The upper mold base 31 has a driving assembly (not shown in the figure) for driving the molding mold group to move toward the supporting mold group. When the automobile exhaust pipe manufacturing device is in operation, the driving assembly drives the molding mold group to move toward the supporting mold group to mold the raw material, and the raw material will be molded into a finished product after passing through a plurality of molding mold groups in sequence. The lower mold mechanism 2 and the upper mold mechanism 3 are prior art and will not be described in detail.

[0032] Reference Figure 3 and Figure 4 The drilling mechanism 4 includes a double-sided drilling component 41 and a single-sided drilling component 42 arranged on one side of the double-sided drilling component 41. The double-sided drilling component 41 is used to drill holes on both sides of the automobile exhaust pipe groove at the same time, and the single-sided drilling component 42 is used to drill holes on one side of the automobile exhaust pipe groove.

[0033] Reference Figure 4 , Figure 5 and Figure 6Specifically, the double-sided drilling assembly 41 includes a double-sided buckling structure 411, a first drilling structure 412 and a second drilling structure 413 arranged on the upper mold mechanism 3. The double-sided buckling structure 411 is used to buckle and fix the groove part of the automobile exhaust pipe. The double-sided buckling structure 411 includes a double-sided buckling block 4111, a connecting pressure block 4112 arranged on the double-sided buckling block 4111 and a buckling pressure block 4113 arranged on the connecting pressure block 4112. The buckling pressure block 4113 and the connecting pressure block 4112 are slidably connected to the upper mold base 31 and driven by the driving assembly, that is, under the drive of the driving assembly, the buckling pressure block 4113 will drive the connecting pressure block 4112 and the double-sided buckling block 4111 to continuously approach the groove part of the automobile exhaust pipe, and finally buckle in the groove part of the automobile exhaust pipe to fix and position it.

[0034] In order to adapt to the first drilling structure 412 and the second drilling structure 413, side holes are respectively opened on both sides of the double-sided buckle block 4111, and the first drilling structure 412 and the second drilling structure 413 are respectively arranged on both sides of the double-sided buckle structure 411, with the first drilling structure 412 facing one of the side holes and the second drilling structure 413 facing the other side hole. In addition, the connection pressing block 4112 is provided with clearance grooves on both sides corresponding to the first drilling structure 412 and the second drilling structure 413 to avoid interference with the first drilling structure 412 and the second drilling structure 413 during drilling.

[0035] The first drilling structure 412 includes a first guide slider 4121 disposed on the upper die mechanism 3 and a first drilling block 4122 slidably connected to the upper die mechanism 3, and the first drilling block 4122 is provided with a first drilling wedge 4123. The first guide slider 4121 is fixed to the upper die seat 31 for guiding the first drilling wedge 4123. The first guide slider 4121 is slidably connected to the upper die seat 31, and the upper die seat 31 is provided with a slide groove (not shown in the figure) for adapting the first guide slider 4121. The first drilling block 4122 is driven by the driving assembly to drive the first drilling wedge 4123 to move. The first guide slider 4121 has an inclined surface, which faces the side hole, and the first drilling wedge 4123 abuts against the inclined surface. When the driving assembly drives the first drilling block 4122, the first drilling block 4122 drives the first drilling wedge 4123 to move along the inclined surface to approach or move away from the side hole.

[0036] The first drilling wedge 4123 is equipped with a first drilling tool 4124. The first drilling tool 4124 can be installed on the first drilling wedge 4123 in a threaded connection to facilitate disassembly and model replacement. The first drilling tool 4124 faces the side hole, and the first drilling wedge 4123 keeps approaching the side hole. The first drilling tool 4124 will extend into the side hole to punch the groove of the automobile exhaust pipe. By setting an inclined surface on the first guide slider 4121 to guide the first drilling wedge 4123, the first drilling structure 412 can adapt to the process with high hole depth requirements.

[0037] The second drilling structure 413 is used to adapt to holes with high position accuracy requirements. The second drilling structure 413 includes a second guide slider 4131 provided on the upper die mechanism 3 and a second drilling block 4132 slidably connected to the upper die mechanism 3. The second drilling block 4132 is provided with a second drilling wedge 4133. The second guide slider 4131 is fixed to the upper die seat 31 to guide the second drilling wedge 4133. The second drilling block 4132 is slidably connected to the upper die seat 31 and driven by the driving assembly. The upper die seat 31 is provided with a slide groove for cooperating with the second drilling block 4132 to slide.

[0038] In this embodiment, the second guide slider 4131 has an adapting inclined surface 41311, and the second drilling wedge 4133 has an adapting groove for matching the adapting inclined surface 41311. The second drilling wedge 4133 abuts against the second guide slider 4131 through the adapting groove. At the same time, the adapting inclined surface 41311 has guide slide protrusions 41312 on both sides, and the second drilling wedge 4133 has guide slide hooks 41331 on both sides for matching the guide slide protrusions 41312. The guide slide hooks 41331 are buckled on the guide slide protrusions 41312 and are slidably connected with the guide slide protrusions 41312. The second drilling wedge 4133 is installed with a second drilling tool, and the second drilling wedge 4133 faces the side hole.

[0039] Driven by the driving assembly, the second drilling block 4132 drives the second drilling wedge 4133 to move, and the second drilling wedge 4133 moves along the adapting inclined surface 41311 of the second guide slider 4131, thereby driving the second drilling tool to extend from the side hole to punch the groove of the automobile exhaust pipe. Due to the provision of the guide slider 41312 and the guide slider hook holding block 41331 for limiting, the movement of the second drilling tool is more stable, and the error during the movement is smaller, so that it can adapt to the high-precision position requirements while meeting the hole depth.

[0040] Reference Figure 7Similar to the double-sided drilling assembly 41, the single-sided drilling assembly 42 includes a single-sided buckle structure 421 and a single-sided drilling structure 422. The single-sided buckle structure 421 has a side hole only on one side, and the single-sided buckle structure 421 is lifted or lowered by the driving assembly. The single-sided drilling structure 422 faces the single-sided side hole, and the structure and working principle of the single-sided drilling structure 422 are the same as those of the second drilling structure 413, that is, under the drive of the driving assembly, the single-sided drilling structure 422 will extend into the side hole of the single-sided buckle structure 421 to drill a hole.
