Abstract

The invention discloses a production process of a spherical polycarbon lampshade. The production process is characterized by comprising the following steps: (1) a tube blank is produced by a plastic injection machine; (2) the tube blank is heated through blowing a processing area in an effective blowing range; then, the heated tube blank is put in a plastic injection mold cavity; a mold head of a blow molding machine is positioned by extending in the mold cavity; and the air inflation is performed for forming; and (3) the formed product becomes the spherical polycarbon lampshade through cutting the effective area.

Description

A kind of manufacture craft of spherical poly-carbon lampshade

Technical field

The present invention relates to field of light fittings, especially a kind of manufacture craft of 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.

Summary of the invention

The defect that the present invention exists in order to solve prior art, the three-step approach forming process of adopt first injection moulding pipe, then blowing, then cut, have the matched moulds spelling of the solution blowing of essence to meet line, product design is attractive in appearance, transparency good, manufacturing cost is light, be not easy breakage.

The manufacture craft of a kind of spherical poly-carbon lampshade of the present invention, is characterized in that following three step moulding: one, first use injection machine processing and fabricating pipe 11; Two, pipe 11 heats by the effective range blowing machining area 111 to blowing, then packs the pipe heating 11 into blow mold cavity 10, and then the die head 2 of blow moulding machine stretches into die cavity 10 location, and then inflation is moulding; Three, the product after moulding by becoming spherical poly-carbon lampshade 1 to the cutting of effective coverage.

The manufacture craft of a kind of spherical poly-carbon lampshade of the present invention, by instance interpretation manufacturing process;

Described pipe 11, on pipe 11, there are blowing machining area 111, blowing FX 112, blowing machining area 111 is delimitated by line of demarcation 114 with blowing FX 112, above FX 112, be shaped with step 113, it is fixing spacing with the position of pipe 11 that step 113 acts on die cavity 10.

Described blow mold cavity 10, die cavity 10 is divided into left and right die cavity 10, left and right die cavity 10 is located and is obtained correct centering by guide pillar, shape 101 in die cavity 10 is shapes that product requires spherical poly-carbon lampshade 1, left and right die cavity 10 is merged formation blow mold, above the pipe 11 of die cavity 10 coordinates the step 113 in districts, be shaped with taper seat 102, taper seat 102 and die head 2 inclined-plane 25 close fit.

Described die head 2, die head 2 connects firmly blow moulding machine, and die head 2 can form scalable workpiece by cylinder or guiding, and during blowing work, die head 2 moves and correctly locates to die cavity 10, the inclined-plane 25 of die head 2 and taper seat 102 close fit of die cavity 10;

Further, by being shaped with, die shank 24, inclined-plane 25, pipe 11 coordinates districts 23, blows muscle 22 die head 2, gas circuit 21 forms.

A kind of manufacture craft of spherical poly-carbon lampshade, first on injection machine, make the pipe 11 of globe holder, pipe 11 is by being heated to blowing machining area 111 temperature that blowing requires, then pipe 11 is put into die cavity 10, then locked mode, then die head 2 deeply coordinates with die cavity 10, the gas circuit 21 of the gas of air pump by die head 2 enters the blowing machining area 111 of pipe 11 endoporus and blows, obtain required converted products shape, after formed product, by cutting and separating, processing FX part becomes the poly-carbon lampshade 1 of finished ball shape.

The specific embodiment:

The invention discloses a kind of manufacture craft of spherical poly-carbon lampshade, as shown in Figure 1,2,3, 4, it is characterized in that following three step moulding: one, first use injection machine processing and fabricating pipe 11; Two, pipe 11 heats by the effective range blowing machining area 111 to blowing, then packs the pipe heating 11 into blow mold cavity 10, and then the die head 2 of blow moulding machine stretches into die cavity 10 location, and then inflation is moulding; Three, the product after moulding by becoming spherical poly-carbon lampshade 1 to the cutting of effective coverage.

The manufacture craft of a kind of globe holder of the present invention, by instance interpretation manufacturing process;

As shown in Figure 1,3, described pipe 11, on pipe 11, there are blowing machining area 111, blowing FX 112, blowing machining area 111 is delimitated by line of demarcation 114 with blowing FX 112, above FX 112, be shaped with step 113, it is fixing spacing with the position of pipe 11 that step 113 acts on die cavity 10.

As shown in Figure 1, described blow mold cavity 10, die cavity 10 is divided into left and right die cavity 10, left and right die cavity 10 is located and is obtained correct centering by guide pillar, shape 101 in die cavity 10 is shapes that product requires spherical poly-carbon lampshade 1, and left and right die cavity 10 is merged formation blow mold, above the pipe 11 of die cavity 10 coordinates the step 113 in districts, be shaped with taper seat 102, taper seat 102 and die head 2 inclined-plane 25 close fit.

As shown in Figure 1, 2, described die head 2, die head 2 connects firmly blow moulding machine, die head 2 can form scalable workpiece by cylinder or guiding, during blowing work, die head 2 moves and correctly locates to die cavity 10, the inclined-plane 25 of die head 2 and taper seat 102 close fit of die cavity 10;

As shown in Figure 1,2,3, 4, a kind of manufacture craft of spherical poly-carbon lampshade, first on injection machine, make the pipe 11 of globe holder, pipe 11 is by being heated to blowing machining area 111 temperature that blowing requires, then pipe 11 is put into die cavity 10, then locked mode, then die head 2 deeply coordinates with die cavity 10, the gas circuit 21 of the gas of air pump by die head 2 enters the blowing machining area 111 of pipe 11 endoporus and blows, obtain required converted products shape, after formed product, by cutting and separating, processing FX part becomes the poly-carbon lampshade 1 of finished ball shape.

Technical staff is appreciated that, can suitably adjust disclosed configuration without departing from the invention, therefore, example is only for the object of example rather than restriction as described above, it will be apparent to those skilled in that and recognize, in not obvious change aforesaid operations situation, can carry out little modification and reach identical object configuration or mounting process, the present invention be restricted by claims.
