no tie bar is arranged at the position of the upper die corresponding to the side face of a molded product, the requirement that the side face of the product has no welding line is met, in order to avoid the deviation of the middle male die head, the front face and the back face of the middle male die head are both provided with the reinforcing blocks, the effect of increasing the strength of the middle male die head is achieved, the wall faces of the feeding grooves opposite to the front face and the back face of the middle male die head are arched inwards, the size of the feeding grooves at the position is small, and the deviation force generated by the middle male die head is reduced.
The utility model is further described with reference to the following figures and specific embodiments.
Drawings
Fig. 1 is a schematic view of a conventional aluminum profile mold;
FIG. 2 is a schematic structural view of the present invention;
FIG. 3 is an isometric view of an upper die of the present invention;
fig. 4 is an isometric view of the lower die of the present invention.
Detailed Description
As shown in fig. 2-4, the utility model relates to an aluminum profile forming die without weld lines on the surface, which comprises an upper die 1 and a lower die 2.
The bottom surface of the upper die 1 covers the top surface of the lower die 2; the die is characterized in that the upper die 1 is provided with a feed chute 11 and a male die head 12, the lower die 2 is provided with a discharge chute 21, and the feed chute 11 of the upper die 1 is communicated with the discharge chute 21 on the lower die 2.
The upper die 1 is provided with four feeding grooves 11, the four feeding grooves 11 are arranged around the male die head 12 on the upper die 1, and the male die head 12 is composed of two side male die heads 121 and a middle male die head 122; the two lateral male die heads 121 are respectively located at two sides of the middle male die head 122, the front face and the back face of the middle male die head 122 are both provided with reinforcing blocks 1221, the wall faces of the feeding chute 11 opposite to the front face and the back face of the middle male die head 122 are arched inwards to form an arched block 111, and the inner wall of the arched block 111 is an arc-shaped face, so that the size of the feeding chute 11 at the position is smaller. It should be noted that the height of the male die 12 of the present invention is lower than that of the conventional male die, so that the male die 12 of the present invention is not easy to swing.
In order to prevent the outer side surface of the thickened part of the product from forming stripes, a blocking step 22 is arranged at the inlet of the discharge chute 21 of the lower die 2, and the effect of slowing down the flow speed is achieved.
The working principle of the utility model is as follows:
1. the front and the back of the middle male die 122 are both provided with reinforcing blocks 1221, which play a role in increasing the strength of the middle male die 122;
2. the opposing wall surfaces of the feed chute 11 at the front and back of the center male die 122 are inwardly curved so that the feed chute 11 has a smaller size at that location and the biasing force generated to the center male die 122 is reduced.
The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the utility model, which is defined by the appended claims and their equivalents and modifications within the scope of the description.
