Technical Field

[0001] The present disclosure relates to the technical field of die casting surface treatment, and in particular to a die casting surface treatment mold and new energy automobile parts production equipment. Background Art

[0002] With the increasing application of aluminum alloy die-castings due to their beautiful appearance, light weight and corrosion resistance, how to reduce the manufacturing cost of aluminum alloy die-castings while ensuring their product quality has become a hot research direction. The production cost of aluminum alloy die-castings can be roughly divided into four parts: materials, die-casting, machining and surface treatment; reasonable mold design can reduce the production process of aluminum alloy die-castings and thus reduce production costs.

[0003] For example, a Chinese patent with application number CN202320147754.4 discloses a polishing device for surface treatment of aluminum alloy die-castings, including a first mounting rod, which is arranged on one side below a crossbeam and is rotatably connected to the crossbeam, and two clamping plates are provided at the lower end of the first mounting rod so as to be openable and closable; a movable seat is arranged at the lower part of the crossbeam, a second mounting rod is provided below the movable seat, a mounting plate is provided inside the lower part of the second mounting rod, and a plurality of steel brushes are rotatably provided on the mounting plate.

[0004] The above-mentioned aluminum alloy die-casting surface treatment grinding device is composed of a die-casting surface grinding device by arranging a crossbeam, a mounting plate, a movable seat and a steel brush, etc., which is used to grind the waste materials such as the weld line on the surface of the die-casting to make the surface of the die-casting smooth and beautiful, and at the same time reduce the labor cost of grinding the die-casting. However, the device cost problem of the above-mentioned aluminum alloy die-casting surface treatment grinding device cannot be ignored.

[0005] Therefore, there is a need for a die casting surface treatment mold and new energy vehicle parts production equipment that does not require the addition of a grinding device and further reduces production costs. Utility Model Content

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a die casting surface treatment mold and new energy vehicle parts production equipment that do not require the addition of a grinding device and further reduce production costs.

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0008] A die-casting surface treatment mold comprises a fixed mold, a core-pulling mold and a movable mold, wherein the movable mold is movably arranged relative to the fixed mold, a core-pulling cavity is provided between the movable mold and the fixed mold, and the core-pulling mold is movably arranged in the core-pulling cavity, the fixed mold is provided with a first accommodating cavity, the core-pulling mold is provided with a guide channel, a second accommodating cavity is provided at the connection between the fixed mold and the movable mold, so that the die-casting is formed in the second accommodating cavity, the first accommodating cavity, the guide channel and the second accommodating cavity are connected in sequence; an overflow port is provided at the connection between the guide channel and the second accommodating cavity, the machined surface of the die-casting is flush with the overflow port, the core-pulling mold is convexly provided with an extrusion convex point, and the extrusion convex point is located in the guide channel so as to form a fracture groove on the slag bag of the die-casting.

[0009] In one of the embodiments, the distance between the overflow port and the guide channel adjacent to the fixed mold is 0.3-0.8 cm.

[0010] In one embodiment, the depth of the fracture groove is 0.3-0.8 cm.

[0011] In one embodiment, the extrusion protrusion is a circular protrusion.

[0012] In one of the embodiments, the height of the overflow port is greater than the distance between the overflow port and a side of the guide channel adjacent to the fixed mold.

[0013] In one embodiment, the height of the overflow port is 0.8-1.4 cm.

[0014] In one embodiment, the width of the overflow port is smaller than the width of the machined surface of the die casting.

[0015] The present application also provides a new energy automobile parts production equipment, including the die-casting surface treatment mold of any of the above embodiments.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] The above-mentioned die-casting surface treatment mold has a first accommodating chamber in the fixed mold, a guide channel in the core-pulling mold, and a second accommodating chamber at the connection between the fixed mold and the movable mold. The first accommodating chamber, the guide channel and the second accommodating chamber are connected in sequence. When injecting liquid, the aluminum alloy casting liquid first enters the first accommodating chamber, and enters the second accommodating chamber from the first accommodating chamber through the guide channel for die-casting. Furthermore, since an overflow port is provided at the connection point between the guide channel and the second accommodating chamber, the machined surface of the die-casting is flush with the overflow port, and the extrusion protrusion squeezes the guide channel to form a fracture groove, so that when the core is pulled, the molten casting waste in the guide channel is broken at the fracture groove, thereby avoiding the molten casting waste remaining on the surface of the die-casting for too long, and the molten casting waste is formed above the machined surface of the die-casting and will not collapse into the die-casting body. In the subsequent die-casting surface processing steps, the molten casting waste located above the machined surface can be removed synchronously, so there is no need to add an additional grinding device or use a manually operated file to file the surface molten casting waste, thereby saving the process of grinding the surface of the die-casting and saving production costs. In addition, since there is no need to grind or file the die-casting, the surface of the die-casting has no grinding or filing marks, and the appearance of the die-casting product is more beautiful.

[0024] The present disclosure provides a die casting surface treatment mold, comprising a fixed mold, a core-pulling mold and a movable mold, wherein the movable mold is movably arranged relative to the fixed mold, a core-pulling cavity is disposed between the movable mold and the fixed mold, and the core-pulling mold is movably arranged in the core-pulling cavity, the fixed mold is provided with a first accommodating cavity, the core-pulling mold is provided with a guide channel, a second accommodating cavity is provided at the connection between the fixed mold and the movable mold, so that the die casting is formed in the second accommodating cavity, the first accommodating cavity, the guide channel and the second accommodating cavity are connected in sequence; an overflow port is provided at the connection between the guide channel and the second accommodating cavity, the machined surface of the die casting is flush with the overflow port, the core-pulling mold is convexly provided with an extrusion convex point, and the extrusion convex point is located in the guide channel, so as to form a fracture groove on the slag bag of the die casting.

[0025] The above-mentioned die-casting surface treatment mold has a first accommodating chamber in the fixed mold, a guide channel in the core-pulling mold, and a second accommodating chamber at the connection between the fixed mold and the movable mold. The first accommodating chamber, the guide channel and the second accommodating chamber are connected in sequence. When injecting liquid, the aluminum alloy casting liquid first enters the first accommodating chamber, and enters the second accommodating chamber from the first accommodating chamber through the guide channel for die-casting. Furthermore, since an overflow port is provided at the connection between the guide channel and the second accommodating chamber, the machined surface of the die-casting is flush with the overflow port, and the extrusion protrusion squeezes the guide channel to form a fracture groove, so that when the core is pulled, the molten casting waste in the guide channel is broken at the fracture groove, thereby avoiding the molten casting waste remaining on the surface of the die-casting for too long, and the molten casting waste is formed above the machined surface of the die-casting and will not collapse into the die-casting body.

In addition, since there is no need to grind or file the die-casting, the surface of the die-casting has no grinding or filing marks, and the appearance of the die-casting product is more beautiful.

[0026] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0027] like Figure 1 and Figure 2 As shown, a die casting surface treatment mold 10 of an embodiment includes a fixed mold 100, a core-pulling mold 200 and a movable mold 300, wherein the movable mold 300 is movably arranged relative to the fixed mold 100, a core-pulling cavity 202 is provided between the movable mold 300 and the fixed mold 100, and the core-pulling mold 200 is movably arranged in the core-pulling cavity 202, the fixed mold 100 is provided with a first accommodating cavity 101, the core-pulling mold 200 is provided with a guide channel 201, and a second accommodating cavity 301 is provided at the connection between the fixed mold 100 and the movable mold 300, so that the die casting 10a is formed in the second accommodating cavity 301, and the first accommodating cavity 101, the guide channel 201 and the second accommodating cavity 301 are connected in sequence;

[0028] An overflow port 400 is provided at the connection between the guide channel 201 and the second accommodating chamber 301, and the machined surface of the die casting 10a is flush with the overflow port 400. The core pulling mold 200 is provided with an extrusion protrusion 210, and the extrusion protrusion 210 is located in the guide channel 201 to form a fracture groove 2001 on the slag bag of the die casting 10a.

[0029] In this embodiment, the first accommodating chamber 101, the guide channel 201 and the second accommodating chamber 301 are connected in sequence. When the liquid is injected, the aluminum alloy casting liquid first enters the first accommodating chamber 101, and then enters the second accommodating chamber 301 from the first accommodating chamber 101 through the guide channel 201 for die casting. Furthermore, an overflow port 400 is provided at the connection between the guide channel 201 and the second accommodating chamber 301, and the processing surface of the die casting 10a is fitted with the overflow port 400, so that the casting liquid waste is formed above the processing surface of the die casting 10a, and will not collapse into the body of the die casting 10a, that is, the casting liquid waste on the surface of the die casting 10a is all formed above the surface of the die casting 10a, waiting to be removed synchronously in the subsequent surface processing step of the die casting 10a. The core-pulling die 200 is provided with an extrusion protrusion 210, which squeezes the guide channel 201 to form a fracture groove 2001, that is, when the core is pulled, the casting waste in the guide channel 201 is broken at the fracture groove 2001, thereby preventing the casting waste from remaining on the surface of the die-casting 10a for too long.

[0030] In the above-mentioned die casting surface treatment mold 10, the fixed mold 100 is provided with a first accommodating chamber 101, the core-pulling mold 200 is provided with a guide channel 201, and the connection between the fixed mold 100 and the movable mold 300 is provided with a second accommodating chamber 301. The first accommodating chamber 101, the guide channel 201 and the second accommodating chamber 301 are connected in sequence. When injecting liquid, the aluminum alloy casting liquid first enters the first accommodating chamber 101, and enters the second accommodating chamber 301 from the first accommodating chamber 101 through the guide channel 201 for die casting. Furthermore, since the overflow port 400 is provided at the connection between the guide channel 201 and the second accommodating chamber 301, the machined surface of the die casting 10a is flush with the overflow port 400, and the extrusion convex point 210 squeezes the guide channel 201 to form a fracture groove 2001, so that when the core is pulled, the casting waste in the guide channel 201 is broken at the fracture groove 2001, thereby preventing the casting waste from remaining too long on the surface of the die casting 10a, and the casting waste is formed above the machined surface of the die casting 10a, and will not The molten metal is broken into the body of the die-casting 10a. In the subsequent surface processing step of the die-casting 10a, the molten casting waste located above the processing surface can be removed simultaneously. Therefore, there is no need to add an additional grinding device or use a manually operated file to file the surface molten casting waste, thereby saving the process of grinding the surface of the die-casting 10a and saving production costs. In addition, since there is no need to grind or file the die-casting 10a, the surface of the die-casting 10a has no grinding or filing marks, and the appearance of the die-casting 10a product is more beautiful.

[0031] like Figure 1 and Figure 2As shown, in one embodiment, the distance between the overflow port 400 and the guide channel 201 adjacent to the side of the fixed mold 100 is 0.3-0.8cm. In this embodiment, the distance between the overflow port 400 and the guide channel 201 adjacent to the side of the fixed mold 100 is 0.5cm, that is, the position of the fixed mold 100 corresponding to the overflow port 400 is relatively raised by 0.5cm, so that the waste of the aluminum alloy casting liquid is formed above the surface of the die casting 10a, and will not collapse into the body of the die casting 10a, which is convenient for the subsequent die casting 10a surface processing step to synchronously remove the waste casting liquid on the surface of the die casting 10a. It can be understood that if the distance is too small, it is easy to cause the waste casting liquid to collapse into the body of the die casting 10a, and it cannot be removed in the subsequent steps. If the distance is too large, it causes the aluminum alloy casting liquid to gather in large quantities on the surface of the die casting 10a, which not only wastes raw materials but also makes it difficult to remove in the subsequent steps.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the depth of the fracture groove 2001 is 0.3-0.8cm. In this embodiment, the depth of the fracture groove 2001 is 0.5cm, that is, the core-pulling mold 200 corresponds to the extrusion of the flow channel 201 by 0.5cm, so that the aluminum alloy casting liquid in the flow channel 201 is broken at the fracture groove 2001 when the core is pulled, and the casting liquid waste is prevented from remaining too long on the surface of the die casting 10a. It can be understood that if the depth of the fracture groove 2001 is too small, it is easy to cause the aluminum alloy casting liquid in the flow channel to be difficult to break at the fracture groove 2001 when the core is pulled, and the casting liquid waste remains too long on the surface of the die casting 10a, which is inconvenient to remove the waste in the subsequent process. If the depth of the fracture groove 2001 is too large, the flow rate of the aluminum alloy casting liquid is slowed down during the injection, and the molding time of the die casting 10a is prolonged, which reduces the working efficiency of the mold.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the extrusion protrusion 210 is a circular protrusion. In this embodiment, the extrusion protrusion 210 is a circular protrusion. It can be understood that the shape of the fracture groove 2001 formed by the circular extrusion protrusion 210 extruding the guide channel 201 is also circular. The circular fracture groove 2001 ensures the normal circulation of the aluminum alloy casting liquid in the guide channel 201 to prevent the casting liquid from being blocked.

[0034] like Figure 1 and Figure 2As shown, in one embodiment, the height of the overflow port 400 is greater than the distance between the overflow port 400 and the guide channel 201 adjacent to the fixed mold 100, and the height of the overflow port 400 is 0.8-1.4 cm. In this embodiment, the height of the overflow port 400 is 1.0 cm, which is greater than the distance between the overflow port 400 and the guide channel 201 adjacent to the fixed mold 100 by 0.5 cm. It can be understood that if the overflow port 400 is too low, the waste of the aluminum alloy casting liquid is easy to collapse into the body of the die casting 10a, and it is difficult to remove it later. If the overflow port 400 is too high, a large amount of aluminum alloy casting liquid is retained on the surface of the die casting 10a, causing waste.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the width of the overflow port 400 is smaller than the width of the machined surface of the die casting 10a. In this embodiment, the width of the overflow port 400 is smaller than the width of the machined surface of the die casting 10a, that is, the overflow port 400 is located on one side of the machined surface of the die casting 10a, and the other side of the machined surface of the die casting 10a is in contact with the core-pulling die 200, so that when the core is pulled, the aluminum alloy casting waste is generated on one side of the machined surface of the die casting 10a, which is convenient for synchronously removing the casting waste in the subsequent surface processing process of the die casting 10a.

[0036] The present application also provides a new energy automobile parts production equipment, including the die casting surface treatment mold 10 of any of the above embodiments.

[0037] Compared with the prior art, the present invention has at least the following advantages:

[0038] In the above-mentioned die casting surface treatment mold 10, the fixed mold 100 is provided with a first accommodating chamber 101, the core-pulling mold 200 is provided with a guide channel 201, and the connection between the fixed mold 100 and the movable mold 300 is provided with a second accommodating chamber 301. The first accommodating chamber 101, the guide channel 201 and the second accommodating chamber 301 are connected in sequence. When injecting liquid, the aluminum alloy casting liquid first enters the first accommodating chamber 101, and enters the second accommodating chamber 301 from the first accommodating chamber 101 through the guide channel 201 for die casting. Furthermore, since the overflow port 400 is provided at the connection between the guide channel 201 and the second accommodating cavity 301, the machined surface of the die casting 10a is flush with the overflow port 400, and the core pulling die 200 is provided with an extrusion convex point 210, and the extrusion convex point 210 squeezes the guide channel 201 to form a fracture groove 2001, so that when the core is pulled, the casting waste in the guide channel 201 is broken at the fracture groove 2001, thereby preventing the casting waste from remaining too long on the surface of the die casting 10a, and the casting waste is formed on the die casting 10a. The waste casting liquid above the processed surface will not collapse into the body of the die-casting 10a. In the subsequent surface processing steps of the die-casting 10a, the waste casting liquid above the processed surface can be removed simultaneously. Therefore, there is no need to add an additional grinding device or use a manually operated file to file the surface waste casting liquid, thereby saving the process of grinding the surface of the die-casting 10a and saving production costs. In addition, since there is no need to grind or file the die-casting 10a, there is no trace of grinding or filing on the surface of the die-casting 10a, and the appearance of the die-casting 10a product is more beautiful.

[0039] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
