Description

Technical Field

[0001] This utility model relates to the field of die-casting equipment technology, and in particular to a guide column structure and a two-plate die-casting machine. Background Technology

[0002] Two-plate die casting machines are generally equipped with multiple guide pillars. During the operation of the die casting machine, the two-plate structure needs to be moved by a hydraulic device to complete operations such as mold closing and mold opening. At this time, the guide pillars can limit and guide the two-plate structure, ensuring that the two-plate structure can move accurately along the preset mold opening and closing path, and avoiding lateral displacement of the two-plate structure during the movement.

[0003] In practical applications, it is sometimes necessary to adjust the guide pillars to accommodate different mold sizes and die-casting requirements. Based on these needs, a separate drive assembly is often required in the die-casting machine specifically for driving the guide pillars to complete the insertion and withdrawal action. This increases the structural complexity of the die-casting machine, leading to higher manufacturing and assembly costs. Utility Model Content

[0004] The main purpose of this utility model is to propose a guide column extraction structure, which aims to solve the technical problems of increased structural complexity and high manufacturing and assembly costs caused by the existing two-plate die-casting machines in order to achieve guide column extraction and adjustment.

[0005] To achieve the above objectives, the present invention proposes a guide column structure for a two-plate die-casting machine, which acts on a removable guide column. The removable guide column is slidably inserted into the two-plate structure. The guide column structure includes a rear locking cylinder, a locking block, and a clutch assembly. The rear locking cylinder is used to drive the locking block to engage the removable guide column.

[0006] The clutch assembly includes a locking member and a locking seat. The locking member is fixed to the locking block, and the locking seat is fixed to the two-plate structure. When the locking block is separated from the removable guide post, the locking member and the locking seat are fixedly connected.

[0007] In one embodiment, when the locking block engages with the retractable guide post, the pull rod cylinder drives the retractable guide post to slide, thereby separating the locking member from the locking seat.

[0008] In one embodiment, the locking seat has a groove, and the locking member includes a pin; when the locking member is fixedly connected to the locking seat, the pin is engaged in the groove; when the locking member is separated from the locking seat, the pin disengages from the groove.

[0009] In one embodiment, the groove includes a first groove segment and a second groove segment, the first groove segment and the second groove segment being bent and connected, and the second groove segment including a slot structure for locking the pin.

[0010] In one embodiment, the fastening element further includes a roller rotatably disposed on the outer periphery of the pin end, the roller sliding in the groove.

[0011] In one embodiment, the guide post structure includes at least two rear locking cylinders and at least two locking blocks; the at least two locking blocks are arranged at intervals along the circumference of the retractable guide post, and the at least two rear locking cylinders are connected to the at least two locking blocks in a one-to-one correspondence.

[0012] At least two of the rear locking cylinders are used to drive the corresponding locking blocks to press against the teeth of the removable guide post in order to engage and fix the removable guide post.

[0013] In one embodiment, the locking block has an arc-shaped pressing portion for engaging with the teeth of the retractable guide post.

[0014] This utility model also proposes a two-plate die casting machine, which includes a removable guide column, a two-plate structure, a connecting frame, and the aforementioned removable guide column structure;

[0015] The removable guide post is slidably inserted into the two-plate structure along the first path, and the fixing seat is fixed to the two-plate structure; the rear locking cylinder is disposed on the connecting frame, and the rear locking cylinder is used to drive the locking block to fix with the removable guide post;

[0016] When the locking block separates from the retractable guide post, the other end of the locking member is connected to the locking seat to lock the connecting frame and the two-plate structure together.

[0017] In one embodiment, the locking member includes a pin; the locking seat is provided with a groove, the groove including a first groove segment and a second groove segment, the first groove segment and the second groove segment being bent and connected;

[0018] When the locking member is fixedly connected to the locking seat, the pin is engaged in the slot structure of the second slot section; when the locking member is separated from the locking seat, the pin is disengaged from the slot structure of the second slot section.

[0019] In one embodiment, the two-plate die-casting machine further includes a positioning pin, which is disposed on the side of the two-plate structure facing the connecting frame; the connecting frame is provided with a positioning hole, and the positioning pin is slidably inserted into the positioning hole.

[0020] The guide column structure provided by this utility model adds a clutch assembly between the two-plate structure and the removable guide column. The clutch assembly includes a locking member mounted on a locking block and a locking seat mounted on the two-plate structure. When the locking block is fixed to the removable guide column, the locking member and the locking seat are separated. At this time, the removable guide column can be moved independently by the drive assembly to complete the insertion and removal adjustment operation. When the locking block is separated from the removable guide column, the locking member and the locking seat are fixed. At this time, the two-plate structure can be moved independently by the aforementioned drive assembly to complete the mold opening and closing operation. This solution utilizes the switching function of the simple clutch assembly to selectively transmit the power provided by the drive assembly to the two-plate structure or the removable guide column according to the usage needs. In this way, a single drive assembly can be used to drive both the two-plate structure and the removable guide column, thereby reducing the overall structural complexity of the two-plate die-casting machine and reducing manufacturing and assembly costs.

[0042] Two-plate die casting machines are generally equipped with multiple guide pillars. During the operation of the die casting machine, the two-plate structure needs to be moved by a hydraulic device to complete operations such as mold closing and mold opening. At this time, the guide pillars can limit and guide the two-plate structure, ensuring that the two-plate structure can move accurately along the preset mold opening and closing path, and avoiding lateral displacement of the two-plate structure during the movement.

[0043] In practical applications, it is sometimes necessary to adjust the guide pillars to accommodate different mold sizes and die-casting requirements. Based on these needs, a separate drive assembly is often required in the die-casting machine specifically for driving the guide pillars to complete the insertion and withdrawal action. This increases the structural complexity of the die-casting machine, leading to higher manufacturing and assembly costs.

[0044] To address the aforementioned issues, this invention provides a guide post extraction structure. This structure utilizes a clutch mechanism to connect and separate the drive assembly from the guide post and the two-plate structure. During normal operation, the drive assembly moves the two-plate structure relative to the guide post to complete the mold opening and closing operation. Furthermore, when adjustment of the guide post is required, the drive assembly moves the guide post relative to the two-plate structure to complete the extraction and insertion of the guide post.

[0045] Please see Figures 1 to 3 The guide column structure of the two-plate die casting machine provided by this utility model acts on the removable guide column 7. The removable guide column 7 is slidably inserted into the two-plate structure 4. The guide column structure includes a rear locking cylinder 1, a locking block 2 and a clutch assembly 3. The rear locking cylinder 1 is used to drive the locking block 2 to engage the removable guide column 7.

[0046] The clutch assembly 3 includes a locking member 31 and a locking seat 32. The locking member 31 is fixed to the locking block 2, and the locking seat 32 is fixed to the two-plate structure 4. When the locking block 2 is separated from the removable guide post 7, the locking member 31 and the locking seat 32 are fixedly connected.

[0047] In this embodiment, the removable guide post 7 can be slidably inserted into the two-plate structure 4 along the first path, wherein the first path can refer to the movement path of the two-plate structure 4 when performing mold opening and closing operations.

[0048] The cylinder body of the rear locking cylinder 1 can be mounted on a drive assembly, which may include a hydraulic drive device and a matching transmission mechanism and connecting structure. The piston rod of the rear locking cylinder 1 is connected to the locking block 2. Through the extension and retraction movement of the piston rod of the rear locking cylinder 1, the locking block 2 can be driven to move radially closer to or further away from the removable guide post 7, thereby achieving the fixing and separation between the locking block 2 and the removable guide post 7. The locking block 2 can be fixed to the removable guide post 7 by means of clamping, snapping, pin connection, magnetic attraction, etc., which are not limited here.

[0049] One end of the locking member 31 can be fixed to the locking block 2 by means of threaded connection, welding, snap-fit ​​connection, etc.; the other end of the locking member 31 can be provided with a detachable connection structure such as a magnetic component or a snap-fit ​​structure. The locking seat 32 can be provided with a matching structure that is compatible with the above-mentioned detachable connection structure, so as to ensure that when the other end of the locking member 31 moves to the preset position, it can be connected and fixed to the locking seat 32 by means of detachable connection such as magnetic attraction or snap-fit ​​connection, and can also ensure that the locking member 31 can be separated from the locking seat 32 under the action of external force.

[0050] Based on the above settings, the specific working process of the guide column structure in this embodiment is as follows:

[0051] When the removable guide post 7 needs to be adjusted by insertion and withdrawal, the rear locking cylinder 1 drives the locking block 2 to fix the removable guide post 7. At this time, the fastening part 31 on the locking block 2 and the fastening seat 32 on the two-plate structure 4 are separated. The driving component can drive the rear locking cylinder 1 and the locking block 2 to move along the first path (i.e. the mold opening and closing path), thereby driving the removable guide post 7 fixed on the locking block 2 to move axially relative to the two-plate structure 4. In this way, the position adjustment of the removable guide post 7 relative to the two-plate structure 4 can be realized, and the two-plate structure 4 will not be accidentally moved.

[0052] After the removable guide post 7 is adjusted, the rear locking cylinder 1 drives the locking block 2 to separate from the removable guide post 7. At this time, the fixing member 31 moves with the locking block 2 to the preset position and is fixed with the fixing seat 32. Then the drive assembly can drive the rear locking cylinder 1, the locking block 2, and the fixing member 31 to move along the first path (i.e. the mold opening and closing path). Thus, the two-plate structure 4 can be moved relative to the removable guide post 7 along the first path through the cooperation of the fixing member 31 and the fixing seat 32. In this way, the mold opening and closing operation of the two-plate structure 4 can be realized, and the removable guide post 7 will not be moved by mistake.

[0053] Therefore, the guide column structure provided in this embodiment adds a clutch assembly 3 between the two-plate structure 4 and the removable guide column 7. The clutch assembly 3 includes a locking member 31 disposed on the locking block 2 and a locking seat 32 disposed on the two-plate structure 4. When the locking block 2 is fixed to the removable guide column 7, the locking member 31 and the locking seat 32 are in a separated state. At this time, the removable guide column 7 can be moved independently by the drive assembly to complete the insertion and removal adjustment operation. When the locking block 2 is separated from the removable guide column 7, the locking member 31 and the locking seat 32 are in a fixed state. At this time, the two-plate structure 4 can be moved independently by the aforementioned drive assembly to complete the mold opening and closing operation. This solution utilizes the switching function of the simple clutch assembly 3 to selectively transmit the power provided by the drive assembly to the two-plate structure 4 or the removable guide column 7 according to the usage needs. In this way, a single drive assembly can be used to drive both the two-plate structure 4 and the removable guide column 7, thereby reducing the overall structural complexity of the two-plate die-casting machine and reducing manufacturing and assembly costs.

[0054] In one embodiment, refer to Figures 1 to 8 When the locking block 2 engages with the removable guide post 7, the pull rod cylinder drives the removable guide post 7 to slide, so that the locking member 31 separates from the locking seat 32.

[0055] In this embodiment, when the removable guide post 7 needs to be adjusted by insertion and withdrawal, the rear locking cylinder 1 drives the locking block 2 to fix the removable guide post 7. At this time, the fastening member 31 on the locking block 2 and the fastening seat 32 on the two-plate structure 4 are in a semi-separated state. The pull rod cylinder can drive the rear locking cylinder 1 and the locking block 2 to move along the first path (i.e. the mold opening and closing path), thereby driving the removable guide post 7 fixed on the locking block 2 to move axially relative to the two-plate structure 4. At the same time, it can drive the fastening member 31 and the fastening seat 32 to completely separate. In this way, the position adjustment of the removable guide post 7 relative to the two-plate structure 4 can be realized, and the two-plate structure 4 will not be accidentally moved.

[0056] In one embodiment, refer to Figures 1 to 8 The locking seat 32 is provided with a groove 321, and the locking member 31 includes a pin 312. When the locking member 31 is fixedly connected to the locking seat 32, the pin 312 is inserted into the groove 321. When the locking member 31 is separated from the locking seat 32, the pin 312 is disengaged from the groove 321.

[0057] In one embodiment, refer to Figures 1 to 8 The groove includes a first groove segment 3211 and a second groove segment 3212, which are bent and connected. The second groove segment 3212 includes a slot structure for locking the pin 312.

[0058] In this embodiment, the first groove segment 3211 and the second groove segment 3212 form an "L" shaped structure, and the end of the first groove segment 3211 facing away from the second groove segment 3212 passes through the locking seat 32. The locking member 31 is configured as a pin 312 that can slide in the groove 321 and engage with the groove 321.

[0059] like Figures 1 to 8 As shown, taking the extension direction of the first groove segment 3211 as the Y-axis direction and the extension direction of the second groove segment 3212 as the Z-axis direction as an example, during the process of the rear locking cylinder 1 driving the locking block 2 to fix the removable guide post 7, the locking member 31 moves along the Y-axis with the locking block 2 and enters the first groove segment 3211 from the second groove segment 3212; refer to Figure 2 When the locking block 2 and the removable guide post 7 are fixed in place, as follows: Figure 6 and Figure 7 As shown, the locking member 31 is located at the junction of the first groove segment 3211 and the second groove segment 3212; the subsequent drive assembly drives the removable guide post 7 fixed on the locking block 2 to move along the positive Z-axis to perform the guide post retraction operation, and the locking member 31 will simultaneously move along the positive Z-axis and disengage from the locking seat 32. After the guide post retraction operation is completed, the drive assembly drives the locking member 31 to move in the reverse Z-axis so that the locking member 31 re-enters the first groove segment 3211; when the locking member 31 moves along the first groove segment 3211 to the junction of the first groove segment 3211 and the second groove segment 3212, the rear locking cylinder 1 drives the locking block 2 to separate from the removable guide post 7, as shown. Figure 6 and Figure 8 As shown, at this time, the locking member 31 will move along the Y-axis with the locking block 2 and completely enter the second groove 3212, thereby locking the pin 312 into the second groove 3212. Due to the limiting effect of the second groove 3212 on the pin 312, the pin 312, which is locked into the second groove 3212, will not be able to move relative to the locking seat 32 along the Z-axis. That is, at this time, the locking member 31 and the locking seat 32 are mutually fixed on the Z-axis. See the specific reference. Figure 3 This achieves mutual fixation between the drive component and the two-plate structure 4 on the Z-axis. At this time, the drive component can drive the two-plate structure 4 to move along the Z-axis to complete the mold opening and closing operation.

[0060] Based on the above settings, before the retaining member 31 enters the second slot 3212, the first slot 3211 can first play a certain role in position correction and guidance of the retaining member 31, which can avoid the problem that the retaining member 31 cannot smoothly enter the second slot 3212 due to excessive positional deviation on the Y axis, and ensure that the drive assembly can smoothly re-connect with the two-plate structure 4 after completing the guide post insertion and removal operation.

[0061] In one embodiment, refer to Figures 1 to 5 The width of the first groove segment 3211 is greater than the width of the second groove segment 3212.

[0062] Specifically, the locking member 31 has a large positional deviation before entering the first slot 3211 from the outside. By appropriately increasing the width of the first slot 3211, it can be ensured that the locking member 31 can smoothly enter the first slot 3211. By appropriately reducing the width of the second slot 3212, after the locking member 31 is engaged in the second slot 3212, the problem of relative wobbling of the two-plate structure 4 due to excessive gap between the locking member 31 and the second slot 3212 can be avoided, thereby improving the accuracy of the drive assembly in moving the two-plate structure 4.

[0063] In one embodiment, refer to Figures 1 to 5 A transition structure 3213 is provided at the turning point between the first groove segment 3211 and the second groove segment 3212. The transition structure 3213 includes a chamfered portion and / or a rounded corner portion.

[0064] In this embodiment, the sharp corner portion at the transition point between the first groove segment 3211 and the second groove segment 3212 is set as a transition structure 3213. This allows the fastener 31 to move smoothly between the first groove segment 3211 and the second groove segment 3212 via the transition structure 3213, preventing the fastener 31 from being blocked by the sharp corner portion and causing jamming. The transition structure 3213 can be a chamfered portion, a rounded corner portion, or both (i.e., when the transition structure 3213 is a chamfered portion, a rounded corner portion is provided at the transition point of the chamfered portion). No limitation is made here.

[0065] In one embodiment, refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 The fastener 31 also includes a roller 311, which is rotatably disposed on the outer periphery of the end of the pin 312 and slides in the groove 321.

[0066] In this embodiment, by setting the roller 311, the sliding fit between the pin 312 and the groove 321 can be changed to a rolling fit, thereby reducing the friction between the pin 312 and the groove 321 and improving the smoothness of the pin 312 moving in the groove 321.

[0067] In one embodiment, refer to Figures 1 to 3 The guide post structure includes at least two rear locking cylinders 1 and at least two locking blocks 2; the at least two locking blocks 2 are arranged at intervals along the circumference of the retractable guide post 7, and the at least two rear locking cylinders 1 are connected to the at least two locking blocks 2 in a one-to-one correspondence.

[0068] At least two rear locking cylinders 1 are used to drive the corresponding locking blocks 2 to press against the teeth of the removable guide post 7 in order to engage and fix the removable guide post 7.

[0069] By setting at least two locking blocks 2 arranged circumferentially along the removable guide post 7, when the rear locking cylinder 1 drives the corresponding locking block 2 to move radially along the removable guide post 7, each locking block 2 can abut against the teeth of the removable guide post 7 from at least two different directions, thereby forming a clamping effect on the removable guide post 7, and the removable guide post 7 can be fixed by using this clamping effect. This clamping fixing method can conveniently realize the connection and fixation between the locking block 2 and the removable guide post 7 without setting a corresponding connection structure on the surface of the removable guide post 7, and can better adapt to removable guide posts 7 of different sizes and specifications, with high application flexibility.

[0070] Understandably, when there are at least two rear locking cylinders 1 and at least two locking blocks 2, the locking element 31 and locking seat 32 can also be set to at least two and correspond one-to-one with each locking block 2, which will not be elaborated here.

[0071] In one embodiment, refer to Figure 2 , Figure 3 and Figure 9 The locking block 2 has an arc-shaped pressing part 21, which is used to engage with the teeth of the removable guide post 7.

[0072] Specifically, the arc-shaped pressing part 21 can be well adapted to the cross-sectional shape of the removable guide post 7, increasing the contact area between the locking block 2 and the teeth of the removable guide post 7, thereby forming a better clamping effect on the removable guide post 7, and further improving the connection stability between the locking block 2 and the removable guide post 7.

[0073] This utility model embodiment also provides a two-plate die-casting machine, please refer to [link / reference]. Figures 1 to 3 The two-plate die-casting machine includes a removable guide column 7, a two-plate structure 4, a connecting frame 5, and the removable guide column structure in any of the above embodiments;

[0074] The removable guide post 7 is slidably inserted into the two-plate structure 4, and the fixing seat 32 is fixed to the two-plate structure 4; the rear locking cylinder 1 is set on the connecting frame 5, and the rear locking cylinder 1 is used to drive the locking block 2 to engage the removable guide post 7.

[0075] When the locking block 2 is separated from the removable guide post 7, the locking member 31 and the locking seat 32 are fixedly connected to lock the connecting frame 5 and the two-plate structure 4 together.

[0076] In this embodiment, the removable guide post 7 can be slidably inserted into the two-plate structure 4 along the first path, wherein the first path can refer to the movement path of the two-plate structure 4 when performing mold opening and closing operations.

[0077] The cylinder body of the rear locking cylinder 1 is fixed on the connecting frame 5, which is connected to a drive assembly. This drive assembly may include a hydraulic drive device and a matching transmission mechanism and connecting structure. The piston rod of the rear locking cylinder 1 is connected to the locking block 2. Through the extension and retraction of the piston rod of the rear locking cylinder 1, the locking block 2 can be driven to move radially closer to or further away from the removable guide post 7, thereby achieving the fixing and separation between the locking block 2 and the removable guide post 7. The locking block 2 can be fixed to the removable guide post 7 by means of clamping, snapping, pin connection, magnetic attraction, etc., which are not limited here.

[0078] One end of the locking member 31 can be fixed to the locking block 2 by means of threaded connection, welding, snap-fit ​​connection, etc.; the other end of the locking member 31 can be provided with a detachable connection structure such as a magnetic component or a snap-fit ​​structure. The locking seat 32 can be provided with a matching structure that is compatible with the above-mentioned detachable connection structure, so as to ensure that when the other end of the locking member 31 moves to the preset position, it can be connected and fixed to the locking seat 32 by means of detachable connection such as magnetic attraction or snap-fit ​​connection, and can also ensure that the locking member 31 can be separated from the locking seat 32 under the action of external force.

[0079] Based on the above settings, the specific working process of this two-plate die-casting machine is as follows:

[0080] When the removable guide post 7 needs to be adjusted by insertion or removal, the rear locking cylinder 1 drives the locking block 2 to fix the removable guide post 7. At this time, the fastening part 31 on the locking block 2 and the fastening seat 32 on the two-plate structure 4 are separated. The driving component can drive the connecting frame 5 to move along the first path (i.e. the mold opening and closing path). Thus, the removable guide post 7 fixed on the locking block 2 can be moved axially relative to the two-plate structure 4 through the connecting frame 5. In this way, the position adjustment of the removable guide post 7 relative to the two-plate structure 4 can be realized, and the two-plate structure 4 will not be accidentally moved.

[0081] After the removable guide post 7 is inserted and adjusted, the rear locking cylinder 1 drives the locking block 2 to separate from the removable guide post 7. At this time, the fastening member 31 moves with the locking block 2 to the preset position and is fixed with the fastening seat 32. Then the driving component can drive the connecting frame 5 to move along the first path (i.e. the mold opening and closing path). Thus, the two-plate structure 4 can be moved relative to the removable guide post 7 along the first path through the cooperation of the fastening member 31 and the fastening seat 32. In this way, the mold opening and closing operation of the two-plate structure 4 can be realized, and the removable guide post 7 will not be moved by mistake.

[0082] For other specific structures of the guide column structure, please refer to the above embodiments. Since this two-plate die-casting machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments. That is, by utilizing the switching action of the simple clutch component 3, the power provided by the drive component can be selectively transmitted to the two-plate structure 4 or the removable guide column 7 according to the usage needs. In this way, the drive of the two-plate structure 4 and the removable guide column 7 can be realized by using one drive component, thereby reducing the overall structural complexity of the two-plate die-casting machine and reducing manufacturing and assembly costs.

[0083] Preferably, refer to Figures 1 to 3 The connecting frame 5 has a sleeve structure 51, which is sleeved on the removable guide post 7, thereby improving the structural compatibility between the connecting frame 5 and the removable guide post 7; and during the process of the driving component driving the two-plate structure 4 to move through the connecting frame 5, the removable guide post 7 can provide better axial limiting and guiding effect for the connecting frame 5.

[0084] In one embodiment, refer to Figures 1 to 8 The fastening element 31 includes a pin 312; the fastening seat 32 is provided with a groove 321, the groove 321 includes a first groove segment 3211 and a second groove segment 3212, the first groove segment 3211 and the second groove segment 3212 are bent and connected.

[0085] When the locking member 31 is fixedly connected to the locking seat 32, the pin 312 is engaged in the slot structure of the second slot section 3212; when the locking member 31 is separated from the locking seat 32, the pin 312 is disengaged from the slot structure of the second slot section 3212.

[0086] In this embodiment, the first groove segment 3211 and the second groove segment 3212 form an "L" shaped structure, and the end of the first groove segment 3211 facing away from the second groove segment 3212 passes through the locking seat 32. The locking member 31 is configured as a pin 312 that can slide in the groove 321 and engage with the groove 321.

[0087] like Figures 1 to 8 As shown, taking the extension direction of the first groove segment 3211 as the Y-axis direction and the extension direction of the second groove segment 3212 as the Z-axis direction as an example, during the process of the rear locking cylinder 1 driving the locking block 2 to fix the removable guide post 7, the locking member 31 moves along the Y-axis with the locking block 2 and enters the first groove segment 3211 from the second groove segment 3212; refer to Figure 2 When the locking block 2 and the removable guide post 7 are fixed in place, as follows: Figure 6 and Figure 7As shown, the locking member 31 is located at the junction of the first groove segment 3211 and the second groove segment 3212. The subsequent drive assembly drives the connecting frame 5 to move along the positive Z-axis, thereby causing the removable guide post 7 fixed on the locking block 2 to move along the positive Z-axis to perform a guide post retraction operation. Simultaneously, the locking member 31 will move along the positive Z-axis and disengage from the locking seat 32. After completing the guide post retraction operation, the drive assembly drives the connecting frame 5 to move in the reverse Z-axis, causing the locking member 31 to move in the reverse Z-axis and re-enter the first groove segment 3211. When the locking member 31 moves along the first groove segment 3211 to the junction of the first groove segment 3211 and the second groove segment 3212, the rear locking cylinder 1 drives the locking block 2 to separate from the removable guide post 7, as shown. Figure 6 and Figure 8 As shown, at this time, the locking member 31 will move along the Y-axis with the locking block 2 and completely enter the second groove 3212, thereby locking the pin 312 into the second groove 3212. Due to the limiting effect of the second groove 3212 on the pin 312, the pin 312, which is locked into the second groove 3212, will not be able to move relative to the locking seat 32 along the Z-axis. That is, at this time, the locking member 31 and the locking seat 32 are mutually fixed on the Z-axis. See the specific reference. Figure 3 This achieves mutual fixation between the connecting frame 5 and the two-plate structure 4 on the Z-axis. At this time, the driving component can drive the connecting frame 5 to move the two-plate structure 4 along the Z-axis to complete the mold opening and closing operation.

[0088] In one embodiment, refer to Figures 1 to 3 The two-plate die-casting machine also includes a positioning pin 6, which is located on the side of the two-plate structure 4 facing the connecting frame 5; the connecting frame 5 is provided with a positioning hole 52, and the positioning pin 6 is slidably inserted into the positioning hole 52.

[0089] As illustrated, the engagement between the positioning pin 6 and the positioning hole 52 can limit the position of the two-plate structure 4 on the X and Y axes, thereby improving the relative positional stability between the two-plate structure 4 and the connecting frame 5 and reducing the probability of the two-plate structure 4 shifting position relative to the connecting frame 5 during movement.

[0090] It should be noted that the guide column structure disclosed in this utility model and other contents of the two-plate die-casting machine can be found in the prior art, and will not be repeated here.

[0091] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
