Description

A kind of Leave out thread mechanism for the demoulding
Technical field
The present invention relates to a kind of Leave out thread mechanism for the demoulding, belong to mould emptier component technology field.
Background technology
After action of injection terminates, plastic is cooling and shaping in mould, due to volume contraction, produces package power, when it releases from mould, just must overcome the frictional force produced because of package power to core.Therefore be necessary to provide a kind of motor-driven mould emptier that safety and nondestructive from mould badly is released by the plastic products after cooling curing and running gate system.
Summary of the invention
The object of this invention is to provide a kind of Leave out thread mechanism for the demoulding, rely on the ejecting mechanism on die sinking action drives mould, realize plastic automatic demoulding.
The present invention adopts following technical scheme: a kind of Leave out thread mechanism for the demoulding, it is characterized in that, comprise fixed clamping plate, moving platen, tooth bar guide pillar, gear shaft, described moving platen inside is provided with two vestibules, cylindrical gear shaft I, cylindrical gear shaft II is respectively arranged with in described vestibule, described cylindrical gear shaft I is provided with roller gear I, bevel gear II, described cylindrical gear shaft II is provided with roller gear II, thread core; The left end of described gear shaft is provided with bevel gear I, and the right-hand member of described gear shaft is provided with the pinion matched with the tooth bar of described tooth bar guide pillar.
Preferably, bevel gear I and bevel gear II is connected with a joggle, for by the power transmission of gear shaft to cylindrical gear shaft I.
Preferably, roller gear I and roller gear II is connected with a joggle, for by the power transmission of cylindrical gear shaft I to cylindrical gear shaft II.
Preferably, cylindrical gear shaft I is also provided with screw thread sprue puller, prevents cylindrical gear shaft I from the changing of the relative positions and longitudinal joint gap enlargement occurring.
Preferably, one end of tooth bar guide pillar is fixedly installed on fixed clamping plate.
Preferably, the pinion of tooth bar guide pillar and gear shaft right-hand member is connected with a joggle.
The beneficial effect that the present invention reaches: (1) cylindrical gear shaft I arranges screw thread sprue puller, can prevent cylindrical gear shaft I from the changing of the relative positions and longitudinal joint gap enlargement occurring; (2), during die sinking, plastic can well be stayed on moving platen; (3) thread core automatic demoulding can be realized by rack-and-pinion and gear drive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication marked in figure: 1-bevel gear I, 2-bevel gear II, 3-roller gear I, 4-roller gear II, 5-thread core, 6-fixed clamping plate, 7-moving platen, 8-screw thread sprue puller, 9-tooth bar guide pillar, 10-gear shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1 be structural representation of the present invention, the present invention proposes a kind of Leave out thread mechanism for the demoulding, comprise fixed clamping plate 6, moving platen 7, tooth bar guide pillar 9, gear shaft 10, described moving platen 7 inside is provided with two vestibules, cylindrical gear shaft I, cylindrical gear shaft II is respectively arranged with in described vestibule, described cylindrical gear shaft I is provided with roller gear I3, bevel gear II2, described cylindrical gear shaft II is provided with roller gear II4, thread core 4; The left end of described gear shaft 10 is provided with bevel gear I1, and the right-hand member of described gear shaft 10 is provided with the pinion matched with the tooth bar of described tooth bar guide pillar 9.
Bevel gear I1 and bevel gear II2 is connected with a joggle, for by the power transmission of gear shaft 10 to cylindrical gear shaft I; Roller gear I3 and roller gear II4 is connected with a joggle, for by the power transmission of cylindrical gear shaft I to cylindrical gear shaft II; Cylindrical gear shaft I is also provided with screw thread sprue puller 8, prevents cylindrical gear shaft I from the changing of the relative positions and longitudinal joint gap enlargement occurring; One end of tooth bar guide pillar 9 is fixedly installed on fixed clamping plate 6; Tooth bar guide pillar 9 is connected with a joggle with the pinion of gear shaft 10 right-hand member.
Operation principle: the present invention utilizes rectilinear motion during die sinking, by the rack pinion of the pinion of tooth bar guide pillar and gear shaft right-hand member by power transmission to gear shaft, then by Bevel Gear Transmission by power transmission to cylindrical gear shaft I, then by column gear transmission by power transmission to cylindrical gear shaft II, thus make thread core do gyration and depart from plastic.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
