[0002] A die-casting mold is a tool for casting metal parts. The die-casting process is usually completed on a dedicated die-casting forging machine. The basic process of die-casting is: the molten metal is first cast and filled into the mold cavity at a low or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools, eliminating the shrinkage defects of the blank and making the internal structure of the blank reach the broken grains in the forged state. Therefore, during the use of the die-casting mold, it is necessary to ensure the mold closing pressure of the die-casting mold. However, after long-term use, the mold closing pressure of most die-casting molds will deteriorate, resulting in flash on the die-cast products, thereby affecting the product qualification rate.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, the integrated die-casting mold for new energy vehicles of the present invention includes a movable mold 100 , a cavity 110 , a runner 200 , a first reserved channel 300 and a second reserved channel 400 .

[0022] In the present invention, the die-casting mold further includes a static mold 500 , and a liquid inlet pipe 510 is further provided on the static mold 500 .

[0023] A cavity 110 is provided on one side of the movable mold 100, and the movable mold 100 is provided with at least one branch channel 200 connected to the cavity 110 on one side of the cavity 110, and the movable mold 100 is also provided with at least one first reserved channel 300 and at least one second reserved channel 400 on one side of the cavity 110, the first reserved channel 300 and the second reserved channel 400 are both connected to the cavity 110, the first reserved channel 300 is located between the second reserved channel 400 and the branch channel 200, the first reserved channel 300 is not connected to the adjacent branch channel 200, the first reserved channel 300 is not connected to the adjacent second reserved channel 400, and a liquid separation nozzle 120 is provided on the movable mold 100, the liquid separation nozzle 120 is located between the two branch channels 200, and the liquid separation nozzle 120 is located between the two branch channels 200. 0 A liquid separation port 121 connected to the branch channel 200 is provided on the side facing the cavity 110, the first reserved channel 300 is connected to the cavity 110 through the first branch channel 320, and the second reserved channel 400 is connected to the cavity 110 through the second branch channel 420. When the first reserved channel 300 is not connected to the adjacent branch channel 200, a first blocking block 310 is provided between the first reserved channel 300 and the adjacent branch channel 200; when the first reserved channel 300 is not connected to the adjacent second reserved channel 400, a second blocking block 410 is provided between the first reserved channel 300 and the adjacent second reserved channel 400, a push block (not marked in the figure) for pushing the liquid material to move is movably provided in the liquid inlet pipe 510, and an exhaust channel 170 connected to the cavity 110 is provided on the movable mold 100.

[0024] When using the die-casting mold, the first barrier block 310 and the second barrier block 410 are retained first, and the die-casting work of the mold is performed once. The specific steps are as follows: people need to contact the movable mold 100 with the static mold 500, and connect the liquid inlet pipe 510 with the liquid separation nozzle 120. Thereafter, the push block is controlled to push the liquid material in the liquid inlet pipe 510 so that the liquid material in the liquid inlet pipe 510 is smoothly squeezed into the diverter channel 200. Since the diverter channel 200 is connected with the cavity 110, the liquid material can be smoothly pushed into the cavity 110. At the same time, , the air in the cavity 110 will be discharged to the outside of the mold through the exhaust duct 170, thereby reducing the probability of bubbles appearing in the die-cast product. In this process, since the first reserved channel 300 and the second reserved channel 400 are both connected to the cavity 110, the gas or liquid material mixed with gas flowing out of the cavity 110 will enter the first reserved channel 300 or the second reserved channel 400 nearby, further reducing the probability of bubbles appearing in the die-cast product. If the die-cast product meets the design requirements, there is no need to remove the first barrier block 310 and the second barrier block 410.

[0025] The number of branch channels 200, the number of first reserved channels 300 and the number of second reserved channels 400 are all two. The two first reserved channels 300 are respectively located on both sides of the cavity 110, the two second reserved channels 400 are respectively located on both sides of the cavity 110, and the two branch channels 200 are respectively located on both sides of the cavity 110. The central angle of the branch channel 200 is greater than or equal to 90°.

[0026] Each of the branch channels 200 is connected to the mold cavity 110 through a first liquid inlet channel 130, multiple second liquid inlet channels 140 and a third liquid inlet channel 150. The second liquid inlet channel 140 is located between the first liquid inlet channel 130 and the third liquid inlet channel 150. When the liquid separation nozzle 120 introduces liquid material into the branch channel 200 through the liquid separation port 121, the liquid material will flow along the trajectory of the branch channel 200 in the direction away from the liquid separation nozzle 120. During this process, the liquid material will enter the mold cavity 110 through the first liquid inlet channel 130, the second liquid inlet channel 140 and the third liquid inlet channel 150 in turn.

[0027] Furthermore, when the liquid material flows along the trajectory of the branch channel 200 away from the liquid separation nozzle 120, the liquid material will enter the mold cavity 110 through the first liquid inlet channel 130, the second liquid inlet channel 140 and the third liquid inlet channel 150 in sequence. Therefore, in the process of the liquid material flowing in the direction away from the liquid separation nozzle 120, the pressure on the inner wall of the branch channel 200 will gradually weaken. In the present utility model, a drainage block 160 is provided in the second liquid inlet channel 140 and the third liquid inlet channel 150. Each drainage block 160 is arranged at the entrance of the second liquid inlet channel 140 or the third liquid inlet channel 150, so as to smoothly guide the liquid material into the corresponding liquid inlet channel.

[0028] Example 2:

[0029] The difference between this embodiment and the first embodiment is that this embodiment changes the connection relationship between the first reserved channel 300 and the adjacent branch channel 200 and changes the connection relationship between the first reserved channel 300 and the adjacent second reserved channel 400.

[0030] In the present invention, flash refers to the residual material edge left on the plastic part due to insufficient mold clamping pressure, which causes liquid material to overflow into the gap between the movable mold 100 and the static mold 500 and the cavity 110 not surrounded by the diverter 200 during the molding process.

[0031] Specifically, the first reserved channel 300 is communicated with the adjacent branch channel 200 , and the first reserved channel 300 is communicated with the adjacent second reserved channel 400 .

[0032] When flash appears on the die-cast product, people can remove the first barrier block 310 and the second barrier block 410 on the movable mold 100 at the same time, so that the diverter channel 200, the first reserved channel 300 and the second reserved channel can be connected at the same time. In this way, it is equivalent to increasing the central angle of the diverter channel 200, that is, the periphery of the cavity 110 except for the exhaust channel 170 will be surrounded by the diverter channel 200, the first reserved channel 300 and the second reserved channel 400, so that the flowing material can pressurize the periphery of the cavity 110 except for the exhaust channel 170, thereby effectively reducing the occurrence of flash on the product; further, the first barrier block 310 and the second barrier block 410 can be removed by stamping or flushing.

[0033] When people remove the first blocking block 310 and the second blocking block 410, the liquid material in the branch channel 200 will flow to the first reserved channel 300 and the second reserved channel 400. After that, the liquid material in the first reserved channel 300 will flow into the mold cavity 110 through the first branch channel 320, and the liquid material in the second reserved channel 400 will flow into the mold cavity 110 through the second branch channel 420.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0036] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
