Abstract
Provided is a negative pressure forming device for plastic shower pipe. According to the invention, an inner mouth die has a short column at the front, a bearing disc at the back and a taper inner bore; a mandrel is sleeved on the short column of the inner mouth die; an electric heater is arranged at the exterior side of the mandrel; an outer mouth die is arranged to block the front of the inner mouth die; a runner gap is formed between the taper inner bore of the outer mouth die and a taper outer periphery at the front of the short column of the inner mouth die; the mandrel is provided with a feed inlet communicating with the runner gap; the back of the inner mouth die is butted with a vacuum chamber sleeve which is provided with bores for insertion of inner pipes; a vacuum chamber back cover is arranged at the back of the vacuum chamber sleeve; the bores in the vacuum chamber sleeve are connected with a vacuum pump. The forming device provided in the invention can be used for formation of accidented grooves of outer walls of plastic shower pipes and continuous production of plastic shower pipes with jacketed walls or external walls which have accidented grooves and resistance to dead fold; on-line forming is realized, thereby avoiding reheaing, saving energy and reducing consumption; atmosphere is used as the medium for formation in the invention, thereby realizing environmental protection.
Description
Technical field
The present invention relates to a kind of plastics bath tube vacuum forming device, the macromolecular material of fusion is adsorbed to realize the moulding production of the concavo-convex groove of plastics bath tube by negative pressure of vacuum.
Background technology
It is solid wall, level and smooth outer wall that existing equipment is produced the plastics bath tube, and easily sliding, 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 this invention is to provide a kind of plastics bath tube vacuum forming device, 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 objective of the invention is to realize 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, the outside of core is added with electric heater, 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 layer pipe, the cone-shaped inner hole center of circle of vacuum chamber cover endoporus and internal orifice mould is on same straight line, vacuum chamber cover rear end arranges the vacuum chamber bonnet, the vacuum chamber bonnet is used for the sealing between inner layer pipe 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 by pipeline.
Be lined with heat insulation blob of viscose between the joint face of internal orifice mould and vacuum chamber cover, reduce heat to the conduction of vacuum chamber cover direction.
The present invention takes that macromolecular material is carried out heating and melting to extrude, form the column type parison of a closed state by 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 by electric heater macromolecular material is heated to molten condition, extruded the parison that forms sealing by the runner gap, insert the inner layer pipe that is tied with strengthening rib strip from vacuum chamber cover rear end, the parison of molten condition is coated on inner layer pipe and the strengthening rib strip, by 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 present invention is by extruding high molecule plastic raw material heating and melting, utilize negative pressure to the moulding that the macromolecular material of fusion pushes to realize the concavo-convex groove of plastics bath tube outer wall, can produce the plastics bath tube that double wall, outer wall have concavo-convex groove, anti-dead folding effect continuously; Online moulding is avoided heating again, and is energy-saving and cost-reducing; Atmosphere is shaping medium, environmental protection.
