Description

Technical Field

[0001] This utility model relates to the field of conductive foam processing technology, and in particular to a conductive foam hot melt cooling molding device. Background Technology

[0002] Conductive foam, as a material that combines conductivity and cushioning / shock absorption, is widely used in fields such as electromagnetic shielding and signal interference protection for electronic equipment.

[0003] Traditional conductive foam hot melt cooling molding devices still have the following problems: 1. The heating structure of traditional conductive foam hot melt cooling molding devices uses a single heating tube, which results in uneven heating and low efficiency, causing the conductive foam to not be fully melted and affecting the subsequent molding effect; 2. Traditional conductive foam hot melt cooling molding devices lack a cooling circulation structure, and the cooling water is directly discharged after use, which increases production costs. Therefore, we have launched a conductive foam hot melt cooling molding device. Utility Model Content

[0004] The main objective of this invention is to provide a conductive foam hot melt cooling molding device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A conductive foam hot-melt cooling molding device includes a hot-melt box and a cooling box. A heating structure is inserted and fixedly connected inside the hot-melt box. A sealing component is movably sleeved on the upper end of the hot-melt box. A first box cover is movably sleeved on the upper end of the cooling box. A first handle is fixedly connected to the middle of the upper end of the first box cover. A cooling water circulation pipe inlet pipe is inserted and fixedly connected to the upper part of the outer surface of the cooling box. A cooling water circulation pipe outlet pipe is inserted and fixedly connected to the lower part of the outer surface of the cooling box.

[0007] Preferably, the heating structure includes an inner box and a heater. The outer surface of the inner box is spirally surrounded by a spiral heating wire. The upper end of the spiral heating wire away from the inner box is electrically connected to a power line. The end of the power line away from the spiral heating wire is electrically connected to the heater. The heater is disposed on the outer surface of the hot melt box.

[0008] By adopting the above technical solution, the spiral heating wire surrounds the inner box for heating, increasing the heating area and making the conductive foam heat more evenly. Combined with the heater, the heat melting efficiency is effectively improved.

[0009] Preferably, the inner box is fixedly fitted inside the hot melt box, and the spiral heating wire is disposed between the inner box and the hot melt box. The upper end of the spiral heating wire, away from the inner box, penetrates the inner wall of the hot melt box and extends to the outside of the hot melt box.

[0010] By adopting the above technical solution, it is easy to connect the spiral heating wire to the external heater.

[0011] Preferably, the sealing assembly includes a second lid, a sealing ring is fixedly connected to the lower edge of the second lid, a second handle is fixedly connected to the upper left and upper right of the second lid, and an extruded structure is inserted into the upper middle of the second lid.

[0012] By adopting the above technical solution, the second box cover and the sealing ring are matched to ensure the internal sealing of the hot melt box and prevent heat loss and impurities from entering during the hot melt process.

[0013] Preferably, the second box cover is located on the hot melt box, and the sealing ring is movably fitted inside the inner box and in close contact with the inner wall surface of the inner box.

[0014] By adopting the above technical solutions, the sealing effect inside the hot melt box is enhanced, ensuring a stable hot melt environment and providing a guarantee for the full hot melt of conductive foam.

[0015] Preferably, the extrusion molding structure includes a screw and an extrusion plate. A knob is fixedly connected to the upper end of the screw, and a return spring is fixedly connected to the upper end of the extrusion plate. The upper end of the return spring is fixedly connected to the lower end of the second cover, and the lower end of the screw is threadedly connected to the upper end of the second cover.

[0016] By adopting the above technical solution, the screw is rotated by rotating the knob, which moves the extrusion plate up and down, thereby extruding and molding the conductive foam after hot melting. The structure is simple and the operation is convenient.

[0017] Preferably, the upper end of the extrusion plate has a guide hole in the middle, and the lower part of the screw is movably sleeved in the guide hole.

[0018] By adopting the above technical solution, the guide hole guides the screw, ensuring the stability of the extrusion plate during its up-and-down movement and preventing deviation.

[0019] Preferably, the extrusion plate is located inside the inner box and is in close contact with the inner wall of the inner box, and the screw is located inside the return spring and has a gap with the inner wall of the return spring.

[0020] By adopting the above technical solution, the extrusion plate can fully fit the inner wall of the inner box, ensuring uniform extrusion of the conductive foam. The return spring can drive the extrusion plate to automatically return after extrusion, which facilitates the next operation and improves production continuity.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In this utility model, by setting a spiral heating wire that spirals around the outer surface of the inner box, in conjunction with a heater, uniform and efficient heating of the conductive foam material inside the inner box can be achieved. In use, the conductive foam material is placed into the inner box, the power cord is connected and the heater is turned on. The spiral heating wire can quickly and uniformly transfer heat, greatly shortening the hot-melt time and improving the hot-melt efficiency. At the same time, the cooperation between the sealing component and the extrusion molding structure allows the screw to rotate by rotating the knob after hot-melt, pushing the extrusion plate to move downward along the inner wall of the inner box, which can extrude the conductive foam in the hot-melt state to ensure the molding effect and effectively solve the problems of uneven hot-melt and poor molding effect in traditional methods.

[0023] 2. In this utility model, the cooling box is equipped with a cooling water circulation pipe inlet pipe and a cooling water outlet pipe. When in use, the inlet pipe is connected to the cooling water outlet and the outlet pipe is connected to the cooling water inlet to form a circulating cooling system. When the hot-pressed material is placed into the cooling box, the circulating cooling water can cool the conductive foam, saving production costs. Attached Figure Description
