Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die casting moulds, in particular to a cylindrical die casting mould. Background Art
[0002] A mold is a structure of various molds and parts used in industrial production to obtain the desired products by methods such as injection molding, blow molding, extrusion, die-casting, smelting, and stamping. It is an important part of industrial production. The die-casting mold is a die-casting channel in which a molten metal solution is poured. After that, the hydraulic device pushes the piston to apply pressure to the metal solution, pushing the metal solution in the die-casting channel into the die-casting mold. After the metal solution cools down, the material can be unloaded to complete the processing.
[0003] After the die-casting channel has been used for a long time, wear is likely to occur between the piston and the inner wall of the channel. However, one side of the die-casting channel is the die-casting mold, and the other side is the hydraulic device, which means that when replacing the die-casting channel, either the mold or the hydraulic device needs to be disassembled. In addition, the feed port of the die-casting channel may be connected to the feeding mechanism, which means that the feeding structure may also need to be disassembled during the disassembly process to facilitate the removal of the die-casting channel for replacement. The replacement is very cumbersome and time-consuming. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a cylindrical die-casting mold to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cylindrical die-casting mold, comprising a fixed mold and a die-casting channel, one side of the die-casting channel is connected to a head end cylinder sleeve, and a positioning block is fixed above the outer surface of the head end cylinder sleeve, a positioning groove is opened below the outer surface of the head end cylinder sleeve, one side of the head end cylinder sleeve is connected to a first cylinder sleeve, and one side of the first cylinder sleeve is connected to a second cylinder sleeve, one side of the second cylinder sleeve is connected to a tail end cylinder sleeve, and a limiting plate is fixed on one side of the tail end cylinder sleeve, and a limiting bolt passes through one side of the limiting plate.
[0006] By adopting the above technical solution, multiple cylinders are used to replace the die-casting channel to bear wear. When multiple cylinder sleeves are worn and need to be replaced, the head end cylinder sleeve, the first cylinder sleeve, the second cylinder sleeve and the tail end cylinder sleeve can be pulled out from the die-casting channel. The multiple cylinder sleeves are rotatably connected so that the pulled out cylinder sleeves can be rotated forward or backward to avoid collision with the hydraulic device when the multiple cylinder sleeves are pulled out. There is no need to disassemble the mold, the feeding mechanism and the hydraulic device. The installation operation process is the opposite.
[0007] Furthermore, the head end cylinder sleeve is rotatably connected to the first cylinder sleeve, the first cylinder sleeve is rotatably connected to the second cylinder sleeve, and the second cylinder sleeve is rotatably connected to the tail end cylinder sleeve.
[0008] By adopting the above technical solution, the staff inserts the head end cylinder sleeve into the interior of the die-casting channel, and rotates the subsequent multiple first cylinder sleeves, two second cylinder sleeves and two tail end cylinder sleeves and then inserts them into the interior of the die-casting channel.
[0009] Furthermore, the head end cylinder liner, the first cylinder liner, the second cylinder liner and the tail end cylinder liner are all detachably connected to the die-casting channel by sliding, and the limit plate is detachably connected to the die-casting channel by a limit bolt.
[0010] By adopting the above technical solution, the staff can pull out the head end cylinder liner, the first cylinder liner, the second cylinder liner and the tail end cylinder liner from the die-casting channel. The multiple cylinder liner are rotatably connected, so that the several cylinder liner pulled out by the staff can be rotated forward or backward, changing the moving direction of the multiple cylinder liner after being pulled out, and avoiding collision with the hydraulic device when the multiple cylinder liner is pulled out.
[0011] Furthermore, two of the head end cylinder liner, the second cylinder liner, the tail end cylinder liner and the limit plate are each provided, and the two head end cylinder liner, the second cylinder liner, the tail end cylinder liner and the limit plate are all arranged in diagonal mirror images.
[0012] By adopting the above technical solution, the multiple cylinder bodies are all of a half-split structure, which prevents the multiple cylinder bodies from being sleeved on the outside of the piston rod of the hydraulic device and unable to be directly disassembled.
[0013] Furthermore, the first cylinder liners are provided in plurality and divided into two groups, and the two groups of first cylinder liners are arranged in a mirror-image manner, and the plurality of first cylinder liners are rotatably connected to each other.
[0014] By adopting the above technical solution, the number of first cylinder sleeves is increased, so that the length of the combined cylinder sleeves is increased, so as to adapt to the length of the die-casting channel.
[0015] Furthermore, a movable mold is arranged on the top of the fixed mold, and a die-casting channel is fixed on one side of the fixed mold, and a feed port is opened on one side of the top of the die-casting channel.
[0016] By adopting the above technical scheme, during die casting, the movable mold is driven by a hydraulic device to merge with the fixed mold. At this time, a cylindrical cavity is formed between the movable mold and the fixed mold. Then, the molten metal is input into the feed port through the feeding mechanism. The molten metal flows into the fixed mold, the head end cylinder sleeve, the first cylinder sleeve, the second cylinder sleeve and the tail end cylinder sleeve through the feed port and the through hole on the top of the second cylinder sleeve. Then, the hydraulic device on the side of the fixed mold drives the die-casting piston to move horizontally toward the fixed mold, thereby applying pressure to the molten metal, so that the molten metal inside multiple cylinder sleeves is pressed into the cavity between the fixed mold and the movable mold, and at the same time, multiple cylinders are used to replace the die-casting channel to withstand wear.
[0017] Furthermore, a through hole is opened on one side of the top of the second cylinder sleeve, and the feed port corresponds to the through hole.
[0018] By adopting the above technical solution, the molten metal is input into the feed port through the feeding mechanism, and the molten metal flows into the fixed mold, the head end cylinder sleeve, the first cylinder sleeve, the second cylinder sleeve and the tail end cylinder sleeve through the feed port and the through hole on the top of the second cylinder sleeve.
[0019] Furthermore, a top frame is connected to the lower part of the fixed mold, and mounting bolts penetrate the top of the top frame.
[0020] By adopting the above technical solution, after the metal solution is cooled and formed, the movable mold is separated from the fixed mold by a hydraulic device, and then the top frame is pushed upward by the pressure device under the fixed mold, so that the cylindrical workpiece inside the fixed mold is ejected to facilitate the staff to unload the material.
[0021] In summary, the utility model mainly has the following beneficial effects:
[0022] 1. The utility model adopts the arrangement of the head end cylinder sleeve, the first cylinder sleeve, the second cylinder sleeve, the tail end cylinder sleeve, the positioning block and the positioning groove, and uses multiple cylinders to replace the die-casting channel to bear wear.

The limit plate 7 is fixed to one side of the tail end cylinder sleeve 12, and the limit bolt 8 is passed through one side of the limit plate 7. The limit plate 7 is connected to the die casting channel 3 through the limit bolt 8. When installing multiple cylinder sleeves, the staff merges the two head end cylinder sleeves 9. At this time, the positioning is performed through the positioning block 13 and the positioning groove 14 to avoid position deviation after the two head end cylinder sleeves 9 are merged. Then the staff inserts the head end cylinder sleeve 9 into the die casting channel 3, and rotates the subsequent multiple first cylinder sleeves 10, the two second cylinder sleeves 11 and the two tail end cylinder sleeves 12 and then inserts them into the die casting channel 3. Then the staff passes the limit bolt 8 through the limit plate 7 and the die casting channel 3 and tightens it, so as to avoid displacement and falling off of multiple cylinder sleeves.
[0033] See also Figure 1 and Figure 2 In the above embodiment, a plurality of first cylinder liners 10 are provided, which are divided into two groups. The two groups of first cylinder liners 10 are arranged in a mirror image manner, and the plurality of first cylinder liners 10 are rotatably connected to each other. Two head end cylinder liners 9, two second cylinder liners 11, two tail end cylinder liners 12 and two limit plates 7 are each provided. The two head end cylinder liners 9, the second cylinder liners 11, the tail end cylinder liners 12 and the limit plates 7 are all arranged in a diagonal mirror image manner, which is convenient for disassembly in half, and the increased number can correspond to the length of the die-casting channel.
[0034] See also Figure 1 and Figure 2In the above embodiment, a movable mold 2 is arranged on the top of the fixed mold 1, and a die-casting channel 3 is fixed on one side of the fixed mold 1. A feed port 4 is opened on one side of the top of the die-casting channel 3. During die-casting, the movable mold 2 is driven by a hydraulic device to merge with the fixed mold 1.

Then, the hydraulic device on the side of the fixed mold 1 drives the die-casting piston to move horizontally toward the fixed mold 1, thereby applying pressure to the molten metal, so that the molten metal inside the multiple cylinder sleeves is pressed into the cavity between the fixed mold 1 and the movable mold 2, and at the same time, the die-casting channel 3 is replaced by multiple cylinders to withstand wear.
[0035] Embodiment 2:
[0036] On the basis of the above-mentioned embodiment 1, in order to facilitate the blanking of cylindrical die castings, the following settings are now adopted.
[0037] See also Figure 2 In the above embodiment, a top frame 5 is connected to the lower part of the fixed mold 1, and a mounting bolt 6 is passed through the top of the top frame 5. The top frame 5 is pushed upward by the pressure device under the fixed mold 1, so that the cylindrical workpiece inside the fixed mold 1 is ejected to facilitate the staff to unload the material.
[0038] The implementation principle of the utility model is as follows: first, the staff installs the fixed mold 1 on the die-casting workbench, and then the staff prepares three hydraulic devices, which are respectively installed on the movable mold 2 above the movable mold 2, installed on the top frame 5 below the fixed mold 1 through the mounting bolts 6, and corresponding to the die-casting channel 3 on the side of the fixed mold 1, and the output end of the hydraulic device on the side of the fixed mold 1 is connected with a die-casting piston extending into the die-casting channel 3; it should be noted that a gap is left between the hydraulic device on the side of the fixed mold 1 and the die-casting channel 3, and the span of the gap is greater than twice or more than twice the length of the tail end cylinder sleeve 12, so as to facilitate the subsequent disassembly and assembly of the head end cylinder sleeve 9, the first cylinder sleeve 10, the second cylinder sleeve 11 and the tail end cylinder sleeve 12; then the staff connects the feeding mechanism to the feed port 4;
[0039] During die casting, the movable die 2 is driven by a hydraulic device to merge with the fixed die 1. At this time, a cylindrical cavity is formed between the movable die 2 and the fixed die 1. Then, the molten metal is input into the feed port 4 through the feeding mechanism. The molten metal flows into the fixed die 1, the head end cylinder liner 9, the first cylinder liner 10, the second cylinder liner 11 and the tail end cylinder liner 12 through the feed port 4 and the through hole on the top of the second cylinder sleeve 11. Then, the hydraulic device on the side of the fixed die 1 drives the die casting piston to move horizontally toward the fixed die 1, thereby applying pressure to the molten metal, so that the molten metal inside the multiple cylinder sleeves is pressed into the cavity between the fixed die 1 and the movable die 2, and at the same time, the die casting channel 3 is replaced by multiple cylinders to withstand wear;
[0040] After the metal solution is cooled and formed, the movable mold 2 is separated from the fixed mold 1 by a hydraulic device, and then the pressure device under the fixed mold 1 pushes the top frame 5 upward to eject the cylindrical workpiece inside the fixed mold 1, so that the staff can unload the material;
[0041] When multiple cylinder sleeves are worn and need to be replaced and disassembled, the staff removes the limit bolt 8 to end the limit of the limit plate 7, and then the staff can pull out the head end cylinder sleeve 9, the first cylinder sleeve 10, the second cylinder sleeve 11 and the tail end cylinder sleeve 12 from the die casting channel 3. The multiple cylinder sleeves are rotatably connected, so that the cylinder sleeves pulled out by the staff can be rotated forward or backward, changing the direction of travel of the multiple cylinder sleeves after being pulled out, avoiding collision with the hydraulic device when the multiple cylinder sleeves are pulled out, and there is no need to disassemble the mold, the feeding mechanism and the hydraulic device;
[0042] When installing multiple cylinder liners, the staff will merge the two head end cylinder liners 9, and at this time, they will be positioned through the positioning block 13 and the positioning groove 14 to avoid position deviation after the two head end cylinder liners 9 are merged. Then the staff will insert the head end cylinder liners 9 into the die-casting channel 3, and rotate the subsequent multiple first cylinder liners 10, two second cylinder liners 11 and two tail end cylinder liners 12 and then insert them into the die-casting channel 3. Then the staff will pass the limit bolt 8 through the limit plate 7 and the die-casting channel 3 and tighten it to avoid displacement and falling off of the multiple cylinder liners.
