Description

Technical Field

[0001] This utility model relates to the field of die casting mold components, and more specifically to a bushing cylinder for a large-tonnage die casting machine. Background Technology

[0002] Pressure casting is a rapidly developing special casting method in modern metal processing technology, involving minimal or no cutting. It is a process in which molten metal is filled into a mold under high pressure and high speed, and then crystallized and solidified under high pressure to form a casting.

[0003] During the die casting process, the injection end of the barrel may crack due to the impact of high pressure. The aluminum pouring port at the feed end may be eroded and pitted due to long-term pouring of liquid, requiring the replacement of the entire barrel before it can be used normally. However, the front end of the barrel's inner hole remains intact, which greatly reduces the frequency of barrel use and increases the company's costs. In addition, some barrels use bolts to sleeve the injection end and feed end, but after long-term use, the bolts may crack at the connection, rendering the barrel unusable. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a bushing cylinder for a large-tonnage die-casting machine. An inner bushing is added at the injection end and the feed end, and a snap-fit ​​assembly engages the inner bushing with the injection end and the feed end. A fixing assembly further secures the inner bushing to the injection end and the feed end. The inner bushing is detachably and fixedly embedded in the injection end and the feed end, replacing the traditional bolt method, making it convenient to use, increasing the service life of the cylinder, and improving the frequency of cylinder use.

[0005] The technical solution of this utility model is as follows:

[0006] A bushing cylinder for a large-tonnage die-casting machine includes a cylinder body, an injection end, and a feeding end. Both the injection end and the feeding end are provided with placement grooves, and an inner bushing is provided in each placement groove. The inner bushing is provided with a snap-fit ​​assembly and a fixing assembly. The snap-fit ​​assembly is used to snap the inner bushing to the injection end and the feeding end, and the fixing assembly is used to fix the inner bushing to the injection end and the feeding end.

[0007] As a preferred embodiment, the buckle assembly includes several fixing rods fixedly mounted on the inner sleeve, a fixing plate fixedly mounted on the fixing rods, several sliding grooves formed on the injection end and the feed end, and a slot formed on the sliding grooves. The fixing rods cooperate with the slots, and the fixing plate cooperates with the sliding grooves and the slots.

[0008] As a preferred embodiment, the fixing component includes a first dovetail groove formed on the injection end and the feed end, a second dovetail groove formed on the inner sleeve, a dovetail pin disposed in the first dovetail groove and the second dovetail groove, and a fixing hole formed on the dovetail pin.

[0009] As a preferred embodiment, the feed end is provided with an external feed port, and the inner sleeve at the feed end is provided with an internal feed port, and the external feed port and the internal feed port cooperate with each other.

[0010] As a preferred embodiment, the inner sleeve is provided with anti-slip texture.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model is equipped with an inner sleeve. By placing the inner sleeve at the injection end and the feed end, the service life of the barrel is extended. When the inner sleeve is worn, it can be directly replaced.

[0013] 2. This utility model is also provided with a buckle assembly and a fixing assembly. By rotating the inner sleeve, the fixing plate slides into the slot, so that the inner sleeve can be quickly snapped into the injection end and the feed end. The dovetail nails are placed in the first dovetail groove and the second dovetail groove instead of bolts to fix the connection, which prevents cracking at the connection and improves the service life of the barrel.

[0014] In summary, this utility model has the advantages of quick replacement and long service life, and is suitable for the field of die-casting mold parts technology. Attached Figure Description

Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] like Figures 1 to 5 As shown, a bushing cylinder for a large-tonnage die-casting machine includes a cylinder body 1, an injection end 2, and a feeding end 3. Both the injection end 2 and the feeding end 3 are provided with placement grooves 4, and each placement groove 4 is provided with an inner bushing 5. The inner bushing 5 is provided with a snap-fit ​​assembly 6 and a fixing assembly 7. The snap-fit ​​assembly 6 is used to snap the inner bushing 5 to the injection end 2 and the feeding end 3, and the fixing assembly 7 is used to fix the inner bushing 5 to the injection end 2 and the feeding end 3. The replaceable inner bushing 5 structure improves the service life of the cylinder body 1.

[0026] Among them, such as Figures 1 to 4 As shown, the snap-fit ​​assembly 6 includes several fixing rods 61 fixedly mounted on the inner sleeve 5, a fixing plate 62 fixedly mounted on the fixing rods 61, several sliding grooves 63 opened on the injection end 2 and the feed end 3, and a slot 64 opened on the sliding grooves 63. The fixing rods 61 cooperate with the slots 64, and the fixing plate 62 cooperates with the sliding grooves 63 and the slots 64. In use, the fixing plate 62 is first placed into the sliding groove 63, and then the inner sleeve 5 is rotated so that the fixing rods 61 and the fixing plate 62 slide into the slots 64. At this time, the fixing plate 62 is snapped into the slots 64, so that the inner sleeve 5 is quickly snapped into the injection end 2 and the feed end 3.

[0027] In addition, such as Figure 1 As shown, the fixing component 7 includes a first dovetail groove 71 formed on the injection end 2 and the feed end 3, a second dovetail groove 72 formed on the inner sleeve 5, a dovetail pin 73 disposed in the first dovetail groove 71 and the second dovetail groove 72, and a fixing hole 74 formed on the dovetail pin 73. In use, when the inner sleeve 5 is engaged with the injection end 2 and the feed end 3, the first dovetail groove 71 and the second dovetail groove 72 are exactly aligned. Then, the dovetail pin 73 is placed in the first dovetail groove 71 and the second dovetail groove 72 for fixing, which replaces the traditional bolt fixing method, prevents cracks at the connection, and improves the service life of the barrel.

[0028] It is worth mentioning that, such as Figure 1As shown, an external feed port 8 is provided on the feed end 3, and an internal feed port 9 is provided on the inner sleeve 5 at the feed end 3. The external feed port 8 and the internal feed port 9 cooperate. When the inner sleeve 5 at the feed end 3 is rotated and engaged, the first dovetail groove 71 and the second dovetail groove 72 correspond to each other, and the internal feed port 9 corresponds to the external feed port 8, which facilitates the alignment of the internal feed port 9 and the external feed port 8 and facilitates liquid feeding.

[0029] Furthermore, such as Figure 3 As shown, the inner sleeve 5 is provided with anti-slip texture, which can prevent slippage when the inner sleeve 5 is rotated.

[0030] Work process

[0031] Place the fixing plate 62 on the inner sleeve 5 into the sliding groove 63, then rotate the inner sleeve 5 until the fixing plate 62 slides into the bottom of the slot 64. At the same time, the first dovetail groove 71 and the second dovetail groove 72 correspond. Place the dovetail nail 73 into the first dovetail groove 71 and the second dovetail groove 72 for fixation. When the inner sleeve 5 is worn, it can be replaced without replacing the entire barrel body 1, thus improving the service life of the barrel body 1.
