Description

Plastic tray mould forklift hole slide block gear rack linkage core-pulling mechanism

Technical Field

The utility model relates to a plastics tray mould fork truck hole slider rack and pinion linkage mechanism of loosing core belongs to the injection mold field.

Background

The plastic product such as a plastic tray and the like is produced by adopting an injection mold, and the plastic tray is provided with a forklift hole for the fork of a forklift to stretch into. After the plastic tray is injection molded, the forklift holes need to be firstly subjected to core pulling and then can be ejected out for demolding. The fork truck hole on the plastics tray has two, and prior art respectively designs into a length one for one with two fork truck hole sliders, and two liang of length are to inserting the cooperation, and during the core pulling, every slider is respectively by a hydro-cylinder drive and is loosed core, and its shortcoming of existence has: one, the required oil cylinders are more, and the cost is high; secondly, the core-pulling action precision of the oil cylinder is poor, and the core-pulling time error of each sliding block is large, so that the mold clamping is easy to occur; meanwhile, when each sliding block is reset, collision is easy to happen, damage is caused, and production efficiency is affected by shutdown and maintenance.

Disclosure of Invention

The utility model aims at overcoming prior art's shortcoming, provide one kind and adopt servo motor to drive, two syntropy slider linkages are loosed core, and the precision that resets is high, reduces the collision, saves the cost, improves production efficiency's plastics tray mould fork truck hole slider rack and pinion linkage mechanism of loosing core.

The utility model discloses plastic tray mould fork truck hole slider rack and pinion linkage mechanism of loosing core's technical scheme is: the die comprises a fixed die compound plate and a movable die compound plate, wherein a base plate is arranged below the fixed die compound plate, a fixed die plate is arranged below the base plate, a fixed die insert is arranged in the fixed die plate, a die pin is arranged on the movable die compound plate, a movable die plate is arranged on the die pin, a movable die insert is arranged on the movable die plate, and two long fork hole sliders and short fork hole sliders are respectively arranged between the movable die insert and the fixed die insert in the same direction. A gear is arranged on an output shaft of the servo motor and meshed with a rack, and the rack is connected with a band.

The utility model discloses a plastic pallet mould fork truck hole slider rack and pinion linkage mechanism of loosing core, when loosing core, drive the gear by servo motor, the gear drives the rack and outwards slides in the rack slide to drive band cunning outward, band drive long fork hole slider and short fork hole slider loose core, loose core action is simple, stable; meanwhile, the bottom surfaces of the upper part and the lower part of the edging are respectively connected with a T-shaped guide block, and the T-shaped guide blocks are matched with the slide ways, so that the edging slides outwards more stably; and adopt servo motor to drive, make the rack accurate in rack slide stroke, especially when reseing, can effectively prevent that long fork hole slider and two short fork hole sliders from colliding with other parts of mould, extension slider life improves production efficiency.

fig. 2 is a schematic top view of the plastic pallet mold core-pulling mechanism of the present invention.

Detailed Description

The utility model relates to a plastic pallet mould forklift hole slider gear rack linkage core pulling mechanism, as shown in figure 1 and figure 2, comprising a fixed mould compound plate 1 and a movable mould compound plate 2, a base plate 3 is arranged under the fixed mould compound plate, a fixed mould plate 4 is arranged under the base plate, a fixed mould insert 5 is arranged in the fixed mould plate, a mould foot 6 is arranged on the movable mould compound plate, a movable mould plate 7 is arranged on the mould foot, a movable mould insert 8 is arranged on the movable mould plate, two long fork hole sliders 9 and two short fork hole sliders 10 are respectively arranged between the movable mould insert and the fixed mould insert in the same direction, the outer ends of the two long fork hole sliders 9 and the two short fork hole sliders 10 are respectively connected with a band 11, the upper part and the lower part of the band 11 are respectively connected with a T-shaped guide block 12, a slide 13 is respectively connected on the outer wall of the corresponding movable mould plate 7, the T-shaped guide block 12 is matched with the slide 13, wherein, the long slide on one side of the long fork hole slider 9 and the short slide on one side of the short hole slider 10, meanwhile, a rack sliding seat 15 is arranged in the middle of the outer walls of two sides of the movable template 7, a rack 16 is arranged in the rack sliding seat 15 in a sliding mode, a servo motor 17 is arranged on the rack sliding seat 15, a gear 18 is arranged on an output shaft of the servo motor, the gear 18 is meshed with the rack 16, and the rack 16 is connected with the band 11. During core pulling, the servo motor 17 drives the gear 18, the gear drives the rack 16 to slide outwards in the rack sliding seat 15, so that the band 11 is driven to slide outwards, the band 11 drives the long fork hole sliding block 9 and the short fork hole sliding block 10 to core, and the core pulling action is simple and stable; meanwhile, the bottom surfaces of the upper part and the lower part of the band 11 are respectively connected with a T-shaped guide block 12, and the T-shaped guide blocks 12 are matched with the slide ways 13, so that the outward sliding of the band 11 is more stable; and adopt servo motor to drive, make the rack accurate in rack slide stroke, especially when reseing, can effectively prevent that long fork hole slider and two short fork hole sliders from colliding with other parts of mould, extension slider life improves production efficiency.
