Description

Technical Field

[0001] This application relates to the field of die casting machine technology, and in particular to a die casting machine drawing structure. Background Technology

[0002] Most current die-casting machines use a toggle-type mold clamping device, which generally includes a mechanical base with a head plate, a middle plate, and a tail plate. The head plate is fixed to the base, and one end of the toggle connecting rod is fixed to the tail plate, while the other end is connected to the middle plate. The three base plates are connected by four tie rods to form a load-bearing frame. As the toggle connecting rod opens and closes, it drives the middle plate to slide back and forth, thereby completing the die-casting opening and closing.

[0003] To facilitate the installation and disassembly of large molds, it is usually necessary to remove one or two top tie rods to create more operating space. During disassembly, a hydraulic cylinder is used to disengage a blocking component from the gear nut to release the tie rod locking mechanism (see patent CN217044536U). However, this method has a problem: if the hydraulic cylinder malfunctions, the blocking component may shift and disengage from the gear nut, causing axial displacement of the tie rod and potentially leading to a safety accident. Therefore, how to improve the existing tie rod removal structure to overcome these problems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] One of the objectives of this application is to provide a die-casting machine drawing structure.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a die-casting machine pull-out structure, including a base, a telescopic component, a blocking component, a connecting component, and a limiting component. The base is installed at the tail plate of the die-casting machine. The telescopic component is installed at the end of the base. The blocking component is slidably disposed in the base and cooperates with one end of the tie rod at the tail plate. The connecting component is slidably disposed at the end of the blocking component and connected to the piston end of the telescopic component. The limiting component is disposed on the side of the base and cooperates with the blocking component and the connecting component. When the tie rod is locked, the connecting component abuts against the blocking component, and the limiting component is adapted to lock the blocking component. When the tie rod is unlocked, the telescopic component is adapted to drive the limiting component to release the locking of the blocking component through the connecting component, and the connecting component is adapted to drive the blocking component to move synchronously away from the tie rod.

[0006] Preferably, the limiting component includes a limiting block and a limiting groove disposed on the side of the blocking member. The limiting block is elastically slidably disposed on the base and cooperates with the connecting member through a guide structure. When the limiting block cooperates with the limiting groove, the blocking member is in a locked state. When the connecting member is adapted to drive the limiting block away from the limiting groove through the guide structure, the blocking member is in an unlocked state.

[0007] Preferably, the guiding structure includes a guide bar and a guide groove disposed on the limiting block, the guide bar being installed on the connector; the guide bar is adapted to drive the limiting block to move and disengage from the limiting groove by wedge-shaped pressing engagement with the guide groove.

[0008] Preferably, the guide strip side has a first side surface, an inclined surface, and a second side surface, with the first side surface and the second side surface transitioning together via the inclined surface; the guide groove is adapted to move from the first side surface and through the inclined surface to the second side surface, thereby realizing the disengagement of the limiting block from the limiting groove.

[0009] Preferably, the die-casting machine pull-out structure further includes a head plate, a pair of clamping blocks, and a driving device. The other end of the pull column is disposed on the head plate, the clamping blocks are symmetrically slidably disposed on the head plate and located on both sides of the pull column, and the driving device is installed on the clamping blocks. The driving device is adapted to drive the clamping blocks to move relative to each other, thereby locking and unlocking the other end of the pull column.

[0010] Preferably, the driving device is a hydraulic cylinder, the piston end of the hydraulic cylinder is connected to one of the clamping blocks, the cylinder body of the hydraulic cylinder is connected to the other clamping block through a connecting rod, and the connecting rod passes through one of the clamping blocks.

[0011] Preferably, each of the pair of clamping blocks is equipped with a matching pressure plate on its side, and the pressure plate is provided with a detection module, which is adapted to detect the locking position, disengagement position and locking force of the clamping block.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: This invention incorporates a limiting component. When the blocking component locks and limits the guide column, the limiting component can lock the blocking component. In this way, even if the telescopic component malfunctions, the limiting component can ensure that the blocking component remains in the locked position and will not shift, thereby guaranteeing stable axial positioning of the guide column.

[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 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.

[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] One preferred embodiment of this application, such as Figures 1 to 8 As shown, a die-casting machine pull-out structure includes a base 4, a telescopic member 8, a blocking member 6, a connecting member 7, and a limiting component 9. The base 4 is installed at the tail plate 1 of the die-casting machine, the telescopic member 8 is installed at the end of the base 4, the blocking member 6 is slidably disposed in the base 4 and cooperates with one end of the pull post 3 at the tail plate 1, the connecting member 7 is slidably disposed at the end of the blocking member 6 and connected to the piston end of the telescopic member 8, and the limiting component 9 is disposed on the side of the base 4 and cooperates with the blocking member 6 and the connecting member 7.

[0026] Understandably, when it is necessary to limit and lock one end of the goblin post 3, the telescopic member 8 will push the blocking member 6 through the connecting member 7 until the blocking member 6 moves to the first locked position, that is, the blocking member 6 will engage with the gear nut 5 on the goblin post 3, and the connecting member 7 and the blocking member 6 will also be in a resisting state. At this time, the limiting component 9 locks the blocking member 6. In this way, when the telescopic member 8 fails, the limiting component 9 can ensure that the blocking member 6 is in the locked position and will not move, thereby ensuring the axial stability of the goblin post 3. When unlocking the goblin post 3, the telescopic member 8 will first cause the connecting member 7 to move, and the connecting member 7 will act on the limiting component 9 to release the locking of the blocking member 6; then the connecting member 7 will drive the blocking member 6 to move synchronously away from the goblin post 3, so that the blocking member 6 moves to the second unlocked position.

[0027] As a further description of the above embodiments: such as Figure 4 and Figure 5 As shown, the limiting component 9 includes a limiting block 901 and a limiting groove 902 disposed on the side of the blocking member 6. The limiting block 901 can be elastically slidably disposed on the seat 4 by a spring and cooperate with the connecting member 7 through the guide structure 10.

[0028] Understandably, when the limiting block 901 is spring-loaded into the limiting groove 902, the blocking member 6 will be in a locked state. When the connecting member 7 drives the limiting block 901 to separate from the limiting groove 902 through the guide structure 10, the blocking member 6 will be in an unlocked state.

[0029] like Figure 5As shown, the guide structure 10 includes a guide bar 1001 and a guide groove 1002 disposed on the limiting block 901. The guide bar 1001 is mounted on the connector 7. It can be understood that the guide bar 1001 can drive the limiting block 901 to move and disengage from the limiting groove 902 through a wedge-shaped pressing engagement with the guide groove 1002. Specifically, the guide bar 1001 has a first side surface 11, an inclined surface 12, and a second side surface 13 on its side, with the first side surface 11 and the second side surface 13 transitionally engaged through the inclined surface 12.

[0030] To provide a more detailed understanding of the locking and unlocking process of the Golem 3, its working principle is described below: ①For example Figure 2 As shown, assuming this is the initial state, one end of the guide post 3 is in a limited locking state, while the blocking member 6 is in the first locked state. At this time, the connecting member 7 also abuts against the blocking member 6; as Figure 4 As shown, the limiting block 901 abuts against the limiting groove 902 under the action of elastic force, thereby locking and limiting the blocking member 6; while the first side 11 of the guide strip 1001 cooperates with the guide groove 1002. ② When it is necessary to unlock the goblin post 3: as Figure 6 As shown in the figure below, the connecting piece 7 moves to the right under the action of the telescopic piece 8, which causes the guide strip 1001 to move to the right synchronously. At this time, the guide groove 1002 will cooperate with the inclined surface 12 of the guide strip 1001. Under the wedge-shaped pressing cooperation, the limiting block 901 will move and separate from the limiting groove 902. When the guide groove 1002 cooperates with the second side surface 13 of the guide strip 1001, the limiting block 901 and the limiting groove 902 are in a separated state, that is, the locking of the blocking piece 6 is released. Subsequently, the connecting piece 7 continues to move to the right, and the connecting piece 7 and the limiting piece also slide relative to each other to the limit distance. Therefore, the connecting piece 7 will pull the limiting piece to move synchronously until the limiting piece separates from the gear nut 5, thereby releasing the locking of the goblin column 3, that is, the blocking piece 6 is in the unlocked second state position. ③ When it is necessary to lock the golem 3, the telescopic member 8 pushes the blocking member 6 from the second state position to the first state position through the connecting member 7. At this time, the limiting block 901 and the limiting groove 902 are in the corresponding state, and the first side 11 of the guide bar 1001 cooperates with the guide groove 1002 again. Then the limiting block 901 will be stuck into the limiting groove 902 under the action of elasticity, thereby locking the blocking member 6 again.

[0031] In one embodiment of this application, such as Figure 1 and Figure 7As shown, the die-casting machine's gate pull structure also includes a head plate 2, a pair of clamping blocks 14, and a drive device 15. The other end of the gate pull 3 is disposed on the head plate 2. The clamping blocks 14 (preferably open-end nuts) are symmetrically slidably disposed on the head plate 2 and located on both sides of the gate pull 3. The drive device 15 is mounted on the clamping blocks 14. It can be understood that the drive device 15 can drive the clamping blocks 14 to move relative to each other, thereby locking and unlocking the other end of the gate pull 3.

[0032] As a further description of the above embodiments: such as Figure 7 and Figure 8 As shown, the drive device 15 preferably employs a hydraulic cylinder. The piston end of the hydraulic cylinder is connected to the left clamping block 14, and the cylinder body is connected to the right clamping block 14 via a connecting rod 18, with the connecting rod 18 passing through the left clamping block 14. It is understood that, as Figure 8 As shown in the diagram above, the two clamping blocks 14 abut against the other end of the gatepost 3, thereby limiting and locking it. During unlocking: the hydraulic cylinder shortens, causing the left clamping block 14 to move to the left until it stops. If the hydraulic cylinder continues to shorten, it will move to the right, which in turn causes the right clamping block 14 to move to the right via the connecting rod 18. In other words, the two clamping blocks 14 move in opposite directions and away from the gatepost 3, thus unlocking the gatepost 3. Figure 8 As shown in the figure below. In other words, the two clamping blocks 14 can be controlled and driven by a single hydraulic cylinder, thereby simplifying the entire limiting structure and reducing manufacturing costs.

[0033] Furthermore, mating pressure plates 16 can be installed on the sides of both clamping blocks 14. A detection module 17 can be installed on the pressure plate 16, which, through some sensor components, can detect the position, separation state, and locking force during mold clamping in real time. Of course, the structural principle of the detection module 17 is common knowledge to those skilled in the art, and therefore will not be elaborated further.

[0034] Finally, it should be noted that the specific structure and working principle of the telescopic component 8 and the drive device 15 are well known to those skilled in the art, and therefore will not be described in detail here; common types include hydraulic cylinders, pneumatic cylinders and linear motors, etc., and those skilled in the art can choose according to actual needs.

[0035] 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.
