Description

Technical Field

[0001] The utility model relates to the technical field of die-casting machines, in particular to a moving template support and guiding mechanism of a die-casting machine. Background Art

[0002] A die-casting machine is a machine used for pressure casting. It includes two types: a hot chamber and a cold chamber. The latter is further divided into two types: vertical and horizontal. Under pressure, the die-casting machine hydraulically injects molten metal into a mold for cooling and forming. After the mold is opened, a solid metal casting can be obtained. It was initially used for die-casting type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and household appliances, die-casting technology has developed extremely rapidly.

[0003] The existing patent with the publication number CN209334695U discloses a moving template support and guiding mechanism for a die-casting machine, including a moving template (1). On both sides of the lower part of the moving template (1), chutes (3) for embedding linear guide rails (2) are symmetrically arranged. The top of the linear guide rail (2) is in contact with the bottom of the chute (3) so that the moving template (1) can move linearly along the extension direction of the linear guide rail (2). The cross-section of any linear guide rail (2) is in an inverted L shape, and the outer part of the cross-section of the chute (3) is in an anti-L shape. An installation groove (4) is dug in the vertical part of the anti-L-shaped cross-section. A bearing seat (5) with a bearing (6) is installed in the installation groove (4), and the inner side wall of the bearing (6) is in rolling contact with the outer side wall of the horizontal part of the linear guide rail (2) to reduce the frictional resistance. The utility model conducts support and guidance through the setting of a linear guide rail and a bearing structure, so that the inner side surface of the moving template has rolling friction with the linear guide rail to adjust the frictional force between the two.

[0004] The existing die-casting machine includes a stationary template and a moving template. The moving template moves through a guide rail and is combined with the stationary template for die-casting. However, since the moving template will wear when moving on the guide rail surface for a long time, it needs to be maintained regularly to extend the service life of the die-casting machine. For this reason, we propose a moving template support and guiding mechanism of a die-casting machine to solve the above-mentioned problems. Summary of the Utility Model

[0005] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract and title of the utility model of the present application, to avoid obscuring the purpose of this part, the abstract, and the title. Such simplifications or omissions shall not be used to limit the scope of the utility model.

[0006] Therefore, the purpose of the present utility model is to provide a moving template support and guiding mechanism for a die-casting machine, which can solve the problem that the existing die-casting machine includes a static template and a moving template. The moving template moves through a guide rail and is combined with the static template for die-casting. However, since the moving template will be worn when moving on the surface of the guide rail for a long time, it needs to be maintained regularly to extend the service life of the die-casting machine.

[0007] To solve the above technical problems, the present utility model provides a moving template support and guiding mechanism for a die-casting machine, adopting the following technical solutions: including a support seat, two sliding rods are symmetrically and fixedly installed before and after between the inner side walls of both sides of the inner cavity of the support seat. There is a moving seat above the two sliding rods. Four insertion blocks are provided at the bottom of the moving seat. Each bottom of the insertion blocks is fixedly installed with an L-shaped connecting plate. A bidirectional lead screw is rotatably connected between the upper and lower inner side walls of the inner cavity of the connecting plate. The upper and lower two sections of the bidirectional lead screw are respectively threadedly movably connected with a sliding plate. One side of the two sliding plates close to each other is fixedly installed with a sliding sleeve through a fastening bolt. One side of the two sliding sleeves close to each other is attached to the outer wall of the sliding rod.

[0008] Optionally, a limiting plate is fixedly installed in the middle of the inner cavity of the connecting plate. The bidirectional lead screw penetrates the surface of the limiting plate, and the bidirectional lead screw is rotatably connected to the surface of the limiting plate.

[0009] Optionally, the bottom end of the bidirectional lead screw penetrates the bottom of the connecting plate, and a turning handle is fixedly installed at the bottom end of the bidirectional lead screw.

[0010] Optionally, an insertion plate is fixedly installed at the bottom of the moving seat. Each insertion plate is respectively located directly above the corresponding insertion block, and the insertion block is inserted into the bottom of the insertion plate.

[0011] Optionally, a housing is fixedly installed on the front side of the insertion plate. A limiting rod is inserted into the inner cavity of the housing. The rear end of the limiting rod is inserted between the insertion plate and the insertion block.

[0012] Optionally, a positioning plate is fixedly installed on the surface of the limiting rod. A telescopic spring is provided between the front side of the positioning plate and the inner side wall of the front side of the housing. The telescopic spring is sleeved outside the limiting rod. The front end of the limiting rod penetrates the front side of the housing, and a handle is fixedly installed at the front end of the limiting rod.

[0013] Optionally, two symmetrically arranged cylinders are fixedly installed in the inner cavity at the bottom of the moving seat. The output ends of the two cylinders at the bottom are fixedly connected with a push rod. A support foot is fixedly installed at the bottom of the push rod. The bottom of the support foot is adapted to the upper surface of the sliding rod.

[0014] In summary, the present utility model includes at least one of the following beneficial effects: 1. By providing a movable seat and multiple insertion blocks at the bottom of the movable seat, when maintenance is required for the sliding sleeve, the staff first rotates the turning handle, which drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the upper and lower slide plates to disengage from the surface of the slide rod. Subsequently, the staff pulls out the handle outward, and at this time, the insertion blocks can be disassembled from the insertion plate. The staff disassembles the fastening bolts to disassemble the sliding sleeve for maintenance, achieving rapid disassembly of the sliding sleeve, simple operation, and strong practicability.

[0015] 2. By providing cylinders, before disassembling the sliding sleeve, the staff first starts the two cylinders. After the cylinders are started, they drive the push rods on the surface to move. The push rods drive the bottom support feet to move downward. Subsequently, the support feet are pressed against the surface of the slide rod under the action of the push rods. At this time, the movable seat can be supported by the two support feet, and the staff can then disassemble the sliding sleeve, achieving support for the movable seat before disassembling the sliding sleeve, ensuring safety during disassembly, protecting the lives of the staff, and having strong practicability.

[0022] The following is combined with the attached Figures 1-4A further detailed description is given to the present utility model.

[0023] Embodiment 1. Referring to Figures 1-4 , in this embodiment, in order to solve the problem that in the existing die-casting machine, which includes a stationary template and a moving template, the moving template moves through guide rails and combines with the stationary template for die-casting. However, since the moving template will be worn when moving on the surface of the guide rails for a long time, it needs to be maintained regularly to extend the service life of the die-casting machine. The present utility model discloses a support and guiding mechanism for the moving template of a die-casting machine,

[0024] which includes a support base 1. Between the inner walls on both sides of the inner cavity of the support base 1, two slide bars 2 are symmetrically and fixedly installed before and after. Above the two slide bars 2, there is a moving seat 3. At the bottom of the moving seat 3, there are four insertion blocks 4. At the bottom of each insertion block 4, an L-shaped connecting plate 5 is fixedly installed. Between the upper and lower inner walls of the inner cavity of the connecting plate 5, a bidirectional lead screw 6 is rotatably connected. The upper and lower sections of the bidirectional lead screw 6 are respectively in threaded movable connection with slide plates 7. On the closer sides of the two slide plates 7, sliding sleeves 20 are fixedly installed through fastening bolts 8. On the closer sides of the two sliding sleeves 20, they are respectively attached to the outer wall of the slide bar 2.

[0025] In the middle of the inner cavity of the connecting plate 5, a limiting plate 9 is fixedly installed. The bidirectional lead screw 6 penetrates through the surface of the limiting plate 9, and the bidirectional lead screw 6 is rotatably connected to the surface of the limiting plate 9.

[0026] The bottom end of the bidirectional lead screw 6 penetrates through the bottom of the connecting plate 5, and a turning handle 10 is fixedly installed at the bottom end of the bidirectional lead screw 6.

[0027] At the bottom of the moving seat 3, an insertion plate 11 is fixedly installed. Each insertion plate 11 is respectively located directly above the corresponding insertion block 4, and the insertion block 4 is inserted at the bottom of the insertion plate 11.

[0028] At the front side of the insertion plate 11, a housing 12 is fixedly installed. A limiting rod 13 is inserted into the inner cavity of the housing 12. The rear end of the limiting rod 13 is inserted between the insertion plate 11 and the insertion block 4.

[0029] On the surface of the limiting rod 13, a positioning plate 14 is fixedly installed. Between the front side of the positioning plate 14 and the inner wall of the front side of the housing 12, a telescopic spring 15 is provided. The telescopic spring 15 is sleeved outside the limiting rod 13.

The bottom of the support foot 19 is adapted to the upper surface of the slide bar 2.

[0031] The specific working principle is as follows: First, before the staff disassembles the sliding sleeve 20, two cylinders 17 are started. After the cylinders 17 are started, they drive the surface push rod 18 to move. The push rod 18 drives the bottom support feet 19 to move downward. Subsequently, the support feet 19 are pressed against the surface of the sliding rod 2 under the action of the push rod 18. At this time, the moving seat 3 can be supported by the two support feet 19, and the staff can then disassemble the sliding sleeve 20. Subsequently, when the staff needs to maintain and repair the sliding sleeve 20, first turn the handle 10. The handle 10 drives the bidirectional lead screw 6 to rotate. The rotation of the bidirectional lead screw 6 drives the upper and lower slide plates 7 to disengage from the surface of the sliding rod 2. Then, the staff pulls the handle 16 outwards, and at this time, the plug block 4 can be disassembled from the plug board 11. The staff disassembles the fastening bolt 8, thereby disassembling the sliding sleeve 20 for maintenance.
