[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0003] Existing injection molding machines usually add plastic particles into the injection device of the injection molding machine, and perform injection molding through the heating device and the pushing device in the injection device. However, since the plastic particles are directly put in and heated, the melting efficiency during heating is low, the melting time is long, and more energy is consumed. In addition, the added plastic particles sometimes contain larger particles and cannot be completely melted, affecting the injection molding effect and the quality of the finished product.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] An embodiment of a fully melt injection molding device of the present invention is as follows Figures 1 to 9 As shown, a fully molten injection molding device includes a bracket 100 , an injection molding mechanism, a driving mechanism and a mold mechanism 110 .

[0032] The injection molding mechanism includes an injection molding outer tube 200, an injection molding inner tube 300, an injection molding shaft 400, an injection molding slider 402 and a transmission assembly. The injection molding outer tube 200 is provided with a feed port 201, and a plurality of first heating blocks 202 are provided on the outer peripheral wall of the injection molding outer tube 200. The injection molding outer tube 200 includes a first end and a second end, and a nozzle 203 is provided at the first end of the injection molding outer tube 200.

[0033] The injection molding inner tube 300 is movably arranged inside the injection molding outer tube 200, and a first injection molding dragon 302 is fixedly arranged on the outer peripheral wall of the injection molding inner tube 300. A plurality of melting holes 303 are opened on the peripheral wall of the injection molding inner tube 300, and the diameter of the melting holes 303 gradually increases along the direction from the second end to the first end of the injection molding outer tube 200. The injection molding inner tube 300 is sleeved on the injection molding shaft 400, and a second injection molding dragon 405 is fixedly arranged on the outer peripheral wall of the injection molding shaft 400. The rotation direction of the first injection molding dragon 302 and the second injection molding dragon 405 are opposite. An injection molding pusher 401 is arranged at one end of the injection molding shaft 400, and a stopper 409 is also arranged at the same end. The injection molding slider 402 is sleeved on the injection molding shaft 400 and is located between the injection molding pusher 401 and the stopper 409. The injection molding slider 402 is a transition fit with the injection molding outer tube 200. The other end of the injection molding shaft 400 is connected to the injection molding inner tube 300 through a transmission assembly.

[0034] The driving mechanism includes a first driving assembly and a second driving assembly, wherein the first driving assembly is used to drive the injection shaft 400 to rotate, and the second driving assembly is used to drive the injection shaft 400 to move. The mold mechanism 110 is used to complete injection molding.

[0035] In this embodiment, the injection molding shaft 400 includes a straight shaft and a tapered shaft, the tapered shaft is close to the first end of the injection molding outer tube 200, and the diameter of the tapered shaft gradually increases along the direction from the second end to the first end of the injection molding outer tube 200. The injection molding inner tube 300 includes a straight tube and a tapered tube, the tapered tube is close to the first end of the injection molding outer tube 200, and the diameter of the tapered tube gradually increases along the direction from the second end to the first end of the injection molding outer tube 200. One end of the injection molding inner tube 300 and the first end of the injection molding outer tube 200 are matched without clearance. When extrusion is performed, the maximum extrusion effect is at the tapered shaft and the tapered tube. When the material is difficult to melt, the tapered shaft and the tapered tube are located away from the feed port 201, so that the difficult-to-melt material can be extruded after a longer heating time at the tapered shaft and the tapered tube, so as to achieve a better extrusion utilization rate. When the material is easier to melt, the conical shaft and the conical tube are positioned close to the feed port 201, so that better extrusion utilization can be achieved when the material reaches the conical shaft and the conical tube.

[0036] In this embodiment, if Figure 3 and Figure 5As shown, the first coupling 408 and the spline shaft 204 are sequentially arranged at one end of the injection shaft 400 close to the second end of the injection outer tube 200. The first driving assembly includes a ball spline driving ring 205, a ball spline motor 206 and a ball spline belt 207. The ball spline driving ring 205 is sleeved on the spline shaft 204 and is splined with the spline shaft 204. One end of the ball spline belt 207 is sleeved on the ball spline driving ring 205, and the other end of the ball spline belt 207 is sleeved on the output shaft of the ball spline motor 206. When the ball spline motor 206 is started, the ball spline motor 206 drives the ball spline driving ring 205 to rotate through the ball spline belt 207, and then drives the spline shaft 204 to rotate, thereby driving the injection shaft 400 to rotate.

[0037] In this embodiment, if Figure 3 As shown, the second driving assembly includes a hydraulic cylinder 209 and a second coupling 208. The second coupling 208 is disposed on the spline shaft 204, and the extension end of the hydraulic cylinder 209 is fixedly connected to the spline shaft 204. When the hydraulic cylinder 209 is started, the hydraulic cylinder 209 drives the spline shaft 204 to move, and drives the injection molding inner tube 300 and the injection molding shaft 400 to move toward the first end or the second end of the injection molding outer tube 200.

[0038] In this embodiment, if Figure 6 As shown, the end of the injection molding inner tube 300 close to the second end of the injection molding outer tube 200 is provided with a gear ring 301, and the transmission assembly includes a pinion 403 and a large gear 404. The large gear 404 is fixedly provided at the end of the injection molding shaft 400 close to the second end of the injection molding outer tube 200, and the pinion 403 is meshed with the gear ring 301 and the large gear 404. The rotation of the injection molding shaft 400 drives the large gear 404 to rotate, and the large gear 404 drives the gear ring 301 to rotate through the pinion 403, thereby driving the injection molding inner tube 300 to rotate, so that the rotation directions of the injection molding inner tube 300 and the injection molding shaft 400 are opposite.

[0039] In this embodiment, if Figure 1 As shown, the mold mechanism 110 includes a mold movement mechanism 111 and a fixed template 112. The mold movement mechanism 111 includes a driving motor, a pulley, a push rod and a belt. The pulley is rotatably arranged in the bracket 100, one end of the push rod is threadedly matched with the pulley, and a push plate is installed at the other end of the push rod. A guide rod is arranged through the four corners of the push plate, and a fixed template 112 is arranged at one end of the guide rod. The injection mold is installed between the push plate and the fixed template 112. One end of the belt is connected to the output shaft of the driving motor, and the other end of the belt is connected to the pulley. A conical feed port is arranged on the fixed template 112, and the material enters the fixed template 112 after passing through the conical feed port.

[0040] In this embodiment, if Figure 5As shown, second heating blocks 407 are also provided at both ends of the injection molding shaft 400. The second heating blocks 407 heat the injection molding shaft 400 so that the material inside the injection molding inner tube 300 will not harden, thereby achieving a heat preservation effect.

[0041] In this embodiment, if Figure 7 As shown, a limiting block 304 is fixedly provided at one end of the injection molding inner tube 300 close to the second end of the injection molding outer tube 200, and a limiting groove is provided on the limiting block 304. A limiting baffle 406 is fixedly provided at one end of the injection molding shaft 400 close to the second end of the injection molding outer tube 200, and the limiting baffle 406 is arranged in the limiting groove. The limiting baffle 406 fits with the limiting block 304 to achieve an axial limiting effect, so that the injection molding inner tube 300 and the injection molding shaft 400 can move synchronously in the axial direction.

[0042] In this embodiment, if Figure 7 As shown, the injection pusher 401 is conical, and the injection pusher 401 is installed at the conical feed port, and multiple channels are provided on the injection pusher 401. The material in the injection shaft 400 is transported by the second injection dragon 405 to the end of the injection shaft 400 close to the first end of the injection outer tube 200, passes through the gap between the stopper 409 and the injection slider 402, and finally reaches the nozzle 203 through the channel on the injection pusher 401. The injection shaft 400 is pushed to move, so that the material passes through the nozzle 203 and the conical feed port and enters the fixed template 112.

[0043] In this embodiment, if Figure 2 As shown, a fully melted injection molding device also includes a supporting mechanism, which includes two injection molding tube support plates 101. The injection molding tube support plates 101 are installed on the bracket 100. The upper ends of the injection molding tube support plates 101 are against the injection molding outer tube 200, and the two injection molding tube support plates 101 are parallel to each other.

[0044] Working process: start the first heating block 202 and the second heating block 407, and put the material into the injection molding outer tube 200 from the feed port 201. Since the first heating block 202 heats the injection molding outer tube 200, the material will gradually become a molten state after entering the injection molding outer tube 200.

[0045] The ball spline motor 206 is started, and the ball spline motor 206 drives the ball spline drive ring 205 to rotate through the ball spline belt 207, and then drives the spline shaft 204 to rotate, thereby driving the injection molding shaft 400 to rotate. The rotation of the injection molding shaft 400 drives the large gear 404 to rotate, and the large gear 404 drives the gear ring 301 to rotate through the small gear 403, thereby driving the injection molding inner tube 300 to rotate. The rotation directions of the injection molding inner tube 300 and the injection molding shaft 400 are opposite. Since the rotation directions of the first injection molding dragon 302 and the second injection molding dragon 405 are opposite, the first injection molding dragon 302 and the second injection molding dragon 405 can both transport the material from the second end to the first end of the injection molding outer tube 200.

[0046] Because of the uneven size of the materials, small materials can become molten after a short period of heating, while large materials need to be heated for a longer time to reach a molten state. After the materials enter the injection molding outer tube 200, the materials travel the corresponding path on the first injection molding dragon 302, and the materials that meet the diameter of the melting hole 303 enter the injection molding inner tube 300 and come to the second injection molding dragon 405. The large materials take a longer path on the first injection molding dragon 302 and come to the tapered shaft and the tapered tube. After being squeezed by the tapered shaft and the tapered tube, they enter the injection molding inner tube 300 through the melting hole 303. The materials that come to the injection molding inner tube 300 are transferred to the end of the injection molding shaft 400 near the first end of the injection molding outer tube 200 under the action of the second injection molding dragon 405. In this way, the materials of different sizes can be heated to the same degree, and the small materials will not be overheated, and the large materials will not be heated incompletely.

[0047] The second heating block 407 heats the injection molding shaft 400 so that the material inside the injection molding inner tube 300 will not harden, thus achieving a heat preservation effect. The material inside the injection molding shaft 400 is transported by the second injection molding dragon 405 to the end of the injection molding shaft 400 close to the first end of the injection molding outer tube 200, passes through the gap between the stopper 409 and the injection molding slider 402, and finally reaches the nozzle 203 through the channel on the injection molding pusher 401. When the material fills the nozzle 203, the hydraulic cylinder 209 is started, and the hydraulic cylinder 209 drives the spline shaft 204 to move, and drives the injection molding inner tube 300 and the injection molding shaft 400 to move toward the first end of the injection molding outer tube 200.

[0048] Since the injection slider 402 and the injection outer tube 200 are in transitional fit, when the injection shaft 400 moves toward the first end of the injection outer tube 200, the injection slider 402 contacts the stopper 409 and is pushed by the injection shaft 400 to move synchronously with the injection shaft 400, so that the space between the injection slider 402 and the injection pusher 401 is sealed. The injection shaft 400 is pushed to move, so that the material passes through the nozzle 203 and enters the fixed template 112, and the injection molding is completed after the mold mechanism 110 is shaped, cooled and demolded. Then, the hydraulic cylinder 209 is started again, and the hydraulic cylinder 209 drives the spline shaft 204 to move, and drives the injection inner tube 300 and the injection shaft 400 to move toward the second end of the injection outer tube 200, and continues the next work.

[0049] When extruding, the maximum extrusion effect is at the conical shaft and conical tube. When the material is difficult to melt, that is, when there are more large materials, the conical shaft and conical tube are located away from the feed port 201, so that the difficult-to-melt material can be heated for a longer time before reaching the conical shaft and conical tube for extrusion, so as to achieve a better extrusion utilization rate. When the material is easier to melt, that is, when there are more small materials, the conical shaft and conical tube are located close to the feed port 201, so that when the material reaches the conical shaft and conical tube, a better extrusion utilization rate can be obtained, and the problem of material residue can be better solved.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
