Description

Technical Field

[0001] The present disclosure relates to a molding device, particularly a plastic sintering molding device. Background Art

[0002] The PE sintered filter material is a porous filter material made from polyethylene (PE) as raw material through sintering, which has excellent chemical stability and corrosion resistance and is currently widely used in fields such as air filtration, liquid filtration, and water treatment in industrial manufacturing.

[0003] The traditional manufacturing process of PE sintered filter materials usually includes steps such as raw material preparation, mixing and pressing, sintering, and cooling and molding. First, the mixed PE powder is loaded into a mold for pressing to form a blank with the required shape. Then, the mold is sent into an oven for sintering and shaping. During the sintering process, the temperature in the oven drops rapidly after baking is completed. When the next mold is placed in the oven, it needs to be reheated, resulting in an extended sintering operation time and affecting production efficiency.

[0004] In addition, the heat source of the traditional oven does not directly heat the blank but indirectly heats it, which causes uneven heating of the blank, resulting in inconsistent hole sizes after the filter material is formed, and further affecting the strength of the overall structure and the filtering effect. These problems limit the use of PE sintered filter materials in applications with higher requirements and need to be improved to enhance product quality and production efficiency. Summary of the Utility Model

[0005] To solve the above problems, the present disclosure provides a plastic sintering molding device, in which a heating element that directly contacts and heats the molding mold is provided in the heating device, so that the filter material blank in the molding mold is evenly heated, ensuring production quality and production efficiency.

[0006] In an embodiment of the present disclosure, a plastic sintering molding device is provided, which includes a heating device, a heating element, a constant temperature controller, and a molding mold. The heating device has a heating chamber; the heating element is arranged in the heating chamber; the constant temperature controller is arranged on the heating device and electrically connected to the heating element; the molding mold can be placed in the heating chamber, and the heating element directly contacts the molding mold for heating.

[0007] In another embodiment of the present disclosure, the heating element has a first heating part and a second heating part, and the first heating part and the second heating part are symmetrically arranged on both sides of the heating chamber respectively.

[0008] In another embodiment of the present disclosure, the heating device is pivotally provided with a door body that can close the heating chamber.

[0009] In another embodiment of the present disclosure, the molding mold includes an upper mold and a lower mold.

[0010] In this way, the present disclosure directly contacts the heating element with the forming die, so that the filter material blank is uniformly heated, ensuring that the hole sizes after forming are consistent, and improving the filtering effect and structural strength of the filter material.

[0014] To facilitate the description of the central idea expressed in the above-mentioned "Summary of the Invention" section of the present disclosure, specific embodiments are used for illustration. The various different objects in the embodiments are drawn according to the ratio suitable for listing description, rather than the ratio of the actual components. This is hereby stated in advance.

[0015] Please refer to Figures 1 to 3 As shown, the present disclosure provides a plastic sintering forming equipment 100, which includes a heating device 10, a heating element 20, a constant temperature controller 30, and a forming die 40.

[0016] The heating device 10 is a box-shaped structure. The heating device 10 has a heating chamber 11 for placing the forming die 40. The heating device 10 is pivotally provided with a door 12, and the door 12 can selectively close the heating chamber 11.

[0017] The heating element 20 is arranged in the heating chamber 11. In the embodiment of the present disclosure, the heating element 20 has a first heating part 21 and a second heating part 22, and the first heating part 21 and the second heating part 22 are symmetrically arranged on both sides of the heating chamber 11 respectively, for example, the upper side and the lower side. In other embodiments, it can also be the left and right sides. In other embodiments, the heating element 20 can also be evenly distributed on the inner wall of the heating chamber 11.

[0018] The constant temperature controller 30 is arranged on the heating device 10 and is electrically connected to the heating element 20. The constant temperature controller 30 can control the operation of the heating element 20 and control the heating element 20 to maintain a certain temperature.

[0019] The forming die 40 is made of a highly heat-conductive material, such as aluminum or copper. The forming die 40 can be placed in the heating chamber 11, allowing the heating element 20 to directly contact the forming die 40 for heating. In the embodiment of the present disclosure, the forming die 40 includes an upper die 41 and a lower die 42. A pressed filter media blank 1 is placed between the upper die 41 and the lower die 42. When the forming die 40 is placed in the heating chamber 11, the upper die 41 contacts the first heating part 21, and the lower die 42 contacts the second heating part 22, so that the filter media blank 1 is directly heated and formed, achieving a uniform heating effect to ensure that the pore sizes of the formed filter media are consistent and have better structural strength.

[0020] Since the heating device 10 controls the heating element 20 to maintain a constant temperature through the thermostat 30, when the forming die 40 originally in the heating chamber 11 is taken out after heating, the temperature in the heating chamber 11 still remains at a certain temperature. In this way, when the next forming die 40 is placed in the heating chamber 11, there will be no problem of a rapid temperature drop in the heating chamber 11. Thus, for the heating time of the forming die 40, the production efficiency is maintained at a high level.

[0021] In summary, the present disclosure has the following advantages:

[0022] 1. Uniform heating: The heating element 20 directly contacts the forming die 40 for heating, making the filter media blank 1 heated uniformly, ensuring that the pore sizes after forming are consistent, and improving the filtering effect and structural strength of the filter media.

[0023] 2. Stable temperature: The thermostat 30 controls the heating element 20 to maintain a certain temperature, avoiding temperature fluctuations during the heating process and ensuring the stability of the heating process; and maintaining a constant temperature state when replacing the forming die 40, reducing the problem of a rapid temperature drop in the heating chamber 11, effectively controlling the heating time, and improving the production efficiency.

[0024] The above-described embodiments are merely illustrative of the present disclosure and are not intended to limit the scope of the present disclosure. All modifications or variations made without departing from the spirit of the present disclosure fall within the scope intended to be protected by the present disclosure.
