Abstract
The invention discloses a core mechanism comprising a fixed die, a moving die, a threaded core, a ribbed core and a push bar, wherein the threaded core and the ribbed core are fastened in a non-fixed connection way; the ribbed core 4 is arranged in the moving die; the push bar arranged in a hole arranged on the moving die and the ribbed core are fastened; the fixed die is arranged outside the threaded core; and the fixed die and the moving die are fastened in a non-fixed connection way. According to the invention, after the die opening of the core mechanism, the threaded core is screwed out from the ribbed core to ensure that the acting force of the push bar to a movable insert is reduced and a casting is easier to push out; the core mechanism is simple in structure and small in volume to ensure that the use occasion is not restrained by space; moreover, the input cost is low to ensure that the work efficiency is higher.
Description
Technical field
The present invention relates to a kind of core mechanism.
Background technology
Society is for adapting to modern step now, and a lot of factories have all adopted streamline production, make large-scale batch production become possibility; Because in the permanent mold casting process, the core of common metal system must in time be extracted core behind metal freezing; If whose surfaces is the inclined plane, core just is difficult to pull out, and under the motor-driven situation of loosing core of some streamline productions; If mould structure is complicated, the high efficiency mass production just is difficult to realize.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, a kind of core mechanism is provided, this core mechanism is simple in structure, easy to operate, and demoulding efficiency is high.
Technical scheme: in order to realize above purpose; A kind of core of the present invention mechanism, it comprises: cover half, dynamic model, thread core, core with ribbing and push rod, described thread core and core with ribbing are fastening through the on-fixed ways of connecting; Described core with ribbing 4 is located in the dynamic model; Push rod that is provided with in the hole that described dynamic model is provided with and core with ribbing are fastening, and the outside of thread core is provided with cover half, and described fixed half and moving half is fastening through the on-fixed ways of connecting.
Be provided with injecting hole between the described fixed half and moving half.
Such die cavity between described thread core and the dynamic model.
Described thread core and core with ribbing are fastening through the mode that is threaded
Beneficial effect: a kind of core provided by the invention mechanism, because of this core mechanism after die sinking, after thread core screwed out from core with ribbing; Reduced the active force of push rod to loose plug, easier foundry goods has been ejected, this mechanism structure is simple; Volume is little; So the occasion of using does not receive the constraint in space, and input cost is little, makes operating efficiency higher.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1, a kind of core of the present invention mechanism, it comprises: cover half 1, dynamic model 2, thread core 3, core with ribbing 4 and push rod 5.
Described thread core 3 is fastening through the on-fixed ways of connecting with core 4 with ribbing; Described core with ribbing 4 is located in the dynamic model 2; The push rod 5 and the core with ribbing 4 that are provided with in the hole that described dynamic model 2 is provided with are fastening; The outside of thread core 3 is provided with cover half 1, and described cover half 1 is fastening through the on-fixed ways of connecting with dynamic model 2.
Be provided with injecting hole 6 between described cover half 1 and the dynamic model 2.
Such die cavity 7 between described thread core 3 and the dynamic model 2.
Described thread core 3 and core 4 with ribbing through the mode that is threaded fastening after; Core 4 with ribbing is located in the dynamic model 2, again by described cover half 1 and dynamic model 2 place respectively thread core 3 and core 4 with ribbing top and bottom and fastening after, liquid metals is poured into a mould to die cavity 7 from being provided with between cover half 1 and the dynamic model 2 in the injecting hole 6; Behind to be cast the finishing; Treat its cooling, with push rod 5 foundry goods, thread core 3 and core with ribbing 4 are released simultaneously again, again core 4 with ribbing is stepped up; Rotate thread core 3 then; Utilize on the core 4 with ribbing foundry goods rib 8 splines of the moulding of protrusion,, with push rod 5 thread core 3 is released from foundry goods at last and got final product then with screwing out the internal thread of the external screw thread on the thread core 3 from core 4 with ribbing.
Because of this core mechanism after die sinking, after thread core screwed out, reduced the active force of push rod to loose plug from core with ribbing; Easier foundry goods is ejected, this mechanism structure is simple, and volume is little; So the occasion of using does not receive the constraint in space, and input cost is little, makes operating efficiency higher.
Above-mentioned embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit is made according to the present invention or modification all should be encompassed within protection scope of the present invention.
