Description

Technical Field

[0001] The present invention relates to the technical field of toy injection molding, and particularly to a plastic toy injection molding device capable of rapid cooling. Background Technique

[0002] Toy injection molding is a manufacturing process in which molten plastic is injected into a mold cavity and then cooled and solidified to form a toy product. Its core lies in precisely shaping plastic materials using high temperature and pressure, and it is widely used in the production of various toys such as building blocks, dolls, and models. Since different toys require different molds, the mold needs to be designed before toy production. In the actual design process, due to the different shapes and materials of the toys, the design of the ejection mechanism is also different. Moreover, the design of the cooling water channels in the mold needs to take into account the ejection mechanism and the shape of the toy. Therefore, it is difficult to significantly increase the cooling effect of the equipment on the toy during production simply through the design of the water channels.

[0003] In addition, the production of existing toys requires cooling to a certain stage before demolding to avoid problems such as difficult demolding and deformation of the toys due to excessive temperature. However, in actual use, molten plastic needs to be repeatedly injected into the opposite sides of the stationary mold and the moving mold. During long-term use, the surface temperature of their opposite sides is difficult to drop rapidly, and there may be situations where the toy is difficult to demold or deformed after demolding due to a slow rate of temperature decrease.

Detailed implementation mode

[0018] 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 creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-11 , the present invention provides a technical solution: a plastic toy injection molding device capable of rapid cooling, including an injection mold body 1, a fixed base 2 is arranged on one side of the injection mold body 1, and a movable block 3 is movably arranged on the upper side of the fixed base 2; The height adjustment mechanism 4 includes an adjusting screw 404 and an adjusting screw sleeve 405. The adjusting screw 404 is movably arranged on the fixed base 2. The adjusting screw sleeve 405 is fixedly installed at the center position of the movable block 3. The adjusting screw 404 is installed on the adjusting screw sleeve 405 through a thread. The driving mechanism 5 includes a limit frame 501, a first mounting block 502 and a second mounting block 505. The limit frame 501 is fixedly mounted on the movable block 3, and the first mounting block 502 and the second mounting block 505 are movably mounted in the limit frame 501; The cooling mechanism 6 includes a ventilation vertical pipe 601, a ventilation horizontal pipe 602 and an air nozzle 603. There are two groups of ventilation vertical pipes 601, and a ventilation horizontal pipe 602 is fixedly installed in an array between the ventilation vertical pipes 601. The air nozzles 603 are installed in an array on both sides of the ventilation horizontal pipe 602. The receiving mechanism 7 includes a receiving frame 701 and universal wheels 704. The receiving frame 701 is arranged on one side of the fixed base 2, and the universal wheels 704 are arranged in an array on the lower side of the receiving frame 701. The device cools the opposite sides of the static mold and the dynamic mold on the injection mold body 1 with the help of the external cooling mechanism 6. The cooling process is arranged in the mold opening process, which not only allows the toy to be cooled faster, but also takes away the heat accumulated on the static mold and the dynamic mold of the injection mold body 1, thereby improving the functionality of the device.

[0020] When the cooling mechanism 6 is reset, it can also take away the molded toy by clamping, further enhancing the functionality of the device. Moreover, according to the difference in the toy type, the part taken away is also different.

[0021] like Figure 5 As shown, if the toy is a small spliced ​​disc, the ejection mechanism can shake the disc off the injection molding bracket during ejection. However, although such small toys can be demolded from the injection molding bracket by vibration, due to the uncertainty of the vibration direction, sometimes the disc will be shaken to the upper side of the movable mold, which may hinder the movement of the movable mold. Under the action of the cooling mechanism 6, the disc is affected by the wind pressure and it is difficult to vibrate to the upper side of the movable mold, which improves the stability of the equipment. For such small toys, the cooling mechanism 6 takes out the injection molding bracket when resetting.

[0022] For larger or special-shaped toys, it is difficult to realize automatic separation by the design of the ejection mechanism. Therefore, for this type of toys, what is taken out when the cooling mechanism 6 is reset is the injection molding support and the toys attached thereto.

[0023] Further, the height adjustment mechanism 4 further includes guide rods 401, guide grooves 402, connecting rods 403 and adjusting screws 404. Four groups of guide rods 401 are fixedly installed on the upper side of the fixed base 2, and four groups of guide grooves 402 are formed on the movable block 3. The guide rods 401 are movably inserted into the guide grooves 402. The upper side of the fixed base 2 is rotatably installed with a connecting rod 403 through a bearing, and the upper end of the connecting rod 403 is fixedly installed with an adjusting screw 404. The schematic diagram of this structure is Figure 7 . The height of the movable block 3 is adjusted by the threaded cooperation between the adjusting screw 404 and the adjusting nut 405. When the adjusting screw 404 is rotated, through the threaded drive with the adjusting nut 405, the movable block 3 is driven to rise or fall, so that the position of the cooling mechanism 6 is accurately adapted to the positions of the stationary mold and the moving mold of the injection mold body 1.

[0024] This design has the following advantages: Optimized cooling effect: By adjusting the height of the cooling mechanism 6, the air outlet 603 of the ventilation cross pipe 602 can be kept at the best distance from the opposite sides of the stationary mold and the moving mold, significantly increasing the cold air contact area and improving the cooling efficiency.

[0025] Improved motion stability: Avoid interference between the cooling mechanism 6 and the stationary mold and the moving mold of the injection mold body 1, ensuring the safety and stability of the equipment operation.

[0026] Enhanced equipment adaptability: Since the cooling mechanism 6 and the injection mold body 1 adopt a separated design, the height adjustment mechanism 4 can quickly adjust the height according to different models of the injection mold body 1, realizing the compatible adaptation of the equipment to multiple molds; Further, the height adjustment mechanism 4 includes a first movable groove 406, a movable circular block 407, a rotating handle 408, a limiting column 409, a first limiting hole 410, a return spring 411, a limiting ratchet 412 and a ratchet groove 413. The first movable grooves 406 are arrayed on the connecting rod 403. A movable circular block 407 is movably sleeved inside the connecting rod 403. The outer sides of the movable circular block 407 are fixedly installed with rotating handles 408 in an array. A limiting column 409 is fixedly installed inside the connecting rod 403. A first limiting hole 410 is formed at the central position of the movable circular block 407. The movable circular block 407 is movably sleeved on the limiting column 409 through the first limiting hole 410. A return spring 411 is sleeved on the limiting column 409. One end of the return spring 411 abuts against the movable circular block 407. A limiting ratchet 412 is fixedly installed on the lower side of the movable circular block 407. A ratchet groove 413 is formed on the upper side of the fixed base 2. The limiting ratchet 412 is engaged in the ratchet groove 413. The schematic diagram of this equipment is Figure 7 and Figure 11, this structure enables the movable circular block 407 to assist the adjusting screw 404 in rotating, and it can itself move in the vertical direction. On the one hand, through this lifting, the user can hold the rotating handle 408 more comfortably to rotate, thereby increasing the user's comfort. On the other hand, the rotation of the movable circular block 407 can be limited by the engagement between the limiting ratchet 412 and the ratchet groove 413, so that the locking of the lifting of the movable block 3 has higher stability and higher resistance to the vibration generated during movement, further increasing the stability of the equipment during use; Furthermore, the driving mechanism 5 further includes a limiting frame 501, a first mounting block 502, a rack 503, a limiting strip 504, a second mounting block 505, a driving motor 506, a driving gear 507, a first mounting groove 508, a roller 509, a limiting block 510 and a ball 511. The upper sides of the first mounting block 502 and the second mounting block 505 are fixedly installed with a rack 503, and the lower sides of the first mounting block 502 and the second mounting block 505 are fixedly installed with a limiting strip 504. The upper end of the limiting frame 501 is fixedly installed with a driving motor 506, and the output shaft of the driving motor 506 is fixedly installed with a driving gear 507. The driving gear 507 meshes with the rack 503. The lower side of the limiting frame 501 is provided with a first mounting groove 508, and a plurality of rollers 509 are rotationally installed in the first mounting groove 508 in an array. The lower side of the limiting strip 504 is in contact with the rollers 509. Two groups of limiting blocks 510 are fixedly installed on the upper side of the first mounting groove 508. The limiting blocks 510 are engaged on both sides of the limiting strip 504. The lower sides and the opposite sides of the limiting blocks 510 are rotationally installed with balls 511, and the balls 511 are in contact with the surface of the limiting strip 504. The schematic diagram of this structure is Figure 4 , Figure 6 and Figure 10 , and what this structure realizes is the horizontal movement of the frame with the first mounting block 502, the rack 503, the limiting strip 504 and the second mounting block 505 as the main body. This kind of movement is in active cooperation with the moving die. That is, when the moving die and the stationary die are separated, the driving mechanism 5 drives its frame to be inserted between the moving and stationary dies, and the cooling mechanism 6 cools the opposite side. When the moving and stationary dies are combined, it resets. This movement mode will not interfere with the movement mode of the moving and stationary dies. And considering the installation space and installation stability, this driving method requires less installation space and has higher stability than the driving method through an electric telescopic rod in this movement mode. In this structure, the main stress part of its frame is the limiting strip 504, so rollers 509 and balls 511 are arranged on all the stress surfaces of the limiting strip 504 to cooperate with the limiting strip 504 to move, thereby reducing the resistance of the frame during movement and further increasing the stability of the equipment during use; Furthermore, the cooling mechanism 6 further includes ventilation vertical pipes 601, ventilation horizontal pipes 602, air injection nozzles 603, conical insertion pipes 604, sealing rubber rings 605, conical slots 606, fixing plates 607, second installation grooves 608, second limiting holes 609, limiting sleeve nuts 610 and limiting screw rods 611. Conical insertion pipes 604 are fixedly installed on both the upper and lower sides of a group of ventilation vertical pipes 601. The conical insertion pipes 604 communicate with the ventilation vertical pipes 601. Sealing rubber rings 605 are fixedly installed on the conical insertion pipes 604. Conical slots 606 are formed on both the upper and lower sides of the second installation block 505. The conical insertion pipes 604 are inserted into the conical slots 606. Fixing plates 607 are fixedly installed on a group of ventilation vertical pipes 601. A second installation groove 608 is formed at the central position of the second installation block 505. The fixing plates 607 are inserted into the second installation groove 608. Two groups of second limiting holes 609 are formed on the fixing plates 607. Two groups of limiting sleeve nuts 610 are fixedly installed on the second installation block 505. The positions of the second limiting holes 609 correspond to the positions of the limiting sleeve nuts 610. Two groups of limiting screw rods 611 are movably inserted into the second installation block 505. The limiting screw rods 611 are inserted into the second limiting holes 609 and are threadedly installed in the limiting sleeve nuts 610. The schematic diagram of this structure is Figure 4 . The ventilation vertical pipes 601 and ventilation horizontal pipes 602 of the cooling mechanism 6 adopt a detachable design, and their layout can be flexibly adjusted according to the shape of the mold. Figure 4 The layout of the ventilation horizontal pipes 602 shown is a general structure and is applicable to conventional molds. For three-dimensional special-shaped toys with a large surface area, such as dinosaur toys, ventilation vertical pipes 601, ventilation horizontal pipes 602 and air injection nozzle 603 components matching the shape of the mold can be customized to achieve a more uniform heat dissipation effect. Therefore, when replacing the injection mold, the corresponding cooling components need to be replaced synchronously.

[0027] The connection between the ventilation vertical pipes 601 and the frame of the driving mechanism 5 adopts an interference fit between the conical insertion pipes 604 and the conical slots 606. Combined with the sealing effect of the sealing rubber rings 605, the airtightness of the air path system is ensured; Further, the cooling mechanism 6 further includes a first limiting plate 612, a flexible pad 613, a connecting air duct 614, a ventilation groove 615, a flexible ventilation duct 616 and an air pump 617. A first limiting plate 612 is fixedly installed on one side of a group of ventilation vertical pipes 601. Flexible pads 613 are fixedly installed on the upper and lower sides of the first limiting plate 612. The flexible pads 613 are abutted against the rack 503 and the limiting strip 504. Two groups of connecting air ducts 614 are fixedly installed on the second mounting block 505. The connecting air ducts 614 communicate with the conical socket 606. A ventilation groove 615 is formed in the first mounting block 502. The ventilation groove 615 communicates with the connecting air duct 614. A flexible ventilation duct 616 is fixedly installed on the first mounting block 502. One end of the flexible ventilation duct 616 communicates with the ventilation groove 615. An air pump 617 is arranged on one side of the fixed base 2. The other end of the flexible ventilation duct 616 is communicated with the air outlet of the air pump 617. The schematic diagram of this structure is Figure 4 . The cooling mechanism 6 realizes the through connection of the air path through the interference fit of the conical insertion pipe 604 and the conical socket 606 of the frame of the driving mechanism 5. The frame of the driving mechanism 5 is communicated with the air outlet of the air pump 617 through the flexible ventilation duct 616. Since the flexible ventilation duct 616 has the characteristic of being bendable, it can adapt to the reciprocating movement of the frame of the driving mechanism 5 and ensure that the operation stability of the equipment is not affected during the air flow transmission; Further, the lengths of the ventilation vertical pipes 601 and the ventilation horizontal pipes 602 are adapted to the length and width of the mold on the injection mold body 1. The ventilation horizontal pipe 602 is located at the central position between the stationary mold and the moving mold on the injection mold body 1. The surface of the air outlet 603 is an arc surface and is provided with micropores in an array. The schematic diagram of this structure is Figure 5 and Figure 9 . First, the lengths of the ventilation vertical pipes 601 and the ventilation horizontal pipes 602 are adapted to the shapes of the stationary mold and the moving mold, so that the cooling air surface can cool the surfaces of the stationary mold and the moving mold more comprehensively to the greatest extent, and the guide posts arranged between the stationary mold and the moving mold on the injection mold body 1 can be avoided, so that there will be no movement interference when the equipment moves. The air outlet 603 is in the shape of a lotus flower, and the cooling air can be divided into multi-directional air flows through the micropores, so that the cooling on the opposite sides of the stationary mold and the moving mold is more uniform; Further, the receiving mechanism 7 further includes a receiving frame 701, a clamping groove 702, a second limiting plate 703, universal wheels 704 and finger grooves 705. A clamping groove 702 is formed on one side of the receiving frame 701. The shape of the clamping groove 702 is adapted to the shape of one side of the fixed base 2. The length of the receiving frame 701 is adapted to the length of the fixed base 2. A second limiting plate 703 is fixedly installed on the receiving frame 701. The distance between the second limiting plate 703 and the inner wall of the receiving frame 701 is adapted to the width of the fixed base 2. Two groups of finger grooves 705 are formed on the lower side of the movable block 3. The schematic diagram of this structure is Figure 7 and Figure 8, this structure enables the receiving frame 701 to receive injection-molded toys or injection-molded brackets, and also has the function of carrying the fixed base 2 and the parts installed on the fixed base 2, so that the fixed base 2 and the parts installed on the fixed base 2 can be conveniently moved through the receiving frame 701 and the universal wheels 704, increasing the convenience during equipment movement and also increasing the functionality of the receiving frame 701 during use; Furthermore, an installation frame 8 is fixedly installed between the two middle ventilation cross-tubes 602. A telescopic motor 9 is fixedly installed inside the installation frame 8. A pressing block 10 is fixedly installed on the output shaft of the telescopic motor 9. A limiting ring 11 is fixedly installed at the central position of the two middle ventilation cross-tubes 602. A second movable groove 12 is opened on one side of the limiting ring 11. The pressing block 10 is movably inserted into the second movable groove 12. The schematic diagram of this structure is Figure 9 , during the process of toy injection molding, the injection-molded toy often adheres to the injection-molded bracket. The injection-molded bracket is the product after the molten plastic solidifies in the mold runner. There is often a protruding handle at the central position of the injection-molded bracket, that is, the product after the molten plastic at the connection between the injection port and the mold solidifies. When this structure is in use, the handle of the injection-molded bracket is opposite to the position of the limiting ring 11. When the ejection mechanism of the injection mold body 1 operates, the injection-molded toy is ejected, and the handle of the injection-molded bracket is inserted into the limiting ring 11. The pressing block 10 can be pressed against the handle of the injection-molded bracket under the action of the telescopic motor 9, so that the bracket can be taken away when the cooling mechanism 6 moves, increasing the functionality during equipment use; Furthermore, two photoelectric emitters 13 and photoelectric sensors 14 are fixedly installed on the upper side of the limiting frame 501. The positions of the photoelectric emitter 13 and the photoelectric sensor 14 are opposite. The photoelectric sensor 14 is fixedly installed on the front and rear sides of the limiting frame 501. An infrared sensor 15 is fixedly installed on the ventilation cross-tube 602. The schematic diagram of this structure is Figure 3 , Figure 4 and Figure 6 , taking Figure 3 as the front view, during the process of the injection mold body 1 closing the mold, the frame of the driving mechanism 5 is in Figure 3The position is such that the light emitted by the photoelectric emitter 13 on its front side can be sensed by the photoelectric sensor 14, while the photoelectric sensor 14 on the rear side cannot sense the light emitted by the corresponding photoelectric emitter 13 due to the blockage of the rack 503. When the injection mold body 1 is opened, the frame of the driving mechanism 5 is located between the moving and stationary molds. At this time, the light emitted by the front-side photoelectric emitter 13 is blocked, while the light emitted by the rear-side photoelectric emitter 13 is not blocked by the rack 503 and is sensed by the photoelectric sensor 14. Through these two sets of photoelectric emitters 13 and photoelectric sensors 14, the position state of the frame of the driving mechanism 5 can be clearly judged. That is, if the front-side photoelectric sensor 14 senses and the rear-side photoelectric sensor 14 does not, the frame of the driving mechanism 5 is in the retracted state; if the front-side photoelectric sensor 14 does not sense and the rear-side photoelectric sensor 14 senses, the frame of the driving mechanism 5 is between the moving and stationary molds; if neither of the two sets of photoelectric sensors 14 senses intermittently, the frame of the driving mechanism 5 is in the moving state; if neither of the two sets of photoelectric sensors 14 senses for a long time, the frame of the driving mechanism 5 is in the stopped state or a faulty state; if both sets of photoelectric sensors 14 sense, the frame of the driving mechanism 5 has been disassembled. By observing the interval between the sensations of the two sets of photoelectric sensors 14, the movement speed of the frame of the driving mechanism 5 can be observed. Furthermore, the movement speed of the frame of the driving mechanism 5 can be controlled by adjusting the forward and reverse rotation speeds of the driving motor 506, so that the movement speed of the frame of the driving mechanism 5 can be coordinated with the speed of the injection mold body 1, avoiding the situation where the frame of the driving mechanism 5 is squeezed by the mold of the injection mold body 1. The infrared sensor 15 can sense the temperature on the opposite side of the moving and stationary molds.

[0028] Working principle: When the present invention is in use, the driving mechanism 5 is driven as the molds on the injection mold body 1 are opened and closed. When the moving and stationary molds are opened, the output shaft of the driving motor 506 rotates forward, driving the driving gear 507 to rotate. The rotation of the driving gear 507 drives the frame of the driving mechanism 5 to move between the moving and stationary molds through meshing with the rack 503, so that the ventilation vertical pipe 601 and the ventilation horizontal pipe 602 are located between the moving and stationary molds. The air flow generated by the air pump 617 enters the ventilation vertical pipe 601 and the ventilation horizontal pipe 602 through the flexible ventilation pipe 616 and is ejected through the air ejection port 603, thereby cooling the opposite sides of the moving and stationary molds and the plastic toy. Then the plastic toy is ejected by the ejection mechanism. At this time, the handle on the injection support is inserted into the limit ring 11, and the pressing block 10 on the output shaft of the telescopic motor 9 presses the handle of the injection support so that the handle is pressed in the limit ring 11. Then the output shaft of the driving motor 506 rotates in reverse, driving the frame of the driving mechanism 5 back to its original position, and the output shaft of the telescopic motor 9 resets. The injection frame falls into the receiving frame 701 under the action of gravity.

[0029] When adjusting the height of the movable block 3, hold the rotating handle 408 and lift the movable circular block 407. At this time, the movable circular block 407 moves along the limit post 409 and compresses the return spring 411. The limit ratchet 412 disengages from the ratchet groove 413 so that the movable circular block 407 can rotate. Then, rotating the rotating handle 408 can drive the connecting rod 403 and the adjusting screw 404 to rotate. Through the thread action between the adjusting screw 404 and the adjusting nut 405, the movable block 3 can be driven to move up and down. During the up and down movement, the guide rod 401 moves within the guide groove 402. After the adjustment is completed, release the rotating handle 408. Under the action of the return of the return spring 411, the limit ratchet 412 is re-engaged in the ratchet groove 413.

[0030] When disassembling the ventilation vertical pipe 601 and the ventilation horizontal pipe 602, unscrew the limit screw 611 from the limit nut 610, pull out the limit screw 611 from the second limit hole 609, and then hold the first limit plate 612 and pull it. At this time, the fixed plate 607 is pulled out from the second installation groove 608, and the tapered insertion tube 604 is pulled out from the tapered insertion slot 606 to complete the disassembly. The installation is the same in principle.

[0031] When moving the fixed base 2 and the parts on the fixed base 2, lift the movable block 3 through the finger groove 705 so that the fixed base 2 falls into the receiving frame 701 and fits with the edges of the receiving frame 701 and the second limit plate 703, enabling the fixed base 2 etc. to be moved conveniently.
