Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an upper module structure and a mold. Background Technology

[0002] With the increasing demand for precision stamped parts such as automotive electronics, molds are needed for stamping parts for extended periods of time. As the frequency of mold use increases, the frequency of replacement or maintenance of corresponding components in the mold also increases. Among them, the upper stripper plate, as a component that is frequently replaced during forming, has a significantly increased replacement frequency.

[0003] In the existing technology, the upper stripper plate is connected to the stripper back plate through an equal-height sleeve; however, when the upper stripper plate needs to be replaced, the entire mold needs to be disassembled before the upper stripper plate can be disassembled, which increases the replacement cycle of the upper stripper plate. Utility Model Content

[0004] The purpose of this utility model is to provide an upper module structure and a mold, which can solve the above-mentioned technical problems;

[0005] This utility model provides an upper module structure, including an upper mold base and an upper pad plate disposed on the upper mold base, with one end of a plurality of guide rods passing through the upper mold base, and the upper pad plate passing through the plurality of guide rods; it also includes:

[0006] The upper clamping plate is set on the upper pad and passes through several guide rods;

[0007] Both the back panel and the upper panel are mounted on several guide rods, with the upper panel mounted on the back panel.

[0008] Several linkage devices are installed at one end on the upper clamping plate and at the other end engaged with the back plate.

[0009] Preferably, the linkage device is detachably connected to the upper clamping plate.

[0010] As a further technical solution, the linkage device includes a connecting section and a first hook section, with the first hook section disposed on the connecting section; in the installed state, the connecting section is disposed on the upper clamping plate, and the first hook section is engaged with the back plate.

[0011] As a further technical solution, the linkage device also includes:

[0012] The second hook section is set on the connecting section and is positioned opposite to the connecting section; in the installed state, the second hook section is engaged with the upper clamping plate.

[0013] As a further technical solution, the connecting section is provided with mounting holes, and the upper clamping plate is provided with fixing holes; in the installed state, the connecting section and the upper clamping plate are fixed by passing the fastener through the mounting holes and fixing holes.

[0014] As a further technical solution, a first slot is provided on the upper clamping plate; in the connected state, one end of the linkage device is placed in the first slot.

[0015] As a further technical solution, a second slot is provided on the back plate; in the connected state, the other end of the linkage device is placed in the second slot.

[0016] As a further technical solution, a first protrusion is formed between the upper pad and the upper clamping plate.

[0017] As a further technical solution, a second protrusion is formed between the back plate and the upper plate.

[0018] This utility model also proposes a mold, including a lower module structure and an upper module structure, with several guide rods passing through the lower module structure.

[0019] The technical solution of this utility model involves connecting one end of several linkage devices to the upper clamping plate, and the other end engaging the back-mounting plate. During mold opening, the upper mold base and upper pad move, which in turn drives the back-mounting plate via the linkage devices, causing the upper ejector plate to move simultaneously. During mold closing, the upper mold base drives the upper pad, causing the upper pad to slide along several guide rods. When the upper clamping plate contacts the back-mounting plate, the simultaneous movement of the back-mounting plate and the upper ejector plate completes the mold closing operation. During the back-mounting plate's movement, the linkage devices... The actuator limits the movement; when the upper ejector plate needs to be disassembled, the mold needs to be in the open state, and several linkage devices need to be disassembled; several connecting devices are separated from the upper clamping plate, and after the linkage devices are disassembled, the back plate is disassembled from the upper ejector plate; compared with the prior art, the position of the back plate can be limited by several linkage devices, while the upper ejector plate action is not affected when the mold is opened and closed; and when the upper ejector plate is disassembled, it can be disassembled after only several linkage devices are disassembled; thereby reducing the upper ejector plate replacement cycle and further shortening the downtime.

Detailed Implementation

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1-5 As shown, the present invention proposes an upper mold assembly structure, including an upper mold base 100 and an upper pad 200 disposed on the upper mold base 100. Several guide rods 300 have one end inserted into the upper mold base 100, and the upper pad 200 is disposed on the guide rods 300. The upper mold base 100 is connected to an injection molding machine. Under the drive of the injection molding machine, the upper mold base 100 moves, and in the process of moving, it drives the upper pad 200 to move simultaneously. An upper clamping plate 400 is disposed on the upper pad 200 and is disposed on the guide rods 300. When the upper pad 200 moves under the drive of the upper mold base 100, it drives the upper clamping plate 400 to move on the guide rods 300. The number of guide rods 300 depends on the actual situation; in this invention, preferably, four guide rods 300 are provided.

[0032] Both the back-mounted ejector plate 500 and the upper ejector plate 600 are mounted on several guide rods 300, with the upper ejector plate 600 positioned on the back-mounted ejector plate 500. Several linkage devices 700 are positioned at one end on the upper clamping plate 400 and at the other end engaged with the back-mounted ejector plate 500. During mold closing, the upper mold base 100 drives the upper pad plate 200 and the upper clamping plate 400 to move. Due to the presence of the linkage devices 700, the upper clamping plate 400, during its movement, drives the back-mounted ejector plate 500 and the upper ejector plate 600 to move simultaneously. After the upper clamping plate 400 moves a certain distance, the upper ejector plate 600 contacts the lower mold assembly structure. At this point, the upper ejector plate 600... The back plate 500 cannot continue to move; however, the upper clamping plate 400 will continue to move until it contacts the back plate 500. When the mold opens, the upper mold base 100 drives the upper pad 200 and the upper clamping plate 400 to move on the guide rod 300. As the upper clamping plate 400 moves, it separates from the back plate 500. After the upper clamping plate 400 moves a certain distance, due to the presence of several linkage devices 700, the back plate 500 and the upper ejector plate 600 will be lifted by the upper pad 200. With the simultaneous movement of the upper pad 200 and the upper clamping plate 400, the separation from the lower mold structure is completed.

[0033] As usage frequency increases, when it is necessary to replace the upper ejector plate 600, it needs to be in the mold open state. Since the linkage device 700 is detachably connected to the upper clamping plate 400, after separating several linkage devices 700 from the upper clamping plate 400, the ejector plate 500 and the upper template can be separated, and then the upper template can be replaced.

[0034] The technical solution of this utility model involves connecting one end of several linkage devices 700 to the upper clamping plate 400, and engaging the other end with the ejector plate 500. During mold opening, the upper mold base 100 and the upper pad 200 move, which in turn drives the ejector plate 500 to move via the linkage devices 700, thereby simultaneously driving the upper ejector plate 600 to move. During mold closing, the upper mold base 100 drives the upper pad 200 to move, causing the upper pad 200 to slide on several guide rods 300. When the upper clamping plate 400 contacts the ejector plate 500, the simultaneous movement of the ejector plate 500 and the upper ejector plate 600 completes the mold closing operation. During the movement of the ejector plate 500... The upper ejector plate 600 is limited by several linkage devices 700. When the upper ejector plate 600 needs to be disassembled, the mold needs to be in the open state, and the linkage devices 700 need to be disassembled. This separates the linkage devices 700 from the upper clamping plate 400. After the linkage devices 700 are disassembled, the back ejector plate 500 is disassembled from the upper ejector plate 600. Compared with the prior art, the position of the back ejector plate 500 can be limited by several linkage devices 700, while the operation of the upper ejector plate 600 is not affected when the mold is opened and closed. When disassembling the upper ejector plate 600, it is only necessary to disassemble several linkage devices 700 to disassemble the upper ejector plate 600. This reduces the replacement cycle of the upper ejector plate 600 and further shortens the downtime.

[0035] like Figure 4 As shown, the linkage device 700 includes a connecting section 701 and a first hook section 702, with the first hook section 702 disposed on the connecting section 701. In the installed state, the connecting section 701 is disposed on the upper clamping plate 400, and the first hook section 702 is engaged with the backing plate 500. In this utility model, it is necessary to ensure a fixed connection between the connecting section 701 and the upper clamping plate 400, and to be able to move simultaneously with the upper clamping plate 400. During the operation, the first hook section 702 can restrict the backing plate 500. In the mold-opening state, the backing plate 500 and the upper ejector plate 600 are lifted by engaging the connecting section 701 with the backing plate 500. In the mold-closed state, the connecting section 701 hooks the backing plate 500 and the upper ejector plate 600, allowing the backing plate 500 and the upper ejector plate 600 to move simultaneously with the upper clamping plate 400.

[0036] Of course, considering the strength of the fixation between the connecting section 701 and the upper clamping plate 400, and to avoid deformation due to the weight of the detachment back plate 500 and the upper detachment plate 600, a second hook section 703 is also provided. The second hook section 703 is set on the connecting section 701 and is positioned opposite to the connecting section 701. In the installed state, the second hook section 703 is engaged with the upper clamping plate 400. In this way, through the cooperation of the connecting section 701 and the second hook section 703, double fixation with the upper clamping plate 400 is achieved, thereby improving the fixation strength between the connecting section 701 and the upper clamping plate 400.

[0037] like Figure 3 and Figure 4 As shown, the connecting section 701 has a mounting hole 704, and the upper clamping plate 400 has a fixing hole 401. In the installed state, the connecting section 701 and the upper clamping plate 400 are fixed by passing a fastener through the mounting hole 704 and the fixing hole 401. In this utility model, the fixing hole 401 is preferably provided with an internal thread, and the fastener is threaded to the fixing hole 401 after passing through the mounting hole 704. In this utility model, the fastener is preferably a bolt.

[0038] In this utility model, to further increase the stability between the several linkage devices 700 and the upper clamping plate 400, a first slot 402 is preferably provided, which is formed on the upper clamping plate 402; for example Figure 5 As shown, in the connected state, one end of the linkage device 700 is placed in the first slot 402; this can limit the position of the linkage device 700 through the first slot 402 and prevent the linkage device 700 from being displaced during use.

[0039] In addition, since several linkage devices 700 need to bear the weight of the back plate 500 and the upper ejector plate 600, and the back plate 500 and the upper ejector plate 600 also need to move between the linkage devices 700 during the mold closing stage, in order to ensure that the back plate 500 and the upper ejector plate 600 do not shift when moving between the linkage devices 700, a second slot 501 is preferably provided. The second slot 501 is formed on the back plate 500. In the connected state, the other end of the linkage device 700 is placed in the second slot 501. Through the cooperation between the second slot 501 and the linkage device 700, displacement of the back plate 500 during the operation stage can be avoided, thereby improving the stability of the connection and movement of the back plate 500 and the upper ejector plate 600.

[0040] like Figure 4 As shown, a first protrusion 801 is formed between the upper pad 200 and the upper clamping plate 400; a second protrusion 802 is formed between the back plate 500 and the upper release plate 600; when connected with the linkage device 700, the first hook section 702 and the second hook section 703 respectively engage with the first protrusion 801 and the second protrusion 802, thereby increasing the contact area between the linkage device 700 and the upper clamping plate 400 and the back plate 500, thereby increasing the stability of the linkage device 700.

[0041] It should be noted that the number of linkage devices 700 can be adjusted according to different usage conditions; two linkage devices 700 are provided on both sides of the upper clamping plate 400 and the back plate 500; or three linkage devices 700 can be provided on both sides of the upper clamping plate 400 and the back plate 500 according to the size changes of the upper clamping plate 400 and the back plate 500; the specific details shall be subject to the actual situation, and this utility model will not be further described.

[0042] This utility model also proposes a mold, including a lower mold assembly structure and an upper mold assembly structure, with several guide rods 300 passing through the lower mold assembly structure; the guide rods 300 ensure the accuracy of the movement trajectory of the upper clamping plate 400, the back plate 500, and the upper ejector plate 600, and correspond with the lower mold assembly structure when the mold is closed; in the use stage, the part to be processed is placed on the lower mold assembly structure, and the stamping operation of the part to be processed is completed after the lower mold assembly structure cooperates with the upper mold assembly structure; the lower mold assembly structure in this utility model is prior art, and will not be further described for the sake of space.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
