Two-color injection machine with rotating shaft and turntable function

This creation is about a two-color injection machine with a rotating shaft and a turntable function, especially a two-color injection machine structure that can quickly and accurately position without hindering the rotation of the rotating shaft and the rotary table, thereby utilizing the set on the rotating shaft. The shaft sleeve corresponds to the first bearing design set in the turntable, and the first creative application is to achieve the effects of reducing the mechanism wear, reducing the production cost and assembling the aging effect.

According to the two-color injection molding, it mainly refers to the two-color or material plastic, which produces the appearance of two-color or double-material effects; and the two-color injection molding machine has two molds, mainly using the mold of the mold. The movable feeding unit is respectively connected to the two feeding units, and then the male mold of the mold can be respectively fixed on the opposite two surfaces of the template which can be rotated 180 degrees, so that the male mold and the female mold are joined to perform one shot and then open the mold. Then, the template is rotated by 180 degrees to change the position of the male mold, and the male mold and the female mold are clamped again, and the secondary injection is performed, and after the mold is opened, the mold is released, and the two-color or double-material can be obtained. However, this two-color molding machine divides the reversible template into a rotary shaft or a rotary disc design because of the basic composition and molding type.

In general, the rotary two-color injection molding machine adjusts the position of the two sets of molds by using the motor to drive the turntable through the transmission gear, and matches the positioning tips and positioning on the mold. The slot design is used for positioning. However, the positioning method may forcibly insert the set position for a long time due to the positioning of the positioning tip and the positioning slot, thereby causing the positioning tip wear or the expansion of the positioning slot, resulting in inaccurate positioning.

The US Patent No. 8,806,507 horizontal injection machine comprises: a rotating plate, which comprises a rotating shaft, which expands in a horizontal direction, and can mount a plurality of molds; and a fixed base, which comprises a rotation supporting a rotating shaft of the cantilever The disk bearing method and the rotary driving device of the rotating disk are characterized in that the rotating disk forms a shape of a magnetic disk and the rotating fixed base is positioned, and the base is provided with a power source for positioning the rotating disk backward, and by rotating the disk The inner spring member acts as a buffer. And the positioning effect of this type can not be accurate.

Then, the rotary shaft type two-color injection molding machine rotates the gear that is sleeved on the outside of the rotating shaft by the rack to rotate the mold fixed on the rotating shaft, and the positioning method is the traveling distance of the number of teeth of the corresponding gear of the rack. Positioning, however, has a backlash problem due to the tooth and tooth drive, thus resulting in a disadvantage of inaccurate positioning.

However, because of the lack of the above-mentioned shaft type or rotary type, the industry has developed and integrated the advantages of the two types, and a rotary type injection molding machine for rotating shafts, such as the announcement No. 337467, is available for detachable shafts. The method comprises: a body comprising a base wall, the base wall having a mounting hole; a shaft tube unit comprising a turntable frame rotatably mounted on the mounting hole, a rotatably mounted on a rotating shaft tube in one of the first axles of the turntable tube, and a rotating shaft driving rod reciprocably movable in a working direction and continuously inserted in a second shaft of one of the rotating shaft tubes The rotating shaft can be coupled with the rotating driving rod; a turntable, including a linked installation a turntable on the turntable tube; a turntable drive mechanism mounted on the body and driving the turntable to rotate by an angle; and a rotary shaft drive mechanism mounted on the body and capable of driving the rotary drive rod to reciprocate along the working direction Move and rotate at an angle. In the above-mentioned structure, the rotary cylinder of the rotary shaft drive mechanism in the rotation axis uses the gear teeth to rotate the rotary shaft, and also has the problem of backlash between the teeth, and the rotating shaft and the turntable are matched with the bearing by the rotating shaft tube and the rotating frame tube to achieve relative rotation. The swirling relationship, but in this way its structure is complex, with a waste of cost and a lack of construction time.

In the light of this, the creators have been able to provide a two-color injection machine with a rotating shaft and a turntable function in order to achieve better performance based on the rich design and development experience and practical production experience of the relevant industry for many years.
