Description

Technical Field

[0001] The present invention belongs to the technical field of soft cushion assembly processing, and specifically relates to a rubber injection molding machine for soft cushion assemblies. Background Art

[0002] The engine soft cushion assembly is a buffer and shock-absorbing component during the installation and connection of the engine. During the processing and production of the soft cushion assembly, injection molding is required using an injection molding machine. When the soft cushion assembly is injection-molded, the already injection-molded soft cushion assembly is taken out from the injection mold. After demolding, residual rubber chips often easily adhere to the lower mold parting surface of the mold. Part of these residual rubber chips is electrostatically adsorbed on the parting surface of the lower mold, and another part adheres to the parting surface. If the rubber chips on the parting surface are not removed, it will prevent the mold from closing completely, resulting in the phenomenon that rubber easily overflows from the mold gap during the injection molding process. The traditional solution is to directly scrape with a scraper, but this method is likely to leave scratches and damages on the parting surface of the mold, and it is also not easy to completely remove the adhered rubber chips.

[0003] Therefore, a rubber injection molding machine for soft cushion assemblies is proposed to solve the above problems. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a rubber injection molding machine for soft cushion assemblies.

[0005] To achieve the above object, the present invention provides the following technical solution: A rubber injection molding machine for soft cushion assemblies, comprising a workbench, an injection mechanism, a moving frame, a lower mold, an upgrading frame, an upper mold, a transverse moving frame, and a cleaning mechanism;

[0006] The injection mechanism is arranged on the workbench. The moving frame is slidably installed on the workbench through an electromagnetic slide rail. The lower mold is slidably installed on the moving frame and is driven by a lead screw motor. The upper mold is arranged below the upgrading frame. The lower mold is arranged below in the moving frame. The transverse moving frame is slidably installed on the workbench through an electromagnetic slide rail. The cleaning mechanism is slidably installed on the transverse moving frame and is driven by a lead screw motor;

[0007] The cleaning mechanism includes a movable frame. Two mounting blocks are respectively connected to the front and rear of one side of the movable frame. An air cylinder is fixedly installed in the mounting block. A piston rod is sleeved in the air cylinder. An air hole is opened in the piston rod. One end of the air hole extends to the outside of the air cylinder and a fixed block is fixedly sleeved outside. A guide wheel is movably installed in the mounting block. An arc-shaped block one is connected to one side in the mounting block. The number of the fixed blocks is two. A copper wire is connected to one side of each of the two fixed blocks. The copper wire can pass through the arc-shaped block one and the guide wheel.

[0008] Preferably, a first spring is sleeved outside the piston rod. One end of the first spring is connected to the piston rod, and the other end of the first spring is connected to a pressing plate. The other end of the pressing plate abuts against a pressure sensing element installed in the air cylinder.

[0009] Preferably, an electromagnetic push rod one is installed in the mounting block. The output end of the electromagnetic push rod one is connected to a second arc block facing the first arc block and the copper wire. A heating plate is installed in the second arc block.

[0010] Preferably, it further includes a suction component. The suction component includes a fixed box installed in the movable frame. One side of the fixed box is fixedly communicated with a fixed suction head. A movable suction head is slidably sleeved in the fixed suction head. A suction fan is installed on the movable frame above the fixed box. The suction fan is fixedly communicated with a T-shaped pipe. A plurality of fixed pipes arranged horizontally are fixedly communicated with the T-shaped pipe. The other end of the fixed pipe is communicated with the fixed box.

[0011] Preferably, both sides of the bottom of the movable suction head are connected with tooth blocks capable of moving in the mounting block. A rack is connected above the fixed block. A gear is movably installed above the mounting block between the rack and the tooth blocks. The upper and lower parts of the gear can be engaged with the tooth block and the rack respectively.

[0012] Preferably, a closing cover is hinged above the movable suction head. A net plate is fixedly installed in the movable suction head. A filter cotton is movably sleeved in the movable suction head below the closing cover.

[0013] Preferably, it further includes an erasing component. The erasing component is respectively installed on the cleaning mechanism and the workbench. The erasing component includes a cleaning box installed on the workbench. Rubber cleaner is contained in the cleaning box. A net frame is fixedly installed in the cleaning box.

[0014] Preferably, a connecting frame is connected to the inner side of the mounting block. An electromagnetic push rod two is connected to the inner side of the connecting frame. The output end of the electromagnetic push rod two is hinged to a movable plate. A wiping cotton capable of abutting against the net frame is connected to the movable plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In the present invention, by providing a copper wire and a piston rod, when the copper wire moves and abuts against the adhered glue chips, the copper wire will be resisted and pulled by the adhered glue chips. At this time, as the movable frame and the mounting block move, the piston rod can be driven by the fixed block to extend out of the air cylinder. Meanwhile, the first spring is compressed, and under the restoring force of the first spring, pressure can be exerted on the pressure sensing element through the pressing plate. At this time, the control end will determine that the copper wire has encountered adhered glue chips during its travel, and control the cross - moving frame to drive the cleaning mechanism to stop moving further. At the same time, the first electromagnetic push rod and the heating plate are started. Due to the operation of the first electromagnetic push rod, the second arc block and the heating plate can be driven to abut against the copper wire. Meanwhile, the second arc block heats the copper wire. Through the heat conduction of the copper wire, the adhered glue chips can be heated and softened, gradually losing their adhesiveness and becoming loose and detached. This design can remove the adhered glue chips remaining on the lower die parting surface in a relatively gentle manner, thereby avoiding scratches on the die parting surface and causing damage.

[0017] In the present invention, by providing air holes, a rack and a gear, due to the movement of the fixed block, the gear can be driven to rotate by the rack. Meanwhile, the toothed block and the movable suction head are engaged and driven to move along the fixed suction head following the pulling of the copper wire, so that the movable suction head always faces the position of the adhered glue chips, ensuring that the glue chips can be sucked into the movable suction head after losing their adhesiveness. When the adhered glue chips become loose and detached, under the restoring force of the first spring, the piston rod and the fixed block can be driven to retract and reset. Meanwhile, the copper wire will gradually return to its straight state. During the reset process of the piston rod, due to the relatively small diameter of the air holes and the low exhaust efficiency, the reset speed of the piston rod can be reduced, and at the same time, the speed of the copper wire returning to its straight state can be prevented from being too fast, preventing the loosened and detached glue chips from splashing under the rapid rebound of the copper wire. Thus, it can be ensured that the glue chips can be sucked into the movable suction head after being softened, loosened and detached.

[0018] In the present invention, by providing a movable plate and a wiping cotton, after the piston rod is completely reset, the pressure sensing element will lose the pressure it receives. At this time, the control end drives the cross - moving frame to drive the cleaning mechanism to move again, and at the same time, the second electromagnetic push rod is started. The output end can drive the movable plate and the wiping cotton to descend and contact the lower die parting surface. As the cross - moving frame moves, the adhered glue chip - original adhesion position can be wiped by the wiping cotton contaminated with a cleaning agent, thereby wiping off the trace residues after the glue chips are detached, and further completely removing the adhered glue chips.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0032] As shown Figures 1 to 11 in the figure, the present invention provides a rubber injection molding machine for a cushion assembly, which includes a workbench 1, an injection mechanism 2, a moving frame 3, a lower mold 4, an upgrading frame 5, an upper mold 6, a transverse moving frame 7 and a cleaning mechanism 8;

[0033] The injection mechanism 2 is arranged on the workbench 1. The moving frame 3 is slidably installed on the workbench 1 through an electromagnetic slide rail. The lower mold 4 is slidably installed on the moving frame 3 and is driven by a lead screw motor. The upper mold 6 is arranged below the upgrading frame 5, and the lower mold 4 is arranged below the moving frame 3. The transverse moving frame 7 is slidably installed on the workbench 1 through an electromagnetic slide rail, and the cleaning mechanism 8 is slidably installed on the transverse moving frame 7 and is driven by a lead screw motor;

[0034] The cleaning mechanism 8 includes a movable frame 81. Two mounting blocks 82 are respectively connected to the front and rear of one side of the movable frame 81. An air cylinder 83 is fixedly installed in the mounting block 82. A piston rod 84 is sleeved in the air cylinder 83. An air hole 85 is opened in the piston rod 84. One end of the air hole 85 extends to the outside of the air cylinder 83 and a fixed block 89 is fixedly sleeved on the outside. A guide wheel 811 is movably installed in the mounting block 82. An arc-shaped block one 812 is connected to one side in the mounting block 82. The number of the fixed blocks 89 is two. A copper wire 810 is connected to one side of each of the two fixed blocks 89. The copper wire 810 can pass through the arc-shaped block one 812 and the guide wheel 811.

[0035] Adopting the above scheme: When the copper wire 810 moves and abuts against the adhered glue chips, the copper wire 810 will be resisted and pulled by the adhered glue chips. At this time, with the movement of the movable frame 81 and the mounting block 82, the piston rod 84 can be driven by the fixed block 89 to extend out of the air cylinder 83. At this time, it will be determined that the advancing path of the copper wire 810 encounters the adhered glue chips. When the copper wire 810 is heated, the adhered glue chips can be heated and softened, so that they gradually lose their adhesiveness and become loose and detached.

[0036] As shown Figure 6 and Figure 7 in the figure, a first spring 86 is sleeved on the outside of the piston rod 84. One end of the first spring 86 is connected to the piston rod 84, and the other end of the first spring 86 is connected to a pressing plate 87. The other end of the pressing plate 87 abuts against a pressure sensing element 88 installed in the air cylinder 83.

[0037] Adopting the above scheme: When the fixed block 89 drives the piston rod 84 to extend out of the air cylinder 83, the first spring 86 can be compressed, and under the action of the elastic force recovery of the first spring 86, the pressure sensing element 88 can be pressed through the pressing plate 87. At this time, the control end will determine that the advancing path of the copper wire 810 encounters the adhered glue chips.

[0038] As shown Figure 6 and Figure 7As shown, an electromagnetic push rod 813 is installed inside the mounting block 82. The output end of the electromagnetic push rod 813 is connected to an arc block 814 facing the arc block 812 and the copper wire 810. A heating plate 815 is installed inside the arc block 814.

[0039] Adopting the above solution: When the electromagnetic push rod 813 and the heating plate 815 are started, due to the operation of the electromagnetic push rod 813, the arc block 814 and the heating plate 815 can be driven to abut against the copper wire 810. At the same time, the arc block 814 heats the copper wire 810, so that the copper wire 810 can be heated.

[0040] As Figure 4 and Figure 5 shown, it further includes an absorption component 9. The absorption component 9 includes a fixed box 91. The fixed box 91 is installed inside the movable frame 81. One side of the fixed box 91 is fixedly communicated with a fixed suction head 92. An active suction head 93 is slidably sleeved inside the fixed suction head 92. A suction fan 99 is installed on the movable frame 81 above the fixed box 91. The suction fan 99 is fixedly communicated with a T-shaped pipe 97. A plurality of fixed pipes 98 arranged horizontally are fixedly communicated with the T-shaped pipe 97. The other end of the fixed pipe 98 is communicated with the fixed box 91.

[0041] Adopting the above solution: The control end drives the transverse moving frame 7 to drive the cleaning mechanism 8 to move downward towards the lower mold 4, so that the copper wire 810 can contact the parting surface of the lower mold 4 and move on the parting surface. At the same time, the suction fan 99 operates, and a negative pressure is formed in the fixed pipe 98, the fixed box 91, the fixed suction head 92 and the active suction head 93 through the T-shaped pipe 97, and the glue chips remaining on the parting surface of the lower mold 4 are continuously sucked, so that the glue chips can be directly sucked into the active suction head 93.

[0042] As Figure 3 、 Figure 8 、 Figure 10 and Figure 11 shown, both sides of the bottom of the active suction head 93 are connected with tooth blocks 94 that can move inside the mounting block 82. A rack 95 is connected above the fixed block 89. A gear 96 is movably installed above the mounting block 82 between the rack 95 and the tooth blocks 94. The upper and lower parts of the gear 96 can be meshed with the tooth blocks 94 and the rack 95 respectively.

[0043] Adopting the above solution: Due to the movement of the fixed block 89, the gear 96 can be driven to rotate through the rack 95. At the same time, the tooth blocks 94 and the active suction head 93 are meshed and driven to move along the fixed suction head 92 following the pulling of the copper wire 810, so that the active suction head 93 always faces the position where the glue chips are adhered, ensuring that the glue chips can be sucked into the active suction head 93 after losing adhesion.

[0044] As Figure 4 and Figure 5As shown, a closed cover 910 is hinged on the upper part of the movable suction head 93 , a mesh plate 911 is fixedly installed inside the movable suction head 93 , and a filter cotton 912 located below the closed cover 910 is movably sleeved inside the movable suction head 93 .

[0045] With the above solution, the rubber scraps sucked into the movable suction head 93 will be intercepted by the filter cotton 912, and the operator can open the sealing cover 910 and take out the filter cotton 912 for replacement.

[0046] like Figure 2 , Figure 4 and Figure 8 As shown, it also includes an erasing component 10, which is respectively installed on the cleaning mechanism 8 and the workbench 1. The erasing component 10 includes a cleaning box 104, which is installed on the workbench 1. The cleaning box 104 is filled with rubber cleaner, and a screen frame 105 is fixedly installed in the cleaning box 104.

[0047] The above scheme is adopted: as the cleaning mechanism 8 rises, the electromagnetic push rod 2 101, the movable plate 102 and the wiping cotton 103 can be driven to rise together, and the wiping cotton 103 soaked in the detergent is lifted out of the liquid surface. At the same time, the control end starts the electromagnetic push rod 2 101, driving the movable plate 102 and the wiping cotton 103 to further rise. When the wiping cotton 103 is separated from the liquid surface, the wiping cotton 103 will continue to abut against the mesh frame 105, thereby squeezing out the excess detergent in the wiping cotton 103. After the wiping cotton 103 is separated from the mesh frame 105, the wiping cotton 103 will swing from the vertical state to the horizontal state under the action of gravity.

[0048] like Figure 2 , Figure 4 and Figure 8 As shown, the inner side of the mounting block 82 is connected to a connecting frame 106 , the inner side of the connecting frame 106 is connected to an electromagnetic push rod 101 , the output end of the electromagnetic push rod 101 is hinged with a movable plate 102 , and the movable plate 102 is connected to a wiping cotton 103 that can abut against the screen frame 105 .

[0049] The above scheme is adopted: when the electromagnetic push rod 101 is started, the output end can drive the movable plate 102 and the wiping cotton 103 to descend and contact the parting surface of the lower mold 4. As the transverse frame 7 moves, the wiping cotton 103 soaked in detergent can wipe the position where the glue crumbs were originally stuck, so as to wipe off the trace residue after the glue crumbs are detached.

[0050] The working principle and use process of the present invention:

[0051] During use, the operation of the injection mechanism 2 can inject rubber into the interior formed by the clamping of the upper mold 6 and the lower mold 4, and then cool and solidify it through the cooling mechanism. After that, the control end controls the discharging movement of the moving frame 3. The lifting frame 5 drives the upper mold 6 and the lower mold 4 to open under the drive of the lead screw motor. After the demolding of the cushion assembly is completed, the cleaning mechanism 8 rises under the drive of the lead screw motor, raising the copper wire 810 to the parting surface of the lower mold 4. Since the cleaning mechanism 8 rises, it can drive the electromagnetic push rod II 101, the movable plate 102, and the wiping cotton 103 to rise together, lifting the wiping cotton 103 in the soaked cleaning agent out of the liquid surface. At the same time, the control end activates the electromagnetic push rod II 101, driving the movable plate 102 and the wiping cotton 103 to rise further. When the wiping cotton 103 leaves the liquid surface, the wiping cotton 103 will continue to abut against the wire mesh frame 105, thereby squeezing out the excess cleaning agent in the wiping cotton 103. After the wiping cotton 103 separates from the wire mesh frame 105, the wiping cotton 103 will swing from the vertical state to the horizontal state under the action of gravity.

[0052] The control end drives the transverse moving frame 7 to drive the cleaning mechanism 8 to move towards the lower mold 4, enabling the copper wire 810 to contact the parting surface of the lower mold 4 and move on the parting surface. At the same time, the exhaust fan 99 operates, creating a negative pressure through the T-shaped pipe 97 in the fixed pipe 98, the fixed box 91, the fixed suction head 92, and the movable suction head 93, and continuously sucking the residual rubber chips on the parting surface of the lower mold 4. Some rubber chips can be directly sucked into the movable suction head 93 and retained on the filter cotton 912. Some electrostatically attached rubber chips can be pushed under the scraping thrust of the copper wire 810 to make them move away from their original electrostatic attachment positions, so that the electrostatically attached rubber chips can also be sucked into the movable suction head 93, and thus the removal of electrostatically attached rubber chips can be achieved.

[0053] When the copper wire 810 moves and abuts against the adhered glue debris, the copper wire 810 will be resisted and pulled by the adhered glue debris. At this time, as the movable frame 81 and the mounting block 82 move, the piston rod 84 can be driven by the fixed block 89 to extend out of the air cylinder 83. At the same time, the first spring 86 is compressed, and under the action of the elastic force recovery of the first spring 86, the pressure sensing element 88 can be pressed by the pressing plate 87. At this time, the control end will determine that the copper wire 810 encounters adhered glue debris during its travel, and control the transverse moving frame 7 to drive the cleaning mechanism 8 to stop moving forward. At the same time, the first electromagnetic push rod 813 and the heating plate 815 are started. Due to the operation of the first electromagnetic push rod 813, the second arc block 814 and the heating plate 815 can be driven to abut against the copper wire 810. At the same time, the second arc block 814 heats the copper wire 810. Through the heat conduction of the copper wire 810, the adhered glue debris can be heated and softened, so that it gradually loses its adhesiveness and becomes loose and detached. At this time, under the action of the elastic force recovery of the first spring 86, the piston rod 84 and the fixed block 89 can be driven to reset and retract. At the same time, the copper wire 810 will gradually reset and straighten. During the reset process of the piston rod 84, since the aperture of the air hole 85 is small and the exhaust efficiency is low, the reset speed of the piston rod 84 can be reduced, and at the same time, the speed of the copper wire 810 resetting and straightening can be prevented from being too fast, so as to prevent the glue debris after loosening and detachment from splashing under the rapid rebound of the copper wire 810, so as to ensure that it can be sucked into the movable suction head 93 after being softened, loosened and detached.

[0054] Due to the movement of the fixed block 89, the gear 96 can be driven to rotate by the rack 95, and at the same time, the tooth block 94 and the movable suction head 93 can be engaged and driven to move along the fixed suction head 92 following the pulling of the copper wire 810, so that the movable suction head 93 always faces the position of the adhered glue debris, further ensuring that the glue debris can be sucked into the movable suction head 93 after losing its adhesiveness.

[0055] After the piston rod 84 is completely reset, the pressure sensing element 88 will lose the pressure it receives. At this time, the control end drives the transverse moving frame 7 to drive the cleaning mechanism 8 to move again, and at the same time, the second electromagnetic push rod 101 is started. The output end can drive the movable plate 102 and the wiping cotton 103 to descend and contact the parting surface of the lower die 4. As the transverse moving frame 7 moves, the adhered glue debris can be wiped by the wiping cotton 103 contaminated with the cleaning agent at the original adhered position, so that the trace residues after the glue debris is detached can be wiped off. After the wiping is completed, the control end controls the second electromagnetic push rod 101 to drive the movable plate 102 and the wiping cotton 103 to rise and recover.
