[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an injection molding mold for a cooker handle, including a lower mold 1 and an upper mold 2. The upper mold 2 is located above the lower mold 1 and is connected to a hydraulic device. A cooling mechanism 3 is fixedly connected to the bottom of the lower mold 1. The cooling mechanism 3 includes a base plate 31, a cooling plate 32, and an electric cylinder 33. The lower mold 1 is fixedly installed on the upper surface of the base plate 31, and the electric cylinder 33 is fixedly installed on the side of the base plate 31. One end of the piston rod of the electric cylinder 33 is engaged with the cooling plate 32. The cooling plate 32 is located on both sides of the lower mold 1. Guide grooves 7 are provided on the upper surface of the lower mold 1 and the lower surface of the upper mold 2. Sealing plates 35 are fixedly installed on both sides of the lower mold 1.

[0023] The specific settings and functions of this embodiment are described below. The upper mold 2 is connected to the hydraulic device, which enables the mold to close and open with the lower mold 1. After mold closure, the cookware handle is injection molded. After injection molding, the electric cylinder 33 located on the side of the base plate 31 drives the piston rod to move the cooling plate 32, so that the cooling plate 32 cools both sides of the lower mold 1, accelerating the molding speed. The sealing plates 35 on both sides of the upper mold 2 can block the guide groove 7 during cooling or injection molding, playing a sealing and protective role. Its beneficial effect is that the hydraulic device enables stable mold closure and opening. The guide groove 7 surrounds the mold's shaping cavity, allowing cold air to gather in the guide groove 7 and absorb the heat in the mold. The cooling plate 32 is located on the side of the mold and is in contact with the external environment, which can maintain a relatively low temperature. It can also be further reduced in temperature by contacting the refrigeration device. The electric cylinder 33 drives the cooling plate 32 to efficiently cool the mold to accelerate the molding of the handle. The sealing plate 35 provides good sealing and protection. The cooperation of each component improves the efficiency and quality of the cookware handle injection molding.

[0024] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, side plates 4 are fixedly installed on both sides of the lower mold 1. Positioning holes 5 are opened inside the side plates 4. Positioning protrusions 6 are fixedly installed at the corners of the lower mold 1. Limiting plates 36 are fixedly installed at the edges of the base plate 31. One side of the limiting plate 36 is in contact with the cooling plate 32. A strip groove 37 is opened on one side of the limiting plate 36. A roller 310 is rotatably installed at one end of the cooling plate 32. The roller 310 is located inside the strip groove 37. A docking block 38 is fixedly installed on one side of the cooling plate 32. Positioning holes 5 are opened on one side of the side plates 4. A slot 39 is opened at the junction of the cooling plate 32 and the transmission rod 34.

[0025] The overall effect of this embodiment is that positioning holes 5 are provided on the side plates 4 on both sides of the lower mold 1, which can cooperate with other components to achieve positioning. The positioning protrusions 6 at the corners of the lower mold 1 can further improve the positioning accuracy when the mold is closed. One side of the limiting plate 36 on the edge of the base plate 31 is in contact with the cooling plate 32, which limits the movement of the cooling plate 32. The roller 310 at one end of the cooling plate 32 is located inside the strip groove 37 on one side of the limiting plate 36, so that the cooling plate 32 moves more smoothly and steadily. The mating block 38 on one side of the cooling plate 32 can cooperate with the positioning holes 5 on the side plate 4 to achieve precise alignment. To ensure accurate cooling position, the groove 39 at the junction of the cooling plate 32 and the transmission rod 34 enhances the stability of their connection. Its beneficial effect is that the positioning hole 5 and positioning protrusion 6 of the side plate 4 improve the positioning accuracy of the mold. The limiting plate 36, the strip groove 37 and the roller 310 make the movement of the cooling plate 32 more stable. The mating block 38 cooperates with the positioning hole 5 to ensure accurate cooling position. The groove 39 enhances the stability of the connection between the cooling plate 32 and the transmission rod 34. The synergistic effect of each component further improves the stability and reliability of the mold operation, which is conducive to improving the injection molding quality of the cookware handle.

[0026] The usage and working principle of this device are as follows: During use, the upper mold 2 is connected to the hydraulic device, and the positioning protrusion 6 guides the positioning, achieving mold closing between the lower mold 1 and the upper mold 2. Simultaneously, the positioning protrusion 6 at the corner of the lower mold 1 and the positioning holes 5 on the side plates 4 further improve the mold closing positioning accuracy. After mold closing, the cookware handle is injection molded. During the injection molding process, the sealing plates 35 on both sides of the lower mold 1 block the guide groove 7, providing sealing and protection. After injection molding is completed, the electric cylinder 33 on the side of the base plate 31 drives the piston rod to move the cooling plate 32. During the movement, the roller 310 at one end of the cooling plate 32 rolls in the strip groove 37 of the limiting plate 36 at the edge of the base plate 31. The limiting plate 36 limits the movement of the cooling plate 32, allowing the cooling plate 32 to move smoothly. The docking block 38 on one side of the cooling plate 32 precisely docks with the positioning hole 5 of the side plate 4 to ensure accurate cooling position. The cooling plate 32 is securely connected to the transmission rod 34 through the slot 39, cooling both sides of the lower mold 1 to accelerate the molding speed. After cooling is completed, the hydraulic device drives the lower mold 1 and the upper mold 2 to open the mold, completing one injection molding of the cookware handle.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
