Disclosure of Invention
The utility model aims to solve the problems in the prior art, and provides a sliding block mechanism of a multicolor rotary die, which aims to solve the technical problems that: how to solve the problem that the inclined guide post in the existing multicolor rotary die can not quickly drive the sliding block to move.
The aim of the utility model can be achieved by the following technical scheme:
the utility model provides a slider mechanism of polychrome rotary die, polychrome rotary die includes oblique guide pillar, this slider mechanism is including the slider that has ejecting piece, the interior bar through-hole that can supply oblique guide pillar to wear to establish of seting up of slider, the both sides pore wall of bar through-hole all outwards sunken formation installation cavity, a serial communication port, all articulate there is the atress piece in the installation cavity, two atress pieces keep away from the tip of pin joint one end and all have the spacing portion that removes along the width direction of bar through-hole, all be equipped with in the installation cavity and have the spacing spring that pushes the trend in the bar through-hole with spacing portion all the time, can promote spacing portion towards the outside removal of bar through-hole and step down when the one end motion of bar through-hole to one side, the one end that spacing portion is close to the pin joint can press on oblique guide pillar and make the lateral wall of oblique guide pillar laminating mutually with the pore wall of bar through-hole one end.
Working principle: before carrying out the injection molding to the die cavity II of polychrome rotary die, the oblique guide pillar can insert in the bar through-hole, and along with secondary compound die, the one end motion of oblique guide pillar orientation bar through-hole is gone up to the side wall of oblique guide pillar can promote spacing portion outside the bar through-hole and remove and give way, make oblique guide pillar can pass spacing portion, the side wall of oblique guide pillar is laminated with the pore wall of bar through-hole one end to spacing portion one end that is close to the pin joint to the continuous motion of oblique guide pillar, after the completion of the second injection molding, polychrome rotary die sinking, oblique guide pillar can only vertical movement under the pressure of spacing portion at this moment, thereby drive slider lateral shifting, because the tip arch of slider is formed with ejecting piece, can be ejecting with the bicolor plastic piece after the shaping when sliding lateral shifting, thereby the drawing of patterns of the die after the shaping of being convenient for.
Because the atress piece is articulated in the installation cavity, therefore, when the oblique guide pillar promotes spacing portion and moves outward towards the bar through-hole, spacing portion swings along the pin joint of atress piece, spacing portion is the tip that keeps away from pin joint one end of atress piece this moment, therefore it is farther from the pin joint, the arm of force is longer, consequently, make the oblique guide pillar more laborsaving and promote spacing portion easily, spacing portion realizes stepping down it, when the lateral wall that moves to the oblique guide pillar and the pore wall of bar through-hole one end paste, spacing portion can reset under spacing spring's elasticity, and can press the oblique guide pillar on the pore wall of bar through-hole one end, thereby realize the spacing to oblique guide pillar is stable, avoid oblique guide pillar reverse motion and promote spacing portion to move towards the direction outside the bar through-hole, thereby make the oblique guide pillar can be quick motion to press on the pore wall of bar through-hole, and the oblique guide pillar can be under spacing effect of spacing portion stable drive the slider removal, slider mechanism's convenience and stability have been promoted.
