The plastic components are usually processed by injection molding using upper and lower molds.

[0003] Currently, when automotive parts are processed using injection molding with a mold-closing method, a lower mold is usually installed on a fixed platform, and a drive mechanism is used to drive the upper mold to close the mold before injection molding. Due to various factors, it is difficult to carry out mass production, resulting in low processing efficiency.

[0010] Preferably, the cylinder extension end slides through the outer surface of the bracket and extends downwards, and a thermocouple is fixedly installed on the cylinder extension end, with the thermocouple and the top center of the tray corresponding to each other.

[0011] Preferably, the hydraulic mechanism includes a hydraulic oil tank, an oil pipe is fixedly connected to one outer surface of the hydraulic oil tank, an oil pump is provided at one end of the oil pipe, and the oil pipe and the input end of the oil pump are connected.

[0014] Preferably, a limiting ring is fixedly connected between the inner walls of the movable cavity near the bottom, the piston is disposed on the top of the limiting ring, a top seal is fixedly connected between the inner walls of the movable cavity near the top, and the outer surface of the push rod slides through the outer surface of the top seal and extends upwards.

An oil inlet groove is provided on one side of the inner wall of the movable cavity near the bottom, and an oil outlet groove is provided on the upper part of the other side of the inner wall of the movable cavity. A connecting groove is provided inside the second mounting shell, and the adjacent oil outlet groove and oil inlet groove are respectively connected to the two ends of the connecting groove.

[0015] A method for using a multi-station mold base for processing automotive parts includes the following steps:

[0016] S1. When processing automotive parts through injection molds, multiple lower molds are placed on the tray of this device by a robotic arm. Then, the first motor is started to drive the drive gear to rotate, thereby driving the adjacent gear disk to rotate. When the gear disk rotates, the first rotating column and rotating hole under all the connecting rods rotate and shift at the same time. At this time, the second rotating column and slider at the top of the connecting rod rotate and drag the slider. The slider is restricted by the guide groove at the top of the tray. Therefore, all the sliders drive all the clamping rods to move towards the center at the same time, thereby clamping and fixing the lower molds at the top of the tray and placing them in the center of the tray.

[0017] S2. After injection molding is completed, the mold is separated. Then, the second motor is started to drive the connecting shaft to rotate. After the connecting shaft rotates, it drives the rotating blocks inside all the rotating seats to rotate forward, thereby driving the L-shaped bracket to flip up to the fixed lower mold. At this time, the cylinder is started to drive the thermocouple to descend, thereby contacting the automotive part disc embryo inside the lower mold to detect the temperature of the workpiece embryo. When the temperature drops to the expected range, it can be taken out. Workpiece embryos at all stations can be detected simultaneously.

[0018] S3. After the inspection is completed, the hydraulic oil in the hydraulic oil tank is drawn out by starting the oil pump and the oil pipe and sent into the connecting groove inside the second outer mounting shell through the second connecting pipe. At this time, when the hydraulic oil enters the movable cavity of the first mounting shell through the oil inlet groove, it will generate an upward squeezing force, which will push the piston and the push rod to rise slowly. When the piston rises above the oil outlet groove, the hydraulic oil enters the connecting groove through the oil outlet groove, and then enters the oil inlet groove of the next first mounting shell, thus sequentially pushing all the pistons upward in sequence. Together with the push rod, it plays the role of pushing out the workpiece embryo inside the lower mold, realizing batch feeding.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In use, the first motor is started and the drive gear drives the adjacent gear disks to rotate. When the gear disks rotate, the connecting rod, the first rotating column and the second rotating column drag the slider. The slider is restricted by the guide groove on the top of the tray. Therefore, all sliders drive all clamping rods to move towards the center at the same time, thereby clamping and fixing the lower mold on the top of the tray and placing it in the center of the tray. This design can increase the number of fastening mechanisms according to actual needs to achieve the function of multi-station synchronous fixing of the lower mold of automotive parts. It also has a built-in position correction function. When used with the corresponding upper mold, it can greatly improve the processing efficiency of automotive parts.

[0021] 2. In use, the second motor is started to drive the connecting shaft to rotate. After the connecting shaft rotates, it drives all the rotating blocks inside the rotating seats to rotate forward, thereby causing the L-shaped bracket to flip up to the top of the fixed lower mold. At this time, the cylinder is started to drive the thermocouple to descend, thereby contacting the automotive part disc embryo inside the lower mold to detect the temperature of the workpiece embryo. When the temperature drops to the expected range, it can be taken out. Workpiece embryos at all stations can be detected simultaneously, with high detection efficiency, avoiding the problem of quality degradation after the embryo is taken out in a state of not being completely cooled.

[0022] 3. During use, the hydraulic oil in the hydraulic oil tank is drawn out by starting the oil pump and the oil pipe and sent into the connecting groove inside the second outer mounting shell through the second connecting pipe. At this time, when the hydraulic oil enters the movable cavity of the first mounting shell through the oil inlet groove, it will generate an upward squeezing force, which will push the piston and the push rod to rise slowly. When the piston rises above the oil outlet groove, the hydraulic oil enters the connecting groove through the oil outlet groove, and then enters the oil inlet groove of the next first mounting shell, thus sequentially pushing all the pistons upward in turn. Together with the push rod, it plays the role of pushing out the workpiece embryo inside the lower mold, realizing batch feeding and improving the overall processing efficiency of automotive parts.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1-10 As shown: A multi-station mold frame for processing automotive parts includes a base frame 1, an outer frame 11 fixedly connected to the top edge of the base frame 1, a top plate 14 fixedly connected between the inner surface walls of the outer frame 11 near the top, a mounting plate 12 fixedly connected between the inner surface walls of the outer frame 11 below the top plate 14, a controller 13 mounted on the front surface of the outer frame 11, multiple fastening mechanisms 3 equidistantly arranged on the top of the mounting plate 12, a detection mechanism 4 mounted on the rear surface of the outer frame 11, a lifting mechanism 6 mounted at the top center of the base frame 1, a hydraulic mechanism 5 mounted on the top of the base frame 1 in front of the lifting mechanism 6, and a fixed outer surface on one side of the outer frame 11. A motor base 2 is fixedly connected, and a first motor 21 is mounted on the top of the motor base 2. A drive gear 22 is fixedly connected to the output end of the first motor 21. Multiple fastening mechanisms 3 each include a tray 301. The tray 301 is fixedly installed inside the top plate 14. A first connecting ring 303 is fixedly connected to the bottom of the tray 301 near the edge. A bearing 304 is fixedly connected to the outer surface of the first connecting ring 303. A second connecting ring 305 is fixedly connected to the outer surface of the bearing 304. A gear disk 306 is fixedly connected to the bottom of the second connecting ring 305. Multiple gear disks 306 are meshed with each other, and one of the gear disks 306 is meshed with the drive gear 22.

[0037] like Figure 1 , Figure 2 , Figures 4-6 As shown, the top of the tray 301 has multiple guide grooves 302 equidistantly spaced, and a slider 311 is slidably disposed inside the guide grooves 302. A clamping rod 312 is symmetrically fixedly connected to the top of the slider 311. The top of the gear disk 306 has multiple rotating holes 307 equidistantly spaced, and a first rotating column 309 is rotatably connected inside the rotating hole 307. A connecting rod 308 is fixedly connected to the top of the first rotating column 309. A second rotating column 310 is fixedly connected to the top of the connecting rod 308 at a position away from the first rotating column 309. The second rotating column 310 and the bottom of the slider 311 are rotatably connected. When the gear disk 306 rotates, the first rotating column 309 below all the connecting rods 308 and the rotating column 307 rotate. Simultaneously, the moving hole 307 rotates and shifts. At this time, the second rotating column 310 and the slider 311 at the top of the connecting rod 308 rotate and drag the slider 311. The slider 311 is restricted by the guide groove 302 at the top of the tray 301. Therefore, all sliders 311 simultaneously drive all clamping rods 312 to move towards the center, thereby clamping and fixing the lower mold at the top of the tray 301 and placing it in the center position of the tray 301. This design can increase the number of fastening mechanisms 3 according to actual needs to achieve the function of multi-station synchronous fixing of the lower mold of automotive parts, and has a built-in position correction function. When used with the corresponding upper mold, it can greatly improve the processing efficiency of automotive parts.

[0038] like Figure 1 , Figure 2 and Figure 7 As shown, the detection mechanism 4 includes a second motor 401 and multiple rotating seats 403. The multiple rotating seats 403 are equidistantly fixedly connected to the rear surface of the outer frame 11. The rotating seats 403 and the tray 301 are positioned correspondingly. The second motor 401 is fixedly installed on the rear surface of the outer frame 11 near one edge. The output end of the second motor 401 is fixedly connected to a connecting shaft 402. Rotating blocks 404 are rotatably connected between the inner walls of the rotating seats 403. The number of rotating seats 403 is set according to the number of fastening mechanisms 3. When the second motor 401 is started to drive the connecting shaft 402 to rotate, the rotating blocks 404 inside all rotating seats 403 can be rotated synchronously.

[0039] like Figure 1 , Figure 2 and Figure 7 As shown, the outer surface of the connecting shaft 402 slides through the outer surface of multiple rotating seats 403 and is connected to multiple rotating blocks 404. A bracket 405 is fixedly connected to the top of the rotating block 404. The bracket 405 is L-shaped. A cylinder 406 is fixedly installed on the top of the bracket 405 at a position away from the rotating block 404. When the second motor 401 drives the connecting shaft 402 to rotate, causing all the rotating blocks 404 to flip to the rear, it can drive all the brackets 405 to rotate to the rear of the equipment, so that the injection molding process can be carried out normally. After all the brackets 405 follow the rotating blocks 404 to rotate to the front, they will drive the cylinder 406 to move to the top of the tray 301.

[0040] like Figure 1 , Figure 2 and Figure 7 As shown, the telescopic end of cylinder 406 slides through the outer surface of bracket 405 and extends downwards. A thermocouple 407 is fixedly installed on the telescopic end of cylinder 406. The thermocouple 407 and the top center of tray 301 are positioned corresponding to each other. When cylinder 406 moves to the position directly above tray 301, cylinder 406 is activated to drive thermocouple 407 to descend, thereby contacting the automotive part tray embryo inside the lower mold to detect the temperature of the workpiece embryo. When the temperature drops to the expected range, it can be removed. Workpiece embryos at all stations can be detected simultaneously, resulting in high detection efficiency and avoiding the problem of quality degradation after the embryo is removed in a state of incomplete cooling.

[0041] like Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, the hydraulic mechanism 5 includes a hydraulic oil tank 501. An oil pipe 502 is fixedly connected to one outer surface of the hydraulic oil tank 501. An oil pump 504 is provided at one end of the oil pipe 502, and the oil pipe 502 and the input end of the oil pump 504 are connected. By starting the oil pump 504, the hydraulic oil inside the hydraulic oil tank 501 can be drawn out through the oil pipe 502.

[0042] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the output end of the oil pump 504 is fixedly connected to a second connecting pipe 505. A first solenoid valve 506 is provided on the outside of the second connecting pipe 505. The other side of the outer surface of the hydraulic oil tank 501 is fixedly connected to a first connecting pipe 503. A second solenoid valve 507 is provided on the outside of the first connecting pipe 503. After the oil pump 504 draws out the hydraulic oil from the hydraulic oil tank 501, it can be transported through the second connecting pipe 505 to the connecting groove 610 inside one of the second mounting shells 609. By setting the first connecting pipe 503 in conjunction with the second connecting pipe 505, the connecting groove 610, the oil inlet groove 607 and the oil outlet groove 608 inside the first mounting shell 601 and the second mounting shell 609 can form a connected oil circuit. After the oil circuit is filled with hydraulic oil, the oil circuit connected to the hydraulic oil tank 501 can be switched to a closed circuit state by activating the first solenoid valve 506 and the second solenoid valve 507.

[0043] like Figure 8 and Figure 10 As shown, the lifting mechanism 6 includes multiple first mounting shells 601 and multiple second mounting shells 609. The first mounting shells 601 and the second mounting shells 609 are welded and fixed in an alternating sequence. The first mounting shell 601 has a movable cavity 602 inside. A piston 605 is slidably connected inside the movable cavity 602. A push rod 606 is fixedly connected to the top of the piston 605. The piston 605 mainly divides the movable cavity 602 inside the first mounting shell 601 into upper and lower parts. When the piston 605 moves upward, it pushes the push rod 606 to move above the first mounting shell 601 and into the demolding hole of the lower mold, thereby ejecting the internal automotive part embryo and facilitating unloading.

[0044] like Figure 8 and Figure 10As shown, a limiting ring 603 is fixedly connected between the inner walls of the movable cavity 602 near the bottom. The piston 605 is located on top of the limiting ring 603. A top seal 604 is fixedly connected between the inner walls of the movable cavity 602 near the top. The outer surface of the push rod 606 slides through the outer surface of the top seal 604 and extends upwards. The outer surface of the push rod 606 slides through the outer surfaces of the mounting plate 12, gear disk 306, and tray 301 in sequence. An oil inlet groove 607 is provided on one side of the inner wall of the movable cavity 602 near the bottom, and an oil outlet groove 608 is provided on the upper part of the other side of the inner wall of the movable cavity 602. A connecting groove 610 is provided inside the second mounting shell 609. The adjacent oil outlet groove 608 and oil inlet groove 607 are connected to the two ends of the connecting groove 610. The limiting ring 603 and the top seal 604 are mainly used to control the piston. 605 is used for limiting. The connecting groove 610 inside the second mounting shell 609 is Z-shaped. It is mainly used to connect the oil outlet groove 608 at the high position and the oil inlet groove 607 at the low position of the adjacent first mounting shell 601. When the hydraulic oil enters the movable cavity 602 of the first mounting shell 601 through the oil inlet groove 607, it will generate an upward squeezing force, thereby pushing the piston 605 and the push rod 606 to rise slowly. When the piston 605 rises above the oil outlet groove 608, the hydraulic oil enters the connecting groove 610 through the oil outlet groove 608, and then enters the oil inlet groove 607 of the next first mounting shell 601, thereby sequentially pushing all the pistons 605 upward in sequence. Together with the push rod 606, it plays the role of pushing out the workpiece embryo inside the lower mold, realizing batch feeding and improving the overall processing efficiency of automotive parts. Press the push rod 606 when returning oil.

[0045] In this invention, when processing automotive parts using injection molds, a robotic arm places multiple lower molds onto the tray 301 of this device. Then, the first motor 21 is activated, driving the drive gear 22 to rotate, which in turn drives the adjacent gear disk 306 to rotate. When the gear disk 306 rotates, the first rotating column 309 and rotating hole 307 below all connecting rods 308 simultaneously rotate and shift. At this time, the second rotating column 310 and slider 311 at the top of the connecting rods 308 rotate and drag the slider 311. The slider 311 is restricted by the guide groove 302 at the top of the tray 301, therefore all sliders 311 simultaneously drive all clamps... Rod 312 moves synchronously towards the center, clamping and fixing the lower mold on top of tray 301, placing it at the center of tray 301. This design can increase the number of fastening mechanisms 3 according to actual needs, thus achieving multi-station synchronous fixing of automotive parts lower molds, and has a built-in position correction function. Combined with the corresponding upper mold, it can greatly improve the processing efficiency of automotive parts. Afterwards, the upper mold and the fixed lower mold are driven by the external drive mechanism to close the mold, and injection molding can be performed. After injection molding, the mold is separated, and then the second motor 401 is started to drive the connecting shaft 402 to rotate. After the connecting shaft 402 rotates, it drives all rotating seats 403. The internal rotating block 404 rotates forward, causing the L-shaped bracket 405 to flip above the fixed lower mold. At this time, the starting cylinder 406 drives the thermocouple 407 to descend, thus contacting the automotive part disc embryo inside the lower mold to detect the temperature of the workpiece embryo. When the temperature drops to the expected range, it can be removed. Workpiece embryos at all stations can be detected simultaneously, resulting in high detection efficiency and avoiding the problem of quality degradation after the embryo is removed when it is not fully cooled. After the detection is completed, the hydraulic pump 504, in conjunction with the oil pipe 502, draws out the hydraulic oil from the hydraulic oil tank 501 and sends it to the outer side through the second connecting pipe 505. Inside the connecting groove 610 of the second mounting housing 609, when hydraulic oil enters the movable cavity 602 of the first mounting housing 601 through the oil inlet groove 607, it generates an upward squeezing force, which pushes the piston 605 and the push rod 606 to rise slowly. When the piston 605 rises above the oil outlet groove 608, the hydraulic oil enters the connecting groove 610 through the oil outlet groove 608, and then enters the oil inlet groove 607 of the next first mounting housing 601, thus sequentially pushing all the pistons 605 upward in sequence. Together with the push rod 606, they play the role of pushing out the workpiece embryo inside the lower mold, realizing batch feeding and improving the overall processing efficiency of automotive parts.

7. A method of using a multi-station mold base for processing automotive parts, characterized in that, The multi-station mold base for processing automotive parts as described in claim 6 includes the following steps: S1. When processing automotive parts through injection molds, multiple lower molds are placed on the tray (301) of this device by a robotic arm. Then, the first motor (21) is started to drive the drive gear (22) to rotate, thereby driving the adjacent gear disk (306) to rotate. When the gear disk (306) rotates, the first rotating column (309) and rotating hole (307) under all connecting rods (308) rotate and shift at the same time. At this time, the second rotating column (310) and slider (311) at the top of the connecting rod (308) rotate and drag the slider (311). The slider (311) is restricted by the guide groove (302) at the top of the tray (301). Therefore, all sliders (311) simultaneously drive all clamping rods (312) to move towards the middle in sync, thereby clamping and fixing the lower mold at the top of the tray (301) and placing it in the center of the tray (301). S2. After injection molding is completed, the mold is separated. Then, the second motor (401) is started to drive the connecting shaft (402) to rotate. After the connecting shaft (402) rotates, it drives the rotating blocks (404) inside all rotating seats (403) to rotate forward, thereby driving the L-shaped bracket (405) to flip up to the top of the fixed lower mold. At this time, the cylinder (406) is started to drive the thermocouple (407) to descend, thereby contacting the automotive part disc embryo inside the lower mold to detect the temperature of the workpiece embryo. When the temperature drops to the expected range, it can be taken out. The workpiece embryos of all stations can be detected simultaneously. S3. After the test is completed, the hydraulic oil inside the hydraulic oil tank (501) is extracted by starting the oil pump (504) and the oil pipe (502) and sent into the connecting groove (610) inside the second outer mounting shell (609) through the second connecting pipe (505). At this time, when the hydraulic oil enters the active cavity (602) of the first mounting shell (601) through the oil inlet groove (607), it will generate an upward squeezing force, thereby pushing the piston (605) and the push rod (606) to rise slowly. When the piston (605) rises above the oil outlet groove (608), the hydraulic oil enters the connecting groove (610) through the oil outlet groove (608) and then enters the oil inlet groove (607) of the next first mounting shell (601), thereby sequentially pushing all the pistons (605) upward in sequence, and working with the push rod (606) to push out the workpiece embryo inside the lower mold, realizing batch feeding.
