Description

Technical Field

[0001] This utility model relates to the field of flooring production, and in particular to an injection molding machine for producing plastic flooring. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics, apply high pressure to the molten plastics, and make them eject and fill the mold cavity. Injection molding machines can also be used for the production of plastic base plates.

[0003] A search revealed Chinese Patent Publication No. CN217144696U, which discloses an injection molding die for WPC flooring production. This patent includes a first die and a second die. The first die has an injection hole on one side and a material cutting mechanism extending into the injection hole. A first cooling mechanism is located inside the first die, and a second cooling mechanism is located inside the second die. The material cutting mechanism includes an injection tube located on one side of the first die and extending into the injection hole. A double-sided cutter is fixed inside the injection tube. This device drives the injection tube via a driving mechanism. The rotation of the injection tube drives the double-sided cutter to cut off the connection between the residual material inside the injection tube and the injection molded product. This results in a smooth, burr-free injection area, improving the overall aesthetics and preventing injuries to workers caused by burrs. In existing injection molding machines used for producing plastic flooring, the large length, width, and height ratios of the flooring mean that using a single tube for injection molding can lead to uneven structures and affect the final molding effect. Existing technology cannot avoid uneven distribution during the injection process, causing internal stress in the flooring and affecting the quality of the injection molding. Utility Model Content

[0004] The purpose of this invention is to provide an injection molding machine for producing plastic flooring in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An injection molding machine for producing plastic flooring includes an extrusion cylinder with a feeding pipe fixedly connected to it. A rotating mechanism is installed inside the extrusion cylinder, including an auger shaft rotatably connected inside the extrusion cylinder. An electric motor is fixedly connected to the center of one end of the extrusion cylinder, and the output end of the electric motor is fixedly connected to the auger shaft. An extrusion head is fixedly connected to the end of the extrusion cylinder away from the electric motor. A connecting mechanism is installed on the extrusion head, including a connector fixedly connected to the connector. A conveyor box is fixedly connected to the connector. Several annularly arranged distribution plates are fixedly connected to the side of the conveyor box away from the connector. An injection tube is fixedly connected to the end of the distribution plate away from the conveyor box. A vibration mechanism is installed on the conveyor box to vibrate the distribution plates and the injection tube.

[0007] Preferably, the vibration mechanism includes several fixed plates, which are fixedly connected to several material distribution plates. The fixed plates have mounting grooves, and conical blocks are fixedly installed in the mounting grooves. The vibration mechanism also includes a turntable. A connecting rod is fixedly connected to the end of the auger shaft away from the motor. The turntable is fixedly connected to the connecting rod. The turntable is movably installed in the mounting grooves, and several impact heads are slidably connected to the side of the turntable.

[0008] Preferably, a spring is installed between the turntable and the impact head.

[0009] Preferably, the conveyor box has an inner cavity that is connected to the extrusion head, and a number of discharge slots are provided on the side of the conveyor box away from the connector, each discharge slot being rectangular.

[0010] Preferably, several material distribution plates are arranged in a ring, the material distribution plates are set at the position of the conveyor box, the material distribution plates are connected to the conveyor box through the discharge groove, and the injection tubes are evenly distributed in a straight line on the material distribution plates.

[0011] Preferably, a lifting frame is fixedly connected to the top of the extrusion cylinder, and a support frame is fixedly connected to the bottom of the extrusion cylinder.

[0012] The beneficial effects are as follows: By setting up a connecting mechanism and a vibration mechanism, the thermoplastic raw material flowing out of the extruder is guided into the distribution plate by several distribution plates set on the conveyor box, and then injected into the mold through each injection tube.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 1 — Figure 7 As shown, an injection molding machine for producing plastic flooring includes an extrusion cylinder 101. A feeding pipe 102 is bolted to the extrusion cylinder 101. The process of hot-melt plastic raw material entering the extrusion cylinder 101 through the feeding pipe 102 can be referred to Chinese Patent No. CN217047276U, which is prior art and will not be described in detail here. A rotating mechanism is provided inside the extrusion cylinder 101, including an auger shaft 201, which is rotatably connected inside the extrusion cylinder 101. A motor 202 is bolted to the center of one end of the extrusion cylinder 101. The output end of the motor 202 is connected to the auger shaft 201 through a coupling. An extrusion head 105 is bolted to the end of the extrusion cylinder 101 away from the motor 202. A connecting mechanism is provided on the extrusion head 105. The structure includes a connector 301, which is bolted to an extrusion head 105. A conveyor box 302 is bolted to the connector 301. Several annularly arranged distribution plates 303 are bolted to the side of the conveyor box 302 away from the connector 301. An injection tube 304 is bolted to the end of the distribution plate 303 away from the conveyor box 302. In the actual injection molding process, the injection tube 304 is connected to one side of the mold. See Chinese Patent Publication No. CN217144696U for details. The structure connected to the first mold described therein is equivalent to the injection tube 304 in this device, which plays the role of introducing hot melt plastic into the mold. A vibration mechanism is provided on the conveyor box 302 to make the distribution plate 303 and the injection tube 304 vibrate.

[0027] In this embodiment, the vibration mechanism includes four fixed plates 401 forming a square area. The fixed plates 401 are welded to each of the material distribution plates 303. An installation groove 402 is provided in each fixed plate 401, and a conical block 403 is fixedly installed in the installation groove 402. The vibration mechanism also includes a turntable 404. A connecting rod 203 is bolted to the end of the auger shaft 201 away from the motor 202. The connecting rod 203 is rotatably connected to the conveyor box 302 and passes through the conveyor box 302 to the outside. The turntable 404 is bolted to the connecting rod 203. The turntable 404 is movably disposed within the installation groove 402. Several impact heads 405 are slidably connected to the side of the turntable 404. A spring 406 is installed between the turntable 404 and the impact heads 405. 06 During the impact of the impact head 405 and the conical block 403, the impact head 405 is reset. The extrusion cylinder 101, extrusion head 105, connecting head 301, conveying box 302, and distribution plate 303 in this device can all be covered with heat insulation material to prevent the temperature of the hot melt plastic from dropping too quickly. When the motor 202 drives the auger shaft 201 to rotate, the connecting rod 203 rotates with the auger shaft 201. The connecting rod 203 drives the turntable 404 to rotate. When the turntable 404 drives each impact head 405 to rotate, the impact head 405 impacts the conical block 403 in the fixed plate 401, causing the fixed plate 401 and the distribution plate 303 to vibrate. This helps to improve the flow of the hot melt plastic in the distribution plate 303 and the injection tube 304, and improve the uniformity of injection molding.

[0028] In this embodiment, an inner cavity is formed inside the conveying box 302 and is connected to the extrusion head 105. Several discharge slots 305 are provided on the side of the conveying box 302 away from the connector head 301, and each discharge slot 305 is rectangular.

[0029] In this embodiment, several material distribution plates 303 are arranged in a ring. The material distribution plates 303 are located at the position of the conveying box 302. The material distribution plates 303 are connected to the conveying box 302 through the discharge groove 305. The injection tubes 304 are evenly distributed in a straight line on the material distribution plates 303.

[0030] In this embodiment, a lifting frame 103 is bolted to the top of the extrusion cylinder 101, and a support frame 104 is bolted to the bottom of the extrusion cylinder 101.

[0031] Working principle: When using this device, the motor 202 is turned on, and the hot-melt plastic flooring material is introduced into the extrusion cylinder 101 through the feeding pipe 102. The motor 202 drives the auger shaft 201 to rotate, which moves the hot-melt plastic in the extrusion cylinder 101 towards the extrusion head 105. After passing through the extrusion head 105, the hot-melt plastic enters the conveying box 302 through the connector 301. The conveying box 302 is filled with hot-melt plastic, which then passes through the discharge slots 305 and is dispersed into the distribution plate 303. Finally, it is injected into the mold through the injection pipe 304. In the process, the injection mold position is similar to the shape of the floor, which is conducive to improving the injection molding effect and finally completing the injection molding operation. When the auger shaft 201 rotates, the connecting rod 203 rotates with the auger shaft 201. The connecting rod 203 drives the turntable 404 to rotate. When the turntable 404 drives each impact head 405 to rotate, the impact head 405 impacts the conical block 403 in the fixed plate 401, causing the fixed plate 401 and the distribution plate 303 to vibrate, improving the flow of hot melt plastic in the distribution plate 303, and further improving the uniformity of injection into the mold by the injection tube 304.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
