Description

Technical Field

[0001] The utility model relates to the technical field of die-casting machines, and particularly relates to a template for a large die-casting machine. Background Art

[0002] The essence of die-casting is to pour molten or semi-molten alloy into the pressure chamber of a die-casting machine, and then under the action of high pressure, it fills the cavity of the die-casting mold at an extremely high speed, and the molten alloy cools and solidifies under high pressure to form a high-efficiency and high-precision casting method. Most of the die-casting machine clamping structures are three-plate clamping structures, and the moving template and the rear template are provided with moving and docking guides through tie rods; as an important part of the clamping part of die-casting machines and injection molding machines, the moving template mainly plays the role of bearing the clamping force and installing the mold. At the same time, it must meet the requirements of small deformation, uniform stress, light weight, convenient casting processing, reasonable structure, etc. The design of the template must be highly emphasized in the design of the machine.

[0003] The advantages and disadvantages of the moving template directly affect the machine performance and cost. A light enough weight will directly save the machine a considerable amount of cost, but good rigidity must be ensured, otherwise it will affect the quality of the products during machine use. At the same time, a reasonable structure must be possessed to make the template stress evenly, avoiding excessive local stress, resulting in plastic deformation or even fracture of the template.

[0004] The Korean patent with the application number KR2020210047148 discloses a mold structure for rotor die-casting using a sliding template. The mold structure includes a first mold and a second mold. The first mold has an installation space for installing a rotor core, and the first mold also has an annular forming space; it also includes a plurality of mold plates, which are arranged at intervals with the first mold, and both the first mold and the second mold can slide towards the rotor core. The invention realizes the approach of the first mold and the second mold through the rotor core, thereby forming a mold in the annular cavity. When the first mold is pushed by the rotor core, it receives a force at the center, and the first mold slides under the constraint of the guide rail, resulting in uneven stress on the first mold and easily causing deformation of the first mold, affecting the formed mold. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a template for a large die-casting machine with high stability and low material consumption.

[0006] To solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A template of a large die-casting machine, comprising: a moving template and a rear template connected in series by guide rods. The moving template is evenly provided with channels capable of passing through the guide rods. The moving template includes cylinders configured with the channels, and the moving template further includes columns. The cylinders and the columns are both arranged on the side of the moving template close to the rear template, and the columns are evenly arranged on the side of the moving template. The moving template and the rear template can adjust the distance relative to the guide rods. Among them, the moving template is guided by the sliding of the guide rods relative to the channels, so as to increase the stability of the moving template during the distance adjustment process;

[0008] The cooperation between the evenly arranged cylinders and the guide rods provides guidance for the moving template at multiple positions, and can limit each other to ensure the displacement parallelism of the moving template, improving the die-closing accuracy; the multiple cylinders also disperse the load of the moving template on the guide rods, reducing the force on the guide rods and increasing the service life of the guide rods;

[0009] An oil cylinder is arranged on the rear template, and the telescopic end of the oil cylinder faces the column. The oil cylinder pushes out the moving template through telescoping. When the oil cylinder acts, the force at the output end of the oil cylinder acts on the column, and then is transmitted to the moving template through the column, and finally transmitted to the mold on the other side of the moving template. On the one hand, the force transmission path is extended through the arrangement of the column, reducing the interference received by the template. On the other hand, the evenly arranged columns can evenly transmit the acting force of the oil cylinder to the moving template, and the template is evenly stressed, avoiding the possibility of plastic deformation or even fracture of the template caused by excessive local stress, and improving the die-closing stability.

[0010] Preferably, the cylinder extends along the direction of the guide rod, and the channel penetrates through the cylinder. The cylinder along the extension direction of the guide rod forms a cooperation with the guide rod through the channel, increasing the contact surface between the moving template and the guide rod in the extension direction of the guide rod, thereby improving the stability of the moving template in the sliding direction, reducing the possibility of its jitter, and helping to improve the die-closing stability;

[0011] While the cylinder forms the guidance, it does not increase the overall thickness of the moving template, reducing the weight and consumables, and reducing the load on the guide rod and the manufacturing cost without affecting the performance.

[0012] Preferably, the cylinder is provided with an oil hole communicating the outside with the channel, the oil hole is arranged perpendicular to the channel, and an annular card slot is coaxially arranged in the channel. A ring body can be arranged in the card slot, and the ring body is arranged in cooperation with the guide rod and the inner wall of the channel to form an oil cavity for lubrication; at the same time, the ring body helps to block the particles attached to the guide rod from entering the through groove, preventing the particles from scratching the inner wall of the channel and causing wear of the moving template.

[0013] Preferably, the columns and the column bodies are arranged alternately, and reinforcing ribs are fixed between the column bodies and the adjacent columns. The reinforcing ribs form the connection between the columns and the column bodies, improving the stability of the connection between the columns and the column bodies and the moving template. At the same time, when the force of the oil cylinder acts on the columns, the columns can disperse the acting force to each column body through the reinforcing ribs. On the one hand, the interference is further reduced through the reinforcing ribs, improving the mold closing stability. On the other hand, the acting range of the acting force is expanded, improving the force balance of the mold, thereby further reducing the possibility of plastic deformation of the mold.

[0014] Preferably, there is a spacing distance between the reinforcing ribs and the side surface of the moving template where the column bodies are provided. The reinforcing ribs are fixed at the positions near the ends of the moving template and the columns to form an outer frame, which is beneficial to protecting the components arranged in the middle of the moving template and reducing the risk of being knocked and damaged during disassembly and assembly.

[0015] Preferably, the end of the column is provided with an inwardly recessed installation cavity, and the end of the column is provided with a hole body surrounding the outside of the installation cavity. The installation cavity can accommodate the telescopic end of the oil cylinder, realizing the guiding of the acting force, ensuring that the acting force directions of multiple oil cylinders are perpendicular to the moving template, reducing the possibility of the moving template tilting and shaking, improving the mold closing stability and accuracy, and at the same time reducing the interference between the through groove of the moving template and the guide rod; the setting of the hole body is used for installing the detection component to facilitate the monitoring and control of the die-casting action.

[0016] Preferably, the installation cavity has a guiding surface for movably connecting the plate body. The installation cavity is externally connected with an installation hole group for arranging the power component, and the power component is used for the plate body to slide on the guiding surface. The power component is connected to the outside of the column, and the driving end of the power component can make the plate body slide in the installation cavity. The guiding surface restricts the sliding direction of the plate body to lock the telescopic end of the oil cylinder on the specified path, so as to realize the fixation of the moving template and the rear template to achieve mold closing; the uniform arrangement of multiple columns also realizes the uniform distribution of the locking force to ensure the parallelism after the connection between the moving template and the fixed template, which helps to improve the synchronous movement stability of the two.

[0017] Preferably, the moving template is provided with a convex platform downward at the bottom, and the convex platform has an end surface perpendicular to the guide rod. The end surface is used to connect the moving die oil cylinder. After the moving template and the rear template form a locking connection, the moving die oil cylinder can make the moving template carry the rear template to slide axially along the guide rod for mold closing.

[0018] Preferably, multiple columns and multiple column bodies are arranged in a ring on one side of the moving template, and the columns and column bodies are close to the side edge of the moving template. Multiple columns, column bodies and reinforcing ribs form a ring frame, which is close to the edge of the moving template, providing a large installation and arrangement space for the middle part of the moving template and forming protection for the internal components.

[0019] The utility model has the following beneficial effects compared with the prior art: on the premise of reducing the thickness, the moving template is guided by the column body to form a guide rod, which improves the stability and reduces the cost; the arrangement of multiple column bodies and guide rods forms multiple guiding points, which can improve the linearity of mold movement and reduce interference through mutual restraint; the arrangement of the upright columns can transmit the acting force of the oil cylinder and reduce mold interference; the arrangement of multiple upright columns improves the balance of force transmission and reduces the possibility of local deformation of the mold due to stress; the reinforcing ribs disperse the oil cylinder force to the column bodies, further improving the force balance and reducing mold interference; the reinforcing ribs, upright columns and column bodies form an annular frame, forming an inner accommodation space and protecting the components, reducing the possibility of knocking, bumping and wear during disassembly and assembly. The purpose of the utility model is to provide a template for a large die-casting machine with high stability and low material consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] First, the concepts involved in this application will be described in conjunction with the accompanying drawings. It should be noted here that the following descriptions of each concept are only for making the content of this application easier to understand and do not represent a limitation on the protection scope of this application; at the same time, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. This application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0027] See the attached Figure 1 - attached Figure 3 , a platen of a large die-casting machine, comprising: a moving platen 1 and a rear platen connected in series by guide rods. The moving platen 1 is evenly provided with channels 10 that can pass through the guide rods. The moving platen 1 includes a cylinder 4 configured with the channels 10. The moving platen 1 and the rear platen can adjust the distance relative to the guide rods. Among them, the moving platen 1 is guided by the sliding of the guide rods relative to the channels 10 to increase the stability of the moving platen 1 during the distance adjustment process.

[0028] The cylinder 4 extends along the direction of the guide rods, and the channels 10 are arranged through the cylinder 4. The cylinder 4 along the extension direction of the guide rods forms a fit with the guide rods through the channels 10, increasing the contact surface between the moving platen 1 and the guide rods in the extension direction of the guide rods. Furthermore, the stability of the moving platen 1 in the sliding direction is improved, reducing the possibility of its jitter, which helps to improve the mold clamping stability;

[0029] While the cylinder 4 forms the guiding, it does not increase the overall thickness of the moving platen 1, reducing the weight and consumables. Without affecting the performance, the load on the guide rods is reduced, and the manufacturing cost is lowered.

[0030] The cylinder 4 is provided with oil holes communicating the outside with the channels 10. The oil holes are arranged perpendicular to the channels 10. An annular card slot 11 is coaxially arranged in the channels 10. A ring body can be arranged in the card slot 11. The ring body is arranged in cooperation with the guide rods and the inner wall of the channels 10 to form an oil cavity for lubrication; at the same time, the ring body helps to block the particles attached to the guide rods from entering the through slots, preventing the particles from scratching the inner wall of the channels 10 and causing wear of the moving platen 1.

[0031] The moving platen 1 further includes a column 3. The cylinder 4 and the column 3 are both arranged on the side of the moving platen 1 close to the rear platen. The columns 3 are evenly arranged on the side of the moving platen 1. The cooperative arrangement of the evenly arranged cylinders 4 and the guide rods provides guiding for the moving platen 1 at multiple positions, and can limit each other to ensure the displacement parallelism of the moving platen 1, improving the mold clamping accuracy;

[0032] The multiple cylinders 4 also disperse the load of the moving platen 1 on the guide rods, reducing the force on the guide rods and increasing the service life of the guide rods;

[0033] An oil cylinder is provided on the rear template. The telescopic end of the oil cylinder faces the column 3. The oil cylinder ejects the moving template 1 through telescoping. When the oil cylinder acts, the force at the output end of the oil cylinder acts on the column 3, and then is transmitted to the moving template 1 through the column 3, and finally is transmitted to the mold on the other side of the moving template 1. On the one hand, the setting of the column 3 extends the force transmission path and reduces the interference received by the template. On the other hand, the evenly distributed columns 3 can evenly transmit the acting force of the oil cylinder to the moving template 1, making the force on the template balanced, avoiding the possibility of plastic deformation or even fracture of the template caused by excessive local force, and improving the mold clamping stability.

[0034] The column 3 and the column body 4 are arranged alternately, and a reinforcing rib is fixed between the column body 4 and the adjacent column 3. The reinforcing rib forms the connection between the column 3 and the column body 4, improving the stability of the connection between the column 3 and the column body 4 and the moving template 1. At the same time, when the force of the oil cylinder acts on the column 3, the column 3 can disperse the acting force to each column body 4 through the reinforcing rib. On the one hand, the interference is further reduced through the reinforcing rib, improving the mold clamping stability. On the other hand, the acting range of the acting force is expanded, improving the force balance of the mold, thereby further reducing the possibility of plastic deformation of the mold.

[0035] There is a spacing distance between the reinforcing rib and the side surface of the moving template 1 where the column body 4 is provided. The reinforcing rib is fixed at the position near the end of the moving template 1 and the column 3 to form an outer frame, which is beneficial to protecting the components arranged in the middle of the moving template 1 and reducing the risk of being knocked and damaged during disassembly and assembly.

[0036] An installation cavity 30 recessed inward is provided at the end of the column 3, and a hole body surrounding the outside of the installation cavity 30 is provided at the end of the column 3. The installation cavity 30 can accommodate the telescopic end of the oil cylinder, realizing the guiding of the acting force, ensuring that the acting forces of multiple oil cylinders are perpendicular to the moving template 1, reducing the possibility of tilting and shaking of the moving template 1, improving the mold clamping stability and accuracy, and at the same time reducing the interference between the through groove of the moving template 1 and the guide rod; the setting of the hole body is used for installing the detection component to facilitate the monitoring and control of the die-casting action.

[0037] There is a guiding surface 31 in the installation cavity 30, which is used for moving the connecting plate body. The installation cavity 30 is externally connected with an installation hole group 32, and the installation hole group 32 is used for arranging the power component. The power component is used for the plate body to slide on the guiding surface 31. The power component is connected to the outside of the column 3, and the driving end of the power component can make the plate body slide in the installation cavity 30. The guiding surface 31 restricts the sliding direction of the plate body, so as to lock the telescopic end of the oil cylinder by the plate body on the specified path, so as to fix the moving template 1 and the rear template to realize mold clamping; the uniform arrangement of multiple columns 3 also realizes the uniform distribution of the locking force to ensure the parallelism after the connection between the moving template 1 and the fixed template, which helps to improve the synchronous movement stability of the two.

[0038] The moving platen 1 is provided with a boss 5 at the bottom and extending downward. The boss 5 has an end face perpendicular to the guide rod. The end face is used to connect the mold moving oil cylinder. After the moving platen 1 and the rear platen form a locking connection, the mold moving oil cylinder can cause the moving platen 1 to carry the rear platen and slide axially along the guide rod for mold closing.

[0039] A plurality of columns 3 and a plurality of cylinders 4 are arranged in a ring on one side of the moving platen 1, and the columns 3 and the cylinders 4 are close to the side edges of the moving platen 1. The plurality of columns 3, cylinders 4 and reinforcing ribs form a ring-shaped frame. This ring-shaped frame is close to the edge of the moving platen 1, provides a relatively large installation and layout space for the middle part of the moving platen 1, and forms a protection for the internal components.
