Flaring demolding mechanism for flaring pipe fitting

Abstract

The invention discloses a flaring demolding mechanism for a flaring pipe fitting, which comprises a fixing base, a slide female die, a fixing plate, a water core, a wedge block, a slide male die, 2 to 4 wedge plates, a mounting base, a slide connecting plate, a slide sleeve, 2 to 4 pull rods and 2 to 4 ball bearings, wherein the slide female die and the fixing plate are fixed to two ends of the fixing base; the water core is fixed on the fixing plate; the wedge block and the mounting base are slidably arranged on the water core; the wedge plates fixedly connected with the mounting base are slidably connected to the wedge block; the slide male die comprises a slide insert fixed to the front end of the water core, small valve blocks slidably connected to the left part of the wedge block and large valve blocks slidably connected to the left part of the same wedge plate; the slide sleeve is slidably sleeved on the fixing base; the slide connecting plate is fixed to the right end of the slide sleeve; the pull rods pass through the mounting base and the fixing plate in a mode of central symmetry, and both ends of the pull rods are fixed on the wedge block and the slide connecting plate respectively; the ball bearing is arranged in the mounting base; and when used, the slide connecting plate is connected with a power output piece of an oil cylinder.

Description

technical field [0001] The invention relates to a part of a manufacturing mold of a plastic flaring pipe fitting, in particular to a flaring demoulding mechanism of a manufacturing mold of a small diameter flaring pipe fitting. Background technique [0002] Plastic pipe fittings and plastic pipes are commonly used in water supply and drainage systems, and plastic pipes of the same or different diameters are connected together through plastic pipe fittings. Pipe fittings generally include straight through, elbow, tee, cross and so on. When the pipes are connected together by pipe fittings, the usual structure is: each port of the pipe fittings is made into a flared shape (that is, a circumferentially arranged circular groove is formed on the inner wall of the pipe opening) , install a sealing ring in the flaring, and then insert one end of the pipe into a corresponding port of the corresponding pipe, and elastically expand the sealing ring between the pipe and the fitting, s...

AI Technical Summary

Problems solved by technology

Although the production efficiency has been improved, because the wall of one of the two ports of the pipe is still uneven in thickness, the pressure that the seal can withstand is still not improved when the pipe is connected.

In addition, when the flaring core demoulding mechanism is demolding, the large slider and the small slider have to swing to separate from the flared part of the product. In the long run, the fixed position of the large slider and the small slider is prone to loosening. The matching connection of the movable groove B and the movable groove A is also prone to wear and tear, which causes the mechanism to fail easily and have a short service life
