Background

As the appearance requirements of products are gradually improved, more and more plastic products need multicolor injection molding, in the multicolor injection molding process, a special multicolor rotary injection mold, such as a bicolor rotary injection mold, is needed, as shown in fig. 1 and 2, the mold comprises an upper mold 9 and a lower mold 10, the upper mold 9 and the lower mold 10 are assembled to form a cavity 101, a sliding block 3 is arranged between the upper mold 9 and the lower mold 10, one side of the cavity is injected, the mold is opened after the injection molding is completed, the upper mold 9 or the lower mold 10 is rotated, and after the mold is assembled again, the other side of the cavity is injected.

The traditional multicolor rotary injection mold can eject the first molded plastic part through the matching action of the inclined ejector rod and the sliding block after the first mold is opened, so that the first molded plastic part can not be stably positioned and placed during the second mold closing, and the injection molding of the multicolor mold is affected.

In response to the above-mentioned problems, various slide mechanisms for multi-color rotary molds have been developed:

as disclosed in chinese patent application CN205674437U, a core pulling mechanism for producing a double-color mold for automobile lamp decoration is disclosed, the double-color mold comprises a fixed mold and a movable mold, the fixed mold and the movable mold are relatively arranged and can form two cavities, one side of the fixed mold is provided with an inclined guide pillar, a core pulling slide block is arranged on the movable mold, a through hole is formed in the core pulling slide block, the inclined guide pillar can be inserted into the through hole, a spring block facing the through hole is arranged in the core pulling slide block, a spring for enabling the spring block to move towards the through hole is arranged between the spring block and the core pulling slide block, an inclined surface abutted against the side surface of the inclined guide pillar is arranged on the side surface of the spring block, and a locking block capable of resetting and locking the core pulling slide block is also arranged on the fixed mold.

The structure is provided with the spring rebound elastic block, so that the phenomenon that the inclined guide post slides out of the through hole during die opening is avoided, but because the inclined guide post is only arranged in the sliding hole, the inclined guide post is easy to slide out of the through hole through thrust after sliding into the through hole, the elastic force of the spring can be enhanced for preventing the inclined guide post from sliding out of the through hole, the inclined guide post is difficult to slide out, but the inclined guide post is difficult to push the sliding block to slide into the through hole, the inclined guide post of the core pulling mechanism is difficult to be fast clamped into the through hole, and the inclined guide post cannot stably drive the sliding block to move.

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.

In the sliding block mechanism of the multicolor rotary die, the end face of one end, far away from the hinge point, of the limiting part is provided with a guide surface which is inclined downwards, and the inclination direction of the guide surface is the same as that of the inclined guide pillar.

Through being provided with the guide surface, when oblique guide pillar pushes away spacing portion, the guide surface can increase the area of being under force of oblique guide pillar and spacing portion for oblique guide pillar can be more quick push away spacing portion, further promoted the convenience that slider mechanism used.

In the sliding block mechanism of the multicolor rotary die, the limiting part is positioned in the middle of the strip-shaped through hole, one end of the limiting spring is propped against the cavity wall of the mounting cavity, the other end of the limiting spring is propped against the limiting part, and the limiting spring is arranged along the width direction of the strip-shaped through hole.

Because the direction of spacing spring sets up for spacing spring is more convenient pushes into the bar through-hole with spacing portion in, makes the reset of spacing portion more convenient, and also can make oblique guide pillar promote in place, is difficult for the one end roll-off from the bar through-hole under spacing spring's elasticity effect, has promoted slider mechanism's stability.

In the sliding block mechanism of the multicolor rotary die, the side wall of one side, far away from the hinge point, of the oblique guide post is provided with a limiting surface in a plane shape, the end face, close to one end of the hinge point, of the limiting portion is attached to the limiting surface, and the oblique guide post can vertically slide along the limiting surface.
