Description

Technical Field

[0001] The invention relates to a molding device, relates to the technical field of electrical equipment molding, and in particular to a profile extrusion molding device. Background Art

[0002] Extrusion molding can be used to produce aluminum profiles with complex cross-sections. The extruded aluminum profiles have high dimensional accuracy, which can ensure the assembly accuracy of the frame, thereby making the structure of the electrical cabinet more stable. In addition, the aluminum profile frame with complex cross-sections facilitates the installation of fixed brackets and guide rails for electrical components in the electrical cabinet.

[0003] An aluminum profile extrusion forming device with publication number CN118650022B includes a push rod, an extrusion head and a first spring for pushing an aluminum rod to be extruded. The inner side of the extrusion head and the outer side of the push rod are provided with first driving threads that cooperate with each other. The extrusion head can rotate while moving back and forth relative to the push rod. When the push rod retreats, the first spring rebounds and pushes the extrusion head forward to keep contact with the aluminum rod and rotate relatively to it, so as to destroy the bonding state between the extrusion head and the aluminum rod.

[0004] Although the aluminum rod is heated to a thermoplastic state in the above invention patent, the friction between the extrusion head and the aluminum rod is still very large. Under normal circumstances, the inner thread of the extrusion head cannot realize the rotational drive of the extrusion head. In addition, the rotation of the extrusion head can only remove the aluminum nails protruding from the surface but cannot remove the aluminum block, which still has a great impact on the extrusion pressure of the aluminum rod.

[0005] To this end, technicians in this field have proposed a profile extrusion molding equipment, which improves the structure of the extrusion molding equipment in the prior art, removes aluminum blocks adhered to the surface of the extrusion head, and reduces the adverse effects of the adhered aluminum blocks on the extrusion force during continuous operation. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a profile extrusion forming equipment, which can be provided at the feeding end of the barrel with a scraper structure that can be pressed against the end of the screw, so that surface attachments can be scraped off as the screw rotates and advances, and can gradually move outwards as the screw advances without affecting the screw entering the barrel for extrusion. After each time the screw completes extrusion forming of the aluminum rod, the aluminum blocks attached to the surface can be cleaned in time to ensure the balance of the extrusion force of the screw on the aluminum rod.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a profile extrusion molding equipment, including a barrel and a screw that advances and extrude inside the barrel, the screw rotates and advances, and applies pressure to the heated aluminum rod in the barrel for extrusion molding.

[0008] When the existing equipment is in use, the screw extrudes the aluminum rod and forms attached aluminum blocks at the end thereof. These attached aluminum blocks are uneven, which will cause uneven stress inside the profile during the process of the screw extruding the aluminum rod, affecting the structural strength of the aluminum profile. It is necessary to periodically clean or even replace the contact structure. This production method will affect the quality of the produced aluminum profiles and greatly affect the production progress.

[0009] In order to solve the above-mentioned problem of residual aluminum blocks attached to the end of the screw, technical personnel in this field have proposed an automatic cleaning structure, which can avoid the attachments from affecting product quality as much as possible without affecting the normal feeding and production of the equipment, and automatically clean the attachments on the end of the screw periodically during the production process.

[0010] A pressure rod is hingedly arranged on the inner side of the barrel, and the pressure rod is arranged inclined toward the inner side of the barrel along the advancing direction of the screw, so that after the aluminum rod is filled in the barrel, there is pressure on the pressure rod, and the cleaning structure is automatically started by the deflection of the pressure rod.

[0011] A connecting rod is hinged on the side of the pressure rod, and the connecting rod extends out of the barrel at one end away from the pressure rod and is connected to a scraper. The pressure rod is deflected at an angle due to the extrusion of the filler, thereby pulling the connecting rod hinged on its side to change its position, and the scraper installed at the end of the connecting rod enters the working position for cleaning the end of the screw.

[0012] The side of the connecting rod extending out of one end of the barrel is hingedly provided with a mounting rod, and the scraper is hingedly provided at the end of the mounting rod. The change of the position of the connecting rod causes the scraper to move toward the central axis of the barrel into a working position.

[0013] A first spring is arranged between the scraper and the mounting rod. The first spring provides the scraper with a certain amount of pressing force on the end of the screw to ensure that the attachments on the end of the screw can be cleaned. The pressure applied to the screw can be converted into an outward pushing force on the connecting rod as the screw advances, thereby realizing the automatic outward advancement of the scraper.

[0014] Preferably, an installation groove is opened on the inner wall of the barrel corresponding to the pressure rod, and the pressure rod extends into the inner side of the installation groove near one end of the screw and is hingedly installed so that after the filling in the barrel is completed, the pressure rod folds and shrinks into the installation groove to avoid affecting the integrity and sealing of the barrel.

[0015] Preferably, the mounting rod comprises a mounting tube, and the mounting tube is hinged to the connecting rod. The mounting tube hinged to the connecting rod can conveniently follow the movement of the connecting rod to change the extension angle of the mounting tube.

[0016] An advancement rod is inserted into one end of the mounting tube close to the screw, and the scraper is hingedly arranged at the extended end of the advancement rod. As the screw approaches the barrel, the pressure of the screw on the scraper compresses the advancement rod toward the inside of the mounting tube, thereby realizing the advancement of the overall driving structure of the scraper toward the outside and avoiding obstruction to the advancement of the screw.

[0017] Preferably, one end of the advancing rod extending into the inner side of the mounting tube is fixedly connected to a second spring, and the second spring provides a clamping force for the scraper at the end of the advancing rod to the end of the screw rod, and the mounting rod can be contracted by compressing the second spring when the screw rod advances, thereby realizing automatic avoidance of the scraper drive structure.

[0018] One end of the second spring away from the advance rod is fixedly connected to an adjustment slider, and the adjustment slider is slidably arranged on the inner side of the installation tube through a positioning mechanism. By adjusting the installation position of the adjustment slider in the installation tube, the second spring can adjust the pressing force of the advance rod.

[0019] Preferably, a fixed shaft is fixedly connected to the side of the barrel, the connecting rod is slidably connected to the fixed shaft, a fixed rod is fixedly connected to the side of the barrel and located on the radius extension line of the fixed shaft, and the mounting rod is hingedly connected to the fixed rod.

[0020] The mounting rod can realize fixed angle deflection under the two-point positioning action of the fixed shaft and the fixed rod, thereby avoiding the problem of unstable force in single-point positioning and damaging the scraper and mounting rod structure.

[0021] Preferably, a protrusion is symmetrically fixed on the side of the end of the connecting rod, and the connecting rod is rotatably connected to the pressure rod via the protrusion. In addition, a folding groove is also provided on the side of the pressure rod corresponding to the connecting rod to facilitate the hinged drive of the pressure rod and the connecting rod.

[0022] The side of the connecting rod is fixedly connected with a sliding rail corresponding to the fixed shaft, and the fixed shaft is slidably connected to the connecting rod through the sliding rail. When the pressure rod is deflected at an angle, the connecting rod hinged thereto is pulled to advance, and also advances a certain distance. The sliding connection between the connecting rod and the fixed shaft through the sliding rail can simultaneously ensure the driving needs of advancement and angle change.

[0023] Preferably, a clamping slider is slidably arranged on the inner side of the slide rail, and a third spring is clamped on the side of the clamping slider. The clamping slider is clamped and rotatably connected to the fixed shaft through the third spring. The clamping slider pressed against the fixed shaft by the third spring can help the installation rod to automatically reset.

[0024] Preferably, the end of the advance rod is fixedly connected to an arc sleeve, the first spring is installed against the side wall of the scraper through the arc sleeve, and one end of the first spring extending into the inner side of the arc sleeve is fixedly connected to a guide slider, and the guide slider is slidably arranged on the inner side of the arc sleeve as a connecting medium between the two sections of the first springs.

[0025] The arc sleeve of the arc structure is convenient for cooperating with one side of the scraper to adjust the tightening force of the screw end. When the scraper is adjusting the tightening force of the screw end, the balanced change of the tightening force on both sides of the scraper is ensured. In addition, the multiple sections of the first spring are connected through the guide slider. The connection and use of multiple sections of the first spring can ensure the adjustment of the tightening force of the scraper as much as possible, and can also ensure that the scraper always fits with the angle deflection caused by the advancement of the screw.

[0026] Preferably, a screw rod is fixedly connected to the side of the guide slider, a slide groove is penetrated through the side wall of the arc sleeve, the screw rod penetrates the slide groove and is threadedly connected with a fastening nut, and the screw rod connected to the fastening nut can adjust the installation position of the end guide slider, thereby adjusting the balanced tightening force of the two ends of the scraper on the end of the screw rod.

[0027] The present invention discloses a profile extrusion molding device, which has the following beneficial effects: 1. The profile extrusion molding equipment is designed with a screw cleaning structure that can cooperate with the automatic advancement of the filler in the barrel. After the filling is completed in the barrel, the scraper arranged at the feed end of the barrel is automatically triggered to advance toward the axis direction. As the screw rotates and advances, it presses against its end to scrape off the attachments. On the one hand, the automatic cleaning structure following the filler can reduce a large amount of manual cleaning and even the loss of replacing parts, thereby improving production efficiency. On the other hand, the scraper gradually moves outward with the extrusion of the screw, automatically completing the avoidance of the screw, and will not cause any obstruction to production.

[0028] 2. The profile extrusion molding equipment senses the change of filler through the pressure rod hinged obliquely on the inner side of the barrel, and automatically moves the scraper following the movement of the filler to prevent the scraper from extending to the inner side of the barrel and affecting the filler. The deflection of the pressure rod pulls the connecting rod hinged on its side to advance and deflect the angle. The connecting rod and the barrel are tightly installed by a pressing slider pressed by a third spring, which can ensure that the length and angle of the connecting rod change with the deflection of the pressure rod, and the installation rod can be automatically reset after the pressure rod loses the filler extrusion.

[0029] 3. The mounting rod of the profile extrusion forming equipment adopts a telescopic mechanism with a second spring pressed against it. When the scraper is squeezed by the advancement of the screw, the decomposed force is converted into pressure on the second spring, so that the scraper gradually moves to the outside of the barrel with the advancement of the screw, avoiding obstruction to the normal operation of the screw. In addition, the mounting rod is installed with a two-point positioning of a fixed shaft and a fixed rod to ensure that the mounting rod follows the accurate angle adjustment of the connecting rod and ensures stable use when subjected to the pressure of the screw.

[0030] 4. In the profile extrusion forming equipment, the scraper adopts the first spring installed in the arc sleeve to press the two ends tightly, and the multiple sections of the first spring in the arc sleeve are connected and guided by the guide slider, so as to ensure that the first spring has a more balanced elastic force adjustment effect on the two ends of the scraper, and ensures that the two ends of the scraper are pressed tightly against the end of the screw, and can adjust its own deflection angle as the screw advances, so as to convert the force of the screw on the scraper into the pressure of the advancement rod on the second spring.

[0035] The embodiment of the present invention discloses a profile extrusion molding device; According to the attached Figure 1 As shown, it includes a barrel 1 and a screw 2 which advances and extrude inside the barrel 1. The screw 2 rotates and advances to apply pressure to the aluminum rod heated in the barrel 1 to perform extrusion molding.

[0036] When the existing equipment is in use, the screw 2 will form attached aluminum blocks at the end of the aluminum rod when it extrude the aluminum rod. These attached aluminum blocks are uneven, which will cause uneven stress inside the profile during the process of the screw 2 extruding the aluminum rod, affecting the structural strength of the aluminum profile. It is necessary to periodically clean or even replace the contact structure. This production method will affect the quality of the produced aluminum profiles and greatly affect the production progress.

[0037] In order to solve the above-mentioned problem of residual aluminum blocks attached to the end of the screw 2, technical personnel in this field have proposed an automatic cleaning structure, which can avoid the attachments from affecting product quality as much as possible without affecting the normal feeding and production of the equipment, and automatically clean the attachments at the end of the screw 2 periodically during the production process.

[0038] According to the attached Figure 2 As shown, a pressure rod 3 is hingedly provided on the inner side of the barrel 1, and the pressure rod 3 is arranged inclined toward the inner side of the barrel 1 along the advancing direction of the screw 2, so that after the aluminum rod is filled in the barrel 1, there is pressure on the pressure rod 3, and the cleaning structure is automatically started by the deflection of the pressure rod 3.

[0039] A connecting rod 4 is hinged on the side of the pressure rod 3. The connecting rod 4 extends out of the barrel 1 at one end away from the pressure rod 3 and is connected to a scraper 5. The pressure rod 3 is deflected by the extrusion of the filler, thereby pulling the connecting rod 4 hinged on its side to change its position. The scraper 5 installed at the end of the connecting rod 4 enters the working position for cleaning the end of the screw 2.

[0040] The side of the connecting rod 4 extending out of one end of the barrel 1 is hingedly provided with a mounting rod 6, and the scraper 5 is hingedly provided at the end of the mounting rod 6. The change of the position of the connecting rod 4 causes the scraper 5 to move toward the central axis of the barrel 1 into the working position.

[0041] According to the attached Figure 3 As shown, a first spring 7 is provided between the scraper 5 and the mounting rod 6. The first spring 7 provides the scraper 5 with a certain amount of pressing force on the end of the screw 2, thereby ensuring that the attachments on the end of the screw 2 can be cleaned. Moreover, as the screw 2 advances, the pressure applied to it can be converted into an outward pushing force on the connecting rod 4, thereby realizing automatic outward advancement of the scraper 5.

[0042] Preferably, a mounting groove 8 is opened on the inner wall of the barrel 1 corresponding to the pressure rod 3, and the pressure rod 3 extends into the inner side of the mounting groove 8 near one end of the screw 2 and is hingedly installed so that after the filling in the barrel 1 is completed, the pressure rod 3 folds and shrinks into the mounting groove 8 to avoid affecting the integrity and sealing of the barrel 1.

[0043] Preferably, the mounting rod 6 includes a mounting tube 601 , which is hinged to the connecting rod 4 . The mounting tube 601 hinged to the connecting rod 4 can conveniently follow the movement of the connecting rod 4 to change the extension angle of the mounting tube 601 .

[0044] An advancement rod 602 is inserted into one end of the mounting tube 601 close to the screw 2, and the scraper 5 is hingedly arranged at the extended end of the advancement rod 602. As the screw 2 approaches the barrel 1, the pressure of the screw 2 on the scraper 5 compresses the advancement rod 602 toward the inside of the mounting tube 601, thereby realizing the advancement of the overall driving structure of the scraper 5 toward the outside, avoiding obstruction to the advancement of the screw 2.

[0045] According to the attached Figure 4 As shown, one end of the advancing rod 602 extending into the inner side of the mounting tube 601 is fixedly connected to a second spring 9, and the second spring 9 provides a clamping force for the scraper 5 at the end of the advancing rod 602 to the end of the screw 2, and the mounting rod 6 can be contracted by compressing the second spring 9 when the screw 2 advances, thereby realizing automatic avoidance of the scraper 5 driving structure.

[0046] The end of the second spring 9 away from the advance rod 602 is fixedly connected with an adjustment slider 10, and the adjustment slider 10 is slidably set on the inner side of the installation tube 601 through a positioning mechanism. By adjusting the installation position of the adjustment slider 10 in the installation tube 601, the second spring 9 can adjust the tightening force of the advance rod 602.

[0047] According to the attached Figure 5As shown, a fixed shaft 11 is fixedly connected to the side of the barrel 1, the connecting rod 4 is slidably connected to the fixed shaft 11, a fixed rod 12 is fixedly connected to the side of the barrel 1 and located on the radius extension line of the fixed shaft 11, and the mounting rod 6 is hingedly connected to the fixed rod 12.

[0048] The mounting rod 6 can realize fixed angle deflection under the two-point positioning action of the fixed shaft 11 and the fixed rod 12, thereby avoiding the problem of unstable force in single-point positioning and damaging the scraper 5 and the mounting rod 6 structure.

[0049] According to the attached Figure 6 As shown, a protrusion 13 is symmetrically fixed on the side of the end of the connecting rod 4, and the connecting rod 4 is rotatably connected to the pressure rod 3 through the protrusion 13. In addition, a folding groove is also provided on the side of the pressure rod 3 corresponding to the connecting rod 4 to facilitate the hinged drive of the pressure rod 3 and the connecting rod 4.

[0050] The side of the connecting rod 4 is fixedly connected with a slide rail 14 corresponding to the fixed shaft 11. The fixed shaft 11 is slidably connected to the connecting rod 4 through the slide rail 14. When the pressure rod 3 is deflected at an angle, the connecting rod 4 hinged thereto is pulled to advance, and also advances a certain distance. The sliding connection between the connecting rod 4 and the fixed shaft 11 through the slide rail 14 can simultaneously ensure the driving needs of advancement and angle change.

[0051] According to the attached Figure 5 As shown, a clamping slider 15 is slidably arranged on the inner side of the slide rail 14, and a third spring 16 is clamped on the side of the clamping slider 15. The clamping slider 15 is clamped and rotatably connected to the fixed shaft 11 through the third spring 16. The clamping slider 15 pressed against the fixed shaft 11 by the third spring 16 can help the installation rod 6 to automatically reset.

[0052] According to the attached Figure 7 and attached Figure 8 As shown, the end of the advance rod 602 is fixedly connected to the arc sleeve 17, the first spring 7 is installed against the side wall of the scraper 5 through the arc sleeve 17, and one end of the first spring 7 extending into the inner side of the arc sleeve 17 is fixedly connected to the guide slider 18. The guide slider 18 is slidably set on the inner side of the arc sleeve 17 as a connecting medium for the two sections of the first spring 7.

[0053] The arc-shaped sleeve 17 is convenient for cooperating with one side of the scraper 5 to adjust the tightening force on the end of the screw 2. When the scraper 5 adjusts the tightening force on the end of the screw 2, the balanced change of the tightening force on both sides of the scraper 5 is ensured. In addition, the multi-section first spring 7 is connected by guiding the slider 18. The connection and use of the multi-section first spring 7 can ensure the adjustment of the tightening force of the scraper 5 as much as possible, and can also ensure that the scraper 5 always fits with the angle deflection caused by the advancement of the screw 2.

[0054] Preferably, a screw rod 19 is fixedly connected to the side of the guide slider 18, a slide groove 20 is penetrated through the side wall of the arc sleeve 17, the screw rod 19 penetrates the slide groove 20 and is threadedly connected with a fastening nut 21, and the screw rod 19 connected with the fastening nut 21 can adjust the installation position of the end guide slider 18, thereby adjusting the balanced tightening force of the two ends of the scraper 5 on the end of the screw rod 2.

[0055] The profile extrusion forming equipment is designed with a screw 2 cleaning structure that can cooperate with the automatic advancement of the filler in the barrel 1. After the filling is completed in the barrel 1, the scraper 5 arranged at the feed end of the barrel 1 is automatically triggered to advance toward the central axis direction. As the screw 2 rotates and advances, it presses against its end to scrape off the attachments. On the one hand, the cleaning structure that follows the automatic filling can reduce a large amount of manual cleaning and even the loss of replacing parts, thereby improving production efficiency. On the other hand, the scraper 5 gradually moves outward with the extrusion of the screw 2, automatically completes the avoidance of the screw 2, and will not cause any obstruction to production.

[0056] Furthermore, the pressure rod 3 hinged at an angle on the inner side of the barrel 1 senses changes in the filler and automatically moves the scraper 5 following the movement of the filler to prevent the scraper 5 from extending to the inner side of the barrel 1 and affecting the filler. The deflection of the pressure rod 3 pulls the connecting rod 4 hinged on its side to advance and deflect the angle. The connecting rod 4 and the barrel 1 are tightly installed by a locking slider 15 locked by a third spring 16, which can ensure that the connecting rod 4 changes in length and angle following the deflection of the pressure rod 3, and can automatically reset the mounting rod 6 after the pressure rod 3 loses filler extrusion.

[0057] Furthermore, the mounting rod 6 is arranged with a telescopic mechanism which is pressed against by a second spring 9. When the scraper 5 is squeezed by the advancement of the screw 2, the decomposed force is converted into pressure on the second spring 9, thereby achieving the purpose of gradually displacing the scraper 5 to the outside of the barrel 1 with the advancement of the screw 2, avoiding obstruction to the normal operation of the screw 2. In addition, the mounting rod 6 is installed with a two-point positioning of the fixed shaft 11 and the fixed rod 12, ensuring that the mounting rod 6 follows the accurate angle adjustment of the connecting rod 4 and ensuring stable use when subjected to the pressure of the screw 2.

[0058] Furthermore, the scraper 5 is tightened at both ends by the first spring 7 installed by the arc sleeve 17, and the multiple sections of the first spring 7 in the arc sleeve 17 are connected and guided by the guide slider 18, to ensure that the first spring 7 has a relatively balanced elastic force adjustment effect on the two ends of the scraper 5, and to ensure that the two ends of the scraper 5 are tightly fitted to the end of the screw 2, and can adjust its own deflection angle as the screw 2 advances, thereby converting the force of the screw 2 on the scraper 5 into the pressure of the advancement rod 602 on the second spring 9.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
