Abstract

The invention provides a device for injection molding of long glass fibers. The device comprises a feeding system, an injection table mechanism and a processor, wherein the feeding system is configured to be used for providing and conveying materials, and the materials comprise long glass fiber bundles; the injection table mechanism is configured to be used for melting and injection molding of thematerials; and the processor is configured to receive and store a material formula input by a user, control the feeding system to convey the long glass fiber bundles with the metering target value tothe injection table mechanism according to the metering target value and control the injection table mechanism to melt the materials, wherein the material formula comprises the metering target valueof each material.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a device for injection molding of long glass fibers. Background technique [0002] As products have higher requirements for materials, polymer materials have been paid more and more attention in the process of product manufacturing. It is a common practice to use long glass fibers (long glass fibers) as additives for plastic modification to strengthen the structure. Long glass fibers are widely used due to their good mechanical properties and recyclability; especially in application scenarios that require lightweight products, such as automobiles, electrical appliances, ships, etc. [0003] However, fiber reinforced polymers in the prior art usually require several materials to be prepared by mixing them in proportion. The most commonly used method is the so-called "two-step method" in the industry. The first step needs to mix the materials Made into granules, which i...
