However, the above application documents are more cumbersome when limiting the workpiece, thereby reducing the processing efficiency of the EMU pantograph air deflector mold. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and propose a pantograph deflector mold for a motor vehicle. The utility model cooperates with the pressing assembly and the transmission assembly so that when the workpiece is placed in the mold, the workpiece moves downward, so that the workpiece can push the protrusion to shrink inward, and at this time the pressing part can gradually move closer to the workpiece to clamp the workpiece to a certain extent, reducing the cumbersome operation steps, so that the workpiece can be fixed by moving itself, which is more convenient and improves efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A mold body, the inner side of which is provided with a molding portion that fits with the pantograph guide cover;

[0009] A cavity configured inside the mold body;

[0010] A mounting plate 1 and a mounting plate 2, both of which are mounted inside the cavity, and the mounting plate 1 is arranged perpendicularly to the mounting plate 2;

[0011] A cooling mechanism is installed on the surface of the first mounting plate, a pressing assembly is connected through the surface of the first mounting plate, and a transmission assembly matched with the pressing assembly is connected between the second mounting plates.

[0015] The connector 1 and the connector 2 are both connected through the surface of the mounting plate 1, the pressing part is installed at one end of the connector 1, and the protrusion is installed at one end of the connector 2 and protrudes out of the mold body.

[0016] The utility model is further configured that the transmission assembly includes: a rotating member and a gear;

[0017] The rotating member is connected between the two mounting plates, and the gear is mounted on the surface of the rotating member.

[0018] The utility model is further configured that the surfaces of the first connecting member and the second connecting member are both structured with teeth meshing with gears.

[0019] The utility model is further configured that the surfaces of the second mounting plate are both installed with limiting frames, and the surface of the rotating member is installed with a torsion spring located in the limiting frame.

[0020] The utility model is further configured that a base is fixed on the lower part of the mold body.

[0021] The beneficial effects of the utility model are as follows: the utility model cooperates with the pressing assembly and the transmission assembly, so that when the workpiece is placed in the mold, due to the downward movement of the workpiece, the workpiece can push the protrusion to shrink inward, and at this time the pressing part can gradually move closer to the workpiece to clamp the workpiece to a certain extent, reducing cumbersome operating steps, so that the workpiece can be fixed by moving itself, which is more convenient and improves efficiency.

[0022] 1. The pantograph deflector mold of the EMU is provided with a pressing assembly and a transmission assembly to cooperate, so that when the workpiece is placed in the mold for processing, the workpiece can push the protrusion to shrink inward due to the downward movement of the workpiece, and the protrusion can drive the pressing part to move synchronously in the opposite direction through the transmission assembly. At this time, the pressing part can gradually move closer to the workpiece to clamp the workpiece to a certain extent, reducing cumbersome operating steps, so that the movement of the workpiece itself can be fixed, which is more convenient and improves efficiency.

[0023] 2. The pantograph air deflector mold of the EMU is provided with a cooling mechanism. After the pantograph air deflector is processed, a certain amount of heat is easily generated around it. At this time, due to the existence of heat, it is inconvenient for personnel to take and place the workpiece. Under the action of the cooling mechanism, after the cooling part is started, air can be drawn from the air inlet end and discharged into the molding part from the air outlet end, so as to quickly cool the processed workpiece, avoid the need to spend a long time waiting for cooling, and save time.

[0033] Reference Figure 1-4 A pantograph air deflector mold for a motor vehicle comprises: a mold body 1, the inner side of which is configured with a molding part 2 that fits the pantograph air deflector, which is the basic frame of the entire mold, responsible for supporting and fixing various internal components, and can ensure that the air deflector can accurately replicate the shape of the mold during the molding process, thereby ensuring the accuracy and quality of the product; a cavity 3, which is configured inside the mold body 1, and provides space for the installation of components through the cavity 3; a mounting plate 1 5 and a mounting plate 2 17, which are both installed inside the cavity 3, and the mounting plate 1 5 is vertically arranged with the mounting plate 2 17, and the mounting plate 1 5 and the mounting plate 2 17 are installed in the cavity 3. The use of the mounting plate 15 can improve the strength of the mold body 1, and is also convenient for supporting and installing the components through the mounting plate 15 and the mounting plate 2 17; a cooling mechanism is installed on the surface of the mounting plate 15, and under the action of the cooling mechanism, a certain cooling and temperature reduction treatment can be performed on the workpiece after processing and forming, saving time; a pressing component is connected through the surface of the mounting plate 5, and a transmission component matched with the pressing component is connected between the mounting plates 2 17, and the force of the workpiece during the downward movement can be easily transmitted to the position of the pressing component through the transmission component, so that the pressing component can clamp and limit the workpiece to a certain extent, and the operation is convenient.

[0034] Specifically, refer to Figure 2-3The cooling mechanism includes: a cooling member 6, an air inlet end 14 and an air outlet end 7; the cooling member 6 is installed on the surface of the mounting plate 5, the air inlet end 14 is connected to the input end of the cooling member 6, the air outlet end 7 is connected to the output end of the cooling member 6 and is connected to the forming portion 2. Through this embodiment, under the action of the cooling mechanism, after the cooling member 6 is started, air can be drawn from the air inlet end 14 and discharged from the air outlet end 7 into the forming portion 2, thereby quickly cooling the processed workpiece, avoiding the need to spend a long time waiting for cooling, and saving time.

[0035] Specifically, refer to Figure 2 The pressing assembly includes: a connector 12, a connector 2 13, a pressing portion 8 and a protrusion 9; the connector 12 and the connector 2 13 are both connected through the surface of the mounting plate 1 5, so that the connector 12 and the connector 2 13 can move horizontally in the mounting plate 1 5 to transmit the action, the pressing portion 8 is installed at one end of the connector 12, and the protrusion 9 is installed at one end of the connector 2 13 and protrudes out of the mold body 1. Through this embodiment, the workpiece is placed at the position of the forming portion 2 of the mold body 1, so that the workpiece will first contact the protruding protrusion 9 during the downward movement, and as the workpiece is guided by the inclined forming portion 2, the protrusion 9 gradually moves inward and drives the connector 2 13 to move together.

[0036] Specifically, refer to Figure 2-3 The transmission assembly includes: a rotating member 10 and a gear 11; the rotating member 10 is connected between the mounting plates 17, and the gear 11 is installed on the surface of the rotating member 10. Through this implementation, the connecting member 13 can drive the gear 11 to rotate under the action of the rotating member 10 during the activity. At this time, the gear 11 can push the connecting member 12 and the pressing part 8 to move in the opposite direction of the connecting member 13. The pressing part 8 can gradually move closer to the workpiece to clamp the workpiece to a certain extent, reducing the cumbersome operation steps, so that the movement of the workpiece itself can be fixed.

[0037] Furthermore, the surfaces of connecting member 12 and connecting member 2 13 are both constructed with teeth that mesh with gear 11. Through this design, it is ensured that they can mesh accurately. This precise meshing reduces energy loss in the transmission process, thereby improving transmission efficiency. Compared with other types of connection methods (such as friction connection, pin connection, etc.), gear transmission has higher transmission ratio accuracy and more stable transmission performance. Through tooth meshing, the slippage in the transmission process can be effectively reduced.

[0038] Furthermore, a limiting frame 16 is installed on the surface of the second mounting plate 17, a torsion spring 15 located in the limiting frame 16 is installed on the surface of the rotating member 10, and a base 4 is fixed to the lower part of the mold body 1. Through this design, the base 4 can provide stable support for the mold body 1, and can drive the torsion spring 15 to be compressed to a certain extent during the rotation of the rotating member 10. Then, when the workpiece is taken out, the torsion spring 15 can restore its elasticity and drive the pressing assembly to reset through the transmission assembly, so as to facilitate the clamping and limiting processing of subsequent workpieces and improve flexibility.

[0039] Working principle: When using the utility model, first place the workpiece at the position of the forming part 2 of the mold body 1, so that the workpiece will first contact the protruding block 9 during the downward movement, and as the workpiece is guided by the inclined forming part 2, the block 9 gradually moves inward, at this time, the block 9 will drive the gear 11 to rotate through the connecting piece 2 13, and the gear 11 drives the connecting piece 12 and the pressing part 8 to move, and the pressing part 8 can gradually move closer to the workpiece to clamp the workpiece to a certain extent, reducing the cumbersome operation steps, so that the movement of the workpiece itself can be fixed, which is more convenient and improves efficiency. After the pantograph guide cover is processed, a certain amount of heat is easily generated around it. At this time, due to the presence of heat, it is inconvenient for personnel to pick up and place the workpiece, and under the action of the cooling mechanism, the cooling part 6 can draw air from the air inlet end 14 after being started and discharge it into the forming part 2 from the air outlet end 7, thereby quickly cooling the processed workpiece, avoiding the need to spend a long time waiting for cooling, and saving time.
