Description

A forming mechanism for a turbocharged special-shaped tube with an arc-shaped track slider

technical field

The invention relates to the field of mold equipment, in particular to a molding mechanism for a turbocharged special-shaped pipe with an arc-shaped track slider.

Background technique

Core pulling is used to deal with the position on the parting surface of the product that cannot be demolded. It belongs to the "barb treatment system" and is a structure of the mold. Definition of core pulling: the mechanism that ensures the smooth demoulding of the product, also called the slider. For example, there is a hole on the side of a plastic part. After the mold is opened, if the core of the hole is not removed, the product cannot be ejected.

At this time, the mold structure must adopt the structure of the slider, and the core of the hole is made movable, and the inclined guide column is used to cooperate with the fixed mold, and the slider moves with the opening or closing of the mold. This movement is called core pulling.

At present, the known pipe bending mold mechanism is limited to parallel core pulling, slightly angled core pulling with short stroke, and core pulling with heterogeneous bend stroke trajectory, but when the angle of the bend pipe is large, the core pull stroke is too long , when the travel trajectory is heterogeneous, the molding of the product cannot be completed.

Detailed ways

As shown in Figures 1 to 4, a molding mechanism for a turbocharged special-shaped pipe with an arc-shaped track slider includes a first molding core 1 arranged in the mold cavity, and the first molding core 1 is connected to the second A linkage extraction mechanism, the first linkage extraction mechanism includes a small slider 2, a large slider 3, a pull rod 4, an oil cylinder 5 and a directional guide rail bead 6, the end of the first forming core 1 is installed in the small slider 2, the small slider The slider 2 is installed on the big slider 3, the big slider 3 is connected with the oil cylinder 5 through the pull rod 4, and the end of the big slider 3 is slidingly engaged with the directional guide rail bead 6.

Wherein, the small slider 2 is fixedly connected with the big slider 3, and the bottom of the big slider 3 is hinged with the pull rod 4. The end of the pull rod 4 is hinged with the cylinder rod of the oil cylinder 5, and the directional guide rail bead 6 is arc-shaped.

Further, a second molding core 7 corresponding to the first molding core 1 is also provided in the mold cavity, and the second molding core 7 is connected to a second linkage extraction mechanism, which includes an arc-shaped rack 8, One side of the arc-shaped rack 8 meshes with the circular gear 9 , the bottom of the circular gear 9 meshes with the straight rack 10 , and the end of the straight rack 10 is connected to the oil cylinder 11 . The middle part of the circular ring gear 9 and the arc rack 8 is pierced with a rotating shaft, the rotating shaft is installed on the mould, the end of the second molding core 7 is hinged with the edge of the arc rack 8, and the The section is fan-shaped.

When the product 12 is formed, the first molding core 1 needs to be pulled out. During the mold opening process, the small slider 2 moves to the designated position due to the guiding effect of the locking block of the front mold. After the mold is fully opened, the oil cylinder 5 moves. The pull rod 4 connected to the oil cylinder 5 drives the large slider 3 to move, and the large slider 3 moves to the end position with the guidance of the directional guide rail bead 6, so far, the first forming core 1 is completely drawn out of the product;

When the second molding core 7 needs to be drawn out, start the oil cylinder 11, and the oil cylinder 11 will drive the straight rack 10 to move upward, the straight rack 10 will drive the engaged circular gear 9 to rotate, and the circular gear 9 will drive the arc rack 8 rotates, and the arc-shaped rack 8 drives the forming core 7 to be slowly drawn out along a specific angle.
