Description

Technical Field

[0001] The invention relates to the technical field of die-casting machines, and in particular to a die-casting barrel. Background Art

[0002] In amorphous die-casting equipment, due to the high temperature of the melt of amorphous (liquid metal) raw materials, the die-casting barrel is easily damaged and is the main vulnerable part. The price of the die-casting barrel is high, and the life is not long enough. The cost of damage and replacement is high, and the cost of maintenance and replacement will eventually be passed on to the cost of amorphous products. At the same time, due to the short life of the die-casting barrel, their disassembly takes a long time, which will waste more working time on disassembly, assembly and replacement, and the reduction in work efficiency will also increase the cost of amorphous products.

[0003] At present, most die-casting barrels are integral, and the die-casting barrel is often installed on the barrel bushing, and the barrel bushing is fixed on the fixed plate of the equipment. The steps of the die-casting barrel and the barrel bushing are stuck between the gate sleeve and the fixed plate on the mold. When the die-casting barrel is damaged, it is necessary to remove the mold, remove the die-casting barrel, install a new die-casting barrel, and then install the mold back on the equipment. The cost of this integral die-casting barrel is relatively high, and the disassembly and assembly process is also time-consuming. Summary of the invention

[0020] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0021] The terms used in the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "the" and "the" used in the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0022] like Figure 1As shown, a die-casting barrel comprises a first barrel liner 1, a second barrel liner 2 and a barrel outer sleeve 3. The first barrel liner 1 and the second barrel liner 2 are sleeved in the barrel outer sleeve 3. The outer end face of the first barrel liner 1 is connected with a pressing sleeve 4, and the outer end face of the second barrel liner 2 is connected with a gate sleeve 5. The inner end face of the first barrel liner 1 is fitted with the inner end face of the second barrel liner 2, and the side faces of the first barrel liner 1 and the barrel outer sleeve 3 on the same side are provided with a through feed port 6.

[0023] As described above, the barrel liner of the die-casting barrel of the present invention is a straight barrel and is divided into two parts, namely, the first barrel liner 1 and the second barrel liner 2, which are fitted and connected. Among them, the first barrel liner 1 is as short as possible, and the second barrel liner 2 is as long as possible. The first barrel liner 1, the second barrel liner 2 and the barrel outer sleeve 3 are all clearance-matched to facilitate disassembly and assembly.

[0024] When in use, the mold 10 is equipped with a sprue sleeve 5 and a fixed plate 11, the barrel outer sleeve 3 is fixed on the fixed plate 11, and the steps of the barrel outer sleeve 3 and the second barrel liner 2 are stuck between the sprue sleeve 5 and the fixed plate 11. The pressing sleeve 4 is fixed on the barrel outer sleeve 3 to press the first barrel liner 1, and the fixing method can be screw fixing; the second barrel liner 2 and the sprue sleeve 5 are tightly fitted. In this way, the pressing sleeve 4 and the sprue sleeve 5 can press the first barrel liner 1 and the second barrel liner 2 respectively, so that the first barrel liner 1 and the second barrel liner 2 can be fixed together and not move.

[0025] In one embodiment of the present invention, the outer end surface of the first barrel liner 1 is provided with a first positioning hole 7 for positioning and disassembly. Figure 2 As shown. The pressing sleeve 4 is fixed on the barrel outer sleeve 3, and the pressing sleeve 4 passes through the first positioning hole 7 of the first barrel liner 1 to prevent the first barrel liner 1 from rotating, so as to ensure that the feed port between the first barrel liner 1 and the barrel outer sleeve 3 is aligned. After removing the pressing sleeve 4, the first positioning hole 7 of the first barrel liner 1 can also be used to take out the first barrel liner 1 from the side of the pressing sleeve 4.

[0026] In one embodiment of the present invention, the inner end surface of the second barrel liner 2 is provided with a second positioning hole 8 for positioning, rotation and disassembly. Figure 3 There can be multiple second positioning holes 8, evenly distributed on the inner end surface of the second barrel liner 2, for example, distributed at equal intervals around the circumference.

[0027] One of the second positioning holes 8 on the second barrel liner 2 cooperates with the first barrel liner 1 to prevent the second barrel liner 2 from rotating. If the lowermost area of ​​the second barrel liner 2 is damaged after a period of use, a tool can be inserted into any second positioning hole 8 and moved to rotate the second barrel liner 2 to an angle, and the other second positioning hole 8 of the second barrel liner 2 cooperates with the first barrel liner 1 to continue using it. After removing the pressing sleeve 4 and the first barrel liner 1, the second positioning hole 8 on the second barrel liner 2 can be used to remove the second barrel liner 2 from the side of the pressing sleeve 4.

[0028] In addition, if Figure 4 As shown, the first barrel liner 1, the second barrel liner 2 and the gate sleeve 5 are all positioned in the hole of the barrel outer sleeve 3, and the inner holes of the first barrel liner 1, the second barrel liner 2 and the gate sleeve 5 can be concentric, so that it can be ensured that the injection head 9 can move freely in the inner holes of the first barrel liner 1, the second barrel liner 2 and the gate sleeve 5. After the amorphous raw material 12 (liquid metal) enters from the feed port of the first barrel liner 1, the injection head 9 can push the amorphous raw material 12 to the left out of the gate sleeve 5 and into the mold. After removing the pressing sleeve 4, the first barrel liner 1 can be taken out and loaded from the side of the pressing sleeve 4, and the second barrel liner 2 can be rotated and taken out and loaded. These operations do not require the mold 10 on the side of the gate sleeve 5 to be disassembled.

[0029] The amorphous raw material 12 enters from the feed port 6 of the first barrel liner 1, is pushed to the left by the injection head 9 out of the gate sleeve 5 and enters the mold 10, and this process is repeated periodically. Since the temperature of the amorphous raw material is very high, after a period of time, the lowermost areas of the first barrel liner 1 and the second barrel liner 2 will be damaged. At this time, remove the pressing sleeve 4, remove the first barrel liner 1, rotate the second barrel liner 2 by an angle, install a new first barrel liner 1, and install the pressing sleeve 4. In this way, production can continue. After a period of production, if the barrel liner is damaged again, you can replace it with a new first barrel liner 1 and rotate the second barrel liner 2. After several angles of the second barrel liner 2 have been used, you can replace it with a new second barrel liner 2.
