Description

Technical Field

[0001] This utility model relates to the technical field of heat insulation cover cutting fixtures, and more specifically to a heat insulation cover cutting die. Background Technology

[0002] Heat shields effectively isolate high temperatures in automotive powertrain systems, protecting surrounding components and improving vehicle performance and driving comfort. Choosing the right heat shield and using it correctly can significantly improve thermal management and noise control in the engine compartment.

[0003] Because heat shields need to be compatible with automotive powertrain systems, their shapes are often uneven. During production, heat shields typically have an edge allowance. Currently, the common practice is to manually trim this edge allowance after production to create the final product. However, this method is inefficient, and the trimming quality cannot be guaranteed, resulting in low product quality consistency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low efficiency, unreliable cutting quality, and low product quality stability caused by manual cutting of the edges of heat insulation covers in the prior art.

[0005] To solve the above problems, this utility model provides a drawing and cutting die for a heat insulation cover, including a drawing and cutting block, a fixed die platform located below, and a movable die platform located above. The lower side of the movable die platform is provided with a floating plate that can move up and down. A vertically arranged thrust spring is provided between the floating plate and the movable die platform. The upper side of the fixed die platform is provided with a fixed die cavity with a cutting opening. The drawing and cutting block is slidably disposed on the upper side of the fixed die platform and has a cutting edge facing the cutting opening. The fixed die platform is provided with a reset member for pushing the drawing and cutting block away from the cutting opening. The movable die platform is provided with a push block facing the drawing and cutting block. When the movable die platform descends, the push block pushes the drawing and cutting block closer to the cutting opening so that the cutting edge cuts the workpiece between the die cavity and the fixed die cavity.

[0006] The above solution supports the finished heat insulation cover or similar workpieces through the fixed mold cavity of the fixed mold table. Then, as the moving mold table descends, the pressing cavity of the floating plate presses against the upper side of the workpiece, fixing it between the pressing cavity and the fixed mold cavity. As the moving mold table continues to descend, the floating plate is pushed towards the moving mold table by the workpiece, compressing the thrust spring. The pushing block of the moving mold table, as it continues to descend, pushes the cutting block closer to the cutting edge, allowing the cutting edge to cut the workpiece between the pressing cavity and the fixed mold cavity, thus achieving automatic edge trimming of the workpiece. Compared with existing technologies, the above solution achieves automatic edge trimming of the workpiece through the moving mold table, offering high efficiency and stable trimming quality, and possesses good practicality.

[0007] In an improved embodiment, the fixed mold cavity is provided with two cutting openings located on both sides of two pulling cutting blocks. There are two pulling cutting blocks, which are slidably connected to the upper side of the fixed mold table in a transverse direction. The reset member is a spring that acts on the two pulling cutting blocks and pushes them closer together. The push block is disposed between the two pulling cutting blocks and is used to push them apart. Thus, when the two pulling cutting blocks separate, the workpiece at the two cutting openings of the fixed mold cavity is cut. When the two pulling cutting blocks approach each other, the pulling cutting blocks disengage from the cutting openings.

[0008] In an improved embodiment, the lower end of the push block gradually narrows downward to form a cone shape, thereby stably pushing the separation of the two pull-cutting blocks when the push block moves downward.

[0009] In an improved embodiment, the fixed mold stage has two fixed mold cavities arranged at intervals, and two cutting blocks are located between the two fixed mold cavities, so that the moving mold stage can cut two workpieces in one descent, further improving efficiency.

[0010] In an improved embodiment, a vertical sliding rod is connected to the lower side of the moving mold platform, and the floating plate is provided with a sliding hole that is slidably connected to the sliding rod. The bottom end of the sliding rod is provided with a limiting part with an outer diameter larger than that of the sliding hole, thereby achieving the guiding function of the floating plate moving up and down through the sliding cooperation between the sliding hole and the sliding rod.

[0011] In an improved embodiment, the thrust springs are multiple and arranged in a matrix, with the upper end of each thrust spring abutting against the moving mold table and the lower end abutting against the floating plate, thereby enabling the thrust springs to apply a downward thrust to the floating plate more evenly.

[0012] In an improved embodiment, the fixed mold platform is provided with an upwardly extending guide post, and the moving mold platform is provided with a guide hole that is slidably connected to the guide post, thereby achieving the guiding function of the moving mold platform during lifting and lowering through the sliding fit between the guide hole and the guide post.

[0024] Please see Figures 1-5The present invention provides a heat insulation cover drawing die, including a drawing block 3, a fixed die platform 1 located below, and a movable die platform 2 located above. The lower side of the movable die platform 2 is provided with a floating plate 4 that can move up and down. A vertically arranged thrust spring 5 is provided between the floating plate 4 and the movable die platform 2. The upper side of the fixed die platform 1 is provided with a fixed die cavity 11 and a cutting opening 12. The drawing block 3 is slidably arranged on the upper side of the fixed die platform 1 and the drawing block 3 is provided with a cutting edge 31 facing the cutting opening 12. The fixed die platform 1 is provided with a reset member 13 for pushing the drawing block 3 away from the cutting opening 12. The movable die platform 2 is provided with a push block 21 facing the drawing block 3. When the movable die platform 2 descends, the push block 21 pushes the drawing block 3 closer to the cutting opening 12 so that the cutting edge 31 cuts the workpiece between the pressing die cavity 41 and the fixed die cavity 11.

[0025] The above solution supports the completed heat insulation cover or similar workpieces through the fixed mold cavity 11 of the fixed mold table 1. Then, when the moving mold table 2 descends, the pressing mold cavity 41 of the floating plate 4 presses against the upper side of the workpiece, fixing the workpiece between the pressing mold cavity 41 and the fixed mold cavity 11. As the moving mold table 2 continues to descend, the floating plate 4 is pushed towards the moving mold table 2 by the workpiece, compressing the thrust spring 5. The push block 21 of the moving mold table 2, as it continues to descend, pushes the cutting block 3 closer to the cutting opening 12, causing the cutting edge 31 to cut the workpiece between the pressing mold cavity 41 and the fixed mold cavity 11, thus achieving automatic edge trimming of the workpiece. Compared with existing technologies, the above solution achieves automatic edge trimming of the workpiece through the moving mold table 2, with high efficiency and stable trimming quality, possessing good practicality.

[0026] Combination Figure 5 As shown, in this embodiment, the fixed mold cavity 11 is provided with two cutting openings 12, and the two cutting openings 12 are respectively located on both sides of the two pulling cutting blocks 3. There are two pulling cutting blocks 3, which are slidably connected to the upper side of the fixed mold table 1 in the transverse direction. The reset member 13 is a spring, and the reset member 13 acts on the two pulling cutting blocks 3 and pushes the two pulling cutting blocks 3 closer to each other. The push block 21 is arranged between the two pulling cutting blocks 3 and is used to push the two pulling cutting blocks 3 to separate from each other. Thus, when the two pulling cutting blocks 3 separate from each other, the workpiece at the two cutting openings 12 of the fixed mold cavity 11 will be cut. When the two pulling cutting blocks 3 are close to each other, the pulling cutting blocks 3 will disengage from the cutting openings 12.

[0027] Combination Figure 4 As shown, in this embodiment, the lower end of the push block 21 gradually narrows downward to form a cone shape, so that when the push block 21 moves downward, it can stably push the two pulling and cutting blocks 3 to separate.

[0028] Combination Figure 5As shown, in this embodiment, the fixed mold stage 1 has two fixed mold cavities 11 arranged at intervals, and the two pulling and cutting blocks 3 are located between the two fixed mold cavities 11, so that the moving mold stage 2 can cut two workpieces in one drop, further improving efficiency.

[0029] In this embodiment, a vertical sliding rod 22 is connected to the lower side of the moving mold platform 2, and the floating plate 4 is provided with a sliding hole 42 that is slidably connected to the sliding rod 22. The bottom end of the sliding rod 22 is provided with a limiting part with an outer diameter larger than the sliding hole 42, so that the sliding hole 42 and the sliding rod 22 can be slidably engaged to guide the floating plate 4 to move up and down.

[0030] In this embodiment, there are multiple thrust springs 5 ​​arranged in a matrix. The upper end of the thrust spring 5 abuts against the moving mold table 2 and the lower end abuts against the floating plate 4, so that the thrust spring 5 can apply a downward thrust to the floating plate 4 more evenly.

[0031] In this embodiment, the fixed mold platform 1 is provided with an upwardly extending guide post 14, and the moving mold platform 2 is provided with a guide hole 23 slidably connected to the guide post 14. Thus, the sliding engagement between the sliding hole 42 and the guide post 14 achieves the guiding function of the moving mold platform 2 during lifting and lowering. The moving mold platform 2 is driven by an external cylinder or hydraulic cylinder to achieve lifting and lowering, which is prior art and will not be described in detail here.
