The utility model aims at providing a movable core mounting device. The anti-falling device is simple in structure and low in manufacturing cost, and on the basis of applying the technical scheme for fixing the movable core, the possibility of losing the movable core can also be reduced.
Description
Technical field
The utility model relates to mold cores technical field, relates in particular to a kind of fixing moving core anti-drop device of ripple pearl screw that adopts.
Background technology
Ripple pearl screw, promotes the motion of spheroid by the spring of certain pressure, make latch fitting trouble-free operation.Ripple pearl screw inside offers the cavity of openings at one side, in cavity, be provided with spring, opening part at cavity is provided with spheroid, opening is slightly less than the diameter of spheroid, make the spheroid cavity that cannot fly out under spring force effect, ripple pearl screw is usually used as pressure and the accurate element of location can be provided.
Mold cores is the mould term of manufacturing industry, and the part that forms product space is called forming part, and the mould parts of shaped article inner surface is called core, claims again submodule or rear mold.From product mold in appearance, the part of projection is core, and recessed part is die cavity, and core and die cavity are to occur in pairs, the die cavity of mould and core matched moulds, and the space of its formation is this mould product shape.
Under the scrutinizing and verify of inventor, find that prior art has following defect:
Mold cores often coordinates and inlays use with moving core, existing moving core is often positioned in the standing groove of offering in main core, and in standing groove, not for fixing the device of moving core, moving core easily comes off and even loses, causing into product cost increases, and reduces production efficiency.
Utility model content
Goal of the invention of the present utility model is to provide a kind of moving core erecting device, and the utility model is simple in structure, and cost of manufacture is low, and the technical scheme that application the utility model provides, on the basis of fixing moving core, has also reduced the probability that moving core is lost.
For addressing the above problem, the utility model is realized by the following technical solutions:
A kind of moving core anti-drop device, comprises main core and moving core, and described moving core is movably set in the groove of offering in described main core.
Unique, in described groove, be provided with fixing pin; On described moving core, offer the through hole being used in conjunction with fixing pin; Described moving core fastens by described fixing pin and described main core.
Further, in described moving core, be provided with ripple pearl screw; Spheroid in described ripple pearl screw is arranged on the side of described through hole; On the lateral surface of described fixing pin, offer the cambered surface groove for fastening with described ripple pearl screw.
Further, on described moving core, offer screw thread with the contact-making surface of ripple pearl screw.
Or, further, offer chamfering at the top of described fixing pin.
The utility model is arranged at the fixing pin with cambered surface groove in main core, in moving core, be provided with ripple pearl screw and fasten with it use, under the elastic force effect of ripple pearl screw inner spring, spheroid and the arc groove of ripple pearl screw inside fasten mutually, and moving core is fixed in main core, as fully visible, the utility model is simple in structure, cost of manufacture is low, and the utility model, on the basis of fixing moving core, has also reduced the probability that moving core is lost.
The utility model also also offers screw thread in mounting groove, for being used in conjunction with ripple pearl screw, can be for regulating ripple pearl screw, reach the elasticity that regulates moving core and main core to fasten, improve the flexibility of moving core slip-off preventing, further improved the steadiness that moving core and main core fasten; Top at fixing pin offers chamfering, is convenient to moving core chimeric toward fixing pin, has reduced the damage of fixing pin to the spheroid in ripple pearl screw, has improved service life of the present utility model.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1:
The present embodiment provides a kind of moving core anti-drop device, comprises main core 10 and moving core 20, offers for inlaying the groove 11 of use with moving core 20 in main core 10.
Especially, in groove 11, be provided with fixing pin 30, on the lateral surface of fixing pin 30, offer cambered surface groove 31.On moving core 20, offer through hole 21 and installing hole 22.Through hole 21, for mating installing with fixing pin 30; The direction of installing hole 22 is perpendicular to through hole 21, and facing to cambered surface groove 31.Also comprise ripple pearl screw 40, ripple pearl screw 40 is arranged in installing hole 22; The direction of the spheroid 41 in ripple pearl screw 40 is facing to cambered surface groove 31.
