Abstract
The utility model discloses a sleeving ball groove type mold sinking core pulling mechanism of an injection mold. The sleeving ball groove type mold sinking core pulling mechanism is characterized in that an upper mold is provided with an outer sleeve and an inner sleeve, wherein the outer sleeve is arranged on the inner sleeve in a sleeving manner, a return spring is arranged in the outer sleeve, the upper end of the return spring pushes against the top inner wall of the outer sleeve, the lower end of the return spring pushes against the top outer wall of the inner sleeve, the side wall of the inner sleeve is provided with a plurality of through holes formed in the same height, a steel ball is installed in each through hole, the lower inner wall of the outer sleeve is provided with a clamping groove corresponding to each steel ball, an insertion rod is inserted on the inner sleeve, the insertion rod is provided with an insertion rod end and an insertion rod neck part, the diameter of the insertion rod neck part is smaller than that of the insertion rod end, and in a mold assembling state, the steel balls are locally arranged on the insertion rod neck part, and the steel balls clamp the insertion rod end. According to the sleeve ball-groove mold sinking core pulling mechanism, the return spring is arranged in the outer sleeve, the upper end of the return spring pushes against the top inner wall of the outer sleeve, the lower end of the return spring pushes against the top outer wall of the inner sleeve, return force provided by the return spring is more stable and more powerful than that of a rubber band; moreover, the return spring is arranged in the outer sleeve, so that the structure is relatively firm.
Description
Technical field
The utility model relates to the sleeve ball slot type die sinking core-pulling mechanism of injection mold.
Background technology
The sleeve ball slot type die sinking core-pulling mechanism of traditional injection moulding mould, comprises upper die and lower die, and wherein patrix relies on rubber band to pull out reset die sinking.But the pulling force of rubber band is inadequate, and the restoring force providing is unstable, and structure is also firm not.
Summary of the invention
In view of the deficiency that background technology exists, technical problem to be solved in the utility model is to provide the sleeve ball slot type die sinking core-pulling mechanism of the injection mold that a kind of structure is more firm, the restoring force of resetting-mechanism is more stable more greatly.
The utility model takes following technical scheme to complete: the sleeve ball slot type die sinking core-pulling mechanism of injection mold, comprise upper die and lower die, described patrix is with outer sleeve and inner sleeve, described outer sleeve is enclosed within on inner sleeve, in described outer sleeve, be provided with back-moving spring, back-moving spring upper end withstands in the top inner wall of outer sleeve, the lower end of back-moving spring withstands in the top exterior walls of inner sleeve, on described inner sleeve sidewall, offer multiple through holes in sustained height, in through hole, be mounted with steel ball, the corresponding steel ball of lower inner wall of described outer sleeve offers retaining groove, on described inner sleeve, be plugged with inserted link, inserted link is with inserted link termination and inserted link neck, described inserted link recess diameter is less than the diameter of inserted link termination, under matched moulds state, described steel ball part is in inserted link neck, steel ball blocks inserted link termination, under die opening state, when described steel ball enters in retaining groove, steel ball departs from the screens to inserted link termination, inserted link termination departs from inner sleeve downwards.
In the utility model, in described outer sleeve, be provided with back-moving spring, back-moving spring upper end withstands in the top inner wall of outer sleeve, the lower end of back-moving spring withstands in the top exterior walls of inner sleeve, the restoring force that back-moving spring provides compares that rubber band is more stable, strength is larger, and back-moving spring is in outer sleeve, its structure is more firm.
Accompanying drawing explanation
The structure cross-sectional schematic of the injection mold that Fig. 1 provides for the utility model.
Fig. 2 is the structure cross-sectional schematic of the sleeve ball slot type die sinking core-pulling mechanism of the injection mold in Fig. 1, and what this figure showed is matched moulds state.
Fig. 3 is the structure cross-sectional schematic of the sleeve ball slot type die sinking core-pulling mechanism of the injection mold in Fig. 1, and what this figure showed is the state in die sinking process.
The specific embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, will be further described below each details and the operation principle thereof of embodiment.
As shown in Figure 1, the sleeve ball slot type die sinking core-pulling mechanism of the injection mold that the utility model provides, comprise patrix 1 and counterdie 2, described patrix 1 is with outer sleeve 3 and inner sleeve 4, described outer sleeve 3 is enclosed within on inner sleeve 4, in described outer sleeve 3, be provided with back-moving spring 5, back-moving spring 5 upper ends withstand in the top inner wall of outer sleeve 3, the lower end of back-moving spring 5 withstands in the top exterior walls of inner sleeve 4, on described inner sleeve 4 sidewalls, offer multiple through holes 6 in sustained height, in through hole 6, be mounted with steel ball 7, the corresponding steel ball 7 of lower inner wall of described outer sleeve 3 offers retaining groove 8, on described inner sleeve 4, be plugged with inserted link 9, inserted link 9 is with inserted link termination 10 and inserted link neck 11, described inserted link neck 11 diameters are less than the diameter of inserted link termination 10, under matched moulds state, described steel ball 7 parts are in inserted link neck 11, steel ball 7 blocks inserted link termination 10, under die opening state, described steel ball 7 enter retaining groove 8 when interior steel ball 7 depart from the screens to inserted link termination 10, inserted link termination 10 departs from inner sleeve 4 downwards.
Describe in detail with reference to the accompanying drawings workflow below in detail: as shown in Figure 2, mould is in matched moulds state, and now outer sleeve 3 gos deep into sleeve with inner sleeve 4, and the retaining groove 8 in outer sleeve 3 is in steel ball 7 belows, and inserted link termination 10 is blocked by steel ball 7; As shown in Figure 3, in the process of mould in die sinking, now steel ball 7 enters in retaining groove 8, and steel ball 7 no longer blocks inserted link termination 10; When state that mould completes in die sinking, the termination 10 of now pegging graft departs from inner sleeve 4 completely.The structure that the utility model provides is mainly applicable to need the two ends injection mold of die sinking of loosing core respectively, and in above-mentioned title, not to refer in particular to mould be up-down structure to so-called upper die and lower die, but for describing and set for accompanying drawing.
