Description

Technical Field

[0001] This utility model relates to the field of injection mold cleaning technology, and more specifically, to a device for cleaning residual material in injection mold runners. Background Technology

[0002] Injection mold runner residue cleaning refers to the process where, due to various reasons, plastic material remains in the mold's runner system during injection molding, forming cold or solidified residue. This residue can affect the quality of subsequent products and production efficiency, thus requiring timely cleaning. Generally, a scraper is used to repeatedly scrape the inner wall of the inlet, and then the scraped debris is blown away. However, due to the small diameter of the inlet and its bends, it is very difficult to clean the bends thoroughly, and residues will still remain.

[0003] A search revealed that Chinese patent CN218985505U discloses a device for cleaning residual material in injection mold runners. By using a cleaning box, an air guide pipe, and other cleaning components, high-pressure gas can be used to clean the runners of the injection mold, and then the debris inside the injection mold can be extracted and removed, thus achieving the effect of cleaning the runners.

[0004] When the above-mentioned cleaning device is in use, the air pump starts to work and uses the second cleaning head to extract and clean the residue inside the injection mold body. However, it is inconvenient to filter the residue. The residue enters the air pump through the second air guide pipe, and the residue is easy to clog the air pump, thus affecting the service life of the air pump. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for cleaning residual material in injection molds, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for residual material in injection mold runners, comprising a cleaning box, a first air pipe, and a second air pipe, wherein the bottom end of the first air pipe is fixedly connected to the cleaning box, the second air pipe is located on one side of the cleaning box, and a cleaning assembly is provided on the other side of the cleaning box. The cleaning assembly includes a third air pipe, a hose, and a nozzle. One end of the third air pipe is movably connected to the cleaning box via a bearing, and both ends of the hose are fixedly connected to the third air pipe and the nozzle, respectively. A storage cylinder is fixedly connected inside the cleaning box, and a filter assembly is provided on the second air pipe. The filter assembly includes an external threaded sleeve and a filter screen. The external threaded sleeve is fixedly sleeved on the second air pipe and is threadedly connected to one side of the cleaning box. One side of the filter screen is fixedly connected to the external threaded sleeve.

[0007] Furthermore, a sealing gasket is adhered to the external threaded sleeve, and the outer side of the sealing gasket is in contact with the cleaning box.

[0008] It can be seen that the above technical solution aims to improve the sealing performance between the external threaded sleeve and the cleaning box.

[0009] Furthermore, valves are fixedly installed on both the first and second air pipes, and a connecting plate is fixedly connected to one end of both the first and second air pipes.

[0010] Furthermore, a guide hopper is fixedly connected inside the storage cylinder.

[0011] It can be seen that the above technical solution is designed to facilitate the guidance of residual materials.

[0012] Furthermore, a fixing plate is fixedly sleeved on the third air pipe, a hydraulic cylinder is fixedly connected to one side of the fixing plate, a side plate is fixedly connected to one end of the hydraulic cylinder, and the top of the side plate is fixedly connected to the nozzle.

[0013] It can be seen that the above technical solution is designed to facilitate the adjustment of the nozzle's position within the injection channel.

[0014] Furthermore, a first gear is fixedly sleeved on the third air pipe, a second gear meshes with the bottom of the first gear, a rotating shaft is fixedly connected to one side of the second gear, a stepper motor is fixedly connected to one end of the rotating shaft, and the stepper motor is fixedly installed on the other side of the cleaning box.

[0015] It can be seen that the above technical solution is designed to facilitate the adjustment of the nozzle position.

[0016] Furthermore, fixing plates are fixedly connected to both the front and rear sides of the cleaning box.

[0017] As can be seen, in the above technical solution, bolts are used to facilitate the fixing of the cleaning box.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. This utility model uses a nozzle to clean the residue in the injection channel. The valve on the first air pipe is closed and the valve on the second air pipe is opened. The air pump works so that the residue in the injection channel can enter the cleaning box through the nozzle. The filter screen filters the residue. The second air pipe is rotated so that the external threaded sleeve is away from the cleaning box, thereby releasing the fixation between the second air pipe and the cleaning box and cleaning the residue in the storage cylinder. The operation is simple, it is convenient to filter the residue, and it effectively improves the service life of the air pump.

[0020] 2. This utility model uses the extension of the piston rod on the hydraulic cylinder to drive the side plate to move horizontally, thereby driving the nozzle to move horizontally. The position of the nozzle in the injection channel can be adjusted as needed. The stepper motor is started, and the stepper motor drives the rotating shaft and the second gear to rotate, thereby driving the first gear and the third air pipe to rotate, which in turn drives the nozzle to rotate. The position of the nozzle can be adjusted as needed to facilitate a thorough cleaning of the injection channel, resulting in good performance. Attached Figure Description
