Abstract
The invention discloses an automobile ignition key and a machining method thereof, and aims to solve the problems that a key has defects, because a key blank is a stamped part, one side of a cross section of a key bar has a natural rounded corner while the other side of the cross section of the key bar has a sharp corner inevitably, production efficiency is low, and the machining processes are complicated. According to the technical scheme adopted by the invention, the automobile ignition key is composed of the key blank and a mark block, wherein the mark block is composed of two injection molding blocks which are connected through a soft connecting belt; the two injection molding blocks are fastened together; and a cross positioning shaft and a cross positioning slot are separately arranged inside each of the two injection molding blocks. The automobile ignition key has the advantages that the inevitable defect that the two surfaces of the stamped part are inconsistent is eliminated; and the brand identity of the automobile manufacturer and a rubber-covered body can show different colors so as to achieve different appearance effects. The automobile ignition key further has the characteristics of simple structure, simplicity and convenience in operation, good appearance color marking effect, and the like.
Description
Technical field
The present invention relates to automotive ignition key technical field, particularly to a kind of automotive ignition key and processing method thereof.
Background technology
At present, general automotive ignition Key for lock all adopts the encapsulated making of key billet.Wherein, key billet copper-nickel alloy plate is stamped to form, and its head is in the lamellar more smaller than encapsulated body profile, and outputs a breach, in order to the fixing theftproof chip wrapped with little plastic box in advance, and the encapsulated body ultimately formed generally has the brand identity pattern of auto vendor.
The weak point of this scheme, one is the outward appearance flaw to some extent of key, because key billet is stamping parts, key bar section necessarily presents while being nature fillet, another side is the state of wedge angle, although by tempering, the technique such as grinding can make moderate progress, but can not be inherently eliminated this phenomenon, and add production process and cost；The amount of copper consuming being exactly additionally product is relatively big, and cost of manufacture is higher；3rd is that production efficiency is slightly lower, its substantially process be first wrap theftproof chip with little plastic box, then these assembly parts are fixed on key billet, finally encapsulated.Which results in manufacturing procedure loaded down with trivial details, cost of manufacture is higher.
Summary of the invention
For solving above-mentioned technical problem, the present invention proposes a kind of automotive ignition key and processing method thereof.
The technical solution adopted in the present invention is: it includes: key billet, it is characterized in that: key is made up of key billet and attribute block, described attribute block is made up of two two injection moulding blocks being flexible coupling with connecting, two of which injection moulding block snaps together, and is respectively arranged with cross locating shaft, cross locating slot inside two injection moulding blocks；The inside of two injection moulding blocks is also respectively provided with key billet locating piece, key billet locating slot, key billet locating piece and be provided with four water conservancy diversion around key billet locating slot and fill holes；Car mark boss it is provided with outside two injection moulding blocks；It is additionally provided with chip slot inside one injection moulding block.Reverse tripper it is additionally provided with in attribute block.
The processing method of automotive ignition key, comprises the following steps:
1) prefabricated rectangle key billet section bar；
2) undertaken key billet section bar being stretched to key finished product profile and carrying out polish becoming the fluted anodontia key billet of band, stand-by；
3) preparing attribute block mould, attribute block mould is injection mold；
4) to attribute block injection mo(u)lding, stand-by after being cooled to room temperature；Cool time is one hour: described room temperature is 25 DEG C, and humidity is 60%.
5) it is placed in two injection moulding blocks of attribute block with fluted anodontia key billet, and makes the hole, location of key billet insert in the key billet locating piece of injection moulding block, theftproof chip is placed in the chip slot of injection moulding block；Being snapped together by two injection moulding blocks, key billet locating piece and key billet locating slot match, and cross locating shaft and cross locating slot cooperate；
6) by after step 5) fastens with the injection moulding block of key billet closely after carry out encapsulated；
7) it is provided with the car mark agreed with mutually with car mark boss in encapsulation die protruding, makes glue will not be coated with car mark boss.
8) take out after colloid solidification stand-by.
Advantages of the present invention and providing the benefit that: key billet section is that rectangular section bar draws, and contraction in length, decrease amount of copper consuming, reduce production cost, its section net shape is determined by special rectangular broach, therefore, key bar appearance stablity is consistent, eliminates the flaw that two sides that stamping parts necessarily has is inconsistent；The brand identity that can also allow auto vendor presents different colors from encapsulated body, to reach different appearance.The present invention also has simple in construction, easy and simple to handle, the features such as appearance color mark action is strong.

Detailed description of the invention
Referring to Fig. 1 ~ 6, key is made up of key billet 1 and attribute block 2, and described attribute block is flexible coupling by two and forms with 3 two the injection moulding blocks 4 connected, and two of which injection moulding block snaps together, and is respectively arranged with cross locating shaft 5, cross locating slot 6 inside two injection moulding blocks；The inside of two injection moulding blocks is also respectively provided with key billet locating piece 7, key billet locating slot 8, key billet locating piece and be provided with four water conservancy diversion around key billet locating slot and fill holes 9；The boss 10 with car mark 13 it is provided with outside two injection moulding blocks；It is additionally provided with chip slot 11 inside one injection moulding block.Reverse tripper it is additionally provided with in attribute block.
The processing method of automotive ignition key, comprises the following steps:
1) prefabricated rectangle key billet section bar；
2) undertaken key billet section bar being stretched to key finished product profile and carrying out polish becoming the fluted anodontia key billet of band, stand-by；
3) preparing attribute block mould, attribute block mould is injection mold；
4) to attribute block injection mo(u)lding, stand-by after being cooled to room temperature；Cool time is one hour: described room temperature is 25 DEG C, and humidity is 60%.
5) it is placed in two injection moulding blocks of attribute block with fluted anodontia key billet, and makes the hole 12, location of key billet insert in the key billet locating piece of injection moulding block, theftproof chip 14 is placed in the chip slot of injection moulding block；Being snapped together by two injection moulding blocks, key billet locating piece and key billet locating slot match, and cross locating shaft and cross locating slot cooperate；
