Description

Technical Field

[0001] The present invention belongs to the technical field of processing of metal and plastic parts, and specifically relates to a rapid processing and forming device for metal and plastic parts. Background Art

[0002] Metal and plastic refers to adding metal structural parts or accessories to plastic products to enhance their strength and practicality, while also increasing aesthetics and texture. It is widely used in daily life and various industrial productions. For example, screw metal and plastic parts are based on screws, and plastic parts are injection-molded at one end of the screw using a processing and forming device, so that the screw can be easily twisted and disassembled without using a screwdriver, thereby improving the flexibility of the use of metal parts.

[0003] A patent with the publication number of CN116714161B discloses a rapid processing and forming device for metal and plastic parts. This patent detects the movement of the punching head by setting an optoelectronic sensor on the bracket, enabling it to determine whether the punching head has completed punching, and then transmitting the signal to the single-chip microcomputer inside the electric control box. The single-chip microcomputer controls the motor to start rotating to make the punching groove at the top of the turntable rotate to the number of turns directly below the punching head, so that the punching groove rotates, facilitating the punching machine to work again. This structure does not require personnel to frequently replace products for punching, and can achieve continuous and automatic processing of the device. Operators can replace products on one side far from the punching head, avoiding the problem of potential safety hazards when working under the punching machine.

[0004] The above solution still has some problems in actual application. Usually, when manufacturing metal and plastic parts, it is necessary to first manufacture the metal parts using external processing equipment or stamping equipment, and then place the metal parts into the processing mold and pour injection liquid into the processing mold to form plastic parts on the outside or surface of the metal parts, thereby realizing the production and manufacturing of metal and plastic parts. However, due to the inability to automatically pour the injection liquid and accurately control the pouring amount of the injection liquid, it is necessary to repeat the pouring operation multiple times, resulting in a distinct layer situation in the plastic parts of the screw metal and plastic parts, and the hardness of the plastic parts not meeting the standard and being unable to withstand force, thus reducing the production efficiency and quality of the screw metal and plastic parts.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figures 1 to 9As shown in the figure, a rapid processing and forming device for hardware plastic parts according to an embodiment of the present invention includes a base 1. A circular protective cabinet 2 is fixedly connected to the upper end surface of the base 1. A rotating groove 30 is opened on the upper end surface of the circular protective cabinet 2. A rotating injection disk 4 is rotatably connected to the inner cavity of the rotating groove 30. A gear ring 20 is fixedly connected to the lower end of the rotating injection disk 4 outside the inner cavity of the rotating groove 30. The rotating injection disk 4 is hollow. An electric push rod 7 is installed at the bottom of the inner cavity of the rotating groove 30. The piston rod end of the electric push rod 7 is fixedly connected to a support plate 8. A folding pipe 16 is fixedly communicated with one side of the lower end surface of the support plate 8. A sealing injection assembly 9 is arranged at the lower end of the folding pipe 16;

[0036] And the sealing injection assembly 9 includes a sealing plate 91 fixedly communicated with the lower end of the folding pipe 16. A shaping block 92 is fixedly connected to the lower end surface of the sealing plate 91. And an injection port 97 is opened on the lower end surface of the shaping block 92;

[0037] A plurality of injection grooves 6 are uniformly opened on the upper end surface of the rotating injection disk 4. And screws and hardware parts 29 are installed in the inner cavities of the plurality of injection grooves 6.

[0038] Specifically, in the prior art when manufacturing screw hardware plastic parts, usually the screw hardware parts are placed into an injection mold, and then an injection assembly is used to pour injection liquid into the injection mold. After waiting for the injection liquid to cool, the screw hardware plastic parts are demolded and taken out. Then, the screw hardware parts are placed into the injection mold again in sequence to inject and produce screw hardware plastic parts. However, due to the inability to automatically pour the injection liquid and accurately control the pouring amount of the injection liquid, it is necessary to repeat the pouring operation multiple times, resulting in a distinct layer and unqualified quality such as hardness in the plastic part of the screw hardware plastic parts, thus reducing the production efficiency of the screw hardware plastic parts;

[0039] In the present invention, the screw hardware parts 29 are vertically placed in the injection grooves 6 by using manual labor or a robotic arm, and then the rotating injection disk 4 is driven to rotate. After the rotating injection disk 4 drives the screw hardware parts 29 to move below the sealing injection assembly 9, the electric push rod 7 is started to drive the support plate 8 to move downward. Then, the support plate 8 drives the folding pipe 16 to move downward, and at the same time drives the sealing plate 91 to move synchronously. Further, the sealing plate 91 drives the shaping block 92 to slide into the injection groove 6, and at the same time the sealing plate 91 seals the injection groove 6. As the support plate 8 continues to move downward, the support plate 8 will cooperate with the sealing plate 91 to squeeze the folding pipe 16 to fold, and at the same time make the folding pipe 16 squeeze the injection liquid in the inner cavity, and inject it into the injection groove 6 through the injection port 97 to process the screw hardware plastic parts. After the injection is completed, the electric push rod 7 is started to drive the support plate 8 to move upward and reset, then the rotating injection disk 4 is driven to rotate again, and the support plate 8 is driven to move downward again for injection work, so as to be able to circularly process and manufacture the screw hardware plastic parts, thus solving the above problems.

[0040] Such asFigure 1 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 4 and Figure 5 , two second sliding grooves 93 are symmetrically formed in the inner wall of the injection port 97, and second springs 94 are fixedly connected to the bottoms of the inner cavities of the two second sliding grooves 93. One end of one second spring 94 is fixedly connected to a U-shaped sealing block 95, and one end of the other second spring 94 is fixedly connected to a conical sealing cutting block 96. The conical sealing cutting block 96 and the U-shaped sealing block 95 cooperate to seal the injection port 97 and cut off the injection liquid.

[0041] As Figure 1 , Figure 2 and Figure 9 As shown in Figure 1 , Figure 2 and Figure 9 , two limit columns 10 are slidably connected to one side of the upper end surface of the support plate 8, and sliding disks 31 are slidably mounted on the outsides of the two limit columns 10. A tension spring 11 is fixedly connected to the lower end surface of the sliding disk 31, one end of the tension spring 11 is fixedly connected to the support plate 8, and the lower ends of the two limit columns 10 are fixedly connected to the sealing plate 91.

[0042] Specifically, when injection molding screw hardware plastic parts, the electric push rod 7 is started to drive the support plate 8 to move downward, and the support plate 8 drives the limit columns 10 to move downward by means of the tension spring 11. At the same time, the limit columns 10 drive the sealing plate 91 to push the shaping block 92 downward, so that the shaping block 92 is inserted into the inner cavity of the injection groove 6, and the sealing plate 91 seals the injection groove 6. As the support plate 8 continues to move downward, the support plate 8 cooperates with the sealing plate 91 to push the limit columns 10 to move upward, and at the same time, the limit columns 10 cooperate with the sliding disks 31 to pull the tension spring 11 to expand, thereby squeezing and folding the folding tube 16. At the same time, the folding tube 16 squeezes the injection liquid in the inner cavity, and the injection liquid squeezes the conical sealing cutting block 96 and the U-shaped sealing block 95 into the inner cavity of the second sliding groove 93, and then is injected into the injection groove 6 through the injection port 97 for processing screw hardware plastic parts. After the injection groove 6 is filled with the injection liquid, the conical sealing cutting block 96 and the U-shaped sealing block 95 are bounced by the second spring 94, so that the conical sealing cutting block 96 cooperates with the U-shaped sealing block 95 to cut off the cooled injection liquid, thus facilitating the removal of the processed screw hardware plastic parts. When it is necessary to process according to the processed screw hardware plastic parts, the sliding disk 31 is removed and slid on the outside of the limit column 10 to adjust the position, and then the sliding disk 31 is fixed on the outside of the limit column 10 by means of the fastening bolt. Thus, the tension of the tension spring 11 can be used to push the sealing plate 91 downward, and at the same time, the sealing plate 91 drives the folding tube 16 to expand, adjusting the size of the inner cavity of the folding tube 16, thereby increasing the storage capacity of the injection liquid, so as to adjust the amount of injection liquid to be injected according to the screw hardware plastic parts to be processed, thus solving the problem that the existing rapid processing and forming equipment for hardware plastic parts cannot accurately control the injection amount of the injection liquid, resulting in the need for repeated injection operations, causing the plastic parts of the screw hardware plastic parts to have distinct layers and the quality such as hardness not meeting the standards, thereby reducing the production efficiency of the screw hardware plastic parts.

[0043] As Figure 4 、 Figure 5 and Figure 9 shown, on one side of the upper end face of the support plate 8, a heating tank 13 is installed. The lower end of the heating tank 13 is fixedly communicated with a feeding pipe 18. One end of the feeding pipe 18 is fixedly communicated with the support plate 8 and is communicated with the inner cavity of the folding pipe 16. A one-way valve 17 is arranged in the inner cavity of the support plate 8, and the one-way valve 17 can only be turned over and opened towards the inner cavity of the folding pipe 16.

[0044] As Figure 4 、 Figure 5 and Figure 9 shown, a pipe heater 12 is installed on the upper end face of the support plate 8, and the pipe heater 12 is installed with the feeding pipe 18 to heat the feeding pipe 18 to improve the fluidity of the injection molding liquid. The upper end of the pipe heater 12 is electrically connected with a wire 14 inside, and one end of the wire 14 is electrically connected with the heating tank 13. The piston rod end of the electric push rod 7 is fixedly connected with a support plate 15, and the support plate 15 is fixedly installed with the support plate 8.

[0045] Specifically, when injection molding screw hardware plastic parts, the plastic is processed and melted by starting the heating tank 13, and then the injection molding liquid is conveyed into the folding pipe 16 through the feeding pipe 18. During the startup process of the heating tank 13, the pipe heater 12 is powered through the wire 14, so that the pipe heater 12 heats and keeps the feeding pipe 18 warm, avoiding the situation that the injection molding liquid hardens due to cooling during the process of being conveyed from the feeding pipe 18 into the folding pipe 16. When the tension spring 11 pulls the sliding plate 31 to reset, the sliding plate 31 drives the limit post 10 to move downward, and at the same time, the limit post 10 pushes the sealing plate 91 to move downward, thereby driving the folding pipe 16 to expand and reset. When the folding pipe 16 expands and resets, a negative pressure is formed in the inner cavity to pump the one-way valve 17 to turn over and open, and at the same time, the injection molding liquid in the inner cavity of the feeding pipe 18 is extracted into the inner cavity of the folding pipe 16. When the sealing plate 91 squeezes the folding pipe 16, the injection molding liquid in the inner cavity of the folding pipe 16 is discharged for perfusion to produce screw hardware plastic parts, thus solving the problem that the existing hardware plastic part rapid processing and forming equipment cannot automatically quantitatively extract the injection molding liquid and perfusion the injection molding liquid into the injection molding groove, resulting in the problem of the production and processing efficiency of hardware plastic parts.

[0046] Embodiment 2

[0047] As Figure 1 、 Figure 4 and Figure 9As shown, a control box 3 is provided inside the front end of the circular protective cabinet 2, and a controller 22 is provided inside the control box 3. A plurality of storage grooves 26 are evenly formed on the lower end surface of the rotating injection disk 4, and an elastic member 28 is fixedly connected to the bottom of the inner cavity of the plurality of storage grooves 26. One end of the elastic member 28 is fixedly connected to a trigger button 27. One side of the upper end surface of the circular protective cabinet 2 is provided with a trigger 32 for starting the operation of the electric push rod 7.

[0048] As Figure 3 , Figure 4 , Figure 6 and Figure 9 shown, a servo motor 19 is installed inside the circular protective cabinet 2. The output shaft end of the servo motor 19 penetrates through the circular protective cabinet 2 and is fixedly connected to a gear disk 21 inside the rotating groove 30. The gear disk 21 is meshed and connected with a gear ring 20 for driving the rotation of the rotating injection disk 4.

[0049] Specifically, by using manual labor or a robotic arm to vertically place the screw hardware 29 in the injection groove 6, then starting the electric push rod 7 to drive the rotation of the rotating injection disk 4, and making the rotating injection disk 4 drive the screw hardware 29 to move. After the rotating injection disk 4 drives the screw hardware 29 to rotate under the sealing injection assembly 9, the elastic member 28 in the inner cavity of the storage groove 26 is used to bounce up the trigger button 27, and the trigger button 27 presses the trigger 32 to start the electric push rod 7. Then, the electric push rod 7 drives the support plate 8 to move downward, and at the same time drives the sealing plate 91 to move synchronously. Further, the sealing plate 91 drives the shaping block 92 to slide into the injection groove 6, and the sealing plate 91 seals the injection groove 6. As the support plate 8 continues to move downward, the support plate 8 cooperates with the sealing plate 91 to squeeze the folding tube 16 for folding, and at the same time makes the folding tube 16 squeeze the injection liquid in the inner cavity, and injects it into the injection groove 6 through the injection port 97 for processing the screw hardware plastic parts, thereby improving the automation degree of the hardware plastic part rapid processing and forming equipment, enabling it to circularly manufacture and process the screw hardware plastic parts, and improving the production efficiency of the screw hardware plastic parts.

[0050] As Figure 1 , Figure 3 and Figure 9 shown, a groove 23 is formed on one side of the circular protective cabinet 2. A threaded rod 24 is rotatably connected inside the groove 23. An adjusting plate 25 is threadedly connected to the outside of the threaded rod 24, and the adjusting plate 25 is slidably connected to the inner cavity of the groove 23. A semi-circular sliding groove is formed on the upper end surface of the adjusting plate 25, and a plurality of balls are evenly arranged inside the semi-circular sliding groove.

[0051] Specifically, when processing and manufacturing screw hardware plastic parts of different lengths, by driving the threaded rod 24 to rotate, and making the threaded rod 24 thread-drive the fixed plate 25 to slide in the inner cavity of the groove 23, and then making the fixed plate 25 move upward to adjust the position, so that the fixed plate 25 can better push the semi-circular slider 51 upward by using the semi-circular chute, and making the semi-circular slider 51 push the T-shaped sliding column 54 to extrude the material-return spring 53 upward, and further making the T-shaped sliding column 54 push the screw hardware 29 in the inner cavity of the limit groove 55, and making the screw hardware 29 push the plastic parts completed by injection molding out of the injection molding groove 6, so as to facilitate the collection of the processed screw hardware plastic parts and improve the recycling efficiency and convenience of the screw hardware plastic parts.

[0052] As Figure 1 , Figure 4 , Figure 6 and Figure 7 shown, a material-return component 5 is arranged on the lower end face of the rotating injection molding disc 4, and the material-return component 5 includes a limit groove 55 opened at the bottom of the inner cavity of the injection molding groove 6. A plurality of fixed cylinders 52 are fixedly communicated with the lower end face of the rotating injection molding disc 4, and the fixed cylinders 52 are communicated with the inner cavity of the limit groove 55. A plurality of material-return springs 53 are fixedly connected to the lower end face of the rotating injection molding disc 4, and one end of each of the plurality of material-return springs 53 is fixedly connected with a semi-circular slider 51. A T-shaped sliding column 54 is installed inside the upper end of the semi-circular slider 51, and the T-shaped sliding column 54 is slidably connected with the inner cavity of the fixed cylinder 52, and is used to push the screw hardware 29 for material return and recycling.

[0053] As Figure 4 , Figure 6 and Figure 7 shown, two first chutes 56 are symmetrically opened on the inner wall of the limit groove 55, and first springs 57 are fixedly connected to the bottoms of the inner cavities of the two first chutes 56. One end of each first spring 57 is fixedly connected with a blocking block 58, and the blocking block 58 is used to abut and position the screw hardware 29 and seal the inner cavity of the limit groove 55.

[0054] Specifically, after the processing and injection molding of the screw hardware plastic parts are completed, the rotating injection molding disk 4 is continuously driven to rotate, and the rotating injection molding disk 4 drives the processed screw hardware plastic parts to move synchronously. After the rotating injection molding disk 4 drives the semi-circular slider 51 to move to the fixed plate 25, the semi-circular slider 51 will slide into the semi-circular chute of the fixed plate 25. At the same time, the semi-circular slider 51 moves upward along the surface of the semi-circular chute, and then pushes the T-shaped sliding column 54 to squeeze the material discharging spring 53 to move upward. Furthermore, the T-shaped sliding column 54 pushes the screw hardware part 29 in the inner cavity of the limiting groove 55, and the screw hardware part 29 pushes the injection-molded plastic part out of the injection groove 6, so as to facilitate the collection of the processed screw hardware plastic parts. After the semi-circular slider 51 slides out of the semi-circular chute, the material discharging spring 53 will rebound the semi-circular slider 51, and the semi-circular slider 51 drives the T-shaped sliding column 54 to move downward for resetting. Then, the screw hardware part 29 is installed into the inner cavity of the limiting groove 55 again. At the same time, the first spring 57 in the inner cavity of the first chute 56 bounces up the abutting block 58, and the abutting block 58 presses the screw hardware part 29 in the inner cavity of the limiting groove 55 to keep it in a vertical state, preventing the screw hardware part from tilting after the plastic part is injection-molded. Thus, it solves the problem that in the existing rapid processing and forming equipment for hardware plastic parts, if the screw hardware part is not clamped and positioned to ensure its vertical state before the plastic part of the screw hardware part is processed and injection-molded, the screw hardware part will tilt after the plastic part of the screw hardware part is processed and injection-molded, resulting in the unqualified quality of the processed hardware plastic parts and making them unusable.

[0055] Working principle: When injection molding screw hardware plastic parts, start the electric push rod 7 to drive the support plate 8 to move downward. The support plate 8 drives the limit post 10 to move downward by means of the tension spring 11. At the same time, the limit post 10 drives the sealing plate 91 to push the shaping block 92 downward, so that the shaping block 92 is inserted into the inner cavity of the injection molding groove 6. And the sealing plate 91 seals the injection molding groove 6. As the support plate 8 continues to move downward, the support plate 8 cooperates with the sealing plate 91 to push the limit post 10 upward. At the same time, the limit post 10 cooperates with the sliding disk 31 to pull the tension spring 11 to expand, thereby squeezing and folding the folding tube 16. At the same time, the folding tube 16 squeezes the injection molding liquid in the inner cavity, and the injection molding liquid squeezes the conical sealing cut block 96 and the U-shaped sealing block 95 into the inner cavity of the second chute 93. Then, it is injected into the injection molding groove 6 through the injection port 97 to process the screw hardware plastic parts. After injecting the injection molding liquid into the injection molding groove 6, the conical sealing cut block 96 and the U-shaped sealing block 95 are bounced up by using the second spring 94. Then, the conical sealing cut block 96 cooperates with the U-shaped sealing block 95 to cut off the cooled injection molding liquid, so as to facilitate the removal of the processed screw hardware plastic parts. When it is necessary to process according to the processed screw hardware plastic parts, remove the sliding disk 31 and slide it outside the limit post 10 to adjust the position. Then, fix the sliding disk 31 outside the limit post 10 by using the fastening bolt. Then, the tension of the tension spring 11 can be used to push the sealing plate 91 downward. At the same time, the sealing plate 91 drives the folding tube 16 to expand, adjusting the size of the inner cavity of the folding tube 16, thereby increasing the storage capacity of the injection molding liquid, so as to adjust the amount of injection molding liquid to be injected according to the screw hardware plastic parts to be processed;

[0056] When injection molding screw hardware plastic parts, start the heating tank 13 to process and melt the plastic. Then, the injection molding liquid is transported into the folding tube 16 through the feeding pipe 18. During the start-up process of the heating tank 13, the pipeline heater 12 is powered by the wire 14, so that the pipeline heater 12 heats and insulates the feeding pipe 18, avoiding the situation that the injection molding liquid cools and hardens during the transportation from the feeding pipe 18 to the folding tube 16. When the tension spring 11 pulls the sliding disk 31 to reset, the sliding disk 31 drives the limit post 10 to move downward. At the same time, the limit post 10 pushes the sealing plate 91 downward, and then drives the folding tube 16 to expand and reset. When the folding tube 16 expands and resets, a negative pressure is formed in the inner cavity to pump the one-way valve 17 to turn over and open. At the same time, the injection molding liquid in the inner cavity of the feeding pipe 18 is extracted into the inner cavity of the folding tube 16. When the sealing plate 91 squeezes the folding tube 16, the injection molding liquid in the inner cavity of the folding tube 16 is discharged for pouring and producing screw hardware plastic parts;

[0057] After the processing and injection molding of the screw hardware plastic parts are completed, the rotating injection molding disk 4 is continuously driven to rotate, and the rotating injection molding disk 4 drives the processed screw hardware plastic parts to move synchronously. After the rotating injection molding disk 4 drives the semi-circular slider 51 to move to the fixed plate 25, the semi-circular slider 51 will slide into the semi-circular chute of the fixed plate 25. At the same time, the semi-circular slider 51 moves upward along the surface of the semi-circular chute, and then pushes the T-shaped sliding column 54 to squeeze the material discharging spring 53 to move upward. Furthermore, the T-shaped sliding column 54 pushes the screw hardware part 29 in the inner cavity of the limiting groove 55, and the screw hardware part 29 pushes the injection-molded plastic part out of the injection molding groove 6, so as to facilitate the collection of the processed screw hardware plastic parts. After the semi-circular slider 51 slides out of the semi-circular chute, the material discharging spring 53 will rebound the semi-circular slider 51, and the semi-circular slider 51 drives the T-shaped sliding column 54 to move downward for resetting. Then, the screw hardware part 29 is installed into the inner cavity of the limiting groove 55 again. At the same time, the first spring 57 in the inner cavity of the first chute 56 bounces up the abutting block 58, and the abutting block 58 presses the screw hardware part 29 in the inner cavity of the limiting groove 55 to keep it in a vertical state, preventing the screw hardware part from tilting after the plastic part is injection-molded.
