DETAILED DESCRIPTION

[0043] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant accompanying drawings. Preferred embodiments of the present invention are given in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. It should be noted that when an element is referred to as "fixed to" another element, it can be directly on another element or there can also be a centered element. When an element is considered to be "connected" to another element, it can be directly connected to another element or there may be a centered element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes.

[0044] like Figure 1-16 As shown, a fuel tank cap injection molding device described in this embodiment includes an injection molding mechanism 15, a cooling machine 14 for cooling a product 12, a rotating mechanism 16 for flipping the orientation of the product 12, a sprue folding mechanism 17 for removing sprue residue 315 of the product 12, a grinding mechanism 18 for grinding the product 12, and a conveying mechanism 13 for moving the product 12 in the injection molding mechanism 15 to the cooling machine 14, the rotating mechanism 16, the sprue folding mechanism 17 and the grinding mechanism 18 in sequence; the cooling machine 14 is provided with a plurality of cooling carriers 11 for placing the product 12; the injection molding mechanism 15, the rotating mechanism 16 and the sprue folding mechanism 17 are all arranged on the side of the cooling machine 14; the grinding mechanism 18 is arranged on the side of the sprue folding mechanism 17.

[0045] Specifically, the conveying mechanism 13 can be any common robot arm on the market, and its structure is not limited.

[0046] Since the product 12 has a high temperature after being injection molded by the injection molding mechanism 15, the conveying mechanism 13 needs to place the product 12 on the cooling machine 14 first, and then carry out subsequent processing when it is cooled to a suitable temperature; in the subsequent processing steps, it is often necessary to process different surfaces of the product 12 separately. This requires turning the product 12 so that its orientation can be suitable for the processing at the next station. By setting the rotating mechanism 16, it can be ensured that the orientation of the product 12 can meet the processing requirements of the next station; in order to increase the production speed, usually one injection molding process will produce two semi-finished fuel tank caps, so there will be a nozzle residue 315 connected between the two fuel tank caps coming out of the injection molding process, so it is necessary to disconnect the nozzle residue 315 from the two fuel tank caps before entering the next process. By setting the nozzle folding mechanism 17, the nozzle residue 315 can be automatically folded to disconnect the two connected products 12 from the nozzle residue 315; after the nozzle residue 315 is disconnected, the grinding process can be carried out, and the corners of the product 12 can be polished by setting the grinding mechanism 18. The present invention can realize automatic folding of water outlets and automatic grinding of corners, has low labor cost and low operation intensity, effectively reduces potential safety hazards during operation of workers, has a high degree of automation and high work efficiency.

[0047] like Figure 3-7 As shown, in the present embodiment, a fuel tank cap injection molding device, the grinding mechanism 18 includes a grinding frame 110, a grinding carrier 111 for placing a product 12, a rotating device 120 for rotating the grinding carrier 111, an anti-slip limit device for preventing the product 12 from escaping from the grinding carrier 111 when rotating, and a cutter head device 130 for grinding the product 12; the rotating device 120 includes a rotating driving member 121 and a fixing seat 122 mounted on the grinding frame 110; the grinding carrier 111 is rotatably connected to the fixing seat 122; the output end of the rotating driving member 121 is connected to the grinding carrier 111; the rotating driving member 121 Used to make the grinding carrier 111 rotate in the fixed seat 122; the rotating drive member 121 is connected to the grinding machine frame 110; the cutter head device 130 includes a cutter head 131 and a grinding power component for controlling the distance between the cutter head 131 and the product 12 on the grinding carrier 111; the cutter head 131 is installed on the grinding machine frame 110 through the grinding power component; the anti-slip limit device includes an anti-slip seat 141, a pressure block 142 for limiting the product 12 on the grinding carrier 111, and an anti-slip installation component for detachably connecting the anti-slip seat 141 to the fixed seat 122; the pressure block 142 is rotatably connected to the anti-slip seat 141.

[0048] Specifically, the shape of the grinding carrier 111 matches the product 12; in order to adapt to products 12 of various shapes, the grinding carrier 111 and the grinding carrier seat 123 can be detachably connected to facilitate the replacement of different models of grinding carriers 111; the grinding carrier seat 123 and the fixed seat 122 can be rotatably connected through a bearing; before starting the grinding process, the product 12 must first be placed on the grinding carrier 111, and then the anti-slip seat 141 is installed on the fixed seat 122 to ensure that the pressure block 142 can press the product 12 tightly on the grinding carrier 111. Then the grinding process can be started. During grinding, the output end of the rotating driving member 121 drives the grinding carrier 111 to rotate, thereby driving the product 12 on the grinding carrier 111 to rotate. Because the pressing block 142 is rotatably connected to the anti-drop seat 141, when the product 12 rotates, the pressing block 142 can prevent the product 12 from falling off and does not hinder the rotation of the product 12. After the rotation of the product 12 is stable, the grinding power component drives the cutter head 131 to approach the product 12 until the cutter head 131 touches the product 12. Since the product 12 keeps rotating, the edge of the product 12 can be ground without the cutter head 131 moving. After the grinding is completed, the grinding power component then retracts the cutter head 131 to the initial position, waiting for the next product 12 to be ground. After the product 12 is polished, the rotating driving member 121 stops rotating the product 12, and then the anti-slip seat 141 is separated from the fixing seat 122 to release the restriction on the product 12, and the next product 12 to be polished is replaced, and the above steps are repeated.

[0049] like Figure 3-4 As shown, the fuel tank cap injection molding equipment described in this embodiment, the polishing power component includes a polishing fixed frame 132 installed on the polishing machine frame 110, a polishing guide rail 133 installed on the polishing fixed frame 132, a polishing slider 134 slidably connected to the polishing guide rail 133, and a polishing drive 135 for making the polishing slider 134 slide along the polishing guide rail 133; the cutter head 131 is installed on the polishing slider 134; the polishing drive 135 is installed on the polishing fixed frame 132; the cutter head 131 and the polishing slider 134 are detachably connected.

[0050] Specifically, the grinding drive 135 can be a cylinder; when the cutter head 131 needs to be pushed closer to the product 12 or farther away from the product 12, the grinding function can be realized by only making the output end of the grinding drive 135 push the grinding slider 134 to move forward or backward accordingly. Since the cutter head 131 and the grinding slider 134 are detachably connected, the cutter head 131 may become less sharp due to wear in the case of long-term operation. Therefore, the above arrangement allows the cutter head 131 to be easily replaced.

[0051] like Figure 3-7As shown, in the fuel tank cap injection molding equipment described in this embodiment, the pressing block 142 is arranged at the bottom of the anti-slip seat 141; the anti-slip installation component includes a supporting foot 143, an anti-slip plate 144, an anti-slip guide column 145 and an anti-slip lifting drive member 147; the anti-slip plate 144 is located above the fixed seat 122; the anti-slip plate 144 is installed on the grinding machine frame 110 through the supporting foot 143; the bottom of the anti-slip guide column 145 passes through the anti-slip plate 144; and the anti-slip plate 144 is located above the fixed seat 122. The guide post 145 is slidably connected to the anti-slip plate 144; the anti-slip seat 141 is connected to the bottom of the anti-slip guide post 145; the anti-slip lifting drive member 147 is installed on the top surface of the anti-slip plate 144; the output end of the anti-slip lifting drive member 147 passes through the anti-slip plate 144 and is connected to the anti-slip seat 141; at least one positioning hole 148 is provided on the fixed seat 122; the bottom of the anti-slip seat 141 is provided with a positioning protrusion 149 corresponding to the positioning hole 148;

[0052] When the grinding process is performed, the pressing block 142 needs to be pressed against the product 12 to prevent it from falling off during the grinding process. The anti-slip lifting drive 147 can be a cylinder. Specifically, before the grinding process begins, the output end of the anti-slip lifting drive 147 extends out to push the anti-slip anti-slip seat 141 down. At this time, the anti-slip guide column 145 simultaneously descends, so that the pressing block 142 at the bottom of the anti-slip seat 141 falls stably. The pressing block 142 continues to fall until the positioning protrusion 149 completely falls into the positioning hole 148 on the fixed seat 122, so that the fixed seat 122 and the anti-slip seat 141 are fixedly connected. At this time, the pressing block 142 will also press against the top of the product 12, and then the grinding process can be started. After the grinding is completed, it is only necessary to retract the output end of the anti-slip lifting drive 147 to drive the positioning protrusion 149 on the anti-slip seat 141 to leave the fixed seat 122.

[0053] like Figure 3-7 As shown, in the fuel tank cap injection molding equipment described in this embodiment, the number of the anti-slip guide columns 145 is four; the four anti-slip guide columns 145 are slidably connected to the anti-slip plate 144 through linear bearings 146 respectively.

[0054] Specifically, by providing a plurality of anti-slip guide posts 145 and linear bearings 146 , the anti-slip seat 141 can be made more stable during the descent process.

[0055] like Figure 3 and 7As shown, in the fuel tank cap injection molding equipment described in this embodiment, the grinding carrier 111 is rotatably connected to the fixed seat 122 through a rotating component; the rotating component includes a grinding carrier seat 123 and a rotating bearing 124; the grinding carrier seat 123 is penetrated in the fixed seat 122; the grinding carrier 111 is detachably connected to one end of the grinding carrier seat 123; the rotating driving member 121 is connected to the other end of the grinding carrier seat 123; the rotating bearing 124 is arranged between the grinding carrier seat 123 and the fixed seat 122; the grinding carrier seat 123 and the grinding carrier 111 are connected by screws;

[0056] Specifically, by adding a polishing carrier seat 123 and making the polishing carrier 111 detachably connected to the polishing carrier seat 123, different polishing carriers 111 can be replaced according to different products 12, and the versatility is stronger. By setting a rotating bearing 124, it is helpful to reduce the friction between the polishing carrier seat 123 and the fixed seat 122, so that the rotation is more stable. The use of screws has strong versatility and low cost.

[0057] like Figure 3-7 As shown, in the fuel tank cap injection molding equipment described in this embodiment, the number of the grinding carriers 111, the number of the anti-slip limit devices and the number of the cutter head devices 130 are all two sets; the number of the fixed seats 122, the number of the grinding carrier seats 123 and the number of the rotating bearings 124 are all two; the rotating driving member 121 drives the two grinding carrier seats 123 to rotate at the same time through the grinding belt transmission component 150; the grinding belt transmission component 150 includes a grinding belt 151, a grinding driving wheel 152, a driven wheel and a grinding belt transmission bracket 154; the grinding driving wheel 152 and the driven wheel are respectively mounted on the bottom of two grinding carrier seats 123; the bottom end of one of the grinding carrier seats 123 is connected to the rotating drive member 121 through a coupling 125; the two ends of the grinding belt 151 are respectively mounted on the grinding driving wheel 152 and the driven wheel; the grinding driving wheel 152, the driven wheel and the rotating drive member 121 are all connected to the grinding belt transmission bracket 154.

[0058] The polishing belt drive bracket 154 can be composed of a plurality of small brackets; by adopting the polishing belt drive component 150, only one rotating drive member 121 can be used to drive two products 12 to rotate, and the polishing of the two products 12 can be completed at the same time, and the polishing speed is fast. Specifically, when the rotating drive member 121 rotates, it will drive the polishing driving wheel 152 to rotate, and the rotation of the polishing driving wheel 152 can drive the polishing driven wheel 153 to rotate through the polishing belt 151, so that the two polishing carriers 123 rotate synchronously.

[0059] like Figure 8-11As shown, in the fuel tank cap injection molding equipment described in this embodiment, the rotating mechanism 16 includes a pair of clamping parts 211 for clamping the product 12, a telescopic adjustment device for adjusting the distance between the two clamping parts 211, and a flipping part 230 for flipping the clamping parts 211; the telescopic adjustment device includes a main telescopic adjustment component and a secondary telescopic adjustment component respectively connected to the two clamping parts 211; the flipping part 230 includes a flipping power part 231, a main flipping shaft 232, and a secondary flipping shaft 233 , main flip support 234 and auxiliary flip support 235; the flip power member 231, the main flip support 234 and the auxiliary flip support 235 are all installed on the cooling machine 14; the main flip shaft 232 and the auxiliary flip shaft 233 are rotationally connected to the main flip support 234 and the auxiliary flip support 235 respectively; the output of the flip power member 231 is connected to the main flip shaft 232; the main telescopic adjustment component and the auxiliary telescopic adjustment component are connected to the main flip shaft 232 and the auxiliary flip shaft 233 respectively.

[0060] The clamping part 211 can be a common finger cylinder or clamping device on the market, and its structure is not limited, as long as it can realize the function of clamping the product 12. The telescopic adjustment device is a common telescopic adjustment device on the market, which can adjust the distance between the two clamping parts 211. Specifically, in order to ensure that the product 12 can be rotated smoothly, the height of the main flip support 234 and the auxiliary flip support 235 is set to be high enough for the product 12 to rotate, to prevent the product 12 from hitting the cooling machine 14 during rotation and causing the flip failure; initially, the distance between the two clamping parts 211 is adjusted by the main telescopic adjustment component and the auxiliary telescopic adjustment component to be sufficient to accommodate the product 12. When the product 12 needs to be rotated, the conveying mechanism 13 places the product 12 between the two clamping parts 211, and then the telescopic adjustment device adjusts the distance between the two clamping parts 211 so that the clamping parts 211 can approach and clamp the product 12. The clamping parts 211 will clamp the product 12 from both ends. After the clamping is firm, the conveying mechanism 13 releases the product 12; then, the flip power part 231 drives the main flip shaft 232 to connect. Since the two clamping parts 211 clamp the product 12 at the same time, the main flip shaft 232 rotates. When the product 12 moves, the auxiliary flip shaft 233 will be driven to rotate along the auxiliary flip support 235 at the same time. When the product 12 rotates to a suitable angle, for example, when the product 12 rotates to a certain degree, the flip power part 231 stops working, and then the robot grabs the product 12, and then the telescopic adjustment device and the clamping component 211 work at the same time, so that the clamping component 211 releases the product 12, and finally the conveying mechanism 13 puts the product 12 into the next process to ensure that the orientation of the product 12 meets the processing requirements of the next station, thereby realizing the automation of the tank cap flipping.

[0061] like Figure 8-11As shown, in the fuel tank cap injection molding device described in this embodiment, the flip component 230 further includes a main flip block 236, a secondary flip block 237, and a connecting rod 238 provided between the main flip block 236 and the secondary flip block 237; the main telescopic adjustment component is installed on the main flip block 236; the secondary telescopic adjustment component is installed on the secondary flip block 237;

[0062] Specifically, in actual use, some products 12 have poor rigidity. During the rotation process, due to the effect of torque, the product 12 may be broken or deformed, affecting the subsequent processing steps. By providing the main flip block 236, the auxiliary flip block 237 and the connecting rod 238, a stable support structure can be formed, which is conducive to the stable rotation of the product 12 and ensures that the product 12 will not be damaged.

[0063] like Figure 10-11 As shown, in the fuel tank cap injection molding device described in this embodiment, the main telescopic adjustment assembly includes a main push block 221, a main guide rail 222 and a main driving force piece 223 installed on the main flip block 236; the main guide rail 222 is slidably connected to the main flip block 236; the main guide rail 222 is connected to the main push block 221; the output end of the main driving force piece 223 is connected to the main push block 221; one of the clamping components 211 is installed on the main push block 221;

[0064] The main driving force member 223 can be a common cylinder; when it is necessary to reduce the distance between the two clamping components 211, keep one of the clamping components 211 stationary, and make the main driving force member 223 work, driving the main pushing block 221 connected to the output end of the main driving force member 223 to move forward, and the main guide rail 222 will slide forward along the main flip block 236, so that the main pushing block 221 can move forward smoothly; similarly, when it is necessary to increase the distance between the two clamping components 211, it is only necessary to retract the output end of the main driving force member 223.

[0065] like Figure 10-11 As shown, a fuel tank cap injection molding device described in this embodiment, the auxiliary telescopic adjustment component includes an auxiliary push block 224, an auxiliary guide rail 225 and an auxiliary driving force member 226 installed on the auxiliary flip block 237; the auxiliary guide rail 225 is slidably connected to the auxiliary flip block 237; the auxiliary guide rail 225 is connected to the auxiliary push block 224; the output end of the auxiliary driving force member 226 is connected to the auxiliary push block 224; another clamping component 211 is installed on the auxiliary push block 224.

[0066] The auxiliary driving member 226 can be a common cylinder; when the distance between the two clamping members 211 needs to be reduced, the other clamping member 211 is kept stationary, and the auxiliary driving member 226 is operated to drive the auxiliary push block 224 connected to the output end of the auxiliary driving member 226 to move forward, and the auxiliary guide rail 225 will slide forward along the auxiliary flip block 237, so that the auxiliary push block 224 can move forward smoothly; similarly, when the distance between the two clamping members 211 needs to be increased, it is only necessary to retract the output end of the auxiliary driving member 226. The clamping speed can be accelerated by setting the auxiliary telescopic adjustment component.

[0067] like Figure 10-11 As shown, in the fuel tank cap injection molding equipment described in this embodiment, each of the clamping parts 211 is provided with a flip anti-skid pad 214; the provision of the flip anti-skid pad 214 can prevent the product 12 from slipping and falling during the rotation process.

[0068] like Figure 10-11 As shown, in the fuel tank cap injection molding equipment described in this embodiment, the clamping component 211 is a finger cylinder; the use of the finger cylinder can reduce the occupied space while ensuring the clamping of the product 12, thereby improving the compactness of the whole machine.

[0069] like Fig. 9 , 13 As shown in 14, the fuel tank cap injection molding equipment described in this embodiment, the rotating mechanism 16 also includes a positioning component 240; a positioning slot 241 is provided on the cooling table 14; the positioning slot 241 is located between the two clamping parts 211; the positioning component 240 includes a base plate 242, a first lifting guide column 243, a support plate 244, a first lifting cylinder 245 and a positioning carrier 246 arranged on the support plate 244; one end of the first lifting guide column 243 is connected to the bottom surface of the cooling table 14; the other end of the first lifting guide column 243 is connected to the base plate 242; the first lifting cylinder 245 is installed on the base plate 242; the support plate 244 is arranged above the base plate 242; the output end of the first lifting cylinder 245 is connected to the support plate 244, and the first lifting cylinder 245 is used to drive the support plate 244 to rise and fall in the positioning slot 241.

[0070] The positioning carrier 246 is provided with a groove that matches the shape of the product 12. More preferably, the groove can be compatible with both the front and back shapes of the product 12. If a robot is used for loading, it may be necessary to equip the robot with an additional device for positioning. By setting the positioning assembly 240, since the height and position of the lifting of the support plate 244 are specified, it is beneficial to cooperate with the clamping component 211, making the clamping step more accurate and stable. Specifically, before clamping, the support plate 244 will be lifted by the first lifting cylinder 245 to a position higher than the positioning slot 241 and between the two clamping components 211, and then the robot loads the product; the robot places the product 12 on the positioning carrier 246; since the position of the positioning carrier 246 is fixed, the clamping component 211 can accurately clamp the product 12 of the positioning carrier 246 every time. After the clamping component 211 stably clamps the product 12, the first lifting cylinder 245 drives the positioning carrier 246 to descend to a position below the positioning slot 241 to prevent the product 12 or the device from being damaged by colliding with the positioning component 240 during rotation; when the product 12 finishes rotating, the product 12 can be removed directly from the clamping component 211 manually or by a robot, or the positioning carrier 246 can be raised, the product 12 can be placed on the positioning carrier 246, and then removed by a robot.

[0071] like Fig. 9 , 13 As shown in 14, the tank cap injection molding equipment described in this embodiment, the positioning assembly 240 also includes a two-stage lifting component; the first lifting cylinder 245 is connected to the support plate 244 through the two-stage lifting component; the two-stage lifting component includes a lifting plate 247, a second lifting cylinder 248 and a second lifting guide column 249; the lifting plate 247 is slidably connected to the first lifting guide column 243; the output end of the first lifting cylinder 245 is connected to the bottom of the lifting plate 247; the second lifting cylinder 248 is installed on the lifting plate 247; the output of the second lifting cylinder 248 is connected to the bottom of the support plate 244; the second lifting guide column 249 is connected to the support plate 244, and the second lifting guide column 249 is slidably connected to the lifting plate 247.

[0072] By setting up a two-stage lifting component, the first lifting cylinder 245 roughly lifts the position of the positioning carrier 246, and the second lifting cylinder 248 accurately positions the height of the positioning carrier 246, so as to improve the accuracy of lifting the positioning carrier 246.

[0073] like Fig.12 , 15As shown in Figure 16, the fuel tank cap injection molding equipment described in this embodiment, the folding water outlet mechanism 17 includes two fixed plates 311, two torsion plates 314, two torsion carriers 313, a torsion power component for driving the two torsion plates 314 to rotate, and a water outlet clamping component for clamping the water outlet residual material 315; the two torsion carriers 313 are respectively arranged on the two torsion plates 314; both ends of each torsion plate 314 are respectively rotatably connected to the two fixed plates 311; the torsion power component and the water outlet clamping component are both installed on the fixed plate 311.

[0074] Specifically, the torsion power component can be a common motor or electric motor on the market, and its structure is not limited, as long as it can realize the function of rotating the two torsion plates 314. The nozzle clamping component can be a common cylinder on the market, and its structure is not limited, as long as it can realize the function of clamping the nozzle residue 315. During operation, the two products 12 with the nozzle residue 315 will be placed on two horizontally oriented torsion carriers 313, and then the nozzle clamping component clamps the nozzle residue 315 to ensure that the nozzle residue 315 is fixed. Then, the torsion power component drives the two torsion plates 314 to rotate at the same time, specifically, they can rotate in opposite directions. Under the action of shear force, the nozzle residue 315 is broken, and then the torsion power component drives the two torsion plates 314 to rotate in the opposite direction and reset to the original position, and then the nozzle clamping component releases the nozzle residue 315, and the nozzle residue 315 falls naturally, completing the nozzle folding process.

[0075] like Figure 15-16 As shown, in the fuel tank cap injection molding equipment described in this embodiment, the nozzle clamping assembly includes two nozzle clamping cylinders 321 respectively arranged on two fixing plates 311; the two nozzle clamping cylinders 321 are arranged opposite to each other;

[0076] Specifically, the use of two nozzle clamping cylinders 321 disposed opposite to each other is conducive to keeping the nozzle surplus material 315 fixed when the two torsion plates 314 rotate towards each other, and the nozzle surplus material 315 can be broken smoothly.

[0077] like Figure 15-16 As shown, in the fuel tank cap injection molding equipment described in this embodiment, the nozzle clamping cylinder 321 is provided with a nozzle anti-slip pad 322;

[0078] Specifically, the use of the nozzle anti-slip pad 322 is conducive to keeping the nozzle surplus material 315 fixed when the two torsion plates 314 rotate towards each other, and the nozzle surplus material 315 can be broken smoothly.

[0079] like Figure 15-16As shown, in the fuel tank cap injection molding device described in this embodiment, the torsion power assembly includes a torsion motor 331, a first transmission gear 332 and a second transmission gear 333; the first transmission gear 332 is sleeved on one end of one of the torsion carriers 313; the second transmission gear 333 is sleeved on one end of the other torsion carrier 313; the first transmission gear 332 is meshed with the second transmission gear 333; the output end of the torsion motor 331 is connected to the other end of one of the torsion carriers 313;

[0080] During operation, the torsion motor 331 can drive the torsion carrier 313 connected to the first transmission gear 332 to rotate; since the first transmission gear 332 is meshed with the second transmission gear 333, when the first transmission gear 332 rotates, it can drive the second transmission gear 333 and the first transmission gear 332 to move in the opposite direction, and can drive the two torsion carriers 313 to move in the opposite direction relative to each other, so that the water outlet residual material 315 can be cut off.

[0081] like Figure 15-16 As shown, in the fuel tank cap injection molding device described in this embodiment, the output end of the torsion motor 331 is connected to the other end of one of the torsion carriers 313 through a torsion belt 336 transmission component; the torsion belt 336 transmission component includes a torsion driving wheel 334, a torsion driven wheel 335 and a torsion belt 336; the two ends of the torsion belt 336 are respectively sleeved on the torsion driving wheel 334 and the torsion driven wheel 335; the torsion driven wheel 335 is sleeved on the other end of the torsion carrier 313; the torsion driving wheel 334 is sleeved on the output end of the torsion motor 331;

[0082] When the torsion motor 331 is working, it will drive the torsion driving wheel 334 to rotate, and then transmit it to the torsion driven wheel 335 through the torsion belt 336, thereby driving the torsion carrier 313 to rotate; by setting the torsion belt 336 transmission component, the torsion motor 331 can be installed in a suitable place, so as to improve the overall compactness.

[0083] like Figure 15-16 As shown, in the fuel tank cap injection molding device described in this embodiment, the folding water outlet mechanism 17 further includes a water outlet collecting guide plate 341 connected to the fixing plate 311; the water outlet collecting guide plate 341 is arranged below the water outlet clamping assembly;

[0084] Specifically, during operation, a waste material collection bucket can be placed at the output end of the nozzle collecting guide plate 341, and the fallen nozzle waste materials 315 can be collected together to keep the work area clean.

[0085] like Figure 15-16As shown, in the tank cap injection molding equipment described in this embodiment, baffles 342 are provided on both sides of the water inlet collecting guide plate 341.

[0086] It is used to prevent the nozzle residual material 315 from flying to other places and affecting the normal operation of the equipment.
