[0017] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0018] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0019] The present utility model provides a die for metal die-castings, which includes a base 1. Guide posts 101 are symmetrically installed on the base 1. A vertical frame 2 is arranged between adjacent guide posts 101. A female die 201 is fixedly connected to the vertical frame 2. It is characterized in that a fixed plate 3 is fixedly connected to the guide post 101. A die-casting machine lower pressure housing 4 is fixedly connected to the fixed plate 3. A lower pressure rod 401 is slidably connected in the die-casting machine lower pressure housing 4. A male die 5 is fixedly connected to the bottom of the lower pressure rod 401. The male die 5 and the female die 201 are fitted with each other. Forming cavities 501 are arranged in both the male die 5 and the female die 201. A retention cavity 502 is arranged at the position of the forming cavity 501 of the male die 5. The forming cavity 501 and the retention cavity 502 are connected by a pipeline 503. A molten material supply port 504 is installed at the top of the male die 5. A runner 505 is embedded in the male die 5. The molten material supply port 504 is communicated with the runner 505. A plurality of groups of nozzles 506 are evenly distributed on the inner wall of the male die 5. The nozzles 506 and the runner 505 are communicated with each other. An air outlet 507 is arranged on the male die 5. An electromagnetic valve 508 is arranged on the pipeline 503. The retention cavity 502 and the air outlet 507 are connected by an air pipe 509, which is convenient for guiding the gas in the retention cavity 502 to the position of the air outlet 507 through the air pipe 509 and finally discharging it from the male die 5;

[0020] When the metal die-casting mold is actually in use, an operator operates the die-casting machine to press down the pressing rod 401 in the housing 4, driving the punch 5 downward until the abutting blocks 602 at the bottom of the rectangular plates 601 on both sides of the punch 5 abut against the positioning plate 6. At this time, the punch 5 and the die 201 are in a relatively abutting and sealed state. Then, the operator feeds the molten material into the runner 505 in the punch 5 through the molten material supply port 504. Then, the molten material is injected from multiple nozzle positions 506 into the molding cavity 501 between the punch 5 and the die 201. When the molding cavity 501 between the die 201 and the punch 5 is filled with the molten material, the supply is stopped and it stays in the punch 5 in the die 201 for a period of time. Then, the operator controls the solenoid valve 508 on the pipeline of the punch 5 to open, discharging the high-pressure gas remaining in the die 201 and the punch 5 into the retention cavity 502. Then, in cooperation with the air pipe 509, the gas generated between the die 201 and the punch 5 is guided to the air outlet 507 position, and finally discharged from the air outlet 507. By providing a retention cavity 502 in the punch 5 and a structure with a pipeline 503 and an internal solenoid valve 508, the gas formed in the molding cavity 501 is introduced into the retention cavity 502, and finally the gas is guided to the air outlet 507 position by the air pipe 509. Compared with the exhaust structure and discharge method of conventional molds, the solenoid valve 508 is made of high-temperature resistant material. The technical solution adopted by the present utility model can discharge the high-temperature gas generated during the die-casting process in a timely and efficient manner, which is beneficial to improving the product quality. The overall structure is compact, easy for the operator to install and maintain, and the overall structure is directly installed in the existing working space, optimizing the existing space structure.

[0021] As Figures 1-3 shown, positioning plates 6 are fixedly connected to both sides of the die 201. Rectangular plates 601 are installed on both sides of the punch 5. Abutting blocks 602 are fixedly connected to the bottom of the rectangular plates 601. The abutting blocks 602 abut against the positioning plates 6. Both the punch 5 and the die 201 are made of high-temperature resistant material.

[0022] The effect achieved by the entire Example 1 is that during use, the pressing rod 401 in the housing 4 of the die-casting machine is used to drive the punch 5 downward until the abutting blocks 602 at the bottom of the rectangular plates 601 on both sides of the punch 5 abut against the positioning plates 6. At this time, the punch 5 and the die 201 are in a relatively abutting and sealed state. The positioning plates 6 and the abutting blocks 602 cooperate with each other to complete the limiting work between the punch 5 and the die 201.

[0023] Working principle: Through the pipeline and the built-in solenoid valve structure, the gas formed in the forming cavity is introduced into the retention cavity, and finally the gas is guided to the air outlet position by the trachea. Compared with the exhaust structure and discharge method of conventional molds, the solenoid valve is made of high-temperature resistant materials. The technical solution adopted by the present utility model can discharge the high-temperature gas generated during the die-casting process in a timely and efficient manner, which is beneficial to improving the quality of the product. The overall structure is compact, easy for staff to install and maintain, and the overall structure is directly installed on the existing working space, optimizing the existing space structure.
