Description

Technical Field

[0001] This application relates to the field of die casting machines, and specifically to a die casting machine injection protection structure. Background Technology

[0002] The injection rod of a die-casting machine can be connected to an injection head, which injects molten metal at high temperatures. During injection, the injection head comes into direct contact with the molten metal, resulting in a very high temperature. This temperature is transferred to the injection rod, causing it to heat up as well. The injection rod requires an external water pipe for cooling, and cold water often splashes out at the connection point. To prevent this leakage and splashing into the furnace containing molten aluminum, a protective structure needs to be installed around the injection rod. Different injection scenarios may require different injection rod sizes, and the protective structure must be adjusted to accommodate these variations.

[0003] Therefore, it is now necessary to improve the existing injection protection structure of die-casting machines. Utility Model Content

Detailed Implementation

[0022] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0024] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0026] One preferred embodiment of this application, such as Figure 1 and Figure 2 As shown, a die-casting machine injection protection structure includes a protection component 1 and a support beam component 2; the support beam component 2 is connected to the die-casting machine body, and the protection component 1 and the support beam component 2 are fixedly connected, and the protection component 1 can protect the injection rod.

[0027] It should be understood that the injection rod of a die-casting machine can be connected to an injection head, which injects high-temperature molten metal. During injection, the injection head comes into direct contact with the molten metal, resulting in a very high temperature. This temperature is transferred to the injection rod, causing it to heat up as well. The injection rod requires an external water pipe for cooling, and cold water often splashes out at the connection point. To prevent this leakage and splashing into the furnace containing molten aluminum, a protective structure needs to be installed around the injection rod. Different injection scenarios may require different injection rod sizes, and the protective structure must be adjusted to accommodate these variations.

[0028] Therefore, compared with the traditional solution, the advantage of this solution is that the support beam assembly 2 is installed in conjunction with the body of the die casting machine, and the protective assembly 1 is fixedly installed on the support beam assembly 2 so that the connection between the protective assembly 1 and the support beam assembly 2 is more stable, so that the vibration generated by the die casting machine during operation will not affect the connection between the protective assembly 1 and the support beam assembly 2.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the protective assembly 1 includes a first protective member 10 and a second protective member 11; the first protective member 10 and the support beam assembly 2 are fixedly connected; the second protective member 11 covers the first protective member 10 and is slidably connected to the second protective member 11 through a guide structure. The support beam assembly 2 includes a pair of support beams 20; the pair of support beams 20 are fixedly connected through a connector 22; each of the opposite ends of the pair of support beams 20 is provided with a baffle 21; the baffle 21 can protect the injection rod.

[0030] It should be understood that, in this embodiment, the support beam 20 is used to connect with the body of the die-casting machine. The protective component 1 and the support beam 20 are fixedly connected, which is equivalent to the protective component 1 being connected to the body of the die-casting machine through the support beam 20. Therefore, in this embodiment, the support beam 20 is preferably fixedly connected to the body of the die-casting machine. As can be seen from the above, there is a pair of support beams 20. The pair of support beams 20 are fixedly connected at the end near the end connected to the body of the die-casting machine through the connector 22, so that the pair of support beams 20 can form a whole, thereby making the protective component 1 more stably installed on the body of the die-casting machine.

[0031] It should also be understood that the first protective member 10 and the support beam assembly 2 are fixedly connected; the support beam assembly 2 includes a pair of support beams 20, both of which are fixedly connected to the body of the die-casting machine, so the first protective member 10 and the pair of support beams 20 are both fixedly connected; the second protective member 11 covers the first protective member 10 and is slidably connected to the second protective member 11 through the guide structure. It can be understood that the installation position of the second protective member 11 is located above the first protective member 10, and then the second protective member 11 can slide through the aforementioned guide structure.

[0032] The aforementioned guide structure can be understood as connecting the first protective member 10 and the second protective member 11 via the guide structure to guide the sliding trajectory of the second protective member 11. There are various specific ways to configure the guide structure; in this embodiment, for example... Figure 1 As shown, the preferred configuration is that the first protective member 10 is provided with a guide post 100; the second protective member 11 is provided with a guide groove 110; the guide post 100 is adapted to pass through the guide groove 110 to form the guide structure.

[0033] Specifically, the first protective member 10 is provided with a guide post 100, and the second protective member 11 is provided with a guide groove 110. As can be seen from the above, the guide post 100 is suitable for passing through the guide groove 110. After the guide post 100 passes through the guide groove 110, since the first protective member 10 is fixedly connected to the support beam 20, it can be understood that the position of the guide post 100 will not change. This is equivalent to the guide post 100 restricting and guiding the sliding trajectory of the guide groove 110, so that the sliding trajectory of the guide groove 110 will not change.

[0034] In this embodiment, the guide post 100 on the first protective member 10 and the guide groove 110 on the second protective member 11 effectively control the sliding trajectory of the second protective member 11. After the second protective member 11 completes its sliding, it needs to be locked to maintain its position for operation. The locking effect of the guide post 100 and the guide groove 110 on the second protective member 11 is not very significant. If the second protective member 11 is not locked, the vibration generated by the die-casting machine body during operation may cause the position of the second protective member 11 to change.

[0035] Therefore, in this embodiment, as Figure 2 and Figure 3 As shown, the second protective member 11 is provided with a handle 111; the handle 111 is adapted to cooperate with the first protective member 10 through a limiting structure to lock the position of the second protective member 11.

[0036] As can be seen from the above, the handle 111 can be connected to the first protective member 10 through a limiting structure. First, it should be noted that the position of the first protective member 10 will not change in this embodiment. The connection between the handle 111 and the first protective member 10 through the limiting structure can be understood as the first protective member 10 limiting the handle 111 through the limiting structure. Since the handle 111 is set on the second protective member 11, the position of the second protective member 11 is locked.

[0037] In this embodiment, the handle 111 is elastically rotated and mounted on the second protective member 11 via an elastic element; the handle 111 is provided with a first limiting member 1110; the first protective member 10 is provided with a sliding groove 101 and a second limiting member 102; the first limiting member 1110 is adapted to cooperate with the second limiting member 102 to form a limiting structure.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, the handle 111 is elastically rotatable because this design allows the handle 111 to return to its original position under the elastic force of the elastic element after being manually rotated. A first limiting member 1110 is provided on the side of the handle 111. A second limiting member 102 is provided inside the first protective member 10. The first limiting member 1110 needs to extend into the inside of the first protective member 10 for limiting connection, and the handle 111 also needs to slide with the second protective member 11. Therefore, a sliding groove 101 is provided on the first protective member 10. The first limiting member 1110 can extend into the inside of the first protective member 10 through the sliding groove 101. When the first limiting member 1110 moves with the second protective member 11, it can move through the sliding groove 101.

[0039] There are various ways to specifically set the limiting structure described above; in this embodiment, such as... Figure 3 , Figure 5 as well as Figure 6 As shown, it is preferable to provide a limiting groove 1020 on the second limiting member 102; the first limiting member 1110 is adapted to extend into the limiting groove 1020 for locking; the handle 111 is adapted to rotate around the installation position so that the first limiting member 1110 disengages from the limiting groove 1020 to release the lock.

[0040] It is understood that the first limiting member 1110 is connected to the second limiting member 102 for limiting, so in this embodiment, multiple second limiting members 102 need to be provided; multiple second limiting members 102 can be provided at equal intervals along the sliding direction of the second protective member 11.

[0041] Regarding the aforementioned elastic element configuration, there can be various configurations; in this embodiment, such as... Figure 4 As shown, the elastic element is preferably a torsion spring 112.

[0042] To make it easier to understand, the working process of handle 111 will be explained in detail below.

[0043] Initially, such as Figure 5 As shown, the handle 111 is inclined, and the first limiting member 1110 is partially located within the limiting groove 1020. Since the first limiting member 1110 needs to rotate with the handle 11 around the mounting point, the movement trajectory of the first limiting member 1110 is arc-shaped. When the limiting groove 1020 is set, it is necessary to avoid interference with the first limiting member 1110 during rotation. When the first limiting member 1110 is partially located within the limiting groove 1020, since the second limiting member 102 is fixedly set on the first protective member 10, the position of the limiting groove 1020 will not change, so that the limiting groove 1020 can lock the position of the first limiting member 1110, thereby locking the position of the handle 111, that is, locking the position of the second protective member 11.

[0044] When it is necessary to release the position lock of the second protective component 11, such as Figure 6 As shown, by rotating the handle 111, the portion of the first limiting member 1110 located in the limiting groove 1020 is disengaged from the limiting groove 1020, so that the limiting groove 1020 can no longer lock the position of the first limiting member 1110, that is, the second protective member 11 is released from position locking; at this time, the handle 111 is no longer tilted, but is perpendicular to the side of the second protective member 11.

[0045] When the second protective member 11 moves to the set position, the handle 111 needs to be released so that the handle 111 returns to its original position under the elastic force of the torsion spring 112; the first limiting member 1110 engages with the limiting groove 1020 again to lock the position of the second protective member 11; at this time, the handle 111 will again be in the position of... Figure 5 The tilted state shown.

[0046] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
