Description
Technical field
The utility model belongs to injection mold and manufactures field, particularly injection mold screw thread ejecting mechanism.
Background technology
Running gate system coagulates the ejecting mechanism of material, in all kinds of cast gate, except spot pouring mouth and tunnel gate, other forms of cast gate running gate system when the demoulding coagulates material and working of plastics connects together outside disengaging mould, then be isolated by hand, this just causes goods to enter cast gate place and leaves very large weld mark, poor product quality, surface unsightly, when there is screw thread in product, if screw thread is less demanding, then can directly adopt the die joint divided half-and-half, if screw thread requires high, do not allow the parting line that die joint stays, then need to design corresponding screw thread ejecting mechanism.Screw thread ejecting mechanism comprises mould inside power source screw thread ejecting mechanism and mold exterior power source screw thread ejecting mechanism.
Utility model content
The purpose of this utility model is to provide a kind of injection mold screw thread ejecting mechanism for being threaded working of plastics and carrying out the demoulding.
To achieve these goals, the injection mold screw thread ejecting mechanism that the utility model provides, comprise panel, base plate, patrix, counterdie, fixed head, external thread rod and threaded mandrel, described panel and patrix are fixed, described external thread rod is fixed by screws in panel geometric center place, described external thread rod is successively through patrix, counterdie fixed head and base plate, arrange containing female gear ring between described fixed head and external thread rod, the bar portion of described threaded mandrel is connected with fixed head by bearing, the bar portion of described threaded mandrel is fixedly installed driven gear, power gear is provided with between described driven gear and gear ring, described gear ring is also connected with fixed head by bearing, described threaded mandrel top is provided with screw thread and forms injection molding cavity with patrix.
The injection mold screw thread ejecting mechanism of this programme when in use, due to the screw thread of threaded mandrel outside in injection moulding process, injection moulding working of plastics is out made to have internal thread, when the needs demoulding time, to power gear power, make power gear drive gear ring and driven gear to rotate simultaneously, internal thread is provided with in gear ring, ring gear against rotation process makes external thread rod upwards exit gradually, driven gear drives threaded mandrel to rotate simultaneously, threaded mandrel and external thread rod move round about, exit moulding gradually, and the screw thread of moulding is remained intact.
The utility model has the advantage of: the mode exited by screw thread rotation is realized tapped moulding and exits, effectively ensure that the integrity of its internal thread, and by gear driven driven gear and gear ring, external thread rod and threaded mandrel is made to realize, with frequently rotating, preventing the interference of the demoulding.
As preferred scheme, described threaded mandrel by threaded rod in a center of symmetry arrange multiple; As long as manufacture while a matched moulds just can complete multiple like this.
As preferred scheme, described gear ring is copper alloy gear ring, because copper alloy has good mechanical strength, and can prevent corrosion, can extend the service life of gear ring.
As preferred scheme, described lower panels is provided with reinforcement central layer, when can prevent each demoulding by strengthening central layer, and the situation of patrix and the distortion of panel connecting portion.
Accompanying drawing explanation
Fig. 1 is injection mold screw thread ejecting mechanism structural representation.
Reference numeral is enumerated: panel 1, reinforcement central layer 2, patrix 3, counterdie 4, fixed head 5, driven gear 6, gear ring 7, external thread rod 8, power gear 9, base plate 10, bearing 11, threaded mandrel 12.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail below by detailed description of the invention:
Injection mold screw thread ejecting mechanism as shown in Figure 1, comprise panel 1, base plate 10, patrix 3, counterdie 4, fixed head 5, external thread rod 8 and threaded mandrel 12, panel 1 and patrix 3 are fixed, external thread rod 8 is fixed by screws in panel 1 geometric center place, external thread rod 8 is successively through patrix 3, counterdie 4, fixed head 5 and base plate 10, arrange containing female gear ring 7 between fixed head 5 and external thread rod 8, the bar portion of threaded mandrel 12 is connected with fixed head 5 by bearing 11, the bar portion of threaded mandrel 12 is fixedly installed driven gear 6, power gear 9 is provided with between driven gear 6 and gear ring 7, gear ring 7 is also connected with fixed head 5 by bearing 11, threaded mandrel 12 top is provided with screw thread and forms injection molding cavity with patrix 3.
This programme when in use, due to the screw thread of threaded mandrel 12 outside in injection moulding process, injection moulding working of plastics 13 is out made to have internal thread, when the needs demoulding time, to power gear 9 power, make power gear 9 drive gear ring 7 and driven gear 6 to rotate simultaneously, internal thread is provided with in gear ring 7, gear ring 7 rotation process makes external thread rod 8 upwards exit gradually, driven gear drives threaded mandrel to rotate simultaneously, threaded mandrel and external thread rod move round about, exit moulding gradually, and the screw thread of moulding is remained intact.
Threaded mandrel 12 by threaded rod in a center of symmetry arrange multiple; As long as manufacture while a matched moulds just can complete multiple like this.Gear ring 7 is copper alloy gear ring, because copper alloy has good mechanical strength, and can prevent corrosion, can extend the service life of gear ring 7.Be provided with below panel 1 and strengthen central layer 2, when can prevent each demoulding by strengthening central layer 2, the situation of patrix and the distortion of panel connecting portion.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
