DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments: Example

[0030] See also Figure 1-8 A hole-punching device for an EPP foaming molding mold for automobiles comprises a processing table 1, a support frame 2 is slidably mounted on the processing table 1 through a lateral moving component, a motor I3 is fixed on the processing table 1, a lateral clamping component is driven and mounted on the motor I3, a pair of L-shaped brackets 13 for clamping the mold are mounted on the lateral clamping component, the L-shaped bracket 13 is longitudinally slidably mounted on the lateral clamping component, a motor II6 is fixed on the support frame 2, a rotating shaft 43 is coaxially fixed to the output shaft of the motor II6, a transmission sleeve 7 is slidably sleeved on the rotating shaft 43, a transmission bar 42 fixed to the rotating shaft 43 is slidably mounted inside the transmission sleeve 7, and the transmission sleeve A drill bit 8 is fixed to the lower end of the tube 7, a motor III9 is ​​fixed to the support frame 2, a reverse sliding assembly is driven and connected to the motor III9, a lifting frame I14 and a lifting frame II15 with opposite sliding directions are connected to the reverse sliding assembly, a transmission sleeve 7 is rotatably mounted on the lifting frame II15, a connecting frame 24 is mounted on the lifting frame I14 through an elastic connecting assembly, a guide assembly for guiding the connecting frame 24 is fixed to the support frame 2, a rotating sleeve 22 is rotatably mounted on the connecting frame 24, an absorption assembly is mounted on the rotating sleeve 22, a rotating frame 17 is fixed to the rotating sleeve 22, and each rotating frame 17 is mounted with a cleaning assembly.

[0031] When the device is used to perform hole-opening processing on the EPP foaming mold for automobiles, the mold is placed on two L-shaped brackets 13, and the two L-shaped brackets 13 support the mold. The two L-shaped brackets 13 are driven by means of the transverse clamping assembly, so that the two L-shaped brackets 13 move toward each other and clamp the mold. The motor II6 is set to drive the rotating shaft 43 to rotate, and the rotating shaft 43 drives the transmission sleeve 7 to rotate through the transmission bar 42, and the transmission sleeve 7 drives the drill bit 8 to rotate to perform hole-opening processing on the mold.

[0032] The reverse sliding assembly of the device includes a transmission gear 18 fixed coaxially with the output shaft of the motor III9, and the two sides of the transmission gear 18 are respectively meshed and connected with vertically arranged racks I19 and II34, and the racks I19 and II34 are respectively fixed on the lifting frame I14 and the lifting frame II15.

[0033] The motor III9 can drive the transmission gear 18 to rotate, and the transmission gear 18 drives the rack I19 and the rack II34 to move in opposite directions. When the rack II34 drives the lifting frame II15 to move vertically downward, the transmission sleeve 7 drives the drill bit 8 to move vertically downward to drill holes in the mold. In this process, the rack I19 drives the lifting frame I14 to move vertically upward, so that under the connection of the elastic connection component, the connecting frame 24 moves, and under the guidance of the guide component, it can achieve the hole opening position away from and offset from the mold, so as to avoid the connection frame 24 from interfering with the drill bit 8 when the drill bit 8 drills the mold.

[0034] The elastic connection assembly includes a guide rod 26 slidably mounted on the lifting frame I14, the guide rod 26 is fixed to the connecting frame 24, and a spring ring 27 sleeved on the guide rod 26 is fixedly connected between the connecting frame 24 and the lifting frame I14. The guide assembly includes a guide frame 10 fixed to the support frame 2, and the guide frame 10 is provided with a vertical groove I39, an inclined groove 40 and a vertical groove II41 with a smooth transition, and a slide bar 25 is fixed to the connecting frame 24, which is slidably matched with one of the vertical groove I39, the inclined groove 40 and the vertical groove II41.

[0035] Through the above arrangement, when the drill bit 8 moves upward after completing the die hole drilling, the connecting frame 24 moves downward, and the slide bar 25 slides and adapts with the vertical slot I39, the inclined slot 40 and the vertical slot II41 in sequence. At this time, the connecting frame 24 first moves vertically downward and then moves toward the die to the top of the hole slot. Finally, the connecting frame 24 drives the cleaning component to move downward and extend to the inside of the hole slot. At this time, the cleaning component realizes the rotation cleaning of the debris inside the hole slot, and absorbs the debris with the help of the absorption component, ensuring the cleanliness of the inside of the hole slot. The above process realizes the reverse movement of the drill bit 8 and the cleaning component, realizes the coherent operation of the die hole drilling and debris cleaning, and effectively improves the die hole drilling processing effect. Example

[0036] See also Figure 1-8 On the basis of Example 1, in addition, a motor IV11 is fixed on the connecting frame 24 of the device, a driving bevel gear 20 is coaxially fixed to the output shaft of the motor IV11, and a driven bevel gear 21 fixedly sleeved on the rotating sleeve 22 is meshedly connected to the driving bevel gear 20.

[0037] The motor IV11 drives the active bevel gear 20 to rotate, the active bevel gear 20 drives the driven bevel gear 21 meshing therewith to rotate, the driven bevel gear 21 drives the rotating sleeve 22 to rotate, the rotating sleeve 22 drives the rotating frame 17 to rotate, and the rotating frame 17 drives the cleaning component to rotate and clean the holes and grooves opened on the mold.

[0038] Specifically, the cleaning assembly of the device includes a bottom scraper 29 rotatably mounted on the rotating frame 17, a traction assembly is installed between the bottom scraper 29 and the rotating frame 17, a slide plate 33 is slidably mounted on the bottom scraper 29, a side scraper 32 is fixed on the slide plate 33, and a connecting spring 36 is fixed between the slide plate 33 and the bottom scraper 29. The traction assembly includes a vertical rod 44 vertically fixed on the rotating frame 17, a vertical slider 30 is slidably sleeved on the vertical rod 44, a push spring 31 is fixed between the vertical slider 30 and the rotating frame 17, and a connecting rod 35 is hinged between the vertical slider 30 and the bottom scraper 29.

[0039] At the same time, with the above-mentioned structure, the rotating frame 17 extends to the inside of the hole groove opened in the mold, and the bottom scraper 29 is arranged to abut against the bottom of the hole groove, so that the bottom scraper 29 rotates to a horizontal state relative to the rotating frame 17. At this time, the bottom scraper 29 abuts against the bottom of the hole groove, and at the same time, due to the rotation of the bottom scraper 29, the bottom scraper 29 pushes the vertical slider 30 to move upward relative to the vertical rod 44 through the connecting rod 35. At this time, the side scraper 32 rotates to a vertical state and abuts against the inner side wall of the hole groove. At this time, with the rotation of the rotating frame 17, the side scraper 32 and the bottom scraper 29 rotate simultaneously and fully rotate and clean the inside of the hole groove, and debris absorption is achieved with the help of the arranged absorption component.

[0040] Specifically, the absorption component includes a corrugated dust suction tube 23, which passes through the rotating sleeve 22 and extends to its lower part. An absorption cover 28 is fixed to the lower end of the corrugated dust suction tube 23. The end of the corrugated dust suction tube 23 away from the absorption cover 28 is connected to an external dust suction device. The absorption cover 28 moves down with the rotating frame 17 and enters into the hole groove to ensure that the debris can be fully absorbed.

[0041] The transverse clamping assembly of the device includes two coaxially fixed screws 16 with opposite thread rotation directions, each screw 16 is threadedly sleeved with a sliding frame 12 slidably mounted on the processing table 1, and an L-shaped bracket 13 is slidably mounted on the sliding frame 12. An L-shaped plate 37 and an L-shaped limit frame 38 are respectively fixed on the two L-shaped brackets 13, and the L-shaped plate 37 and the L-shaped limit frame 38 are slidably connected.

[0042] The motor I3 can drive the screw 16 to rotate, and the screw 16 drives the two sliding frames 12 to move toward each other, so that the L-shaped bracket 13 moves toward each other and clamps and limits the mold. After the above-mentioned clamping of the mold is completed, the L-shaped bracket 13 is driven to move by pulling the L-shaped plate 37 and the L-shaped limit frame 38, so that the mold can be longitudinally moved and adjusted relative to the sliding frame 12. In addition, the lateral movement component of the device includes a stud 5 threadedly installed on the processing table 1, one end of the stud 5 is rotatably installed on the support frame 2, and the other end of the stud 5 is fixed with a hand crank 4.

[0043] By shaking the crank handle 4, the stud 5 is rotated, and the stud 5 drives the support frame 2 to slide horizontally, so as to achieve horizontal adjustment of the drill bit 8. The horizontal position of the mold can be adjusted by the L-shaped plate 37 and the L-shaped limit frame 38, so as to achieve the adjustment effect of the position of the drill bit 8 and ensure accurate hole opening in the mold.

[0044] In summary, the present invention drives the reverse sliding assembly through the motor III9, so that the movement direction of the drill bit 8 is opposite to the movement direction of the cleaning assembly, so that when the drill bit 8 makes a hole in the mold, the cleaning assembly is offset from the hole groove under the action of the guide assembly, and when the drill bit 8 moves up and leaves the mold, the cleaning assembly moves and extends toward the hole groove and performs internal cleaning, so as to achieve the continuous action of mold hole making and hole groove cleaning, and greatly improve the mold processing efficiency. The cleaning assembly provided in the present invention can extend to the inside of the hole groove opened in the mold, and after the bottom scraper 29 pushes against the bottom of the hole groove, the side scraper 32 rotates toward the side wall of the hole groove to make contact, so that the cleaning assembly can automatically adjust the angles of the side scraper 32 and the bottom scraper 29 after entering the hole groove, so as to ensure the comprehensive and sufficient rotation cleaning of the hole groove opened on the mold, and the hole opening processing effect of the mold is significantly improved.
