Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Through research, the existing extrusion machine forming die mainly adopts a flat cooling tool. The extruded material is cooled and formed through a forming die to form a compact fibrous structure. However, due to the structural limitations, the discharge efficiency of such a forming die is not high, and it is necessary to make it particularly wide if mass production is to be maintained. Meanwhile, in order to maintain the sealing of the molding passage, a plurality of fastening members need to be provided in the lengthwise direction of the molding die. Once the fastener needs to be disassembled for maintenance or cleaned, a lot of fasteners must be disassembled and assembled, which not only wastes time and labor, but also is difficult to realize automatic control. Therefore, how to improve the existing forming die for the extruder to improve the extrusion forming efficiency and the disassembly and assembly convenience becomes a problem to be solved urgently.
In order to solve the problems, the invention provides a forming die for an extruder and a material extrusion forming and dismounting method thereof.
As shown in fig. 1 to 3, the present embodiment provides an extruder forming die, which includes a base 1, a die main body 2, and a moving assembly 3. Wherein the mold body 2 includes a die assembly 21, an outer cylinder 22, and an inner cylinder 23. The moving assembly 3 is used for moving the outer cylinder 22 to move the outer cylinder 22 and the inner cylinder 23 relatively.
Referring to fig. 4 and 8, one end of the die assembly 21 is connected to the discharge end of the extruder, and the other end of the die assembly 21 is connected to the outer cylinder 22 and the inner cylinder 23. Specifically, die assembly 21 includes diverter body 211 and deflector cone 212. Wherein, the two ends of the branch fluid 211 are respectively provided with a circular opening and extend inwards to form a first cavity part 2111 and a second cavity part 2112. A plurality of extrusion flow passages 2113 communicating with the first chamber portion 2111 and the second chamber portion 2112 are formed therebetween. The outer port of the first chamber portion 2111 communicates with the discharge port of the extruder. Deflector cone 212 is a conical structure. The guiding cone 212 is coaxially disposed in the first cavity of the flow splitting body 211, and is fixed to the flow splitting body 211. The tapered surface of the guide cone 212 and the inner wall of the circumferential surface of the first cavity portion 2111 form a tapered flow passage 213. The tapered flow passage 213 communicates with the extrusion flow passage 2113. The material extruded from the extruder is blocked by the guide cone 212, uniformly distributed along the tapered surface of the guide cone 212, and then enters the second cavity portion 2112 from the tapered runner 213 through the extrusion runner 2113.
Referring to fig. 5, the outer cylinder 22 and the inner cylinder 23 are both cylindrical structures, and the outer cylinder 22 and the inner cylinder 23 are coaxially sleeved. The outer cylinder 22 has an inner diameter larger than an outer diameter of the inner cylinder 23 so that an annular forming flow passage 24 is formed therebetween. The material extruded by the extruder is directed through die assembly 21 to a shaping channel 24. Specifically, the outer diameter of inner barrel 23 is less than the inner diameter of second chamber portion 2112. An annular protrusion 2114 is provided at the inner end of the second chamber portion 2112, and the inner cylinder 23 extends into the second chamber portion 2112 and abuts against the annular protrusion 2114. The inner diameter of the outer cylinder 22 and the inner diameter of the second cavity are equal or approximately equal. The outer cylinder 22 abuts an end of the shunt fluid 211 remote from the first cavity portion 2111. Thereby placing the outer port of the second cavity 2112 in communication with the molding runner 24. Therefore, the material entering the second cavity 2112 is uniformly guided to the forming runner 24, and a uniform annular structure is formed in the forming runner 24, and a stable texture is formed. Compared with a flat forming die, the annular forming runner 24 can increase the discharging area of the forming runner 24 in a limited space, so that the forming discharging efficiency is improved, and the forming die is suitable for mass production.
In order to facilitate the material forming process, a first cooling channel 221 for flowing a cooling medium is formed inside the outer cylinder 22. Meanwhile, a second cooling flow channel 231 for flowing a cooling medium is formed inside the inner cylinder 23. The first cooling flow passage 221 and the second cooling flow passage 231 operate independently. Through continuously supplying the cooling medium in first cooling runner 221 and second cooling runner 231, cool down the material in shaping runner 24 through the heat exchange, promote the material cooling shaping of high temperature to form stable texture. The temperature of the cooling medium after heat exchange is increased, and the part of the cooling medium can be discharged. The cooling medium can be liquid or gas. Preferably, the temperature reducing medium may be water.
In the prior art, a cooling runner of a flat forming die mostly adopts a linear space along the length direction of the forming die or an annular space along the circumferential direction of the forming die, and then is communicated with a water inlet pipe and a water outlet pipe. Although the cooling runner with the structure can play a certain cooling role. But the cross section of the space formed by the cooling flow channel is usually larger than that of the water inlet pipe and the water outlet pipe. Therefore, the water entering from the water inlet pipe forms a vortex in the cooling flow channel, and the first-in first-out cannot be ensured. That is, the temperature of the water entering first is raised in the heat exchange process, and the water should be discharged first, so that the temperature reduction effect can be ensured. Referring to fig. 6 and 7, in this embodiment, the first temperature-reducing flow passage 221 is a spiral first conduit 2211, and a feed inlet and a discharge outlet of the first conduit 2211 are both located at an end of the outer cylinder far from the die assembly 21. Specifically, the first conduit 2211 is spirally wound in a bifilar manner. The second cooling runner 231 adopts a spiral second pipeline 2311, and a feeding hole and a discharging hole of the second pipeline 2311 are both positioned at one end of the inner cylinder far away from the die head assembly 21. Also, the second pipe 2311 is also helically wound in a bifilar manner. On the one hand, the spiral structure can enable the cooling medium to be in first-out, and the cooling effect is ensured. On the other hand, the first cooling runner 221 and the second cooling runner 231 cool the annular material from both sides, so that the cooling effect is further improved. The spiral directions of the first cooling channel 221 and the second cooling channel 231 in this embodiment may be the same or opposite. Preferably, the first temperature-reducing flow passage 221 and the second temperature-reducing flow passage 231 have opposite spiral directions. When the spiral direction is the same, the molding material can produce temperature difference along circumference, leads to the cooling rate of material to produce the difference, influences the texture of material. When the spiral directions are opposite, the first cooling runner 221 and the second cooling runner 231 can complement each other, so that the temperature difference of the molding material in the circumferential direction is reduced as much as possible, the difference of the cooling rate is reduced, and the structure of the material is kept stable.
It has been mentioned above that the outer cylinder 22 is movable relative to the inner cylinder 23, and in particular the outer cylinder 22 is movable along the length of the inner cylinder 23. In this embodiment, the outer cylinder 22 and the fluid distribution member 211 are detachably connected to each other. The end of the diverter body 211 adjacent the outer cylinder 22 is provided with an annular first step 2115. Meanwhile, the end of the outer cylinder 22 close to the flow dividing body 211 is provided with an annular second step 222. When the diverter body 211 is docked with the outer cylinder 22, the hoop 25 is circumferentially disposed along the first step 2115 and the second step 222 to connect the diverter body 211 with the outer cylinder 22. Through the cooperation of the hoop 25 and the first step 2115 and the second step 222, the tight butt joint of the flow dividing body 211 and the outer cylinder 22 is ensured, so that the overflow of materials is avoided. Meanwhile, in order to prevent the outer cylinder body 22 and the flow dividing body 211 from generating circumferential rotation errors, the end faces of the butt joint of the flow dividing body 211 and the outer cylinder body 22 are respectively provided with positioning holes 223 which are equal in number and correspond to each other one by one. By providing the positioning pin 26 in the positioning hole 223, the positioning hole 223 and the positioning pin 26 are matched to allow precise docking of the divided fluid 211 and the outer cylinder 22.
Referring to fig. 8, the driving assembly in the present embodiment includes a support member 31 and a driving member 32. The supporting member 31 is fixedly connected to the outer cylinder 22 and is used for supporting the outer cylinder 22. The support member 31 is provided on the base 1 and is movable along the base 1. The driving member 32 includes a hydraulic cylinder 321 provided on the base 1, and a movable end of the hydraulic cylinder 321 is connected to the supporting member 31. The support member 31 can be driven to move along the base 1 by the hydraulic cylinder 321, and the outer cylinder 22 can be moved. Specifically, the base 1 is provided with a rail 11. The support member 31 may be engaged with the rail 11 in a sliding manner. Of course, the bottom of the supporting member 31 may also be provided with a roller mechanism adapted to the rail 11, so as to realize the rolling fit between the supporting member 31 and the base 1. After the hoop 25 is disassembled, the hydraulic cylinder 321 of the driving part 32 drives the outer cylinder 22 to move through driving the supporting part 31, so that the outer cylinder 22 and the inner cylinder 23 are gradually separated and finally separated, and the outer wall of the inner cylinder of the forming mold and the inner wall of the outer cylinder 22 are conveniently cleaned. Compare in prior art set up a plurality of fastener structures in the length direction along forming die, the loaded down with trivial details degree that technical scheme that this embodiment provided can greatly reduced manual operation, labour saving and time saving. Meanwhile, the automatic separation of the outer cylinder body 22 and the inner cylinder body 23 can be realized through the automatic control of the hydraulic cylinder 321, so that the automatic upgrade and modification of equipment are facilitated. For the hydraulic cylinder 321 to work normally, a hydraulic station 322 connected to the hydraulic cylinder 321 should also be provided. Of course, the pushing to the outer cylinder 22 should not be limited to the hydraulic pushing scheme, and other schemes such as servo electric cylinder, rack and pinion transmission, lead screw traction, etc. may also be adopted.
When the outer cylinder 22 is separated from the inner cylinder 23, the inner cylinder 23 becomes a cantilever structure, and its main support is converted into a force to the split fluid 211. In order to solve this problem, in the present embodiment, the forming die for an extruder further includes a jacking mechanism 4. The jack 4 includes a free end that can move up and down. When the outer cylinder 22 moves along the inner cylinder 23 to the end of the inner cylinder 23 far away from the die assembly 21, the free end of the jacking mechanism 4 moves upwards and contacts with the outer wall of the inner cylinder 23 to support the inner cylinder 23. The jacking mechanism 4 in this embodiment may employ a hydraulic cylinder.
When the outer cylinder 22 is fixedly connected with the flow dividing body 211, a molding flow passage 24 is formed between the outer cylinder 22 and the inner cylinder, and the inner cylinder 23 is actually in a cantilever state. Therefore, in the present embodiment, the inner wall of the bottom of the outer cylinder 22 is provided with the support rib 224 along the length direction of the outer cylinder 22. The top of the support rib 224 is abutted against the outer wall of the bottom of the inner cylinder 23, the inner cylinder 23 is supported by the support rib 224, the support force is distributed to the outer cylinder 22, and then the support force is transferred to the base 1 through the support part 31. Meanwhile, the supporting ribs 224 can cut the annular material in the molding runner 24 from the bottom, so that the annular material is notched at the bottom. In addition, the top of the outer cylinder 22 far away from the end of the die assembly 21 is provided with a cutter 225. The material extruded from the forming passage is cut by the cutter from the top along the axial direction of the outer cylinder. The material finally extruded from the molding runner 24 is cut into two parts by the support ribs 224 and the cutter 225, thereby facilitating drainage and flattening delivery.
In a further embodiment, referring to fig. 9, the forming die for the extruder further includes a conveying device 5 for receiving the forming material extruded from the forming runner 24 and performing preliminary flattening. The conveying device 5 is arranged on the side of the base 1 far away from the die head assembly 21. The conveying device 5 can prevent the formed materials from being stacked and bonded. Specifically, the conveying device 5 includes a conveying support 51 disposed on the base 1, and a conveying belt 52 disposed on the conveying support 51. The number of the conveyor belts 52 is two. The conveying surfaces of the two conveying belts 52 are V-shaped in cross section in a direction perpendicular to the length direction of the forming runner 24. When the annular material is extruded from the forming runner 24, the annular material is divided into a left semicircular structure and a right semicircular structure, the two semicircular structures have a certain overlapping area in the vertical direction, the conveying surface of each conveying belt 52 is an inclined surface due to the design of the conveying belts 52 with the V-shaped structures, flattening spaces are formed in the vertical direction and the horizontal direction, and the parts, close to the lower ends, of the semicircular material are firstly contacted with the lower end parts of the inclined surfaces and gradually flattened along the inclined surfaces in the falling process. Preferably, the average height of the conveyor belt 52 at the end near the molding runner 24 is higher than the average height of the conveyor belt 52 at the end far from the molding runner 24. And the angle of the V-shaped included angle of the two conveying belts 52 close to one end of the forming runner 24 is smaller than that of the V-shaped included angle far away from one end of the forming runner 24. The advantage of this arrangement is that the two conveyor belts 52 can better receive the cut material. Moreover, the angle of the V-shaped included angle gradually increases, so that the received materials are gradually flattened, and the materials are prevented from being stacked due to the angle of the V-shaped included angle.
The working principle is as follows: when the material extruded by the extruder needs to be cooled and formed, the material extruded from the discharge end of the extruder is firstly homogenized through the die head assembly 21 and guided to the annular forming runner 24. The material is bonded within the molding runner 24 to form an annular structure that is notched at the bottom. The first cooling channel 221 and the second cooling channel 231 are continuously supplied with cooling medium, and the annular material in the molding channel 24 is cooled through heat exchange, so that the material in the molding channel 24 is cooled and molded, and a stable structure is formed. The annular material is extruded from the molding runner 24, the cutter 225 arranged at the end part of the outer cylinder body 22 cuts the annular material from the upper part of the annular material along the axial direction of the outer cylinder body, so that the annular material is separated into two parts and respectively falls on the conveying device 5, and the conveying device 5 conducts drainage on the separated material and gradually flattens the material.
When the forming die for the extruder needs to be maintained and cleaned, the hoop 25 is firstly disassembled. Then, the hydraulic cylinder 321 is started, so that the movable end thereof pushes the supporting member 31 to drive the outer cylinder 22 to separate from the diverting body 211, and the outer cylinder 22 moves along the length direction of the inner cylinder 23 and gradually separates from the inner cylinder 23. When the outer cylinder 22 moves along the inner cylinder 23 to the end of the inner cylinder 23 away from the die assembly 21, the inner cylinder 23 is supported by the jacking mechanism 4. When the outer cylinder 22 and the inner cylinder 23 are completely separated, the inner wall of the outer cylinder 22 and the outer wall of the inner cylinder 23 can be cleaned and maintained. After the cleaning is completed, the hydraulic cylinder 321 is started again, so that the outer cylinder 22 and the inner cylinder 23 gradually approach each other, and the outer cylinder 22 is abutted to the diverting body 211. In this process, the support of the inner cylinder 23 by the jack 4 is removed. Finally, the anchor ear 25 is installed.
