[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] A plastic mold with an airflow auxiliary cleaning device, such as Figures 1 to 7 As shown, it comprises a cleaning mechanism 1, the outer wall of the cleaning mechanism 1 is fixedly connected with an adjusting mechanism 2, the bottom end of the adjusting mechanism 2 is fixedly connected with a base 3, the top end of the base 3 is fixedly connected with multiple groups of guide rods 4, the outer wall of the multiple groups of guide rods 4 is fixedly sleeved with a lower template 5, and the outer wall of the multiple groups of guide rods 4 is slidably sleeved with an upper template 6 located above the guide rods 4;

[0030] The cleaning mechanism 1 includes an air intake hood 101, the side wall of the air intake hood 101 is rotatably connected to two groups of air outlet hoods 106, the outer wall of each group of air outlet hoods 106 is respectively connected to multiple groups of nozzles 107, the side wall of the air intake hood 101 is connected to two groups of rubber sleeves 105, the ends of the two groups of rubber sleeves 105 are respectively connected to one group of air outlet hoods 106, the inner wall of the air intake hood 101 is fixedly connected to multiple groups of fans 104, the side wall of the air intake hood 101 is slidably connected to a sliding frame 102, the inner wall of the sliding frame 102 is fixedly connected to a filter cotton 103, and the filter cotton 103 is in a wave shape. Wave-shaped, the top of the base 3 is fixedly connected with two groups of hydraulic rods 7, the tops of the two groups of hydraulic rods 7 are fixedly connected to the side walls of the upper template 6, the inner wall of the sliding frame 102 is slidably connected with two groups of ball heads 108, the ends of the two groups of ball heads 108 extend to the inner wall of the air intake hood 101, one end of the ball head 108 located inside the sliding frame 102 is fixedly connected with a first return spring 109, the end of the first return spring 109 is fixedly connected to the inner wall of the sliding frame 102, and the air intake hood 101 is provided with a groove matching the ball head 108 at the contact position with the ball head 108.

[0031] The fan 104 pushes the airflow through the filter cotton 103 and into the air inlet cover 101. In the process of air passing through the filter cotton 103, dust and other particles in the air are filtered out, and the wavy filter cotton 103 can provide a larger surface area, so that the air can pass through the filter cotton 103 more smoothly. Then the air passes through the rubber sleeve 105 and enters the air outlet cover 106, and finally is ejected through the nozzle 107, so that the airflow blows on the inner wall of the upper mold plate 6 and the lower mold plate 5. The upper mold plate 6 slides on the outer wall of the guide rod 4 driven by the hydraulic rod 7, so as to realize the mold closing and separation between the upper mold plate 6 and the lower mold plate 5. The airflow is continuously ejected from the nozzle 107, which can not only clean the upper mold plate 6 and the lower mold plate 5 after separation, but also cool the upper mold plate 6 and the lower mold plate 5, so that the product can be cooled and formed faster during the injection molding process. After a period of use, by pulling the sliding frame 1 02, so that the sliding frame 102 drives the filter cotton 103 and the ball head 108 to slide. At this time, the ball head 108 is blocked by the air intake cover 101, so that the ball head 108 slides into the sliding frame 102 and compresses the first return spring 109. After the ball head 108 slides out of the air intake cover 101, the first return spring 109 rebounds and pushes the ball head 108 to return to its original position. After the entire sliding frame 102 is pulled out from the air intake cover 101, the sliding frame 102 with the new filter cotton 103 is pushed into the air intake cover 101. During the pushing process, the ball head 108 is blocked by the air intake cover 101 and slides into the sliding frame 102. When the ball head 108 is aligned with the groove, the first return spring 109 pushes the ball head 108 to return to its original position, so that the ball head 108 slides into the groove. In the process of pulling out the sliding frame 102, the elastic force of the first return spring 109 needs to be overcome, so that the sliding frame 102 will not slide out of the air intake cover 101 without human pulling.

[0032] Please refer to Figure 2 , Figure 3 and Figure 7 The adjusting mechanism 2 includes a sliding seat 201, which is fixedly connected to the bottom end of the air inlet cover 101. The bottom end of the sliding seat 201 is slidingly sleeved with a guide plate 202, which is fixedly connected to the top of the base 3. The inner wall of the guide plate 202 is fixedly connected with multiple groups of spring sheets 203. The side wall of the sliding seat 201 is provided with two groups of limiting grooves that match the spring sheets 203. The two groups of air outlet covers 106 are respectively fixedly connected with a group of gears 204 at the connection with the air inlet cover 101. The two groups of gears 204 are meshed with each other. The inner wall of the air inlet cover 101 is slidably connected with a limiting tooth 205 extending to the outside of the air inlet cover 101. The end of the limiting tooth 205 is meshed with a group of gears 204. The side wall of the limiting tooth 205 is fixedly connected with a second return spring 206, and the end of the second return spring 206 is fixedly connected to the inner wall of the air inlet cover 101.

[0033] By pushing the limiting tooth 205, the second return spring 206 is compressed. At this time, the limiting tooth 205 is not in contact with the gear 204. Then the upper air outlet cover 106 is pushed to flip, so that the upper air outlet cover 106 drives the nozzle 107 to flip, thereby changing the injection angle of the airflow. In the process of flipping the upper air outlet cover 106, the upper gear 204 is driven to rotate, so that the upper gear 204 drives the lower gear 204 to rotate, thereby making the lower air outlet cover 106 flip, so that the two groups of air outlet covers 106 can be adjusted synchronously, and then the limiting tooth 205 is released, so that the second return spring 206 pushes the limiting tooth 205 to reset. At this time, the limiting tooth 205 is meshed with the upper gear 204, thereby blocking the upper gear 204 from rotating. Therefore, the lower gear 204 cannot rotate at this time, so that the angles of the two groups of air outlet covers 106 will not change. 6, so that the air outlet cover 106 drives the sliding seat 201 to move, so that the sliding seat 201 slides inside the guide plate 202. During the sliding process of the guide plate 202, the limiting groove pushes the spring sheet 203, causing the spring sheet 203 to deform. When the sliding seat 201 is not in contact with this group of spring sheets 203, the spring sheet 203 rebounds under the action of its own elastic force. When the sliding seat 201 contacts another group of spring sheets 203, the other group of spring sheets 203 is compressed. As the sliding seat 201 slides, when the limiting groove is aligned with the spring sheet 203, the spring sheet 203 rebounds and extends into the limiting groove, so that the sliding seat 201 is blocked by the spring sheet 203 during the sliding process, thereby preventing the sliding seat 201 from sliding inside the guide plate 202 without human push, so that the air flow angle can be adjusted when cleaning different molds, and the position of the air outlet cover 106 can be changed.

[0034] When in use, the fan 104 pushes the air flow through the filter cotton 103 and into the air intake hood 101. In the process of air passing through the filter cotton 103, dust and other particles in the air are filtered out, which prevents the air flow from driving these particles to hit the inside of the mold and prevents the inner wall of the mold from being scratched. In addition, the wavy filter cotton 103 can provide a larger surface area, so that the air can pass through the filter cotton 103 more smoothly. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
