Abstract
The utility model discloses a linear rack core-pulling mechanism of a plastic elbow mould. The linear rack core-pulling mechanism of the plastic elbow mould comprises a mould lower cavity and a core, wherein a supporting board is arranged at the bottom of the lower cavity and is arranged on a mould leg, and the mould leg is arranged on a bottom board; and the core comprises an elbow core and a linear core, wherein a guide post is arranged at the outer end of the elbow core, a support is arranged at one side of the supporting board, and the guide post is connected with the support by penetrating through the linear core. The linear rack core-pulling mechanism of the plastic elbow mould is characterized in that the outer end of the linear core is connected with an external sliding block, the guide post penetrates through the external sliding block, a linear rack is arranged at the bottom of the external sliding block, an oil motor is arranged at the bottom of the support, a gear is arranged on a rotating shaft of the oil motor, and the gear is meshed with the linear rack. According to the linear rack core-pulling mechanism of the plastic elbow mould, disclosed by the utility model, the oil motor drives a gear rack to do linear sliding, thus the linear core is driven to carry out the core pulling, the size is small, the cost is saved, and the resource is saved.
Description
Technical field
The utility model relates to a kind of plastic bend tube mould linear gear rack core-pulling mechanism, belongs to the mould of plastics field.
Background technology
Adopt mould of plastics to produce plastic product; Plastic bend tube etc. for example; The primary structure of mould comprises upper impression and lower impressions, between upper impression and the lower impressions fuse is arranged, and described fuse comprises that elbow fuse and straight line fuse form; When the bend pipe demoulding, at first to elbow fuse and straight line fuse be loosed core.Prior art is loosed core to the straight line fuse and is generally adopted the oil cylinder linear drives to drive, still, because oil cylinder is installed in the back of slide block; The length of oil cylinder is long; And the elbow fuse generally all adopts rotation to loose core when loosing core, and has so just increased the radius of rotation, and machinery (injection machine) that must be very big could be produced; So just increase production cost, caused the wasting of resources.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, provides a kind of employing oil motor driven gear rack linear to slide, and drives the straight line fuse and looses core, and volume is little, and cost is economized, the plastic bend tube mould linear gear rack core-pulling mechanism that economizes on resources.
The technical scheme of the utility model plastic bend tube mould linear gear rack core-pulling mechanism is: comprise mould lower impressions and fuse, the lower impressions bottom is equipped with gripper shoe, and gripper shoe is installed on the mould pin; The mould pin is installed on the base plate, and described fuse comprises elbow fuse and straight line fuse, and the outer end of elbow fuse is equipped with guide pillar; At a side mounting bracket of gripper shoe, guide pillar passes the straight line fuse and is connected with support, it is characterized in that described straight line fuse outer end connects outer slide; Guide pillar passes outer slide, in the bottom of outer slide linear gear rack is installed, and oil motor is installed in the bottom of support; On the turning cylinder of oil motor gear is installed, gear is meshed with linear gear rack.
The plastic bend tube mould linear gear rack core-pulling mechanism of the utility model adopts oil motor to drive, and oil motor can be installed in the bottom of support, reduces the radius of turn of elbow fuse when loosing core, and volume is little, is fit to middle-size and small-size injection machine production, saves the cost input.Linear gear rack is fixed on the bottom of outer slide, and during work, the oil motor driven gear rotates; Because gear is meshed with linear gear rack, and the guide pillar of elbow fuse outer end also passes outer slide, therefore; Be the equal of that oil motor drive outer slide slides on guide pillar, the action of loosing core is stable, reliable.
The plastic bend tube mould linear gear rack core-pulling mechanism of the utility model, described outer slide bottom is shaped on guide runner, and slider guide is installed on the support, and slider guide matches with guide runner, has had guide runner and slider guide to cooperate, and outer slide slides steadily.
Description of drawings
Fig. 1 is the utility model plastic bend tube mould linear gear rack core-pulling mechanism structural representation;
Fig. 2 is the linear gear rack and the gears engaged sketch map of the utility model.
The specific embodiment
The utility model relates to a kind of plastic bend tube mould linear gear rack core-pulling mechanism, like Fig. 1, shown in Figure 2, comprises mould lower impressions 1 and fuse; Lower impressions 1 bottom is equipped with gripper shoe 4, and gripper shoe 4 is installed on the mould pin 5, and mould pin 5 is installed on the base plate 6; Described fuse comprises elbow fuse 2 and straight line fuse 3, and the outer end of elbow fuse 2 is equipped with guide pillar 7, at a side mounting bracket 8 of gripper shoe 4; Guide pillar 7 passes straight line fuse 3 and is connected with support 8, it is characterized in that described straight line fuse 3 outer ends connect outer slide 9, and guide pillar 7 passes outer slide 9; Linear gear rack 10 is installed in bottom at outer slide 9; Oil motor 11 is installed in the bottom of support 8, and gear 12 is installed on the turning cylinder of oil motor 11, and gear 12 is meshed with linear gear rack 10.This programme adopts oil motor to drive, and oil motor 11 can be installed in the bottom of support 8, reduces the radius of turn of elbow fuse 2 when loosing core, and volume is little, is fit to middle-size and small-size injection machine production, saves the cost input.Linear gear rack 10 is fixed on the bottom of outer slide 9; During work, oil motor 11 driven gears 12 rotate, because gear 12 is meshed with linear gear rack 10; And the guide pillar 7 of elbow fuse 2 outer ends also passes outer slide 9; Therefore, be the equal of that oil motor 11 drive outer slides 9 slide on guide pillar 7, the action of loosing core is stable, reliable.Described outer slide 9 bottoms are shaped on guide runner 13, and slider guide 14 is installed on the support 8, and slider guide 14 matches with guide runner 13, have had guide runner and slider guide to cooperate, and outer slide slides steadily.
