Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to an integrated injection molding machine for composite materials. Background Technology

[0002] In the early days of injection molding technology, machines primarily relied on manual operation to melt and mold plastics, resulting in low efficiency and low production quality. With the rapid development of the plastics industry, injection molding technology has significantly improved. The performance of injection molding machines has continuously improved, enabling more precise control of temperature, pressure, and injection speed. Simultaneously, the variety of plastic materials has increased, expanding the possibilities for the application of injection molding technology.

[0003] Composite materials are widely used in the aerospace field due to their lightweight, high strength, and high temperature resistance. In order to improve the performance of single materials, people have begun to try to combine materials with different properties. Composite materials are usually pre-mixed manually and then added to the feed hopper of the injection molding machine, which increases the processing time and labor costs of the product. Utility Model Content

[0004] The purpose of this utility model is to provide a composite material injection molding integrated machine that can mix multiple materials in the injection molding equipment, reducing the steps of manual pre-mixing and adding the mixed materials into the feed hopper of the injection molding equipment, shortening the product processing time and reducing labor costs.

[0005] To achieve the above objectives, a composite material injection molding integrated machine is provided, comprising an injection molding machine body, wherein the injection molding machine body includes an injection cylinder, and a feeding mechanism is fixedly connected to the upper end of the injection cylinder, and the bottom of the feeding mechanism is connected to the injection cylinder. A valve plate is provided on one side of the feeding mechanism, and the valve plate extends into the feeding mechanism and is slidably connected to the feeding mechanism. The feeding mechanism consists of an upper cover, a mixing hopper, a feeding hopper, a motor, and a stirring screw. The mixing hopper is fixedly connected to the upper end of the injection cylinder, and the bottom of the mixing hopper is connected to the injection cylinder. The valve plate extends into the mixing hopper from the end furthest from the slider and is slidably connected to the mixing hopper. The upper cover is located at the top of the mixing hopper and connected to the mixing hopper flange. The feed hopper is welded to the top of the upper cover, and its bottom extends through the upper end. The motor is fixedly connected to the middle of the upper end of the upper cover, and its output shaft extends downward through the upper cover. The motor's output shaft is rotatably connected to the upper cover via a bearing. The stirring screw is located at the middle of the lower end of the upper cover, and the motor's output shaft is fixedly connected to the stirring screw via a coupling. The valve plate is located at the bottom of the stirring screw. This system enables the mixing of multiple materials in injection molding equipment, reducing the steps of manual pre-mixing and adding the mixed material to the feed hopper of the injection molding equipment, shortening product processing time, and reducing labor costs.

[0006] According to the composite material injection molding integrated machine, the upper opening of the feed hopper is provided with a cover plate, and a hinge is installed on one side of the cover plate and the feed hopper, and the cover plate and the feed hopper are rotatably connected by the hinge. The cover plate seals the upper end of the feed hopper to prevent dust generated during material mixing from drifting into the external environment.

[0007] According to the composite material injection molding machine, a handle is welded to the upper end of the cover plate, and the handle is located on the side of the cover plate away from the hinge. The handle facilitates the operator in lifting the cover plate.

[0008] According to the composite material injection molding integrated machine, a guide rail is fixedly connected to the upper end of the injection cylinder. A U-shaped slider is fitted onto the surface of the guide rail, and the inner wall of the slider is slidably connected to the guide rail. The end of the slider facing the feeding mechanism is fixedly connected to a valve plate. The slider and the guide rail work together to drive the valve plate to move linearly, improving the efficiency of the valve plate in controlling the bottom switch of the mixing hopper.

[0009] According to the composite material injection molding integrated machine, a locking bolt is provided on one side of the slider, and one end of the locking bolt passes through the slider and is threadedly connected to the slider. The end of the locking bolt passing through the slider contacts the surface of the guide rail. The locking bolt is used to fix the slider after the valve plate has moved, thereby preventing the valve plate from moving.

[0010] According to the aforementioned composite material injection molding machine, the surface of the mixing hopper is provided with a transparent observation window that extends through the mixing hopper. The observation window facilitates the operator's observation of the mixing effect of the materials in the mixing hopper, preventing incomplete mixing of materials before they enter the injection molding equipment.

[0011] The above-mentioned solution has the following beneficial effects: The valve plate prevents materials from entering the injection cylinder before they are fully mixed. The motor drives the stirring screw to mix the materials, shortening the product processing time and reducing labor costs.
