Description

Technical Field

[0001] This utility model relates to the field of friction welding mold technology, specifically to an infrared preheating vibration friction welding mold. Background Technology

[0002] Vibration friction welding is a welding method that uses an electromagnetic transmission device to generate relative motion between two thermoplastic parts, thereby generating frictional heat to form a joint. Vibration friction welding is relatively fast and can be used to weld various thermoplastics, especially widely used in the automotive and household appliance industries. For example, patent CN107962309B discloses a vibration friction welding machine, including a frame, a pressure regulating unit mounted on the frame, a lower platform connected to the pressure regulating unit that can be raised and lowered, a vibration unit mounted on the frame, and a mold device for clamping the two workpieces to be welded and vibrating them under the action of the vibration unit. However, because it lacks a preheating device, during use, when welding ordinary plastics, the temperature of the workpiece tends to rise rapidly after the machine vibrates for a period of time, resulting in uneven heat distribution. When welding high-strength plastics, there are problems such as welding difficulties and uneven weld strength, and uneven heat distribution at the plastic weld joint is prone to occur during the heat generation process of vibration friction.

[0003] Therefore, this utility model provides an infrared preheating vibration friction welding mold. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: an infrared preheating vibration friction welding mold, including a base 1 and a top plate 2. A support structure is installed between the base 1 and the top plate 2. The support structure includes multiple first support rods 7 and multiple second support rods 8. The first support rods 7 and the second support rods 8 are slidably connected. A lower mold 3 is installed on the base 1. A support seat 4 is installed on the lower side of the top plate 2. An upper mold is installed on the support seat 4. The upper mold corresponds to the lower mold 3. A positioning and adjustment structure is installed on the base 1. The positioning and adjustment structure corresponds to the lower mold 3. An infrared preheating structure is installed on the support seat 4.

[0022] Specifically, the top plate 2 can be slid upwards, allowing the slide rod 11 to slide within the second support rod 8. After sliding to a certain height, the nut 9 can be rotated to limit the second support rod 8, thus achieving a good limiting effect. Furthermore, the buffer can provide cushioning.

[0023] The infrared preheating structure includes an infrared heating tube 5, which is fixedly connected to the support base 4. The closest distance between the infrared heating tube 5 and the upper and lower molds 3 is 3.5 to 8 mm.

[0024] Specifically, before mold closing, the infrared heating tube 5 can be used for preheating, and after the lower mold 3 moves downward, demolding can be performed, thus keeping it away from the infrared heating tube 5 and preventing burns during unloading.

[0025] The positioning and adjustment structure includes multiple cylinders 12, which together form a six-degree-of-freedom vibrator. The output end of the cylinder 12 is rotatably connected to the lower mold 3, and a pneumatic chuck 6 is installed on one side of the lower mold 3.

[0026] Specifically, the extension of multiple cylinders 12 at different lengths can drive the lower mold 3 to move, thereby facilitating the adjustment of the position of the lower mold 3, ensuring accurate positioning, and the product can be fixed by the pneumatic chuck 6 to prevent displacement between the product and the lower mold 3 during the welding process.
