Description

Technical Field

[0001] This utility model relates to the technical field of modules, and in particular to a precision extrusion die for producing aluminum profiles for children's foot pedals. Background Technology

[0002] Extrusion dies are a type of forming die, and their discharge method is achieved through extrusion. They are widely used in the production of various profile structures. For example... Figure 1 The image shows a cross-sectional view of an aluminum profile used for producing children's foot pedals. During the manufacturing process of children's foot pedals, one end needs to be bent. However, the aluminum profiles for children's foot pedals produced by existing ordinary molds are prone to breakage when bent, making it impossible to perform secondary processing. Utility Model Content

[0003] The purpose of this invention is to provide a precision extrusion die for producing aluminum profiles for children's foot pedals, which has the advantage of improving the performance of aluminum profiles.

[0004] To achieve the above objectives, the solution of this utility model is:

[0005] A precision extrusion die for producing aluminum profiles for children's foot pedals includes a die body with a welding chamber recessed at the upper end of the die body. The welding chamber has a forming hole that runs vertically through it, and the outline of the forming hole corresponds to the outline of the aluminum profile for children's foot pedals.

[0006] The forming hole includes a horizontal hole extending horizontally to the left and right, and two vertical holes that are spaced apart to the left and right and extend vertically forward and backward, connected to the front side of the horizontal hole; the width of the vertical hole is greater than the width of the horizontal hole.

[0007] The welding chamber is arranged around the outer contour of the forming hole. The welding chamber is divided into a horizontal chamber and two vertical chambers corresponding to the forming hole. The left and right ends of the horizontal chamber are gradually expanded outward from the front and back sides. The bottom wall of the vertical chamber has a bulging flow block, which is located on the outer edge of the vertical hole away from the horizontal hole.

[0008] Furthermore, the flow-blocking block is attached to the side wall of the welding chamber and spaced apart from the edge of the vertical hole.

[0009] Furthermore, the rear side of the flow-blocking block near the transverse hole has an inclined surface, and the angle between the inclined surface and the side of the flow-blocking block near the vertical hole is an acute angle, and the inclined surface and the side of the flow-blocking block near the vertical hole are rounded.

[0010] Furthermore, the flow-blocking block is located within the vertical cavity, and the rear end of the flow-blocking block extends into the horizontal cavity and is spaced apart from the horizontal hole; the inclined surface is located at the rear end of the flow-blocking block and connected to the front sidewall of the horizontal cavity.

[0011] Furthermore, the height of the flow-blocking block is one-third of the depth of the welding chamber.

[0012] Furthermore, the front-to-back width of the left and right ends of the transverse chamber is greater than the front-to-back width of the middle part of the transverse chamber; the top opening of the transverse chamber is a constricted opening, and the left-to-right width of the bottom wall of the transverse chamber is greater than the left-to-right width of the top opening of the transverse chamber.

[0013] Furthermore, the corners of the sidewalls of the welding chamber are rounded.

[0014] After adopting the above technical solution, when using the precision extrusion die for production, since the width of the transverse hole is relatively small, by setting the two ends of the transverse cavity of the welding chamber to an outward expansion shape, the volume of the transverse cavity can be increased, the metal flow rate can be increased, thereby increasing the metal flow velocity towards the narrower transverse hole; and by setting a flow-blocking block on the outside of the wider vertical hole, the metal flow velocity towards the vertical hole can be slowed down, thereby balancing the overall metal flow velocity towards the forming hole in the welding chamber, ensuring that the formed profile structure is stable and reliable, with uniform strength, improving the performance of the aluminum profile, and avoiding breakage during subsequent bending operations.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] like Figures 2 to 5 As shown, a precision extrusion die for producing aluminum profiles for children's foot pedals in this embodiment includes a die body 1. The upper end of the die body 1 is recessed with a welding chamber 11. The welding chamber 11 has a forming hole 12 that runs vertically through it. The outline of the forming hole 12 corresponds to the outline of the aluminum profile 10 for children's foot pedals.

[0023] The forming hole 12 includes a horizontal hole 121 extending horizontally to the left and right, and two vertical holes 122 that are spaced apart to the left and right and extend vertically forward and backward, connected to the front side of the horizontal hole 121; the width of the vertical hole 122 is greater than the width of the horizontal hole 121; the horizontal hole 121 is used for forming. Figure 1 The child pedal aluminum profile 10 shown has a horizontal plate 101, while two vertical holes 122 are used to form two vertical plates 102 of the child pedal aluminum profile 10.

[0024] The welding chamber 11 is arranged around the outer contour of the forming hole 12. The welding chamber 11 is divided into a horizontal chamber 111 and two vertical chambers 112 corresponding to the forming hole 12. The left and right ends of the horizontal chamber 111 are gradually expanded outward from the front and back sides. The bottom wall of the vertical chamber 112 protrudes to form a flow-blocking block 13, which is located on the outer edge of the vertical hole 122 away from the horizontal hole 121.

[0025] Therefore, when using this precision extrusion die for production, since the width of the transverse hole 121 is relatively small, by setting the two ends of the transverse cavity 111 of the welding chamber 11 to be outwardly flared, the volume of the transverse cavity 111 can be increased, the metal flow rate can be increased, thereby increasing the metal flow velocity towards the narrower transverse hole 121; and by setting the flow-blocking block 13 on the outside of the wider vertical hole 122, the metal flow velocity towards the vertical hole 122 can be slowed down, thereby balancing the overall metal flow velocity towards the forming hole 12 in the welding chamber 11, ensuring that the formed profile structure is stable and reliable, with uniform strength, improving the performance of the aluminum profile, and avoiding breakage during subsequent bending operations.

[0026] Specifically, the flow-blocking block 13 can be closely attached to the side wall of the welding chamber 11 and spaced at the edge of the vertical hole 122. Furthermore, the rear side of the flow-blocking block 13 near the transverse hole 121 can have a slope 131, the angle between the slope 131 and the side 132 of the flow-blocking block near the vertical hole being an acute angle, and the slope 131 and the side 132 of the flow-blocking block near the vertical hole are rounded. The slope 131 is provided to serve a guiding function, facilitating the flow of metal.

[0027] In this embodiment, the flow-blocking block 13 is located in the vertical chamber 112, and the rear end of the flow-blocking block 13 extends into the horizontal chamber 111 and is spaced apart from the horizontal hole 121; the inclined surface 131 is located at the rear end of the flow-blocking block 13 and is connected to the front side wall 1111 of the horizontal chamber 111, which also facilitates the flow of metal.

[0028] Specifically, the height of the flow-blocking block 13 can be one-third of the depth of the welding chamber 11, which can have a better flow-blocking and deceleration effect on the forming hole 12.

[0029] The front-to-back width H1 at both ends of the transverse chamber 111 is greater than the front-to-back width H2 at the middle of the transverse chamber 111; the top opening 1112 of the transverse chamber 111 is a constricted opening, and the left-to-right width H3 of the bottom wall of the transverse chamber 111 is greater than the left-to-right width H4 of the top opening of the transverse chamber 111. This is to facilitate the full fusion of the metals in the welding chamber 11.

[0030] Furthermore, the corners of the side walls of the welding chamber 11 can be rounded to facilitate metal flow.
