DETAILED DESCRIPTION

[0029] The following will be further illustrated in detail with reference to the accompanying drawings. Figures 1-5 The application is further illustrated in detail.

[0030] The embodiment of the application discloses an integrated die for forming and cutting of automobile carpet.

[0031] With reference to Figure 1 and Figure 2 An integrated die for forming and cutting of automobile carpet, comprising an upper die 1 and a lower die 2 installed on a press device, the lower die 2 is provided with a placing groove 21, and the automobile carpet is arranged in the placing groove 21. The upper die 1 is arranged in correspondence with the lower die 2, and the upper die 1 and the lower die 2 can cut the edge of the automobile carpet during clamping. The placing groove 21 is provided with a cooling pipe 3, one end of the cooling pipe 3 extends into the placing groove 21, and the other end is connected with an external gas source. The gas source can be a blowing device, a pressure tank or the like, and is mainly used for providing gas.

[0032] With reference to Figure 1 and Figure 2The bottom of the lower die 2 is provided with an exhaust hole 22 for air exhaust. Before cutting, the cooling gas is blown into the placing groove 21 through the cooling pipe 3 to cool the automobile carpet. After the automobile carpet is heated and shaped, it will deform due to thermal expansion and contraction, so that cutting failure may occur during cutting. By blowing cooling gas into the placing groove 21, the automobile carpet is cooled, thereby reducing the thermal expansion and contraction phenomenon after cutting and improving the qualified rate during cutting of the automobile carpet.

[0033] With reference to Figure 2 and Figure 3 , the cooling pipe 3 comprises a main pipe 32 and a branch pipe 31. The main pipe 32 extends along the circumference of the placing groove 21. The branch pipe 31 is uniformly spaced along the length direction of the main pipe 32. One end of the branch pipe 31 communicates with the main pipe 32, and the other end extends towards the opening of the placing groove 21. The arrangement of the plurality of branch pipes 31 enables the cooling pipe 3 to cool different positions of the automobile carpet, thereby improving the cooling efficiency and effect of the automobile carpet.

[0034] With reference to Figure 2 and Figure 3 , the side wall of the placing groove 21 perpendicular to the ground is provided with a mounting groove 24, and the cooling pipe 3 is fixedly connected in the mounting groove 24 to facilitate installation of the cooling pipe 3. The side wall of the placing groove 21 is provided with a limiting groove 23 corresponding to the position of the branch pipe 31. The limiting groove 23 is inclined downward along the horizontal direction and communicates with the mounting groove 24. The branch pipe 31 is embedded in the limiting groove 23. The limiting groove 23 can limit the position of the branch pipe 31, thereby reducing the position change of the flexible branch pipe 31.

[0035] With reference to Figure 4 and Figure 5 , the lower die 2 is provided with a material receiving box 4. The material receiving box 4 has a ring structure and is sleeved on the outside of the lower die 2. The side of the material receiving box 4 away from the ground is provided with an opening.

[0036] With reference to Figure 4 and Figure 5 , the lower die 2 is provided with a support plate 51. The support plate 51 is located below the material receiving box 4 and is used to support the material receiving box 4. The material receiving box 4 can slide in the vertical direction. Sliding the material receiving box 4 in the vertical direction can quickly realize quick disassembly and connection between the material receiving box 4 and the lower die 2, thereby further facilitating cleaning of the waste material.

[0037] With reference to Figure 4 and Figure 5The side of the receiving box 4 close to the ground is provided with a positioning assembly 5, the positioning assembly 5 is provided corresponding to a support plate 51, the positioning assembly 5 comprises a plug rod 52 and a limiting block 53. One end of the plug rod 52 is vertically welded on the side of the receiving box 4 close to the ground. The support plate 51 is provided with a plug hole 54 corresponding to the plug rod 52, one end of the plug rod 52 away from the receiving box 4 is inserted into the plug hole 54, the limiting block 53 is located on the side of the support plate 51 away from the receiving box 4, the plug rod 52 is provided with a sliding groove corresponding to the limiting block 53, and the limiting block 53 is slidably connected in the sliding groove in a direction perpendicular to the length of the plug rod 52. The side of the limiting block 53 away from the ground is in abutment with the support plate 51, so that the plug rod 52 can be limited, thereby improving the stability of the receiving box 4 after installation. The sliding limiting block 53 makes the limiting block 53 sink into the sliding groove, so that the limiting of the plug rod 52 can be cancelled, and the receiving box 4 is convenient to disassemble. The positioning assembly 5 can be provided in multiple groups uniformly and circumferentially along the lower mold 2, so as to further improve the stability of the receiving box 4 after installation.

[0038] With reference to Figure 4 and Figure 5 , the positioning assembly 5 further comprises a driving rod 55, the plug rod 52 is internally provided with a sliding cavity 56 in communication with the sliding groove, and the driving rod 55 is slidably fitted in the sliding cavity 56 in a vertical direction. The driving rod 55 is provided with an avoiding groove 57, when the avoiding groove 57 is in position corresponding to the limiting rod, the limiting block 53 can move into the sliding groove, so as to cancel the limiting of the plug rod 52. When the avoiding groove 57 is in position staggered with the sliding groove, the limiting block 53 is in abutment with the side wall of the driving rod 55, the driving rod 55 limits the sliding of the limiting block 53, and the stability of the limiting of the plug rod 52 by the limiting block 53 is improved.

[0039] With reference to Figure 4 and Figure 5 , the driving rod 55 is provided with a locking assembly 6, the locking assembly 6 comprises a locking rod 61 and an elastic member 63, the locking rod 61 is slidably connected on the driving rod 55 in a direction perpendicular to the length of the driving rod 55, the side wall of the sliding cavity 56 is provided with a clamping groove 62, one end of the locking rod 61 can be inserted into the clamping groove 62, and the driving rod 55 is limited.

In the embodiment, the elastic member 63 is a spring, one end of the spring is connected with the driving rod 55, and the other end is connected with the locking rod 61. One end of the locking rod 61 close to the clamping groove 62 is provided with a spherical surface, and the spherical surface is embedded in the clamping groove 62. When a sufficient force is applied to the driving rod 55, the locking rod 61 can be separated from the clamping groove 62 under the action of the spherical surface, and the elastic force of the elastic member 63 is overcome.
