Description

Technical Field

[0001] The invention relates to the technical field of injection molding, and in particular to an injection molding machine for outdoor PVC wall decorative panels. Background Art

[0002] PVC board, also known as Chevron board or Fron board, is a board made of PVC as the main material. It is extruded and molded. The surface of this board is smooth and flat, and the cross section is honeycomb-shaped. It is light, strong and has good weather resistance. It can partially replace wood and steel. It is suitable for a variety of processes such as engraving, hole turning, painting, bonding, etc.

[0003] An injection molding machine is a molding device used for plastic products. It molds thermoplastics or thermosetting plastics into various shapes through plastic molding molds. During the production process, the injection molding machine first heats the plastic, which is in a molten state after heating, and then injects it into the mold cavity to form the plastic.

[0004] The raw material before melting is granular plastic. Plastic is easy to clump when stored for a long time. The agglomerated raw material is easy to cause blockage during use. At the same time, the outside of the plastic melts first when it melts. At this time, the plastic is in a solid-liquid mixed state, and the raw materials stick to each other. At this time, it is very easy to cause blockage during transportation. Therefore, we proposed an injection molding machine for outdoor PVC wall decorative panels. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an injection molding machine for outdoor PVC wall decoration panels, comprising a bottom plate, a support plate is arranged on the top of the bottom plate, an injection molding mechanism is fixedly connected to the side of the support plate away from the bottom plate, a feeding mechanism is arranged on the side of the injection molding mechanism away from the bottom plate, the injection molding mechanism comprises a shell, the shell is fixedly connected to the side of the support plate away from the bottom plate, an insulation cylinder is fixedly connected to the inner wall of the shell, the insulation cylinder is made of insulation material, the inner wall of the insulation cylinder is fixedly connected to a cylinder, an injection cylinder is fixedly connected to the outer surface of the end of the cylinder, a motor is arranged on the side of the shell away from the injection cylinder, a fixing plate is fixedly connected to the outer surface of the motor, and the fixing plate is fixedly connected to the top of the bottom plate, a rotating shaft is fixedly connected to the side of the motor close to the shell, the rotating shaft is fixedly connected to the output end of the motor and extends to the inside of the cylinder, a feeding screw is slidably connected to the inner wall of the cylinder, a plurality of the feeding screws are arranged below the feeding mechanism, and the feeding screws are fixedly connected to the outer surface of the rotating shaft, and the raw material particles enter the inside of the cylinder from the feeding mechanism The output end of the motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the feeding screw to rotate. The feeding screw is set in a spiral shape, and the granular raw material is transported during rotation. At the same time, several feeding screws are set. When the raw material is between two feeding screws, the feeding screw no longer drives the raw material to be transported. The raw material that has lost the main power and the raw material that is still being transported have relative friction and extrusion, thereby separating the adhered raw materials. Compared with the traditional whole vortex blade, it can separate the bonded raw materials while transporting to avoid blockage. An anti-sticking component is provided on the side of the feeding screw away from the motor, and a heating component is provided on the outside of the anti-sticking component. A limiting flow component is provided on the side of the heating component away from the anti-sticking component, and the anti-sticking component, the heating component and the limiting flow component are all arranged inside the cylinder. The granular raw material is transported to the anti-sticking component, and the heating component heats the raw material. At this time, part of the material outside is melted first, and the anti-sticking component prevents the melted raw materials from sticking to each other and blocking the cylinder. The completely melted raw material is transported to the limiting flow component, and the limiting flow component limits the injection speed of the material to avoid injection and trapped air during injection.

[0006] Furthermore, a sealing plate is rotatably connected to the side of the rotating shaft close to the motor, and the outer surface of the sealing plate is fixedly connected to the inner wall of the cylinder. A wide screw is provided at the interval between the current limiting component and the anti-sticking component, and the inner side of the wide screw is fixedly connected to the rotating shaft, and the outer surface of the wide screw is rotatably connected to the inner wall of the cylinder. The wide screw has a larger pitch and can convey more raw materials at one time. After the raw materials are melted, the resistance is smaller than that of conveying granular raw materials. The wide screw is provided to increase the conveying speed and prevent the melted raw materials from solidifying, thereby further avoiding blockage.

[0007] Furthermore, the anti-sticking component includes stirring teeth, and the stirring teeth are arranged in several groups along the axial direction of the rotating shaft, and each group of the stirring teeth is arranged in several directions along the circumferential direction of the rotating shaft, and the stirring teeth of two adjacent groups are staggered, and the sides of the two adjacent groups of stirring teeth close to each other are fixedly connected with fixed blocks, and a stirring rod is arranged at the interval between the two fixed blocks, and the two ends of the stirring rod are fixedly connected to the sides of the two fixed blocks close to each other, and the stirring rod is bent. When the material is heated, the outside will melt first. At this time, the material is in a state of solid-liquid mixing, and adhesion between the materials is very likely to cause blockage. The rotation of the rotating shaft drives the stirring teeth to rotate, and the rotation of the stirring teeth drives the stirring rod to rotate at the same time. The rotation of the stirring teeth stirs the material to avoid blockage caused by adhesion between the materials, and the stirring rod increases the stirring range. At the same time, due to the bent setting of the stirring rod, the axial materials are mixed while stirring the material, further avoiding adhesion of the material.

[0008] Furthermore, arc grooves are symmetrically provided on both sides of the stirring rod, and the arc grooves are arranged in a V shape. By providing the arc grooves, the contact area between the stirring rod and the material is increased, thereby driving more axial materials to be mixed, further improving the stirring effect, and avoiding material adhesion. At the same time, the cross-section of the arc groove is arranged in a V shape, so that the side of the stirring rod presents two sharp corners, thereby being able to separate the already adhered materials and further avoiding blockage.

[0009] Furthermore, the heating component includes an annular groove, which is arranged at the connection between the cylinder and the insulating cylinder, and the annular groove is opened at the outer surface of the cylinder and the inner wall of the insulating cylinder. The inner wall of the annular groove is fixedly connected with a first heating ring. Several first heating rings are arranged outside the anti-sticking component. A first electric heating wire is fixedly installed inside the first heating ring. The first electric heating wire generates heat, which is transferred to the cylinder through the first heating ring, and then the raw material inside the cylinder is heated. The first heating ring is arranged so that the outside of the cylinder is evenly heated, so that the raw material is evenly melted.

[0010] Furthermore, a second heating ring is fixedly connected to the inner wall of the ring groove, and the second heating ring is arranged outside the wide screw blade, and a second heating wire is fixedly installed inside the second heating ring. Copper plates are symmetrically arranged at both ends of the second heating ring, and the copper plates are fixedly connected to the outer surface of the end of the second heating ring. The second heating wire generates heat, which is transferred to the cylinder through the second heating ring, thereby heating the raw material inside the cylinder. At the same time, the symmetrically arranged copper plates conduct heat and heat up, and keep the liquid material transported by the wide screw blade warm, so as to avoid the raw material from solidifying away from the first heating ring and the second heating ring, thereby ensuring that the material can be smoothly injected.

[0011] Furthermore, the flow limiting assembly includes a ring plate, the outer surface of the ring plate is fixedly connected to the inner wall of the cylinder, the inner wall of the ring plate is fixedly connected to the flow limiting cylinder, the inner wall of the flow limiting cylinder is fixedly connected with a rib plate, the end of the rib plate away from the flow limiting cylinder is fixedly connected to the cylinder, the inner wall of the cylinder is fixedly connected with a spring, the end of the spring away from the cylinder is fixedly connected to the flow limiting plate, and the flow limiting plate is adapted to the flow limiting cylinder, the end of the ring plate away from the rotating shaft is fixedly connected to a cone plate, the surface of the cone plate is evenly provided with drainage holes, the melted raw material is transported to the flow limiting assembly, the solution passes through the gap between the flow limiting cylinder and the cylinder, the solution squeezes the flow limiting plate, the spring is stretched, and the original spring is tightly attached to the flow limiting cylinder and the flow limiting plate under the action of the spring elastic force. The gap, the melted raw material enters the gap between the ring plate and the flow limiting cylinder, and then the solution enters the injection cylinder through the drainage hole, and is finally injected into the prepared mold through the injection cylinder. By setting the flow limiting cylinder and the flow limiting plate to match, the raw material can only be injected outward from the device, limiting the reflux of the melted raw material, thereby ensuring the volume of the injected raw material and the strength of the wall panel after molding. The flow limiting component can also limit the outflow speed of the raw material, thereby ensuring that the raw material is completely melted and further improving the strength of the wall panel after molding. At the same time, by evenly arranging the drainage holes, the raw material can be evenly poured out from all sides of the cone plate, thereby avoiding the drainage holes below being covered by the raw material and the raw material continuing to pour out to cause tumbling, and avoiding bubbles in the tumbling viscous raw material that affect the molding quality.

[0012] Furthermore, the feeding mechanism includes a mounting block, which is fixedly connected to the outer surface of the cylinder, and the mounting block passes through the insulation cylinder and the outer shell and extends to the side away from the bottom plate. A funnel is fixedly connected to the inner wall of the mounting block, a recessed cylinder is fixedly connected to the side of the funnel away from the mounting block, and a top plate is fixedly connected to the side of the recessed cylinder away from the funnel. A feeding hole is provided on the outer surface of the top plate, and the granular raw material is put in through the feeding hole, and the granular raw material passes through the recessed cylinder and the funnel in turn and finally enters the interior of the cylinder. By setting the funnel, the raw material is not easy to spill during feeding, and the recessed cylinder is set on the top of the funnel, so that the elastic raw material is difficult to fly out of the feeding hole when it falls and rebounds, thereby avoiding waste of raw materials.

[0013] Furthermore, a support frame is fixedly connected to a side of the top plate away from the mounting block, a motor is fixedly connected to an inner wall of the support frame, a stirring shaft is fixedly connected to an end of the motor close to the top plate, and the stirring shaft is fixedly connected to an output end of the motor and extends through the top plate to the bottom of the funnel, a wave plate is fixedly connected to an outer surface of the stirring shaft, a plurality of wave plates are arranged along the circumference and axial direction of the stirring shaft, and the wave plates arranged along the axial direction of the stirring shaft are staggered, a stabilizing block is fixedly connected to an end of the wave plate away from the stirring shaft, and the stabilizing block is slidably connected to the inner wall of the funnel, and when the raw materials are roughly added to the bottom, the stirring shaft is fixedly connected to the stirring shaft. When passing the stabilizing block, the motor is started, and the output end of the motor drives the stirring shaft to rotate, and the rotation of the stirring shaft drives the wave plate to rotate, and the rotation of the wave plate drives the stabilizing block to rotate along the inner wall of the funnel, so as to stir the raw materials. At the same time, several wave plates arranged along the axial direction are staggered, so that when the wave plates contact the agglomerated raw materials, they continuously move the agglomerated raw materials at the bottom, so that they gradually move upward and finally contact with the circumferentially arranged wave plates, so as to avoid the agglomerated raw materials being located at the bottom of the funnel and causing blockage. At the same time, the circumferentially arranged wave plates are more dense, and can stir and impact the agglomerated raw materials when rotating to disperse them, further avoiding blockage of the funnel.

[0014] Furthermore, a sleeve is provided at one end of the stirring shaft away from the motor, the inner wall of the sleeve is fixedly connected to the outer surface of the stirring shaft, a plurality of stirring blades are fixedly connected to the outer surface of the sleeve, the side of the stirring blades away from the sleeve is slidably connected to the inner wall of the funnel, and the stirring blades are bent, the rotation of the stirring shaft drives the sleeve to rotate, the sleeve drives the stirring blades to rotate, stirring the raw materials at the bottom of the funnel, so that there is always a gap between the raw materials and the funnel, so that the raw materials can pass smoothly, and at the same time, the stirring blades are bent, and drive the raw materials to be transported downward while stirring, thereby avoiding clogging of the bottom of the funnel.

[0015] The present invention has the beneficial effects:

[0016] The present invention provides a feeding screw with multiple feeding screws. When the raw material is between two feeding screws, the feeding screws no longer drive the raw material to be transported. Relative friction and extrusion occur between the raw material that has lost its main driving force and the raw material that is still being transported, thereby separating the adhered raw materials. Compared with the traditional whole vortex blade, the adhered raw materials can be separated while being transported to avoid blockage.

[0017] The present invention provides a stirring assembly, and the rotation of the rotating shaft drives the stirring teeth to rotate. The rotation of the stirring teeth drives the stirring rod to rotate at the same time. The stirring teeth rotate to stir the material to avoid blockage caused by adhesion between the materials. The stirring rod increases the stirring range. At the same time, due to the curved setting of the stirring rod, the axial materials are mixed while stirring the materials, further avoiding material adhesion. By providing an arc groove, the contact area between the stirring rod and the material is increased, thereby driving more axial materials to mix, further improving the stirring effect, and avoiding material adhesion. At the same time, the cross-section of the arc groove is set to be V-shaped, so that the side of the stirring rod presents two sharp angles, so that the already adhered materials can be separated to further avoid blockage.

[0018] The present invention provides a flow limiting component, and provides a flow limiting tube adapted to a flow limiting plate, so that the raw material can only be injected outward from the device, and the backflow of the molten raw material is limited, thereby ensuring the volume of the injected raw material and the strength of the wall panel after molding. The flow limiting component can also limit the outflow speed of the raw material, thereby ensuring that the raw material is completely melted, and further improving the strength of the wall panel after molding. At the same time, by evenly arranging drainage holes, the raw material can be evenly poured out from all sides of the cone plate, thereby avoiding the drainage holes below being covered by the raw material and continuing to pour out to cause tumbling, and avoiding bubbles generated inside the tumbling viscous raw material to affect the molding quality.

[0019] The present invention provides a feeding mechanism, and the rotation of the stirring shaft drives the wave plate to rotate, and the rotation of the wave plate drives the stabilizing block to rotate along the inner wall of the funnel, so as to stir the raw materials.

At the same time, the circumferentially arranged wave plates are more dense, and can stir and impact the agglomerated raw materials when rotating to disperse them, further avoiding blockage of the funnel.

The feeding screw 311 is set in a spiral shape. When rotating, the granular raw material is transported. At the same time, a plurality of feeding screws 311 are set. When the raw material is between two feeding screws 311, the feeding screw 311 no longer drives the raw material to be transported between them. The raw material that has lost the main power and the raw material that is still being transported are relatively rubbed and squeezed, thereby separating the adhered raw materials.

By setting the funnel 42, the raw material is not easy to spill during feeding. The recessed cylinder 43 is set on the top of the funnel 42, so that the elastic raw material is difficult to fly out of the feeding hole 45 when it falls and rebounds, thereby avoiding the waste of raw materials.

[0041] A support frame 46 is fixedly connected to one side of the top plate 44 away from the mounting block 41, a motor 47 is fixedly connected to the inner wall of the support frame 46, a stirring shaft 48 is fixedly connected to one end of the motor 47 close to the top plate 44, and the stirring shaft 48 is fixedly connected to the output end of the motor 47, and extends through the top plate 44 to the bottom of the funnel 42, a wave plate 49 is fixedly connected to the outer surface of the stirring shaft 48, a plurality of wave plates 49 are arranged along the circumference and axial direction of the stirring shaft 48, and the wave plates 49 arranged along the axial direction of the stirring shaft 48 are staggered, a stabilizing block 410 is fixedly connected to one end of the wave plate 49 away from the stirring shaft 48, and the stabilizing block 410 is slidably connected to the inner wall of the funnel 42, and when the raw materials are roughly added to the stabilizing block 410, the stabilizing block 410 is slidably connected to the inner wall of the funnel 42. When block 410 is turned on, motor 47 is started, and the output end of motor 47 drives stirring shaft 48 to rotate, and the rotation of stirring shaft 48 drives wave plate 49 to rotate, and the rotation of wave plate 49 drives stabilizing block 410 to rotate along the inner wall of funnel 42, so as to stir the raw materials. At the same time, several wave plates 49 arranged along the axial direction are arranged in a staggered manner, so that when wave plates 49 contact the agglomerated raw materials, the agglomerated raw materials at the bottom are continuously moved to gradually move upward, and finally contact with the circumferentially arranged wave plates 49, so as to avoid the agglomerated raw materials being located at the bottom of funnel 42 and causing blockage. At the same time, the circumferentially arranged wave plates 49 are more dense, and can stir and impact the agglomerated raw materials when rotating to disperse them, thereby further avoiding blockage of funnel 42.

[0042] A sleeve 411 is provided at one end of the stirring shaft 48 away from the motor 47, and the inner wall of the sleeve 411 is fixedly connected to the outer surface of the stirring shaft 48. A number of stirring blades 412 are fixedly connected to the outer surface of the sleeve 411. The side of the stirring blades 412 away from the sleeve 411 is slidably connected to the inner wall of the funnel 42, and the stirring blades 412 are bent. The rotation of the stirring shaft 48 drives the sleeve 411 to rotate, and the sleeve 411 drives the stirring blades 412 to rotate, stirring the raw materials at the bottom of the funnel 42, so that there is always a gap between the raw materials and the funnel 42, so that the raw materials can pass smoothly. At the same time, the stirring blades 412 are bent, and while stirring, they drive the raw materials to be transported downward, thereby avoiding clogging of the bottom of the funnel 42.

[0043] When in use, firstly, the material is loaded, and the granular raw material is put in through the feeding hole 45, and the granular raw material passes through the sunken cylinder 43 and the funnel 42 in turn, and finally enters the inside of the cylinder 33. When the raw material is added to approximately cover the stabilizing block 410, the motor 47 is started, and the output end of the motor 47 drives the stirring shaft 48 to rotate, and the stirring shaft 48 rotates to drive the wave plate 49 to rotate, and the wave plate 49 rotates to drive the stabilizing block 410 to rotate along the inner wall of the funnel 42, and the stirring shaft 48 rotates to drive the sleeve 411 to rotate, and the sleeve 411 drives the stirring blade 412 to rotate, and the raw material at the bottom of the funnel 42 is stirred, so that there is always a gap between the raw material and the funnel 42, so that the raw material can pass smoothly;

[0044] The raw material particles enter the cylinder 33 from the feeding mechanism 4, and the output end of the motor 36 drives the rotating shaft 310 to rotate. The rotation of the rotating shaft 310 drives the feeding screw 311 to rotate. The feeding screw 311 is set in a spiral shape. When rotating, the granular raw material is transported. The granular raw material is transported to the anti-sticking component 37. The heating component 38 heats the raw material. The rotation of the rotating shaft 310 drives the stirring teeth 371 to rotate. The stirring teeth 371 rotates and drives the stirring rod 373 to rotate at the same time. The stirring teeth 371 rotate to stir the material. The rotating shaft 310 rotates and drives the stirring rod 373 to rotate. The stirring teeth 371 rotate to stir the material. The rotation of 10 drives the wide screw blade 313 to rotate, driving the melted raw material to be transported to the flow limiting component 39, and the solution passes through the gap between the flow limiting tube 394 and the cylinder 396. The solution squeezes the flow limiting plate 398, and the spring 397 is stretched. A gap is originally formed between the flow limiting tube 394 and the flow limiting plate 398 under the elastic force of the spring 397. The melted raw material enters the gap between the ring plate 391 and the flow limiting tube 394, and then the solution enters the injection barrel 34 through the drainage hole 393, and is finally injected into the prepared mold through the injection barrel 34.
