Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of die-casting machines, and in particular relates to a detachable barrel and a die-casting machine. Background Art
[0002] The traditional die-casting machine's integral trough is one-piece, and the inner and outer diameters of the trough are processed as a whole. During the production process, the high-temperature molten metal is poured into the trough from the inlet of the integral trough, and then the die-casting machine punch quickly pushes the molten metal into the mold to fill the cavity. After the filling is completed, the punch returns to its original position, thus completing a die-casting process. In this process, the concentricity requirements of the punch and the trough are extremely high, and the deviation is generally required to be no more than 0.05mm. After a period of production, with the continuous friction between the punch and the trough, and the continuous flushing of the trough when the molten metal is poured in, the diameter of the trough at the port will gradually increase, and even exceed the tolerance requirements. At this time, the trough size may be out of tolerance, and even the punch may be stuck, which is extremely unfavorable for production.
[0003] When the inner diameter of the integral material tank is out of tolerance and cannot be reproduced, there are two common solutions: one is to repair the inner diameter by welding, and then process the inner diameter repair welding position to make the size meet the tolerance requirements, but the use effect after repair welding and reprocessing is usually not ideal, and the tolerance problem will appear again after a few uses. Repair welding will not be chosen unless it is urgent; the second is to replace a new integral material tank, but the size of the integral material tank is large and the manufacturing cost is high, which increases the cost of die-casting production. Summary of the invention
[0004] In response to one or more of the above defects or improvement needs of the prior art, the present invention provides a detachable barrel and a die-casting machine, wherein the vulnerable parts of the barrel can be detached from the main body for quick replacement, thereby ensuring the production quality of the die-casting machine and reducing the die-casting production cost.

[0009] As a further improvement of the present invention, there are a plurality of first limiting members, each of which is arranged at an interval at the end of the feeding section, and the limiting blind holes are arranged in a one-to-one correspondence with the first limiting members.
[0010] As a further improvement of the present invention, the limiting assembly includes a second limiting member, which is respectively abutted against the end face of the feeding section and the end face of the inlay, and the side of the second limiting member facing the axis of the cylinder is located between the inner wall of the feeding section and the inner wall of the inlay.
[0011] As a further improvement of the present invention, there are a plurality of second position-limiting members, and each of the second position-limiting members is arranged at intervals at the end of the feeding section.

[0029] Example: See also Figure 1~Figure 4 The detachable barrel in the preferred embodiment of the present invention includes a barrel body 1 and an inlay 2, wherein the barrel body 1 includes an inlet section 11 and an outlet section 12 continuously arranged along the axis, wherein the port of the inlet section 11 is the entrance for the die-casting punch to enter the barrel. During the production process, the die-casting punch continuously impacts the port when entering the barrel, causing the port to be easily worn by the impact and resulting in dimensional deviation, thereby making the barrel unable to continue to be used. The inlay 2 in this embodiment is arranged in the inlet section 11, covering the entrance position of the die-casting punch. If the size of this part is out of tolerance and unqualified, the inlay 2 can be removed and replaced, which can reduce the cost of replacing the entire barrel.
[0030] Specifically, Figure 3 , 4 As shown, the feed section 11 and the discharge section 12 are respectively provided with a first channel 111 and a second channel 121 along the axis of the cylinder 1, the first channel 111 and the second channel 121 form a stepped channel, the inner wall of the feed section 11 is provided with a mounting position 112, and the side wall of the feed section 11 is provided with a feed port 113; the inlay 2 is provided with a third channel 21, the cross section of the third channel 21 is consistent with the cross section shape and size of the second channel 121, the side wall of the inlay 2 is provided with an opening 22, and the shape and size of the inlay 2 match the mounting position 112. In this embodiment, the cross-section of the third channel 21 and the second channel 121 refers to the projection of the third channel 21 and the second channel 121 perpendicular to the axis direction of the cylinder 1. The cross-section of the third channel 21 and the second channel 121 can be circular, square, polygonal, etc., and the specific shape is not limited.
[0031] Furthermore, the inlay 2 is detachably arranged in the installation position 112 , so that the third channel 21 abuts against the end of the second channel 121 to form a die-casting stroke channel with a continuous inner wall surface, and the opening 22 of the inlay 2 is aligned with the feed port 113 .
[0032] In this embodiment, the wall thickness of the inlay 2 is the step difference formed by the first channel 111 and the second channel 121. After the inlay 2 is installed in the installation position 112 of the feed section 11, the space formed by the step difference between the first channel 111 and the second channel 121 is filled, and the third channel 21 in the inlay 2 and the first channel 111 form a continuous die-casting stroke channel, so that the die-casting punch can move along the die-casting stroke channel. At the same time, the opening 22 of the inlay 2 is also aligned with the feed port 113, so that the raw material can enter the die-casting stroke channel from the feed port 113 and be pushed by the die-casting punch. As the raw materials are poured into the barrel from the feed port 113, the part of the barrel opposite to the feed port 113 will be continuously flushed, so that the channel size of the barrel at this part gradually increases, exceeding the tolerance requirement, resulting in the phenomenon that the die-casting punch is easily worn or even stuck at this part. In the present invention, the feed section 11 includes the part opposite to the feed port 113 and the entrance of the die-casting punch into the barrel, which are two places prone to wear. Therefore, the inlay 2 is detachably set at the installation position 112 of the feed section 11, so that the dimensional tolerance problem of the barrel at these two places can be solved by replacing the inlay 2. In addition, the inlay 2 is small in size, and the replacement is relatively simple and the replacement cost is low, which can reduce the die-casting production cost.
[0033] Preferably, the opening 22 and the feed opening 113 are consistent in shape and size.
[0034] Preferably, the outer periphery of the inlay 2 and the mounting position 112 are interference fit.

[0037] In this embodiment, the first limit member 31 cooperates with the limit blind. On the one hand, the end surface of the first limit member 31 facing the first channel 111 respectively abuts against the side wall surface of the first limit groove 23 and the side wall surface of the second limit groove 114, which can limit the axial displacement of the inlay 2 along the cylinder body 1; on the other hand, the side wall surface of the first limit member 31 along the circumferential direction of the cylinder body 1 also abuts against the side wall surface of the first limit groove 23 and the side wall surface of the second limit groove 114, which can limit the rotation of the inlay 2 along the circumferential direction of the cylinder body 1, so that the inlay 2 and the cylinder body 1 are tightly matched and will not loosen, thereby meeting the assembly requirements of the inlay 2.
[0038] Preferably, there are a plurality of first limiting members 31 , each of which is arranged at intervals at the end of the feeding section 11 , and the limiting blind holes are arranged one-to-one with the first limiting members 31 to strengthen the tight connection between the inlay 2 and the cylinder 1 .
[0039] Preferably, the first limiting member 31 is fixedly connected to the feeding section 11 by a fastener, and the first limiting member 31 is fixed in the limiting blind hole.
[0040] In a preferred embodiment, the limiting component 3 includes a second limiting member 32, which is respectively abutted against the end face of the feed section 11 and the end face of the inlay 2, and the second limiting member 32 is located between the inner wall of the feed section 11 and the inner wall of the inlay 2 on the side facing the axis of the cylinder 1, that is, the second limiting member 32 can limit the axial movement of the side wall of the inlay 2 along the cylinder 1, and at the same time, the structure of the second limiting member 32 will not invade the extension space where the die-casting stroke channel is located, so as not to affect the movement of the die-casting punch.
[0041] Preferably, there are a plurality of second limiting members 32 , and each of the second limiting members 32 is disposed at intervals at the end of the feeding section 11 to strengthen the tight connection between the inlay 2 and the cylinder 1 .
[0042] Preferably, the second limiting member 32 is a sector-shaped ring, and when the sector-shaped ring is fixedly connected to the second channel 121 , the center of the sector-shaped ring is located on the axis of the cylinder 1 .
[0043] Preferably, the inlay 2 is a cylindrical structure, and the cross-sections of the first channel 111, the second channel 121, and the third channel 21 are all circular, wherein the diameters of the first channel 111 and the third channel 21 are equal, and the diameter of the second channel 121 is equal to the outer diameter of the inlay 2. At this time, the cylinder 1 and the inlay 2 are regular in shape and easy to process.
[0044] In a specific embodiment, Figure 1 and Figure 2As shown, the inlay 2 is a cylindrical structure, the cross-sections of the first channel 111, the second channel 121, and the third channel 21 are all circular, the opening 22 is the same in shape and size as the feed port 113, and the end faces of the inlay 2 and the feed section 11 are provided with a first limiter 31 to limit the rotation and axial movement of the inlay 2, and a second limiter 32 to limit the axial movement of the inlay 2. The installation process of the detachable barrel of the present invention is: insert the inlay 2 into the second channel 121 from the side of the feed section 11 and put it into the installation position 112, so that the second channel 121 is aligned with the third channel 21, the opening 22 is aligned with the feed port 113, the first limiter groove 23 and the second limiter groove 114 are aligned, the first limiter 31 is installed in the limiter blind hole and fixed by a fastener, and finally the second limiter 32 is fixed to the end face of the feed section 11 by a fastener. The disassembly process of the detachable barrel of the present invention is to reverse the installation process to remove the inlay 2 from the barrel 1.
[0045] Furthermore, the present invention also provides a die-casting machine, in which the above-mentioned detachable barrel is provided.
[0046] The detachable barrel of the present invention comprises a barrel 1 and an inlay 2, wherein the first channel 111 and the second channel 121 of the feed section 11 and the discharge section 12 of the barrel 1 are set as stepped channels, a feed port 113 and a mounting position 112 are set on the feed section 11, the inlay 2 is set as a structure matching the shape and size of the mounting position 112, and a third channel 21 having the same cross section as the second channel 121 and an opening 22 is opened on the side wall, and the inlay 2 is detachably connected to the mounting position 112 so that the ends of the second channel 121 and the third channel 21 are aligned and abutted to form a continuous die-casting stroke channel, and the feed port 113 is also aligned with the opening 22 so that the raw material enters the die-casting stroke channel. The present invention sets the part of the barrel that is prone to wear (i.e., the feed port and the port near the feed port) as a detachable inlay, so that the part can be easily replaced when the wear size exceeds the tolerance, which can not only ensure the quality of the die-casting production product, but also reduce the die-casting production cost.
[0047] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
