Plastic bellows forming machine sliding seat running track

Abstract

The invention relates to a plastic bellows forming machine sliding seat operation track, which comprises an operation track and a sliding seat; and the operation track comprises an inner track and an outer track. The inner track and the outer track respectively comprise an inner inclination segment and an outer inclination segment; and a bearing is arranged on the sliding seat. the length of the inner inclination segment and the outer inclination segment is same which is two times of width of the sliding seat, an inclination angle of the inner inclination segment and the outer inclination segment is 30-35 DEG C, the inner inclination segment and the outer inclination segment are mutually parallel and mutually offset, the length of an overlap segment due to mutual offset equals to half length of the inner inclination segment; the width of the sliding seat equals to half length of the inner inclination segment, an angle close to the sliding seat and close to the inner track of each sliding seat is cut to form an interference-prevented corner cut. The plastic bellows forming machine sliding seat operation track has the beneficial effect that the degree of freedom of the sliding seat is powerful restraint, the processing manufacture cost of the plastic bellows forming machine sliding seat is greatly optimized, and operation efficiency of the plastic bellows forming machine sliding seat is increased.

Description

technical field [0001] The invention relates to a production technology of a plastic corrugated pipe, in particular to an innovation in the operation technology of a rail-type pressure water-cooled molding machine mold in a plastic corrugated pipe forming machine. Background technique [0002] Plastic bellows have the following advantages: [0003] High-density polyethylene (HDPE), polypropylene sliding seat PP sliding seat double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It was first successfully developed in Germany in the early 1980s. After decades of development and improvement, it has developed from a single variety to a complete product line. At present, the production process and application technology are very mature. Due to its excellent performance and relatively economical cost, it has been greatly promoted and applied in developed countries such as Europe and the United States. After HDPE and PP double-wa...

AI Technical Summary

Problems solved by technology

The two rails are inclined at the parting part, and the inclination angle is small, and there will be "intersection" at the parting part. The degree of freedom becomes larger, and it is easy to cause the disordered movement of the sliding seat and cause mutual interference faults
