Description

Technical Field

[0001] The utility model belongs to the technical field of extrusion dies, and in particular relates to a die with a widened and raised bridge position to reduce die core deflection. Background Art

[0002] In the construction industry, curtain wall system refers to a structural system of the building's exterior facade, usually composed of panels (such as glass, aluminum panels, stone, etc.) and a supporting structure system (supporting devices and supporting structures). It has a specific load-bearing capacity, deformation capacity and the ability to adapt to the displacement of the main structure. It is also a building exterior enclosure system that integrates protection, beauty, comfort and functionality, and plays an important role in improving the overall performance and quality of the building.

[0003] Curtain wall decorative covers play an important role in curtain wall systems, beautifying the appearance of buildings, improving functionality, enhancing structural stability, and construction and maintenance. With the continuous development and innovation of building technology, the design and application of curtain wall decorative covers will continue to innovate, bringing more possibilities and value to buildings.

[0004] In the prior art, curtain wall decorative covers are usually made of aluminum profiles and are extruded by extrusion dies, such as Figure 2 The figure shows a cross-sectional view of an aluminum profile commonly used for curtain wall decorative covers. First, the mold is designed. According to the end face design of the curtain wall decorative cover, the corresponding mold is manufactured, and then the heated round aluminum rod is placed in the die base of the extruder. The strong pressure of the extruder is used to extrude the aluminum from the mold to form an aluminum profile with a specific shape and size. The extruded aluminum profile may not meet the straightness standard and needs to be sent to the straightening table for straightening.

[0005] Therefore, the extrusion die plays a vital role in determining whether the product quality of the curtain wall decorative cover is qualified. The rib position 100 of the curtain wall decorative cover is usually formed and extruded by two independent cores of the die in cooperation with the lower die. During the extrusion process, the core will receive the extrusion force and the core will deflect due to insufficient strength, resulting in unqualified quality at the rib position 100 of the curtain wall decorative cover. Utility Model Content

[0006] The main technical problem to be solved by the utility model is to provide a mold with a simple overall structure, which can solve the problem of unqualified production quality caused by core deviation by improving the strength of the core of the extrusion mold in the extrusion production of curtain wall decorative covers, while increasing the service life of the mold and improving the use effect of the mold by widening and raising the bridge position to reduce the core deviation.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0032] like Figure 1-6 As shown: a mold with a widened and raised bridge position to reduce the core deflection, including an upper mold 1 and a lower mold 4 that can be detachably installed together, a feed port group is arranged on one end surface of the upper mold 1, a core assembly 2 is arranged on the other end surface of the upper mold 1, a welding chamber 41 is opened on one end surface of the lower mold 4 close to the core assembly 2, and a lower model cavity 42 is opened at the middle position of the welding chamber 41; the core assembly 2 includes a first core 21 arranged on the other end surface of the upper mold 1, two second cores 22 are arranged at intervals and symmetrically at a position close to the first core 21 on the other end surface of the upper mold 1, and a reinforcing bridge 3 is arranged between the two second cores 22.

[0033] like Figure 4 As shown, the feed port group includes a third feed port 13 opened on an end surface of the upper mold 1 near the edge.

[0034] A third drainage groove 130 is formed on the inner wall of the hole of the third feed port 13 close to the core assembly 2 .

[0035] The first feed inlet 11 is symmetrically arranged on one end surface of the upper mold 1 with the third feed inlet 13 as the center.

[0036] A fifth feed port 15 is provided at a middle position on one end surface of the upper mold 1 .

[0037] A fourth feed inlet 14 is provided on one end surface of the upper mold 1 near the fifth feed inlet 15 .

[0038] The second feed inlet 12 is symmetrically arranged on one end surface of the upper mold 1 with the fifth feed inlet 15 and the fourth feed inlet 14 as the center.

[0039] The first feed port 11 , the second feed port 12 , the third feed port 13 , the fourth feed port 14 and the fifth feed port 15 all pass through the upper mold 1 .

[0040] The first feed port 11, the second feed port 12, the third feed port 13, the fourth feed port 14 and the fifth feed port 15 are all provided with an inverted bridge 23 at the position of the die head close to the core assembly 2, and the function of the inverted bridge 23 is to ensure feeding.

[0041] The heated round aluminum rod enters the upper mold 1 from the first feed port 11 , the second feed port 12 , the third feed port 13 , the fourth feed port 14 and the fifth feed port 15 .

[0042] A step 16 is provided on the inner wall of the fifth feed opening 15 .

[0043] The function of the step 16 is that when the heated round aluminum rod enters the fifth feed port 15, it has a relatively large impact on the core assembly 2. Here, the step 16 can prevent the core assembly 2 from receiving a large impact force, play a certain pressure relief role, and at the same time can increase the feed amount to ensure the feed.

[0044] A first drainage groove 150 is formed at a middle position of the step 16 near the core assembly 2 , and second drainage grooves 151 are formed at both sides of the step 16 near the core assembly 2 .

[0045] like Figure 3 As shown, a first gap 26 and a second gap 27 are respectively provided between the first mold core 21 and the two second mold cores 22 .

[0046] The first gap 26 and the second gap 27 correspond to the rib position 100 .

[0047] Screw hole working bands 24 are respectively arranged near the edge positions on both sides of the die head of the first mold core 21, wherein the position of one screw hole working band 24 corresponds to the position of the first drainage groove 150, and the position of the other screw hole working band 24 corresponds to the position of the third drainage groove 130.

[0048] The position of the screw hole working zone 24 also matches the screw hole 200 on the curtain wall decoration cover.

[0049] In this design, the first drainage groove 150, the second drainage groove 151 and the third drainage groove 130 are used to ensure that the screw hole working belt 24 is adequately supplied with materials, thereby ensuring that the screw holes 200 on the curtain wall decorative cover are formed to be qualified.

[0050] A rib working zone 25 is provided at a position of the first mold core 21 corresponding to the second mold core 22 , and a peripheral working zone 28 is provided at a position of the first mold core 21 and the second mold core 22 close to the rib working zone 25 .

[0051] The rib working zone 25 and the screw hole working zone 24 are shorter than the peripheral working zone 28 , so as to facilitate the feeding of the first gap 26 and the second gap 27 , thereby ensuring the forming of the rib position 100 .

[0052] like Figure 5As shown, the bridge surface of the reinforcing bridge 3 is higher than the table surface of the upper mold 1 close to the core assembly 2.

[0053] With such a design, the reinforcing bridge 3 serves to connect the two second mold cores 22, thereby reinforcing the strength of the two second mold cores 22 and avoiding the deflection of the two second mold cores 22 during the extrusion process, which would result in a decrease in the production quality of the curtain wall decorative cover. At the same time, an inverted bridge 23 structure is also provided at a position of the reinforcing bridge 3 close to the die head of the second mold core 22, further ensuring that the material is fed into the screw hole working zone 24, the first gap 26 and the second gap 27. In addition, the first drainage groove 150, the second drainage groove 151 and the third drainage groove 130 ensure the forming of the screw hole 200 and the rib position 100. At the same time, the two second mold cores 22 do not deflect, thereby improving their service life.

[0054] like Figure 6 As shown, a welding chamber 41 is provided at a position of the lower mold 4 close to the end surface of the core assembly 2 and corresponding to the core assembly 2 .

[0055] A lower mold cavity 42 is opened at a position in the welding chamber 41 corresponding to the mold core assembly 2 , and the lower mold cavity 42 penetrates the lower mold 4 .

[0056] In this embodiment, the upper die 1 and the lower die 4 are positioned and detachably connected by means of bolts and positioning pins in a common manner, which will not be described in detail here.

[0057] When in use, the heated round aluminum rod enters the upper mold 1 from the feed port group, wherein, under the action of the reinforcing bridge 3, the inverted bridge 23, the first drainage groove 150, the second drainage groove 151, the third drainage groove 130 and the rib working belt 25, it is ensured that the material can enter the first gap 26 and the second gap 27 for forming the rib position 100 and the screw hole 200. At the same time, the reinforcing bridge 3 can enhance the strength of the second mold core 22 and improve its service life. The heated round aluminum rod then enters the welding chamber 41 for welding, and then outputs a qualified curtain wall decorative cover from the lower model cavity 42.

[0058] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and deformations made to the implementation methods are still within the protection scope of the present invention.
