Description
Technical field
The utility model relates to a kind of cloud look plastic products list spiro rod plasticizing mechanism, and this mechanism is applicable to that injection-moulding plastic production colour mixture requires cloudlike chromatic pattern or is marblized goods.
Background technology
Be used to make the plastic products of multiple color in the prior art, generally be to adopt clear double-colored technology or colour mixture technology, and conventional colour mixture technology adopts two cover plasticizing systems, need two cover control system and oil piping systems, to the plasticizing head plastics of thawing are mixed, and enter mold cavity with a nozzle, the shortcoming of this sets of plan is the structure more complicated, make trouble, the manufacturing cost height, and the specificity that the goods of cloud look (marbling) are required is not strong.In order to satisfy the goods needs of cloud look (marbling), the ad hoc cloud shape decorative pattern plastic products list spiro rod plasticizing mechanism that counted.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of simple and reasonable, goods cloud outstanding effect cloud shape decorative pattern plastic products list spiro rod plasticizing mechanism is provided.
The technical scheme in the invention for solving the above technical problem is: this cloud shape plastic products list spiro rod plasticizing mechanism, its characteristics are: only use a cover plasticizing apparatus, comprise nozzle, preceding barrel, barrel, screw rod, spreader, heating collar, thermocouple, the preformed motor, thrust bearing and injection seat, barrel is by alignment pin, nut and get rid of mother and be fixed on the injection seat, preceding barrel is fixed on the barrel, nozzle is fixed on the preceding barrel, the barrel outer wall is equipped with heating collar and thermocouple, screw rod is fixed on the power transmission shaft of thrust bearing, power transmission shaft links to each other with the preformed motor, also be provided with spreader in the described barrel, also be provided with spreader in the described barrel, spreader places the barrel front end, and on the barrel, the other end was cone-shaped before an end was fixed on.
Axially be evenly distributed with many charging runners on the spreader described in the utility model, one end of every close preceding barrel of charging runner is provided with inclined hole, inclined hole one end is communicated with the charging runner, and the inclined hole other end is provided with and converges the hole, and it is identical with nozzle endoporus aperture to converge the aperture, hole.
The utility model compared with prior art has the following advantages: at the goods of running into cloud look (marbling) in the injection-moulding plastic production, as the button on the overcoat, toothbrush handles, comb, picture frame and shoehorn etc., specially design cloud colour product list spiro rod plasticizing mechanism, principle is the plastics with different colours, become uneven admixture with spiro rod plasticizing, again through spreader shunting and thawing fully, because injection pressure height, when material by spreader on behind the inclined hole, enter the hole of converging of spreader head, the solution plastics under high pressure fully mix, and mixed plastic is moulding in mold cavity, will become cloud look (marbling) goods after the cooling.If the viscosity of several plastics, color distortion are bigger, goods cloud effect will be more obvious.The utility model compact conformation, processing and easy for installation, control and hydraulic system do not need to carry out particular design.Since need not many retableization system, what manufacturing cost will be low with respect to prior art is many.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, the utility model comprises: nozzle 1, preceding barrel 2, barrel 3, thermocouple 4, spreader 5, heating collar 6, screw rod 7, alignment pin 8, nut 9, get rid of female 10, power transmission shaft 11, injection seat 12, thrust bearing 13 and preformed motor 14.
Barrel 3 is by alignment pin 8, nut 9 and get rid of female 10 and be fixed on the injection seat 12, preceding barrel 2 usefulness hexagon socket cap head screws are fixed on the barrel 3, and barrel 3 Inner Front Ends are provided with spreader 5, and spreader 5 one ends are fixed on the preceding barrel 2, the other end 19 is cone-shaped, helps plastic solution and flows into.Described spreader 5 axially is evenly equipped with many charging runners 18, and an end of every charging runner 18 close preceding barrels 2 is provided with inclined hole 16, and inclined hole 16 1 ends are communicated with charging runner 18, so that allow plastics by entering spreader 5 front ends.Inclined hole 16 other ends are provided with and converge hole 17, and it is identical with nozzle 1 endoporus aperture to converge 17 apertures, hole.Nozzle 1 is fixed on the preceding barrel 2.Barrel 3 outer walls are equipped with heating collar 6 and thermocouple 4, can regulate the temperature of plastic melt.
Screw rod 7 is fixed on the power transmission shaft 11 of thrust bearing 13, and power transmission shaft 11 directly links to each other with preformed motor 14, just can drive the screw rod rotation when preformed motor 14 rotates, and plays plastication.Injection cylinder (showing not have with this patent and contact directly on the figure, general with common injection machine) is housed on thrust bearing 13, when injection cylinder moves, can lead-screw 7, thus screw rod 7 plays the plunger effect, reaches the pusher effect.
When compound enters barrel 3 the insides from the feed opening 15 on the injection seat 12, because the rotation of screw rod 7, thereby make plastics become half solution under the shearing double action of heating collar 6 heating and screw rod 7, under the effect of injection cylinder, spreader 5 is gone in half solution materials flow, on spreader 5, because under the effect of heating collar 6, half solution material melts gradually and is solution, when solution by spreader 5, before entering, fully mix when barrel 2 and nozzle 1, enter mould molding again.
