Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding feeders, and in particular relates to an ultra-high molecular plastic injection molding feeder. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. The commonly used blending oil plastic bottles (barrels) and laundry detergent plastic bottles in life are all produced by injection molding equipment using ultra-high molecular plastic raw materials.

[0003] The commonly used injection molding machine has a feeder composed of a storage barrel and a hot melt feed barrel. When in use, the material enters the hot melt feed barrel from the storage barrel, is heated and melted while being conveyed forward, and is finally injected into the injection mold. When the mold is full, the material stops conveying and waits for the material in the mold to cool and be demolded. During this process, the material is in a stationary state in the feed barrel, which can easily cause uneven material temperature. When it is directly injected into the mold when used again, it can easily affect the quality of the finished product. Utility Model Content

[0004] The purpose of the utility model is to provide an ultra-high molecular plastic injection molding feeder, which can make the material circulate after the injection molding is completed, avoiding the temperature of the material to drop when the liquid is not injected, resulting in uneven temperature of the material liquid, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ultra-high molecular plastic injection molding feeder, comprising a feed barrel and an opening and closing component, the feed barrel comprising a hot melt cylinder body, the side wall of the hot melt cylinder body is symmetrically provided with through cavities, both ends of the through cavity are provided with through holes penetrating the side wall of the hot melt cylinder body, there are four opening and closing components, the four opening and closing components are all arranged on the side wall of the hot melt cylinder body, the four opening and closing components are respectively arranged corresponding to the four through holes, the inside of the feed barrel is provided with a feeding component, and the outer wall of the feed barrel is provided with a storage component.

[0006] Furthermore, one end of the hot melt cylinder is fixedly connected to a conical head.

[0007] Furthermore, the opening and closing component includes a plug slidably connected to the inside of the through hole and a shell fixedly connected to the outer wall of the hot melt cylinder, one end of the shell is fixedly connected to a hydraulic rod, and one end of the hydraulic rod is fixedly connected to one side of the plug.

[0008] Furthermore, one end of the plug is symmetrically provided with air holes.

[0009] Furthermore, the material storage component includes a material storage barrel, the bottom end of the material storage barrel is fixedly connected to a conical bucket, the bottom end of the conical bucket is fixedly connected to a material delivery pipe, and the bottom end of the material delivery pipe is fixedly connected to the side wall of the hot melt cylinder.

[0010] Furthermore, a valve is installed on the feed conveying pipe.

[0011] Furthermore, the feeding component includes a spiral rod rotatably connected to the inside of the hot melt cylinder, one end of the hot melt cylinder is fixedly connected to a reduction motor, and the output shaft of the reduction motor is fixedly connected to one end of the spiral rod.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when injection molding is carried out, the material inside the feed barrel is injected into the injection mold through the feeding component. After the feeding is completed, the opening and closing component connects the middle part of the hot melt cylinder and the through cavity. Driven by the feeding component, the material inside the feed barrel forms a circulation, avoiding the temperature drop of the material when no liquid is injected, resulting in uneven temperature of the material liquid.

There are four opening and closing components 2, and the four opening and closing components 2 are all arranged on the side wall of the hot-melt barrel body 11. The four opening and closing components 2 are respectively arranged corresponding to the four through holes 14, and a feeding component 4 is arranged inside the feed barrel 1, and a storage component 3 is arranged on the outer wall of the feed barrel 1.

[0021] According to the above structure, when injection molding is carried out, the material inside the feed barrel 1 is injected into the injection mold through the feeding component 4. After the feeding is completed, the opening and closing component 2 connects the middle part of the hot melt cylinder 11 and the through cavity 13. Driven by the feeding component 4, the material inside the feed barrel 1 forms a circulation, avoiding the temperature of the material to drop when no liquid is injected, resulting in uneven temperature of the liquid.

[0022] like Figure 2 and 3 As shown, the opening and closing component 2 includes a plug 21 slidably connected to the inside of the through hole 14 and a shell 22 fixedly connected to the outer wall of the hot melt cylinder 11, one end of the shell 22 is fixedly connected to a hydraulic rod 23, one end of the hydraulic rod 23 is fixedly connected to one side of the plug 21, and one end of the plug 21 is symmetrically provided with air holes 24.

[0023] According to the above structure, when liquid is injected and fed, the hydraulic rod 23 extends the plug 21 to block the through hole 14, and the liquid is squeezed out from the conical head 12 into the injection mold. After the mold is filled, the hydraulic rod 23 shrinks the through hole 14 to open it, and the liquid in the middle of the hot melt cylinder 11 flows into the through cavity 13, and flows along the through cavity 13 to the tail of the hot melt cylinder 11, thereby forming a liquid circulation, so that the temperature of the liquid is uniform when no liquid is injected.

[0024] like Figure 2 and 3 As shown, the material storage component 3 includes a material storage barrel 31, the bottom end of the material storage barrel 31 is fixedly connected to a conical bucket 32, the bottom end of the conical bucket 32 ​​is fixedly connected to a material delivery pipe 33, the bottom end of the material delivery pipe 33 is fixedly connected to the side wall of the hot melt cylinder body 11, and a valve 34 is installed on the material delivery pipe 33.

[0025] According to the above structure, when in use, the polymer plastic particles are stored in the interior of the storage barrel 31 , and the plastic particles fall into the interior of the hot melt cylinder 11 through the conical bucket 32 ​​and the delivery pipe 33 .

[0027] According to the above structure, the screw rod 42 is driven to rotate by the reduction motor 41, and the screw rod 42 drives the plastic particles to be transmitted forward, and the plastic particles are heated and melted while being transmitted forward inside the hot melt cylinder 11.

[0028] The working principle of the utility model is as follows: when in use, the polymer plastic particles are stored in the interior of the storage barrel 31, and the plastic particles fall into the interior of the hot melt cylinder 11 through the conical bucket 32 ​​and the feed pipe 33. The screw rod 42 is driven to rotate by the reduction motor 41, and the screw rod 42 drives the plastic particles to be transmitted forward. While being transmitted forward inside the hot melt cylinder 11, they are heated and melted. When injection molding is performed, the hydraulic rod 23 extends the plug 21 to block the through hole 14, and the slurry is squeezed out from the conical head 12 into the injection mold. After the mold is filled, the hydraulic rod 23 contracts the through hole 14 to open it, and the slurry in the middle of the hot melt cylinder 11 flows into the through cavity 13, and flows along the through cavity 13 to the tail of the hot melt cylinder 11, thereby forming a slurry circulation, so that the slurry temperature is uniform when no injection is performed.
