The negative pressure molding device is used for molding concave and convex grooves on the outer wall of the plastic shower pipe, and can be used for continuously producing the plastic shower pipe which is provided with the concave and convex grooves on a double-layer wall or an outer layer pipe wall and has the function of resisting dead fold; the negative pressure molding device can be used for molding in an on-line way, avoids heating once again, saves energy and reduces consumption; and the negative pressure molding device takes the atmosphere as a molding medium so as to be environment-friendly.
Description
Technical field
The utility model relates to a kind of plastics bath tube vacuum forming device, through negative pressure of vacuum the macromolecular material of fusion is adsorbed the moulding production that realizes the concavo-convex groove of plastics bath tube.
Background technology
It is solid wall, level and smooth outer wall that existing equipment is produced the plastics bath tube, is prone to slidingly, and bending is prone to dead folding, can not produce the plastics bath tube that Overmolded double wall, outer wall have concavo-convex groove continuously.
Summary of the invention
The purpose of the utility model provides a kind of plastics bath tube vacuum forming device, and Overmolded double wall is produced in realization continuously, outer wall has concavo-convex groove, has anti-dead production of rolling over the plastics bath tube of effect.
The purpose of the utility model realizes as follows: this device comprises internal orifice mould, core, collar extension mould; The internal orifice mould be preceding for the short column body, after the structure that cone-shaped inner hole is arranged of block plate is arranged; The short column body portion of internal orifice mould is with core, and the outside of core is added with electric heater, and the front portion retaining of internal orifice mould has the collar extension mould; Form the runner gap before the short column body of the cone-shaped inner hole of collar extension mould and internal orifice mould between the end toper excircle, the charging aperture that communicates with the runner gap is arranged on the core; The rear portion butt joint vacuum chamber cover of internal orifice mould; The vacuum chamber cover is useful on the endoporus that inserts inner tube; The cone-shaped inner hole center of circle of vacuum chamber cover endoporus and internal orifice mould is on same straight line, and vacuum chamber cover rear end is provided with the vacuum chamber bonnet, and the vacuum chamber bonnet is used for the sealing between inner tube outer wall and the vacuum chamber cover endoporus; Vacuum chamber cover sidewall has the aspirating hole that communicates with endoporus, and this aspirating hole is connected with vavuum pump through pipeline.
Be lined with heat insulation blob of viscose between the joint face of internal orifice mould and vacuum chamber cover, reduce the conduction of heat to vacuum chamber cover direction.
The utility model is to take that macromolecular material is carried out heating and melting to extrude; Form the column type parison of a closed state through shaped device; Utilize negative pressure of vacuum that the macromolecular material of fusion is pushed, be embodied as the production of the concavo-convex groove of plastic bath tube outer wall.At first be heated to molten condition to macromolecular material through electric heater; Extrude the parison that forms sealing by the runner gap; Insert the inner tube that is tied with strengthening rib strip from vacuum chamber cover rear end; The parison of molten condition is coated on inner tube and the strengthening rib strip, through the absorption formation of vavuum pump the outer wall with concavo-convex groove consistent with the reinforcement external form.Can adjust the size of vacuum, make it to arrive the required vacuum forming needs of goods.
The utility model is through extruding high molecule plastic raw material heating and melting; The moulding that utilizes negative pressure that the macromolecular material of fusion is pushed the concavo-convex groove of realizing plastics bath tube outer wall can be produced the plastics bath tube that double wall, outer wall have concavo-convex groove, anti-dead folding effect continuously; Online moulding is avoided heating once more, and is energy-saving and cost-reducing; Atmosphere is a shaping medium, environmental protection.
