Description

Technical Field

[0001] This utility model relates to the field of automotive trim processing technology, and in particular to a trim trimming mold. Background Technology

[0002] In the production of automotive exterior trim strips, to ensure smooth molding, a margin is left at the ends of the trim strips. After molding, this excess material needs to be removed through a punching process. However, the traditional process, which uses a die with the cutter set in the upper mold for top-down punching, means the cutter moves from the outer surface of the trim strip towards the mounting surface. This can easily cause the outer surface of the trim strip to collapse and deform at the cut. This defect necessitates an additional repair step before grinding and polishing to fix the collapse. However, the process of repairing the collapsed outer surface not only occupies production equipment for a long time but also consumes a large amount of repair material, resulting in reduced production efficiency and material utilization. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a trimming mold for trimming strips, so that the cut edge of the trim strip's outer surface forms a raised burr edge and avoids the formation of a collapse at the cut edge of the outer surface.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a trimming mold for decorative strips, including a lower mold, wherein the mold closing surface of the lower mold is provided with a lower mold core; The upper mold is provided with a pressure block that is adapted to the lower mold core; The cutting tool is slidably disposed on the lower mold core, and the sliding direction of the cutting tool is parallel to the mold closing direction of the lower mold and the upper mold.

[0005] Furthermore, the mold closing surface of the lower mold is provided with a slider that moves toward the tool direction, and the slider is provided with a first inclined surface that abuts against the bottom of the tool.

[0006] Furthermore, the bottom of the cutting tool is provided with a second inclined surface that is adapted to the first inclined surface.

[0007] Furthermore, the aforementioned trimming mold also includes a first connector and a first spring. The first connector passes through the lower mold and is connected to the cutting tool. The elastic end of the first spring abuts against the end of the first connector away from the cutting tool. Alternatively, the first spring is connected between the cutting tool and the lower die.

[0008] Furthermore, the lower mold closing surface is provided with a first limiting block, and a gap is left between the slider and the first limiting block; the upper mold is provided with a push block located above the gap, and the thickness of the push block is greater than the width of the gap.

[0009] Furthermore, the end of the slider facing the upper mold is provided with a third inclined surface that slopes toward the gap direction.

[0010] Furthermore, the push block is provided with a fourth inclined surface that is adapted to the third inclined surface.

[0011] Furthermore, the aforementioned trimming mold also includes a second connector and a second spring; the second connector passes through the first limiting block and is connected to the slider, and the elastic end of the second spring abuts against the end of the second connector away from the slider. Alternatively, the second spring can be positioned between the slider and the first limiting block.

[0012] Furthermore, the closing surface of the lower mold is provided with a second limiting block.

[0013] Furthermore, the lower mold core is provided with a guide groove, and the cutting tool is slidably disposed on the guide groove.

[0014] The beneficial effect of this utility model is that by modifying the cutting tool to the lower die, during the punching process, the pressure block and the lower die core cooperate to clamp the end of the trim strip, and drive the cutting tool to cut off the excess material at the end of the trim strip from bottom to top, thereby preventing the appearance of the trim strip from collapsing and deforming.

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 3 As shown, this application provides a trimming mold for trimming trimming strips, including a lower mold 1, an upper mold 2 and a cutting tool 3. The lower mold 1 has a lower mold core 11 on its mating surface; the upper mold 2 has a pressure block 21 adapted to the lower mold core 11; the cutting tool 3 is slidably disposed on the lower mold core 11, and the sliding direction of the cutting tool 3 is parallel to the mating direction of the lower mold 1 and the upper mold 2.

[0018] Working principle: During the placement of the trim strip 9, the assembly surface of the trim strip 9 faces the lower mold 1, and the trim strip 9 is positioned by the positioning block 10 on the lower mold 1, so that the end of the trim strip 9 is located on the lower mold core 11, thereby placing the excess material to be removed above the cutter 3. Then, the machine tool drives the upper mold 2 to close with the lower mold 1, so that the pressure block 21 presses against the outer surface of the end of the trim strip 9. The pressure block 21 and the lower mold core 11 cooperate to clamp the end of the trim strip 9, and then the cutter 3 is driven to cut off the excess material at the end of the trim strip 9 from the assembly surface towards the outer surface, thereby preventing the outer surface of the trim strip 9 from collapsing and deforming.

[0019] It is worth noting that the cutting tool 3 cuts from bottom to top, that is, the cutting tool 3 moves from the mounting surface of the trim strip 9 towards the outer surface, so as to create a raised deformation at the punching position on the outer surface of the trim strip 9. Compared with the collapsed deformation, the raised part can be directly ground in the grinding and polishing process.

[0020] The movement of the cutting tool 3 can be achieved by using a drive mechanism (such as a pneumatic cylinder, electric cylinder, hydraulic cylinder, etc.) with a reciprocating movable end on the bottom surface of the lower mold 1. The movable end of the drive mechanism passes through the lower mold 1 and is connected to the cutting tool 3.

[0021] In some implementations, please refer to Figure 1 and Figure 4 As shown, the closing surface of the lower mold 1 is provided with a slider 12 that moves toward the tool 3. The slider 12 is provided with a first inclined surface 121 that abuts against the bottom of the tool 3. The slider 12 can lift the tool 3 using the first inclined surface 121, thereby realizing the punching operation of the tool 3 from bottom to top.

[0022] In some implementations, please refer to Figure 4 As shown, the bottom of the cutter 3 is provided with a second inclined surface 31 that matches the first inclined surface 121. The first inclined surface 121 and the second inclined surface 31 enable the slider 12 to lift the cutter 3 more smoothly.

[0023] In some implementations, please refer to Figure 1As shown, the above-mentioned trimming mold also includes a first connector 4 and a first spring 5. The first connector 4 passes through the lower mold 1 and is connected to the cutter 3. The elastic end of the first spring 5 abuts against the end of the first connector 4 away from the cutter 3. After the trimming 9 is completed, the elastic force generated by the first spring 5 drives the cutter 3 and the slider 12 to automatically reset.

[0024] It is worth noting that the first spring 5 can also be connected between the cutter 3 and the lower die 1.

[0025] In some implementations, please refer to Figure 1 and Figure 5 As shown, the lower mold 1 has a first limiting block 13 on its closing surface, and a gap 8 is left between the slider 12 and the first limiting block 13; the upper mold 2 has a push block 22 located above the gap 8, and the thickness of the push block 22 is greater than the width of the gap 8. During the mold closing process, the push block 22 is inserted into the gap 8 to force the width of the gap 8 to expand, that is, to push the slider 12 to move towards the tool 3.

[0026] In some implementations, please refer to Figure 5 As shown, the end of the slider 12 facing the upper mold 2 is provided with a third inclined surface 122 that is inclined toward the gap 8. The third inclined surface 122 contacts the push block 22 to guide the push block 22 into the gap 8.

[0027] In some implementations, please refer to Figure 5 As shown, the pusher block 22 is provided with a fourth inclined surface 221 that is adapted to the third inclined surface 122. The third inclined surface 122 and the fourth inclined surface 221 enable the pusher block 22 to be inserted into the gap 8 more smoothly.

[0028] In some implementations, please refer to Figure 5 As shown, the trimming mold for trimming trimming also includes a second connector 6 and a second spring 7. The second connector 6 passes through the first limiting block 13 and is connected to the slider 12. The elastic end of the second spring 7 abuts against the end of the second connector 6 away from the slider 12. After the trimming trim 9 is punched, the elastic force generated by the second spring 7 drives the slider 12 to automatically reset.

[0029] It is worth noting that the second spring 7 can also be connected between the slider 12 and the first limiting block 13.

[0030] In some implementations, please refer to Figure 2 and Figure 3 As shown, the mold closing surface of the lower mold 1 is provided with a second limiting block 14. During the mold closing process, the second limiting block 14 is used to limit the distance between the upper mold 2 and the lower mold 1, so as to prevent the relevant accessories on the upper mold 2 from overtraveling and damaging the appearance surface of the trim strip 9.

[0031] In some implementations, please refer to Figure 6 As shown, the lower die core 11 is provided with a guide groove 111, and the cutting tool 3 is slidably mounted on the guide groove 111. The guide groove 111 guides the movement direction of the cutting tool 3, thereby ensuring the punching quality of the trim strip 9 by the cutting tool 3.

[0032] Example 1 Please refer to Figures 1 to 5 As shown, a trimming mold for decorative strips includes a lower mold 1, an upper mold 2, and a cutting tool 3. The lower mold 1 has a lower mold core 11 on its mating surface; the upper mold 2 has a pressure block 21 adapted to the lower mold core 11; the cutting tool 3 is slidably disposed on the lower mold core 11, and the sliding direction of the cutting tool 3 is parallel to the mating direction of the lower mold 1 and the upper mold 2. The mating surface of the lower mold 1 has a slider 12 that moves toward the cutting tool 3, and the slider 12 has a first inclined surface 121 that abuts against the bottom of the cutting tool 3. The mating surface of the lower mold 1 has a first limiting block 13, and a gap 8 is left between the slider 12 and the first limiting block 13; the upper mold 2 has a push block 22 located above the gap 8, and the thickness of the push block 22 is greater than the width of the gap 8.

[0033] Working principle: During the placement of the trim strip 9, the assembly surface of the trim strip 9 faces the lower mold 1, and the trim strip 9 is positioned by the positioning block 10 on the lower mold 1, so that the end of the trim strip 9 is located on the lower mold core 11, thereby placing the excess material to be removed above the cutter 3. Then, the machine tool drives the upper mold 2 and the lower mold 1 to close, so that the pressure block 21 presses on the outer surface of the end of the trim strip 9. The pressure block 21 and the lower mold core 11 cooperate to clamp the end of the trim strip 9. At the same time, the push block 22 is inserted into the gap 8 to force the width of the gap 8 to expand, that is, to push the slider 12 to move towards the cutter 3. The slider 12, using the first inclined surface 121, can drive the cutter 3 to cut the excess material at the end of the trim strip 9 from the assembly surface of the trim strip 9 towards the outer surface, thereby preventing the outer surface of the trim strip 9 from collapsing and deforming.

[0034] Example 2 This embodiment further defines the reset structure of the tool 3 based on Embodiment 1, as follows: Please refer to Figure 4 Zhihe Figure 5 As shown, the first connecting piece 4 passes through the lower mold 1 and is connected to the cutter 3. The elastic end of the first spring 5 abuts against the end of the first connecting piece 4 away from the cutter 3. The second connecting piece 6 passes through the first limiting block 13 and is connected to the slider 12. The elastic end of the second spring 7 abuts against the end of the second connecting piece 6 away from the slider 12.

[0035] Working principle: During the mold opening process, the upper mold 2 drives the push block 22 out of the gap 8, so that the second connecting piece 6, under the elastic force of the second spring 7, pulls the slider 12 towards the first limit block 13, thereby resetting the slider 12 and freeing up the space required for the tool 3 to reset. At the same time, the first connecting piece 4, under the elastic force of the first spring 5, resets the tool 3. This achieves automatic reset, facilitating the next round of trim strip 9 processing.
