Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a quick mold change device for injection molding machines based on automatic adjustment. Background Technology

[0002] An injection molding machine, also known as an injection molding machine or injection molding machine, is a primary molding device that uses plastic molds to produce plastic products of various shapes from thermoplastic or thermosetting plastics. Injection molding machines require quick mold changes during operation, which necessitates the use of a mold changing device.

[0003] Existing patent CN222096800U discloses a quick mold change device for an injection molding machine. In this patent, the mold is placed in the mold change clamp of the injection molding machine. A lifting mechanism can drive a winding wheel to rotate, which in turn drives a transmission rope to move. The transmission rope, through the mold change clamp, can lift and lower the mold. A power mechanism can drive a chain to rotate, which in turn drives a secondary sprocket to rotate. The secondary sprocket drives a rotating shaft to rotate, which in turn drives a support frame to rotate. The support frame, through the mold change clamp, can move the mold. However, in the above patent, the mold is lifted and lowered by using a transmission rope to move the mold change clamp. During this process, the mold swings along the transmission rope, which can easily collide with the injection molding machine or the operator. If it collides with the injection molding machine, it can easily damage the mold. If the mold collides with the operator, it can easily cause injury. There are certain safety hazards in the quick mold change process. Furthermore, the positions of the two transmission ropes are relatively fixed and cannot be adjusted, resulting in poor flexibility and adaptability. Utility Model Content

[0018] 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.

[0019] like Figures 1-4 As shown, a quick mold change device for an injection molding machine based on automatic adjustment includes a base 1, a counterweight support column 2 on the base 1, and a horizontal plate 4 mounted on the upper end of the counterweight support column 2 via a rotating structure 3. An adjustment structure 5 is provided on the horizontal plate 4, and a first multi-stage telescopic cylinder 6 and a second multi-stage telescopic cylinder 7 are respectively mounted on the horizontal plate 4 and the adjustment structure 5. A connecting rod is provided at the lower end of the first multi-stage telescopic cylinder 6 and the second multi-stage telescopic cylinder 7, and a pneumatic gripper 8 is fixed to the lower end of the connecting rod. A vision camera 9 is provided on the horizontal plate 4, and a mounting sleeve 10 is provided on the first multi-stage telescopic cylinder 6, with a sensor 11 fixed on the mounting sleeve 10 and a fixing screw 12 on the mounting sleeve 10. A caster wheel 13 is provided on the lower surface of the base 1, and the base 1 is fixedly connected to the counterweight support column 2.

[0020] During rapid mold changeover of injection molding machines, the device is moved to a suitable location using the casters 13 on the base 1. A vision camera 9 measures and feeds back the mold length, while a sensor 11 on the mounting sleeve 10 detects the distance from the second multi-stage telescopic cylinder 7. Combined with the mold length information from the vision camera 9, the position of the second multi-stage telescopic cylinder 7 relative to the first multi-stage telescopic cylinder 6 can be adjusted using the adjustment structure 5, thus achieving automatic adjustment. After the distance between the two multi-stage telescopic cylinders is adjusted, the distance between the pneumatic grippers 8 is adapted to the corresponding mold. Upon activation of the multi-stage telescopic cylinders, the pneumatic grippers 8 descend to contact the mold and clamp it. Once clamped, the multi-stage telescopic cylinders retract, lifting the mold via the pneumatic grippers 8. The moving device then transports the mold. After the mold reaches the appropriate position, the rotating structure 3 is activated to rotate the horizontal plate 4, the adjustment structure 5, the multi-stage telescopic cylinders, and the mold, allowing for mold replacement. This achieves rapid mold changeover.

[0021] According to the above implementation scheme, the rotating structure 3 includes a rotating plate 301, a driven bevel gear 302, a rotating rod 303, a mounting frame 304, a first servo motor 305, and a driving bevel gear 306. The rotating plate 301 is fixedly connected to the driven bevel gear 302. The rotating rod 303 is connected to the driven bevel gear 302, and the lower end of the rotating rod 303 is rotatably mounted on the counterweight support column 2. The mounting frame 304 is fixed on the counterweight support column 2. The first servo motor 305 is mounted on the mounting frame 304. The driving bevel gear 306 is connected to the first servo motor 305, and the driving bevel gear 306 is meshed with the driven bevel gear 302.

[0022] When using the rotating structure 3, the first servo motor 305 on the mounting bracket 304 is started. The first servo motor 305 drives the active bevel gear 306 to rotate, thereby driving the driven bevel gear 302 to rotate. The driven bevel gear 302 then drives the rotating plate 301 and the rotating rod 303 to rotate on the counterweight support column 2, thereby achieving the purpose of rotating and adjusting the horizontal plate 4, the adjusting structure 5, and the two multi-stage telescopic cylinders. After the adjustment is completed, the mold can be loaded and unloaded.

[0023] According to the above implementation scheme, the adjustment structure 5 includes a movable plate 501, a guide rod 502, an adjustment seat 503, a nut seat 504, a support seat 505, a fixed plate 506, a lead screw 507, a second servo motor 508, and a support rod 509. The movable plate 501 is fixedly connected to the guide rod 502, and the guide rod 502 is movably connected to the horizontal plate 4. The adjustment seat 503 and the nut seat 504 are fixedly connected, and the adjustment seat 503 is set on the horizontal plate 4. The support seat 505 is fixed on the horizontal plate 4. The fixed plate 506 is fixed to the movable plate 501. One end of the lead screw 507 is connected to the fixed plate 506, and the other end passes through the adjustment seat 503 and the nut seat 504. The second servo motor 508 is fixed to the fixed plate 506, and the second servo motor 508 is connected to the lead screw 507. The support rod 509 is fixed to the end of the lead screw 507, and the support rod 509 passes through the support seat 505.

[0024] When adjusting the position of the second multi-stage telescopic cylinder 7, the second servo motor 508 on the fixed plate 506 is activated. The lead screw 507 rotates accordingly. Under the action of the lead screw 507 and the nut seat 504, the lead screw 507 is displaced relative to the adjusting seat 503, thereby causing the movable plate 501 to move relative to the horizontal plate 4 via the guide rod 502, achieving the purpose of adjusting the second multi-stage telescopic cylinder 7. During the rotation and movement of the lead screw 507, the support rod 509 at the end of the lead screw 507 rotates and moves on the support seat 505. The support seat 505, in conjunction with the support rod 509, provides support for the lead screw 507, ensuring the rotational stability of the lead screw 507. The structure is simple and the performance is excellent.

[0025] It should be noted that a first multi-stage telescopic cylinder 6 and a second multi-stage telescopic cylinder 7 are respectively installed on the horizontal plate 4 and the adjustment structure 5. The pneumatic gripper 8 is installed using a rigid structure, which can ensure that the mold will not swing after being clamped, avoiding damage caused by the mold swinging and impact, and protecting the staff. Through the adjustment structure 5, the position of the second multi-stage telescopic cylinder 7 relative to the first multi-stage telescopic cylinder 6 can be adjusted according to the actual situation, thereby changing the position of the pneumatic gripper 8 below. It is suitable for different molds and has high flexibility and adaptability. The adjustment is carried out by a second servo motor 508, a lead screw 507 and a nut seat 504. It can be adjusted arbitrarily within the adjustable range and the stability after adjustment can be guaranteed. A support rod 509 is set at the end of the lead screw 507, which works with the support seat 505 to improve the stability of the lead screw 507.
