Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for injection molding a door lock member, in particular, to inject a soft gel having a lower temperature into a higher temperature injection mold. A method of forming a door lock member by rapidly hardening it. [Prior Art] It has become increasingly common to use magnetic door locks. The existing magnetic door locks are mounted on the top of the door with an electromagnet that is attached to the iron plate phase 5 at a relative position of the door frame. The secondary electromagnet is mainly composed of an iron core and a coil wound around the iron core, and then a protective body is provided on the outer circumference to ensure that the coil can be firmly coupled to the iron core. In the practice of using a protective body, the combined iron core and the coil are placed in the long mold set, and then the glue is poured into the mold shell to completely coat the iron core and the coil element. And the glue is protruded above the mold shell. After the glue is solidified, the mold shell is peeled off and the glue protruding on the mold shell is processed by the implement to the iron core to expose the outer surface, and finally The surface of the core is subjected to grinding and processing. However, the investigation of the "manufacturing method of such an electromagnet" will result in the following defects in the implementation process: Each of the stripped mold shells cannot be reused and must be discarded, resulting in a waste of resources. 'The winning agent used for sealing is a kind of liquid. After it is poured into the mold shell, the whisker will harden for a long time, so the production speed is slow. Moreover, after the liquid agent is hardened, its heat resistance is poor. Arrived at 7〇~8 (rc begins to soften, when the electromagnet is energized, it will produce a temperature rise.) Therefore, the type is sealed (four), so its fire resistance is poor. -3- [s] 201209262 For this reason, the industry does not address the problem. Point, propose an improvement method. The reason is that in 1991, Taiwan’s "7059 patent proposed a combination of the injection of the coil and the injection molding of the injection machine, and then combined with the iron core β followed by the applicant in 1997" After the iron core and the coil are combined, they are placed in the mold, and the injection machine is injection molded. However, the method of injecting and forming the insulating protective colloid can eliminate the upper mold shell, thereby reducing the processing time and cost; In the method, the iron core and the coil are combined and placed in an injection molding die, and then the high temperature molten plastic material is injected into the molding die by an injection machine. However, since the iron core and the coil system are made of a metal material, physical properties thereof are obtained. Not with plastic materials at all

The stability of the molded part after molding will be reduced or even impossible to use at all. To this end, some manufacturers have previously applied a layer of bonding agent on the surface of the core and the coil (for example, simple to enhance the bonding with its plastic interface. But the coating agent, non-ff time ^ this: does not meet economic and industrial needs Moreover, the plastic injection molding locks, the first two only about: ° ~ thief around (four) began to soften, so the service life and reliability are not good, therefore, there is still room for improvement.
