Intelligent vertical mold clamping equipment

Abstract

The invention discloses an intelligent vertical mold clamping device, which belongs to the technical field of vertical mold clamping machine structures. A connected locking structure is arranged at the output end of a flip cylinder, and the locking action of the locking structure is controlled by power failure. When the device operates normally, the electromagnet always adsorbs the locking plate to keep the locking plate away from the locking roller. When the power is off, the locking plate can be quickly clamped into the locking roller to stop the locking roller from rotating, and the gear connected to the locking wheel can stop rotating, and the sliding rod engaged with the gears is directly stuck. When the power is off, the sliding rod directly limits the telescopic movement of the flip cylinder, so as to ensure that the upper workbench pulled by the flip cylinder always maintains the position when the power is off, thereby avoiding displacement of the upper workbench due to long-term power failure, and avoiding device collision and program error caused by the continuous operation of the device when a power is suddenly supplied.

Description

Technical Field

[0001] The invention belongs to the technical field of vertical mold clamping machine structures, and in particular relates to an intelligent vertical mold clamping device. Background Art

[0002] The mold clamping machine is a special testing equipment for mold research and matching. It is mainly used in the later stage of mold production to align the mold up and down and achieve mold clamping through high pressure. Its structure refers to Figure 1 Its main working parts are the upper workbench 3 and the lower workbench 7. The slide 2 is driven to move by the main oil cylinder 1, and the upper workbench 3 on the slide 2 is pressed downward to close the two halves of the mold 8 magnetically attracted by the upper workbench 3 and the lower workbench 7. In order to facilitate the installation of the mold 8 and take safety into consideration, the upper workbench 3 is set as a structure hinged to the slide 2, and the upper workbench is pulled by the flipping oil cylinder 4 and flipped onto the slide 2, so that the upper workbench 3 can be flipped and placed face up on the lower platform 7.

[0003] Due to its large size and weight, this equipment needs to be equipped with power-off protection to prevent the equipment from slipping and falling due to sudden power failure during the flipping process of the upper workbench 3. When the power suddenly fails, if the upper workbench 3 is still in the flipping process, the flipping cylinder 4 loses power, and the upper workbench 3 will rotate downward due to the disappearance of hydraulic pressure. A long power failure will cause the position of the upper workbench to be different from that before the power failure. If the power is suddenly restored, the continued operation of the equipment may cause equipment collision or program errors, or even damage to parts. Summary of the invention

[0024] like Figures 1 to 7 As shown, the present invention provides an intelligent vertical mold clamping device, including a main oil cylinder 1 and a slide 2 arranged at the bottom end of the main oil cylinder 1, the edge of the slide 2 is hinged with an upper workbench 3, and the slide 2 is also provided with a flip cylinder 4 for flipping the upper workbench 3, as shown in FIG. Figure 2 , Figure 3 and Figure 4 As shown, the output end of the flip cylinder 4 is fixed with a hook head 53 for hooking the upper workbench 3, and a positioning frame 5 is fixed on the outer side of the flip cylinder 4. The positioning frame 5 is fixed by screws. The positioning frame 5 is provided with a rotating shaft 51 rotatably connected to the slide 2. The positioning frame 5 is rotatably set in the slide 2 through the rotating shaft 51. With the extension and retraction of the flip cylinder 4, the upper workbench 3 rotates around the hinge point of the slide 2 shown. A sliding rod 52 is slidably provided on the positioning frame 5, and one end of the sliding rod 52 is fixedly connected to the hook head 53. A guide hole is opened on the fixing frame, and the sliding rod 52 is slidably set in the guide hole, so that the moving direction of the sliding rod 52 is the same as the extension and retraction direction of the flip cylinder 4. Figure 4 and Figure 5 As shown, gears 54 are respectively meshed on both sides of the slide rod 52, and the gears 54 are rotatably arranged on the positioning frame 5. The rotating shaft 51 of the gear 54 is perpendicular to the telescopic direction of the flip cylinder 4. Racks 521 meshing with the gears 54 are respectively arranged on both sides of the slide rod 52. The gear teeth on the two racks 521 are staggered relative to the extension direction of the slide rod 52. The gear 54 is coaxially provided with a locking roller 55. The locking roller 55 is made of anti-slip plastic material. The shape of the locking roller 55 is as shown in FIG. Figure 4 The positioning frame 5 is also provided with a movably locking plate 56, the structure of the locking plate 56 is as shown Figure 6 The locking plate 56 is translated on the positioning frame 5 through the guide column. The locking plate 56 is provided with a truncated cone-shaped locking hole 561, and the inner side of the locking hole 561 is also provided with an anti-slip plastic layer; a locking spring 57 is provided between the locking plate 56 and the positioning frame 5, Figure 4The contact surface between the positioning frame 5 and the locking plate 56 is provided with a recessed hole 59, and the locking spring 57 partially extends into the recessed hole 59. Figure 7 , an electromagnetic plate 58 is provided on the side of the positioning frame 5 facing the locking plate 56, and the electromagnetic plate 58 is arranged around the give way countersunk hole 59. The electromagnetic plate 58 sucks the locking plate 56 onto the positioning frame 5, and at this time, the locking spring 57 is compressed in the countersunk hole by the locking plate 56. When the circuit of the electromagnetic plate 58 is set, the circuit of the electromagnetic plate 58 is directly connected in series to the power output route of the entire device. When the device suddenly loses power, the electromagnetic plate 58 will be directly powered off, and the locking spring 57 pushes the locking plate 56 away from the positioning frame 5, and the locking hole 561 is inserted into the locking roller 55. Under the action of friction, the locking plate 56 stops the locking roller 55 from rotating, and the two gears 54 no longer rotate. The gear 54 The rack 521 is stuck, and the hook head 53 linked to the rack 521 hooks the upper workbench 3 to keep the workbench in the same position when the power is off; in this structure, the staggered double gears 54 are engaged, and when the gear 54 stops rotating at any time, the rack 521 can be quickly stuck to avoid relative movement between the rack 521 and the gear 54, and the two gears 54 can also limit the lateral swing of the slide rod 52; the tooth shape and even the number of teeth of the two gears 54 can be set to different values, further ensuring that the gear 54 can quickly lock the rack 521 under the condition of restricted rotation, and the conical locking roller 55 can guide the locking plate 56 to be inserted, so that the locking hole 561 forms a larger surface contact with the locking roller 55, thereby increasing the friction stress between the locking roller 55 and the locking plate 56.

[0025] The vertical mold clamping equipment of this structure is provided with a locking structure connected at the output end of the flip cylinder. The locking action of the locking structure is controlled by power failure. When the equipment is operating normally, the electromagnet always adsorbs the locking plate 56 to keep the locking plate 56 away from the locking roller 55. When the power is off, the locking plate 56 can be quickly clamped into the locking roller 55 to stop the locking roller 55 from rotating. The gear 54 connected to the locking wheel can stop rotating, and the sliding rod 52 engaged with the gear 54 is directly stuck. When the power is off, the sliding rod 52 directly limits the telescopic movement of the flip cylinder 4 to ensure that the upper workbench 3 pulled by the flip cylinder 4 always maintains the position when the power is off, avoiding the displacement of the upper workbench 3 due to long-term power failure, and avoiding equipment collision and program errors caused by the continuous operation of the equipment when the power is suddenly on.

[0026] In a further solution, Figure 4As shown, the gear 54 is coaxially provided with a rotating shaft 541, and bearing blocks 542 are provided at both ends of the rotating shaft 541. The bearing blocks 542 are movably arranged on the positioning frame 5 so that the moving direction of the gear 54 is perpendicular to the extending direction of the sliding rod 52. A clamping spring 543 is also provided between the bearing block 542 and the positioning frame 5. The clamping spring 543 presses against the bearing block 542 to make the gear 54 away from the sliding rod 52. When the gear 54 is away from the extreme position of the sliding rod 52, the gear 54 is still engaged with the sliding rod 52. The gear 54 is provided with a bevel annular groove 544 with a triangular cross-section on one side of the locking plate 56. A clamping column 562 is fixed on the locking plate 56. When the locking plate 56 is away from the positioning frame 5, the clamping column 562 presses into the bevel annular groove 544 to make the gear 54 close to the sliding rod 52.

[0027] This structure is used to further lock the slide rod 52. When the locking plate 56 is close to the locking roller 55, the clamping column 562 presses into the bevel ring groove 544. Under the push of the locking spring 57, the clamping column 562 moves along the bevel of the bevel ring groove 544 and pushes the gear 54 toward the slide rod 52. The two gears 54 clamp the two sides of the slide rod 52, which can further ensure that the gear 54 is engaged with the slide rod 52 and avoid slight displacement of the slide rod 52.

[0028] In a further solution, Figure 3 As shown, an electric cylinder 6 is also provided on the positioning frame 5, and a connecting plate 61 is fixedly connected to the output end of the electric cylinder 6. A connecting column 62 is fixedly provided on the connecting plate 61, and the other end of the connecting column 62 is fixedly connected to the locking plate 56. The electric cylinder 6 works to make the locking plate 56 close to the positioning frame 5.

[0029] This structure is used to return the locking plate 56 to its original position when power is supplied. When power is restored, the electric cylinder 6 can work to push the locking plate 56 back and away from the locking roller 55. The locking roller 55 loses the restriction of friction, and the flip cylinder 4 can continue to work to flip the upper workbench 3. This structure can realize the rapid return of the locking structure without manual return, avoid the locking structure from jamming the equipment after power is supplied, and ensure the rapid recovery of the equipment status after power is supplied.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
