Description

A kind of die head of making spherical poly-carbon lampshade

Technical field

The present invention relates to field of light fittings, especially a kind of die head of making spherical poly-carbon lampshade.

Background technology

Globe holder is of many uses in field of light fittings, and it can be applicable to desk lamp, lamp affixed to the ceiling, pendent lamp, garden lamp, street lamp.

Known globe holder is made by glass, and glass is after heating, and by manual blowing moulding, this processes difficulty is large, the more difficult moulding of larger lampshade, manufacturing cost is higher, because glass belongs to breakables, in manufacturing process, scrappage is very large, user in use, also as easy as rolling off a log breakage.

To sum up, technical staff is in order to change prior art processing mode, attempt the manufacture craft that adopts poly-carbon plastics to carry out blow molding, to mould for glass, solve the existing defect of glassware, poly-carbon plastics belong to transparent rigid plastics, be not easy fragmentation, have in the industry the laudatory title of " shellproof ", use these plastics can greatly improve the yield rate of product, and low cost of manufacture, user is in use also not easy breakage.But in plastics ball blowing process, the spelling of matched moulds meets line retraining the good looking appearance of lampshade, it treats that those of skill in the art further study.

A three-step approach forming process that adopt first injection moulding pipe, then blow, then cuts, has the matched moulds spelling of the solution blowing of essence to meet line, and product design is attractive in appearance, transparency good, manufacturing cost is light, be not easy breakage.

Summary of the invention

The present invention, for solving the described defect of background technology, for realizing three-step approach moulding process, provides a kind of die head that can blow the poly-carbon lampshade of ball-type, can meet technological process for blowing requirement, realize blowing product and meet line, uniqueness attractive in appearance without spelling, manufacturing cost is light, is not easy the advantages such as damaged.

A kind of die head of making spherical poly-carbon lampshade of the present invention, by die shank, inclined-plane, pipe coordinate district, blow muscle, centre bore forms; It is characterized in that die shank is fixed on the blowing head of blow moulding machine, blowing head is provided with telescopic mechanism, when blowing work, pipe packs die cavity into after heating, then blowing head moves down, the mould taper surface close fit of the inclined-plane of die head and spherical poly-carbon lampshade, the pipe of die head coordinates district and pipe close fit, blow muscle and be placed in pipe endoporus middle part, gas circuit is constantly inflated pipe by die head centre bore, the pressure that pipe is bullied expands outwardly to the shape in die cavity, realizes the making to spherical poly-carbon lampshade.

A kind of die head of making spherical poly-carbon lampshade of the present invention, by instance interpretation manufacturing process;

Described die shank, is characterized in that die shank lower bottom part has O type groove, mounting O-shaped rings on O type groove, and die shank is placed in the connecting hole of blowing head by the radially screw locking on blowing head.

Further, die head can form scalable workpiece by cylinder or guiding, and when blowing work, die head moves and correctly locates to die cavity.

Described inclined-plane, is characterized in that inclined-plane is placed in pipe and coordinates district top, and inclined-plane equates with the technical size of the taper seat of die cavity, in the time that blowing is worked, and after die head moves down, the taper seat close fit of inclined-plane and die cavity.

Described pipe coordinates district, it is characterized in that pipe coordinates district to be placed in the below of blow needle upper inclined surface, and pipe coordinates district and pipe FX internal diameter close fit.

The described muscle that blows, blows muscle and is positioned at die head bottom, when processing work, blows muscle and be placed in the machining area middle part of pipe, and the position that acts on air blowing is selected, and the length of blowing muscle exists proportionate relationship with the diameter in kind of processing.

Described centre bore, centre bore acts on gas circuit to be used to lead to, and when blowing work, gas circuit is blown to machined object by centre bore.

A kind of die head of making spherical poly-carbon lampshade, act on the air blowing connector to the poly-carbon lampshade of three-step approach ball-type, do not have the art of this patent just cannot realize three-step approach processing technology, the poly-carbon lampshade of ball-type of blowing by the art of this patent, spheroid contoured surface gloss, uses poly-carbon resin and glass marble contrast, has manufacturing cost light, scrappage is few, not the advantage such as cracky.
