[0032] Example 1

[0033] like Figure 1-6 As shown, the utility model proposes a die-casting mold for a new energy vehicle drive motor housing, comprising a mold A1, an insert 12, a mounting plate 3, a demoulding assembly 4, a hydraulic rod 5 and a feed port 6;

[0034] There are multiple inserts 12, all of which are installed inside the mold A1. A mold B2 is provided on the side of the mold A1 for moving toward the mold A1 and closing the mold A1 when in use. The feed port 6 is installed at the top of the mold A1 and communicates with the mold A1.

[0035] The hydraulic rod 5 is mounted on the side of the mounting plate 3, and the piston rod of the hydraulic rod 5 passes through the mounting plate 3 and is connected to the mold B2. When in use, the mold B2 is moved toward the mold A1 and the mold B2 is inserted into the inner side of the mold A1, so that the molds A1 and B2 are in a closed mold state.

[0036] The demoulding assembly 4 is mounted on the mounting plate 3 and the mold B2, and its end is connected to the insert 12 for fixing the end of the insert 12 and demoulding the motor housing when in use.

[0037] In an optional embodiment, the mold A1 includes a mold A body 11;

[0038] The mold A body 11 is arranged in the moving path of the mold B2, and the side has a cavity opening toward the mold B2 for accommodating the mold B2 when in use, and changing the shape of the cavity of the mold A body 11 into the shape of the motor housing; its cavity is arranged to match the shape of the motor housing; multiple inserts 12 are installed on the inner side of the cavity of the mold A body 11.

[0039] In this embodiment, the hydraulic rod 5 drives the mold B2 to move toward the inner side of the cavity of the mold A body 11, so that the mold B2 is inserted into the inner side of the mold A body 11 and the cavity of the mold A body 11 is sealed. At the same time, the end of the demolding component 4 is connected to the insert 12 to support the insert 12, and the metal liquid is filled into the inner side of the mold A1 through the feed port 6 and the motor housing is formed on the inner side of the mold A body 11 by cooling. The hydraulic rod 5 drives the mold B2 and the demolding component 4 to reset, and the mold B2 drives the motor housing to move toward the outside of the mold A1. During the movement, the mounting plate 3 limits the position of the demolding component 4 to reset the demolding component 4, and the mold B2 continues to move. When the mold B2 continues to move, the demolding component 4 blocks the motor housing, so that the mold B2 moves from the inside of the motor housing to the outside and separates from the motor housing after the mold B2 is reset.

[0040] Example 2

[0041] like Figure 6 As shown, the present invention proposes a die-casting mold for a new energy vehicle drive motor housing. Compared with the first embodiment, in this embodiment, the mold B2 includes a mold B body 21, a heater 22 and a cover plate 23;

[0042] The cover plate 23 is mounted on the end of the hydraulic rod 5;

[0043] The mold B body 21 is bolted to the side of the cover plate 23, and the end of the cover plate 23 has a groove, wherein the cover plate 23 covers the groove of the mold B body 21;

[0044] The heater 22 is arranged on the inner side of the groove of the heater 22. The wire of the heater 22 extends along the opening of the groove of the heater 22 and on the side of the cover 23 to the outside of the heater 22. It is used to heat the mold B body 21 when the heater 22 is powered on in use. By the principle of thermal expansion and contraction, the motor housing is heated when it is separated from the mold B body 21, so that the separation friction between the mold B body 21 and the motor housing is reduced, thereby improving the shell and mold separation effect.

[0045] Example 3

[0046] like Figure 3-5 As shown, the present invention proposes a die-casting mold for a new energy vehicle drive motor housing. Compared with the first embodiment, in this embodiment, the demoulding assembly 4 includes a connecting rod 41, a push block 42 and a support rod 43;

[0047] The support rod 43 is slidably mounted on the mounting plate 3; its rectangular shape is used to prevent the push block 42 from rotating during use and thus being unable to be installed in the mounting groove of the mold B2;

[0048] The connecting rod 41 is mounted on the end of the support rod 43, and one end thereof passes through the mold B2. When in use, the mold B2 slides on the connecting rod 41, so that the connecting rod 41 drives the push block 42 to separate the shell from the mold B2.

[0049] The push block 42 is installed at one end of the connecting rod 41 and is movably connected to the mold B2. A tapered block is provided on the side for being inserted into the end of the insert 12.

[0050] In an optional embodiment, a retaining ring is extended outwardly and in parallel at the end of the support rod 43 for limiting the moving distance of the support rod 43 by connecting the retaining ring of the support rod 43 to the mounting plate 3 when in use.

[0051] In an optional embodiment, an internal threaded mounting groove is provided at the end of the support rod 43, and a thread is provided on the outer side of the other end of the connecting rod 41. When the connecting rod 41 and the support rod 43 are installed in cooperation, the other end of the connecting rod 41 is accommodated in the internal threaded mounting groove of the support rod 43, and the threaded connection enables the connecting rod 41 to be quickly separated from the mold B2.

[0052] In an optional embodiment, a half-moon wheel is provided at the end of the push block 42, and a mounting groove is provided on the side of the mold B2. When the mold A1 and the mold B2 are in a mating installation state, the half-moon wheel of the push block 42 is accommodated inside the mounting groove of the mold B2, wherein the size of the half-moon wheel is larger than the size of the motor housing connection hole, and the half-moon wheel is arranged away from the center of the mold B2, and is used to contact the end of the motor when the insert 12 casts the motor housing mounting connection hole, and to block the housing from the mold B2 under the contraction of the hydraulic rod 5 and the blocking of the mounting plate 3.

[0053] In summary, when the present invention is in use, the hydraulic rod 5 drives the mold B2 to move toward the inner side of the cavity of the mold A body 11, so that the mold B2 is inserted into the inner side of the mold A body 11 and the cavity of the mold A body 11 is sealed. At the same time, the mold B2 drives the end of the demoulding component 4 to connect with the insert 12, supports the insert 12 and seals the connection rod 41 and the mold B2. The metal liquid is filled into the inner side of the mold A1 through the feed port 6, so that the mold A body 11 and the mold B body 21 cooperate to form the cavity into the shape of the motor housing and form it through cooling. The hydraulic rod 5 drives the mold B2 and the demoulding component 4 to the mold A body 1 1, and at the same time, the motor housing is wrapped on the mold B2 due to cooling, and is driven by the mold B2 to move to the outside of the mold A1, and during the movement, the mounting plate 3 limits the position of the support rod 43, so that the position of the push block 42 is fixed, and the mold B2 continues to move. When the mold B2 continues to move, the heater 22 starts to heat the mold B body 21, so that the temperature of the motor housing increases. At the same time, the semi-moon wheel of the push block 42 blocks the motor housing, so that the mold B2 moves from the inside of the motor housing to the outside, and is separated from the motor housing after the mold B2 is reset, so that the motor housing is easy to separate and the situation that it cannot be separated is avoided.

[0054] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
