Description

Technical Field

[0001] The present application relates to the technical field of injection molding, and particularly relates to a material taking fixture, a blanking mechanism and an injection molding device to which the material taking fixture is applied. Background Art

[0002] The injection molding manufacturing process is to inject liquid rubber material into a mold. After the rubber material in the mold solidifies, an injection molded product can be obtained. Some injection molded products also need to remove excess waste after injection molding.

[0003] An ejection mechanism is usually used when an injection molded product is demolded. However, for some molds with complex structures, it is difficult to set up an ejection mechanism, and it is necessary to manually peel the injection molded product from the mold. Manual operation will cause the injection molded product to be damaged due to uneven force during the demolding process, and the manual operation efficiency is low. Summary of the Utility Model

[0004] In view of this, the purpose of the present application is to provide a material taking fixture, a blanking mechanism and an injection molding device to which the material taking fixture is applied, so as to improve the injection molding manufacturing quality and manufacturing efficiency of injection molded products.

[0005] In order to achieve the above purpose, the present application provides the following technical solutions:

[0006] A material taking fixture is used to take out an injection molded product to be demolded from a mold. The material taking fixture includes a positioning component, a clamping component and a driving component. The positioning component is used to position a first part of the injection molded product; the clamping component is used to clamp a second part of the injection molded product; the driving component is used to drive the clamping component to move relative to the positioning component. Wherein, there is a distance between the first part and the second part on the injection molded product.

[0007] In a possible implementation manner, the positioning component includes a positioning block, and the positioning block is used to abut against the first part of the injection molded product.

[0008] In a possible implementation manner, a clamping block is connected to the positioning block, and the clamping block is used to be clamped to a third part on the injection molded product. There is a distance between the third part on the injection molded product and the first part and the second part respectively.

[0009] In a possible implementation manner, the clamping component includes a first chuck, a second chuck and a clamping driving part. The clamping driving part is used to drive the first chuck and the second chuck to move closer to or away from each other, and the first chuck and the second chuck are used to clamp the second part of the injection molded product.

[0010] The present application also provides a material unloading mechanism for unloading the injection molded product to be demolded from the mold to a preset area, wherein the material unloading mechanism comprises a material unloading robot and the above-mentioned material picking fixture, wherein the material picking fixture is connected to the material unloading robot, and the material unloading robot is used to control the movement of the material picking fixture.

[0011] The present application also provides an injection molding device, including a molding machine, a placing mechanism and a feeding mechanism, wherein the molding machine has a mold; and the placing mechanism is used to place embedded parts in the mold.

[0012] In a possible implementation, the placement mechanism includes a placement manipulator and a placement jig, the placement jig is connected to the placement manipulator, the placement manipulator is used to control the movement of the placement jig, and the placement jig is used to pick up and place the embedded parts.

[0013] In a possible implementation, the placement jig includes a pneumatic suction nozzle, and the pneumatic suction nozzle is used to pick up and place the embedded parts.

[0014] In a possible implementation, the placement jig includes a visual detector, and the visual detector is used to detect the position of picking up and placing the embedded parts.

[0015] In a possible embodiment, the injection molding equipment also includes a cleaning mechanism, which is used to clean the injection molding waste in the mold. The cleaning mechanism includes a driving robot arm and a cleaning clamping assembly. The driving robot arm is connected to the cleaning clamping assembly, and the driving robot arm is used to control the movement of the cleaning clamping assembly. The cleaning clamping assembly is used to clamp and place the injection molding waste.

[0016] The material removal jig of the present application is provided with a positioning component, a clamping component and a driving component. After the positioning component presses and positions the first part of the injection molded product in the mold, the clamping component clamps the second part of the injection molded product, and then the clamping component is pulled by the driving component, so that the clamping component pulls the second part of the injection molded product. When the clamping component pulls the injection molded product, the injection molded product is not easy to move, so it is convenient for the clamping component to pull multiple parts of the injection molded product, so that the injection molded product can be gradually separated from the mold cavity. When the clamping component pulls the second part of the injection molded product, the injection molded product undergoes elastic deformation, so that the injection molded product is gradually peeled off from the mold. In addition, the injection molded product is subjected to uniform force during the demolding process, and the injection molded product that is tightly bonded to the mold cavity can be demolded with high quality, reducing the risk of damage to the injection molded product during material removal.

[0017] The material unloading mechanism of the present application utilizes the mutual cooperation between the material unloading manipulator and the material picking fixture to improve the material unloading efficiency and product quality of the injection molded products.

[0018] The injection molding equipment of the present application improves the automation degree of injection molding manufacturing of injection molded products by setting a molding machine, a placement mechanism and a blanking mechanism, thereby improving the production efficiency and product quality of injection molded products.

[0086] The following specific embodiments will further illustrate the present application in conjunction with the above drawings. Specific embodiments

[0087] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0088] In the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0089] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0090] Refer to the following Figures 1 to 15 , the specific implementation methods of this application are further described in detail.

[0091] Reference Figure 1 The injection molded product 100 involved in this embodiment is described by taking the annular reinforcing ring 101 as an example. The annular reinforcing ring 101 is usually the internal structure of the audio equipment, which plays the role of reinforcing the strength and buffering protection of the assembled components.

[0092] Reference Figure 1 The annular reinforcement ring 101 is annular and has a notch 102, so that the annular reinforcement ring 101 can be deformed to adjust its own diameter. A plurality of through holes 103 are provided on the circumferential side wall of the annular reinforcement ring 101, so as to minimize the impact on the sound propagation of the audio equipment. In order to facilitate the connection of various components, embedded parts 104 are embedded on the inner circumferential wall of the annular reinforcement ring 101, and the embedded parts 104 are, for example, connecting nuts 105. It should be understood that other embedded parts 104 can also be embedded in the annular reinforcement ring 101, so that the annular reinforcement ring 101 can be assembled with other components.

[0093] Generally, the annular reinforcement ring 101 needs to be molded by two injection moldings, and a double-shot mold is required for the injection molding. The rubber material of the first injection molding of the annular reinforcement ring 101 is PC material, which can ensure the strength of the annular reinforcement ring 101. The rubber material of the second injection molding is silicone, so that the annular reinforcement ring 101 has a buffer protection function.

[0094] The connecting nut 105 is made by implant injection molding, which is a molding technology that places a pre-prepared implant of a different material in a mold, injects rubber, and then tightly combines and solidifies the molten rubber with the implant to finally form an integrated product.

[0095] However, usually in the injection molding process of the annular reinforcing ring 101, it is necessary for workers to place the connecting nut 105 in the mold in advance. However, the structure of the two-shot mold for injecting the annular reinforcing ring 101 is complex, and the field of vision is limited when workers place the connecting nut 105, making it impossible to ensure sufficient precision and efficiency. In addition, due to insufficient space, the two-shot mold of the annular reinforcing ring 101 cannot be provided with an ejection mechanism. After the annular reinforcing ring 101 is formed by secondary injection molding, the annular reinforcing ring 101 is tightly adhered to the mold. Therefore, the product can only be slowly taken out of the mold manually, which greatly affects the quality of the injection molded product 100 and the injection molding manufacturing efficiency.

[0096] Refer to Figure 1 and Figure 2 In order to improve the quality of the injection molded product 100 and the injection molding manufacturing efficiency, this embodiment provides an injection molding device 1, which can be used for injection molding the annular reinforcing ring 101.

[0097] Refer to Figure 2 As shown in the figure, the injection molding device 1 includes a molding machine 2, a placement mechanism 3, a blanking mechanism 4, a cleaning mechanism 5, a carrier 6, a carrier table 7 and a product conveyor line 8. The molding machine 2 is located between the placement mechanism 3 and the blanking mechanism 4, the cleaning mechanism 5 is arranged above the molding machine 2, and the carrier 6, the carrier table 7 and the product conveyor line 8 are respectively arranged around the molding machine 2.

[0098] Refer to Figure 1 and Figure 2 As shown in the figure, the molding machine 2 has a mold 21, and the type of the mold 21 is a two-shot mold 21, so that the annular reinforcing ring 101 can be formed by secondary injection molding. In this embodiment, the molding machine 2 is a two-station operation, that is, there are two two-shot molds 21 arranged side by side in the molding machine 2 to improve production efficiency. The connecting nut 105 is placed on the carrier 6. When the placement mechanism 3 works, it picks up the connecting nut 105 on the carrier 6 and then places the connecting nut 105 in the mold 21. When the cleaning mechanism 5 works, it takes out the injection molding waste from the mold 21 and temporarily stores it on the carrier table 7, so as to achieve the effect of removing the injection molding waste after injection molding. The injection molding waste is also called the sprue. The product conveyor line 8 can be a preset area for the blanking mechanism 4 to blank the injection molded product 100. The blanking mechanism 4 is used to blank the annular reinforcing ring 101 to be demolded in the mold 21 onto the product conveyor line 8.

[0099] Therefore, the injection molding device 1 provided in this embodiment can automatically place the embedded part 104 in the mold 21, automatically inject, automatically demold and blank, and automatically remove the waste, greatly improving the manufacturing efficiency and manufacturing quality of the injection molded product 100.

[0100] Refer to Figure 3, the placing mechanism 3 includes a placing manipulator 31 and a placing fixture 32. The placing fixture 32 is connected to the placing manipulator 31, and the placing manipulator 31 is used to control the movement of the placing fixture 32. Specifically, for example, the placing manipulator 31 can control the placing fixture 32 to move or rotate so that the placing fixture 32 reaches the corresponding position or faces the corresponding angle.

[0101] Referring to Figure 3 and Figure 4 , the placing fixture 32 includes a pneumatic suction nozzle 321, a vision detector 322, and a mounting base 323. The mounting base 323 is connected to the placing manipulator 31, and both the pneumatic suction nozzle 321 and the vision detector 322 are mounted on the mounting base 323. The pneumatic suction nozzle 321 is used to pick up and place the connecting nut 105. The vision detector 322 is a CCD device, and the vision detector 322 is used to detect the picking and placing positions of the connecting nut 105, thereby improving the accuracy of placing the connecting nut 105.

[0102] Referring to Figure 4 and Figure 5 , in this embodiment, since the structure of the mold 21 is complex, in order to facilitate further control of the movement of the pneumatic suction nozzle 321, a pushing cylinder 324 is connected to the mounting base 323. The pushing cylinder 324 is connected to the pneumatic suction nozzle 321, and the pushing cylinder 324 is used to control the movement of the pneumatic suction nozzle 321 relative to the mounting base 323.

[0103] Referring to Figure 5 and Figure 6 , when the mounting base 323 moves close to the mold 21, in order to improve the stability of the movement of the mounting base 323, a guide pin 325 is connected to the mounting base 323, and a guide hole 211 corresponding to the guide pin 325 is provided in the mold 21. When the placing manipulator 31 controls the mounting base 323 to move in the mold 21, the guide pin 325 is inserted into the guide hole 211, thereby improving the stability of the movement of the mounting base 323. In order to accurately position the mounting base 323, a limiting block 326 is connected to the mounting base 323. When the mounting base 323 moves to the specified position, the limiting block 326 abuts against the mold 21.

[0104] When the placing mechanism 3 places the connecting nut 105, first, the placing manipulator 31 controls the movement of the connecting seat 424 to move the connecting seat 424 to a position close to the carrier 6, and then the pneumatic suction nozzle 321 picks up the connecting nut 105 by suction. Then, the placing manipulator 31 controls the connecting seat 424 to move towards the mold 21. When the guide pin 325 is inserted into the guide hole 211 and the limiting block 326 abuts against the mold 21, the placing manipulator 31 keeps the connecting seat 424 stationary. Then, the pushing cylinder 324 drives the pneumatic suction nozzle 321 to move. When the pneumatic suction nozzle 321 moves to the designated position in the mold 21, the pneumatic suction nozzle 321 releases the suction force, so that the connecting nut 105 is placed at the corresponding position in the mold 21. Subsequently, the pushing cylinder 324 drives the pneumatic suction nozzle 321 to move away from the connecting nut 105 to reset. Then, the placing manipulator 31 controls the connecting seat 424 to move out of the mold 21, and the placement of the connecting nut 105 is completed.

[0105] Referring to Figure 7 , the blanking mechanism 4 includes a blanking manipulator 41 and a material taking fixture 42. The material taking fixture 42 is connected to the blanking manipulator 41, and the blanking manipulator 41 is used to control the movement of the material taking fixture 42. Specifically, for example, the blanking manipulator 41 can control the material taking fixture 42 to move or rotate so that the material taking fixture 42 reaches the corresponding position or faces the corresponding angle.

[0106] Referring to Figure 8 and Figure 9 , the material taking fixture 42 is used to take out the annular reinforcing ring 101 to be demolded in the mold 21. The material taking fixture 42 includes a positioning component 421, a clamping component 422, a driving component 423, and a connecting seat 424. The positioning component 421, the clamping component 422, and the driving component 423 are all arranged on the connecting seat 424, and the connecting seat 424 is used to be connected to the blanking manipulator 41 (referring to Figure 7 ).

[0107] It should be noted that the connecting seat 424 can be in other different structural forms. For example, in some other embodiments, the connecting seat 424 can be directly discarded, and the positioning component 421, the clamping component 422, and the driving component 423 can be directly installed on the blanking manipulator 41.

[0108] Referring to Figure 9 and Figure 10 , the positioning component 421 is used to position the first part 106 of the injection molded product 100, the clamping component 422 is used to clamp the second part 107 of the injection molded product 100, and the driving component 423 is used to drive the clamping component 422 to move relative to the positioning component 421. Among them, there is a distance between the first part 106 and the second part 107 on the injection molded product 100. That is to say, the first part 106 and the second part 107 on the injection molded product 100 are two different parts.

[0109] It should be noted that the first part 106 and the second part 107 can be adjusted according to the movement change of the material taking fixture 42. That is, the part of the injection molded product 100 positioned by the positioning component 421 is the first part 106. When the part of the injection molded product 100 positioned by the positioning component 421 changes, that is, the first part 106 changes. The part of the injection molded product 100 clamped by the clamping component 422 is the second part 107. When the part of the injection molded product 100 clamped by the clamping component 422 changes, that is, the second part 107 changes.

[0110] Refer to Figure 9 and Figure 10 , the positioning component 421 includes a positioning block 4211. The positioning block 4211 is fixed on the connecting seat 424. The positioning block 4211 has a pressing surface 4212, and the pressing surface 4212 is used to press against the first part 106 of the injection molded product 100. The pressing surface 4212 is an arc surface adapted to the inner circumferential wall of the annular reinforcing ring 101, so as to improve the pressing effect of the positioning block 4211 on the annular reinforcing ring 101.

[0111] Refer to Figure 9 and Figure 10 , an extension rod 4213 is connected to the positioning block 4211. The extension rod 4213 is used to be inserted into the through hole 103 of the annular reinforcing ring 101. A clamping block 4214 is connected to the end of the extension rod 4213 away from the positioning block 4211. The clamping block 4214 protrudes from the side of the extension rod 4213 close to the pressing surface 4212. When the material taking fixture 42 works, the clamping block 4214 is used to press against the inner wall of the through hole 103 to realize the clamping connection between the clamping block 4214 and the annular reinforcing ring 101.

[0112] Refer to Figure 9 and Figure 10 , the positioning component 421 is also used to clamp the third part 108 of the injection molded product 100. The position where the clamping block 4214 clamps the annular reinforcing ring 101 is the third part 108. When the clamping block 4214 moves with the positioning block 4211, it can play a peeling role on the third part 108 of the annular reinforcing ring 101. There is a distance between the third part 108 on the injection molded product 100 and the first part 106 and the second part 107 respectively. That is, the first part 106, the second part 107 and the third part 108 on the injection molded product 100 are three different parts.

[0113] Refer to Figure 8 , Figure 9 and Figure 10, to facilitate the positioning block 4211 to penetrate deep into the injection cavity of the mold 21, the positioning assembly 421 further includes a positioning extension rod 4215. One end of the positioning extension rod 4215 is fixedly connected to the connecting seat 424 by screws, and the other end of the positioning extension rod 4215 is fixedly connected to the positioning block 4211. To improve the stability of the positioning block 4211, the positioning extension rod 4215, the positioning block 4211, the extension rod 4213, and the clamping block 4214 are of an integrally formed structure.

[0114] Referring to Figure 9 and Figure 10 , the driving assembly 423 is a slide cylinder 4231. The clamping assembly 422 is connected to the slide cylinder 4231, and the slide cylinder 4231 is used to drive the clamping assembly 422 to move relative to the positioning assembly 421. The clamping assembly 422 includes a first chuck 4221, a second chuck 4222, and a clamping driving part 4223. The clamping driving part 4223 is used to drive the first chuck 4221 and the second chuck 4222 to move closer to or away from each other. The first chuck 4221 and the second chuck 4222 are used to clamp the second part 107 of the injection product 100. Specifically, the first chuck 4221 and the second chuck 4222 can be inserted into the through holes 103 formed in the circumferential wall of the annular reinforcing ring 101, so as to clamp the annular reinforcing ring 101 by using the first chuck 4221 and the second chuck 4222. The clamping driving part 4223 is a pneumatic finger 4224. The pneumatic finger 4224 is connected to the slide cylinder 4231, so that the slide cylinder 4231 drives the pneumatic finger 4224 to move on the connecting seat 424. The first chuck 4221 and the second chuck 4222 are connected to the pneumatic finger 4224, and the pneumatic finger 4224 is used to drive the first chuck 4221 and the second chuck 4222 to move closer to or away from each other.

[0115] Referring to Figure 9 and Figure 10In order to facilitate the first clamp 4221 and the second clamp 4222 to penetrate into the injection molding chamber of the mold 21, the clamping assembly 422 also includes a first extension rod 4225 and a second extension rod 4226. One end of the first extension rod 4225 is fixedly connected to the connecting seat 424, and the other end of the first extension rod 4225 is connected to the first clamp 4221, and the direction of the first clamp 4221 is perpendicular to the first extension rod 4225. One end of the second extension rod 4226 is fixedly connected to the connecting seat 424, and the other end of the second extension rod 4226 is connected to the second clamp 4222, and the direction of the second clamp 4222 is perpendicular to the second extension rod 4226. In order to improve the stability of the first clamp 4221 and the second clamp 4222, the first clamp 4221 and the first extension rod 4225 are integrally formed, and the second clamp 4222 and the second extension rod 4226 are integrally formed. The first extension rod 4225 and the second extension rod 4226 are arranged in parallel and are both fixed to the pneumatic finger 4224 by screws.

[0116] Reference Figure 9 and Figure 10 In order to improve the clamping effect of the first clamp 4221 and the second clamp 4222 on the annular reinforcement ring 101, two first clamps 4221 are arranged along the length direction of the first extension rod 4213, and two second clamps 4222 are arranged along the length direction of the second extension rod 4213.

[0117] When performing the unloading operation, the material taking fixture 42 needs to undergo Figures 11 to 13 When unloading, first use the unloading robot 41 to drive the connecting seat 424 to move toward the mold 21, and the connecting seat 424 drives the positioning component 421, the driving component 423 and the clamping component 422 to move, so that the positioning block 4211, the first clamp 4221 and the second clamp 4222 penetrate into the interior of the annular reinforcement ring 101. At this time, the material removal fixture 42 is in the first state, and the positioning block 4211, the first clamp 4221 and the second clamp 4222 do not contact the inner wall of the annular reinforcement ring 101. The first state is as follows: Figure 11 shown.

[0118] Then the unloading robot 41 drives the connecting seat 424 to move, and the connecting seat 424 drives the positioning block 4211 to move, so that the pressing surface 4212 of the positioning block 4211 presses against the inner wall of the annular reinforcement ring 101, and at the same time, the clamping block 4214 clamps and presses against the inner wall of the through hole 103 of the annular reinforcement ring 101. In this way, the first part 106 of the annular reinforcement ring 101 is pressed against and positioned, so as to avoid the annular reinforcement ring 101 from moving when the clamping assembly 422 is working. At this time, the material picking fixture 42 is in the second state, and the second state is as follows: Figure 12 shown.

[0119] Then, the slide table cylinder 4231 drives the pneumatic finger 4224 to move towards the inner wall of the annular reinforcing ring 101, so that both the first chuck 4221 and the second chuck 4222 are inserted into the through hole 103 of the annular reinforcing ring 101, and the first chuck 4221 and the second chuck 4222 are respectively inserted into different through holes 103. At this time, the material taking fixture 42 is in the third state, and the third state is as shown in Figure 13 shown.

[0120] Next, the pneumatic finger 4224 drives the first extension rod 4225 and the second extension rod 4226 to move closer to each other, thereby driving the first chuck 4221 and the second chuck 4222 to move closer to each other, so that the first chuck 4221 and the second chuck 4222 clamp the second part 107 of the annular reinforcing ring 101. Subsequently, the slide table cylinder 4231 drives the pneumatic finger 4224 to reset towards the center of the annular reinforcing ring 101, so that the first chuck 4221 and the second chuck 4222 pull the second part 107, enabling the second part 107 of the annular reinforcing ring 101 being pulled to be peeled off from the inner cavity of the mold 21. Subsequently, the blanking manipulator 41 controls the movement of the connecting seat 424, so that the positioning block 4211 moves towards the center of the annular reinforcing ring 101, and the positioning block 4211 drives the clamping block 4214 to move, so that the clamping block 4214 generates a pulling force on the third part 108 of the annular reinforcing ring 101. Thus, with the cooperation of the clamping block 4214, the first chuck 4221, and the second chuck 4222, multiple parts of the annular reinforcing ring 101 are pulled towards the center of the annular reinforcing ring 101, which can reduce the adhesion degree between multiple parts of the annular reinforcing ring 101 and the inner cavity of the mold 21, and further facilitate the overall detachment of the annular reinforcing ring 101 from the mold 21.

[0121] It should be understood that the positions of the clamping block 4214, the first chuck 4221, and the second chuck 4222 can also be adjusted multiple times to pull more parts of the annular reinforcing ring 101 and reduce the adhesion degree between the overall annular reinforcing ring 101 and the inner cavity of the mold 21, so that the annular reinforcing ring 101 can be more easily detached from the mold 21. Since the annular reinforcing ring 101 has a notch 102, it can deform to change its own diameter. According to the deformable characteristic of the annular reinforcing ring 101, different parts of the annular reinforcing ring 101 formed by injection molding in the mold 21 are positioned and pulled through the cooperation of the clamping block 4214, the first chuck 4221, and the second chuck 4222 to achieve better demolding quality.

[0122] Finally, under the clamping of the first chuck 4221 and the second chuck 4222 on the annular reinforcing ring 101, the blanking manipulator 41 controls the movement of the connecting seat 424, so that the connecting seat 424 drives the first chuck 4221 and the second chuck 4222 to move out of the inner cavity of the mold 21, thereby taking out the annular reinforcing ring 101 from the mold 21.

[0123] Reference Figure 14 , the cleaning mechanism 5 includes a driving robotic arm 51 and a cleaning clamping assembly 52. The driving robotic arm 51 is a three-coordinate robotic arm, and the cleaning clamping assembly 52 is connected to the driving robotic arm 51. The driving robotic arm 51 is used to control the movement of the cleaning clamping assembly 52. For example, the driving robotic arm 51 can control the cleaning clamping assembly 52 to move horizontally and vertically. In order to raise the height of the driving robotic arm 51 so that the cleaning clamping assembly 52 can move upward out of the mold 21, a support frame 53 is connected to the top of the molding machine 2 (reference Figure 2 ), and the driving robotic arm 51 is connected to the support frame 53.

[0124] Reference Figure 14 and Figure 15 , the cleaning clamping assembly 52 includes a lifting plate 521 and a jaw cylinder 523. The lifting plate 521 is connected to the three-coordinate robotic arm, and the jaw cylinder 523 is connected to the lifting plate 521. A plurality of avoidance openings 522 for avoiding the components in the mold 21 are formed in the lifting plate 521, so that when the lifting plate 521 penetrates into the mold 21 (reference Figure 2 ), the collision between the lifting plate 521 and the mold 21 can be avoided. The jaw cylinder 523 is used to clamp the injection molding waste.

[0125] After the injection-molded annular reinforcing ring 101 is taken out of the mold 21, during the cleaning operation, the driving robotic arm 51 is used to drive the cleaning clamping assembly 52 to penetrate into the mold 21, then the jaw cylinder 523 is used to clamp the injection molding waste, and then the driving robotic arm 51 drives the jaw cylinder 523 to move to the loading platform 7, and the jaw cylinder 523 releases the injection molding waste, that is, the cleaning operation of the injection molding waste is completed.
