Abstract
A core-pulling mechanism rotating along an arc rack for a plastic bend mold comprises a mold lower cavity and a core, wherein a support plate is installed at the bottom of the lower cavity, the support plate is installed on mold feet, and the mold feet are installed on the bottom plate. The core comprises an elbow core and a linear core, wherein a guiding column is arranged at the outer end of the elbow core and penetrates through the linear core which is driven to perform core pulling by an outer sliding block. The core-pulling mechanism rotating along the arc rack is characterized in that a fixing pin is installed on the support plate, a rotating support plate is arranged on the fixing pin, a fixing support is installed on the rotating support plate, the outer sliding block is arranged on the fixing support which is connected with the guiding column, an oil motor is installed at the bottom of the rotating support plate, a rotating shaft of the oil motor is connected with a gear, and an arc rack is installed on the edge of the support plate and matched with the gear. By means of the technical scheme, the oil motor is used for driving, and the core-pulling mechanism rotates along the arc rack for demolding, and is stable and reliable in movement, small in abrasion and high in accuracy and working efficiency.
Description
Technical field
The utility model relates to a kind of plastic bend tube mould camber line tooth bar rotation 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 elbow fuse and is generally adopted the oil cylinder wobble drive, and the moment that oil cylinder needs is very big, and wearing and tearing are big, low precision, inefficiency.
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 to drive, and along the demoulding of camber line tooth bar rotating operation, action is stable, and it is little wear and tear, and precision is high, and the plastic bend tube mould camber line tooth bar of high efficiency rotates core-pulling mechanism.
The technical scheme of the utility model plastic bend tube mould camber line tooth bar rotation 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; Guide pillar passes the straight line fuse, and the straight line fuse is driven by outer slide looses core, and it is characterized in that installing and fixing pin on the described gripper shoe; The rotation support plate is set on the steady pin, mounting and fixing bracket on the rotation support plate, outer slide is arranged on the fixed support; Guide pillar connects fixed support, and oil motor, the turning cylinder connection gear of oil motor are installed in described rotation support plate bottom; At the installation camber line tooth bar along the limit of gripper shoe, the camber line rack and pinion is meshed.
The plastic bend tube mould camber line tooth bar rotation core-pulling mechanism of the utility model elbow fuse, straight line fuse and outer slide are arranged on the fixed support, and fixed support is installed on the rotation support plate; Oil motor is installed in bottom at the rotation support plate, and the turning cylinder connection gear of oil motor is at the installation camber line tooth bar along the limit of gripper shoe; The camber line rack and pinion is meshed; When loosing core, the oil motor driven gear rotates, and gear is meshed with the camber line tooth bar; Be exactly that gear moves along the camber line tooth bar; The driven rotary support plate rotates around steady pin, makes to be installed in fixed support and outer slide, straight line fuse and the elbow fuse of rotation on the support plate and to rotate the demoulding of from bend pipe, loosing core of elbow fuse.This programme adopts oil motor to drive, and along the demoulding of camber line tooth bar rotating operation, action is stable, reliable, and it is little to wear and tear, and precision is high, high efficiency.
