TECHNICAL FIELD

[0001] The utility model relates to the technical field of die casting machine accessories, and particularly relates to a template guide column limiting device and die casting machine. BACKGROUND

[0002] Die casting machine is one of the important equipment for processing and producing metal workpieces in modern industry. The common die casting machine is three-plate type, three plates are rear lock plate, middle movable plate and front fixed plate, and four guide columns are connected in series through the guide holes of the three plates. The front fixed plate is fixed, and the middle movable plate can slide forward and backward along the guide column under the driving of the oil cylinder of the motor on the rear lock plate.

[0003] The guide column is not completely fixed, for example, the guide column needs to be controlled during mold adjustment, so the guide column needs to be limited. In the existing limiting device, the part shape is complex, the processing cost is high, and the rigid connection between the template guide column limiting sliding baffle and the template guide column limiting oil cylinder makes the disassembly process difficult for workshop workers.

[0004] Therefore, the template guide column limiting device is optimized, which can reduce the material and processing cost on the basis of the original, facilitate the disassembly of workers, improve safety, and be universal for various machine types. CONTENT OF THE UTILITY MODEL

[0005] The utility model provides a template guide column limiting device and die casting machine, the part appearance of template guide column limiting device is as simple as possible, easy to process, reduces the cost of material and processing. The T-shaped groove is arranged between the sliding baffle and the driver for non-rigid connection (flexible connection), which facilitates the disassembly of workers. If an accident occurs when the sliding baffle limits or releases the guide column, violent collision can be avoided. Moreover, the T-shaped groove in the sliding baffle of various machine types can be processed into the same size, so that the driver can be universal between different machine types as long as the required driving stroke of the driver is the same, which improves the universality of parts and facilitates material procurement and management.

[0006] A template guide column limiting device designed for this purpose includes a sliding baffle that cooperates with a guide column nut to limit the guide column, and a driver that provides limiting power to the sliding baffle.

[0007] The output end of the driver is flexibly connected with the sliding baffle.

[0008] The sliding baffle moves towards the direction of clamping the guide column nut in the starting state of the driver, and the sliding baffle moves to the position of clamping the guide column nut, so that the sliding baffle cooperates with the guide column nut and achieves the purpose of limiting the guide column.

[0009] The template guide pillar limiting device further comprises a limiting base, the sliding baffle is slidably connected with the limiting base, the limiting base is provided with a clamping empty cavity corresponding to the sliding baffle and the guide pillar nut, and the sliding baffle clamps the guide pillar nut through the clamping empty cavity.

[0010] The limiting base is provided with a sliding groove, the sliding baffle is arranged on the sliding groove of the limiting base, and the sliding baffle is slidably connected with the sliding groove.

[0011] The sliding baffle is provided with an oil groove for filling a lubricating medium, and the sliding baffle is lubricated by the lubricating medium during sliding on the limiting base.

[0012] The limiting base is provided with an opening forming the sliding groove, the limiting base is provided with a cover plate above the opening, and the sliding baffle is arranged between the cover plate and the sliding groove of the limiting base in an up-down limiting manner.

[0013] The limiting base is provided with a limiting plate corresponding to the outer side of the sliding groove, and the sliding baffle is arranged between the limiting plate and the empty cavity of the limiting base in a front-rear limiting manner through the limiting plate.

[0014] The driver is arranged on the limiting plate, and the output end of the driver penetrates through the limiting plate and is flexibly connected with the sliding baffle.

[0015] The output end of the driver is provided with a connecting end, the sliding baffle is provided with a connecting groove portion matched with the connecting end, the connecting end is embeddedly arranged on the connecting groove portion, the connecting end and the connecting groove portion are matched in a T shape in a top view direction, and the output end of the driver is flexibly connected with the sliding baffle through the matching between the connecting end and the connecting groove portion.

[0016] A die casting machine comprises a rear locking template, the rear locking template is provided with a guide hole matched with a guide pillar, a guide pillar nut is sleeved on the outer side of the guide pillar, the guide pillar nut limits the front and back movement of the guide pillar relative to the rear locking template within a corresponding distance, and the rear locking template is provided with the template guide pillar limiting device.

[0017] The guide hole of the rear locking template is provided with a guide sleeve, the guide pillar penetrates through the guide hole and the guide sleeve and is matched with the axial center of the guide hole of the rear locking template.

[0018] The beneficial technical effects of the utility model are as follows:

[0019] The T-shaped groove (connecting groove) of the sliding baffle and the T-shaped round end (connecting end) of the piston rod of the driver cooperate to form a non-rigid connection with only axial constraint of the piston rod. The advantage of this connection is that it is more convenient for workshop workers to assemble and disassemble compared to a rigid connection. Furthermore, in the event of an operational malfunction of the template guide column limiting device during machine operation, if the sliding baffle is jammed or loosened and the guide column fails to move to the designated position, causing a collision between the guide column and the sliding baffle, the non-rigid connection allows the sliding baffle to shift or deform in the normal direction of the piston rod, thus avoiding severe impact damage to the template guide column caused by a rigid connection. This connection method not only reduces the manpower and time spent by workers during machine assembly but also reduces losses caused by machine malfunctions, ensuring safety to a certain extent. Moreover, the T-shaped groove in the sliding baffle of each model can be machined to the same size. This means that as long as the required drive stroke of the driver is the same, the drivers between different models can be interchanged, improving the versatility of parts and facilitating material procurement and management.
