Description

Technical Field

[0002] Hardware plastic refers to adding metal structural parts or accessories to plastic products to enhance their strength and practicality, while also increasing their aesthetics and texture. They are widely used in daily life and various industrial production. For example, screw hardware plastic parts are based on screws, and plastic parts are injection molded at one end of the screw using processing and molding equipment, so that the screws can be easily twisted for disassembly and use without using a screwdriver, thereby improving the flexibility of the hardware.

[0003] A patent with publication number CN116714161B discloses a rapid processing and molding equipment for hardware and plastic parts. The patent detects the movement of the punch head by arranging a photoelectric sensor on the bracket, so that it can determine whether the punch head has completed punching, and then transmits the signal to the single-chip microcomputer inside the electric control box. The single-chip microcomputer controls the motor to start rotating so that the punching groove at the top of the turntable is located directly below the punch head, so that the punching groove rotates, which facilitates the punching machine to work again. This structure does not require personnel to frequently change products for stamping, and can realize continuous automatic processing of the equipment. The operator can change the product on the side away from the punch head, avoiding the problem of safety hazards when working under the punching machine.

DETAILED DESCRIPTION

[0021] 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.

[0022] Embodiment 1 like Figures 1 to 9 As shown, a hardware plastic parts rapid processing and molding device described in an embodiment of the present invention comprises 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 molding disk 4 is rotatably connected to the inner cavity of the rotating groove 30, the lower end of the rotating injection molding disk 4 is located outside the inner cavity of the rotating groove 30 and is fixedly connected to a gear ring 20, the rotating injection molding 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, one side of the lower end surface of the support plate 8 is fixedly connected to a folding tube 16, and a sealing injection molding component 9 is arranged at the lower end of the folding tube 16; The sealing injection molding assembly 9 includes a sealing plate 91 fixedly connected to the lower end of the folding tube 16, a shaping block 92 is fixedly connected to the lower end surface of the sealing plate 91, and an injection molding port 97 is opened on the lower end surface of the shaping block 92; A plurality of injection molding grooves 6 are evenly formed on the upper end surface of the rotating injection molding disk 4 , and the inner cavities of the plurality of injection molding grooves 6 are used for installing screw hardware 29 .

[0023] Specifically, in the prior art, when manufacturing screw hardware plastic parts, the screw hardware parts are usually placed in an injection mold, and then the injection molding liquid is poured into the injection mold by using an injection molding assembly, and the screw hardware plastic parts are demolded after the injection molding liquid is cooled, and then the screw hardware plastic parts are placed in the injection mold again in sequence for injection molding to produce the screw hardware plastic parts. However, since the injection molding liquid cannot be poured automatically and the amount of the injection molding liquid cannot be accurately controlled at the same time, the pouring operation needs to be repeated multiple times, resulting in the plastic part of the screw hardware plastic parts having distinct layers, and the hardness and other quality not meeting the standards, thereby reducing the production efficiency of the screw hardware plastic parts; The present invention uses manual or mechanical arms to vertically place the screw hardware 29 in the injection molding groove 6, and then drives the rotating injection molding disk 4 to rotate. After the rotating injection molding disk 4 drives the screw hardware 29 to move below the sealed injection molding assembly 9, the electric push rod 7 is started to drive the support plate 8 to move downward, and then the support plate 8 drives the folding tube 16 to move downward, and at the same time drives the sealing plate 91 to move synchronously, so that the sealing plate 91 drives the shaping block 92 to slide into the injection molding groove 6, and the sealing plate 91 seals the injection molding groove 6, and as The support plate 8 continues to move downward, and the support plate 8 will cooperate with the sealing plate 91 to squeeze the folding tube 16 for folding, and at the same time, the folding tube 16 squeezes the injection liquid in the inner cavity, and injects it into the injection groove 6 through the injection port 97 to process the screw hardware plastic parts. After the injection molding is completed, the electric push rod 7 is started to drive the support plate 8 to move upward and reset, and then the injection molding disk 4 is driven to rotate again, and the support plate 8 is driven downward again to perform injection molding, so that the screw hardware plastic parts can be processed and manufactured in a cycle, thereby solving the above-mentioned problem.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, two second slide grooves 93 are symmetrically opened on the inner wall of the injection port 97, and second springs 94 are fixedly connected to the bottom of the inner cavity of the two second slide grooves 93, one end of one of the second springs 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 block 96, and the conical sealing block 96 cooperates with the U-shaped sealing block 95 to seal the injection port 97 and cut off the injection liquid.

[0025] like Figure 1 , Figure 2 and Fig. 9 As shown, two limit columns 10 are slidably connected to one side of the upper end surface of the support plate 8, and sliding plates 31 are slidably installed on the outside of the two limit columns 10. A tension spring 11 is fixedly connected to the lower end surface of the sliding plate 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.

[0026] Specifically, when the screw hardware plastic parts are injection molded, the electric push rod 7 is started to drive the support plate 8 to move downward, and the support plate 8 uses the tension spring 11 to drive the limit column 10 to move downward. At the same time, the limit column 10 drives the sealing plate 91 to push the shaping block 92 to move 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 will cooperate with the sealing plate 91 to push the limit column 10 to move upward. At the same time, the limit column 10 cooperates with the sliding plate 31 to pull the tension spring 11 to expand, thereby squeezing the folding tube 16 to fold, and at the same time, the folding tube 16 squeezes the injection liquid in the inner cavity, and the injection liquid squeezes the conical sealing block 96 and the U-shaped sealing block 95 to slide into the inner cavity of the second slide groove 93, and then is injected into the injection groove 6 through the injection port 97 to process the screw hardware plastic parts. After the injection liquid is poured into the injection groove 6, the conical sealing block 96 and the U-shaped sealing block are bounced up by the second spring 94. 95, so that the conical sealing block 96 cooperates with the U-shaped sealing block 95 to cut off the cooled injection molding liquid, so as to facilitate the disassembly and processing of the screw hardware plastic parts. When it is necessary to process the screw hardware plastic parts to be processed, the sliding plate 31 is removed and slid to adjust the position outside the limit column 10, and then the sliding plate 31 is fixed to the outside of the limit column 10 by the fastening bolt, and then the tension of the tension spring 11 can be used to push the sealing plate 91 to move downward. At the same time, the sealing plate 91 drives the folding tube 16 to expand, and the size of the inner cavity of the folding tube 16 is adjusted, thereby increasing the storage capacity of the injection molding liquid, so as to adjust the amount of injection molding liquid required for molding according to the screw hardware plastic parts to be processed, thereby solving the problem that the existing hardware plastic parts rapid processing molding equipment cannot accurately control the injection amount of the injection molding liquid, resulting in the need to repeat the injection operation for many times, resulting in the plastic parts of the screw hardware plastic parts having distinct layers and the hardness and other quality not meeting the standards, thereby reducing the production efficiency of the screw hardware plastic parts.

[0027] like Figure 4 , Figure 5 and Fig. 9 As shown, a heating tank 13 is installed on one side of the upper end surface of the support plate 8, and a feeding pipe 18 is fixedly connected to the lower end of the heating tank 13. One end of the feeding pipe 18 is fixedly connected to the support plate 8 and is connected to the inner cavity of the folding tube 16. A one-way valve 17 is provided in the inner cavity of the support plate 8, and the one-way valve 17 can only be flipped open toward the inner cavity of the folding tube 16.

[0028] like Figure 4 , Figure 5 and Fig. 9As shown, a pipe heater 12 is installed on the upper end surface of the support plate 8, and the pipe heater 12 is installed with the feeding pipe 18, which is used to heat the feeding pipe 18 to improve the fluidity of the injection liquid. A wire 14 is electrically connected to the upper end of the pipe heater 12, and one end of the wire 14 is electrically connected to the heating tank 13. A support plate 15 is fixedly connected to the piston rod end of the electric push rod 7, and the support plate 15 is fixedly installed with the support plate 8.

[0029] Specifically, when the screw hardware plastic parts are injection molded, the plastic is melted by starting the heating tank 13, and then the injection liquid is transported into the folding tube 16 through the feeding tube 18. During the start-up process of the heating tank 13, the pipe heater 12 is powered by the wire 14, so that the pipe heater 12 can heat and keep the feeding tube 18 warm, thereby preventing the injection liquid from cooling and hardening during the process of being transported into the folding tube 16 through the feeding tube 18. When the tension spring 11 pulls the sliding plate 31 to reset, the sliding plate 31 will drive the limit column 10 to move downward, and at the same time, the limit column 10 pushes The sealing plate 91 moves downward, thereby driving the folding tube 16 to expand and reset. When the folding tube 16 is expanded and reset, a negative pressure is formed in the inner cavity to pull the one-way valve 17 to flip and open, and at the same time, the injection liquid in the inner cavity of the feeding tube 18 is drawn into the inner cavity of the folding tube 16. When the sealing plate 91 squeezes the folding tube 16, the injection liquid in the inner cavity of the folding tube 16 is discharged for injection production of screw hardware plastic parts, thereby solving the problem of the inability of existing hardware and plastic parts rapid processing equipment to automatically and quantitatively extract injection liquid and inject injection liquid into the injection molding groove, resulting in the problem of hardware and plastic parts production and processing efficiency.

[0031] like Figure 3 , Figure 4 , Figure 6 and Fig. 9 As shown, a servo motor 19 is installed in the inner cavity of the circular protective cabinet 2. The output shaft end of the servo motor 19 passes through the circular protective cabinet 2 and is fixedly connected to a gear plate 21 in the inner cavity of the rotating groove 30. The gear plate 21 is meshed with the gear ring 20 to drive the rotating injection molding disk 4 to rotate.

[0032] Specifically, the screw hardware 29 is placed vertically in the injection molding groove 6 by manual or mechanical arm, and then the electric push rod 7 is started to drive the rotating injection molding disk 4 to rotate, and the rotating injection molding disk 4 drives the screw hardware 29 to move. After the rotating injection molding disk 4 drives the screw hardware 29 to rotate to the bottom of the sealed injection molding component 9, the trigger button 28 is popped up by the elastic member 27 in the inner cavity of the storage groove 26, and the trigger button 28 presses the trigger 32 to start the electric push rod 7, and then the electric push rod 7 drives the support plate 8 to move downward, and at the same time drives the sealing plate 91 synchronously. Move, so that the sealing plate 91 drives the shaping block 92 to slide into 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 will cooperate with the sealing plate 91 to squeeze the folding tube 16 for folding, and at the same time, the folding tube 16 squeezes the injection liquid in the inner cavity and injects it into the injection molding groove 6 through the injection port 97 to process the screw hardware plastic parts, thereby improving the automation degree of the hardware and plastic parts rapid processing and molding equipment, so that it can cyclically manufacture and process screw hardware and plastic parts, and improve the production efficiency of screw hardware and plastic parts.

[0033] like Figure 1 , Figure 3 and Fig. 9 As shown, a groove 23 is provided on one side of the circular protective cabinet 2, a threaded rod 24 is rotatably connected to the inner cavity of the groove 23, a fixed plate 25 is threadedly connected to the outer surface of the threaded rod 24, and the fixed plate 25 is slidably connected to the inner cavity of the groove 23, a semicircular groove is provided on the upper end surface of the fixed plate 25, and balls are evenly arranged in the inner cavity of the semicircular groove.

[0034] Specifically, when processing and manufacturing screw hardware and plastic parts of different lengths, the threaded rod 24 is driven to rotate, and the threaded rod 24 thread transmission fixing plate 25 slides in the inner cavity of the groove 23, and then the fixing plate 25 moves upward to adjust the position, so that the fixing plate 25 can use the semicircular slide groove to better push the semicircular slider 51 to move upward, and the semicircular slider 51 pushes the T-shaped slide column 54 to squeeze the ejection spring 53 to move upward, and then the T-shaped slide column 54 pushes the screw hardware 29 in the inner cavity of the limiting groove 55, and the screw hardware 29 pushes the injection molded plastic parts to slide out of the injection groove 6, so as to facilitate the collection of the processed screw hardware and plastic parts, and improve the recycling efficiency and convenience of the screw hardware and plastic parts.

[0035] like Figure 1 , Figure 4 , Figure 6 and Figure 7As shown, a material return assembly 5 is provided on the lower end surface of the rotating injection molding disk 4, and the material return assembly 5 includes a limiting groove 55 opened at the bottom of the inner cavity of the injection molding groove 6, a plurality of fixed cylinders 52 are fixedly connected to the lower end surface of the rotating injection molding disk 4, and the fixed cylinders 52 are connected to the inner cavity of the limiting groove 55, a plurality of material return springs 53 are fixedly connected to the lower end surface of the rotating injection molding disk 4, and a semicircular slider 51 is fixedly connected to one end of the plurality of material return springs 53, a T-shaped sliding column 54 is installed in the upper end of the semicircular slider 51, and the T-shaped sliding column 54 is slidably connected to the inner cavity of the fixed cylinder 52, so as to push the screw hardware 29 for material return and recovery.

[0036] like Figure 4 , Figure 6 and Figure 7 As shown, two first slide grooves 56 are symmetrically opened on the inner wall of the limit groove 55, and the bottom of the inner cavity of the two first slide grooves 56 are fixedly connected to the first spring 57, and one end of the first spring 57 is fixedly connected to a stop block 58, and the stop block 58 is used to abut the positioning screw hardware 29 and seal the inner cavity of the limit groove 55.

[0037] Specifically, after the injection molding of the screw hardware plastic parts is 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 semicircular slider 51 to move to the fixed plate 25, the semicircular slider 51 will slide into the semicircular slide groove of the fixed plate 25, and at the same time, the semicircular slider 51 moves upward along the surface of the semicircular slide groove, and then pushes the T-shaped slide post 54 to squeeze the ejection spring 53 to move upward, so that the T-shaped slide post 54 pushes the screw hardware 29 in the inner cavity of the limiting groove 55, and the screw hardware 29 pushes the injection molded plastic parts to slide out of the injection molding groove 6, so as to facilitate the collection of the processed screw hardware plastic parts, and after the semicircular slider 51 slides out of the semicircular slide groove, the ejection spring 53 will rebound the semicircular slider 51, and make The semicircular slider 51 drives the T-shaped slider 54 to move downward for reset, and then the screw hardware 29 is installed in the inner cavity of the limiting groove 55 again. At the same time, the first spring 57 in the inner cavity of the first slide groove 56 is used to bounce the stop block 58, and the stop block 58 presses the screw hardware 29 in the inner cavity of the limiting groove 55 to keep it in a vertical state, thereby preventing the screw hardware part from tilting after the plastic part is injection molded. This solves the problem that the existing hardware and plastic parts rapid processing and molding equipment does not clamp and position the screw hardware before processing the plastic part to ensure its vertical state, resulting in the screw hardware part being tilted after the plastic part is processed and injection molded, causing the quality of the processed hardware and plastic parts to be substandard and unable to be used.

[0038] Working principle: 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 uses the tension spring 11 to drive the limit column 10 to move downward, and at the same time, the limit column 10 drives the sealing plate 91 to push the shaping block 92 to move 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 will cooperate with the sealing plate 91 to push the limit column 10 to move upward. At the same time, the limit column 10 cooperates with the sliding plate 31 to pull the tension spring 11 to expand, thereby squeezing the folding tube 16 to fold, and at the same time, the folding tube 16 squeezes the injection liquid in the inner cavity, and the injection liquid squeezes the conical sealing block 96 and the U-shaped sealing block 95 into the inner cavity of the second slide groove 93, and then is injected into the injection groove 6 through the injection port 97 for folding. Processing screw hardware plastic parts, after the injection molding liquid is poured into the injection molding groove 6, the conical sealing block 96 and the U-shaped sealing block 95 are bounced up by the second spring 94, so that the conical sealing block 96 cooperates with the U-shaped sealing block 95 to cut off the cooled injection molding liquid, so as to facilitate the disassembly of the processed screw hardware plastic parts. When it is necessary to process the screw hardware plastic parts to be processed, the sliding plate 31 is removed and slidably adjusted on the outside of the limit column 10, and then the sliding plate 31 is fixed to the outside of the limit column 10 by the fastening bolt, so that the sealing plate 91 can be pushed downward by the tension of the tension spring 11, and at the same time, the sealing plate 91 drives the folding tube 16 to expand, adjusts the size of the inner cavity of the folding tube 16, and thereby increases the storage capacity of the injection molding liquid, so as to adjust the amount of the injection molding liquid required for injection molding according to the screw hardware plastic parts to be processed; When the screw hardware plastic parts are injection molded, the plastic is melted by starting the heating tank 13, and then the injection liquid is transported into the folding tube 16 through the feeding pipe 18. During the start-up process of the heating tank 13, the pipe heater 12 is powered by the wire 14, so that the pipe heater 12 heats and keeps the feeding pipe 18 warm, thereby preventing the injection liquid from cooling and hardening during the process of being transported into the folding tube 16 through the feeding pipe 18. The tension spring 11 pulls the slide plate 31 to return to the original position. When the folding tube 16 is in the position, the sliding plate 31 will drive the limiting column 10 to move downward, and the limiting column 10 will push the sealing plate 91 to move downward, and then drive the folding tube 16 to expand and reset. When the folding tube 16 is expanded and reset, the inner cavity will form a negative pressure to pull the one-way valve 17 to flip open, and at the same time, the injection liquid in the inner cavity of the feeding tube 18 is drawn into the inner cavity of the folding tube 16. When the sealing plate 91 squeezes the folding tube 16, the injection liquid in the inner cavity of the folding tube 16 will be discharged to inject and produce screw hardware plastic parts; After the screw hardware plastic parts are processed and injection molded, 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 semicircular slider 51 to move to the fixed plate 25, the semicircular slider 51 will slide into the semicircular slide groove of the fixed plate 25, and at the same time, the semicircular slider 51 moves upward along the surface of the semicircular slide groove, and then pushes the T-shaped slide post 54 to squeeze the ejection spring 53 to move upward, so that the T-shaped slide post 54 pushes the screw hardware 29 in the inner cavity of the limiting groove 55, and the screw hardware 29 pushes the injection molded plastic parts to slide. The semicircular slider 51 slides out of the injection groove 6, thereby facilitating the collection of the processed screw hardware plastic parts. After the semicircular slider 51 slides out of the semicircular slide groove, the material withdrawal spring 53 will rebound the semicircular slider 51, and make the semicircular slider 51 drive the T-shaped slide column 54 to move downward for reset, and then install the screw hardware 29 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 slide groove 56 is used to pop up the stop block 58, and the stop block 58 presses the screw hardware 29 in the inner cavity of the limiting groove 55 to keep it in a vertical state, thereby preventing the screw hardware part from tilting after the plastic part is injection molded.
