Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold. Background Art

[0002] Injection molds are divided into two types according to molding characteristics: thermosetting plastic molds and thermoplastic plastic molds. According to the molding process, they are divided into transfer molds, thermoforming molds, hot pressing molds, injection molds, etc., among which hot pressing molds can be divided into three types according to the overflow method: overflow type, semi-overflow type, and non-overflow type. After searching, a Chinese patent with authorization announcement number CN218803757U discloses an injection mold, including a bottom plate, and the upper surface of the bottom plate is respectively provided with a left mold and a right mold, and the left mold and the right mold can fit each other. A U-shaped plate 1 is fixedly installed on the outer side of the left mold, and a driving motor is installed on the outer side of the U-shaped plate 1. A screw is connected to the rotating shaft of the driving motor, and a movable ring sleeve is meshed with the outer side of the screw through a thread, and a fixing piece is fixedly installed on the outer side of the movable ring sleeve. The utility model is provided with a needle, so that when the left mold and the right mold are about to fit together, the hot glue expands on the outside, and after the driving motor is started, the movable ring sleeve can be moved on the outside of the screw, and then one end of the needle can directly puncture the outside of the expanded hot glue, and then the gas inside the hot glue is released. The device can effectively and automatically discharge the gas inside the hot glue without the need for human operation.

[0003] However, in the actual use of this solution, the gas released from the hot glue will carry high temperature. At the same time, the adsorption performance of activated carbon will change with the temperature. When the temperature rises, the adsorption capacity of activated carbon will decrease because its pore structure will expand, which directly reduces the filtering effect of the activated carbon plate on the gas, which is not conducive to the safe emission of gas.

[0004] Therefore, we made improvements to this and proposed an injection mold. Utility Model Content

[0005] In order to solve the problem that the activated carbon plate in the existing injection mold is easily affected by high temperature, the utility model provides an injection mold.

[0014] Furthermore, the air extraction mechanism includes a cylinder, a cylinder cover, a circular frame, a plurality of filter holes and a negative pressure fan.

[0019] Furthermore, the top end of the left mold is threadedly connected with a bolt, and the left mold is connected with a pair of fixed angle plates through the bolts, and one side of the pair of fixed angle plates is respectively connected to the two sides of the ventilation box.

[0020] The beneficial effect of adopting the above further solution is that, by using the connection of the fixed angle plate, it is convenient to fix the ventilation box on the top end of the left mold.

[0021] Furthermore, the bottom end of the ventilation box is flush with the top end of the right mold.

[0022] The beneficial effect of adopting the above further solution is that, by utilizing the positional relationship between the ventilation box and the right mold, it is avoided that the ventilation box hinders the engagement activity of the mold body.

[0023] The beneficial effect of the utility model is that through the coordinated use of the ventilation box, the cooling component, the exhaust mechanism and the filter component, the injection mold can realize the function of cooling the high-temperature airflow, thereby reducing the influence of the high-temperature airflow on the activated carbon plate, wherein, through the connection between the water inlet port and the folded copper tube, the interior of the folded copper tube can be connected to sufficient cooling liquid, and in conjunction with the installation and use of the thin aluminum plate, the low temperature can be diffused, which is convenient for cooling the high-temperature airflow passing through the thin aluminum plate, thereby avoiding the adverse effects of high temperature on the activated carbon plate in the filter component, and then through the installation and use of the exhaust mechanism, it is helpful to speed up the circulation of the airflow, thereby improving the circulation efficiency of the airflow inside the ventilation box.

At the same time, the frame 4003 drives the activated carbon plate 4004 to slide on the two rails 4002, so that it is convenient to replace the activated carbon plate 4004, and then through the filtration of the activated carbon plate 4004, the passing gas can be effectively filtered, thereby reducing the pollution of the gas to the air. At the same time, through the connection diagram of the two magnetic blocks, it is convenient to fix the frame 4003 at the specified position inside the rail 4002 to keep the activated carbon plate 4004 stable.

[0040] It should be noted that the specific model and specifications of the negative pressure fan 3005 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field. Secondly, the cross-sectional size of the thin aluminum plate 6001 is large enough, and the space through which the airflow passes is long enough, which can effectively reduce the temperature of the airflow, so it will not be described in detail.
