Description

Technical Field

[0001] The present invention relates to the technical field of injection mold welding, in particular to an injection mold welding device. Background Art

[0002] An injection mold is a tool used to process thermoplastic or thermosetting plastics into finished products through the injection molding process. It is a core component of injection molding production, determining the shape, dimensional accuracy, surface quality, and functional characteristics of the product.

[0003] At present, after long-term use, the existing injection molds will cause certain damage due to various reasons. The existence of these damages affects the use of the mold itself, and it is necessary to use welding to repair the damaged parts of the mold. Commonly used repair welding methods include manual welding, laser welding, etc. These welding methods have the following problems when working: First, the existing injection mold repair welding is almost always carried out in an exposed environment, which causes the material to evaporate and gasify due to intense heating during the welding process, and various toxic metal fumes will be generated. At the same time, high-power laser welding will also generate laser radiation, which is non-ionizing radiation. Long-term exposure to such an environment will cause damage to the human respiratory system and eyes.

[0004] Secondly, when repairing the existing injection mold, if there is damage on multiple sides, the mold needs to be flipped after the repair is completed on one side, and the repair work on the other side is carried out. Currently, the mold is generally flipped manually during the welding process. This is OK when encountering small molds. Once a heavier mold is encountered, there is a certain risk when flipping it manually, and the manual operation efficiency is not high. At the same time, if the mold placement angle is deflected, it needs to be moved manually, which is time-consuming and labor-intensive. Therefore, in response to the above-mentioned existing problems, the present application provides an injection mold welding device for optimization and improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an injection mold welding device to solve the problem that the existing injection mold lacks protection during repair welding, and most operators are directly exposed to the welding environment and are easily injured. Secondly, when repairing multiple sides, the flipping of the mold and the correction of the offset angle mostly rely on manual operation, which is inefficient, time-consuming and labor-intensive, and also dangerous.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, the synchronous motor is set up, which can drive the connecting rod to swing due to its clockwise and counterclockwise rotation. Since the connecting rod and the special-shaped rod are connected, it will also drive the sliding guide rod to move at a limited angle along the opening angle of the sliding groove on the left and right side walls of the welding chamber, so that the special-shaped rod drives the front sealing plate to open and close, and the lifting and lowering displacement of the sealing plate allows the welding work to be carried out in a relatively closed environment. The toxic gas and smoke generated by the welding mold of the laser repair welder are extracted through an exhaust fan set in the area connecting the filter and the middle cavity of the welding box, so that the gas and smoke will not escape into the external environment and cause harm to the operator.

[0019] The symmetrically arranged extension rods can drive the left and right clamps to move toward the middle area, so as to clamp the injection mold placed on the rotating module. After clamping, the two adjustment columns on each side can be driven to rotate by the adjustment motor, and the adjustment column and the cross bar are spirally installed. When the adjustment column rotates, the cross bar will be driven to move upward, so that the mold after clamping will move upward synchronously. After reaching the appropriate height, the servo motor set in the middle of the rear end of the U-shaped frame can drive the extension rod to rotate, and then drive the mold clamped by the clamps to flip over. After the mold is flipped over, the adjustment motor is controlled to work in reverse, and the flipped mold is placed on the rotating module, thereby completing the flipping of the mold. The entire process only requires the placement of the mold, and no excessive human involvement is required. It saves time and effort and is safer and faster.

[0020] The disc seat and disc column are provided to support the inner and outer gear discs. When the mold placement angle deviates, you only need to turn the turntable to drive the inner gear disc to start rotating. The inner and outer gear discs are installed in a meshing manner, which will drive the outer gear disc and the welding table fixed at the upper end to rotate together, thereby adjusting the overall deflection angle of the fixed injection mold. Compared with traditional manual movement, it will save time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figures 1 to 11 As shown, an embodiment of the present invention provides an injection mold welding device, including a welding box 1, an H-shaped frame 2 is provided at the rear end of the welding box 1, a clamping and flipping module 3 is provided at the upper end of the H-shaped frame 2, a balancing module 4 is provided in the middle of the upper end of the clamping and flipping module 3, a push-pull module 5 is provided on the left and right sides of the upper end of the H-shaped frame 2, a mounting platform 6 is provided on the front side of the upper end of the push-pull module 5, a reinforcement base plate 7 is provided in the middle of the upper end of the mounting platform 6, a rotation module 8 is provided in the middle of the upper end of the reinforcement base plate 7, a manual operation module 9 is provided on the inner side of the front end of the welding box 1, a laser repair welder 10 is provided in the middle of the upper end of the welding box 1, a sealing module 11 is provided on the rear side of the laser repair welder 10, a sealing motor 12 is provided on the right side of the sealing module 11, support legs 13 are provided on the left and right sides of the lower end of the welding box 1, and a filter 14 is provided on the upper left inside the welding box 1.

[0042] The horizontal diameter of the central cavity inside the welding box 1 is adapted to the horizontal diameter of the slot opened at the upper end of the H-shaped frame 2. The H-shaped frame 2 and the clamping and flipping module 3 are reinforced by four positioning bolts symmetrically distributed on the left and right. There are two groups of clamping and flipping modules 3 symmetrically distributed on the left and right. The contact end between the balancing module 4 and the clamping and flipping module 3 passes through the top of the clamping and flipping module 3 from below by bolts and extends to the inside of the balancing module 4 for reinforcement, so that the two form an integrated mounting structure. The push-pull module 5 and the H-shaped frame 2 are welded and fixed together, and there are two groups of push-pull modules 5 distributed in parallel laterally. The push-pull module 5 and the mounting platform 6 are connected and installed together by reinforcing bolts 505. The reinforced base plate 7 and the mounting platform 6 are inserted into the tightening mounting structure. Eight threaded adjustment struts are symmetrically installed on the four sides of the upper end of the reinforced base plate 7 to facilitate the rotation of the module 8. The top structure provides stable support after turning, the rotating module 8 and the reinforced base plate 7 are reinforced by annularly distributed fixing bolts, the manual operation module 9 and the welding box 1 are movably closed by a linkage structure, the laser repair welder 10 is fixedly installed in the middle of the upper end of the welding box 1, and the lower end structure of the laser repair welder 10 extends to the middle cavity inside the welding box 1, the sealing module 11 and the sealing motor 12 are reinforced with screws and the welding box 1, and the transmission end of the sealing motor 12 extends to the lower inner side of the front end of the sealing module 11, there are four support legs 13 symmetrically distributed, and two legs on each side are installed on the left and right sides of the lower end of the welding box 1 for support, the filter 14 is composed of activated carbon as a whole, and is filled and installed inside the welding box 1. Its filtering structure itself belongs to the existing public technology, so it will not be excessively described in this article.

[0043] During operation, the manual operation module 9 and the sealing module 11 are provided, and when the mounting table 6 drives the installed injection mold to start the repair welding work in the welding box 1, the welding area inside the welding box 1 is sealed front and back, so that the welding work is carried out in a relatively closed environment. The toxic gas and smoke generated by the laser repair welder 10 welding the mold are extracted by the exhaust fan provided in the area where the filter 14 is connected to the cavity in the middle of the welding box 1, so that the gas and smoke will not escape into the external environment and cause harm to the operator. At the same time, when the injection mold needs to be turned over, the sealing module 11 at the rear is opened, and the push-pull module 5 is started to work, driving the mounting table 6 to move backward from the welding box 1, thereby taking out the rotating module 8 and the injection mold installed above as a whole. The placement angle of the mold can be adjusted by the rotating module 8 to facilitate the subsequent clamping work. The clamping and flipping module 3 is set to start working, and moves from the left and right sides of the mold to the middle to clamp the mold. During the process of clamping the mold, the balancing module 4 will remain stable at the front end of the clamping structure of the clamping and flipping module 3. Then the adjusting motor 304 in the clamping and flipping module 3 will drive the adjusting column 303 to rotate, so that the cross bar 302 can be displaced longitudinally as a whole. After reaching the appropriate height, the servo motor located at the rear end of the U-shaped frame 305 on both sides starts working, driving the extension rod 306 to rotate, so that the clamped mold can be flipped. Then the above operation is reversed to reset the clamped mold and place it on the rotating module 8. Then the push-pull module 5 works in the opposite direction and pushes the mounting table 6 into the welding box 1 to continue the repair welding work. The flipping work of the entire mold only requires manual adjustment of the following placement angle. All other work can be completed automatically by machinery, which is more efficient and safer overall.

[0044] like Figures 7 to 9 As shown, in this embodiment, the welding box 1 includes a box body 101, a welding cavity 102, a side lower cavity 103 and a side upper cavity 104. The welding cavity 102 is opened in the middle of the inner side of the box body 101, the side lower cavity 103 is opened on the left and right sides of the welding cavity 102, and the side upper cavity 104 is opened above the side lower cavity 103.

[0045] There are two sliding grooves on the left and right side walls of the welding chamber 102, and the sliding grooves are symmetrically distributed. There are two side lower chambers 103 and side upper chambers 104 that are symmetrically distributed on the left and right. Batteries are provided at the bottom of the left and right side lower chambers 103. The left side upper chamber 104 is interconnected with the interior of the welding chamber 102, and an exhaust fan is installed inside the connecting channel. A manually pulled welding rod disk is installed inside the right side upper chamber 104 to facilitate manual operation when welding some precision molds.

[0046] During operation, through the set box 101, when the welding work starts, the mold to be welded can be placed on the mounting table 6, and then the push-pull module 5 pushes it as a whole into the welding chamber 102, and then the front sealing plate 901 in the manual operation module 9 and the sealing plate 112 in the sealing module 11 are used to close the front and rear ends of the welding chamber 102, so that the mold repair welding work is carried out in a sealed environment. At the same time, the smoke generated by welding will be extracted through the exhaust fan installed inside the connecting channel between the left side upper chamber 104 and the welding chamber 102, allowing the smoke to enter the filter 14 for filtration and then discharged. At the same time, the synchronous motor 907 arranged inside the side lower chamber 103 can drive the front sealing plate 901 in the manual operation module 9 to open and close, which is more convenient for subsequent cleaning of the inside of the welding chamber 102. The manually pulled welding rod disc installed inside the right side upper chamber 104 is convenient for manual operation when welding some precision molds.

[0047] like Figures 1 to 3 As shown, in this embodiment, the H-shaped frame 2 includes a frame body 201, a support block 202, a ball bearing 203 and a positioning hole 204. The support block 202 is provided on the inner side of the upper end of the frame body 201, and the ball bearing 203 is laterally distributed on the upper end of the support block 202. Positioning holes 204 are provided on the left and right sides of the upper end of the H-shaped frame 2.

[0048] The frame 201 and the support block 202 are of an integrated structure, and the height of the spacing area between the support block 202 and the middle horizontal plate of the frame 201 is just adapted to the longitudinal height of the push-pull module 5. Secondly, the height from the upper surface of the support block 202 to the top position of the frame 201 is higher than the overall height of the mounting platform 6 by the height of the ball 203 protruding from the upper surface of the support block 202. The ball 203 is embedded and installed on the inner side of the upper end of the support block 202, and the ball 203 is symmetrically arranged in the longitudinal direction.

[0049] During operation, the push-pull module 5 can be installed parallel to the left and right sides of the upper end of the middle horizontal plate through the set frame 201, and then the push-pull module 5 and the mounting platform 6 are reinforced together with the reinforcement bolts 505. During subsequent operation, the push-pull module 5 can drive the mounting platform 6 to move forward and backward along the upper end of the support block 202. At the same time, the set ball 203 can reduce the difficulty of the displacement of the mounting platform 6, and can also prevent the mounting platform 6 and the support block 202 from wear, thereby increasing its service life.

[0050] like Figures 2 to 4As shown, in this embodiment, the clamping and flipping module 3 includes a rectangular frame 301, a cross bar 302, an adjusting column 303, an adjusting motor 304, a U-shaped frame 305, an extension rod 306 and a clamping claw 307. A cross bar 302 is provided in the middle of the inner side of the rectangular frame 301, and adjusting columns 303 are symmetrically distributed on the left and right sides of the rectangular frame 301. The upper end of the adjusting column 303 is provided with an adjusting motor 304, a U-shaped frame 305 is provided on the left side of the outer end of the cross bar 302, an extension rod 306 is provided in the middle of the inner side of the U-shaped frame 305, and a clamping claw 307 is provided at the front end of the extension rod 306; the balancing module 4 includes a cross frame 401, a suspension rod 402, a displacement motor 403 and a pin 404, a suspension rod 402 is provided on the left and right sides of the lower end of the cross frame 401, a displacement motor 403 is provided on the left and right sides of the outer end of the cross frame 401, and a pin 404 is provided on the outer side of the lower end of the suspension rod 402.

[0051] The rectangular frame 301 is an integrated structure. The overall length of the crossbar 302 is slightly smaller than the diameter of the internal cavity of the rectangular frame 301. The left and right sides of the crossbar 302 just do not touch the inner wall of the rectangular frame 301. There are two symmetrically distributed adjustment columns 303. The two adjustment columns 303 pass through the inner wall of the top of the rectangular frame 301 and the interior of the crossbar 302 from the top of the rectangular frame 301 downwards, and continue to extend to the inner wall of the lower end of the rectangular frame 301. Anti-friction bearings are provided at the upper and lower ends of the adjustment columns 303 and the contact positions with the rectangular frame 301. The adjustment motor 304 is symmetrical. There are four distributed, two installed on each side, and the four symmetrically distributed regulating motors 304 are synchronously controlled by a control device. The driving end of the regulating motor 304 and the top of the regulating column 303 are mutually clamped and spliced ​​into an integrated structure, which is convenient for subsequent power transmission. The U-shaped frame 305 and the cross bar 302 are reinforced by screws. The extension rod 306 is installed in the middle of the inner side of the U-shaped frame 305, and the front end of the extension rod 306 passes through the interior of the U-shaped frame 305 and the cross bar 302 and extends to the outside. The connection between the extension rod 306 and the U-shaped frame 305 and the cross bar 302 is very convenient. An anti-friction bearing is installed at the contact end position. At the same time, a clamping claw 307 is installed at the front end of the extension rod 306. The extension rod 306 is driven by hydraulic pressure. Its structure itself belongs to the existing well-known technology. Therefore, it will not be excessively described in this article. A servo motor is installed in the middle of the rear end of the U-shaped frame 305. The driving end of the servo motor is assembled with the rear end of the extension rod 306 by screws to control the rotation of the extension rod 306 as a whole. The clamping height of the clamping claw 307 itself can be freely adjusted according to the actual height of the mold; the horizontal frame 401 is an inverted U-shaped one The structure is a rectangular groove, and the inner side of the lower end of the horizontal frame 401 is provided with a rectangular groove, which is adapted to the top of the suspension rod 402. There are two suspension rods 402 symmetrically distributed on the left and right, and there are two displacement motors 403 symmetrically distributed on the left and right. Among them, the driving ends of the left and right displacement motors 403 are forward through the interior of the upper ends of the left and right suspension rods 402 and continue to extend outward to the protrusion in the middle of the lower end of the horizontal frame 401. The driving ends of the left and right displacement motors 403 are not connected, and the contact ends with the protrusions are installed with anti-friction bearings. The bayonet 404 is threadedly installed on the outer side of the lower end of the suspension rod 402

[0052] During operation, the symmetrically arranged extension rods 306 can drive the left and right clamps 307 to move toward the middle area to clamp the injection mold placed on the rotating module 8. After clamping is completed, the adjustment motor 304 can be used to drive the two adjustment columns 303 on each side to rotate, and the adjustment columns 303 and the cross bar 302 are in a spiral installation structure. When the adjustment columns 303 rotate, the cross bar 302 will be driven to move upward, so that the mold after clamping is completed will move upward synchronously. After reaching the appropriate height, the servo motor set in the middle of the rear end of the U-shaped frame 305 can drive the extension rod 306 to rotate, and then drive the mold clamped by the clamps 307 to turn over. Wait until the mold is turned over. After completion, the control and adjustment motor 304 works in the reverse direction and places the turned-over mold on the rotating module 8, thereby completing the flipping of the mold. The entire process does not require excessive human involvement, which not only saves time and effort, but is also safer and faster. Secondly, when the two extension rods 306 drive the left and right clamps 307 to clamp the injection mold, the two suspension rods 402 that are connected to the front end of the extension rod 306 will also be synchronously displaced toward the middle under the drive of the left and right displacement motors 403. The main purpose is to allow the extension rod 306 to support the force on the front end of the extension rod 306 when clamping, to ensure the safety of the extension rod 306 during operation, to prevent the extension rod 306 from bending and deforming due to excessive force, and to play a protective role.

[0053] like Figures 3 to 5 As shown, in this embodiment, the push-pull module 5 includes a push-pull frame 501, a displacement seat 502, a push-pull motor 503, a screw 504, and a reinforcement bolt 505.

[0054] The sliding frame 501 is an integrated rectangular structure, and the displacement seat 502 is installed at the upper end of the sliding frame 501 in a sliding and clamping manner. The push-pull motor 503 is reinforced by a screw pin in the middle of the rear end of the sliding frame 501, and the transmission end of the push-pull motor 503 passes through the outer wall of the rear end of the sliding frame 501 and is connected to the screw 504 to form an integrated structure. The front end of the screw 504 passes through the interior of the displacement seat 502 and extends to the inner wall of the front end of the sliding frame 501. The contact ends of the two are provided with anti-wear bearings, and the reinforcement bolts 505 are symmetrically distributed on the upper end of the displacement seat 502. The reinforcement bolts 505 pass through the displacement seat 502 from the bottom of the displacement seat 502 and extend to the upper outside.

[0055] During operation, the displacement seat 502 is reinforced and installed together with the rear side of the lower end of the mounting table 6 through the provided reinforcement bolts 505, and then the push-pull motor 503 starts to work, driving the screw 504 to start rotating, and the screw 504 and the displacement seat 502 are spirally installed, so that the displacement seat 502 can move forward and backward along the push-pull frame 501 according to the rotation angle of the screw 504, thereby driving the mounting table 6 to move forward and backward, realizing the taking of the mounting table 6 inside and outside the welding box 1.

[0056] like Figures 3 to 6 As shown, in this embodiment, the rotating module 8 includes a disc seat 801, a disc column 802, an inner gear disc 803, a turntable 804, a rotating bearing 805, an outer gear disc 806 and a welding platform 807. A disc column 802 is provided in the middle of the upper end of the disc seat 801, an inner gear disc 803 is provided at the upper end of the disc seat 801, a turntable 804 is provided at the outer end of the inner gear disc 803, a rotating bearing 805 is sleeved on the upper end of the disc column 802, an outer gear disc 806 is provided on the inner teeth of the upper end of the inner gear disc 803, and a welding platform 807 is provided at the upper end of the outer gear disc 806.

[0057] The disc seat 801 and the disc column 802 are an integrated structure. At the same time, the outer ring of the upper end of the disc seat 801 extends to the inner side of the lower end of the inner gear disc 803, and the inner side of the outer ring of the upper end of the disc seat 801 is annularly provided with a ball, which contacts the lower end of the inner gear disc 803. The upper end of the disc column 802 and the rotating bearing 805 are mutually socketed, and the outer end of the inner gear disc 803 forms an integrated structure with the turntable 804 through annularly distributed round rods. The inner diameter of the inner gear disc 803 is adapted to the outer diameter of the lower end of the outer gear disc 806, and the two are meshed and assembled together. A circular notch is provided in the middle of the lower end of the outer gear disc 806, and the overall diameter of the circular notch is adapted to the overall diameter of the rotating bearing 805. An annular reinforcement hole is provided on the outer side of the upper end of the outer gear disc 806 to facilitate reinforcement after installing the welding table 807.

[0058] During operation, the inner gear disc 803 and the outer gear disc 806 are supported by the provided disc seat 801 and disc column 802. Later, when it is necessary to adjust the overall angle of the injection mold installed above the welding table 807, it is only necessary to rotate the turntable 804 to drive the inner gear disc 803 to start rotating. The inner gear disc 803 and the outer gear disc 806 are installed in a meshing manner with each other, which will drive the outer gear disc 806 and the welding table 807 fixed at the upper end to rotate together, thereby adjusting the overall angle of the fixed injection mold. The entire rotation angle adjustment is time-saving and labor-saving, and does not require manual movement.

[0059] like Figures 7 to 10As shown, in this embodiment, the manual operation module 9 includes a front cover plate 901, a shooting display screen 902, a glove interface 903, a special-shaped rod 904, a sliding guide rod 905, a connecting rod 906 and a synchronous motor 907. A shooting display screen 902 is provided on the upper back of the front cover plate 901, a glove interface 903 is provided on the left and right sides behind the shooting display screen 902, a special-shaped rod 904 is provided on the left and right sides of the shooting display screen 902, a sliding guide rod 905 is provided on the right side of the upper end of the special-shaped rod 904, a connecting rod 906 is provided below the sliding guide rod 905, and a synchronous motor 907 is provided on the right side of the connecting rod 906.

[0060] A shooting display screen 902 is embedded in the upper inner side of the front end of the front cover 901. The shooting display screen 902 consists of a screen and a rear camera. Two glove interfaces 903 are symmetrically provided to facilitate operation during subsequent precision mold welding. Two special-shaped rods 904 are symmetrically distributed on the left and right, and the special-shaped rods 904 and the front cover 901 are reinforced together by screws. The sliding guide rod 905 and the special-shaped rod 904 are installed in a sleeve-like manner. The sliding guide rod 905 is embedded in two sliding grooves on the left and right side walls of the welding cavity 102. The connecting rod 906 and the special-shaped rod 904 are installed in a sleeve-like manner, and the contact end of the connecting rod 906 and the synchronous motor 907 is fixedly installed.

[0061] During operation, the synchronous motor 907 is set to work clockwise, driving the connecting rod 906 to swing backward. While the connecting rod 906 is swinging, since the connecting rod 906 and the special-shaped rod 904 are installed in a socketed manner, it will drive the sliding guide rod 905 to move at a limited angle along the opening angle of the sliding groove on the left and right side walls of the welding chamber 102, thereby driving the special-shaped rod 904 to pull the front sealing plate 901 to move backward. In combination with the sealing plate 112, the front and rear ends of the welding chamber 102 opened in the welding box 1 can be closed. Subsequently, the synchronous motor 907 can also be controlled to rotate counterclockwise, and the above-mentioned closing operation is reversed to open the front sealing plate 901, so that the front end of the welding chamber 102 inside the welding box 1 is opened, which is convenient for rapid cleaning.

[0062] like Figures 7 to 11 As shown, in this embodiment, the sealing module 11 includes a sealing seat 111, a sealing plate 112, a lifting groove 113, a gear 114 and a protruding plate 115. A sealing plate 112 is provided on the inner side of the upper end of the sealing seat 111, and lifting grooves 113 are provided on the left and right sides of the front end of the sealing plate 112. A gear 114 is provided below the front side of the lifting groove 113, and a protruding plate 115 is provided on the front side of the top end of the sealing plate 112.

[0063] An inverted L-shaped notch is provided inside the sealing seat 111, and the lower end of the sealing plate 112 is installed on the rear side of the inverted L-shaped notch, while gears 114 are symmetrically installed on the left and right sides of the front side of the inverted L-shaped notch. The symmetrically installed gears 114 are both penetrated by the transmission end of the sealing motor 12, and the two gears 114 are fixed at the position where they contact the transmission end of the sealing motor 12. The lifting grooves 113 are symmetrically provided on the left and right sides of the front end of the sealing plate 112, and the lifting grooves 113 and the gears 114 are engaged with each other. The convex plate 115 and the sealing plate 112 are an integrated structure. The length and width of the combination of the convex plate 115 and the sealing plate 112 are adapted to the size of the notch provided at the upper end of the sealing seat 111.

[0064] During operation, the gear 114 is driven by the sealing motor 12 to rotate, and the gear 114 and the lifting groove 113 are installed in a mutually meshing manner, thereby driving the sealing plate 112 to rise and fall along the groove opened at the top of the sealing seat 111, and the rear end of the welding chamber 102 inside the welding box 1 can be quickly closed and opened.

[0065] The working principle of the technical solution provided by the present invention is as follows: through the provided manual operation module 9 and the sealing module 11, when the mounting table 6 drives the installed injection mold to start the repair welding work in the welding box 1, the welding area inside the welding box 1 is sealed front and back, so that the welding work is carried out in a relatively closed environment. The toxic gas and smoke generated by the laser repair welder 10 welding the mold are extracted by the exhaust fan provided in the area connecting the filter 14 and the middle cavity of the welding box 1, so that the gas and smoke will not escape into the external environment and cause harm to the operator. At the same time, when it is necessary to turn the injection mold over, the rear sealing module 11 is opened, and the push-pull module 5 is started to work, driving the mounting table 6 to move backward from the welding box 1, thereby taking out the rotating module 8 and the injection mold installed above as a whole. The placement angle of the mold can be adjusted by the rotating module 8 to facilitate the subsequent clamping work. The extension rod 306 is set to drive the left and right clamping claws 307 to move toward the middle area to clamp the injection mold placed on the rotating module 8. After clamping is completed, the adjustment motor 304 is set to drive the two adjustment columns 303 on each side to rotate, and the adjustment column 303 and the cross bar 302 are spirally installed. When the adjustment column 303 rotates, it will drive the cross bar 302 to move upward, so that the mold after clamping is completed will move upward synchronously. After reaching the appropriate height, the servo motor set in the middle of the rear end of the U-shaped frame 305 can drive the extension rod 306 to rotate, and then drive the mold clamped by the clamping claws 307 to turn over. After the mold is turned over, the adjustment motor 304 is controlled to work in the opposite direction to place the turned-over mold on the rotating module 8, thereby completing the mold flipping work. The entire process does not require excessive human participation, which saves time and effort and is safer and faster.
