[0022] In this embodiment, the horizontal conveying device 6 is arranged on the back side of the lower mold 1 .

[0023] Please refer to Figure 8When the upper mold assembly 2 and the lower mold 1 need to be sprayed with lubricating oil, the angle adjustment device 4 drives the mounting tube 43 to rotate counterclockwise by ninety degrees, so that the upper oil spray pipe 31 and the lower oil spray pipe 32 are located between the upper mold assembly 2 and the lower mold 1, and are initially located at one end of the upper mold assembly 2 and the lower mold 1. The horizontal conveying device 6 conveys the angle adjustment device 4, driving the upper oil spray pipe 31 and the lower oil spray pipe 32 to follow the movement, wherein the lubricating oil is sprayed from the nozzle 33 of the upper oil spray pipe 31 to the upper mold assembly 2, and the lubricating oil is sprayed from the nozzle 33 of the lower oil spray pipe 32 to the lower mold 1. Since the horizontal conveying device 6 can convey the upper oil spray pipe 31 at a uniform speed, the lubricating oil is sprayed from the nozzle 33 of the lower oil spray pipe 32 to the lower mold 1. 1 and the lower oil spray pipe 32 spray lubricating oil on the upper mold assembly 2 and the lower mold 1, thereby improving the uniformity of lubricating oil spraying, and the distance between the upper mold assembly 2 and the nozzle 33 of the upper oil spray pipe 31 can be adjusted, so that the nozzle 33 can be close to the part to be sprayed on the upper mold assembly 2, so that the sprayed atomized oil can be better attached to the upper mold assembly 2, thereby reducing the atomized lubricating oil from falling to other positions, and at the same time, by setting the receiving part 5, the two receiving boxes 52 are located on both sides of the upper oil spray pipe 31, and the atomized lubricating oil that falls can be received and recovered, thereby further reducing the waste of lubricating oil.

[0024] in, Figure 8 The arrows in the figure indicate that the upper oil spray pipe 31 and the lower oil spray pipe 32 move horizontally between the upper mold assembly 2 and the lower mold 1 to spray lubricating oil on the upper mold assembly 2 and the lower mold 1 respectively.

[0025] Among them, the oil injection assembly 3 also includes a lubricating oil storage container, two flow controllers and two oil pumps (not shown in the figure). The liquid inlet pipe heads 34 of the upper oil injection pipe 31 and the lower oil injection pipe 32 are respectively connected to the output ends of the corresponding oil pumps through oil delivery hoses, and the input end of the oil pump is connected to the lubricating oil storage container through a pipeline. The oil delivery hose has a sufficient length to meet the distance required for the upper oil injection pipe 31 and the lower oil injection pipe 32 to move. The flow controller is installed on the corresponding oil delivery pipeline to cooperate with the oil pump to adjust the flow rate of the injected lubricating oil.

[0026] After the oil spraying of the upper mold assembly 2 and the lower mold 1 is completed, the horizontal conveying device 6 conveys the angle adjustment device 4 to drive the oil spray assembly 3 to move to one side of the lower mold 1 and the upper mold assembly 2, and the angle adjustment device 4 drives the mounting tube 43 to drive the upper oil spray pipe 31 and the lower oil spray pipe 32 to rotate ninety degrees clockwise, so that the upper oil spray pipe 31 and the lower oil spray pipe 32 are retracted to one side of the lower mold 1, so that when the sheet metal product to be processed is processed multiple times, the upper oil spray pipe 31 and the lower oil spray pipe 32 will not affect the loading and unloading of the sheet metal product by the configured automatic loading and unloading equipment (such as a robot, etc.), especially for Figure 1 As shown, sheet metal products are loaded and unloaded from the left and right directions of the lower die 1.

[0027] In this embodiment, the nozzle 33 is an atomizing nozzle, and both ends of the upper fuel injection pipe 31 and the lower fuel injection pipe 32 are blocked.

[0028] As an optional mode of this embodiment, the fuel injection assembly 3 further includes two angle adjustment motors for adjusting the injection angle of the nozzle 33; in this case, the upper fuel injection pipe 31 and the lower fuel injection pipe 32 are both rotatably mounted on the mounting tube 43, and one angle adjustment motor is correspondingly connected to the upper fuel injection pipe 31 or the lower fuel injection pipe 32 through a gear set. Thus, the injection angles of the nozzles 33 on the upper fuel injection pipe 31 and the lower fuel injection pipe 32 can be controlled respectively, and the angle adjustment motors are correspondingly mounted on the mounting tube 43 through brackets.

[0029] In this embodiment, the oil drain pipe head 53 in the receiving member 5 is connected to the collecting container through a pipeline. The collecting container can be installed on the mounting frame 41 and located below the oil drain pipe head 53 (not shown in the figure), so as to facilitate the movement with the injection assembly 3; the two ends of the connecting portion 51 are correspondingly connected to the upper injection pipe 31 through connecting parts, so as not to affect the discharge of the collected lubricating oil through the oil drain pipe head 53.

[0030] The lubricating oil collected in the collection container can subsequently be tested and recycled based on the test results, or can be used further after being processed.

[0031] In this embodiment, the mounting frame 41 is a C-shaped frame, the motor 42 is mounted on the top of the mounting frame 41, and the driving shaft 421 passes through the top of the mounting frame 41 and is rotatably connected to the bottom of the mounting frame 41.

[0032] In other embodiments, the mounting frame 41 may also be an L-shaped frame, in which case the motor 42 is mounted at the bottom of the mounting frame 41 , and the drive shaft 421 passes through the bottom of the L-shaped frame.

[0033] See also Figure 1 and Figure 2 The upper mold assembly 2 includes a hydraulic device 21, an upper mold part 22 and a positioning sleeve 23. The hydraulic device 21 is installed inside the installation cabinet 20. The output end of the hydraulic device 21 passes through the bottom of the installation cabinet 20 and is connected to the upper mold part 22. Positioning sleeves 23 are installed at the four corners of the upper mold part 22. A plurality of limiting columns 201 are installed at the bottom of the installation cabinet 20. A plurality of positioning columns 11 are installed on the top of the base 10. The positioning columns 11, the limiting columns 201 and the positioning sleeves 23 are arranged in a one-to-one correspondence, and the positioning sleeves 23 are sleeved on the limiting columns 201.

[0034] The hydraulic device 21 controls the lifting and lowering of the upper mold 22 and provides downward pressure; by setting the positioning column 11, the positioning sleeve 23 and the limiting column 201, when the hydraulic device 21 pushes the upper mold 22 downward, the positioning sleeve 23 moves downward along the limiting column 201, and before the positioning sleeve 23 is separated from the limiting column 201, the bottom end of the positioning sleeve 23 is sleeved on the positioning column 11, so that during the entire process of the upper mold 22 descending, the positioning sleeve 23 can cooperate with the limiting column 201 and the positioning column 11 for guiding and positioning, so that the upper mold 22 can be accurately aligned with the lower mold 1 for stamping and forming the sheet metal part to be processed.

[0035] The upper mold 22 and the punch shape and the cavity shape of the lower mold 1 are specifically set according to the shape of the automobile parts to be processed, such as automobile engine hood, car door, trunk cover, mailbox shell protective plate, etc.; In this embodiment, the upper mold 22 is a male mold and the lower mold 1 is a female mold; The upper mold 22 includes an assembly plate and a punch module. The punch module is installed at the output end of the hydraulic equipment 21 through the assembly plate. Four positioning sleeves 23 are correspondingly installed at the four corners of the assembly plate. The rectangle formed by the center line of the four positioning sleeves 23 is larger than the area of ​​the punch module. The rectangle formed by the center line of the corresponding four positioning columns 11 is larger than the cavity area of ​​the lower mold 1, so as not to affect the automatic loading and unloading of the processed sheet metal products by the automatic loading and unloading equipment.

[0036] The bottom of the installation cabinet 20 is supported by four legs, and the distance between two adjacent legs is greater than the length of the upper mold assembly 2 and the lower mold 1.

[0037] Preferably, each limiting column 201 is sleeved with a spring 12, so that when the hydraulic device 21 pushes down the upper mold 22 to interact with the lower mold 1, the impact force of the upper mold assembly 2 is buffered and absorbed.

[0038] See also Figure 2 and Figure 3 As a preferred embodiment of this embodiment, the automobile sheet metal stamping device also includes a second mounting plate 40, which is mounted on the mounting cabinet 20 and is located below the first mounting plate 30, and the bottom of the mounting frame 41 is slidably connected to the first mounting plate 30.

[0039] By slidably connecting the mounting frame 41 to the first mounting plate 30, the first mounting plate 30 supports the mounting frame 41, thereby improving the stability of the mounting frame 41 in the process of following the movement of the horizontal conveying device 6, that is, improving the stability of the oil spraying assembly 3 in spraying lubricating oil.

[0040] A slide rail is arranged on the second mounting plate 40 , and a slide sleeve is correspondingly arranged at the bottom of the mounting frame 41 , and a pulley is installed inside the slide sleeve. The slide sleeve is sleeved on the slide rail, and the pulley slides into the slide cavity of the slide rail.

[0041] See also Figures 4 to 6 As a preferred embodiment of the present invention, the connecting portion 51 is made of a deformable material, an arc-shaped hole 521 is provided on the receiving box 52, and the automobile sheet metal stamping device further includes a folding device 7, and the folding device 7 is used to drive the two receiving boxes 52 to rotate.

[0042] By setting the connecting portion 51 to a deformable material, after the oil spraying assembly 3 finishes spraying lubricating oil on the upper mold assembly 2 and the lower mold 1, the folding device 7 can drive the two receiving boxes 52 to rotate upward and close together. Figure 7 (a) By closing the two receiving boxes 52 together, the lubricating oil collected and attached to the wall of the receiving box 52 can quickly flow to the connecting portion 51, and then can be quickly discharged through the oil drain pipe head 53; At the same time, since the nozzle 33 on the upper oil injection pipe 31 opens upward and dust is easily dropped in, the two receiving boxes 52 are closed together to protect the nozzle 33 on the upper oil injection pipe 31, thereby preventing dust from dropping on the nozzle 33 and falling into the interior of the two receiving boxes 52 to contaminate the collected lubricating oil; The connecting portion 51 may be made of rubber, silicone, leather, etc., and flanges are provided at both ends of the connecting portion 51 to prevent the collected lubricating oil from flowing out through the two ends of the connecting portion 51 .

[0043] As an optional method of this embodiment, the folding device 7 includes a fixed frame, two rotating motors, two transmission members and two rotating shafts (not shown in the figure), the fixed frame is installed on the mounting tube 43, the two rotating motors are installed on both sides of the fixed frame, and the two rotating shafts are correspondingly installed on the outer bottom of the two receiving boxes 52, each rotating shaft is connected to the output shaft of the corresponding rotating motor through the corresponding transmission member, and the two rotating motors are used to drive the two receiving boxes 52 to rotate to achieve opening and closing.

[0044] The transmission parts can be a belt and a pulley or a synchronous wheel and a synchronous belt, etc.

[0045] See also Figure 4 and Figure 5 As another optional method of this embodiment, the folding device 7 includes a connecting handle 71, a lifting device 73 and two support rods 72. The two support rods 72 are installed at both ends of the connecting handle 71, and the two support rods 72 are respectively located on both sides of the upper fuel injection pipe 31. The lifting device 73 is used to lift the connecting handle 71.

[0046] When the two receiving boxes 52 need to be closed, the lifting device 73 lifts the connecting handle 71, and the connecting handle 71 drives the two supporting rods 72 to move upward, and the two supporting rods 72 correspondingly lift the two receiving boxes 52, so that the two receiving boxes 52 rotate upward to close, and the arc-shaped hole 521 on the receiving box 52 is sleeved on the upper fuel injection pipe 31, and the connecting portion 51 covers the upper fuel injection pipe 31 upward; When the lower mold 1 and the upper mold assembly 2 are sprayed with lubricating oil, the lifting device 73 lowers the connecting handle 71, driving the two supporting rods 72 to lower. At this time, the two receiving boxes 52 rotate downward and unfold by gravity and the elastic restoring force of the connecting part 51. Figure 7 As shown in (b); after the two receiving boxes 52 are opened, the two support rods 72 support the two receiving boxes 52.

[0047] The entire folding device 7 is simplified, and the folding device 7 is easier to install and configure.

[0048] In this embodiment, the side walls of the two receiving boxes 52 are slightly inclined to form an inverted eight-shape, which cooperates with the elastic restoring force of the connecting part 51. Therefore, after the two support rods 72 are lowered, the two receiving boxes 52 are more likely to rotate downward by gravity to achieve the purpose of opening.

[0049] As an optional manner of this embodiment, the lifting device 73 is a cylinder or a hydraulic cylinder, etc. The lifting device 73 is installed on the mounting tube 43 through a fixing frame, and the output end of the lifting device 73 is connected to the connecting handle 71.

[0050] See also Figure 5 As another optional mode of this embodiment, the lifting device 73 includes a threaded shaft 731, a nut 732, a slide bar 734, two clamping blocks 733 and a rotating device 735. The threaded shaft 731 is rotatably mounted on the second mounting plate 40. The nut 732 is threadedly connected to the threaded shaft 731. The slide bar 734 is mounted on the first mounting plate 30 through a mounting block. The nut 732 is sleeved on the slide bar 734 through an ear. The two clamping blocks 733 are installed on the nut 732 at intervals and are located on the upper and lower sides of the connecting handle 71. The rotating device 735 is used to drive the threaded shaft 731 to rotate. The automobile sheet metal stamping device also includes a support member 8, which includes a support plate 81 and a positioning rod 82. The support plate 81 is sleeved and fixed on the mounting tube 43, the bottom end of the positioning rod 82 is installed on the support plate 81, and the top end of the positioning rod 82 passes through the connecting handle 71.

[0051] A clamping cavity is formed between the two clamping blocks 733 .

[0052] By adopting a threaded lifting structure, the use of hydraulic cylinders, air cylinders, etc. is avoided, so there is no need to equip hydraulic stations, air pressure stations, etc., which simplifies the driving equipment and eliminates the need for the configuration of oil pipes or air pipes, thereby avoiding the oil pipes or air pipes from getting entangled or folded when the angle adjustment device 4 rotates and the horizontal conveying device 6 is transported. By setting the lifting device 73 on the second mounting plate 40 to avoid installation on the mounting pipe 43, the load on the angle adjustment device 4 and the horizontal conveying device 6 can be reduced.

[0053] When it is necessary to close the two receiving boxes 52, the spraying of lubricating oil on the upper mold assembly 2 and the lower mold 1 is completed, the angle adjustment device 4 rotates the upper oil spray pipe 31 and the lower oil spray pipe 32 ninety degrees to one side of the lower mold 1, and the connecting handle 71 faces the clamping cavity. At this time, the horizontal conveying device 6 conveys the oil spray assembly 3 toward the clamping block 733, so that the connecting handle 71 is inserted into the clamping cavity.

[0054] Then the rotating device 735 drives the threaded shaft 731 to rotate clockwise, and the nut 732 drives the clamping block 733 to move upward along the sliding rod 734, thereby driving the connecting handle 71 to move upward, and the connecting handle 71 drives the two supporting rods 72 to move upward and push the two receiving boxes 52 to rotate upward and close; wherein, the connecting handle 71 moves upward along the positioning rod 82; When the two receiving boxes 52 need to be unfolded later, the rotating device 735 drives the threaded shaft 731 to rotate in the opposite direction. At this time, the nut 732 drives the clamping block 733 to move down, and the clamping block 733 drives the connecting handle 71 to descend, and the two support rods 72 to descend. At this time, the two receiving boxes 52 rotate downward to unfold. The connecting handle 71 drives the support rod 72 to move down to the support plate 81, and the support plate 81 supports the connecting handle 71 and the support rod 72. Fig.10 (a) to Fig.10 (b).

[0055] As a preferred method of this example, the groove spacing of the clamping cavity is greater than the thickness value of the connecting handle 71, and a convex shaft is provided on the clamping block 733 located below, and a corresponding assembly groove is opened on the connecting handle 71. When the connecting handle 71 is lifted by the clamping block 733 below, the convex shaft is first inserted into the assembly groove, thereby being able to drive the connecting handle 71 to move upward more stably.

[0056] See also Figure 4 and Figure 5 As a preferred embodiment of the present invention, the number of the positioning rods 82 is set to be multiple, and the multiple positioning rods 82 are installed on the support plate 81 at intervals, and the multiple positioning rods 82 respectively penetrate the support rod 72 and the connecting handle 71.

[0057] By providing a plurality of positioning rods 82 to limit the support rod 72 and the connecting handle 71 , the stability of the connecting handle 71 and the support rod 72 during vertical movement is improved.

[0058] In this embodiment, there are four positioning rods 82 , which are respectively located at the four corners of the support plate 81 and correspondingly penetrate the two support rods 72 and the two sides of the connecting handle 71 .

[0059] As an optional method of this example, the rotating device 735 includes a bracket, a driving motor and a gear set. The driving motor is mounted on the second mounting plate 40 through the bracket, and the output shaft of the driving motor is set downward. The gear set transmission connects the output shaft of the driving motor and the threaded shaft 731.

[0060] Please refer again Figure 5 As another optional method of this example, the rotating device 735 is a slave gear, which is installed at the bottom of the threaded shaft 731. The main gear 44 is installed at the bottom end of the driving shaft 421 and below the mounting tube 43. A plurality of sliders 422 are installed around the driving shaft 421 and above the main gear 44. A plurality of key slots 432 are provided at the bottom of the mounting tube 43 corresponding to the sliders 422. The key slots 432 are sleeved on the sliders 422 to form a sliding key connection. A driving plate 431 is installed at the bottom end of the mounting tube 43. The automobile sheet metal stamping device further comprises an F-shaped frame 9, one end of which is mounted on the first mounting plate 30, and ends of two arms 91 of the F-shaped frame 9 are both configured as inclined surfaces; When the horizontal conveying device 6 conveys the angle adjustment device 4, so that the angle adjustment device 4 drives the connecting handle 71 to be inserted between the two clamping blocks 733 through the support member 8, the main gear 44 engages with the rotating device 735, and the two support arms 91 of the F-shaped frame 9 are sleeved on the driving shaft 421 and push up the driving disk 431 to separate the mounting tube 43 from the slider 422.

[0061] Please refer to Fig. 9 and Fig.10 After the lubricating oil coating is completed, the angle adjustment device 4 rotates the upper oil injection pipe 31 and the lower oil injection pipe 32 by ninety degrees so that they are located on one side of the lower mold 1. At this time, the connecting handle 71 faces the clamping cavity, and the horizontal conveying device 6 continues to convey the rotating device 735, driving the connecting handle 71 to insert into the clamping cavity through the support member 8. At the same time, the main gear 44 meshes with the rotating device 735 (slave gear), and in this process, the inclined surfaces at the ends of the two support arms 91 of the F-shaped frame 9 push up the two sides of the driving plate 431, and the driving plate 431 drives the mounting tube 43 to move upward, so that the key groove 432 on the mounting tube 43 is separated from the slider 422; the support arm 91 is supported by the driving plate 431, thereby supporting the mounting tube 43; When the subsequent motor 42 drives the driving shaft 421 to rotate again, the driving shaft 421 drives the main gear 44 to rotate, and the main gear 44 drives the threaded shaft 731 to rotate through the rotating device 735 (slave gear), thereby driving the connecting handle 71 to rise and fall, and realizing the function of driving the two receiving boxes 52 to open and close; at this time, the mounting tube 43 does not rotate.

[0062] The horizontal conveying device 6 then conveys the angle adjusting device 4 away from the lifting device 73, so that the main gear 44 is separated from the rotating device 735 (slave gear), the connecting handle 71 is separated from the clamping cavity, and the F-shaped frame 9 is separated from the driving plate 431, so that the mounting tube 43 descends, and the key slot 432 is again sleeved on the slider 422 to achieve the sliding key connection. The subsequent driving shaft 421 can drive the mounting tube 43 to rotate again, as shown in FIG. Fig.10 (c).

[0063] in, Fig.10 The downward arrow in (c) indicates that the F-shaped frame 9 is separated from the driving plate 431, and the mounting tube 43 descends due to gravity. The rotating arrow indicates that the subsequent driving shaft 421 can drive the mounting tube 43 to rotate again.

[0064] Therefore, in the present embodiment, the angle adjustment device 4 has the function of driving the upper fuel injection pipe 31 and the lower fuel injection pipe 32 to rotate and adjust their positions, and driving the threaded shaft 731 to rotate to realize the function of driving the two receiving boxes 52 to open and close, and the switching of the two functions is achieved in the process that the horizontal conveying device 6 conveys the angle adjustment device 4, inserts the connecting handle 71 into the clamping cavity, the main gear 44 engages with the rotating device 735 (slave gear), and the inclined surfaces of the ends of the two support arms 91 of the F-shaped frame 9 push up the drive plate 431 to drive the mounting tube 43 to move upward, so that the key slot 432 is separated from the slider 422, and there is no need to set up an additional driving device to switch the functions.

[0065] The number of the sliders 422 is not less than two. In this embodiment, the number of the sliders 422 is four, and the number of the corresponding key slots 432 is four.

[0066] See also Fig. 9 A supporting portion is provided at the bottom end of the slider 422 , and when the keyway 432 is assembled with the slider 422 , the supporting portion is used to support the mounting tube 43 .

[0067] By providing the support portion, the bottom end of the mounting tube 43 is prevented from acting on the main gear 44; Furthermore, preferably, a ball bearing is embedded in the support portion, so as to reduce the friction between the mounting tube 43 and the support portion when the mounting tube 43 rotates.

[0068] Please refer again Fig. 9The tops of the two arms 91 of the F-shaped frame 9 are both provided with arc-shaped protrusions 911 , and the bottom of the driving plate 431 is correspondingly provided with an arc-shaped groove (not shown in the figure).

[0069] When the support arm 91 supports both sides of the driving disk 431, the arc-shaped protrusion 911 is correspondingly embedded in the arc-shaped groove, thereby having a certain limiting effect on the axial direction of the driving disk 431. Therefore, when the motor 42 drives the main gear 44 to rotate through the driving shaft 421, the mounting tube 43 can be better kept stationary, so that the subsequent key slot 432 can be better aligned with the slider 422.

[0070] Since the arc-shaped protrusion 911 is provided, when the driving plate 431 is separated from the F-shaped frame 9, the arc-shaped protrusion and the groove wall of the arc-shaped groove act to slightly lift the mounting tube 43, so that the arc-shaped protrusion is separated from the arc-shaped groove.

[0071] The inner wall of the mounting tube 43 and the surface of the driving shaft 421 are both smooth.

[0072] In this embodiment, the horizontal conveying device 6 is a belt conveying device, which includes a mounting box, a driving motor, a conveyor belt 61, a connecting block 62 and two pulleys. The mounting box is mounted on the first mounting plate 30, and a strip opening is provided on the side of the mounting box facing the angle adjustment device 4. The two pulleys are rotatably mounted on both sides of the inside of the mounting box. The conveyor belt 61 is connected to the two pulleys for transmission. The driving motor is mounted on the mounting box, and the output end of the driving motor passes through the mounting box and is connected to a pulley. The connecting block 62 connects the conveyor belt 61 and the mounting frame 41.

[0073] In other embodiments, the horizontal conveying device 6 may also adopt a screw conveying structure, etc.

[0074] The working principle of the automobile sheet metal stamping device provided by the present invention is as follows: Please refer to Figure 8 When the upper mold assembly 2 and the lower mold 1 need to be sprayed with lubricating oil, the angle adjustment device 4 drives the mounting tube 43 to rotate counterclockwise by ninety degrees, so that the upper oil spray pipe 31 and the lower oil spray pipe 32 are located between the upper mold assembly 2 and the lower mold 1, and are initially located at one end of the upper mold assembly 2 and the lower mold 1, and the horizontal conveying device 6 conveys the angle adjustment device 4, driving the upper oil spray pipe 31 and the lower oil spray pipe 32 to follow the movement, wherein the lubricating oil is sprayed from the nozzle 33 of the upper oil spray pipe 31 to the upper mold assembly 2, and the lubricating oil is sprayed from the nozzle 33 of the lower oil spray pipe 32 to the lower mold 1; The two receiving boxes 52 are unfolded and located on both sides of the upper oil injection pipe 31, and can receive and recover the atomized and falling lubricating oil, thereby further reducing the waste of lubricating oil.

[0075] Please refer to Fig. 9 and Fig.10After the lubricating oil coating is completed, the angle adjustment device 4 rotates the upper oil injection pipe 31 and the lower oil injection pipe 32 by ninety degrees so that they are located on one side of the lower mold 1. At this time, the connecting handle 71 faces the clamping cavity, and the horizontal conveying device 6 continues to convey the rotating device 735, driving the connecting handle 71 to insert into the clamping cavity through the support member 8. At the same time, the main gear 44 meshes with the rotating device 735 (slave gear), and in this process, the inclined surfaces at the ends of the two support arms 91 of the F-shaped frame 9 push up the two sides of the driving plate 431, and the driving plate 431 drives the mounting tube 43 to move upward, so that the key groove 432 on the mounting tube 43 is separated from the slider 422; the support arm 91 is supported by the driving plate 431, thereby supporting the mounting tube 43; When the subsequent motor 42 drives the driving shaft 421 to rotate again, the driving shaft 421 drives the main gear 44 to rotate, and the main gear 44 drives the threaded shaft 731 to rotate through the rotating device 735 (slave gear), thereby driving the connecting handle 71 to rise and fall, and realizing the function of driving the two receiving boxes 52 to open and close; at this time, the mounting tube 43 does not rotate.

[0076] Specifically: the threaded shaft 731 rotates clockwise, the nut 732 drives the clamping block 733 to move upward along the slide rod 734, thereby driving the connecting handle 71 to move upward, the connecting handle 71 drives the two support rods 72 to move upward, and pushes the two receiving boxes 52 to rotate upward and close, the arc hole 521 on the receiving box 52 is sleeved on the upper injection pipe 31, and the connecting part 51 covers the upper injection pipe 31 upward, wherein the connecting handle 71 moves upward along the positioning rod 82; When the two receiving boxes 52 need to be unfolded later, the threaded shaft 731 rotates in the opposite direction, and the nut 732 drives the clamping block 733 to move downward, and the clamping block 733 drives the connecting handle 71 to descend, and the two supporting rods 72 descend. At this time, the two receiving boxes 52 rotate downward and unfold by gravity and the elastic restoring force of the connecting part 51. Figure 7 As shown in (b); after the two receiving boxes 52 are opened, the two support rods 72 support the two receiving boxes 52. The connecting handle 71 drives the support rod 72 to move down to the support plate 81, and the support plate 81 supports the connecting handle 71 and the support rod 72; The subsequent horizontal conveying device 6 conveys the angle adjustment device 4 away from the lifting device 73, so that the main gear 44 is separated from the rotating device 735 (slave gear), the connecting handle 71 is separated from the clamping cavity, and the F-shaped frame 9 is separated from the driving plate 431, so that the mounting tube 43 descends, and the keyway 432 is again sleeved on the slider 422 to realize the sliding key connection. The subsequent driving shaft 421 can drive the mounting tube 43 to rotate again to adjust the positions of the upper injection pipe 31 and the lower injection pipe 32.

[0077] Therefore, the angle adjustment device 4 has the function of driving the upper injection pipe 31 and the lower injection pipe 32 to rotate and adjust their positions, and drives the threaded shaft 731 to rotate to realize the function of driving the two receiving boxes 52 to open and close, and the switching of the two functions is achieved in the process that the horizontal conveying device 6 conveys the angle adjustment device 4, inserts the connecting handle 71 into the clamping cavity, the main gear 44 engages with the rotating device 735 (slave gear), and the inclined surfaces of the ends of the two support arms 91 of the F-shaped frame 9 push up the drive plate 431 to drive the mounting tube 43 to move upward, so that the key slot 432 is separated from the slider 422, and there is no need to set up an additional driving device to switch the functions.
