Description

Technical Field

[0001] The invention relates to the technical field of extrusion dies, in particular to an aluminum alloy extrusion die which is convenient for demoulding. Background Art

[0002] Aluminum alloy extrusion dies are designed to improve production efficiency, reduce demoulding difficulty, and ensure product quality. This type of die can effectively solve the problems encountered by traditional dies during demoulding by optimizing design and material selection.

[0003] In order to facilitate the cold shrinkage demoulding of the extruded aluminum alloy profiles, the existing extrusion dies are mostly provided with a refrigerant cooling structure that utilizes the circulation of refrigerant to cool and reduce the temperature. The refrigerant cooling structure includes a refrigerant inlet pipe and an outlet pipe. When the extrusion die is disassembled and assembled, the refrigerant inlet pipe, the refrigerant outlet pipe and the refrigerant circulation pipeline need to be connected and disassembled. However, there is a lack of a synchronous driving mechanism for transmitting a synchronous driving force to implement synchronous tightening and loosening between the positioning installation structure for locking and fixing the extrusion die and the sealing connection structure on the refrigerant inlet pipe and the refrigerant outlet pipe. As a result, when the extrusion die is disassembled and replaced, it is necessary to manually operate the sealing connection structure to loosen and tighten the refrigerant inlet pipe, the refrigerant outlet pipe and the refrigerant circulation pipeline. The operation is relatively troublesome and inconvenient, which reduces the replacement operation efficiency of the extrusion die.

[0004] In addition, although some extrusion dies are equipped with a synchronous drive mechanism to solve the above-mentioned problem, the synchronous drive mechanism and the positioning and mounting structure are mostly directly fixedly connected and cannot be disassembled and separated for power decoupling. As a result, the refrigerant inlet and outlet pipes must and can only be disassembled by the positioning and mounting structure to drive the loosening and tightening. When the refrigerant inlet and outlet pipes are disassembled separately, the extrusion die must be disassembled as a whole, which causes unnecessary trouble. As a result, the extrusion die cannot be used in the working conditions where the refrigerant inlet and outlet pipes are disassembled separately, and its flexibility and practicality are poor. Summary of the invention

[0005] In view of this, the present invention provides an aluminum alloy extrusion die that is easy to demold, so as to solve the problem that when the extrusion die is disassembled, additional manual operation is required to loosen and tighten the refrigerant inlet pipe, the refrigerant outlet pipe and the refrigerant circulation pipeline to disassemble and replace the extrusion die, which is troublesome and inconvenient to operate.

[0006] The technical solution proposed by the present invention is: an aluminum alloy extrusion die for convenient demoulding, specifically comprising: a die mounting carrier, an extrusion die and four positioning screws, wherein the extrusion die is locked and fixed on the die mounting carrier by the four positioning screws; the top and the front side of the lower half of the die mounting carrier are respectively fixed with an L-shaped refrigerant inlet pipe and a refrigerant outlet pipe;

[0007] Two refrigerant pipes are symmetrically welded at the middle positions of the top and bottom parts of the extrusion die, and two sealing sleeves are symmetrically slidably mounted on the two refrigerant pipes. A synchronous driving ring is slidably mounted at the outer edge of the first end of the sealing sleeve through spring pushing; two connecting rods are symmetrically rotatably connected between the synchronous driving ring and the two sealing sleeves, and the synchronous driving ring is used for reciprocating sliding, driving the two sealing sleeves to slide up and down toward each other to respectively connect and seal the two refrigerant pipes with the L-shaped refrigerant inlet pipe and the refrigerant outlet pipe;

[0009] Furthermore,

[0010] The portion of the extrusion die between the two positioning screws on each side is provided with an axial hole;

[0011] Two positioning sliding shafts are symmetrically welded on one side of the synchronous driving ring facing the extrusion die, and the two positioning sliding shafts are correspondingly slidably matched with the two shaft holes through spring pushing.

[0012] Furthermore,

[0013] The head end of the sealing sleeve is an open structure, and the tail end is formed with a first sealing ring;

[0014] A second sealing ring is welded to a portion of the sealing sleeve near the opening, and rubber gaskets are adhesively fixed to the second sealing ring and the first sealing ring on a side away from the extrusion die.

[0015] Furthermore,

[0016] The head ends of the two refrigerant pipes are both formed with thickened sealing rings;

[0017] When the two sealing sleeves slide away from each other, the rubber gaskets on the two first sealing rings are pressed against the two sealing rings for sealing, and at the same time, the rubber gaskets on the two second sealing rings are pressed against the head ends of the L-shaped refrigerant inlet pipe and the refrigerant outlet pipe for sealing.

[0018] Furthermore,

[0019] The tail end of the extrusion die is sealed against the die installation carrier, and a top groove for aluminum alloy raw materials is opened at the tail end of the extrusion die.

[0020] Furthermore,

[0021] Two U-shaped forming grooves are symmetrically opened in the middle position of the interior of the extrusion die, a force-bearing forming block is formed between the two U-shaped forming grooves, a W-shaped refrigerant cavity is opened inside the force-bearing forming block, the W-shaped refrigerant cavity is used to contain and circulate refrigerant, and the two refrigerant ducts are connected to the W-shaped refrigerant cavity.

[0022] Furthermore,

[0023] The head and tail ends of the W-shaped refrigerant cavity are symmetrically blocked with two W-shaped blocking plates, and a W-shaped protrusion is formed on the W-shaped blocking plate on one side facing the W-shaped refrigerant cavity, and the two W-shaped protrusions are plugged into and matched with the openings at the head and tail ends of the W-shaped refrigerant cavity.

[0024] Furthermore,

[0025] A bolt is inserted through the center of the U-shaped blocking plate located at the front end side of the U-shaped refrigerant cavity, and the rear end of the bolt is separately provided with external threads;

[0026] A threaded sleeve is welded on the center of the side of the other Chinese-shaped plugging plate facing the Chinese-shaped refrigerant cavity, the external thread section of the bolt is screwed and connected with the threaded sleeve, and the two Chinese-shaped plugging plates are locked and sealed on the openings at both ends of the Chinese-shaped refrigerant cavity by bolts and threaded sleeves;

[0027] The nut at the head end of the bolt is sealed against the W-shaped blocking plate.

[0028] The aluminum alloy extrusion die provided by the present invention is convenient for demoulding and has the following beneficial effects:

[0029] 1. The two crank slider mechanisms composed of two connecting rods, two sealing sleeves and a synchronous drive ring can transmit synchronous driving force between the two sealing sleeves and the four positioning screws, and implement synchronous tightening and disassembly of the extrusion mold and the two refrigerant pipes. It can be used as a synchronous drive mechanism. Compared with the existing technology that lacks a synchronous drive mechanism, this can save the trouble of additional manual effort to tighten and disassemble the two refrigerant pipes and the L-shaped refrigerant inlet pipe and refrigerant outlet pipe when replacing and disassembling the extrusion mold. It is easy to operate and use, which helps to improve the overall replacement operation efficiency of the extrusion mold.

[0030] 2. The two plug shafts on the four positioning screws can be used as power coupling and decoupling mechanisms between the synchronous drive mechanism and the four positioning screws. This makes the present invention different from the prior art in which the synchronous drive mechanism is directly fixedly connected to the four positioning screws, and the synchronous drive mechanism and the four positioning screws cannot be disassembled and separated for power decoupling. This can avoid the situation in which the two refrigerant conduits can only be disassembled by relying on the four positioning screws to promote the loosening and tightening, and when the two refrigerant conduits are disassembled separately, the extrusion mold must be disassembled as a whole, which causes unnecessary trouble. This makes the extrusion mold suitable for the use condition of disassembling the two refrigerant conduits separately, and has better flexibility and practicality.

[0031] 3. When the hexagonal threaded sleeve is driven by the external wrench to rotate and control the synchronous drive ring to slide away from the extrusion die to independently disassemble the two refrigerant pipes, the external wrench can slide on the hexagonal threaded sleeve toward the extrusion die, and push the slip ring toward the resisting ring, and drive the two plug shafts to slide away from each other to loosen the hexagonal threaded sleeve, and rotate the hexagonal threaded sleeve in the forward direction to push and drive the synchronous drive ring to slide toward the extrusion die, so as to remove the two refrigerant pipes and the L-shaped refrigerant inlet pipe and the refrigerant When the outlet pipe is independently connected and assembled, the two plug shafts will move in the same direction with the hexagonal threaded sleeve. During this process, after the two plug shafts are aligned with the two locating holes on the locating screw, the two plug shafts can automatically engage with the two locating holes under the reverse thrust of the spring on the hexagonal threaded sleeve. In this way, the trouble of manually pulling out the two plug shafts to tighten the hexagonal threaded sleeve when the two refrigerant pipes are independently disassembled and assembled can be eliminated, which is beneficial to improving the operational efficiency of independent disassembly and assembly of the two refrigerant pipes.

[0053] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0054] Please refer to Figures 1 to 10 ;

[0055] Embodiment 1:

[0056] The present invention provides an aluminum alloy extrusion die for convenient demoulding, comprising: a die mounting carrier 1, an extrusion die 2 and four positioning screws 7, wherein the extrusion die 2 is locked and fixed on the die mounting carrier 1 by the four positioning screws 7; an L-shaped refrigerant inlet pipe 3 and a refrigerant outlet pipe 4 are respectively fixed on the top and the front side of the lower half of the die mounting carrier 1;

[0057] Two refrigerant pipes 204 are symmetrically welded at the middle positions of the top and bottom parts of the extrusion die 2, and two sealing sleeves 5 are symmetrically slidably mounted on the two refrigerant pipes 204. A synchronous drive ring 6 is slidably mounted at the outer edge of the head end of the sealing sleeve 5 through spring pushing; two connecting rods 601 are symmetrically rotatably connected between the synchronous drive ring 6 and the two sealing sleeves 5, and the synchronous drive ring 6 is used for reciprocating sliding to drive the two sealing sleeves 5 to slide up and down toward each other to respectively connect and seal the two refrigerant pipes 204 with the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4;

[0058] The two connecting rods 601, the two sealing sleeves 5 and the synchronous drive ring 6 are connected together to form two crank slider mechanisms. Through these two mechanisms, the synchronous drive ring 6 is slid toward or away from the extrusion die 2, and the two sealing sleeves 5 can be driven to slide toward each other to separate from or abut against the head ends of the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4, respectively, so as to implement loosening and disassembly of the two refrigerant conduits 204 and the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4;

[0059] The four positioning screws 7 are symmetrically arranged and respectively penetrate and plug into the outer edge parts of the two ends in the horizontal direction of the extrusion die 2, and the head and tail ends of the positioning screw 7 are both provided with external threads; the rod section close to the head end thread of the positioning screw 7 is welded with a limited stop ring 704, and the head end thread section of the positioning screw 7 is screwed with a hexagonal thread sleeve 701, and the tail end of the hexagonal thread sleeve 701 is formed with a stop ring 702; the half section of the hexagonal thread sleeve 701 close to the stop ring 702 is slidably sleeved with a slip ring 703 through a spring push, and the stop ring 702 Two symmetrically arranged plug shafts 705 are slidably inserted through the circumferential side wall, and two pull rods 706 are symmetrically connected to the two plug shafts 705 and the slip ring 703 for rotation; under normal use, the head end parts of the two plug shafts 705 are plugged into and matched with the positioning screw 7; the parts of the four positioning screws 7 located between the retaining ring 702 and the limit stop ring 704 are jointly rotated through and matched with the synchronous drive ring 6; two positioning holes are symmetrically opened on the rod section of the positioning screw 7 close to the limit stop ring 704, and the two plug shafts 705 are correspondingly plugged into and matched with the two positioning holes.

[0060] The synchronous drive ring 6 is blocked and limited on the four positioning screws 7 by the stop ring 702 and the limit stop ring 704 on the four positioning screws 7. When the four positioning screws 7 are rotated forward and backward to disassemble and assemble the extrusion die 2, the synchronous drive ring 6 can be driven to slide toward or away from the extrusion die 2, and the connection, sealing and loosening and separation operations of the two refrigerant conduits 204 and the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4 are automatically completed. Then, the two curved parts composed of the two connecting rods 601, the two sealing sleeves 5 and the synchronous drive ring 6 are connected together. The handle slider mechanism can transmit synchronous driving force between the two sealing sleeves 5 and the four positioning screws 7, and implement synchronous tightening and disassembly of the extrusion mold 2 and the two refrigerant pipes 204, and can be used as a synchronous driving mechanism. Compared with the existing technology that lacks a synchronous driving mechanism, it can save the trouble of additional manual effort to tighten and disassemble the two refrigerant pipes 204 and the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4 when replacing and disassembling the extrusion mold 2. The operation is convenient and easy to use, which helps to improve the overall replacement operation efficiency of the extrusion mold 2;

[0061] The blocking ring 702 and the limit blocking ring 704 on the four positioning screws 7 can drive and connect the synchronous drive ring 6 with the four positioning screws 7 together through their blocking and limiting effects; the blocking ring 702 and the hexagonal threaded sleeve 701 are inserted and positioned on the positioning screw 7 through two plug shafts 705. The two plug shafts 705 are pulled out of the positioning screw 7 to loosen the hexagonal threaded sleeve 701 and disconnect the transmission connection between the synchronous drive ring 6 and the positioning screw 7, so that the synchronous drive ring 6 can be separated from the four positioning screws 7 and slide back and forth independently, and the two refrigerant conduits 204 and the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4 can be loosened and disassembled separately, so that the two plug shafts 705 on the four positioning screws 7 can be loosened and disassembled. 5 can be used as a power coupling and decoupling mechanism between the synchronous drive mechanism and the four positioning screws 7. Compared with the prior art in which the synchronous drive mechanism and the four positioning screws 7 are directly fixedly connected and the synchronous drive mechanism and the four positioning screws 7 cannot be disassembled and separated for power decoupling, the present invention can avoid the two refrigerant pipes 204 having to rely on the four positioning screws 7 to push the loose and tight disassembly, and when the two refrigerant pipes 204 are disassembled separately, the extrusion die 2 must be disassembled as a whole, which causes unnecessary trouble. The extrusion die 2 can be used in the working condition of disassembling the two refrigerant pipes 204 separately, and the flexibility and practicality of use are better.

[0062] The two inserted shafts 705, the two pull rods 706 and the slip ring 703 are connected together to form two crank slider mechanisms. Through the two mechanisms, the slip ring 703 can be slid toward or away from the retaining ring 702, so that the two inserted shafts 705 can be driven to slide toward each other, and the retaining ring 702 and the hexagonal threaded sleeve 701 can be pulled in and out to tighten or loosen.

[0063] Preferably,

[0064] The portion between the two positioning screws 7 on each side of the extrusion die 2 is provided with an axial hole 202; two positioning sliding shafts 602 are symmetrically welded on the synchronous drive ring 6 on one side facing the extrusion die 2, and the two positions are pushed by springs to slide with the two axial holes 202;

[0065] When the four-sided hexagonal thread sleeve 701 is loosened from the four-sided positioning screw 7, the four-sided hexagonal thread sleeve 701 can freely rotate forward and reverse relative to the four-sided positioning screw 7. When the four-sided hexagonal thread sleeve 701 is loosened, its forward and reverse rotation propulsion effect is used together with the rebound push effect of the internal spring of the two shaft holes 202, which can propel the synchronous drive ring 6 to slide back and forth independently of the four-sided positioning screw 7, so as to realize the separate tightening and disassembly of the two refrigerant pipes 204;

[0066] When the hexagonal threaded sleeve 701 is screwed and driven in the above process, the external wrench needs to be inserted into the half-sleeve near the head end of the hexagonal threaded sleeve 701 and twisted to implement the force; when the hexagonal threaded sleeve 701 is driven by the external wrench to rotate and control the synchronous drive ring 6 to slide away from the extrusion die 2 to independently disassemble the two refrigerant pipes 204, the external wrench can slide on the hexagonal threaded sleeve 701 toward the extrusion die 2, and push the slip ring 703 toward the resisting ring 702, and drive the two plug shafts 705 to slide away from each other to loosen the hexagonal threaded sleeve 701, and when the hexagonal threaded sleeve 701 is rotated in the forward direction, the synchronous drive ring 6 is pushed and driven toward When sliding toward the extrusion die 2 and independently connecting and assembling the two refrigerant conduits 204 and the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4, the two plug shafts 705 will move in the same direction with the hexagonal threaded sleeve 701. During this process, after the two plug shafts 705 are aligned with the two positioning holes on the positioning screw 7, under the reverse thrust of the spring on the hexagonal threaded sleeve 701, the two plug shafts 705 can automatically engage with the two positioning holes. In this way, the trouble of manually pulling out the two plug shafts 705 to tighten the hexagonal threaded sleeve 701 when independently disassembling and assembling the two refrigerant conduits 204 can be eliminated, which is beneficial to improving the operational efficiency of independently disassembling and assembling the two refrigerant conduits 204.

[0067] Preferably,

[0068] The front end of the sealing sleeve 5 is an open structure, and a first sealing ring 501 is formed at the rear end; a second sealing ring 502 is welded to the inner part of the sealing sleeve 5 near the opening, and rubber gaskets are glued and fixed to the second sealing ring 502 and the first sealing ring 501 on the side away from the extrusion die 2.

[0069] Preferably,

[0070] The leading ends of the two refrigerant conduits 204 are both formed with thickened sealing rings; when the two sealing sleeves 5 slide away from each other, the rubber gaskets on the two first sealing rings 501 respectively press against and seal the two sealing rings, and at the same time, the rubber gaskets on the two second sealing rings 502 respectively press against and seal the leading ends of the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4;

[0071] The rubber gaskets on the two first sealing rings 501 can respectively squeeze and seal the sliding gaps between the two first sealing rings 501 and the two refrigerant conduits 204, and the rubber gaskets on the two second sealing rings 502 can respectively squeeze and seal the docking gaps between the two refrigerant conduits 204 and the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4. Furthermore, the four rubber gaskets on the two first sealing rings 501 and the two second sealing rings 502 can ensure the connection sealing performance between the two refrigerant conduits 204 and the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4.

[0072] On the basis of Embodiment 1, Embodiment 2:

[0073] The tail end of the extrusion die 2 abuts and seals against the die installation carrier 1, and an aluminum alloy raw material top groove 205 is formed at the tail end of the extrusion die 2; two U-shaped forming grooves 201 are symmetrically penetrated through the middle position inside the extrusion die 2, and a stress forming block 206 is formed between the two U-shaped forming grooves 201. A king-shaped refrigerant cavity 2061 is penetrated through the stress forming block 206 for containing and circulating refrigerant, and the two refrigerant conduits 204 are both communicated with the king-shaped refrigerant cavity 2061;

[0074] During use, the aluminum alloy raw material after high-temperature heating is pushed into the aluminum alloy raw material top groove 205 and extruded from the two U-shaped forming grooves 201 to form an aluminum alloy profile with a standard shape by relying on the abutting and blocking effect of the aluminum alloy raw material top groove 205;

[0075] During use, the L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4 are connected to an external refrigerant refrigeration cycle system, and the refrigerant circulates in sequence through the L-shaped refrigerant inlet pipe 3, the upper refrigerant conduit 204, the king-shaped refrigerant cavity 2061, the lower refrigerant conduit 204 and the refrigerant outlet pipe 4 in the extrusion die 2. The circulation of the refrigerant in the extrusion die 2 can reduce the temperature of the extrusion die 2 and the formed aluminum alloy profile, so that the formed aluminum alloy profile contracts due to cooling and separates from the inner wall of the U-shaped forming groove 201, removing the tightening and extrusion resistance formed between the aluminum alloy profile and the inner wall of the U-shaped forming groove 201, and facilitating the demolding of the aluminum alloy profile.

[0076] Preferably,

[0077] The head and tail ends of the Wang-shaped refrigerant cavity 2061 are symmetrically blocked with two Wang-shaped blocking plates 203, and a Wang-shaped protrusion 2032 is formed on the Wang-shaped blocking plate 203 on one side facing the Wang-shaped refrigerant cavity 2061, and the two Wang-shaped protrusions 2032 correspond to the openings at the head and tail ends of the Wang-shaped refrigerant cavity 2061 and are plugged into each other.

[0078] Preferably,

[0080] Preferably,

[0081] The die mounting carrier 1 is a part of the aluminum alloy extrusion equipment and is arranged on the aluminum alloy extrusion equipment.

[0082] The working principle of this embodiment is as follows: when in use, the aluminum alloy raw material after being heated at high temperature is pushed into the aluminum alloy raw material top groove 205, and is extruded from the two U-shaped forming grooves 201 to form an aluminum alloy profile of a standard shape by relying on the abutment and blocking effect of the aluminum alloy raw material top groove 205;

[0083] The L-shaped refrigerant inlet pipe 3 and the refrigerant outlet pipe 4 are connected to an external refrigerant refrigeration circulation system, and the refrigerant circulates in the extrusion mold 2 through the L-shaped refrigerant inlet pipe 3, the upper refrigerant conduit 204, the Wang-shaped refrigerant cavity 2061, the lower refrigerant conduit 204 and the refrigerant outlet pipe 4 in sequence. The circulation of the refrigerant in the extrusion mold 2 can reduce the temperature of the extrusion mold 2 and the aluminum alloy profile after molding, so that the aluminum alloy profile after molding shrinks due to the cold and separates from the inner wall of the U-shaped molding groove 201, thereby removing the tightening and extrusion resistance formed between the aluminum alloy profile and the inner wall of the U-shaped molding groove 201, making it convenient to demold the aluminum alloy profile.
