[0004] The above-mentioned prior art solutions have the following defects: the driven cooling mechanism inside the cooling tube may accumulate impurities or become clogged after long-term use, resulting in reduced cooling effect. In addition, the cleaning and maintenance of the heat dissipation net may also be relatively troublesome and require regular inspection and cleaning.

[0005] Therefore, we propose a curing molding device for processing children's toys to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a curing and molding device for processing children's toys, so as to solve the problems of decreased cooling effect over a long period of time and inconvenient cleaning of the heat dissipation net proposed in the above-mentioned background technology.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 4 The utility model provides a technical solution: a curing molding device for processing children's toys, including a lower mold 1, an upper mold 2 and a support plate 5. The lower mold 1 is connected to the upper mold 2 through a guide column 4. The lower mold 1 is the main component for toy molding. The lower mold 1 provides a space for injecting plastic material, and through the curing molding device arranged inside it, it ensures that the plastic can be evenly solidified. The bottom of the lower mold 1 is fixedly connected with a base 8. The upper mold is provided with an injection port 6, which cooperates with the lower mold 1 to form a complete mold space, and the plastic material is molded inside through the mold closing action. The injection port 6 on the upper mold allows the plastic material to be injected into the mold. The upper surface of the guide column 4 is fixedly connected to the bottom of the support plate 5, and the support plate 5 provides stable support to ensure that the upper mold 1 and the lower mold 2 can be accurately aligned and molded.

[0028] There are four guide posts 4, the bottom of which is fixedly connected to the four sides of the lower mold 1 to ensure the stability and accuracy of the upper mold 2 and the lower mold 1 during the mold closing and opening process. The design of the guide posts 4 can reduce the deviation or distortion of the mold during the action process, and ensure the accuracy of toy molding. The middle part of the lower surface of the support plate 5 is fixedly connected to the cylinder 7, and the output end of the cylinder 7 is fixedly connected to the lower mold 1, so that the upper mold 2 can move up and down under the drive of the cylinder 7 to achieve the action of mold closing and opening. A curing molding device is arranged inside the lower mold 1;

[0029] The curing and molding device includes an air cooling unit and a water cooling unit;

[0030] The air cooling unit includes a slide 101, a slide 2 102, a slider 1201, a cooling fan 1202, a slider 2 1203, an electric push rod 1204, a cooling mesh plate 1002 and a connecting strip 1001. The slide 101 and the slide 2 102 are respectively provided on the bottom surface and the top surface inside the lower mold 1, providing tracks for the slider to move, ensuring that the cooling fan can move smoothly. The slider 1201 and the slider 2 1203 are respectively slidably connected inside the slide 101 and the slide 2 102. The output end of the electric push rod 1204 is fixedly connected to the left side of the slider 1201, driving the slider 1201 to move, thereby driving the cooling fan 1202 to move, and realizing heat dissipation of different areas of the mold. The upper and lower ends of the cooling fan 1202 are respectively fixedly connected to the side of the slider 1 1201 and the slider 2 1203 that are close to each other, carrying the cooling fan 1202 and allowing it to slide in the slide slot to adjust the position of the cooling fan 1202. The cooling fan 1202 generates wind flow to blow on the mold surface, take away heat, and accelerate the curing process of the plastic. The cooling mesh 1002 is flexibly connected to the front of the lower mold 1 through the connecting strip 1001, allowing air circulation, while preventing foreign matter from entering the mold, protecting the mold and the toy being cured. There are four connecting strips 1001, which are flexibly connected to the four corners of the cooling mesh 1002, connecting the cooling mesh 1002 and the mold, and facilitating the installation and removal of the cooling mesh 1002. There are two groups of air cooling units, which are respectively arranged on the front and rear sides of the outer surface of the lower mold 1. The setting of the two groups of air cooling units can increase the cooling area, so that the cooling wind can cover the mold surface more comprehensively. The front and rear sides work at the same time, which can ensure that the cooling effect of each part of the mold is more uniform, further improve the cooling efficiency, and thus accelerate the curing speed of the plastic toy;

[0031] The water cooling unit includes a placement box 11, a water tank 3, a water pump 301, an inlet pipe 301, an outlet pipe 303 and a one-way valve 304. The bottom of the placement box 11 is fixedly connected to the middle of the bottom surface of the lower mold 1. The placement box 11 is placed around the mold core inside the lower mold 1, and a coolant is arranged inside the placement box 11. The cooling of the mold is achieved through the circulation of the coolant. The right side of the water tank 3 is fixedly connected to the left side of the lower mold 1, and the water tank 3 stores the coolant. One end of the inlet pipe 301 and the outlet pipe 303 is fixedly connected to the right side of the water tank 3, and the other end of the inlet pipe 301 and the outlet pipe 303 is fixedly connected to the left side of the placement box 11 and extends into the box. The one-way valve 304 is arranged inside the outlet pipe 303 to prevent the coolant from flowing back and ensure the smooth cooling cycle. The water pump 301 is arranged on the front of the water tank to drive the coolant to circulate between the inlet pipe 301 and the outlet pipe 303 to ensure the cooling effect.

[0032] Working principle: Inject plastic material into the mold through the injection port 6. Start the cylinder 7 to drive the upper mold 2 down and close it with the lower mold 1. When the plastic toy is solidified inside the mold, the electric push rod 1204 starts to push the slider 1201 to slide in the slide groove 101, thereby driving the cooling fan 1202 to move to a suitable position. After the cooling fan 1202 is started, it generates wind flow, blows on the surface of the mold, takes away the heat on its surface, and accelerates the curing process. The heat dissipation mesh plate 1002 allows wind flow to pass through, while preventing foreign matter from entering the mold, protecting the mold and the toy.

[0033] At the same time, the water pump 301 is started to extract the coolant from the water tank 3 and transport the coolant to the placement box 11 through the water inlet pipe 301. The coolant circulates in the placement box 11, surrounds the mold core, and evenly cools the mold and the plastic toy inside. The cooled coolant returns to the water tank 3 through the outlet pipe 303, and the one-way valve 304 ensures that the coolant does not flow back.

[0034] Finally, the cylinder 7 is started to drive the upper mold 2 to rise and separate from the lower mold 1. The mold is opened and the solidified plastic toy is taken out.
