Description
Technical field
The utility model relates to a kind of Leave out thread mechanism for the demoulding, belongs 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.
Utility model content
The purpose of this utility model is to provide a kind of Leave out thread mechanism for the demoulding, relies on the ejecting mechanism on die sinking action drives mould, realizes plastic automatic demoulding.
The utility model 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 utility model 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 utility model.
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 utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 be structural representation of the present utility model, the utility model 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 utility model 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 preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
