A vertical block 25 is installed on the top of the base 1. The height of the vertical block 25 is the same as the height of the support blocks 21. Columns 24 are evenly connected to the top of the base 1. The top of the columns 24 extends into the interior of the middle mold assembly 3. The two support blocks 21, the two top blocks 22, and the vertical blocks 25 cooperate to limit the position of the middle mold assembly 3. The I-shaped plates 23 and the columns 24 cooperate to support and guide the middle mold assembly 3. The number of I-shaped plates 23 can be placed or removed according to the actual situation to adjust the distance between the lower mold assembly 2 and the middle mold assembly 3.

[0036] The middle mold assembly 3 includes a middle module 31, which is located on top of two support blocks 21. The top of the column 24 extends into the interior of the middle module 31. A boss 32 is installed on one side of the top of the middle module 31. The top of the boss 32 is provided with an arc-shaped part. A first notch 33 is opened on the outer wall of the boss 32. The top of the first notch 33 extends to the position of the arc-shaped part of the boss 32. The middle module 31 is mainly a load-bearing module, that is, the middle module 31 is a sandwich between the lower mold assembly 2 and the upper mold assembly 4, mainly used to separate the lower mold assembly 2 and the upper mold assembly 4.

[0038] The feeding assembly 7 includes a feeding pipe 71, which is located at the top of the upper module 41. The bottom of the feeding pipe 71 extends into the interior of the upper placement groove 42. A second notch 72 is provided at the bottom end of the feeding pipe 71. The bottom end of the feeding pipe 71 is sleeved on the outer wall of the boss 32. The first notch 33 and the second notch 72 are connected. The upper mold assembly 4 is located above the middle mold assembly 3, and the feeding assembly 7 is installed on the upper module 41. Therefore, when the upper mold assembly 4 and the middle mold assembly 3 are closed, the upper module 41 is attached to the middle module 31, and the bottom end of the feeding pipe 71 is connected to the arc-shaped part of the boss 32. At the same time, the first notch 33 is connected to the second notch 72, so that the molten metal can be fed through the top end of the feeding pipe 71, flow along the extension direction of the feeding pipe 71, and then flow out through the positions of the first notch 33 and the second notch 72.

[0039] The molding component 5 includes a lower placement groove 51, which is located in the middle of the top surface of the middle module 31. A lower molding mold 52 is installed inside the lower placement groove 51, and an upper molding mold 53 is installed inside the upper placement groove 42.

When the upper mold component 4 and the middle mold component 3 are closed, the lower molding mold 52 and the upper molding mold 53 merge, and a cavity is formed between the lower molding mold 52 and the upper molding mold 53. The molten metal flowing out from the first notch 33 and the second notch 72 continuously flows into the cavity. When the amount of molten metal flowing in reaches the target, the solution accumulates in the feed pipe 71.

[0040] like Figure 7 As shown, the molten metal in the lower mold 52 and the upper mold 53 will solidify to form product 54;

[0041] The lower placement groove 51 is equipped with an ejector pin 55. The bottom of the lower forming mold 52 is provided with an ejector pin insertion hole, which corresponds to the ejector pin 55. The top end of the ejector pin 55 passes through the ejector pin insertion hole and extends into the lower forming mold 52. The ejector pin 55 extends into the lower forming mold 52 through the ejector pin insertion hole. When the product 54 is formed, holes of various diameters are formed at different positions of the product 54 in one go according to the requirements.

[0042] The positioning component 6 includes a first positioning block 61 and a second positioning block 62. The first positioning block 61 is embedded in the top of the middle module 31, and the second positioning block 62 is embedded in the bottom of the upper module 41. The first positioning block 61 and the second positioning block 62 are in contact with each other. The top of the first positioning block 61 has a groove 63, and the bottom of the second positioning block 62 has an insert block 65. The insert block 65 is inserted into the inside of the groove 63. The inside of the groove 63 has evenly distributed positioning grooves 64. The bottom of the insert block 65 has evenly distributed locking blocks 66. The locking blocks 66 are inserted into the inside of the positioning grooves 64. When the upper mold component 4 and the middle mold component 3 are closed, the upper mold component 4 drives the corresponding second positioning block 62 to fit against the surface of the first positioning block 61, and the insert block 65 is inserted into the inside of the groove 63.

[0043] The inner walls of the groove 63 are all set as inclined surfaces with a certain slope. The side wall of the insert block 65 slides into the groove 63 along the inclined surface of the groove 63. At the same time, the locking block 66 is inserted into the positioning groove 64, thereby avoiding the situation where the second positioning block 62 and the first positioning block 61 are misaligned in the horizontal direction.

[0044] The buffer assembly 8 includes a first buffer hole 81 and a first pagoda-shaped insert 83. The first buffer hole 81 is opened at the top of the I-shaped plate 23, and the first pagoda-shaped insert 83 is installed at the bottom of the middle module 31. The bottom end of the first pagoda-shaped insert 83 extends into the interior of the first buffer hole 81. The bottom four corners of the upper module 41 are evenly connected with second pagoda-shaped inserts 85. The bottom of the middle module 31 is provided with a second buffer hole 84, and the second pagoda-shaped insert 85 is inserted into the interior of the second buffer hole 84. The top of the two support blocks 21 is provided with an air passage 82, which corresponds to the second buffer hole 84. The bottom of the second buffer hole 84 fits into the air passage 82. The first pagoda-shaped insert 83 corresponds to the first buffer hole 81, and the bottom end of the first pagoda-shaped insert 83 is inserted into the first buffer hole 81, thereby ensuring the connection stability between the middle module 31 and the I-shaped plate 23.

[0045] The second pagoda insert 85 corresponds to the second buffer hole 84. When the upper mold assembly 4 and the middle mold assembly 3 are closed, the upper mold assembly 4 drives the second pagoda insert 85 to be inserted into the second buffer hole 84. The gas in the second buffer hole 84 is discharged through the air passage 82, which facilitates the insertion and removal of the second pagoda insert 85. If the gas cannot be discharged, negative pressure is easily generated in the second buffer hole 84, which affects the insertion and removal of the second pagoda insert 85 and is prone to wear.

[0046] A molding process for the housing of a new energy vehicle motor and electronic control unit, using the aforementioned molding die for the housing of a new energy vehicle motor and electronic control unit, comprises the following steps:

[0047] Step 1: The staff connects the upper mold assembly 4 to the external driving device. The external driving device drives the upper mold assembly 4 to move down as a whole. The upper mold assembly 4 and the middle mold assembly 3 complete the mold closing. At the same time, the upper mold assembly 4 drives the upper forming mold 53 to fit with the lower forming mold 52. The lower forming mold 52 and the upper forming mold 53 cooperate to form a cavity.

[0048] Step 2: When the upper mold assembly 4 and the middle mold assembly 3 are closed, the upper mold assembly 4 first drives the second pagoda insert rod 85 to be inserted into the second buffer hole 84. The gas in the second buffer hole 84 is discharged through the air passage 82, and the bottom end of the first pagoda insert rod 83 is inserted into the first buffer hole 81.

[0049] Step 3: The upper mold assembly 4 drives the second positioning block 62 to fit against the top of the first positioning block 61, and the insert block 65 is inserted into the inside of the groove 63. The insert block 65 drives the locking block 66 to slide into the inside of the positioning groove 64 for limiting.

[0050] Step 4: The molten metal flows into the cavity through the feed pipe 71, the second notch 72 and the first notch 33 and accumulates. The molten metal cools and solidifies in the cavity. After the motor and electronic control housing is die-cast, the external drive equipment drives the upper mold assembly 4 to move upward as a whole to complete the mold opening.

[0051] Step 5: After the upper mold assembly 4 and the middle mold assembly 3 are opened, the staff can remove the die-cast motor and electrical control housing.

[0052] Specifically, the staff connects the upper mold assembly 4 to the external driving device. The external driving device drives the upper mold assembly 4 to move down as a whole. At this time, the upper mold assembly 4 drives the upper forming mold 53 to squeeze the lower forming mold 52. The upper forming mold 53 and the lower forming mold 52 fit together, and the lower forming mold 52 and the upper forming mold 53 cooperate to form a cavity.

[0053] When the upper mold assembly 4 and the middle mold assembly 3 are closed, the upper mold assembly 4 first drives the second pagoda insert 85 to be inserted into the second buffer hole 84. The gas in the second buffer hole 84 is discharged through the air passage 82, which facilitates the insertion and removal of the second pagoda insert 85. If the gas cannot be discharged, negative pressure is easily generated in the second buffer hole 84, which affects the insertion and removal of the second pagoda insert 85 and is prone to wear. The bottom end of the first pagoda insert 83 is inserted into the first buffer hole 81, thereby ensuring the connection stability between the middle module 31 and the I-shaped plate 23.

[0054] The upper mold assembly 4 drives the second positioning block 62 to fit against the top of the first positioning block 61, the insert block 65 is inserted into the inside of the groove 63, and the insert block 65 drives the locking block 66 to slide into the inside of the positioning groove 64 for limiting.

[0055] The molten metal flows into the cavity and accumulates through the feed pipe 71, the second notch 72 and the first notch 33.

[0056] To adjust the feeding speed of the molten metal, an external drive device drives the upper mold assembly 4 to squeeze the middle mold assembly 3. The upper forming mold 53 and the lower forming mold 52 squeeze each other, causing the upper forming mold 53 to squeeze the damping block 43 in the upper placement groove 42. By changing the squeezing force of the forming assembly 5 on the damping block 43, the degree to which the forming assembly 5 is embedded in the upper placement groove 42 is adjusted. At this time, the distance between the upper mold assembly 4 and the middle mold assembly 3 is reduced, that is, the interlocking length of the feed pipe 71 and the boss 32 is adjusted. The flow channel formed by the second notch 72 and the first notch 33 is reduced, thereby changing the feeding speed of the molten metal and preventing the product 54 from sticking to the mold at the feed port position.

[0057] The molten metal cools and solidifies in the cavity. After the motor and electronic control housing is die-cast, the external drive equipment drives the upper mold assembly 4 to move upward as a whole to complete the mold opening. After the upper mold assembly 4 and the middle mold assembly 3 are opened, the workers can remove the die-cast motor and electronic control housing.
