Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and more specifically, to a multi-color injection mold device for toys. Background Technology

[0002] Multi-color injection molding for toys is an advanced plastic molding process that involves injecting different colored plastic materials into the same mold in stages or simultaneously, allowing the toy to be molded in one piece into a complex structure with a colorful appearance or a combination of multiple materials. This technology is widely used in products such as building blocks, dolls, and model cars. It not only enables vibrant color combinations and gradient effects but also combines soft and hard plastics, enhancing the toy's functionality and tactile feel. Simultaneously, it reduces subsequent assembly steps, improving production efficiency and lowering costs.

[0003] In multi-color injection molding production of toys, it is usually necessary to manually change different colored plastic raw materials. This is not only inefficient, but also prone to material mixing or contamination due to operational errors, affecting product quality. Manual material changing also results in wasted time and high labor intensity, especially in production scenarios where colors are frequently changed, which severely restricts injection molding production efficiency.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, this utility model provides a multi-color injection mold device for toys, which has the following beneficial effects:

[0019] This multi-color injection molding device for toys, during injection molding, activates a servo motor, which drives a transmission worm gear to rotate. This worm gear, in turn, rotates a mounting ring plate via a rotating shaft, moving the corresponding material storage bin to the upper side of the injection molding equipment's feed hopper. Then, a corresponding drive motor activates, rotating a transmission threaded rod that lowers a transmission plate. This lowers a conical sealing block via an L-shaped connecting rod, opening the bottom opening of the material storage bin. After feeding, the transmission threaded rod reverses, raising the transmission plate so the L-shaped connecting rod and the conical sealing block seal the bottom opening of the storage bin. Repeating these steps allows for automated feeding of multiple colors of plastic raw materials, quickly and accurately delivering different colored materials into the hopper. This avoids the time and labor costs of manual material changes, reduces human intervention, lowers the risk of operational errors, and significantly improves production efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Example:

[0029] Please see Figures 1-5 A multi-color injection molding device for toys, comprising:

[0030] A support base 1 is provided, a support frame plate 2 is fixedly connected to the top of the support base 1, a rotary control box 3 is fixedly connected to the top of the support frame plate 2, a transmission worm gear 8 is rotatably connected between the upper and lower inner walls of the rotary control box 3, a transmission worm 9 is rotatably connected between the two inner walls of the rotary control box 3, a rotating shaft 7 is rotatably connected to the top of the rotary control box 3, the rotating shaft 7 is fixedly connected to the transmission worm gear 8, and an installation ring plate 5 is fixedly connected to the top of the rotating shaft 7.

[0031] Multiple storage mechanisms 6 are fixedly installed on the mounting ring plate 5. Each storage mechanism 6 includes a storage bin 601, a switch control box 602, a transmission threaded rod 603, a transmission plate 604, an L-shaped connecting rod 605, and a conical sealing block 606. The storage bin 601 is fixedly connected to the mounting ring plate 5. The switch control box 602 is fixedly connected to the outer surface of the storage bin 601. The transmission threaded rod 603 is rotatably connected between the upper and lower inner walls of the switch control box 602. The transmission plate 604 is threadedly connected to the transmission threaded rod 603. The L-shaped connecting rod 605 is fixedly connected to the bottom of the transmission plate 604. The conical sealing block 606 is fixedly connected to one end of the L-shaped connecting rod 605 and is inserted into the bottom opening of the storage bin 601.

[0032] The injection molding equipment is fixedly installed on the top of the support base 1.

[0033] In a specific embodiment of this utility model, the injection molding equipment installed on the top of the support base 1 is a common toy injection molding equipment on the market. Multiple storage tanks 601 are used to store powdered plastics of various colors. The plastic from the storage tanks 601 is poured into the feed hopper of the injection molding equipment, then heated and melted. The molten plastic is pushed by the high pressure of the screw inside the screw barrel and rapidly injected into the closed cavity through the nozzle at the front end of the barrel. The melt filling the cavity, under pressure, cools and solidifies, maintaining the toy shape assigned by the cavity. This utility model emphasizes the automated switching and feeding of multiple colored plastic raw materials. It does not elaborate on the injection molding equipment, which is a mature technology. The model and specifications of the injection molding equipment are selected according to the actual situation. During the injection molding process, the transmission worm gear 9 is controlled to rotate, driving the transmission worm wheel 8 to rotate. The rotating shaft 7 drives the mounting ring plate 5 to rotate at a certain angle, moving the corresponding storage bin 601 to the upper side of the feed hopper of the injection molding equipment. Then, by controlling the rotation of the transmission threaded rod 603, the transmission plate 604 is driven to descend. Through the L-shaped connecting rod 605, the conical sealing block 606 is driven to descend, opening the bottom opening of the storage bin 601. After the material is discharged, by controlling the reverse rotation of the transmission threaded rod 603, the transmission plate 604 is driven to rise, so that the L-shaped connecting rod 605 drives the conical sealing block 606 to seal the bottom opening of the storage bin 601. Then, the above steps are repeated to realize the automated switching and feeding of plastic raw materials of various colors. Different colored plastic raw materials are quickly and accurately fed into the hopper, avoiding the time and labor costs of manual material changing, reducing manual intervention, reducing the risk of operational errors, and greatly improving production efficiency.

[0034] Specifically, a servo motor 4 is fixedly connected to one outer surface of the rotary control box 3, and the output end of the servo motor 4 is fixedly connected to the transmission worm gear 9.

[0035] In this embodiment, the servo motor 4 is started to drive the transmission worm gear 9 to rotate.

[0036] Specifically, the pivot rod 7 is made of stainless steel.

[0037] In this embodiment, the rotating shaft 7 is exposed to the outside for a long time, and the use of stainless steel can prevent rust.

[0038] Specifically, the storage mechanism 6 also includes a drive motor 607, which is fixedly installed on the top of the switch control box 602, and the output end of the drive motor 607 is fixedly connected to the transmission threaded rod 603.

[0039] In this embodiment, the drive motor 607 is started by controlling the drive motor 607 to drive the transmission threaded rod 603 to rotate.

[0040] Specifically, the storage mechanism 6 also includes a limiting rod 608, which is fixedly connected between the upper and lower inner walls of the switch control box 602, and the transmission plate 604 is slidably sleeved on the limiting rod 608.

[0041] In this embodiment, the limiting rod 608 keeps the transmission plate 604 stable during the lifting and lowering process.

[0042] Specifically, the L-shaped connecting rod 605 is made of stainless steel.

[0043] In this embodiment, the L-shaped connecting rod 605 is made of stainless steel, which is rust-resistant, has a smooth surface, low friction, and a long service life.

[0044] Working principle: During injection molding, the servo motor 4 is started, driving the transmission worm gear 9 to rotate, which in turn drives the transmission worm wheel 8 to rotate. This, in turn, causes the mounting ring plate 5 to rotate at a certain angle via the rotating shaft 7, moving the corresponding storage bin 601 to the upper side of the injection molding equipment's feed hopper. Then, the corresponding drive motor 607 is started, driving the transmission threaded rod 603 to rotate, causing the transmission plate 604 to descend. This, in turn, causes the conical sealing block 606 to descend via the L-shaped connecting rod 605, opening the bottom opening of the storage bin 601. After material discharge, the transmission threaded rod 603 is reversed, causing the transmission plate 604 to rise, thus causing the L-shaped connecting rod 605 to... The moving conical sealing block 606 seals the bottom opening of the storage bucket 601. By repeating the above steps, the automatic switching and feeding of plastic raw materials of various colors can be realized. Different colored plastic raw materials are quickly and accurately fed into the hopper, avoiding the time and labor costs of manual material changing, reducing manual intervention, lowering the risk of operational errors, and greatly improving production efficiency. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power component and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
