Description

Technical Field

[0001] The utility model relates to a magnesium alloy die-casting die, in particular to a novel magnesium alloy lightweight product die-casting die. Background Art

[0002] With the continuous development of technology, metal die-casting molds have been widely used in industrial production. Generally speaking, die-casting molds work at relatively high working temperatures. When working, molten metal liquid needs to be injected into the mold cavity at high pressure and high speed, which will inevitably cause the entire mold to heat up rapidly. For example, the temperature of the magnesium alloy solution is as high as 630-650°C. The high-speed impact of the high-temperature metal flow during the magnesium alloy die-casting mold requires careful operation in subsequent operations, which brings great inconvenience to production efficiency. When the staff comes into contact with it, it is inevitable that the staff will suffer burns and other damage to their bodies. For this reason, a magnesium alloy die-casting mold is provided.

[0003] Chinese patent CN208600693U discloses a magnesium alloy die-casting mold. The device is fixedly connected to the upper mold through the first hydraulic rod and the second hydraulic rod at the top of the first hydraulic cylinder and the second hydraulic cylinder. The opening and closing of the die-casting mold are automatically controlled by a control switch, thereby avoiding burns caused by workers accidentally touching the mold and ensuring the safety of workers during operation. By connecting the water pump output pipe to one side of the water storage pipe and the water injection pipe at the input end to the other side of the water storage pipe, water circulation can be formed inside the die-casting mold. Water is introduced into the water source through the water injection waterproof hole, and coolant is added through the cooling water injection hole to quickly cool the inside of the die-casting mold.

[0029] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1 and Figure 2 : A new type of magnesium alloy lightweight product die-casting mold, the die-casting mold includes: a first frame 1, a second frame 2, a first mold 3, a second mold 4 and a driving assembly 5, the first frame 1 and the second frame 2 are arranged opposite to each other, the first mold 3 is arranged on the side of the first frame 1 close to the second frame 2, and the second mold 4 is slidably arranged on the second frame 2 along the direction close to or away from the first mold 3 through the driving assembly 5; wherein, the driving assembly 5 includes: a first linear drive 501 and a connecting rod assembly 502 with a hinged structure in the middle, the first linear drive 501 is arranged on one side of the second frame 2, the middle hinged end of the connecting rod assembly 502 is also hinged to the output end of the first linear drive 501, one end of the connecting rod assembly 502 is hinged to the side wall of the second frame 2, and the other end is hinged to the second mold 4, when the first linear drive 501 is telescopically driven, it can drive the second mold 4 to slide through the connecting rod assembly 502.

[0031] The present application starts the first linear drive 501 to drive the second mold 4 to slide in the direction close to or away from the first mold 3 through the connecting rod assembly 502, thereby adjusting the opening and closing distance of the die-casting mold, wherein the connecting rod assembly 502 acts as a force-multiplying mechanism, which is a mechanism that sacrifices stroke to increase the force, thereby increasing the pressure that the first linear drive 501 can apply and improving product quality.

[0032] Reference Figure 3 : The connecting rod assembly 502 includes: a first connecting rod 50201, a second connecting rod 50202 and a third connecting rod 50203. One end of each of the three connecting rods is hinged together through the same hinge axis, and the other end of the first connecting rod 50201 is hinged to the side wall of the second frame 2, the other end of the second connecting rod 50202 is hinged to the output end of the first linear drive 501, and the other end of the third connecting rod 50203 is hinged to the side of the second mold 4 away from the first mold 3.

[0033] In this application, by activating the first linear actuator 501, the second connecting rod 50202 drives the first connecting rod 50201 and the third connecting rod 50203 to bend, thereby causing the second mold 4 to slide away from the first mold 3 and adjusting the mold opening and closing distance. At the same time, the sum of the length of the third connecting rod 50203 and the length of the first connecting rod 50201 is greater than the maximum distance between the side wall of the second mold 4 and the side wall of the second frame 2, thereby preventing the first linear actuator 501 from extending too far and causing the fit between the second mold 4 and the first mold 3 to loosen. With this design, the connecting rod assembly 502 can effectively transmit the driving force.

[0034] Reference Figure 3 : The second frame 2 is provided with limiting slide rails 201 on the two opposite side walls, and the second mold 4 is provided with limiting sliders 401 adapted to the limiting slide rails 201 on the two opposite side walls. The second mold 4 can be slidably assembled on the corresponding limiting slide rails 201 through the limiting sliders 401.

[0035] This design of the present application enables the second mold 4 to be slidably assembled along a fixed track, ensuring accurate alignment and stability of the mold, which is beneficial to improving the molding quality and production efficiency of the product.

[0036] Reference Figure 4 : The first mold 3 and the second mold 4 are respectively provided with a front mold core 301 and a rear mold core 402 that adapt to each other on one side close to each other.

[0037] The front mold core 301 and the rear mold core 402 of the present application play a role in positioning and supporting the mold when it is closed, which can effectively control the closing position of the mold and maintain the stability of the overall structure of the mold. Their mutual adaptation design can ensure the precise alignment and coordinated movement of the mold during operation.

A glue squeezing component 303 is provided on one side of the pouring port 30201, and the output end of the glue squeezing component 303 is adapted to the pouring pipe 302, and can squeeze the raw material from the pouring pipe 302 to the interior of the front mold core 301.

[0039] In this application, the raw material is injected and filled through the pouring port 30201, and then the raw material in the pouring pipe 302 is squeezed into the interior of the front mold core 301 and the rear mold core 402 through the glue extrusion component 303 through the glue injection port 30101, and then left to cool, thereby realizing the shaping of the workpiece. The setting of the glue injection port 30101 can ensure that the raw material can be squeezed into the interior of the front mold core 301 and the rear mold core 402 little by little by the glue extrusion component 303, thereby accelerating the cooling efficiency of the raw material.

[0040] Reference Figure 5 : The glue squeezing component 303 includes: a second linear drive 30301 and a glue squeezing rod 30302 coaxially arranged at the output end of the second linear drive 30301, the second linear drive 30301 is arranged on one side of the pouring port 30201, and its output shaft is coaxially arranged with the pouring pipe 302, and the glue squeezing rod 30302 is adapted to the pouring pipe 302.

[0041] This application uses a second linear drive 30301 to provide extrusion force, thereby pushing the raw material to the injection port 30101, and the extrusion rod 30302 is adapted to the casting pipe 302 to ensure that the raw material can be smoothly extruded into the mold, thereby realizing the molding of the product.

[0042] Reference Figure 6 and Figure 7 : A plurality of ejection holes 40201 are horizontally provided on the rear mold core 402, and a third linear drive 403 is provided on the second mold 4, and its output shaft is provided with a plurality of ejection rods 404 corresponding to each ejection hole 40201.

[0043] After the workpiece is formed, the front mold core 301 and the rear mold core 402 are separated, and then the third linear drive 403 is started to drive the ejection rod 404 to eject the workpiece, thereby improving production efficiency and operational convenience.

[0044] When the device provided by the present invention is in use, the present application activates the first linear drive 501 to drive the second mold 4 to slide in the direction close to or away from the first mold 3 through the connecting rod assembly 502, thereby adjusting the opening and closing distance of the die-casting mold, wherein the connecting rod assembly 502 acts as a force-multiplying mechanism, which is a mechanism that sacrifices stroke to increase the force, thereby increasing the pressure that the first linear drive 501 can apply and improving product quality.
