[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] This utility model provides two technical solutions:

[0035] Figures 1-4 The first embodiment is shown: an air blowing cleaning structure for injection mold residue, comprising a base 1, a cleaning mechanism is provided at the top of the base 1 near the left side, and the cleaning mechanism comprises:

[0036] The retractable assembly 4 includes a second motor 41 and a carrying plate 42;

[0037] The axial rotation assembly 6 is disposed at the bottom of the retractable assembly 4 and connected to the air supply assembly 5. The axial rotation assembly 6 includes:

[0038] An L-shaped air pipe 62, the outer wall of which is rotatably provided with two bearing seats 61 fixedly connected to the bottom surface of the bearing plate 42, and a first driven gear 63 fixedly sleeved on the outer wall of the L-shaped air pipe 62 near the left side;

[0039] The third motor 64 is fixedly mounted on the bottom surface of the carrier plate 42. The output end of the third motor 64 is equipped with a first driving gear 65 meshing with the first driven gear 63. The third motor 64 can drive the first driving gear 65 to rotate, so that the first driven gear 63 and the L-shaped air pipe 62 rotate.

[0040] Cleaning agencies also include:

[0041] A lifting assembly 3 is provided on the top of the base 1;

[0042] The air supply assembly 5 is arranged on the top of the base 1;

[0043] The horizontal rotating assembly 7 is arranged on the outer wall of the L-shaped air tube 62 , and the angle of the horizontal rotating assembly 7 can be changed through the rotation of the L-shaped air tube 62 .

[0044] By starting the third motor 64, the first driving gear 65 is driven to rotate, thereby rotating the L-shaped air pipe 62, thereby changing the direction of the air nozzle 73 in the horizontal rotating assembly 7. When the air nozzle 73 is facing downward, the lower mold 21 can be blown clean, and when the air nozzle 73 is facing upward, the upper mold 23 can be blown clean.

[0045] Figures 1-4 The second embodiment is shown. The main difference from the first embodiment is that a mounting frame 11 is provided at the top of the base 1 near the rear side, and a mold mechanism 2 is provided at the top of the base 1 near the right side. The mold mechanism 2 includes:

[0046] The lower mold 21 is installed on the top of the base 1 near the right side;

[0047] The hydraulic cylinder 22 is installed on the top of the mounting frame 11. The telescopic end of the hydraulic cylinder 22 slides through the top of the mounting frame 11 and extends downward. The telescopic end of the hydraulic cylinder 22 is installed with an upper mold 23, and the upper mold 23 is placed above the lower mold 21.

[0048] In this embodiment, the lifting assembly 3 includes a stand 31 installed on the top of the base 1 near the left side, and a first motor 32 is installed on the top of the stand 31. The output end of the first motor 32 movably passes through the top of the stand 31 and extends inward. A screw rod 33 is installed on the output end of the first motor 32. The outer wall of the screw rod 33 is threadedly connected with a lifting seat 34. The left side of the lifting seat 34 is slidably set on the inner wall of the stand 31 through a slider and a slide rail.

[0049] Specifically, by starting the first motor 32, the screw rod 33 can be driven to rotate, so that the lifting seat 34 can move up and down along the slider and slide rail on the inner wall of the stand 31, thereby adjusting the overall height position of the cleaning mechanism so that it can accurately correspond to the position of the mold.

[0050] In this embodiment, the supporting plate 42 is arranged inside the lifting seat 34, and the second motor 41 is installed on the top of the lifting seat 34. The output shaft end of the second motor 41 movably passes through the top of the lifting seat 34 and extends inward, and is fixedly connected to the top surface of the supporting plate 42.

[0051] Specifically, the second motor 41 is started to drive the supporting plate 42 to rotate, thereby driving the axial rotation assembly 6 and the horizontal rotation assembly 7 to move out of or enter between the upper mold 23 and the lower mold 21 .

[0052] In this embodiment, the air supply assembly 5 includes an air pump 51 installed on the top of the base 1, and a hose 52 is installed at the output end of the air pump 51. The end of the hose 52 is fixedly connected to an air supply pipe 53. The outer wall of the air supply pipe 53 is fixedly sleeved with a fixed seat 54 fixedly connected to the bottom surface of the supporting plate 42. The end of the air supply pipe 53 is connected to one end of the L-shaped air pipe 62 through a rotary joint.

[0053] Specifically, after the air pump 51 is started, high-pressure gas with sufficient pressure can be generated. The gas is smoothly transmitted to the air supply pipe 53 through the hose 52, and finally enters the L-shaped air pipe 62 and subsequent connecting pipes 71, blowing pipes 72 and other components through the rotary joint, providing power for blowing cleaning.

[0054] In this embodiment, the horizontal rotation assembly 7 includes:

[0055] Connecting pipe 71, connecting pipe 71 is connected to the other end of L-shaped air pipe 62 through a rotary joint, the end of connecting pipe 71 is fixedly connected to blowing pipe 72, the outer wall of blowing pipe 72 is provided with multiple air nozzles 73, and the outer wall of connecting pipe 71 is fixedly sleeved with a second driven gear 74;

[0056] The support plate 75 is fixedly sleeved on the outer wall of the L-shaped air pipe 62 . A fourth motor 76 is installed on the outer surface of the support plate 75 . A second driving gear 77 meshing with the second driven gear 74 is installed on the output end of the fourth motor 76 .

[0057] Specifically, when the fourth motor 76 is started, it drives the second driving gear 77 to rotate. Since the second driving gear 77 is meshed and connected with the second driven gear 74, the connecting pipe 71 drives the blowing pipe 72 to rotate horizontally, and the mold can be blown and cleaned in all directions through multiple air nozzles 73.

[0058] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0059] During operation, first, the upper mold 23 is separated from the lower mold 21 by the hydraulic cylinder 22 according to the height position of the mold, and then the second motor 41 of the retractable assembly 4 is started to drive the supporting plate 42 to rotate, thereby driving the axial rotation assembly 6 and the horizontal rotation assembly 7 to enter between the upper mold 23 and the lower mold 21.

[0060] Afterwards, the first motor 32 in the lifting assembly 3 is started, and the first motor 32 drives the screw rod 33 to rotate, so that the lifting seat 34 moves up and down along the slider and slide rail on the inner wall of the stand 31, thereby adjusting the overall height position of the cleaning mechanism so that it can accurately correspond to the position of the mold.

[0061] Next, the air pump 51 of the air supply assembly 5 is started to generate high-pressure gas and transmit it to the L-shaped air pipe 62 through the hose 52 and the air supply pipe 53, and finally blows the mold from the air nozzle 73 through the connecting pipe 71 and the blowing pipe 72 to clean it.

[0062] When it is necessary to blow air to clean either the lower mold 21 or the upper mold 23, the third motor 64 is started to drive the first driving gear 65 to rotate, thereby rotating the L-shaped air pipe 62, thereby changing the direction of the air nozzle 73 in the horizontal rotating assembly 7. When the air nozzle 73 is facing downward, the lower mold 21 can be blown to clean, and when the air nozzle 73 is facing upward, the upper mold 23 can be blown to clean.

[0063] During the air blowing cleaning process, the fourth motor 76 is started to drive the second driving gear 77 to rotate. Under the action of meshing with the second driven gear 74, the connecting pipe 71 drives the air blowing pipe 72 to rotate horizontally, so that the air nozzle 73 can blow and clean the mold at different angles, thereby improving the cleaning effect.

[0064] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
