Description

Technical Field

[0001] The utility model relates to the field of injection molding, in particular to a mixer for injection molding. 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 ejected and fill the mold cavity. In order to provide production quality during the use of the injection molding machine, a mixer is often required as an intermediary between injection molding and mixing. The existing mixer is more troublesome during use and has a high installation cost. In the mixing process, uneven material mixing is prone to occur, resulting in uneven texture of the injection molded model during injection molding by the injection molding machine, which is easy to affect the quality of the product. For this reason, we propose an injection molding mixer to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a mixer for injection molding to solve the problems raised in the above background technology.

[0006] In a further embodiment, the upper surface of the mixing tank is fixedly connected to a connecting bin, a hand-crank switch is installed inside the connecting bin, and the upper surface of the connecting bin is fixedly connected to a feeding bin.

[0007] In a further embodiment, the bottom end of the mixing tank is fixedly connected to a discharge valve, the upper surface of the mixing tank is fixedly connected to a temperature sensor, and the upper surface of the bottom plate is fixedly connected to a cabinet.

[0008] In a further embodiment, a console is fixedly connected to the upper surface of the chassis, and a data display screen is fixedly connected to the outer surface of the console.

[0009] In a further embodiment, the inner side walls of the chassis are respectively fixedly connected with a temperature controller, a heating controller and a motor controller.

[0010] In a further embodiment, a warning sign is fixedly connected to the left side of the chassis, and heat dissipation holes are provided on the front and back of the chassis.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The device can stir and mix the mixed materials more evenly during mixing through the motor, rotating rod, stirring rod and spiral blades. The mixed materials can be better heated by the metal heating rod to make them more fluid during stirring. The stirring rod and spiral blades can better squeeze out the air in the materials to avoid bubbles in the subsequent injection molding of the materials. Through the connecting bin and the hand-crank switch, the materials can be poured into the feeding bin first, and then the materials can be gradually put into the mixing tank through the hand-crank switch, which effectively avoids the reduction of the temperature and air pressure inside the mixing tank. The temperature sensor and the data display screen can better observe the monitoring data inside the mixing tank in real time. BRIEF DESCRIPTION OF THE DRAWINGS
