Description

Technical Field

[0001] This invention relates to the field of traffic cone production equipment, and in particular to an automatic injection molding equipment for traffic cones. Background Technology

[0002] A type of plastic traffic cone, such as Figure 13 As shown, the cone includes a cone body 91 and a base 92. During production, the mold is first installed on an injection molding machine 1. The injection molding machine 1 then controls the mold opening and closing, as well as the injection of plastic, to automate the injection molding production of the traffic cone. However, after each injection molding process, a glue outlet is formed in the injection channel 422 of the mold. This glue outlet is connected to the base 92. When the traffic cone is demolded, the glue outlet also demolds along with the traffic cone. Due to the presence of the glue outlet, personnel are required to trim it off the traffic cone after production. Therefore, the presence of the glue outlet increases labor costs and reduces overall production efficiency in traffic cone production. Summary of the Invention

[0003] This application provides an automatic injection molding equipment for traffic cones, which has the function of automatic injection molding of traffic cones.

[0004] The automatic injection molding equipment for traffic cones provided in this application adopts the following technical solution:

[0005] An automatic injection molding equipment for traffic cones includes an injection molding machine and a traffic cone forming mold mounted on the injection molding machine. The traffic cone forming mold includes an upper mold body and a lower mold body. The upper mold body includes an upper fixed plate and a fixed template. The lower mold body includes a lower fixed plate and a movable template. The fixed template has two through holes. Two injection channels for hot-melt plastic flow are provided on the side of the fixed template facing the movable template, with one end of the two injection channels connected. The upper fixed plate has two conical inserts for forming the traffic cone. The two conical inserts pass through the two through holes and extend out of the fixed template. The movable template has two receiving holes for cooperating with the conical inserts to produce the traffic cone. A sliding groove, U-shaped, is provided on the side of the fixed template facing the movable template. The two injection channels are spaced apart. One end of each is connected to a sliding groove. Both through holes are opened on the bottom wall of the sliding groove. Several first mounting holes are opened on the bottom wall of the sliding groove. Guide posts are provided in the several first mounting holes. A U-shaped top plate for forming the base is also provided in the sliding groove. The top plate is slidably connected to several guide posts along the mold opening direction. The fixed template is also provided with a first driving part for driving the top plate to move toward the moving template. Two cutting blocks are provided on the side of the fixed template facing the moving template. The two cutting blocks are respectively located above the two injection runners. The sides of the two cutting blocks that are far apart from each other are used to form the outer surface of the road cone. When the mold is closed, the moving template presses the top plate against the bottom wall of the first sliding groove. A forming cavity for forming two road cones is formed between the two receiving holes, the two conical inserts and the top plate.

[0006] By adopting the above technical solution, after the product is injection molded and the mold is opened, the first drive unit will drive the top plate to move towards the moving template side and drive the two road cones to move towards the moving template side. During the movement of the two road cones, the two cutting blocks will restrict the movement of the glue gate and cut the connection between the glue gate and the two road cones. During the demolding process of the road cones, the glue gate and the two road cones are separated, thereby completing the automatic trimming of the glue gate, so that the road cones can be directly packaged and shipped after production.

[0007] Preferably, the bottom wall of the sliding groove is provided with a plurality of second mounting holes, and a plurality of first mounting holes are respectively opened in the plurality of second mounting holes. The first driving part is a plurality of first springs provided in the plurality of second mounting holes. The plurality of first springs are respectively sleeved on a plurality of guide posts. One end of each of the plurality of first springs abuts against the bottom wall of the top plate and the other end abuts against the bottom wall of the corresponding second mounting hole. When the mold is closed, the plurality of springs are all in a compressed state. When the mold is opened, the plurality of springs push the two top plates to move toward the moving template side, so that the distance from the top surface of the top plate to the moving template is less than the distance from the bottom surface of the two cut pieces to the moving template.

[0008] By adopting the above technical solution, when the mold is opened, the lower mold body will move away from the upper mold body under the control of the injection molding machine. During the process of the lower mold body moving away from the upper mold body, the moving platen will no longer press against the top plate. At this time, the first springs sleeved on the guide pillars will rebound and reset and push the top plate to move towards the moving platen. When the two top plates move, they will push the two road cones towards the moving platen, thereby helping the two road cones to be demolded.

[0009] Preferably, the bottom of both cut blocks is provided with a first inclined surface, and the distance between the two first inclined surfaces gradually decreases from the end closer to the fixed template to the end farther away from the fixed template.

[0010] By adopting the above technical solution, the opening of the two first inclined planes will improve the cutting effect of the two cutting blocks on the glue hole and the road cone, making the interface at the connection between the road cone and the glue hole neat.

[0011] Preferably, each of the two injection runner bottom walls is provided with a first sliding hole along the mold opening direction, and an ejector pin is slidably connected in each of the two first sliding holes. The fixed template is also provided with two control components for controlling the movement of the two ejector pins respectively.

[0012] By adopting the above technical solution, after the two traffic cones and the nozzle are cut by the two cutting blocks, the two control components control the two ejector pins to slide out of the two first sliding holes, so that the two bottom rods push the nozzle located in the two injection channels out of the injection channels, causing the nozzle to fall out of the mold and preventing the nozzle from affecting the production of the next set of traffic cones.

[0013] Preferably, the control component includes a second spring, a limiting block, and a pull rod disposed within the first sliding hole. One end of the second spring abuts against the bottom wall of the ejector pin, and the other end abuts against the bottom wall of the first sliding hole. Both second springs are always in a compressed state. Each of the two ejector pins has a first sliding groove for the limiting block to pass through. Two second sliding grooves are formed on the inner sidewall of the sliding groove, and the two second sliding grooves respectively connect to the two first sliding holes. Two third sliding grooves are formed on the inner sidewall of the top plate. The pull rod is disposed within the third sliding groove, and the two third sliding grooves respectively connect to the two second sliding grooves. One end of the limiting block is slidably connected to the first and second sliding grooves, and the other end is slidably connected to the third sliding groove. Each of the two limiting blocks has a second inclined surface at the end of the first sliding groove. The distance from the second inclined surface to the bottom wall of the corresponding second sliding groove is measured from the top... The slope gradually increases towards the bottom. A third inclined surface is formed on the bottom surface of each of the two first grooves. The inclination angle of each of the two third inclined surfaces is the same as the inclination angle of the second inclined surface on the same side. Two inclined through-grooves are formed on each of the two limiting blocks. The distance from the through-grooves to the bottom wall of the corresponding third groove gradually increases from the top to the bottom. Two pull rods are located within the two through-grooves. In the mold-closed state, the two pull rods are located on the side of the two through-grooves that are far apart from each other. The ends of the two limiting blocks that are far from the third groove abut against the bottom walls of the two second grooves. The distance from the bottom of the two first inclined surfaces to the adjacent ejector pins is greater than the distance from the top surface of the top plate to the bottom of the cutting block. In the mold-open state, the two first inclined surfaces are attached to the two second inclined surfaces. The tops of the two ejector pins extend into two injection channels. The distance from the two ejector pins to the moving mold plate is greater than the distance from the top plate to the moving mold plate.

[0014] By adopting the above technical solution, when the mold opens, the top plate moves towards the moving platen under the push of several first springs. The top plate will drive the two pull rods to move together. When the two pull rods move, they will drive the two limiting blocks to slide into the corresponding third slide groove through the two through slots. When the top surface of the top plate moves to a position higher than the bottom of the two cutting blocks, the second inclined surface of the two limiting blocks moves to contact the two third inclined surfaces. As the two top plates continue to move, the two limiting blocks will continue to slide into the third slide groove. The two second inclined surfaces will continue to move towards the third slide groove. During the movement of the two second inclined surfaces, the two second springs will rebound and reset, thereby pushing the two ejector pins to move out of the two first sliding holes, thereby ejecting the gate located in the two injection channels from the injection channels, thus completing the automatic demolding of the gate. When the mold is closed, the moving platen first contacts the top plate and pushes the top plate back to its original position. During the retraction and reset of the top plate, several first springs are compressed and deformed and return to several second mounting holes. As the two top plates return to the clearance groove, the two pressing rods press against the two limiting blocks, causing the two limiting blocks to move away from the third slide groove. As the two limiting blocks move away from the third slide groove, they press against the two third inclined surfaces through the two second inclined surfaces, causing the two ejector pins to retract and reset into the two first sliding holes and drive the two second springs to compress, preparing for the demolding of the next set of gates.

[0015] Preferably, the top plate is provided with mounting inserts, both of the third sliding grooves are formed on the mounting inserts, both of the third sliding grooves pass through the two mounting inserts, and both of the pull rods are located on the mounting inserts.

[0016] By adopting the above technical solution, the installation and disassembly of the limit block and the pressure rod are facilitated.

[0017] Preferably, the top plate has two clearance holes along the mold opening direction for two conical inserts to pass through. The two opposite outer sidewalls of the sliding groove have two clearance grooves along the mold opening direction perpendicular to the mold. The top plate has an air passage. Several air outlets of the air passage are located on the hole walls of the two clearance holes, and several air inlets of the air passage are all set opposite the clearance grooves.

[0018] By adopting the above technical solution, when the top plate is ejected, the air outlet no longer adheres to the outer wall of the conical insert. At this time, the injection molding machine controls the air pump to pump air into the air inlet in the air channel. The gas will then flow through the air channel from several air inlets into the space between the two cones and the two mounting inserts, thereby separating the two cones from the two mounting inserts, achieving the effect of assisting demolding and facilitating the removal of the cones from the mounting inserts after molding. The clearance groove is designed to facilitate the connection between the air pipe and the air inlet of the air channel.

[0019] Preferably, a plurality of the air outlets are circumferentially equidistantly arranged on the walls of the two clearance holes.

[0020] By adopting the above technical solutions, the effectiveness of gas separation cones and installation inserts can be improved.

[0021] Preferably, the air outlets of the air passage are all inclined upwards.

[0022] By adopting the above technical solution, the direction of gas outlet is guided, thereby improving the gas's auxiliary demolding effect on the road cone.

[0023] The main technical effects of this invention are reflected in the following aspects:

[0024] 1. This invention enables the automatic removal of the glue outlet during demolding of the traffic cone through the cooperation of the top plate and two cutting blocks;

[0025] 2. This invention utilizes the movement of the top plate to drive the movement of two ejector pins, so that after the gate is cut off, it can be ejected from the injection channel by the two ejector pins;

[0026] 3. This invention assists in the demolding of the two road cones by setting up air channels. Attached Figure Description

[0041] The present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this application can be more easily understood and mastered.

[0042] Reference Figures 1-4This embodiment of an automatic injection molding equipment for traffic cones includes an injection molding machine 1 and a traffic cone forming mold 3 mounted on the injection molding machine 1. In this application, the mold opening direction is the X-axis direction. The traffic cone forming mold 3 includes an upper mold body 4 and a lower mold body 5. The upper mold body 4 includes an upper fixed plate 41 and a fixed template 42 fixed on the upper fixed plate 41. The lower mold body 5 includes a lower fixed plate 51 and a movable template 52 fixed on the lower fixed plate 51. A sliding groove 423 is provided along the X-axis direction on the side of the fixed template 42 facing the movable template 52. The sliding groove 423 is U-shaped. Two injection channels 422 for supplying hot melt plastic are also provided along the Y-axis direction on the side of the fixed template 42 facing the movable template 52. The ends of the two injection channels 422 that are close to each other are connected, and the ends of the two injection channels 422 that are far apart from each other are respectively connected to the sliding groove 423. The bottom wall of the sliding groove 423 is provided with four second mounting holes 425 and two through holes 421 along the X-axis direction. The four mounting holes are respectively opened at the four corners of the sliding groove 423. The bottom wall of each of the four second mounting holes 425 is provided with a first mounting hole 424 along the X-axis direction. A guide post 61 is fixedly connected in the first mounting hole 424.

[0043] Reference Figure 2 - As shown in Figure 6, the sliding groove 423 is also equipped with a U-shaped top plate 2 for forming the base 92. The top plate 2 is slidably connected to several guide pillars 61 along the mold opening direction. Two clearance holes 21 are opened on the top plate 2 along the X-axis direction, and the two clearance holes 21 are respectively connected to two through holes 421. The diameter of the two clearance holes 21 gradually increases from the side closer to the moving template 52 to the side farther away from the moving template 52. Two conical inserts 62 for forming the traffic cone are also fixedly connected to the fixed plate. The two conical inserts 62 pass through the two through holes 421 and the two clearance holes 21 respectively and extend out of the moving template 52. The moving template 52 has two receiving holes 521 for cooperating with the conical inserts 62 to produce the traffic cone.

[0044] Reference Figures 2-4 Two clearance grooves 428 are formed on the two opposite outer sidewalls of the sliding groove 423 along the mold opening direction perpendicular to the mold. An air passage 22 is formed inside the top plate 2. Several air outlets of the air passage 22 are located on the walls of the two clearance holes 21 and are all inclined upwards. The air outlets of the air passage 22 on each clearance hole 21 are circumferentially equidistantly distributed, and the four air inlets of the air passage 22 are arranged in pairs directly opposite the clearance grooves 428. The machining holes generated by drilling the air passage 22 are sealed with copper plugs.

[0045] Reference Figure 2 , Figure 3 and Figure 7Two cutting blocks 63 are fixedly connected to the side of the fixed template 42 facing the moving template 52. The two cutting blocks 63 are located above the two injection channels 422 respectively. The sides of the two cutting blocks 63 that are far apart from each other are used to form the outer surface of the road cone. The bottom of the two cutting blocks 63 is provided with a first inclined surface 631. The distance between the two first inclined surfaces 631 gradually decreases from the end closer to the fixed template 42 to the end farther away from the fixed template 42.

[0046] Reference Figures 2-4 The fixed template 42 also has a first driving part 64 for driving the top plate 2 to move towards the moving template 52. The first driving part 64 consists of four first springs 641 installed in several second mounting holes 425. The four first springs 641 are respectively sleeved on four guide posts 61. One end of each of the four first springs 641 abuts against the bottom wall of the top plate 2, and the other end abuts against the bottom wall of the corresponding second mounting hole 425. When the mold is closed, the springs are all in a compressed state. When the mold is opened, the springs push the two top plates 2 towards the moving template 52, so that the distance from the top surface of the top plate 2 to the moving template 52 is less than the distance from the bottom surface of the two cutting blocks 63 to the moving template 52. Two conical inserts 62 for forming traffic cones are also fixedly connected to the upper fixed plate 41. Two through holes 421 are also opened on the bottom wall of the sliding groove 423 along the X-axis direction. The two conical inserts 62 pass through the two through holes 421 and extend out of the moving template 52.

[0047] Reference Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10 Each of the two injection runners 422 has a first sliding hole 426 along the X-axis on its bottom wall. Ejector pins 65 are slidably connected within each of the two first sliding holes 426 along the X-axis. The fixed template 42 also has two control components 7 for controlling the movement of the two ejector pins 65 respectively. The control components 7 include a second spring 71, a limiting block 72, and a pull rod 73, all located within the first sliding hole 426. One end of the second spring 71 abuts against the bottom wall of the ejector pin 65, and the other end abuts against the bottom wall of the first sliding hole 426. Both second springs 71 are always in a compressed state. Each of the two ejector pins 65 has a first sliding groove 651 for the limiting block 72 to pass through. Two second sliding grooves 427 are formed along the Y-axis on the inner side wall of the sliding groove 423, and the two second sliding grooves 427 are respectively connected to the two first sliding holes 426.

[0048] Reference Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10A mounting block 8 is bolted to the bottom of the top plate 2. Two third sliding grooves 81 are formed on the top surface of the mounting block 8 along the X-axis, connecting to two second sliding grooves 427. One end of a limiting block 72 is slidably connected to the first sliding groove 651 and the second sliding groove 427, while the other end is slidably connected to the third sliding groove 81. Both limiting blocks 72 have second inclined surfaces 721 at their ends in the first sliding groove 651. The distance from the second inclined surface 721 to the bottom wall of the corresponding second sliding groove 427 gradually increases from the top to the bottom. Third inclined surfaces 652 are formed on the bottom surfaces of both first sliding grooves 651, with the inclination angles of the two third inclined surfaces 652 being the same as the inclination angle of the second inclined surface 721 on the same side. Two inclined through grooves 722 are formed on each of the two limiting blocks 72, with the distance from the through groove 722 to the bottom wall of the corresponding third sliding groove 81 gradually increasing from the top to the bottom. Two pull rods 73 are fixedly connected to two third slide grooves 81 respectively, and the two pull rods 73 are also located in two through grooves 722 respectively.

[0049] Reference Figure 2 , Figure 3 , Figure 8 , Figures 9-12 In the mold closed state, the two pull rods 73 are located on opposite sides of the two through slots 722, and the ends of the two limit blocks 72 away from the third slide 81 are in contact with the bottom walls of the two second slides 427. The distance between the bottom of the two second inclined surfaces 721 and the adjacent ejector pins 65 is greater than the distance between the top surface of the top plate 2 and the bottom of the cutting block 63. In the mold open state, the two second inclined surfaces 721 are in contact with the two third inclined surfaces 652, and the tops of the two ejector pins 65 extend out of the two injection channels 422. The distance between the two ejector pins 65 and the moving platen 52 is greater than the distance between the top plate 2 and the moving platen 52.

[0050] The specific production process of the device applied for is as follows:

[0051] First, under the control of the injection molding machine 1, the lower mold body 5 moves toward the upper mold body 4 to close the mold. During the mold closing process, the moving platen 52 will first come into contact with the top plate 2 and push the top plate 2 back to its original position. During the back-reset process of the top plate 2, the four first springs 641 are compressed and deformed and return to the second mounting holes 425. During the process of the two top plates 2 returning to the relief groove 428, the two pressing rods will press against the two limiting blocks 72, causing the two limiting blocks 72 to move away from the third slide groove 81. During the process of the two limiting blocks 72 moving away from the third slide groove 81, they will press against the two third inclined surfaces 652 through the two second inclined surfaces 721, thereby causing the two ejector pins 65 to return to their original position in the two first sliding holes 426 and drive the two second springs 71 to compress. Finally, the two ejector pins 65 will retract into the two first sliding holes 426, and the top plate 2 will abut against the bottom wall of the sliding groove 423. A forming cavity for forming two road cones is formed between the two receiving holes 521, the two conical inserts 62 and the top plate 2.

[0052] Then injection molding machine 1 starts to inject plastic. The plastic will flow through two injection channels 422 into two molding cavities. Then injection molding machine 1 enters the pressure holding process stage. After the pressure holding is completed, the two cones are formed. At the same time, the two cones are connected by a glue port, which is located in the two injection channels 422.

[0053] Next, the injection molding machine 1 controls the lower mold body 5 to move away from the upper mold body 4, thereby opening the mold. When the mold opens, the moving platen 52 no longer presses against the top plate 2. Therefore, the four first springs 641 will rebound and push the top plate 2 towards the moving platen 52. When the top plate 2 moves, it will drive the two road cones and the two pressing rods to move towards the moving platen 52. During the movement of the two road cones, the two cutting blocks 63 will restrict the movement of the injection port and cut the connection between the injection port and the two road cones. When the two pulling rods 73 move, they will drive the two limiting blocks 72 to slide into the corresponding third sliding grooves 81 through the two through slots 722. When the top surface of the top plate 2 moves to be flush with the bottom of the two cutting blocks 63, the second inclined surface 721 of the two limiting blocks 72 moves to contact the two third inclined surfaces 652. At the same time, the two cutting blocks 63 cut and separate the injection port and the two road cones.

[0054] Under the action of the four first springs 641, the top plate 2 will continue to move together with the two pressure rods. Under the lifting action of the two pressure rods, the two limit blocks 72 will continue to slide into the third slide groove 81. The two second inclined surfaces 721 will continue to move towards the third slide groove 81. During the movement of the two second inclined surfaces 721, the two second springs 71 will rebound and reset, thereby pushing the two ejector pins 65 to move out of the two first sliding holes 426, thereby ejecting the gate located in the two injection channels 422 out of the injection channels 422, thus completing the automatic demolding of the gate.

[0055] When the top plate 2 is ejected, the air outlet is no longer in contact with the outer wall of the conical insert 62. At this time, the injection molding machine 1 will control the air pump to blow air into the air inlet in the air passage 22. The air will then flow through the air passage 22 from several air inlets into the space between the two cones 91 and the two mounting inserts 8, thereby separating the two road cones from the two mounting inserts 8, achieving the effect of assisting demolding and making it easier to remove the road cones from the mounting inserts 8 after molding. After the two road cones are removed, the injection molding machine 1 will control the mold to close again to perform injection molding of a new set of road cones.

[0056] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
