Technical Field
[0001] The utility model relates to the technical field of die-casting processing, in particular to a double-stage die-casting barrel. Background Art
[0002] The die-casting machine includes an injection cavity and a die-casting feed barrel. The injection cavity is located in the die-casting feed barrel, and the die-casting feed barrel extends into the product cavity. The molten metal enters the product cavity through the injection cavity to complete the casting.
[0003] In the prior art, most factories still use traditional die-casting feed barrels. Generally, metal residues are prone to appear inside the traditional die-casting feed barrel after a long period of use, which will affect the quality of the subsequently processed products. Since this type of die-casting feed barrel is an integral whole, it is impossible to disassemble and replace some parts of the die-casting feed barrel. Therefore, the entire die-casting feed barrel needs to be replaced, which also increases the overall processing cost. Utility Model Content
[0004] The utility model aims to address the deficiencies in the prior art and to propose a two-stage die-casting feed barrel, which is used to solve the technical problem that parts of the die-casting feed barrel are damaged during operation, and some parts of the die-casting feed barrel cannot be disassembled and replaced, so the entire die-casting feed barrel needs to be replaced, which increases the overall processing cost.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A two-stage die-casting barrel comprises a first shot barrel and a second shot barrel, one end of the second shot barrel is detachably mounted on one end of the first shot barrel, a first feed port is provided on a side wall of one end of the second shot barrel, an internal thread is provided on the inner wall of the second shot barrel, a bushing is connected to the internal thread of the second shot barrel, an external thread is provided on the outer wall of the bushing which is screwed to the second shot barrel, a second feed port is provided on the bushing, and the second feed port is communicated with the first feed port, and a first shot barrel is provided on the outer wall of the first shot barrel There are a number of grooves distributed in a ring shape, and a through hole is opened on the side walls of the plurality of grooves. The through hole is located inside the side wall of the first shot cylinder and extends along the length direction of the first shot cylinder to the end face of the first shot cylinder. A number of lock holes are opened on the edge of one side of the second shot cylinder close to the first shot cylinder, and the plurality of through holes and the plurality of lock holes are interconnected, and the inner walls of the through holes and the lock holes are both threaded hole structures; it also includes first bolts, and a number of the first bolts are threadedly connected one by one and pass through the corresponding through holes and lock holes.
[0007] Working principle:
[0008] In actual application, the operator first screws the bushing on the bottom of the second shot cylinder until the first feed port and the second feed port are connected to each other, then respectively passes the first bolt through the through hole on the groove and the lock hole on the second shot cylinder, and screws the first shot cylinder and the second shot cylinder with the first bolt to ensure their tightness, and then the operator injects the molten metal into the first feed port on the second shot cylinder, so that the molten metal passes through the first feed port and the second feed port at the same time and enters the second feed port, and then the operator uses external power to drive the die-casting head into one end of the first shot cylinder until the molten metal is pushed into the die-casting machine for liquid molding.
[0009] After a long period of processing, residual metal liquid will condense on the inner wall of the bushing after cooling. After the metal liquid is cooled and formed, different metal liquid will be added in the next processing, which will cause different metals to be contained in the next metal processing, resulting in unqualified products after die-casting. Therefore, it is only necessary to wait for cooling, unscrew the first bolt, and separate the first shot cylinder and the second shot cylinder. In this way, the residual metal liquid can be replaced in the second shot cylinder, and then the cooled bushing can be rotated out of the second shot cylinder. The second shot cylinder and the bushing with or without utilization value can be replaced respectively in two different ways, which greatly reduces the processing cost.
[0010] The beneficial effects of the utility model are:
[0011] When it is necessary to replace the hardened molten metal remaining in the first shooting cylinder, the second shooting cylinder and the bushing, the operator first removes the entire shooting cylinder, and then checks the shooting chamber in the shooting cylinder. When there is molten metal remaining on the inner wall of the bushing, the bushing can be rotated out of the second shooting cylinder. When there is molten metal remaining on the inner wall of the second shooting cylinder, the first shooting cylinder and the second shooting cylinder are separated. In this way, the cost of replacing parts in the shooting cylinder can be reduced each time molten metal remains in the bushing, the first shooting cylinder or the second shooting cylinder, thereby reducing the processing cost.

DETAILED DESCRIPTION
[0015] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0016] like Figure 1 and Figure 2 As shown, a two-stage die-casting barrel comprises a first shot barrel 1 and a second shot barrel 2, one end of the second shot barrel 2 is detachably mounted on one end of the first shot barrel 1, a first feed port 3 is provided on the side wall of one end of the second shot barrel 2, an internal thread is provided on the inner wall of the second shot barrel 2, a bushing 4 is connected to the internal thread of the second shot barrel, an external thread is provided on the outer wall of the bushing 4 to be screwed to the second shot barrel 2, a second feed port 5 is provided on the bushing 4, and the second feed port 5 is communicated with the first feed port 3, and the first shot barrel 1 is provided on the outer wall There are a plurality of grooves 6 distributed in an annular shape, and a through hole 7 is opened on the side wall of the plurality of grooves 6. The through hole 7 is located inside the side wall of the first shot cylinder 1 and extends along the length direction of the first shot cylinder 1 to the end face of the first shot cylinder 1. A plurality of lock holes 8 are opened on the edge of one side of the second shot cylinder 2 close to the first shot cylinder 1, and the plurality of through holes 7 and the plurality of lock holes 8 are interconnected, and the inner walls of the through holes 7 and the lock holes 8 are both threaded hole structures; it also includes first bolts 9, and a plurality of the first bolts 9 are threadedly connected and penetrated through the corresponding through holes 7 and lock holes 8 one by one.
[0017] In actual applications, residual metal liquid will condense on the inner wall of the bushing 4 after cooling. After the metal liquid is cooled and formed, different metal liquid will be added in the next processing, which will cause different metals to be contained in the next metal processing, resulting in unqualified products after die-casting. Therefore, it is only necessary to wait for cooling, unscrew the first bolt 9, and separate the first shot cylinder 1 and the second shot cylinder 2. In this way, the residual metal liquid can be replaced in the second shot cylinder 2, and then the cooled bushing 4 can be rotated out of the second shot cylinder 2. The second shot cylinder 2 and the bushing 4 with or without utilization value can be replaced in two different ways, which greatly reduces the processing cost.
[0018] like Figure 1 and Figure 2As shown, it also includes a pressing plate 10 and a heat-resistant sealing ring 11. The pressing plate 10 is installed on one end of the second injection cylinder 2 close to the first feed port 3. The heat-resistant sealing ring 11 is installed between the pressing plate 10 and the first feed port 3, and the three are sealed and abutted. The pressing plate 10 is evenly provided with a plurality of first positioning holes 12, and the bushing 4 is provided with a plurality of second positioning holes 13, and the plurality of first positioning holes 12 and the plurality of second positioning holes 13 are mutually connected in a one-to-one correspondence, and the first positioning holes 12 and the second positioning holes 13 are both threaded hole structures; it also includes a plurality of second bolts 14, and the plurality of second bolts 14 are threadedly connected and penetrated through the corresponding first positioning holes 12 and the second positioning holes 13 in a one-to-one correspondence. The first shot cylinder 1 is provided with a hanging hole 16, the inside of the bushing 4 and the place connected with the first shot cylinder 1 is a shot chamber 15, the first feed port 3, the second feed port 5 and the shot chamber 15 are connected, and the first shot cylinder 1 and the second shot cylinder 2 are made of SKD61 metal with a hardness of HRC46-48.
[0019] The heat-resistant sealing ring 11 provided can reduce the impact force of the tail of the punch on the pressure plate 10 during the punch processing, so that after the pressure plate 10 is hit again, the pressure plate 10 forms an impact on the bushing 4, resulting in wear between the pressure plate 10 and the bushing 4. Therefore, a heat-resistant sealing ring is provided between the pressure plate 10 and the bushing 4 to achieve the effect of mitigation, thereby protecting the second shot cylinder 2. The lifting hole 16 provided on the first shot cylinder 1 can lift the first shot cylinder 1 to a certain height and facilitate installation in the die-casting machine. The material of the first shot cylinder 1, the second shot cylinder 2 and the bushing 4 is SKD61 metal material, which further improves the high temperature resistance and wear resistance of the first shot cylinder 1, the second shot cylinder 2 and the bushing 4.
[0020] Working principle:
[0021] In actual application, residual metal liquid will condense on the inner wall of the bushing 4 after cooling. After the metal liquid is cooled and formed, different metal liquid will be added in the next processing, which will cause different metals to be contained in the next metal processing, resulting in unqualified products after die-casting. Therefore, it is only necessary to wait for cooling, unscrew the first bolt 9 from the lock hole 8 and the through hole 7 in turn, and separate the first shot cylinder 1 and the second shot cylinder 2. In this way, the residual metal liquid can be replaced in the second shot cylinder 2, and then the cooled bushing 4 can be rotated out of the second shot cylinder 2. In this way, the first shot cylinder 1, the second shot cylinder 2 and the bushing 4 that cannot be processed further can be replaced, and the entire die-casting barrel will not be directly replaced every time the metal liquid hardens in the first shot cylinder 1, the second shot cylinder 2 and the bushing 4 and cannot be processed, thereby reducing the processing cost.
[0022] Then, the heat-resistant sealing ring 11 can be set to reduce the punch processing. First, the heat-resistant sealing ring 11 is attached to the edge of the second pressing cylinder 2, and then the pressing plate 10 is aligned with the second pressing cylinder 2. At this time, the second positioning hole 13 on the second pressing cylinder 2 is connected with the first positioning hole 12 on the pressing plate 10. The operator only needs to pass the second bolt 14 through the first positioning hole 12 and the second positioning hole 13 in sequence. In the following processing, the tail of the punch will form a certain impact force on the pressing plate 10, so that the pressing plate 10 is hit again Afterwards, the pressing plate 10 impacts the bushing 4, resulting in wear between the pressing plate 10 and the bushing 4. Therefore, a heat-resistant sealing ring is provided between the pressing plate 10 and the bushing 4 to achieve a mitigating effect, thereby protecting the second shot cylinder 2. The hoisting hole 16 provided on the first shot cylinder 1 can hoist the first shot cylinder 1 to a certain height and facilitate installation into the die-casting machine. The material of the first shot cylinder 1, the second shot cylinder 2 and the bushing 4 is SKD61 metal material, which further improves the high temperature resistance and wear resistance of the first shot cylinder 1, the second shot cylinder 2 and the bushing 4.
