Abstract
The utility model provides a ball drive mechanism for annotating rotatory screw thread that takes off of plastic product, it relates to injection mold technical field, it contain ball, internal gear, external gear, movable mould part, cover half part, core, ball nut movable mould part be provided with ball, internal gear, external gear, ball and interior gear connection, internal gear and outer gear engagement, external gear and core fixed connection, the last ball nut of installing of ball, the partial top of movable mould is the cover half part. A ball drive mechanism for annotating rotatory screw thread that takes off of plastic product, need not the external screw thread power device that takes off, saved die cost, improved the reliability of production, the utility model has the advantages of simple structure, set up reasonable, the cost of manufacture low.
Description
Technical field
The utility model relates to injection mould technical field, is specifically related to a kind of ball-screw transmission mechanism rotating Leave out thread for injection-molded article.
Background technique
In existing Injection Mould With Automatic Thread Demoulding tool, generally nothing more than having: sprocket driving, rack pinion, Worm Wheel System etc.The disadvantage of above various methodologies is all to provide driving-energy by the external world, as: oil hydraulic motor, motor, oil cylinder, cylinder etc., so bring die cost high, the matching range of mould and injection machine reduces, mould appearance unsightly, in addition, also have except rack pinion, outside Worm Wheel System, the initial position of goods screw thread can not accurately be located, and causes the fit angle of each goods and blow molded bottle to occur differing.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, provides the ball-screw transmission mechanism rotating Leave out thread for injection-molded article that a kind of structure is simple, reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprises ball screw, internal gear, external gear, dynamic model part, cover half part, core, ball nut; Described dynamic model part is provided with ball screw, internal gear, external gear, and ball screw is connected with internal gear, and internal gear engages with external gear, and external gear is fixedly connected with core, and ball screw is provided with ball nut, and the top of dynamic model part is cover half part.
The utility model principle is: the closing mould mechanism of injection machine promotes dynamic model part and the pressing of cover half moieties into close; during die sinking; dynamic model part is separated with cover half part; ball screw moves relative to ball nut; thus drive ball nut and internal gear to rotate; and drive the external gear with screw thread die cavity to rotate by internal gear, because core does not rotate with external gear, force moulding to depart from die cavity.
After adopting said structure, the beneficial effect that the utility model produces is: a kind of ball-screw transmission mechanism rotating Leave out thread for injection-molded article described in the utility model, without the need to external Leave out thread power plant, save die cost, improve the reliability of production, the utility model have structure simple, arrange rationally, the advantage such as fabricating cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1, ball screw; 2, internal gear; 3, external gear; 4, dynamic model part; 5, cover half part; 6, core; 7, ball nut.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1, this embodiment adopts following technological scheme: it comprises ball screw 1, internal gear 2, external gear 3, dynamic model part 4, cover half part 5, core 6, ball nut 7, described dynamic model part 4 are provided with ball screw 1, internal gear 2, external gear 3, ball screw 1 is connected with internal gear 2, internal gear 2 engages with external gear 3, external gear 3 is fixedly connected with core 6, ball screw 1 is provided with ball nut 7, the top of dynamic model part 4 is cover half part 5.
This embodiment principle is: the closing mould mechanism of injection machine promotes dynamic model part 4 and cover half part 5 closely pressing; during die sinking; dynamic model part 4 is separated with cover half part 5; ball screw 1 moves relative to ball nut 7; thus drive ball nut 7 and internal gear 2 to rotate; and drive the external gear 3 with screw thread die cavity to rotate by internal gear 2, because core 6 does not rotate with external gear 3, force moulding to depart from die cavity.
After adopting said structure, the beneficial effect that this embodiment produces for: a kind of described in this embodiment rotates the ball-screw transmission mechanism of Leave out thread for injection-molded article, without the need to external Leave out thread power plant, save die cost, improve the reliability of production, this embodiment have structure simple, arrange rationally, the advantage such as fabricating cost is low.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
