Description

Technical Field

[0001] This utility model relates to the field of die-casting equipment technology, and in particular to an auxiliary support slider for a three-plate mold supported by the guide column of a die-casting equipment. Background Technology

[0002] Currently, in die casting processes, simple two-plate molds cannot meet the production needs of some products, hence the emergence of three-plate mold designs.

[0003] Please refer to the instruction manual appendix. Figure 1 In the existing three-plate die casting process, the fixed mold A plate 201, the fixed mold B plate 202 and the moving mold plate 203 are installed side by side on the inside of the four tie rods 204 of the die casting mold component 200. Under the guidance of the tie rods 204, the die casting mold component 200 can push the moving mold plate 203 and the fixed mold B plate 202 to press onto the fixed mold A plate 201, thereby completing the mold pressing.

[0004] However, as the product volume increases, the mold size also increases accordingly. The existing mold relies solely on four guide pillars 2011 on the fixed mold A plate 201 to support the weight of the fixed mold B plate 202. This guide pillar 2011 support structure is only suitable for small three-plate molds. When the die-casting machine tonnage reaches 2000T or more, the mold weight will increase significantly. At this time, the four guide pillars 2011 alone are insufficient to stably support the weight of the fixed mold B plate 202, which can easily lead to wear or even deformation of the guide pillars 2011 on the fixed mold A plate 201 during use, resulting in jamming of the fixed mold B plate 202 during opening and closing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a three-plate mold auxiliary support slider supported by the gateposts of a die-casting equipment, thereby overcoming the deficiencies in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A three-plate mold auxiliary support slider supported by a die-casting equipment guide column includes a slider body; the first end of the slider body has a protruding mounting boss; a support slope is connected between the mounting boss and the top of the slider body, the support slope corresponds to the slope on the fixed mold B plate, and is used to support the fixed mold B plate. The bottom of the slider body has an arc-shaped groove, which corresponds to the original tie bars of the die-casting mold component, so that the slider body can slide on the tie bars.

[0007] Furthermore, a lubricating block is embedded in the arc-shaped groove, the lubricating block having an arc-shaped bottom surface flush with the arc-shaped groove, and a mesh lubrication groove is provided on the bottom surface of the lubricating block.

[0008] Furthermore, a first oil passage is vertically arranged inside the lubricating block, which is connected to the oil outlet on the bottom surface of the lubricating block, and lubricating oil is permeated into the mesh lubrication groove through the oil outlet.

[0009] Furthermore, the slider body also has a built-in second oil passage connected to the first oil passage. The second oil passage is connected to the oil inlet on the second end face of the slider body, so that the lubricating oil pumped in from the external oil supply device flows sequentially through the oil inlet, the second oil passage, the first oil passage, and the oil outlet, and then permeates into the mesh lubrication groove through the oil outlet.

[0010] Preferably, the first end of the slider body is further provided with a clearance groove, which is arranged along the direction in which the mounting boss and the supporting inclined surface meet.

[0011] Furthermore, the top of the mounting boss is provided with a stepped protrusion, and several mounting holes are also vertically opened on the mounting boss.

[0012] Preferably, the slider body also has a weight-reducing cutout.

[0013] Preferably, two lubricating blocks are provided, which are embedded side by side at intervals in the arc-shaped groove at the bottom of the slider body. At the same time, two sets of the second oil passage and the oil outlet are also provided, corresponding to the two lubricating blocks.

[0014] Preferably, the lubricating block is fixed to the slider body by fasteners.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1) The auxiliary support slider of the three-plate mold supported by the gatepost of the die-casting equipment in this case shares the load of the fixed mold plate A on the fixed mold plate B by setting the support slider on the original gatepost of the die-casting mold component. By setting the lubricating block at the bottom of the support slider and pumping in lubricating oil, the sliding friction of the support slider on the gatepost is reduced, which effectively solves the problem of insufficient load of the fixed mold plate A on the fixed mold plate B during large-tonnage die casting, which leads to deformation of the fixed mold plate A and jamming of the mold opening and closing.

[0016] 2) The auxiliary support slider of the three-plate mold supported by the guide column of the die-casting equipment in this case can reduce the load of the guide column of the fixed mold A plate by more than 50% after testing, effectively avoid wear and deformation of the guide column of the fixed mold A plate, and extend the overall service life of the mold by more than 30%.

[0017] 3) In this case, the three-plate mold auxiliary support slider is supported by the tie column of the die casting equipment. The external oil supply equipment is connected to the oil inlet through the pipeline, and the external oil supply equipment is linked with the die casting machine. It automatically lubricates the slider body according to the number of times the die casting machine opens and closes the mold, which reduces the friction coefficient between the slider body and the tie column by 40%, further ensuring that the opening and closing process of the fixed mold B plate is smooth and without jamming, and improving production stability. 4) The auxiliary support slider of the three-plate mold supported by the guide column of the die casting equipment in this case reduces the equipment cost, eliminates the need for frequent disassembly and assembly, shortens the production changeover time by 50%, and is suitable for the production needs of large three-plate molds of die casting machines with a tonnage of 1000T or more.

[0018] To provide a clearer understanding of this invention, the preferred embodiments of this invention will be described below in conjunction with the accompanying drawings. Attached Figure Description

It is installed in pairs on the original gateposts 204 of the die-casting mold components and supports the fixed mold plate B 202 of the mold from the bottom, thereby sharing the supporting force of the fixed mold plate A 201 on the fixed mold plate B 202, and avoiding the jamming phenomenon during the opening and closing of the mold due to the deformation of the fixed mold plate A 201 under heavy load during the die-casting process.

[0025] Please also refer to Figure 3-7The present invention provides a three-plate mold auxiliary support slider 100 supported by the gatepost of the die-casting equipment, including a slider body (1), the first end of the slider body (1) having a protruding mounting boss (2); a support inclined surface (3) is connected between the mounting boss (2) and the top of the slider body (1), the support inclined surface (3) corresponding to the inclined surface on the fixed mold B plate (202) for supporting the fixed mold B plate (202); the first end of the slider body (1) is also provided with a relief groove (4), the relief groove (4) is set along the direction where the mounting boss (2) and the support inclined surface (3) are connected; the top of the mounting boss (2) is provided with a stepped protrusion (21), and several mounting holes (22) are also vertically opened on the mounting boss (2), the mounting holes (22) are used to cooperate with bolts to install and fix the slider body (1) to the bottom of the fixed mold B plate (202), so that the slider body (1) can move together with the fixed mold B plate (202) during the die-casting process.

[0026] Furthermore, the bottom of the slider body (1) has an arc-shaped groove (5), which corresponds to the original golem column (204) of the die-casting mold component, so that the slider body (1) can slide on the golem column (204).

[0027] Furthermore, a lubricating block (6) is embedded in the arc-shaped groove (5). The lubricating block (6) is fixed to the slider body (1) by fasteners. The lubricating block (6) has an arc-shaped bottom surface that is flush with the arc-shaped groove (5). A mesh lubricating groove (61) is provided on the bottom surface of the lubricating block (6). A first oil passage (62) is vertically provided in the lubricating block (6). The first oil passage (62) is connected to the oil outlet (63) on the bottom surface of the lubricating block (6). The lubricating oil is penetrated into the mesh lubricating groove (61) through the oil outlet (63), so that the lubricating oil evenly covers the contact surface between the slider body (1) and the guide post (204), ensuring that the slider body (1) slides stably on the guide post (204).

[0028] Furthermore, the slider body (1) also has a built-in second oil passage (64) that is connected to the first oil passage (62). The second oil passage (64) is connected to the oil inlet (65) on the second end face of the slider body (1), so that the lubricating oil pumped in from the external oil supply device flows through the oil inlet (65), the second oil passage (64), the first oil passage (62), and the oil outlet (63) in sequence, and then permeates into the mesh lubrication groove (61) through the oil outlet (63), thereby ensuring that the slider body (1) can slide smoothly on the guide pillar (204) along with the fixed mold plate B (202).

[0029] It should be noted that the external oil supply device in this case is connected to the oil inlet (65) through a pipeline, and the external oil supply device is linked with the die casting machine. It automatically lubricates the slider body (1) according to the number of times the die casting machine opens and closes the mold, and finally realizes the smooth sliding between the slider body (1) and the guide column (204), ensuring the normal opening and closing of the fixed mold plate B (202).

[0030] As a preferred embodiment, the slider body (1) is also provided with a weight-reducing hollow (11) to reduce the overall weight of the slider body (1) and ensure the stability of operation.

[0031] As a preferred embodiment, in this embodiment, there are two lubricating blocks (6). The two lubricating blocks (6) are spaced apart and embedded side by side in the arc-shaped groove (5) at the bottom of the slider body (1). At the same time, the second oil passage (64) and the oil outlet (63) are also provided with two sets corresponding to the two lubricating blocks (6), thereby playing a redundant role and further ensuring the stability of the slider body operation.

[0032] Preferably, in this embodiment, the lubricating block (6) is made of brass.

[0033] Compared to existing technologies, the auxiliary support slider of the three-plate mold supported by the gatepost of the die-casting equipment in this case shares the load of the fixed mold plate A on the fixed mold plate B by setting the support slider on the original gatepost of the die-casting mold components. By setting the lubricating block at the bottom of the support slider and pumping in lubricating oil, the sliding friction of the support slider on the gatepost is reduced. This effectively solves the problem of insufficient load-bearing capacity of the fixed mold plate A on the fixed mold plate B during large-tonnage die casting, which leads to deformation of the fixed mold plate A and jamming of the mold opening and closing.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
