[0024] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
[0025] The utility model provides a powertrain rear suspension bracket assembly, such as Figure 1 As shown, the powertrain rear suspension bracket assembly 100 is a triangular fork view after being projected in one direction, and is a slanted view after being projected in another direction, and one direction is perpendicular to the other direction; the interior of the powertrain rear suspension bracket assembly 100 is connected by reinforcing ribs 110 and circular holes 120 of different shapes, and the largest side surfaces 130 and 140 on both sides are connected into one body by a cylindrical pair 150 and an arc-shaped reinforcing rib 160.
[0026] Specifically, the powertrain rear mount bracket assembly 100 in the present utility model is made of A356 aluminum alloy by using the liquid die forging process. Using A356 aluminum alloy to replace the stamping and welding parts realizes the lightweight of the powertrain rear mount bracket, reduces the overall weight of the chassis system, has a lower cost, and reduces the energy consumption ratio per unit mileage of the whole vehicle.
[0027] The liquid die forging process is a new type of casting process with the advantages of high quality, high efficiency, energy saving, low consumption, wide adaptability, etc. This process is to use external force to make the molten metal solidify and flow in a high-strength mold, and then forcefully eliminate the shrinkage cavity or shrinkage porosity defects caused by solidification shrinkage, and even plastic deformation occurs. The present utility model adopts this advanced casting process, and its quality and performance have been greatly improved.
[0028] On the above basis, this embodiment also provides a manufacturing device for the powertrain rear mount bracket assembly, which is used to manufacture the above-mentioned powertrain rear mount bracket assembly.
[0029] Please refer to Figure 2 , the manufacturing device for the powertrain rear mount bracket assembly includes a handle part 210 and a mold body 220 for the powertrain rear mount bracket assembly fixed on the top of the handle part 210.
[0030] The handle part 210 is in a shell shape and is a cylindrical structure; it includes a liquid injection port 211, and the liquid injection port 211 is located at the end of the handle part 210.
[0031] The interiors of both the handle part 210 and the mold body 220 are cavities. The number of cavities 221 in the mold body 220 is two, so that a set of mold body 200 can form two powertrain rear mount bracket assemblies 100 at one time, improving production efficiency and reducing manufacturing costs.
[0032] The cavities 221 in the handle part 210 and the mold body 220 are connected through a runner 230 with a cavity inside. The runner 230 includes an injection end 231 and an output end 232. The injection end 231 is connected to the handle part 210, and the number of output ends 232 is two. The top sides of the two output ends 232 are respectively connected to the cavity 221 of a mold body 220. The cross-section of the cavity of the runner 230 is rectangular, and both output ends 232 are cylindrical output ends. The handle part 210 and the multi-runner are designed into a classic thick and large multi-Y structure. The multi-runner and the thick handle part can compensate for the defects caused inside the product, and the aluminum liquid can flow better into the inside of the mold, facilitating molding.
[0033] On the parting surface of the mold body 220 opposite to the material handle portion 210, at least one slag pocket 240 (the aforementioned first slag pocket) and at least one exhaust channel groove 250 (the aforementioned first exhaust channel groove) are provided. The interiors of both the slag pocket 240 and the exhaust channel groove 250 are cavities. The cavity in any one slag pocket 240 communicates with the cavity 221 in the mold body 220 and is also connected to the exhaust channel groove 250 through the cavity of the flow channel.
[0034] At least one slag pocket 260 (the aforementioned second slag pocket) and at least one exhaust channel groove 270 (the aforementioned second exhaust channel groove) are provided at both positions of the mold body 220 opposite to the material handle portion 210. The cavity in the slag pocket 260 communicates with the cavity 221 in the mold body 220 and is also connected to the exhaust channel groove 270 through the cavity of the flow channel.
[0035] The cavities in any one slag pocket 240 and any one slag pocket 260 and the cavity 221 in the mold body 220 form a quadrilateral structure. The functions of the multiple slag pockets 240 and 260 are to facilitate better removal of air at the mold parting line position and residual debris during production impurity removal, and at the same time, to balance the temperature of the mold, so as to avoid serious flash and burrs on the subsequent product, and reduce the defects inside the product.
[0036] A recovery pocket 280 is provided in the mold body 220. The recovery pocket 280 is connected to the exhaust channel groove through the cavity of the flow channel. In this embodiment, the entire mold body 220 is made of high-strength metal, so that the liquid metal fills the inside of the mold body under pressure, ensuring a relatively high surface quality of the power-train rear mount bracket assembly.
[0037] The present utility model also provides a method for using the above-mentioned manufacturing equipment for the power-train rear mount bracket assembly:
[0038] During operation, molten aluminum is poured into the injection port 211 of the material handle portion 210, and the power-train rear mount bracket assembly is filled through the cavity 221 in the mold body 220 that matches the outer shape of the power-train rear mount bracket assembly. Cold materials such as slag are collected at the front end and intersection of the molten aluminum. When the molten aluminum is filled to 90%, a pressure of 80 - 100 MPa is applied to enable the molten aluminum to solidify sequentially under high pressure, thereby obtaining a power-train rear mount bracket assembly with excellent performance.
