The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-2, a kind of no-spill injection molding machine extrusion device, including bottom plate 1, injection mold 2, feed pipe 3, feeding 3 lower end of pipe is welded with injection molding tube 4, and feed pipe 3 is connected to setting with injection molding tube 4, is equipped with injecting hole 5 in injection molding tube 4, on injection molding tube 4 It is welded with fixed plate 6,6 lower end of fixed plate is welded and fixed with bottom plate 1, and threaded rod 7 is equipped in injecting hole 5, and threaded rod 7 runs through feeding The right wall of pipe 3 is simultaneously rotatablely connected with feed pipe 3, and 7 right end of threaded rod is connected with first bevel gear 8 using flat key interference fit, the One bevel gear 8 is engaged with second bevel gear 9, runs through in fixed plate 6 and is equipped with stud 24, and stud 24 is threadedly coupled with injection mold 2, Stud 24 is slidably connected with fixed plate 6, and 24 right end of stud is provided with release unit, consistent with existing general state of the art It is that by plastic heating at hot melt state in feed pipe 3, then hot melting plastic is flowed into injecting hole 5, and is turned in threaded rod 7 Movement is in lower injection mold；

1 upper end of bottom plate is welded with the first column 10, and first sliding groove 11 is offered on bottom plate 1, and sliding connects in first sliding groove 11 The second column 12 is connect, 12 upper end of the second column is welded with mounting plate 13, and 13 lower wall of mounting plate offers second sliding slot 14, and first is vertical Column 10 slides in second sliding slot 14, is welded with the first spring 15 between the first column 10 and the second column 12, on mounting plate 13 Servo motor 17 is installed using bolt, 17 left end of servo motor is connect with release unit, and two of 17 lower end of servo motor are vertical Column guarantees that servo motor 17 has the tendency that moving right with the second column 12 under the action of not by external force, makes second bevel gear 9 engage with the holding of first bevel gear 8.

Release unit includes baffle 23 and push rod 16, and baffle 23 is welded on 24 right end of stud, and push rod 16 is welded on servo electricity The left end of machine 17, push rod 16 is horizontally disposed, several Tapered Columns 18 is provided through on push rod 16, each Tapered Column 18 passes through jointly It is installed with the first synchronous plate 19, each Tapered Column 18 is welded and fixed with the first synchronous plate 19, and each 18 lower end of Tapered Column is welded jointly It is connected to the second synchronous plate 21, second spring 20,20 upper end of second spring and the first synchronous plate are arranged on each Tapered Column 18 19 offset, and lower end and the push rod 16 of second spring 20 offset, and after completing primary injection molding work, pulling downward on handle 22 makes wedge shape Column 18 is disengaged with baffle 23, and can be rotated baffle 23 screws out stud 24 from injection mold 2, while pulling downward on handle 22, Tapered Column 18 does not offset with baffle 23, and sliding makes the second cone to servo motor 17 to the right under the action of the first spring 15 at this time Gear 9 and first bevel gear 8 restore meshing relation.

It is arranged with third spring 25 outside stud 24,25 both ends of third spring offset with baffle 23 and fixed plate 6 respectively, third Spring 25 guarantees that injection mold 2 offsets with injection molding tube 4；Second synchronous plate, 21 lower end is welded with handle 22, and the presence of handle 22 is just The second synchronous plate 21 is pulled downward in staff；Second bevel gear 9 be located at the left end of first bevel gear 8 when servo motor 17 to Two bevel gears can be disengaged from relationship when left movement.

In the utility model, when needing to carry out injection molding work to injection mold 2,5 left end of injecting hole and injection mold 2 should be made Injection hole offset, by stud 24 screw in injection mold 2 in, under the action of third spring 25, injection mold 2 keep and injection molding Pipe 4 offsets；Baffle 23 and the right wall of some Tapered Column 18 offset at this time；

There is hot melting plastic in feed pipe 3,3 lower end of feed pipe is connected to injecting hole 5, and starting servo motor 17 drives the second cone Gear 9 rotates, and then first bevel gear 8 is driven to rotate, and first bevel gear 8 drives threaded rod 7 to rotate, and threaded rod is in injecting hole 5 Interior rotation flows into hot melting plastic in injection mold 2 from injecting hole 5.When injection mold 2 is not filled with, servo motor 17 is still Rotation is kept, makes hot melting plastic continue to be perfused into injection mold 2, after injection mold 2 is filled with, continues to injection mold 2 When middle injection hot melting plastic, injection mold 2 is moved to the left because being filled with, and Tapered Column 18 is driven to be moved to the left, and then is driven and watched Motor 17 is taken to be moved to the left, second bevel gear 9 is moved downward with servo motor 17 is disengaged from it with first bevel gear 8, into And make servo motor 17 that threaded rod 7 can not be driven to rotate, and then make the hot melting plastic in injection molding tube 4 that can not continue to flow out and occur The phenomenon that spilling, is then shut off servo motor 17.

It is worth noting that starting before being molded work, the Tapered Column 18 of baffle 23 and different location is made to offset and can adjust The dynamics that offsets of injection mold 2 and injection molding tube 4 so that when carrying out injection molding work to different injection molds 2, injection molding tube 5 with The injection hole of injection mold 2 closely offsets, but before starting to be molded work, should ensure that two bevel gears keep meshing relation.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
