Description

Technical Field

[0001] This utility model relates to the field of security technology, specifically to a shield mold. Background Technology

[0002] Shields, as an important protective equipment, have wide applications in military, police, and sports fields. Traditional shield production mainly relies on manual or semi-automated equipment, resulting in low production efficiency, high costs, and inconsistent quality. To improve shield production efficiency, reduce production costs, and enhance product quality, it is necessary to research a new type of shield mold.

[0003] Existing shield molds have a relatively simple structure, typically consisting of an upper mold and a lower mold. During production, after the upper and lower molds are closed, the shield material is formed under high temperature and pressure. However, this type of mold has the following problems:

[0004] The enclosed space at the bottom of the mold results in poor cooling. Under high temperature and pressure, heat easily accumulates at the bottom of the mold, leading to uneven cooling of the shield material during molding and affecting product quality.

[0005] Poor mold venting. During the shield material molding process, air inside the mold cannot be effectively expelled, resulting in defects such as bubbles and dents on the shield surface. Utility Model Content

[0006] To address the aforementioned problems, this utility model discloses a shield mold.

[0007] To achieve the above objectives, this application discloses a shield mold, including an upper mold and a lower mold, wherein the bottom of the lower mold is suspended and the bottom space is divided to form multiple independent air ducts.

[0008] The top of the lower mold is provided with a plurality of first electromagnets along its circumference for adsorption and engagement with the upper mold.

[0009] The openings at both ends of the air duct are larger than the size of the middle section, forming a tapering or bottleneck structure.

[0010] The top of the lower mold is provided with a buffer mechanism, which has an elastic support part that can extend or retract into the corresponding opening on the lower mold.

[0011] A corresponding second electromagnet is provided inside the opening corresponding to the elastic support portion, and the second electromagnet can be attracted and engaged with the elastic support portion.

[0012] In this embodiment of the application, the bottom of the lower mold is suspended, and the top of the air duct is connected to the top surface of the lower mold through an exhaust hole to allow air circulation and material discharge. The space at the bottom of the lower mold is divided into multiple independent air ducts to ensure that air can be discharged through multiple channels during the molding process, thereby reducing air trapping inside the material and improving molding quality. Each air duct works independently, and even if one air duct is partially blocked, the other air ducts can still work normally, improving the reliability of the mold. Attached Figure Description

[0013] Figure 1 This is a perspective view of the shield mold in the embodiments of this application;

[0014] Figure 2 This is a schematic diagram of the buffer mechanism in the embodiments of this application;

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0017] Example 1: As Figure 1-3 As shown, a shield mold includes an upper mold 100 and a lower mold 200. The bottom of the lower mold 200 is suspended, and the bottom space is divided to form multiple independent air ducts 300. The top of the air ducts is connected to the top surface of the lower mold 200 through exhaust holes.

[0018] The upper mold 100 is used to form the upper part of the shield and has protrusions or forming surfaces corresponding to the shape of the upper surface of the shield;

[0019] The lower mold 200 is used to form the lower half of the shield. Its bottom is suspended in the air, and the top of the air duct is connected to the top surface of the lower mold 200 through exhaust holes (multiple exhaust holes are provided, and their diameter is small, within 0.05-0.1mm) to allow air circulation and material discharge.

[0020] The bottom space of the lower mold 200 is divided into multiple independent air ducts to ensure that air can be discharged through multiple channels during the molding process, thereby reducing air trapping inside the material and improving molding quality. Each air duct works independently, and even if one air duct is partially blocked, the others can still work normally, improving the reliability of the mold.

[0021] The openings at both ends of the air duct 300 are larger than the openings in the middle section, forming a tapering or bottleneck shape. This structure can be formed at both ends of the air duct.

[0022] The openings at both ends of the air duct 300 are larger than the size of the middle section, forming a tapering or bottleneck structure. Because the openings at both ends of the air duct are larger and the middle section is narrower, according to fluid dynamics principles, the air velocity increases when passing through the narrow section, which helps to more effectively expel air from the material.

[0023] Example 2: Figure 1 As shown, the top of the lower mold 200 is provided with a plurality of first electromagnets 400 along its circumference for adsorption and engagement with the upper mold 100.

[0024] Multiple first electromagnets 400 are arranged circumferentially on the top of the lower mold 200. These electromagnets 400 are used to engage with corresponding parts of the upper mold 100. The position and number of the electromagnets 400 are matched to the specific size and shape of the shield mold to ensure precise alignment of the upper mold 100 and the lower mold 200 and maintain a stable attraction force. The attraction force provided by the first electromagnets 400 helps maintain the stability of the mold during the molding process, especially when using high-pressure or high-speed molding processes. This prevents the mold from separating due to pressure or impact, ensuring molding quality.

[0025] At the same time, the electromagnet's attraction allows for rapid mold opening and closing, reducing the time and labor intensity required by traditional mechanical fixing methods, thereby improving production efficiency.

[0026] Example 3: As Figure 1 and 3 As shown, a buffer mechanism 600 is provided at the top of the lower mold 200. The buffer mechanism 600 has an elastic support part 700, which can extend or retract into the corresponding opening 800 on the lower mold 200.

[0027] The buffer mechanism 600 is used to provide cushioning when the mold closes, reducing the impact on the molding material.

[0028] A corresponding second electromagnet 900 is provided inside the opening 800 corresponding to the elastic support part 700, and the second electromagnet 900 can be attracted and engaged with the elastic support part 700.

[0029] The attraction between the second electromagnet 900 and the elastic support 700 can control the support. For example, by increasing the attraction force of the second electromagnet 900, the support force of the elastic support 700 is reduced when the upper mold 100 is pressed down, making it close more smoothly with the lower mold 200. When the mold is opened, the second electromagnet 900 is closed to increase the support force of the elastic support 700, thereby facilitating the separation of the upper mold 100 and the lower mold 200.

[0030] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
