Description

Technical Field

[0001] This application relates to the field of die casting machines, specifically to a tail plate casting structure in a die casting machine. Background Technology

[0002] The assembly process for the hinges of the middle and tail plate castings in existing die-casting machines is quite complicated and difficult. The middle and tail plate castings of die-casting machines require repeated adjustments, inspections, and grinding during the assembly of steel parts.

[0003] In the existing technology, each hinge lug on the middle plate and tail plate has an 8mm boss cast on both sides. When the middle plate and tail plate are processed and assembled, the bosses on both sides of the hinge lug need to be milled to 3mm first. Therefore, the process of assembling the large steel bracket using the middle plate and tail plate in the existing technology is more complicated, more difficult to assemble, less accurate and has a lower pass rate.

[0004] Therefore, it is now necessary to improve the installation structure of the tail plate in the existing die-casting machine. Utility Model Content

[0005] The purpose of this application is to provide an installation structure for the tail plate in a die-casting machine that can solve at least one of the defects in the above-mentioned background art.

[0006] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a tail plate casting structure in a die casting machine, including a casting and multiple large steel brackets; multiple sets of hinges are provided on the casting; the multiple large steel brackets are correspondingly installed on the multiple hinges; in any set of multiple hinges, the outer sides of the two hinges located on both sides are provided with bosses, and the bosses are suitable as a reference when the large steel brackets are installed.

[0007] Preferably, the thickness of the boss is 2-5mm.

[0008] Preferably, the width of the large steel rod is greater than the width of the hinge lug, so that when the large steel rod is installed on the hinge lug, at least one end protrudes from the end face of the hinge lug.

[0009] Preferably, the hinge lug is provided with a first oil port; the large steel screw is provided with a second oil port; the large steel screw is adapted to rotate around its own axis during installation, so that the second oil port and the first oil port are in corresponding positions.

[0010] Preferably, the large steel lever includes a smooth section and a rough section; the large steel lever is adapted to rotate via the rough section located outside the hinge when the smooth section is installed with the hinge lug.

[0011] Preferably, one end of the large steel section is provided with a toothed section to form the rough section.

[0012] Preferably, the rough section transitions or is interference-fitted with the hinge.

[0013] Preferably, the casting is made of medium plate.

[0014] Preferably, the casting is a tail plate.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] Compared to existing die-casting machine steel fitting installation structures, the boss designed in this application provides a reference benchmark for the large steel fitting during installation. Simultaneously, the roughened section on the large steel fitting allows for a more secure installation within the hinge lug, and its position can be adjusted more easily. This reduces the manufacturing processes for the middle and tail plates, as well as the product weight, without compromising the strength of the machine hinge. It also shortens material turnover time and lowers material and labor costs. Attached Figure Description

[0025] 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.

[0026] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, 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, and should not be construed as limiting the specific protection scope of this application.

[0027] 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.

[0028] 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.

[0029] One preferred embodiment of this application, such as Figures 1 to 4 As shown, a tail plate casting structure in a die casting machine includes a casting and multiple large steel lugs 3; multiple sets of hinges 10 are provided on the casting; the multiple large steel lugs 3 are correspondingly installed on the multiple hinges 10; in any set of multiple hinges 10, the outer sides of the two hinges 10 located on both sides are provided with bosses 100, and the bosses 100 are suitable as a reference when the large steel lugs 3 are installed.

[0030] It should be noted that the assembly process of the hinge lugs 10 of the middle and tail plate castings of the existing die casting machine is relatively complicated and difficult. The middle and tail plate castings of the die casting machine need to be repeatedly adjusted, inspected and polished when assembled with the large steel bracket 3, which results in low precision and low pass rate of the middle and tail plate castings after assembly with the large steel bracket 3.

[0031] Therefore, in this embodiment, the boss 100 designed in this application can provide a reference benchmark for the large steel bracket 3 during installation; at the same time, the rough section 32 on the large steel bracket 3 also allows the large steel bracket 3 to be installed more securely in the hinge lug 10, and its position can be adjusted more conveniently.

[0032] In this embodiment, as Figure 1 and Figure 3 As shown, the castings are preferably tail plate 1 and middle plate 2.

[0033] In the prior art, each hinge lug 10 on the middle plate 2 and the tail plate 1 has an 8mm boss 100 cast on both sides. When the middle plate 2 and the tail plate 1 are processed and assembled, the bosses 100 on both sides of the hinge lug 10 need to be milled to 3mm. Therefore, the process of assembling the large steel bracket 3 on the middle plate 2 and the tail plate 1 in the prior art is more complicated, more difficult to assemble, less accurate and less qualified.

[0034] In this embodiment, as Figures 1 to 4 As shown, four sets of hinge ears 10 are provided on the middle plate 2 and the tail plate 1. In each set of hinge ears 10, only the two hinge ears 10 located on the sides have bosses 100 on their outer sides. This reduces the manufacturing process and product weight of the middle plate 2 and the tail plate 1 without affecting the strength of the hinge, thus saving material turnover cycle and reducing material and labor costs.

[0035] Regarding the thickness of the boss 100, in this embodiment the thickness of the boss 100 is limited to 2-5mm.

[0036] In this embodiment, after the large steel bracket 3 is installed on the hinge lug 10, it is particularly inconvenient to disassemble it when necessary. If the large steel bracket 3 does not have any end protruding from the end face of the hinge lug 10 after assembly, in a single set of hinge lugs 10, only the large steel bracket 3 installed on the two hinge lugs 10 located on both sides may be easy to disassemble, while the large steel bracket 3 installed on the other hinge lugs 10 located on the inner side is not easy to disassemble.

[0037] Therefore, in this embodiment, as Figure 2 and Figure 4 As shown, the width of the large steel bracket 3 is greater than the width of the hinge lug 10, so that when the large steel bracket 3 is installed on the hinge lug 10, at least one end protrudes from the end face of the hinge lug 10, thereby making it easy to disassemble the large steel bracket 3 installed on either the outer or inner hinge lug 10 in a single set of hinge lugs 10.

[0038] It should be noted that die-casting machines have low-pressure and high-pressure stages during mold closing. Insufficient lubrication during these stages may increase friction and affect the service life of the mold.

[0039] Therefore, in this embodiment, as Figure 1 , Figure 3 as well as Figure 5 As shown, the hinge lug 10 is provided with a first oil port 101; the large steel screw 3 is provided with a second oil port 30. It is understood that it is not enough to simply provide the first oil port 101 and the second oil port 30; the positions of the first oil port 101 and the second oil port 30 must also correspond.

[0040] Therefore, during installation, the large steel pipe 3 is suitable for rotating around its own axis to make the second oil port 30 and the first oil port 101 correspond in position.

[0041] There are various ways to drive the large steel compressor 3 to rotate around its own axis, and those skilled in the art can choose according to actual needs; in this embodiment, such as Figures 5 to 7 As shown, the preferred method for driving the large steel rod 3 to rotate around its own axis is that the large steel rod 3 includes a smooth section 31 and a rough section 32; the large steel rod 3 is adapted to be driven to rotate by the rough section 32 located outside the hinge 10 when the smooth section 31 is installed with the hinge lug 10.

[0042] Specifically, the large steel screw 3 is divided into a smooth section 31 and a rough section 32. The smooth section 31 is suitable for extending into the hinge 10 and assembling with the hinge 10 during the assembly of the large steel screw 3. If the positions of the first oil port 101 on the hinge 10 and the second oil port 30 on the large steel screw 3 do not correspond at this time, the rough section 32 can be used to cooperate with external parts to drive the large steel screw 3 to rotate around its own axis until the positions of the first oil port 101 and the second oil port 30 correspond.

[0043] As can be seen from the above, the rough section 32 can cooperate with external parts to drive the large steel screw 3 to rotate. There are various specific ways to configure the rough section 32, and those skilled in the art can choose according to actual needs; in this embodiment, for example... Figure 5 As shown, one end of the large steel section 3 is provided with a toothed section 320 to form the rough section 32.

[0044] It is understandable that when the toothed section 320 is provided on the large steel plate 3, it can be connected to the toothed section 320 by gear meshing through an external rack or external gear so that the large steel plate 3 can rotate around its own axis; in this embodiment, the size of the toothed section 320 can be set to be flush with the outer surface of the smooth section 31, or it can be set to be slightly protruding from the outer surface of the smooth section 31.

[0045] It should be understood that the position of the second oil port 30 on the large steel screw 3 needs to correspond to the position of the first oil port 101 on the hinge lug 10. If the connection between the large steel screw 3 and the hinge lug 10 is not stable, even if the large steel screw 3 rotates through the rough section 32 to make the second oil port 30 and the first oil port 101 correspond, the second oil port 30 cannot stably correspond to the first oil port 101 during the operation of the equipment. Therefore, in this embodiment, the connection between the large steel screw 3 and the hinge lug 10 needs to be stabilized.

[0046] Therefore, in this embodiment, as Figure 6 and Figure 7 As shown, the toothed section 320 protrudes slightly from the outer surface of the smooth section 31, so that the rough section 32 is suitable for interference fit or transition fit with the hinge 10, thereby making the connection between the large steel rod 3 and the hinge 10 more stable.

[0047] 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.
