Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum profile processing, and in particular relates to an aluminum profile hot extrusion die which is easy to position. Background Art

[0002] At present, industrial aluminum profiles account for about 30% of the total aluminum profile application, and are mainly used in the transportation industry (including automobile manufacturing, rail transportation industry), equipment and machinery manufacturing, durable consumer goods industry (including light industry), etc. Hot extrusion is the earliest extrusion forming technology adopted among several extrusion processes. It is a process of extruding metals at hot forging temperatures with the help of the good plasticity of the material. It is widely used in the production of tubes and profiles of non-ferrous metals such as aluminum and copper, etc., and belongs to the scope of the metallurgical industry. Aluminum profile extrusion is a plastic processing method that applies external force to the metal billet placed in the container (extrusion barrel) to make it flow out of a specific die hole to obtain the required cross-sectional shape and size. The vast majority of hot-deformed aluminum manufacturers use the forward hot-deformed extrusion method to obtain aluminum materials with the required cross-sectional shape through a specific die.

[0003] However, the existing aluminum profile hot extrusion dies are generally fixed by pins, but the pin holes in the upper and lower dies are difficult to align, which easily increases the installation time of the dies. In addition, the pins that fix the dies generally have a small taper, and the pins are prone to misalignment during installation. It is easy to install the pins upside down, resulting in large wall thickness deviation and size misalignment.

[0004] In the prior art, there is a Chinese patent that has been published, with publication number CN212760400U, which discloses a hot extrusion die for aluminum profiles that is easy to position. The scheme includes an upper die plate (1) and a lower die plate (2), wherein the lower die plate (2) is installed corresponding to the lower end of the upper die plate (1), and is characterized in that the upper surface of the lower die plate (2) is fixedly connected with positioning columns (3) all around, the bottom surface of the upper die plate (1) is fixedly connected with positioning rods (4) that are movably connected to the positioning columns (3) all around, and the two sides of the upper die plate (1) are fixedly connected with positioning devices (5). Although this scheme solves the problem of poor alignment of the pin holes of the upper and lower dies, the positioning of the upper and lower dies is relatively cumbersome, and they must be repositioned after each extrusion, which wastes working time and reduces production efficiency.

[0005] Therefore, improvements are urgently needed. Utility Model Content

[0006] In view of the above-mentioned defects in the prior art, the utility model provides an aluminum profile hot extrusion mold that is easy to position, including a lower template, a column, a vertical plate and an upper template.

The column is fixed on the top surface of the lower template and is located at the rear end of the left side of the lower template. Vertical limiting grooves are arranged on the front and rear sides of the column. The vertical plate is located above the lower template, and the bottom end of the vertical plate is fixed on the rear side wall of the right end of the lower template. A vertical guide groove is arranged on the vertical plate. The upper template is correspondingly arranged above the lower template, and an insert block matching the slot is arranged at the bottom of the upper template. A through hole for the column to pass through is opened at the rear end of the left side of the upper template, and the through hole is adapted to the shape of the column. Bosses adapted to the two vertical limiting grooves are respectively arranged on the front and rear sides of the through hole, and the positions of the two bosses are at the same height. A convex block is arranged on the rear side wall of the right end of the upper template, and the convex block is adapted to the guide groove of the vertical plate.

[0007] Optionally, an annular limiting groove adapted to the convex column of the upper template is provided on the upper part of the column, and the annular limiting groove and the vertical limiting groove are interconnected.

[0009] Optionally, the top of the vertical limiting groove is at the same height as the top of the column, and the top of the guide groove is at the same height as the top of the vertical plate.

[0010] Specifically, this makes it convenient to remove the upper template.

[0011] Optionally, the bottom surface of the upper template and the top surface of the lower template are respectively provided with upper and lower corresponding positioning columns and positioning grooves.

[0012] Specifically, there are three positioning posts and three positioning slots. The three positioning posts are respectively located on the left and right sides of the front end and the right side of the rear end of the upper template. The three positioning slots are respectively located on the left and right sides of the front end and the right side of the rear end of the lower template.

[0013] Optionally, when the protrusion of the upper template is inserted into the guide groove of the vertical plate, the two protrusions of the upper template can be respectively inserted into the two vertical limiting grooves in front and behind the vertical column.

[0014] The utility model also includes other components that enable a conveniently positioned aluminum profile hot extrusion die to be used normally, which are all conventional technical means in the art. In addition, the devices or components not limited in the utility model all adopt conventional technical means in the art.

[0015] The working principle of the utility model is that when positioning the upper template and the lower template, the specific steps are: installing the upper template, that is, the through hole of the upper template is sleeved on the top of the column, the two columns in the through hole are respectively inserted into the vertical limiting grooves on the corresponding sides, and the convex block of the upper template is inserted into the guide groove of the vertical plate. At this time, the upper template and the lower template can be opposite to each other up and down, and the insert block and the slot are also opposite to each other up and down, and then the upper template is moved downward along the vertical limiting groove of the column and the guide groove of the vertical plate until the three positioning columns of the upper template are respectively inserted into the three positioning grooves of the lower template, that is, the upper template and Positioning of the lower template; after the extrusion of the previous aluminum billet is completed, lift the upper template until the two protrusions move to the position of the annular limit groove, rotate the upper template clockwise along the axial direction of the column to make the two protrusions slide into the annular limit groove, and use the matching relationship between the protrusions and the annular limit groove to support the upper template on the column, and then start processing the next aluminum billet, rotate the upper template counterclockwise to make the two protrusions slide into the corresponding vertical limit grooves respectively, and at the same time, the protrusions are inserted into the guide grooves of the vertical plates, lower the upper template, complete the positioning, and start the next round of extrusion operation.

[0016] The beneficial effects of the utility model are simple structure, low cost, and the use of columns and vertical plates facilitates the rapid positioning of the upper template and the lower template. The matching relationship between the annular limit grooves of the columns and the convex columns of the upper template can also be used to provide support for the upper template. The next round of positioning and extrusion operations can be started without removing the upper template, thereby reducing assembly time and improving production efficiency.
