Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding machine with a monitoring mechanism for injection materials. Background Technique

[0002] An injection molding machine is also known as an injection molding machine or an injection machine. It is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. It is divided into vertical, horizontal, and all-electric types.

[0003] However, for the existing injection molding machines, during injection molding, the injection materials are mostly monitored for the internal liquid level directly by mechanisms such as liquid level gauges. During the monitoring, the molding time and the quality after molding of the injection materials cannot be directly observed, so it still needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an injection molding machine with a monitoring mechanism for injection materials to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An injection molding machine with a monitoring mechanism for injection materials, including a processing panel, a top plate, and a second hydraulic rod,

[0006] A lower mold is installed inside the processing panel;

[0007] A first hydraulic rod and a molding shell are installed inside the top plate, and an upper mold is arranged on the output shaft of the first hydraulic rod;

[0008] A storage tank is installed on the top end surface of the top plate through a fixing frame;

[0009] A liquid level gauge and a feed pipe are embedded and fixed on the top end surface of the storage tank;

[0010] The storage tank is communicated with the upper mold through a discharge pipe, and a valve is installed on the discharge pipe through a flange;

[0011] A top plate is arranged on the output shaft of the second hydraulic rod, and the top plate is sleeved inside the molding shell;

[0012] A connecting pipe is embedded and fixed on the rear end surface of the storage tank.

[0013] Preferably, a second support frame is welded on the bottom end surface of the top plate, and the bottom end surface of the second support frame is welded on the processing panel. The top plate can be installed and fixed on the processing panel through the second support frame.

[0014] Preferably, a first support frame is welded on the bottom end surface of the processing panel, and a bearing base is welded on the bottom end surface of the first support frame. The processing panel can be supported and installed through the first support frame and the bearing base.

[0015] Preferably, a guide rod is installed on the top surface of the upper mold, and the guide rod is sleeved in the top plate. When the upper mold is pushed by the hydraulic rod, the two ends are sleeved in the top plate through the guide rod for limiting and guiding.

[0016] Preferably, a driving mechanism is installed on the top surface of the storage tank, and a stirring rod is arranged on the output shaft of the driving mechanism via a rotating shaft. When the driving mechanism is turned on, the driving mechanism can drive the stirring rod to rotate via the rotating shaft.

[0017] Preferably, a mounting frame is installed on the hydraulic rod 2, and the top end surface of the mounting frame is welded to the bottom end surface of the top plate. The hydraulic rod 2 can be connected to the top plate through the mounting frame.

[0018] Preferably, one end of the connecting pipe facing away from the storage tank is embedded and fixed in the molding shell, and a valve is installed on the connecting pipe through a flange. When the valve on the connecting pipe is opened, the injection plastic in the storage tank can be discharged into the molding shell through the connecting pipe.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] 1. The utility model sets an upper mold and a lower mold. When personnel perform injection molding operations, they can open the valve on the discharge pipe to discharge the injection plastic in the storage tank smoothly into the upper mold, and the discharge pipe can be expanded by using a telescopic pipe to cooperate with the movement of the upper mold. In addition, during the process of discharging the injection plastic, personnel can also start the hydraulic rod 1 to push the upper mold and the lower mold to close tightly. At the moment of closing, the injection plastic quickly enters the upper mold and the lower mold, and the injection molding process begins. At the same time, the injection plastic liquid level in the storage tank will be monitored in real time by a liquid level gauge. When the injection plastic needs to be stirred to prevent it from settling, the personnel only need to turn on the drive mechanism, and the drive mechanism will drive the stirring rod to rotate at a uniform speed through the rotating shaft, so that the stirring rod effectively drives the injection plastic to stir. In this way, it can not only avoid the precipitation of the injection plastic, but also meet the needs of injection molding, and at the same time, it can also achieve accurate monitoring of the liquid level.

[0021] 2. By setting up the forming shell in the present utility model, before the staff perform the injection molding operation, in order to closely monitor the injection molding material, they can open the valve on the connecting pipe. In this way, the injection molding material in the storage tank can smoothly drain into the forming shell along the connecting pipe. During the drainage process, the staff can directly observe the quality status of the injection molding material inside the forming shell. Moreover, the injection molding material can also be processed into a formed product inside the forming shell. After the forming is completed, the staff can activate the second hydraulic rod to push the ejector plate upward. As the ejector plate moves upward, it can eject the injection molding material formed inside the forming shell. After ejection, these injection molding materials can be used to observe the forming situation and the quality after forming, enabling the staff to conduct intuitive and comprehensive monitoring of the injection molding material.
