Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, and more specifically, to a hot-pressing mold for preventing aluminum foil from jumping out of place. Background Technology

[0002] Aluminum foil heaters are generally used for defrosting and are installed in refrigerators or freezers to prevent excessive ice buildup that could prevent doors from opening, drains from overflowing, or for defrosting. An aluminum foil heater consists of heating wires, aluminum foil, connecting wires, and connectors. The heating wires need to be bonded to the aluminum foil; therefore, in production, the heating wires are arranged in a mold, and the aluminum foil is placed on top. A hot press is then used to bond the heating wires and aluminum foil together. Typically, ordinary molds have grooves for the heating wires; pins around the edges are used to limit the movement of the aluminum foil; and springs at the wire outlet secure the ends of the wire.

[0003] The manufacturing process of aluminum foil heaters involves arranging heating wires in a slotted metal mold, with the mold groove depth slightly smaller than the wire diameter, and then placing an aluminum foil on top. The side of the aluminum foil that contacts the heating wire has an acrylic and PVC coating. The coating is melted and bonded to the PVC of the heating wire using a hot press.

[0004] In actual production, due to the need for tight and complex wiring in certain heating areas, workers often experience wire skipping when attempting to lay the wires quickly. This is because the mold groove depth is smaller than the heating wire diameter, and the heating wire is relatively stiff. When passing through complex areas, the heating wire is subjected to rebound force and jumps out of the groove. This requires workers to re-lay the wires, affecting efficiency and output, resulting in poor overall performance. Therefore, this invention proposes an anti-skid-wire aluminum foil heat-pressing mold. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-skid aluminum foil hot-pressing mold. This mold avoids skipping during wiring by designing movable inserts in complex winding areas.

[0006] To solve the above-mentioned technical problems, the present invention achieves its objective as follows: The present invention relates to a heat-pressing mold for anti-skid wire aluminum foil, comprising a mold body. The top of the mold body has at least one multi-bend spiral groove, the depth and width of which are equal along their extension trajectory. The top of the mold body consists of a high-density area where the groove bends are concentrated and a low-density area outside the high-density area. The mold body has a vertically penetrating mounting hole. A movable insert with its top portion extending out of the mounting hole is slidably connected within the mounting hole. A pressure block connected to the mold body is located at the bottom of the movable insert. An elastic element is provided between the pressure block and the movable insert. A first retaining ring is provided on the outer wall of the movable insert, and a second retaining ring is provided on the inner wall of the mounting hole to block the first retaining ring. The first retaining ring is tightly pressed against the second retaining ring under the elastic force of the elastic element. The groove in the high-density area is located on the top of the movable insert. In its natural state, the bottom height of the groove on the movable insert is not higher than the bottom height of the groove outside the movable insert in its natural state.

[0007] The invention is further configured such that the bottom height of the groove on the movable insert in its natural state is lower than the bottom height of the groove outside the movable insert in its natural state.

[0008] The invention is further configured such that when the top of the movable insert is pressed, the movable insert moves down until its top surface is flush with the top surface of the mold body.

[0009] The present invention is further configured such that the number of mounting holes is determined by the number of high-density areas where the bends of the wire groove are concentrated.

[0010] The present invention is further configured such that: the mold body is provided with positioning pins.

[0011] The present invention is further configured such that the elastic element is a compression spring.

[0012] In summary, the present invention has the following beneficial effects: The anti-skid wire aluminum foil hot pressing mold involved in the present invention has a movable insert designed in the complex wiring area of ​​the mold, so that the wire groove in the area is deeper than the diameter of the heating wire. A spring is set under the movable insert. During hot pressing, the spring contracts under the action of the pressure plate, so that the movable insert area is flush with other areas, thus completing the hot pressing operation. The above design achieves the purpose of anti-skid wire, with complete overall function and strong practicality. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are merely for further illustrating the features and advantages of the present invention, and not for limiting the scope of the patent claims of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See Figures 1 to 3 As shown, the anti-skid wire aluminum foil hot-pressing mold involved in this embodiment includes a mold body 1. The mold body 1 is provided with a positioning pin (not marked). The top of the mold body 1 is provided with at least one multi-bend spiral groove 2. The depth and width of the groove 2 are equal along its extension trajectory. The top of the mold body 1 is composed of a high-density area 100 where the bends of the groove 2 are concentrated and a low-density area 200 outside the high-density area. The mold body 1 is provided with a vertically penetrating mounting hole 3. A movable insert 4 with its top part extending out of the mounting hole is slidably connected in the mounting hole 3. The bottom of the movable insert 4 is provided with a pressure block 5 connected to the mold body 1. An elastic element 6 is provided between the pressure block 5 and the movable insert 4. The elastic element 6 is a compression spring. A first retaining ring 7 is provided on the outer wall of the movable insert 4. A second retaining ring 8 is provided on the inner wall of the mounting hole 3 to block the first retaining ring. The first retaining ring 7 is tightly attached to the second retaining ring 8 under the elastic force of the elastic element 6. The wire groove 2 in the high-density area 100 is opened on the top of the movable insert 4. The bottom height of the wire groove 2 on the movable insert 4 in the natural state is lower than the bottom height of the wire groove 2 outside the movable insert 4 in the natural state.

[0020] Furthermore, when the top of the movable insert 4 is pressed, the movable insert 4 moves down until its top surface is flush with the top surface of the mold body 1.

[0021] In this embodiment, a wire groove 2 is formed on the mold body 1 for most of the wiring and support. Areas with complex wiring are hollowed out, i.e., mounting holes 3 are created, into which the movable insert 4 is installed. Finally, a movable insert pressure block 5 is used to fix it to the mold body 1 at the bottom for sealing. A spring is installed between the movable insert and the pressure block. In its natural state, the wire groove of the movable insert is deeper than the surrounding ordinary wire groove, ensuring that the heating wire is completely within the groove during wiring, preventing wire skipping. Under the action of the hot press plate, the insert moves downwards until its plane is flush with the mold body plane.

[0022] The number of mounting holes 3 is determined by the number of high-density areas 100 where the bends of the wire groove 2 are concentrated. When there are multiple high-density areas 100 where the bends are concentrated, more movable inserts 4 can be arranged at each position to deal with the skipping wire phenomenon at the corresponding position.

[0023] The anti-skid-wire aluminum foil hot-pressing mold involved in this invention features a movable insert designed in areas with complex wiring patterns. This makes the wire groove in these areas deeper than the diameter of the heating wire. A spring is installed under the movable insert. During hot pressing, the spring contracts under the action of the pressure plate, making the movable insert area flush with other areas, thus completing the hot pressing operation. This design achieves the purpose of preventing skipped wires. It also helps employees avoid skipped wires during rapid operations, improving their work efficiency and showing broad application prospects.
