Description

Technical Field

[0001] The utility model particularly relates to a hot extrusion die for producing unit curtain wall profiles. Background Art

[0002] The unitized curtain wall is an important component of the unitized curtain wall system. It involves multiple aspects such as waterproofing, drainage, and air tightness of the curtain wall. It uses the isobaric principle to form two inner and outer cavities through the insertion of the main and cross beams of the curtain wall. In the absence of a pressure difference, rainwater will not enter the inner cavity, thereby improving the waterproof performance of the curtain wall system.

[0003] The unit curtain wall is an aluminum profile produced by passing aluminum through a hot extrusion die. It has cantilevers and a tubular cavity, which is generally located at the end of the cavity. During production, the traditional hot extrusion die cannot effectively distribute the aluminum flow inside the mold body according to the characteristics of the unit curtain wall profile. As a result, the aluminum flow in the tubular cavity of the unit curtain wall has a slow flow rate, which is different from the flow rate in the rest of the unit curtain wall. The flow rate cannot be balanced, and the final quality of the profile is poor, affecting its use.

[0004] Therefore, it is necessary to invent a hot extrusion die for producing unit curtain wall profiles to solve the above problems. Utility Model Content

[0010] The die comprises a welding chamber opened on one side of the die, and a cavity connected to the welding chamber for inserting a foreman, and is used for hot extrusion production of unit curtain wall profiles;

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The utility model provides the following Figure 1-7 A hot extrusion die for producing unit curtain wall profiles shown includes a die body 1, wherein the die body 1 includes a punch 2 and a die 3 located on one side of the punch 2;

[0032] The punch 2 includes a hole 21 formed on one side of the punch 2, a diverter bridge 22 disposed within the hole 21, and the diverter bridge 22 is composed of a central body 221 located in the center of the punch 2 and in a straight line shape, and support bodies 222 distributed around the central body 221. A foreman 23 is connected to the side of the central body 221 close to the die 3.

[0033] The die 3 includes a welding chamber 31 opened on one side of the die 3 and a cavity 32 connected to the welding chamber 31 for inserting the foreman 23, which is used for hot extrusion production of unit curtain wall profiles;

[0034] Among them, the two support bodies 222 located at the rear end of the central body 221 are arranged at an angle, so that a biased hole 24 is formed between the two support bodies 222 and the inner wall of the punch 2, and a retaining wall 33 is connected to the side wall of the welding chamber 31 corresponding to the biased hole 24. The retaining wall 33 is arranged in a stepped shape, and the height gradually decreases from the outside to the inside.

[0035] In one embodiment, the hole 21 excludes the side hole 24 area, and the remaining part is separated into several diversion holes by the central body 221 and the support body 222, thereby avoiding the concentration of aluminum flow and causing uneven pressure distribution inside the punch 2. The aluminum flow is effectively guided, which can effectively reduce the impact of the aluminum flow on the punch 2 and increase the service life of the punch 2.

[0036] In one embodiment, the flow channel from the inlet to the outlet of the hole 21 is expanded to be aligned with the welding chamber 31, thereby increasing the capacity of the overall aluminum flow in the hole 21, so that the aluminum flow in the welding chamber 31 is sufficient to ensure the normal production of the unit curtain wall profile.

[0037] In one embodiment, the welding chamber 31 is provided with a baffle 34 on the inner wall at the top and bottom of the cavity 32 to restrict the flow direction of the aluminum flow so that the aluminum flow flowing out through the diversion hole can quickly enter the cavity 32, while increasing the strength of the die 3 and improving the service life of the die 3.

[0038] In one embodiment, a discharge hole 35 is further provided on the side of the die 3 away from the punch 2. The discharge hole 35 is communicated with the cavity 32 and is used for discharging the unit curtain wall profile without affecting the outer surface of the unit curtain wall profile, thereby ensuring the production quality of the unit curtain wall profile. The punch 2 and the die 3 are fastened to each other through fasteners to form a mold body 1. Specifically, the fasteners are configured as pins or bolts to facilitate the assembly of the mold body 1 by the staff, and the mold body 1 is disc-shaped as a whole, which is convenient for the staff to use the mold body 1.

[0039] The specific implementation method is as follows: When the utility model is used, Figure 6-7 As shown, the unit curtain wall profile has a section of the tube cavity located on the left side of the cavity 32, aligned with the outlet of the biased hole 24. Since it is located on the left side of the entire hole 21, it cannot be directly offset by the diversion hole. Therefore, a retaining wall 33 is added to the side wall of the welding chamber 31 at this location. Specifically:

[0040] When the aluminum flows through the hole 21 and flows into the interior of the punch 2, it will first be divided into multiple streams by the diversion hole, which avoids the uneven pressure distribution inside the punch 2 caused by the concentration of the aluminum flow, can effectively reduce the impact of the aluminum flow on the punch 2, and improve the service life of the punch 2. A part of the aluminum flows through the diversion hole to the welding chamber 31 and supplies the material to the cavity 32. At this time, the baffle 34 located outside the cavity 32 can restrict the flow direction of the aluminum flow, so that the aluminum flow flowing out of the diversion hole can quickly enter the cavity 32, avoiding the aluminum flow from being retained in the welding chamber 31, and avoiding the aluminum flow from affecting the welding and forming of the unit curtain wall profile due to uneven distribution inside the welding chamber 31. In addition, the setting of the baffle 34 can also increase the strength of the die 3, avoid the cavity 32 from being collapsed due to long-term impact, and improve the service life of the die 3.

[0041] Furthermore, a portion of the aluminum flow in the hole 21 will be divided into the inside of the biased hole 24, which is obliquely surrounded by the inner wall of the punch 2 and the two support bodies 222. The cross-sectional area of ​​the biased hole is larger, that is, the internal capacity is large, and more aluminum flow can be stored to ensure a continuous supply of material to the tube cavity part. Specifically, after entering the biased hole 24, the aluminum flow can flow toward the left side of the cavity 32, and when the aluminum flow reaches the corresponding area inside the welding chamber 31, it will be directly introduced into the left side of the cavity 32 under the limitation of the retaining wall 33, that is, at the part of the die 3 where the unit curtain wall profile tube cavity is formed, a retaining wall 33 is artificially added to guide the aluminum flow so that the aluminum flow can be quickly introduced into the cavity 32, thereby avoiding the aluminum flow from being retained here and improving the flow rate of the aluminum flow in the tube cavity, avoiding the flow rate difference between the aluminum flow here and the rest of the flow, and effectively balancing the flow rate, thereby keeping the flow rate of the aluminum flow stable as a whole, so that the final product quality of the unit curtain wall profile is guaranteed;

[0042] This embodiment specifically solves the problem that during production of the existing hot extrusion die, the distribution of the aluminum flow inside the die body 1 cannot be effectively distributed according to the characteristics of the unit curtain wall profile, resulting in a slow flow rate of the aluminum flow in the tube cavity part of the unit curtain wall, a flow rate difference with the rest of the part, and the flow rate cannot be balanced, resulting in poor quality of the final product of the profile, which affects its use.

[0043] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
