[0022] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part 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 creative work are within the scope of protection of the present invention.

[0023] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Refer to the attached Figure 1-Figure 5 , a waste material removing device for an injection molding machine in this embodiment comprises a workbench 1, and a slot is provided on the workbench 1, a fixed mold 2 is fixedly installed on the workbench 1, in this embodiment, the fixed mold 2 is fixedly installed on the left side of the slot, a movable mold 3 is arranged on the opposite side of the fixed mold 2, the movable mold 3 is arranged on the right side of the slot, an extrusion feeding device 4 is arranged on the outer side of the movable mold 3, the extrusion feeding device 4 comprises a bracket fixedly installed on the workbench 1, a material storage box is arranged on the top of the bracket, the material storage box and the movable mold 3 are connected by a pipeline, and a second cylinder is arranged between the movable mold 3 and the bracket, and the second cylinder is used to push the movable mold 3 to move to achieve the injection molding effect.

[0025] Refer to the attached Figure 1-Figure 5A mounting frame 5 with an inverted L-shaped structure is fixedly installed on the top of the workbench 1, and a first cylinder 6 is fixedly installed on the top of the mounting frame 5. The first cylinder 6 is arranged just above the notch, and a machine frame 7 is fixedly installed at the end of the piston rod of the first cylinder 6. A dual-axis motor 8 is fixedly installed in the machine frame 7. A plurality of heat dissipation grooves are provided on the machine frame 7. The heat dissipation grooves are arranged to facilitate the heat generated by the dual-axis motor 8 during operation to be dissipated. Brushes 9 are connected to the output ends of both sides of the dual-axis motor 8. When the dual-axis motor 8 is started during use, the rotation of the brushes 9 on both sides can be realized. After the injection molding is completed, waste materials will remain in the mold cavities of the movable mold 3 and the fixed mold 2. If it is not cleaned in time, it will affect the molding quality of the next plastic product processing. Therefore, after the injection molding is completed, the movable mold 3 and the fixed mold 2 are separated, and then the first cylinder 6 is started. The piston rod of the first cylinder 6 is extended to drive the machine frame 7, the dual-axis motor 8 and the brush 9 to move downward, so that the brush 9 moves to between the fixed mold 2 and the movable mold 3, and then the dual-axis motor 8 is started. The dual-axis motor 8 drives the brushes 9 on both sides to rotate to clean the mold cavity of the fixed mold 2 and the mold cavity of the movable mold 3. The dual-axis motor 8 and two brushes 9 are used to clean the mold cavity of the fixed mold 2 and the mold cavity of the movable mold 3 on both sides at the same time, and the working efficiency is high.

[0026] Refer to the attached Figure 1 , Figure 2 and Figure 5 A first protective plate 10 is fixedly mounted on the mounting frame 5, and the first protective plate 10 intercepts the waste splashed during the cleaning process from the rear side. A front protective assembly 11 is arranged on the workbench 1 on the opposite side of the first protective plate 10. The front protective assembly 11 is arranged on the front side of the fixed mold 2 and the movable mold 3. The front protective assembly 11 includes a mounting frame 1101 fixedly mounted on the workbench 1, and the top of the mounting frame 1101 is open. A screw 1102 is rotatably mounted in the mounting frame 1101, and a hand wheel is fixedly mounted on one end of the screw 1102. 1103, a second protective plate 1104 is threadedly connected to the screw rod 1102, and the bottom width of the second protective plate 1104 is equal to the width inside the installation frame 1101, thereby limiting the second protective plate 1104, so that the second protective plate 1104 can move laterally along the installation frame 1101 during the rotation of the screw rod 1102. When the second protective plate 1104 moves to a position corresponding to the front and rear of the first protective plate 10, the second protective plate 1104 intercepts the waste splashed during the cleaning process from the front side.

[0027] At the same time, the second protective plate 1104 is designed to be a movable structure, which is useful for operators to take out the injection-molded plastic products from the front side. By setting the first protective plate 10 and the second protective plate 1104, the waste splashed during the cleaning process can be effectively intercepted, which can prevent the splashed waste from accidentally injuring the workers and increase the work intensity of the workers to clean up the splashed waste.

[0028] Refer to the attached Figure 1-Figure 4 A waste collection mechanism 12 is provided under the workbench 1. The waste collection mechanism 12 includes a collection box 1201, and the bottom of the collection box 1201 is a conical structure. A collection frame 1206 is fixedly installed at the bottom of the workbench 1 and is connected to the notch. Plastic waste generated during the production process passes through the notch and falls into the collection box 1201. Two rotating rods 1202 are rotatably installed in parallel on the collection box 1201. A knife group 1203 is fixedly installed on the two rotating rods 1202. Gears 1204 are fixedly installed on the two rotating rods 1202, and the two gears 1204 are meshedly connected. A driving motor 1205 is provided on the outside of the collection box 1201. The output end of the driving motor 1205 is connected to one of the rotating rods 1202, and a motor frame is fixedly installed on the collection box 1201. The driving motor 1205 is fixedly installed on the motor frame. When in use, the driving motor 1205 is connected to an external power supply, and the driving motor 1205 is started. The driving motor 1205 can drive the rotating rod 1202 connected thereto to rotate. Under the meshing connection of the two gears 1204, the two rotating rods 1202 rotate at the same time, and the rotation directions of the two rotating rods 1202 are opposite. When waste falls into the collection box 1201, the knife groups 1203 fixedly installed on the two rotating rods 1202 will crush the waste.

[0029] Refer to the attached Figure 1 and Figure 3 A collection frame 1206 is slidably mounted on the collection box 1201, and the collection frame 1206 is arranged below the rotating rod 1202. A filter plate 1207 is fixedly mounted inside the collection frame 1206. The filter plate 1207 can intercept plastic waste with large particles after crushing. When the operator pulls the collection frame 1206 out of the collection box 1201, the intercepted waste can be collected and crushed again, while plastic waste with a size smaller than the filter holes on the filter plate 1207 will pass through the filter plate 1207 and be directly discharged from the collection box 1201, and will be uniformly recycled and reused by the staff. A handle is fixedly mounted on the outside of the collection frame 1206, which is convenient for the staff to insert the collection frame 1206 into the collection box 1201 or remove the collection frame 1206 from the collection box 1201.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
