[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 7 This utility model provides a technical solution: an injection mold for processing H-beam coils, including a middle mold 1, a top mold 2, and a bottom mold 3. Guide grooves 4 are provided at both top corners of the middle mold 1. Guide pillars 5 are installed on the closed surfaces of the top mold 2 and the bottom mold 3. There are four guide pillars 5. When the four guide pillars are aligned with the guide grooves 4, the middle mold 1, top mold 2, and bottom mold 3 can be effectively connected. The top mold 2 and bottom mold 3 are closed within the middle mold 1 by the guide pillars. The upper part forms a mold cavity. The bottom mold 3 has a base mold 6 fixedly installed in the middle. The inside of the base mold 6 is a groove. The middle mold 1 has a top mold 7 fixedly installed on one side. The inner side wall of the top mold 7 is also provided with a protrusion. During molding, it can form a slot for the top plate, so as to facilitate the effective engagement of the two parts of the coil. The middle mold 1 also has hook molds 8 installed on both sides. The hook molds 8 can prepare hooks, so as to facilitate the effective fixation of the coil. The side wall of the top mold 2 is also provided with a pusher 9 to drive the hook mold 8 to close.

[0025] As a preferred embodiment, based on the above method, the side walls of the top mold 2 and the bottom mold 3 are further provided with injection pipes 10. The injection pipes 10 penetrate the top mold 2 and the bottom mold 3 and extend to the inner walls of the top mold 2 and the bottom mold 3. In actual production, the injection pipes 10 can directly inject raw materials, and the raw materials can be directly injected into the middle mold, the top mold and the bottom mold through the injection pipes 10.

[0026] The intermediate mold 1 is equipped with a cooling structure, which includes a coolant injection pipe joint 101 and a coolant discharge pipe joint 102 fixedly connected to the top of the intermediate mold 1, and a cooling pipe 103 installed on the inner side wall of the intermediate mold 1. In actual use, the coolant injection pipe joint 101 and the coolant discharge pipe joint 102 need to be connected to a supply device. The supply pump draws in the coolant and delivers it to the coolant injection pipe joint 101. After passing through the flow channel of the cooling pipe 103, it is discharged through the coolant discharge pipe joint 102, thereby achieving the purpose of cooling the intermediate mold 1.

[0027] The cooling pipe 103 is arranged in a spiral shape on the inner side wall of the middle section mold 1 and fits into the molding cavity of the middle section mold 1. The cooling pipe 103 is arranged in a spiral shape in the middle section mold 1, thereby prolonging the time of the coolant in the middle section mold 1 and achieving the purpose of effectively cooling the middle section mold 1.

[0028] As a preferred embodiment, based on the above method, the pusher 9 is further defined as a protrusion fixedly connected to the side wall of the top mold 2. The inner side wall of the protrusion has an inclined surface, and the pusher 9 has an inclined surface, so as to facilitate the formation of a lateral thrust when contacting the hook mold 8, thereby achieving the purpose of driving the hook mold 8.

[0029] The hook mold 8 includes a slide rail 81 fixedly connected to the side wall of the middle mold 1. A slide table 82 is slidably installed on the inner side wall of the slide rail 81. One end of the slide table 82 has a hook groove 83. When the slide table 82 is in contact with the outer wall of the middle mold 1, it can be used to form a hook. The slide table 82 can slide horizontally in the slide rail 81, thereby achieving the purpose of opening and closing the hook groove 83.

[0030] A slide rod 85 is fixedly connected to one side of the slide table 82. One end of the slide rod 85 extends out of the slide rail 81 and has a disc. A spring 84 is also fitted on the outer wall of the slide rod 85. The two ends of the spring 84 are fixedly connected to the disc and the slide table 82 respectively. The spring 84 has an elastic potential energy to return to its original position when compressed, which causes the slide table 82 to open automatically.

[0031] In summary, when using the injection mold processed by the I-beam coil, the guide posts 5 of the side arms of the top mold 2 and the bottom mold 3 are aligned with the guide grooves 4. Then, the middle mold 1, the top mold 2, and the bottom mold 3 are closed to form an injection cavity. The raw material can be injected into the mold through the injection pipe 10. The raw material is formed in the cavity of the mold. When the top mold 2 is closed on the middle mold 1, the pusher 9 will push the hook mold 8 to close on the middle mold 1 to form a hook. When the top mold 2 is disassembled, the spring 84 can push the slide table 82 to automatically reset, thereby opening the restriction on the hook and allowing the molded mold to be easily removed. At the same time, during molding, coolant can be delivered to the middle mold 1 through the coolant injection pipe joint 101 and the coolant discharge pipe joint 102 to cool and shape it.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
