[0039] The workbench 1 is the basic support structure of the whole device, and the upper part thereof is provided with the reciprocating injection mechanism 2, which is the core working area of toy injection molding manufacturing. The raw material pretreatment mechanism 3 is installed on the upper part of the reciprocating injection mechanism 2, which is responsible for hot air drying treatment of injection molding raw materials, and delivers the treated raw materials to the reciprocating injection mechanism 2. The conveyor 4 is arranged on one side of the workbench 1 and connected with the raw material barrel 301 in the raw material pretreatment mechanism 3, which is responsible for continuously delivering external injection molding raw materials to the raw material pretreatment mechanism 3. The mold cooling mechanism 5 is installed on the lower part of one side of the workbench 1, which is specially used for cooling the mold structure in the reciprocating injection mechanism 2 to ensure the injection molding effect and efficiency. The conveyor 6 is also fixedly installed on the bottom side of the workbench 1, and the moving table of the conveyor 6 is fixedly installed with a tray. The material receiving basket 7 arranged on the upper part of the tray is used to receive the molded toy products.

[0040] The reciprocating injection mechanism 2 is specially designed, which comprises a middle seat 201 fixedly installed on one side of the top of the workbench 1 and a limiting plate 202 in the middle of the workbench 1, and further comprises three mold seats 203 fixedly installed in a V shape on the top of the workbench 1. One of the mold seats 203 is fixed in the middle of the workbench 1, and a fixed mold 204 is fixedly installed on one side of the mold seat 203. The other two mold seats 203 are also synchronously provided with a fixed mold 204 on one side, and the installation direction of the fixed mold 204 is opposite to that of the fixed mold 204 on one side of the middle mold seat 203, thereby forming multiple injection workstations.

[0041] The middle and both sides of the limiting plate 202 are slidably connected with a movable mold 205 through a plurality of slide rods. The convex mold surface of the movable mold 205 is oppositely arranged with the concave surface of the fixed mold 204 at the corresponding position on the same side. The molding cavity of the toy is realized by the closing of the movable mold and the fixed mold. A pusher 206 is fixedly installed on one side of the middle seat 201. The front end of the telescopic rod of the pusher 206 penetrates the middle seat 201 and the limiting plate 202 in sequence and is fixedly connected with one side of the middle movable mold 205, thereby providing power for the movement of the movable mold 205. The middle of the rod body of the pusher 206 is fixedly installed with a corner plate 207, and the both sides of the corner plate 207 penetrate the middle of the limiting plate 202. The both sides of the middle movable mold 205 and the both sides of the movable mold 205 are connected through a long rod respectively. When the telescopic rod of the pusher 206 moves, the middle movable mold 205 and the both sides of the movable mold 205 can realize synchronous movement under the linkage action of the corner plate 207 and the long rod, thereby ensuring the accuracy of the closing and opening actions.

[0042] A spiral injector 208 is fixedly installed on one side of each mold seat 203. The injection port of the spiral injector 208 penetrates the mold seat 203 and is communicated with the fixed mold 204, thereby being used for injecting raw materials into the mold cavity.

A moving module 8 is fixedly installed on one side of the top of the workbench 1. A connecting rod 211 is fixedly installed on the moving seat of the moving module 8. The connecting rod 211 is fixedly composed of two L-shaped limiting long rods and a U-shaped connecting plate. An electric motor 209 is fixedly installed on the middle of the moving seat of the moving module 8 at both sides of the U-shaped connecting plate. The output end of the electric motor 209 is fixedly connected with one end of the spiral rod 210 in the spiral injector 208. The spiral rod is driven to rotate by the electric motor, thereby realizing the rotary injection and linear pushing of the raw materials. The moving module 8 can drive the connecting rod 211 and the electric motor 209 to adjust the position, thereby adapting to the reciprocating injection requirement.

[0043] The raw material pretreatment mechanism 3 includes a raw material barrel 301 for storing the injection molding raw material to be processed, and a fan 305. The top of the raw material barrel 301 is fixedly installed with a driving motor 302, and the output end of the driving motor 302 penetrates through the top of the raw material barrel 301 and is fixedly installed with an agitating rod 303. Under the driving of the driving motor 302, the agitating rod 303 agitates the raw material in the raw material barrel 301. The lower part of the raw material barrel 301 is provided with a wind collecting box 304, and a wind permeable net is arranged between the raw material barrel 301 and the wind collecting box 304. The wind provided by the fan 305 enters the raw material barrel 301 through the wind collecting box 304 and the wind permeable net, and then the heat generated by the hot water in the top-mounted water tank 501 is blown out by the circulating water cooling row to dry the raw material by hot air. The lower part of the raw material barrel 301 is also installed with a plurality of conveying pipes 306, and an electromagnetic valve is installed at the communication part of each conveying pipe 306 and the raw material barrel 301. The conveying of the raw material is controlled by the opening and closing of the electromagnetic valve. The lower part of each conveying pipe 306 is installed with a heater 307 for heating and melting the raw material in the conveying pipe 306 to prepare for subsequent injection molding.

[0044] The mold cooling mechanism 5 includes a top-mounted water tank 501 fixedly installed on the upper part of the middle seat 201, and a cooling water tank 502 fixedly installed on one side of the lower part of the workbench 1. The cooling water tank 502 is communicated with a middle-mounted water tank 503 fixedly installed on one side of the workbench 1 through a water supply pipe 505. The middle-mounted water tank 503 is communicated with the top-mounted water tank 501 through a plurality of water supply pipes 504 penetrating through the two side molds 204. The top-mounted water tank 501 is communicated with a side-mounted water tank 507 installed in the middle of the workbench 1 through a plurality of water supply pipes 504. The side-mounted water tank 507 is communicated with the middle-mounted water tank 503 through a water distribution pipe 508, forming a complete cooling water circulation path. One side of the top-mounted water tank 501 is also installed with a circulating water cooling row which is communicated with the inside of the top-mounted water tank 501 to preliminarily cool the water in the water tank. The air outlet of the circulating water cooling row is communicated with the bottom of the wind collecting box 304 to realize the secondary utilization of heat. The top-mounted water tank 501 is communicated with the water inlet of the cooling water tank 502 through a backflow pipe 506, so that the water can be cooled again and recycled, improving the cooling efficiency and saving water resources.

[0045] Working principle: The injection molding production device for children's toys realizes the complete injection molding production process from raw material input to finished product output through the orderly linkage of each mechanism. The actual working principle is carried out around the four core links of raw material processing, injection molding, mold cooling and finished product conveying.

[0046] In the raw material conveying and pretreatment link, the conveyor 4 continuously conveys the external injection molding raw material into the raw material barrel 301 of the raw material pretreatment mechanism 3. After the raw material enters the raw material barrel 301, the driving motor 302 is started to drive the stirring rod 303 to rotate in the raw material barrel 301, uniformly stirring the raw material. At the same time, the fan 305 operates to generate airflow. The airflow is collected by the air collecting box 304, enters the inside of the raw material barrel 301 through the air permeable net between the raw material barrel 301 and the air collecting box 304, and performs hot air drying treatment on the raw material to remove the moisture in the raw material, so as to ensure that the raw material meets the injection molding requirements. When the raw material pretreatment is completed, the electromagnetic valve at the lower conveying pipe 306 of the raw material barrel 301 is opened, and the raw material enters the conveying pipe 306 under the action of gravity. During the conveying process, the heater 307 at the lower part of the conveying pipe 306 is started to heat and melt the raw material, so that the raw material changes into a fluid state that can be injection molded, and prepares for the subsequent injection molding.

[0047] The injection molding link is the core of the device work. The pretreated molten raw material is conveyed by the conveying pipe 306 to the spiral injector 208 of the reciprocating injection mechanism 2. At this time, the moving module 8 adjusts the position according to the injection molding requirements, drives the connecting rod 211 and the motor 209 fixed thereon to move, the output end of the motor 209 is connected with the spiral rod 210 inside the spiral injector 208, the motor 209 is started to drive the spiral rod 210 to rotate in the spiral injector 208, the spiral rod 210 rotates to push the molten raw material to the injection port, and the molten raw material is injected into the cavity formed by the closed mold of the fixed mold 204 and the movable mold 205 through the injection port penetrating the mold seat 203.

[0048] During the injection molding process, the mold closing and opening actions of the reciprocating injection mechanism 2 are performed cooperatively. The extensible rod of the pusher 206 serves as a power source, and the extension and retraction of the extensible rod drives the middle movable mold 205 to move. Since the angle plate 207 in the middle of the rod body of the pusher 206 is connected with the two side movable molds 205 through the long rod, and the movable mold 205 is connected with the limiting plate 202 through the slide rod, when the extensible rod of the pusher 206 is extended, the middle movable mold 205 moves to the same side of the fixed mold 204, and at the same time, the angle plate 207 pulls the two side movable molds 205 to move to the fixed mold 204 through the long rod, so as to realize the mold closing and opening of the middle, two side fixed molds 204 and movable molds 205, and the alternating action forms a closed cavity for raw material molding on one side, and realizes the discharging of the finished product on the other two sides through the built-in ejector pin and mold opening action. When the injection molding is completed, the extensible rod of the pusher 206 is retracted to drive the middle movable mold 205 to move reversely, and the angle plate 207 pushes the two side movable molds 205 to move reversely through the long rod, so as to realize the alternating action of mold opening and closing. The V-shaped arrangement of the three mold seats 203 and the corresponding fixed molds 204 and movable molds 205 structures enables the device to simultaneously perform multiple injection molding operations, thereby improving the production efficiency.

[0049] The mold cooling link runs through the whole process of injection molding. In the application, the mold cooling mechanism 5 provides cooling water for the whole cooling system. The cooling water enters the middle water tank 503 through the water pipe 505. The cooling water in the middle water tank 503 is delivered to the top water tank 501 through the water pipe 504 penetrating the fixed mold 204, and the fixed mold 204 is directly cooled. In the application, the cooling mode of all fixed molds 204 is consistent. The water in the middle water tank 503 and the side water tank 507 can be pumped into the inside of the top water tank 501 through the water pump installed in the inside of the top water tank 501. The cooling water in the side water tank 507 is delivered by the middle water tank 503 to form local water delivery. In the application, the water is delivered from the bottom to the top. In actual work, the circulating water cooling row on one side of the top water tank 501 can cool the cooling water in the top water tank 501. The cooled water is returned to the cooling water tank 502 through the return pipe 506 to realize the circulation of the whole cooling water system. It should be noted that the hot air generated by the circulating water cooling row is delivered to the air gathering box 304 through the air outlet, and the air current generated by the fan 305 is combined to dry the raw materials, realizing the secondary utilization of heat, improving the energy utilization rate, and avoiding the problem that when the molten raw materials are heated to high temperature in the spiral injector 208, the water evaporates to form water vapor in the form of bubbles in the raw materials, affecting the injection molding quality.

[0050] When the toy in the mold is formed and cooled, the reciprocating injection mechanism 2 completes the mold opening action, and the formed toy is ejected from the mold cavity by the ejector pin and falls down, and is caught by the material receiving basket 7 below the mold to receive the ejected toy product. When the material receiving basket 7 is full, the conveyor 6 delivers it to the designated position so that the staff can arrange and package it in sequence, thereby completing the whole injection molding process of the children's toy.

[0051] Although the embodiments of the application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the application, and the scope of the application is defined by the appended claims and their equivalents.
