DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 9 The present invention provides an injection molding bending mechanism, and the technical solution is as follows:

[0041] An injection molded part bending mechanism, comprising:

[0042] Controller 1;

[0043] A base 2, wherein a controller 1 is mounted on an outer side wall of the base 2;

[0044] A conveyor belt 3, wherein the conveyor belt 3 is installed on the surface of the base 2;

[0045] A hydraulic punch 4, wherein the hydraulic punch 4 is fixedly connected to a hydraulic cylinder, the hydraulic cylinder is fixedly connected to a connecting seat, and the connecting seat is fixedly connected to the base 2;

[0046] A push rod 14, wherein the push rod 14 is fixedly connected to the inner wall of the base 2;

[0047] Also includes:

[0048] Bending devices, a plurality of said bending devices are placed on the conveyor belt 3, and said bending devices slide relative to the base 2;

[0049] A cooling device is fixedly installed inside each of the plurality of bending devices.

[0050] When in use, first, the staff puts the injection molded part into the bending device, operates the controller 1 to start the machine, and the conveyor belt 3 drives the bending device to stop just below the hydraulic punch 4. At this time, the hydraulic punch 4 presses down to bend. After the bending is completed, the cooling device is started, so that the injection molded part is quickly cooled after bending. The conveyor belt 3 drives the bending device and the bent injection molded part to the push rod 14 and then stops. The push rod 14 pushes the bent injection molded part out, and the bending device returns to the staff along the conveyor belt 3. By setting the cooling device, the injection molded part can be quickly cooled after the bending is completed, avoiding the problem of rebound and deformation of the injection molded part after bending.

[0051] As an embodiment of the present invention, the bending device includes: the bending device includes a plurality of shells 51 fixedly installed on the conveyor belt 3, four corners of the upper end of the shell 51 are fixedly installed with No. 1 springs 6, the upper ends of the four No. 1 springs 6 are commonly fixedly connected with an extrusion plate 53, the extrusion plate 53 is V-shaped, a guide rod 15 is slidably installed inside a side wall of the shell 51, the guide rod 15 is fixedly connected to the extrusion plate 53, two forming plates 10 are symmetrically fixedly connected inside the shell 51, an empty groove is formed between the two forming plates 10, a plurality of No. 2 springs 7 are fixedly connected in the middle of the bottom of the empty groove, a support plate 54 is commonly fixedly connected to the top of the plurality of No. 2 springs 7, and the support plate 54 is located directly below the middle of the extrusion plate 53.

[0052] During use, the staff puts the injection molded part on the support plate 54, and the shell 51 is driven by the conveyor belt 3 to the bottom of the hydraulic punch 4 and stops. At this time, the hydraulic punch 4 is pressed down, and the hydraulic punch 4 drives the extrusion plate 53 to move downward, thereby squeezing the injection molded part into the shell 51, compressing the No. 1 spring 6, and the guide rod 15 moves downward to squeeze the support plate 54 and the No. 2 spring 7 into the shell 51 until the spring limit. At this time, the extrusion plate 53 and the two forming plates 10 squeeze and bend the injection molded part. After completing the bending action, the hydraulic punch 4 moves upward to recover. By setting the extrusion plate 53 and the two forming plates 10, the injection molded part is bent. Then, through the guide rod 15, it is avoided that the No. 1 spring 6 will swing randomly when pressed down, causing problems in the bending of the injection molded part, thereby improving stability.

[0053] As an embodiment of the present invention, grooves 52 are symmetrically provided at the upper ends of both side walls of the housing 51 , and two buckles 8 cooperating with the grooves 52 are fixedly mounted at the lower end of the extrusion plate 53 .

[0054] When in use, when the hydraulic punch 4 drives the extrusion plate 53 to press down, when it is extruded to a certain extent, the buckles 8 on both sides enter the grooves 52, and then the buckles 8 are engaged with the grooves 52, so that the extrusion plate 53 and the shell 51 are fixed, so that the injection molded part can maintain a bent state between the extrusion plate 53 and the molding plate 10. By setting the buckles 8 and the grooves 52, the injection molded part can be stably maintained in a bent state between the extrusion plate 53 and the molding plate 10, thereby avoiding rebound and deformation of the injection molded part after bending, thereby improving stability.

[0055] As an embodiment of the present invention, an elastic block 16 cooperating with the guide rod 15 is provided inside a side wall of the housing 51, a heating wire is provided inside the support plate 54, and the elastic block 16 is electrically connected to the heating wire.

[0056] During use, when the hydraulic punch 4 drives the extrusion plate 53 to press down, the extrusion plate 53 drives the guide rod 15 to move downward. When the injection molded part has not yet contacted the forming plate 10, the guide rod 15 squeezes the elastic block 16 toward the outer wall of the shell 51. The elastic block 16 is squeezed and gives an electrical signal to the heating wire. The heating wire starts to heat up, and then the support plate 54 is heated, so that the injection molded part to be bent is heated. By arranging the guide rod 15, the elastic block 16 and the heating wire in cooperation, the injection molded part can be preheated before bending, so that the injection molded part can be bent more smoothly, thereby improving the stability of the bending.

[0057] As an embodiment of the present invention, two through grooves 26 that penetrate into the groove 52 are opened on the outer wall of the shell 51, and two No. 4 springs 27 are symmetrically fixedly connected inside the two through grooves 26. The four No. 4 springs 27 are commonly connected to each other with a movable rod 9 for pushing the buckle 8.

[0058] When in use, after the bending is completed, the buckle 8 is engaged with the groove 52. After the shape is fixed, it hits the movable rod 9, and the movable rod 9 hits the buckle 8, so that the buckle 8 is separated from the groove 52, and the extrusion plate 53 is driven to move upward with the restoring force of the No. 1 spring 6, so that the extrusion plate 53 is separated from the shell 51, allowing the formed injection molded part to be separated. Due to the elastic force of the No. 4 spring 27, the movable rod 9 is restored to its initial state to avoid deviation when the movable rod 9 is hit next time. By setting the movable rod 9, the injection molded part can be automatically separated without manual operation, thereby improving production efficiency.

[0059] As an embodiment of the present invention, the cooling device includes a water-cooling circulation pump 11 fixedly installed inside the molding plate 10 on one side, and multiple water-cooling circulation pipes 17 are fixedly connected under the surface of the two molding plates 10, and the multiple water-cooling circulation pipes 17 are all connected to the water-cooling circulation pump 11 pipeline. An elastic button 18 is fixedly installed on the molding plate 10 on the side of the water pump circulation pump, and the elastic button 18 is electrically connected to the water-cooling circulation pump 11. An alarm device for detecting whether the water-cooling circulation pipe 17 is leaking is provided inside the two molding plates 10.

[0060] When in use, when the hydraulic punch 4 drives the extrusion plate 53 to press down, the injection molded part is pressed down, and then the support plate 54 compresses the No. 2 spring 7. When the buckle 8 is buckled with the groove 52, the No. 2 spring 7 is compressed to the extreme, the support plate 54 contacts the elastic button 18, and the elastic button 18 is squeezed into the inside of the molding plate 10 by the support plate 54. The elastic button 18 gives an electrical signal to the water-cooling circulation pump 11, so that the water-cooling circulation pump 11 starts, and cold water flows in the water-cooling circulation pipe 17, so that the molded injection molded part is quickly cooled down. When the buckle 8 is disengaged from the groove 52, due to the restoring force of the No. 2 spring 7, the support plate 54 and the molded injection molded part are driven to move upward, the elastic button 18 loses pressure, and stops giving the water-cooling circulation pump 11 an electrical signal, and the water-cooling circulation pump 11 stops. By setting the support plate 54, the elastic button 18 and the water-cooling circulation pump 11 in coordination, the molded injection molded part is quickly cooled down, thereby avoiding the possibility of rebound and deformation of the molded injection molded part, thereby improving stability.

[0061] As an embodiment of the present invention, the alarm device includes a collection box 19 fixedly installed at the bottom of the outer shell 51, and two connection rods 20 are provided in the middle of the collection box 19. The outer surface of the outer shell 51 is provided with two warning lights 22 corresponding to the two forming plates 10, and the connection rods 20 are electrically connected to the warning lights 22. A water channel 21 for collecting water is fixedly connected between the forming plates 10 and the collection box 19.

[0062] During use, when the water-cooling circulation pump 11 is started, cold water flows in the water-cooling circulation pipe 17 to cool the molded injection molded parts. Because the hydraulic punch 4 drives the extrusion plate 53 to press down, vibration may be generated. Long-term operation may cause the water-cooling circulation pipe 17 to rupture or be damaged, and then cause the cold water in the water-cooling circulation pipe 17 to flow out. The outflowing cold water flows into the collecting box 19 along the water channel 21 or the inner wall of the outer shell 51, contacts the power rod 20 to be energized, and the warning light 22 on the outer wall of the outer shell 51 starts to flash to alarm. By providing the collecting box 19 and the warning light 22, the staff can be reminded in time when the water-cooling circulation pipe 17 is ruptured or damaged, allowing the staff to repair and replace it, and can objectively observe the condition of the water-cooling circulation pipe 17 inside the outer shell 51, thereby improving safety.

[0063] As an implementation mode of the present invention, the power supply can only be conducted after the head of the power rod 20 contacts water.

[0064] During use, when the support plate 54 is heated, or due to some external factors, some water will be collected in the collection box 19. When the water level is not enough to touch the head of the connecting rod 20, the connecting rod 20 is not powered on, and the warning light 22 will not flash. When the water-cooling circulation pipe 17 is broken or damaged, the cold water inside leaks out, and the water level in the collection box 19 will soon touch the head of the connecting rod 20, the connecting rod 20 is powered on, and the warning light 22 flashes to alarm. This avoids some external factors that cause the warning light 22 to flash to alarm, thereby improving accuracy.

[0065] As an embodiment of the present invention, two support bars 23 are fixedly installed on both sides of the outer wall of the shell 51, and a trigger plate 24 is hinged on the two support bars 23. No. 3 springs 25 are fixedly installed on the outer walls of both sides of the shell 51, and the two No. 3 springs 25 are fixedly connected to the trigger plate 24, and the trigger plate 24 is electrically connected to the controller 1.

[0066] When in use, the top of the support plate 54 and the two molding plates 10 are slightly away from the top of the shell 51, just enough to allow the injection molded parts to be stuck. When placing the injection molded parts, the staff inserts the injection molded parts into the shell 51, and the four sides of the injection molded parts are completely flush with the inner wall of the shell 51 to place them flat. When the staff places the injection molded parts, they do not completely insert the injection molded parts into the shell 51, or one side is tilted, or even the injection molded parts are not placed flat. The conveyor belt 3 drives multiple shells 51 to move, and the staff does not place the injection molded parts flat when placing them. , resulting in problems with the bending of the injection molded parts. During extrusion, the injection molded parts will be squeezed out or even broken. The overflowed and broken injection molded parts will touch the trigger plates 24 on both sides. The trigger plates 24 are squeezed outward and rotated, driving the No. 3 spring 25 to extend outward, and then giving an electrical signal to the controller 1 to stop the entire conveyor belt 3. By setting the trigger plate 24 and the controller 1 to cooperate with each other, it can be automatically stopped in time when a situation occurs, avoiding problems affecting the subsequent machine operation, further reducing the output of unqualified bent injection molded parts, and improving production efficiency.

[0067] As an embodiment of the present invention, a striker 12 is provided on the inner wall of the base 2, and a cylinder is fixedly connected to the input end of the striker 12. Round rods 13 that cooperate with the grooves 52 on the outer wall of the shell 51 are provided on both sides of the striker 12.

[0068] When in use, the shell 51 moves with the conveyor belt 3 to the front of the impact rod 12 and stops. The conveyor belt 3 is the existing technology and can stably stop in front of the impact rod 12. At this time, the impact rod 12 starts, and the two round rods 13 just enter the through groove 26 and hit the movable rod 9, so that the movable rod 9 pushes the buckle 8, and then the buckle 8 disengages from the groove 52. After the impact rod 12 hits the movable rod 9, it is quickly recovered to prevent the shell 51 from hitting the round rod 13 and causing it to move during movement. By arranging the impact rod 12 and the movable rod 9 to cooperate with each other, when the shell 51 stops in front of the impact rod 12, the buckle 8 can be disengaged from the groove 52, thereby improving production efficiency.

[0069] Working principle: When in use, first, the staff puts the injection molded part on the support plate 54, operates the controller 1 to start the machine, and multiple shells 51 move with the conveyor belt 3. When the shell 51 moves to the bottom of the hydraulic punch 4, the conveyor belt 3 stops. At this time, the hydraulic punch 4 presses down, and the hydraulic punch 4 drives the extrusion plate 53 to move downward, and then squeezes the injection molded part into the shell 51, compressing the No. 1 spring 6, and the guide rod 15 moves downward. When the injection molded part has not yet contacted the molding plate 10, the guide rod 15 squeezes the elastic block 16 toward the outer wall of the shell 51. The elastic block 16 is squeezed and gives an electrical signal to the heating wire. The heating wire begins to heat up, and then the support plate 54 is heated, so that the bending part of the injection molded part is preheated, and the hydraulic punch 4 squeezes the support plate 54 and the No. 2 spring 7 into the shell 51 until the No. 2 spring 7 is extreme. At this time, the buckles 8 on both sides enter the groove 52, and then the buckle 8 is engaged with the groove 52, so that the extrusion plate 53 and the shell 51 are fixed. At the same time, the extrusion plate 53 and the two The molding plate 10 squeezes and bends the injection molded part into shape, and at the same time, the support plate 54 contacts the elastic button 18, and the elastic button 18 is squeezed into the inside of the molding plate 10 by the support plate 54. The elastic button 18 gives an electrical signal to the water cooling circulation pump 11, so that the water cooling circulation pump 11 starts, and cold water flows in the water cooling circulation pipe 17, so that the molded injection molded part is quickly cooled. The housing 51 moves with the conveyor belt 3 to the front of the striker 12 and stops. At this time, the striker 12 starts, and the two round rods 13 just enter the through groove 26 and strike The striking rod 9 pushes the buckle 8, and the buckle 8 disengages from the groove 52. Due to the restoring force of the No. 2 spring 7, the support plate 54 and the molded injection molded part are driven upward, the elastic button 18 loses pressure, and the electrical signal to the water-cooling circulation pump 11 stops. The conveyor belt 3 drives the shell 51 and the bent injection molded part to the push rod 14 and then stops. The push rod 14 pushes the bent injection molded part out, and the shell 51 returns to the staff along the conveyor belt 3, and this process is repeated.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
