A thermoforming composite device for security doors

Abstract

This utility model provides a hot-pressing composite device for anti-theft doors, including a main body with a main cavity inside. An inlet / outlet is located on one end of the main body. An upper mold, an electric telescopic rod, and a limiting base plate are fixedly installed inside the main cavity. A lower mold is rotatably installed inside the main cavity. The upper and lower molds interlock to form a composite cavity. The electric telescopic rod is slidably connected to the upper mold. A hot-pressing plate is fixedly connected to one end of the electric telescopic rod near the composite cavity, and the other end of the electric telescopic rod is fixedly connected to one side wall of the main cavity. The limiting base plate limits the rotation angle of the lower mold. This design uses a gradient arrangement of heating tubes with gradually decreasing spacing along the central axis of the hot-pressing plate to increase the heating density at the edge of the hot-pressing plate, compensating for heat loss and improving the temperature uniformity of the hot-pressing plate. This improves the hot-pressing effect and increases the yield rate.

Description

Technical Field

[0001] This utility model relates to the technical field of anti-theft door production and processing equipment, specifically an anti-theft door hot-pressing composite equipment. Background Technology

[0002] In the field of security door manufacturing, hot-pressing lamination is a core process to ensure a firm bond between the door panel, filling layer, and back panel. However, existing hot-pressing lamination equipment still faces two major technical bottlenecks:

[0003] Uneven temperature distribution during hot pressing:

[0004] Traditional equipment uses evenly distributed heating tubes. Because the heat dissipation rate at the edges of the hot press plate is higher than that at the center, the edge temperature is significantly lower. This problem results in insufficient adhesion strength of the composite film at the door edge, easily causing defects such as delamination and blistering, directly affecting the sealing and durability of the security door.

[0005] The material feeding and discharging process relies too heavily on manual intervention:

[0006] Current equipment mostly uses fixed molds, requiring manual positioning and loading / unloading of the door body, or relying on multiple power sources to control the opening, closing, and resetting of the mold. This type of design is not only inefficient to operate, but also has a complex mechanical structure, a high failure rate, and is difficult to meet the needs of continuous production.

[0007] Therefore, there is an urgent need for a composite equipment that can simultaneously optimize the thermal field distribution and operating process, so as to achieve efficient and automated production while ensuring bonding quality. Utility Model Content

Detailed Implementation

[0026] This utility model embodiment provides a heat-pressing composite device for anti-theft doors, such as... Figure 1-4 As shown, it includes a main body 11, a main cavity 12, an inlet / outlet 13, an upper mold 14, a lower mold 15, an electric telescopic rod 16, a hot press plate 17, a limiting base plate 18, a heating cavity 20, a heating tube 21, a fixed connecting rod 22, a driving connecting rod 23, a sliding connecting rod 24, a sliding slot 25, an elastic element 26, and a heat insulation baffle 27.

[0027] like Figure 1-4 As shown, a main cavity 12 is provided inside the main body 11, and an inlet / outlet 13 is provided on one end face of the main body 11. An upper mold 14, an electric telescopic rod 16, and a limiting base plate 18 are fixedly installed inside the main cavity 12. A lower mold 15 is rotatably installed inside the main cavity 12. The upper mold 14 and the lower mold 15 are interlocked to form a composite cavity. The electric telescopic rod 16 is existing technology. The electric telescopic rod 16 is slidably connected to the upper mold 14. A hot press plate 17 is fixedly connected to one end of the electric telescopic rod 16 near the composite cavity. The other end of the electric telescopic rod 16 is fixedly connected to one side wall of the main cavity 12. The limiting base plate 18 is used to limit the rotation angle of the lower mold 15.

[0028] A heating chamber 20 is provided inside the hot press plate 17. Several heating tubes 21 are fixedly connected inside the heating chamber 20. The spacing between the heating tubes 21 gradually decreases from the central axis of the hot press plate 17 to both sides. The gradient arrangement of the heating tubes 21 increases the temperature of the edge area of ​​the hot press plate 17 and improves the problem of uneven temperature at the edge of the hot press plate 17.

[0029] Two fixed connecting rods 22 are fixedly connected to both sides of the main cavity 12. One end of the two fixed connecting rods 22 is fixedly connected to the upper mold 14, and the other end of the two fixed connecting rods 22 is fixedly connected to one side wall of the main cavity 12.

[0030] Both sides of the main cavity 12 are rotatably connected to drive connecting rods 23, and drive motors are connected to the external drive connecting rods 23. Both sides of the main cavity 12 are provided with sliding slots 25, which are arc-shaped slots. Sliding connecting rods 24 are slidably connected in the sliding slots 25. Elastic members 26 are fixedly connected to the sliding connecting rods 24. The end of the elastic member 26 away from the sliding connecting rods 24 is fixedly connected to one end face of the sliding slots 25.

[0031] The limiting base plate 18 has an inclined surface on one side near the lower mold 15. The inclined surface of the limiting base plate 18 is adapted to the lower mold 15. The upper mold 14 has a heat insulation baffle 27 fixedly connected on one side near the inlet / outlet 13. The heat insulation baffle 27 is adapted to the lower mold 15.

[0032] When performing hot-pressing composite bonding of the security door using this method, firstly, the security door and the composite film are tightly bonded together, and the heating tube 21 is activated for preheating. The drive motor drives the drive linkage 23 to rotate, and the drive linkage 23 drives the lower mold 15 to rotate relative to the upper mold 14. The lower mold 15 rotates until it contacts the inclined surface of the limiting base plate 18. At this time, the lower mold 15 drives the sliding linkage 24 to slide along the sliding slot 25. The sliding linkage 24 compresses the elastic element 26 and pushes the security door into the lower mold 15 through the inlet / outlet port 13. The drive motor drives the drive linkage 23 to rotate, and the lower mold 15 is reset through the cooperation of the elastic element 26 and the sliding linkage 24.

[0033] Then, the electric telescopic rod 16 pushes the hot press plate 17 to move towards the lower mold 15. The hot press plate 17 hot presses the security door and laminates the composite film onto the security door. Finally, the drive motor drives the drive linkage 23 to rotate. The drive linkage 23 drives the lower mold 15 to rotate relative to the upper mold 14. The lower mold 15 rotates until it contacts the inclined surface of the limiting base plate 18. The security door slides out along the lower mold 15 through the inlet / outlet port 13. The drive motor drives the drive linkage 23 to rotate and, through the cooperation of the elastic element 26 and the sliding linkage 24, resets the lower mold 15.
