Description

Technical Field

[0001] The utility model relates to the technical field of extrusion dies, in particular to an extrusion die with buffering and shock absorbing functions. Background Art

[0002] A mold is a tool that uses a specific shape to shape the solid and liquid blank into a part with a certain shape and size under the action of external force. Molds are extremely widely used in forging, stamping, powder metallurgy pressing, pressure casting, and compression and injection molding of engineering plastics, rubber, ceramics and other products. The mold is generally divided into two parts, which can be divided into movable mold and fixed mold according to the motion state, and divided into concave mold and convex mold according to the shape. There are many types of molds, including steel molds, iron molds, tin molds, wooden molds, gypsum molds, mud molds, etc. Among them, the steel mold is the most used, and it is known as the "mother of industry".

[0003] For example, Chinese patent (CN214983521U) discloses a rapid prototyping mold with a shock absorbing function, comprising a support base, support rods are arranged on both sides of the support base, a receiving top plate is arranged on the top of the support rod, a lower mold seat is arranged on the top of the support base, an upper mold seat is arranged on the upper end of the lower mold seat, symmetrical second connecting rods are arranged on both sides of the bottom end of the lower mold seat, and symmetrical fixing rods are arranged on the inner side of the second connecting rods. The rapid prototyping mold with a shock absorbing function described in the utility model belongs to the field of rapid prototyping mold technology, and the upper mold seat is buffered by the first spring to reduce the pressure on the upper mold seat; the lower mold seat is effectively buffered by the structure of the movable block and the second spring squeezing the fixing rod. After the stamping is completed, the lower mold seat is pushed upward by the shock absorbing spring and the first connecting rod at the same time to reset it for the convenience of the next operation.

[0004] The above scheme also has the following technical defects. After the first connecting rod of the above scheme impacts the first spring, the first spring will be deformed. When the impact force disappears, the first spring will rebound against the first connecting rod, thereby causing the first connecting rod to shake. Similarly, after the second connecting rod compresses the second spring, the deformation of the second spring recovers, causing the second connecting rod to shake, thereby driving the mold to shake, causing the upper mold seat to repeatedly extrude the workpiece. Based on this, an extrusion mold with buffering and shock absorbing function is proposed. Utility Model Content

[0032] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller.

[0033] The working principle of the above embodiment is:

[0034] When the extrusion device extrude the workpiece, the extrusion device drives the buffer rod 5 to move downward, and the buffer rod 5 enters the buffer groove 401. Then the buffer rod 5 drives the third rubber pad to hit the inclined plate 407. The inclined plate 407 drives the moving rod 406 and the moving plate 405 to move to both sides. The moving plate 405 squeezes the spring 404. When the buffer rod 5 moves to the bottom of the buffer groove 401, the third rubber pad collides with the first rubber pad 402. The first rubber pad 402 and the third rubber pad are deformed to buffer the impact force. At the same time, the inclined plate 407 enters the installation groove 403 under the action of the deformation recovery of the spring 404. When the buffer rod 5 vibrates upward, it drives the third The rubber pad collides with the second rubber pad 408, thereby buffering again, so that the buffer rod 5 reduces the shaking. When the buffering is completed, the pull rod 409 is pulled to take the buffer rod 5 out of the buffer groove 401; when the processing is completed, the motor 601 is started, and the output shaft of the motor 601 rotates to drive the first screw 602 to rotate. The first screw 602 drives the driving wheel to rotate, and the driving wheel drives the transmission belt to transmit. The transmission belt drives the second screw 603 to rotate, and the first screw 602 and the second screw 603 drive the lifting plate 605 to move upward together, and the lifting plate 605 drives the lifting rod 606 and the push plate 607 to move upward, and the push plate 607 pushes the workpiece out.
