Injection molding uses a mold to inject liquid into the mold. The injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise size. Injection molding is a processing method used in mass production of certain complex-shaped parts. Specifically, it refers to the high-pressure injection of heated and melted plastic into the mold cavity by an injection molding machine, and after cooling and solidification, a molded product is obtained.

The automatic chip removal device for thermosetting plastic injection molding production, by pulling the push plate to move to the left with the lockless button switch against the surface of the fixed module, presses the cold air machine to energize, the cold air machine starts to blow air into the bellows, and the wind enters the fixed module through the air duct and the air hole to blow and remove the chips, so as to realize automatic chip removal inside the fixed module, avoiding the problem that the traditional method requires manual use of an air gun to clean the internal residue of the injection mold before the mold can be used for production, and the labor intensity is high and the production efficiency is low.

In addition, the material chips on the mold group cannot be blown off, resulting in residues, and the fixed mold cannot be cleaned, which affects the cleaning efficiency and increases the burden on workers. Therefore, an automatic material chip removal device for thermosetting plastic injection molding production is proposed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-Figure 4 An automatic chip removal device for thermosetting plastic injection molding production includes a frame 1 and a mold group 11 arranged on the frame 1. A collection groove 12 is slidably installed on the outer surface of the frame 1. A cleaning device is arranged inside the frame 1. The cleaning device includes a scraper 43. The scraper 43 rotates to scrape off the residual chips on the mold group 11.

[0030] In order to drive the slider 22 to move on the slide rail 23, the cleaning device also includes a driving motor 2, which is fixedly installed on the upper surface of the frame 1. The output shaft of the driving motor 2 is fixedly installed with a threaded rod 21 through a coupling. The outer surface of the threaded rod 21 is threadedly connected with the slider 22. The upper surface of the frame 1 is fixedly installed with a slide rail 23. The outer surface of the slider 22 is slidably installed with the outer surface of the slide rail 23. The outer surface of the slider 22 is fixedly installed with a cylinder 24. One end of the threaded rod 21 is fixedly installed with the upper surface of the frame 1 through a bearing seat. The threaded rod 21 is driven by the driving motor 2 to rotate, driving the slider 22 to move on the slide rail 23, thereby driving the cylinder 24 to move. The cylinder 24 is started to extend and retract the piston rod, driving the support frame 3 to extend and retract, so that the mold group 11 can be cleaned without affecting the mold group 11.

[0031] In order to drive the support frame 3 to move, the support frame 3 is fixedly installed at one end of the piston rod of the cylinder 24, and a rotating motor 31 is fixedly installed inside the support frame 3. A rotating rod 32 is fixedly installed on the output shaft of the rotating motor 31, and a rotating frame 33 is fixedly installed on one end of the rotating rod 32. By installing the support frame 3, when the piston rod of the cylinder 24 is extended or retracted, the support frame 3 is driven to move, and the rotating motor 31 is driven to drive the rotating rod 32 to rotate, thereby driving the rotating frame 33 to rotate. The movement of the support frame 3 drives the rotating frame 33 to move together, so that the device does not affect the closing of the mold group 11.

[0032] In order to drive the rotating rod 4 to rotate, the rotating rod 4 is fixedly installed inside the rotating frame 33 through a bearing, and a rotating motor 41 is fixedly installed inside the rotating frame 33. The output shaft of the rotating motor 41 drives the rotating rod 4 to rotate through a bevel gear set. One end of the rotating rod 4 passes through the rotating frame 33 and a support rod 42 is fixedly installed thereon. A scraper 43 is fixedly installed at one end of the support rod 42. By starting the rotating motor 41 to drive the bevel gear set to rotate, the rotating rod 4 is driven to rotate, thereby driving the scraper 43 fixedly installed with the support rod 42 to rotate together, so as to perform all-round cleaning of the mold group 11 and improve the cleaning efficiency.

[0033] By setting up a cleaning device, the material chips on the mold group 11 can be cleaned. The threaded rod 21 is driven to rotate by the driving motor 2, which drives the slider 22 and the cylinder 24 on the slider 22 to move, thereby driving the support frame 3 to move. The rotating motor 31 in the support frame 3 drives the rotating rod 32 to rotate, and drives the rotating frame 33 fixed to the rotating rod 32 to rotate. The rotating motor 41 drives the rotating rod 4 on the rotating frame 33 to rotate, and drives the scraper 43 fixed on the support rod 42 to rotate. This solves the existing technical problems that when cleaning residues, some parts of the mold group 11 cannot be blown by the cold air fan, resulting in unclear cleaning of the material chips on the mold group 11, and the material chips on the mold group 11 cannot be blown off, resulting in residues, and the fixed mold cannot be cleaned, which affects the cleaning efficiency and increases the burden on workers.

[0034] In order to cool the chips on the mold set 11 , an air blowing device is provided inside the frame 1 . The air blowing device includes a nozzle 6 . The nozzle 6 draws cold air to cool the chips on the mold set 11 .

[0035] In order to drive the fixed frame 5 to rotate, the blowing device also includes a fixed frame 5, which is fixedly installed on the outer surface of the support rod 42. A cleaning motor 51 is fixedly installed inside the fixed frame 5, and a deflection rod 52 is fixedly installed on the output shaft of the cleaning motor 51. By installing the fixed frame 5 on the support rod 42, the fixed frame 5 is driven to rotate together when the support rod 42 rotates, and the deflection rod 52 is driven to deflect by starting the cleaning motor 51, thereby driving the nozzle 6 to deflect, so as to better blow and cool the mold group 11 and cool and separate the chips.

[0036] In order to deflect the nozzle 6, one end of the deflection rod 52 passes through the fixed frame 5 and is fixedly installed with one end of the nozzle 6. A dust cover 61 is fixedly installed on the outer surface of the nozzle 6. A deflection frame 62 is hinged on the outer surface of the nozzle 6 through a pin. A support frame 63 is hinged on the outer surface of the deflection frame 62 through a pin. The support frame 63 is fixedly installed on the outer surface of the fixed frame 5. By installing the dust cover 61, it is prevented that the material chips will block the nozzle 6 during the blowing process, thereby affecting the wind force and thus the cleaning efficiency. The nozzle 6 is hinged to the deflection frame 62 through a pin, so that the nozzle 6 is fixed without affecting its deflection. The support frame 63 is hinged to the deflection frame 62 through a pin, so that the deflection frame 62 is fixed without affecting its deflection. The support frame 63 is fixedly installed on the fixed frame 5. The rotation of the fixed frame 5 drives the support frame 63 to rotate, so that the material chips on the mold group 11 can be blown and cooled, so that the material chips are cooled and separated.

[0037] In order to convey airflow to the nozzle 6, an air pump 7 is fixedly installed on the upper surface of the support frame 3, an air inlet pipe 71 is fixedly installed at the air inlet end of the air pump 7, and an air outlet pipe 72 is fixedly installed at the air outlet end of the air pump 7. One end of the air outlet pipe 72 is fixedly connected to one end of the nozzle 6. The airflow in the air is sucked by the air pump 7, and the material chips on the mold group 11 are blown through the nozzle 6 so that they fall after cooling.

[0038] By setting up an air blowing device, the material chips on the mold group 11 are cooled, and the fixed frame 5 is fixed to the support rod 42. When the support rod 42 rotates, the fixed frame 5 is driven to rotate together. The cleaning motor 51 drives the deflection rod 52 to deflect, driving the nozzle 6 to deflect. The dust cover 61 prevents the nozzle 6 from being blocked and affecting the wind force. The support frame 63 is fixedly installed with the fixed frame 5. The rotation of the fixed frame 5 drives the support frame 63 to rotate, thereby driving the deflection frame 62 hinged to the nozzle 6 to rotate. This solves the existing technical problems that when cleaning residues, some parts of the mold group 11 cannot be blown by the cold air blower, resulting in unclear cleaning of the material chips on the mold group 11, and the material chips on the mold group 11 cannot be blown off, resulting in residues, and the fixed mold cannot be cleaned, affecting the cleaning efficiency and increasing the burden on workers.

[0039] Working principle: After the mold group 11 is separated by the electric push rod, the drive motor 2 is started to drive the threaded rod 21 to rotate, driving the cylinder 24 on the slider 22 to move, starting the cylinder 24 to extend and retract the piston rod, driving the support frame 3 to move, starting the rotating motor 31 to drive the rotating rod 32 to rotate, thereby driving the rotating frame 33 to rotate, starting the rotating motor 41 to drive the rotating rod 4 to rotate, thereby driving the scraper 43 on the support plate to rotate, the support rod 42 rotates and drives the fixed frame 5 to rotate together, starting the cleaning motor 51 to drive the deflection rod 52 to deflect, driving the nozzle 6 to deflect back and forth, and cooling the debris on the mold group 11, the fixed frame 5 rotates to drive the support frame 63 to rotate, and the support frame 63 drives the deflection frame 62 hinged thereto to rotate, thereby driving the nozzle 6 hinged to the deflection frame 62 to rotate, and the collecting trough 12 collects the fallen material chips.
