Abstract
The production method of lock body includes the following steps: according to the pattern and form making compression casting die, using core-loosening method to design lock body, pre-retaining cavity of lock core, pouring molten alloy material into die, compression casting by utilizing thermal chamber compression casting machine to one-step form lock body and internal cavity, then assembling lock core, lock ring, spring and key ring, finally making surface treatment.
Description
1. technical field
The present invention relates to a kind of manufacture method of lock body.
1. background technology
Up to now, the barred body cutting type is adopted in the lock body processing of copper used in everyday, iron lock always.Promptly make the strip longitudinal profile earlier, again section bar is cut the formation lock body piecemeal, again lock body is carried out the boring of various directions and size, to make the lock core die cavity.Refill and join lock core, lock ring.The shortcoming of this manufacture method is that lock body can not change along y direction, so surface of lock body can not be made space pattern, makes the moulding of lock body appearance owe attractive in appearance; In addition, the lock core die cavity by the lock body moulding after boring one by one, processing location is difficult, causes the processing dimension between individuality, the difference of location easily, influences quality; Lock core die cavity manufacturing procedure is tens roads nearly, under the efficient.At last, the copper surface of lock body can't be electroplated, iron lock body, and the surface generally also can only be painted.
3. summary of the invention
The manufacture method that the present invention will solve existing lock body can not prepare space pattern, inefficiency, shortcoming that mismachining tolerance is big at the lock body external surface, the lockmaking method that provide a kind of can prepare space pattern on lock body, lock body can be made various design shapes, lock core die cavity mismachining tolerance is little, efficient is high.
The processing method of a kind of lock body of the present invention comprises following manufacturing step:
(1) opens according to pattern, the shape of lock body and neutralize casting mould; The use method designing mould of loosing core is reserved the die cavity of lock core;
(2) the alloy material liquation is injected mould, utilize hot chamber machine to carry out die casting, make lock body and inner die cavity one-shot forming;
(3) assembling lock core, lock ring, spring, key bow;
(4) surface of lock body is handled.
Described alloy material is an allumen.
Described surface of lock body is handled and is comprised plating or plating.
Advantage of the present invention is that surface of lock body can produce various plastic relief formula patterns; The global shape of lock body has also been broken through the longitudinal profile style, can make the shape of any imagination; The disposable die cast of lock core die cavity and lock body, accurate positioning, standard degree height not only helps raising the efficiency but also help improving the quality; Also help the minimizing metal loss, save cost; The various processing such as can electroplate, spray paint of alloy surface of lock body increase color.
4. description of drawings
Manual of the present invention does not have accompanying drawing.
5. the specific embodiment
The processing method of a kind of lock body of the present invention comprises following manufacturing step:
(5) open according to pattern, the shape of lock body and neutralize casting mould; The use method designing mould of loosing core is reserved the die cavity of lock core;
(6) the alloy material liquation is injected mould, utilize hot chamber machine to carry out die casting, make lock body and inner die cavity one-shot forming;
(7) assembling lock core, lock ring, spring, key bow;
(8) surface of lock body is handled.Comprise deburring, polishing, cleaning, plating.
Described alloy material is an allumen.
Described surface of lock body is handled and is comprised plating or plating.
Claims (4)
