Only need carry out the rubber coating once, simple structure, production flow is simple and convenient, shortens the shaping cycle of mechanical key greatly, has improved production facility's utilization ratio, and wherein plastic handle accessible horizontal injection molding machine shaping, mould can open a mould multicavity, then rethread vertical injection molding machine is in the same place with key base and plastic handle and rubber coating packing shaping, improves production efficiency greatly.
Description
Technical Field
The utility model relates to the technical field of automobile part production, in particular to an automobile straight shank key with simplified encapsulation.
Background
When an automobile key is produced, a key blank made of metal and a plastic handle are fixedly connected, and the prior art generally adopts an encapsulation injection molding process, for example, chinese patent CN202359889U discloses an automobile ignition key mechanism with an engine anti-theft chip, and the automobile ignition key mechanism comprises a handle, a metal tooth body and a bracket, wherein the bracket is connected with the metal tooth body and encapsulated in the handle. For the requirements of beauty, hand feeling and the like, the handle of the key has the range requirements of certain size and thickness, and if the thickness of the handle is bigger, the injection molding process is not well controlled, and the conditions of shrinkage of the encapsulated filler, unsmooth appearance and the like can be caused, so that the yield is not high, and the key can be formed by secondary encapsulation, as shown in figure 1: the filler A is attached to the key blank through primary encapsulation, and the filler B is attached to the primary encapsulated component through secondary encapsulation, so that the yield of products is improved. However, the process needs to carry out secondary encapsulation on a vertical injection molding machine, needs to carry out 2 times of die replacement or adopts two devices for injection molding, and has long production period, excessive occupied devices and low production efficiency.
Disclosure of Invention
The utility model aims to provide an automobile straight shank key with simplified encapsulation. According to the utility model, the straight shank key of the automobile is optimized, only one layer of rubber coating filler is covered, and the efficiency is improved while the product qualification rate is not influenced.
The technical scheme of the utility model is as follows: a simplified encapsulated automobile straight shank key comprises a key blank, wherein a plastic handle is connected to the key blank, and encapsulated fillers are arranged outside the key blank and the plastic handle.
The automobile straight shank key with the simplified rubber coating is characterized in that the key blank is provided with the boss, the plastic handle is inserted into the boss to limit the position, the plastic handle is provided with the groove, and the positioning rib is arranged in the groove.
The automobile straight shank key with the simplified rubber coating is characterized in that the boss is provided with a hole, and the plastic handle is provided with a through hole aligned with the hole.
The beneficial effects are that: according to the mechanical key structure, after a key blank and a plastic handle are assembled together, the key blank is used as an insert for encapsulation and injection molding. Only need carry out the rubber coating once, simple structure, production flow is simple and convenient, shortens the shaping cycle of mechanical key greatly, has improved production facility's utilization ratio, and wherein plastic handle accessible horizontal injection molding machine shaping, mould can open a mould multicavity, then rethread vertical injection molding machine is in the same place with key base and plastic handle and rubber coating packing shaping, improves production efficiency greatly.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting. Conventional prior art in the art is available for structures or processes that are not specifically identified.
Examples
A simplified encapsulated automobile straight shank key comprises a key blank 1, wherein a plastic handle 2 is connected to the key blank 1, and an encapsulated filler 3 is arranged outside the key blank 1 and the plastic handle 2. The plastic handle 2 is formed by a horizontal injection molding machine, then is connected with the key blank 1 made of metal, and is subjected to an encapsulation process by a vertical injection molding machine, and the key blank 1 and the plastic handle 2 are wrapped with an encapsulation filler 3 and fixed together.
Further, the boss 4 of the plastic handle 2 is inserted into the key blank 1, the groove 6 is formed in the plastic handle 2, the positioning rib 7 is arranged in the groove 6, the key blank 1 is inserted into the groove 6 of the plastic handle 2, the insertion depth of the key blank 1 can be limited through the boss 4, and the key blank 1 is clamped through the positioning rib 7.
The boss 4 is provided with a hole 5, the plastic handle 2 is provided with a through hole 8, after the key blank 1 is inserted into the groove 6 of the plastic handle 2, the hole 5 is aligned with the through hole 8, and when injection molding is performed, filler can be filled into the hole 5 and the through hole 8 to fix the key blank 1 and the plastic handle 2 firmly and prevent the key blank 1 and the plastic handle 2 from falling off.
