Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding, in particular to an ultrasonic welding mould. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. Their accessories contain a large number of plastic products and need to be welded using an ultrasonic welding machine.

[0003] Ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the two surfaces of the objects rub against each other to form a fusion between the molecular layers. When ultrasonic waves act on the contact surface of thermoplastic plastics, they will produce high-frequency vibrations of tens of thousands of times per second. This high-frequency vibration with a certain amplitude transmits ultrasonic energy to the welding area through the upper weldment. Since the welding area, i.e. the interface between the two welds, has a large acoustic resistance, local high temperature will be generated. Due to the poor thermal conductivity of plastics, it cannot be dissipated in time and gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain pressure is applied, it is fused into one.

[0004] In order to realize the positioning of the workpiece, a mold with a mold groove is required to position the workpiece, and then ultrasonic welding is performed. The welded workpiece is placed in the mold groove, and it is not convenient to take it out. Therefore, we propose an ultrasonic welding mold. Utility Model Content

[0005] The utility model aims to provide an ultrasonic welding mold, in which a liftable support plate is arranged in the mold groove of the lower mold, and connecting plates that can slide through to the outside are connected on both sides of the support plate, a horizontal iron plate is fixed on the top through a vertical plate, and a horizontal plate with a magnet is fixed on the bottom side of the welding head. After the welding head is lowered to complete the welding of the plastic part, the horizontal plate and the magnet will be raised together, and the support plate will be raised by adsorbing the iron plate by the magnet, which is convenient for supporting and taking out the plastic part, thereby solving the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultrasonic welding mold, comprising a lower mold and a welding head, the welding head is located directly above the lower mold, and a support plate that can slide up and down is supported in the mold groove of the lower mold; both ends of the support plate are connected with connecting plates that can slide through to the outside, and a vertical plate is vertically fixed on the upper outer side of the connecting plate, and an iron plate is horizontally fixed on the top of the vertical plate; horizontal plates are horizontally fixed to the lower surfaces of both sides of the welding head, and magnets are fitted and fixed on the surface of the horizontal plates.

[0007] By adopting the above technical solution, the welding head is installed under the transducer of the welding machine, and the lower mold is fixed on the surface of the workbench by using the bottom plate and the clamp. The welding machine drives the welding head to move and cooperates with the lower mold to weld the plastic parts. After the welding is completed, the welding head rises to a higher height, which drives the horizontal plate and the magnet to rise together. The iron plate can be sucked upward by the magnet, and the support plate can be driven to rise to a higher height, so that the plastic parts can be supported to be taken out of the mold groove of the lower mold.

[0008] Optionally, a mounting screw groove is provided on the top surface of the welding head, and the mounting screw groove is located in the middle position of the top of the welding head.

[0009] By adopting the above technical solution, when in use, the welding head is fixed below the transducer of the welding machine through the mounting screw groove on the top of the welding head.

[0010] Optionally, a bottom plate is fixed to the bottom surface of the lower mold, and the lower mold is located in the middle of the surface of the bottom plate.

[0011] By adopting the above technical solution, the bottom plate of the lower mold is used in conjunction with a clamp to clamp the lower mold on the workbench surface directly below the welding head.

[0012] Optionally, the surfaces on both sides of the lower mold are provided with through-holes, and the connecting plate passes through the through-holes to the outside of the lower mold.

[0013] By adopting the above technical solution, the connecting rod will be limited in its lifting height by the hole when sliding upward, so as to prevent the support plate from rising and sliding out of the mold groove.

[0014] Optionally, the transverse plate is located directly above the iron plate, and is arranged parallel to the iron plate.

[0015] By adopting the above technical solution, it is ensured that the horizontal plate and the iron plate can be aligned closely, so that the iron plate can be raised by magnet adsorption later.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. The technical solution of the present application is to provide a liftable support plate in the die groove of the lower die, with connecting plates slidably extending to the outside connected to the two sides, a horizontal iron plate fixed on the top by a vertical plate, and a horizontal plate with a magnet fixed on the bottom side of the welding head. After the welding head is lowered to complete the welding of the plastic part, the horizontal plate and the magnet will be raised together, and the support plate will be raised by the magnet adsorbing the iron plate, so as to facilitate the support and removal of the plastic part.

[0018] 2. The technical solution of the present application allows the connecting plate to slide through the through-hole. While the through-hole guides the sliding of the connecting plate, it also limits the height of the supporting plate to prevent it from being magnetically attracted to the outside of the mold groove.

[0023] See also Figure 1-2 The utility model provides a technical solution: an ultrasonic welding mold, including a lower mold 1 and a welding head 2, a bottom plate 3 is fixed to the bottom surface of the lower mold 1, the lower mold 1 is located in the middle position of the surface of the bottom plate 3, and the surface area of ​​the bottom plate 3 is larger than the bottom area of ​​the lower mold 1, the lower mold 1 can be supported and placed on the surface of a workbench through the bottom plate 3, and clamped and locked by a clamp, so that the lower mold 1 is locked on the surface of the workbench.

[0024] A support plate 11 that can slide up and down is supported in the mold groove of the lower mold 1. Through holes 12 that are connected to the mold groove are opened on the surface of the lower mold 1 on both sides of the support plate 11. A connecting plate 111 is connected and fixed to the side of the support plate 11 at the through hole 12. The connecting plate 111 can slide to the outside of the lower mold 1 through the through hole 12. A vertical plate 4 is vertically fixed above the outer side of the connecting plate 111, and an iron plate 41 is horizontally fixed on the top of the vertical plate 4.

[0025] A mounting screw groove 22 is provided on the top surface of the welding head 2, and the mounting screw groove 22 is located in the middle position of the top of the welding head 2. The welding head 2 is installed on the transducer of the welding machine through the mounting screw groove 22, and is located directly above the lower mold 1. A cross plate 21 is laterally fixed to the lower surface of both sides of the welding head 2, and a magnet 211 is fixed on the surface of the cross plate 21. When the welding head 2 is driven to lower the height to weld the plastic parts located in the mold groove of the lower mold 1, the cross plate 21 will be close to the surface of the iron plate 41. The cross plate 21 is located directly above the iron plate 41 and remains parallel to it. After welding, when the welding head 2 is driven to rise in height, the cross plate 21 drives the magnet 211 to rise in height, and uses the magnetic attraction force to drive the iron plate 41 and the connecting plate 111 to rise in height, which can drive the support plate 11 to rise in height to support the plastic parts, making it convenient to take out the welded plastic parts.

[0026] When in use, the welding head 2 is installed under the transducer of the ultrasonic welding machine using the mounting screw groove 22 on the top of the welding head 2, and the lower mold 1 is fixed to the surface of the workbench directly below the welding head 2 using a clamp in conjunction with the bottom plate 3. When welding plastic parts, the two parts are positioned in the mold groove of the lower mold 1 and supported on the surface of the support plate 11 through the mold groove of the lower mold 1. Then the ultrasonic welding machine drives the welding head 2 to lower its height and contact the surface of the plastic part to perform welding. When the welding head 2 is lowered for welding, the cross plate 21 and the magnet 211 will also lower their height and approach the top of the iron plate 41. After the welding is completed, the welding head 2 is driven to rise to a high position. When the height is high, the horizontal plate 21 containing the magnet 211 will also be driven to rise. Under the action of the magnet 211 adsorbing the iron plate 41, the vertical plate 4 can cooperate with the connecting plate 111 to drive the support plate 11 in the mold groove to rise, so as to support and push out the welded plastic parts, so as to facilitate the removal of the welded parts. After the support plate 11 rises to the highest height and the connecting rod hits the upper surface of the through-hole 12, the support plate 11 can no longer rise, and the welding head 2 continues to drive the horizontal plate 21 and the magnet 211 to rise, and finally the magnet 211 can no longer continue to adsorb the iron plate 41, so that the support plate 11 and the iron plate 41 and other structures are lowered, and the support plate 11 falls into the mold groove again.
