Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a vacuum die-casting mold for a heating core of a new energy automobile. Background Art

[0002] The main task of the battery temperature management system is to ensure that the battery pack operates within a safe range, provide the necessary information required for vehicle control, respond promptly when an abnormality occurs, and determine the battery's charge and discharge power based on ambient temperature, battery status, and vehicle requirements. Battery heat-related issues are key factors in determining their performance, safety, life, and cost of use.

[0003] The heating core is the core component of the battery temperature management system. When the product cavity is relatively deep, some air will remain in the cavity during casting, causing air entrapment in the product and bubbling of the die-casting. Therefore, vacuum die-casting is required. However, traditional vacuum die-casting molds mainly use a parting surface vacuum extraction mode and a vacuum valve. If the time to close the vacuum valve is not well controlled, the aluminum liquid will easily splash into the vacuum valve, causing damage to the vacuum valve, resulting in cost waste and product instability.

[0004] Therefore, it is necessary to invent a vacuum die-casting mold for the heating core of a new energy vehicle. Utility Model Content

[0005] To this end, the utility model provides a vacuum die-casting mold for a heating core of a new energy vehicle.

[0007] Preferably, the shaping component includes a fixing frame, which is symmetrically fixed at both ends of the fixed mold, and the side ends of the fixing frame are fixed with cylinders, the cylinder output shafts are fixed with fixed modules, the fixed modules are slidably connected to the top of the partition, and the heating core is located between the fixed modules.

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] Please refer to the attached Figure 1-4 The utility model provides a vacuum die-casting mold for a heating core of a new energy vehicle, comprising a fixed mold 1, a movable mold 2 and a heating core 3. The movable mold 2 is connected to a driving device such as a hydraulic cylinder. A feed port 4 is provided on the movable mold 2. A cavity 6 is provided at the center of the top of the fixed mold 1. Guide sleeves 5 are vertically provided at the four corners of the top of the fixed mold 1. A partition 7 is fixed inside the cavity 6. Molding components are symmetrically provided on both sides of the fixed mold 1. A vacuum pumping component is provided inside the fixed mold 1.

[0019] The shaping assembly includes a fixing frame 8, which is symmetrically fixed at both ends of the fixed mold 1. The side ends of the fixing frame 8 are fixed with cylinders 9, and the output shafts of the cylinders 9 are fixed with fixed modules 10. The fixed modules 10 are slidably connected to the top of the partition 7, and the heating core 3 is located between the fixed modules 10. Specifically, when the cylinders 9 are running, the fixed modules 10 can be driven to move, thereby facilitating the shaping of the heating core 3.

[0020] The vacuum pumping assembly includes a suction pipe 11. It should be noted that the suction pipe 11 is connected to an external vacuum generator (not shown in the figure). The suction pipe 11 is vertically fixed at the bottom of the fixed mold 1. A plurality of suction holes 12 are provided at the bottom of the inner wall of the cavity 6. The top of the suction pipe 11 is connected to the interior of the cavity 6 through the plurality of suction holes 12. A plurality of suction holes 13 are evenly provided on the partition plate 7. The interior of the movable mold 2 is connected to the interior of the cavity 6 through the plurality of suction holes 13. Specifically, when the external vacuum generator is running, the interior of the movable mold 2 and the interior of the fixed mold 1 after mold closing can be vacuumed through the suction pipe 11. That is, by adopting the method of vacuuming the entire mold, the high air tightness of the heating core die-casting component is achieved, without the need for a vacuum valve, and the whole process adopts continuous vacuuming, so that the aluminum liquid will not splash.

[0023] The use process of the utility model is as follows: when in use, the technicians in this field first control the fixed mold 1 and the movable mold 2 to perform a mold closing operation. After the mold is closed, the technicians in this field control the operation of the external vacuum generator, and vacuumize the inside of the movable mold 2 and the fixed mold 1 after the mold is closed through the suction pipe 11, that is, by adopting the method of vacuuming the entire mold, the high air tightness of the heating core die-casting component is achieved, no vacuum valve is required, and continuous vacuuming is adopted in the whole process, and the aluminum liquid will not splash. Then, the material is fed through the feed port 4, and the cylinder 9 is controlled to operate and the fixed module 10 is controlled to move, so that the heating core 3 is finalized in the cavity 6.
