Description

Technical Field

[0001] This application relates to the field of injection molding machine technology, and more specifically, to an intelligent temperature-controlled drying device for injection molding machines. Background Technology

[0002] Injection molding is a method of industrial product manufacturing. Products are typically produced using rubber injection molding and plastic injection molding. An injection molding machine is the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Injection molding is achieved through an injection molding machine and molds. In the injection molding process, if granular or powdered raw materials are not sufficiently dried, it can cause bubbles, silver streaks, flow marks, and other defects that affect product quality.

[0003] A search revealed Chinese patent application CN207669663U, which discloses an intelligent injection molding material feeding and drying device. This device features a drying chamber outlet located at the bottom center of the drying chamber, with an electrically controlled valve at the outlet. The controller is electrically connected to a suction device, heater, air distribution device, temperature and humidity sensor, touch screen display, and the electrically controlled valve. In application, this device automates the material feeding and drying process of the injection molding machine, effectively reducing heat loss during drying. It offers advantages such as simple operation, high efficiency, and energy saving. However, the aforementioned intelligent injection molding material feeding and drying device has the following shortcomings: existing material drying devices do not allow for convenient feeding and discharging, leading to inconvenience during use. Furthermore, the drying position cannot be easily adjusted, resulting in a fixed drying location and uneven material drying.

[0004] In view of this, we propose an intelligent temperature-controlled drying device for injection molding machines. Utility Model Content

[0005] Technical problems to be solved

[0006] The purpose of this application is to provide an intelligent temperature-controlled drying device for injection molding machines, which solves the problems of inconvenient material feeding and discharging, resulting in inconvenience during use, and the inability to easily adjust the drying position, leading to a fixed drying position and uneven material drying.

[0007] Technical solution

[0008] This application provides an intelligent temperature-controlled drying device for injection molding machines, including: a drying chamber, a collection box, and an air inlet pipe. A top plate is fixedly installed on the top of the drying chamber, and a collection box is fixedly installed inside the drying chamber. An inlet extending into the collection box is provided on the top plate. A bottom plate corresponding to the bottom of the collection box is movably installed inside the drying chamber. The bottom of the bottom plate is movably connected to the inner side of the drying chamber via a first telescopic rod. A connecting frame is fixedly installed on the bottom of the top plate, and an ejector plate is movably installed on the inner side of the connecting frame. An air inlet pipe extending out of the top plate is fixedly installed on the connecting frame.

[0009] Preferably, an installation ring is fixedly installed on the outside of the drying box, and a support column is fixedly installed on the outside of the installation ring.

[0010] Preferably, a material guide port is fixedly installed inside the drying box, the drying box is movably installed with the bottom plate via a rotating seat, and both ends of the first telescopic rod are movably installed with the bottom plate and the drying box via movable seats.

[0011] Preferably, the spray plate and the connecting frame are movably installed via a second telescopic rod, and a connecting block that cooperates with the second telescopic rod is fixedly installed on the outer side of the spray plate.

[0012] Preferably, the inner side of the connecting frame is provided with a movable groove for the connecting block to move, and the outer side of the drying box is fixedly installed with a protective cover corresponding to the second telescopic rod.

[0013] Preferably, the outer side of the air inlet pipe is connected to an outer pipe, and the outer pipe is connected to the ejection disc through a corrugated pipe. Beneficial effects

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0015] This application, through the configuration of an external pipe, a second telescopic rod, a spray disc, and the cooperation between the external pipe and the corrugated pipe, allows hot air to be filled into the collection box through the air inlet pipe, and to be injected into and discharged into the spray disc through the external pipe and the corrugated pipe. The spray disc is used to dry the material filled inside the collection box. At the same time, the extension and retraction of the second telescopic rod can drive the spray disc to move up and down inside the connecting frame, which can make the material inside the collection box dry more evenly.

[0016] This application utilizes a base plate, a first telescopic rod, a movable seat, and a rotating seat in a coordinated manner. The telescopic action of the first telescopic rod causes the base plate to flip, allowing it to rotate around the rotating seat. This enables the base plate to open and close with the bottom of the collection box, making unloading and filling processes more convenient and increasing work efficiency.

An inlet 104 extending into the collection box 2 is provided on the top plate 103. A bottom plate 202 corresponding to the bottom of the collection box 2 is movably installed inside the drying chamber 1. The bottom of the bottom plate 202 is movably connected to the inner side of the drying chamber 1 via a first telescopic rod 203. A connecting frame 301 is fixedly installed on the bottom of the top plate 103, and an ejector plate 304 is movably installed on the inner side of the connecting frame 301.

The spray plate 304 is used to dry the material filled in the collection box 2. At the same time, the extension and retraction of the second telescopic rod 306 can drive the spray plate 304 to move up and down inside the connecting frame 301, so that the material inside the collection box 2 can be dried.

[0026] In summary, the intelligent temperature-controlled drying device for injection molding machines disclosed in this application, when in use, can fill the interior with hot air through the air inlet pipe 3, and inject and discharge into the interior of the spray plate 304 through the outer pipe 302 and the corrugated pipe 303. The spray plate 304 is used to dry the material filled in the collection box 2. At the same time, the extension and retraction of the second telescopic rod 306 can drive the spray plate 304 to move up and down inside the connecting frame 301, which can make the material in the collection box 2 dry more evenly. The extension and retraction of the first telescopic rod 203 can drive the bottom plate 202 to flip, so that the bottom plate 202 can rotate around the rotating seat 201, thereby enabling the bottom plate 202 and the bottom of the collection box 2 to open and close, making the unloading and filling process more convenient, thereby increasing work efficiency.
