Description

Extrusion die for trapezoidal hollow solar panels

technical field

The invention relates to a plate extrusion molding equipment, in particular to an extrusion die head of a trapezoidal hollow sunlight plate.

Background technique

Due to the limitation of processing molds, the trapezoidal sun panels commonly used in the existing market are all solid structures, not only the consumables are large, the cost is high, and the specific gravity is large, the most important thing is that the performance of the panels is insufficient, with poor light transmission, average strength, and sound insulation. The defect of poor effect.

Contents of the invention

In view of the above defects, the object of the present invention is to provide a trapezoidal hollow solar panel extrusion die head, the solar panel produced by it is a trapezoidal hollow corrugated panel, which has the advantages of less consumables, low cost, light weight, easy installation, and sealing Strong performance, high product strength and good light transmission.

To achieve the above object, the present invention adopts the following technical solutions:

An extrusion die head for a trapezoidal hollow solar panel, characterized in that it mainly includes a die body, an upper die lip, a lower die lip and a die core, the die body is provided with two fluid inlets; The upper die lip is arranged on the front side, and the upper die lip insert is arranged on the front lower side of the upper die lip, and the upper die lip and the upper die lip insert are combined to form a first flow channel, the first flow channel is connected with the fluid inlet above the mold body; the lower die lip is arranged on the lower side of the front of the die body, and the lower die lip insert is arranged above the front side of the lower die lip, and the lower die lip insert Combined with the lower die lip to form a second channel with the core, the second channel is connected to the fluid inlet below the mold body; the front end of the core is a trapezoidal wave structure, and the upper The corresponding surfaces of the die lip insert, the lower die lip insert and the mold core are also arranged in a trapezoidal wave structure; a plurality of straight guide grooves connecting the first runner and the second runner are arranged on the top of the mold core, and High-pressure air outlets are arranged on the end faces between adjacent straight guide grooves.

Further, a large gap is provided on both sides of the corrugated structure of the mold core so that the first runner and the second runner are combined into one at the gap.

Further, the bottom of the above-mentioned straight guide groove is a slope structure with the upper part higher than the lower part.

During processing, the materials enter the two fluid inlets of the mold body respectively, and then flow through the first flow channel and the second flow channel respectively and come out from the outlet to form the upper and lower structure of the trapezoidal wave plate. Here, when the material flows through the mold At the top surface of the core, due to the existence of straight guide grooves, the materials in the first flow channel and the second flow channel will enter until the grooves form the connecting ribs connecting the upper and lower layers of the plate, and because of the air outlet between adjacent straight guide grooves The ejection of high-pressure gas forms a hollow cavity structure between adjacent connecting ribs.

The solar panel produced by the above die head is a trapezoidal hollow corrugated panel, which has the advantages of less consumables, low cost, light weight, high product strength and good light transmission.

In addition, because the first flow channel and the second flow channel are combined into one at the large gaps on both sides of the wave structure of the mold core, this structure can form a solid buckle on both sides of the processed plate, which facilitates the connection between the plates. Quick installation and connection can effectively improve the installation strength and connection sealing of the solar panels.

Detailed ways

As shown in Figure 1-4, an extrusion die head of a trapezoidal hollow solar panel mainly includes a die body 1, an upper die lip 2, a lower die lip 3 and a die core 4.

The mold body 1 is provided with two fluid inlets 11, 12, and the structural design of the double flow channel is conducive to providing sufficient fluid, so as to realize the stability of production and ensure the production of high-quality products.

The upper front side of the mold body 1 shown above is provided with the upper die lip 2, and the lower front side of the upper die lip 2 is provided with an upper die lip insert 5, and the upper die lip 2 and the upper die lip insert 5 are combined to form a A first flow channel 71 is formed between the mold cores 4 in the front middle of the body 1 , and the first flow channel 71 communicates with the fluid inlet 11 above the mold body 1 .

The lower die lip 3 is arranged on the front lower side of the mold body 1, and the lower die lip insert 6 is arranged on the upper front side of the lower die lip 3. A second flow channel 72 is formed between them, and the second flow channel 72 communicates with the fluid inlet 12 below the mold body 1 .

The front end of the mold core 4 has a trapezoidal corrugated structure 41 , and the corresponding surfaces of the upper die lip insert 5 , the lower die lip insert 6 and the die core 4 are also provided with trapezoidal corrugated structures 51 and 61 respectively.

A plurality of straight guide grooves 42 communicating with the first runner 71 and the second runner 72 are arranged on the top of the mold core 4 , and high-pressure air outlet holes 43 are arranged on the end surface between adjacent straight guide grooves 42 . Here, considering factors such as the extrusion pressure and flow direction of the material, the bottom of the above straight guide groove 42 is set as a slope structure with the upper part higher than the lower part, so as to ensure that the materials in the first flow channel 71 and the second flow channel 72 are in the outlet. The feed ports can smoothly meet and connect.

During processing, the materials enter from the two fluid inlets 11 and 12 of the mold body 1 respectively, and then flow through the first flow channel 71 and the second flow channel 72 respectively and come out from the outlet to form the upper and lower layers 91 and 92 of the trapezoidal wave plate. , and its structure is shown in Figure 5. Here, when the material flows through the top surface of the mold core 4, due to the existence of the straight guide groove 42, the material in the first runner 71 and the second runner 72 will enter until the groove 42 forms the upper and lower layers 91, 92 of the connecting plate. The connecting ribs 93, and due to the ejection of high-pressure gas in the air outlet holes 43 between adjacent straight guide grooves 42, a hollow cavity 94 structure is formed between adjacent connecting ribs 93.

The solar panel produced by the above die head is a trapezoidal hollow corrugated panel. Its structure is shown in Figure 5. It has the advantages of less consumables, low cost, light weight and good light transmission.

Here, a large notch 42 is provided on both sides of the wave structure 41 of the mold core so that the first runner 71 and the second runner 72 are combined into one at the notch. This structure can make both sides of the processed plate form a solid The thin buckle 95 is very convenient for quick installation and connection between panels, and can effectively improve the installation strength and connection sealing of the sun panels.

The above is only a preferred embodiment of the present invention, and is not intended to limit the invention in any form. Any simple modifications, equivalent changes or modifications made to the above embodiments according to the technical principles of the present invention still belong to this invention. within the scope of the technical solution of the invention.
