Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, and more specifically to an extrusion die for automotive end plate profiles. Background Technology

[0002] End plate profiles refer to profiles used in automotive end plates, which are part of the vehicle body structure; extrusion dies are molds used to form these profiles through an extrusion process; extrusion dies heat metal materials (such as aluminum alloys, steel, etc.) and use high pressure to extrude them through the mold to form the required shape and size.

[0003] In mold design, if the inlet and outlet holes are not aligned from a top-down perspective, the material distribution inside the mold will be uneven; the obstructed material flow path will reduce molding efficiency, and the mold will need more time to complete the extrusion molding process, thereby reducing production efficiency and increasing the production cycle. Utility Model Content

[0004] The purpose of this utility model is to provide an extrusion die for automotive end plate profiles in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0018] like Figures 1 to 3 As shown, this utility model proposes: an extrusion die for automotive end plate profiles, including an upper die, to which a lower die is connected. An inlet bridge is provided on one side of the upper die, and four second inlet holes are spaced vertically near the center of the inlet bridge. Four first inlet holes are spaced vertically on both sides of the inlet bridge. A die core rod is connected between the four second inlet holes. An outlet bridge is provided on the side of the lower die away from the upper die, and several outlet holes are provided between the outlet bridges. A welding chamber is provided at the connection between the lower die and the upper die.

[0019] The directions of the feed inlet and the discharge outlet correspond in a top-view angle, and the directions of the feed bridge and the discharge bridge also correspond in a top-view angle.

[0020] The diameter of the first feed hole is larger than that of the second feed hole.

[0021] The four second feed holes are connected by a mold core rod.

[0022] The upper mold is provided with four pin holes for secure connection.

[0023] The upper mold is also provided with two keyways distributed vertically.

[0024] The working principle of this embodiment is as follows:

[0025] The mold consists of an upper mold and a lower mold, which are securely connected by pin holes and keyways. The design of the pin holes and keyways ensures that the mold will not loosen or shift during the closing process, thus guaranteeing the stability and accuracy of the mold. After the mold closes, the inlet and outlet taper bridges form a complete extrusion chamber, providing a channel for the flow of metal material. The metal material enters from the inlet end of the mold and first passes through the inlet taper bridge on one side of the upper mold. The inlet taper bridge is provided with a first inlet hole and a second inlet hole.

[0026] The first inlet hole is located on both sides of the inlet bridge, spaced vertically, and has a larger diameter to guide most of the metal material into the mold. The second inlet hole is located in the central area of ​​the inlet bridge, spaced vertically, and has a smaller diameter to assist the flow of metal material. In addition, the mold core rod connects the four second inlet holes, which supports and guides the flow of metal material, ensuring that the metal material is evenly distributed inside the mold.

[0027] Metal materials are forced through the extrusion chamber of a die under high pressure by an extruder at high temperature. The metal materials enter the die through the inlet hole of the inlet bridge and flow out through the outlet hole of the outlet bridge, ultimately forming the desired end plate profile shape. The inlet and outlet holes correspond to each other from a top-view angle, ensuring a smooth path for the metal materials during flow, reducing flow resistance, and improving forming efficiency.

[0028] The extruded profile is rapidly cooled by the cooling system inside the mold (usually a cooling water channel) to set the material. The design of the cooling system can effectively control the cooling rate of the profile and avoid deformation or internal stress caused by cooling too fast or too slow. After forming, the mold is opened and the upper and lower molds are separated. The formed end plate profile is taken out from the discharge end and enters the subsequent processing or inspection process.

[0029] The control method of this utility model is to control it by manually starting and stopping the switch. The wiring diagram of the power component and the power supply are common knowledge in this field. Since this utility model is mainly used to produce automotive end plate profiles, the control method and wiring layout will not be explained in detail.
