Description

Technical Field

[0001] The utility model relates to the technical field of die casting die parts, in particular to a split universal wear-resistant clamping ring punch. Background Art

[0002] A die-casting machine is an industrial casting machine that casts molten metal into a mold under pressure, cools it into shape, and obtains a solid metal casting after the mold is opened. The punch is an important component of the die-casting machine. It is connected by a shot rod and moves back and forth horizontally or vertically to press liquid metal into the die-casting mold to cool it into shape. After the mold is opened, a solid metal casting can be obtained.

[0003] At present, the injection rod in the die-casting machine is connected to the injection head through a thread. Different sizes of metal castings require injection heads of different sizes, which makes it impossible to connect the injection head with the injection rod of uniform size according to the size of the metal casting, increasing the production cost of the enterprise. In addition, the punch is divided into an integrated type and a split type. The integrated punch is very easy to wear during die-casting, and the entire punch needs to be replaced, which is very time-consuming. The split type usually has one or more retaining rings sleeved on the punch base, and the friction between the retaining ring and the inner wall of the die-casting cavity reduces the need to replace the entire punch. Only the retaining ring needs to be replaced, and bolt holes are provided on the retaining ring and the base, and the retaining ring and the base are fixed by bolts. When the injection rod is threadedly connected to the injection head, there is a situation where the retaining ring is driven to rotate, so that the bolt hole on the retaining ring is offset from the bolt hole on the base, and manual adjustment is required, which greatly reduces the installation efficiency.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0025] Embodiment 1

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1 to 6 As shown, a split universal wear-resistant retaining ring punch includes a base 1, an adapter 2 is connected to the top of the base 1, a pressing end 3 is connected to the bottom of the base 1, a first mounting hole 4 is opened on the base 1, a wear-resistant component 5 is arranged on the base 1, the wear-resistant component 5 includes a first steel ring 51 and a second mounting hole 52 opened on the first steel ring 51, a limiting component 6 is arranged between the first steel ring 51 and the base 1, and the limiting component 6 is used to limit the first steel ring 51 when the first mounting hole 4 corresponds to the second mounting hole 52.

[0028] like Figure 3 As shown, a cooling cavity 7 is provided on the base body 1 , and a connecting thread 8 is provided on the cooling cavity 7 , so that the cooling cavity 7 can cool the punch.

[0029] like Figure 4 As shown, the inner and outer walls of the connecting member 2 are respectively provided with an internal thread section 9 and an external thread section 10, the external thread section 10 cooperates with the connecting thread 8, and the connecting member 2 can match the substrate 1 of different sizes. The internal thread section 9 is engaged with the thread section on the injection rod, so that the injection rod is threadedly connected to the connecting member 2, and the punch is pushed for die casting.

[0030] like Figure 4As shown, the wear-resistant component 5 also includes a first copper ring 53 sleeved on the substrate 1, a second copper ring 54 sleeved on the substrate 1, and a second steel ring 55 sleeved on the substrate 1. The first copper ring 53, the second copper ring 54 and the second steel ring 55 are all provided with connecting grooves 56 on their upper surfaces, and the first steel ring 51, the first copper ring 53 and the second copper ring 54 are all provided with flanges 57 on their lower surfaces. The connecting grooves 56 and the flanges 57 cooperate with each other, and multiple steel rings are used to prevent bubbles from emitting in the casting. The elasticity and wear resistance of the multiple copper rings are utilized to play a role in buffering, shock absorption and lubrication during the movement, thereby improving the service life of the punch.

[0031] like Figure 2 and Figure 3 As shown, a trapezoidal boss 11 is provided on the bottom surface of the base 1, and a trapezoidal groove 12 is opened on the pressing end 3. The trapezoidal boss 11 cooperates with the trapezoidal groove 12. The pressing end 3 of the split structure is connected to the base through the trapezoidal groove 12 and the trapezoidal boss 11. When the pressing end 3 is worn, only the pressing end 3 can be replaced. Compared with the traditional one-piece punch structure, it achieves the effect of cost saving and quick replacement. At the same time, the trapezoidal structure makes the connection between the two more stable.

At this time, the first mounting hole 4 corresponds to the second mounting hole 52. When the connecting member 2 is threadedly connected to the base 1 or the injection rod is threadedly connected to the connecting member 2, since the connecting member 2 abuts against the first steel ring 51, the connecting member 2 and the injection rod drive the first steel ring 51 to rotate, causing the first mounting hole 4 and the second mounting hole 52 to deflect. By inserting the limiting block 61 into the limiting groove 62, the first mounting hole 4 and the second mounting hole 52 can always maintain a corresponding state.

[0034] Working process

[0035] First, insert the trapezoidal boss 11 into the trapezoidal groove 12 to connect the pressing end 3 to the base 1. Then, the second steel ring 55, the second copper ring 54, and the first copper ring 53 are successively sleeved on the base 1. The limit block 61 on the first steel ring 51 is inserted into the limit groove 62 to ensure that the first mounting hole 4 and the second mounting hole 52 always correspond to each other. Then, the connecting piece 2 is threadedly connected to the base 1, and finally the injection rod is threadedly connected to the connecting piece 2. During die casting, the water pipe in the injection rod injects cold water into the cooling chamber 7 to cool the base 1.
