Abstract
The invention discloses a preparation method of a composite wiper plastic part. The preparation method comprises the following steps: (1) drying materials before processing, and testing whether the materials are dried completely or not by an air injection method; (2) selecting an injection system with more temperature control sections and little self-friction heating during plasticization, wherein the actual weight of a product is not less than 2/3 of the injection amount of a machine; (3) molding a blank by an integral hot runner mold, wherein a heat insulation plate is arranged between the mold and a mold plate of an injection molding machine; (4) measuring by the air injection method at melting temperature; and (5) completing the injection of the materials within 3-5s. A hot runner spray nozzle is an open type hot spray nozzle. The preparation method disclosed by the invention has the characteristics of simple process and good product quality.
Description
Technical field
The invention belongs to technical field of automobile, relate to the preparation method of compound rain brush working of plastics.
Background technology
Rain brush is used to strike off and is attached to sleet water on windshield or mud, to maintain the good sight line of driver, and then improve the safety of person for driving a car's driving, and rain brush is to drive running by driving brush arm.There is the principle of bone rain brush to be by the some strong points on skeleton, rain shaving blade is pressed on glass, make the pressure of each strong point on rain shaving blade average.Existing rain brush is usually understood additional transition assembly and is coordinated well various multi-form driving brush arm, forms composite wind shield wiper.But after composite wind shield wiper forming plastic pieces, there is certain difference with predetermined quality standard (test stone), and lower procedure calls can not be met, plastic parts defect that Here it is, namely what is often called quality problem, study these defect producing cause, and be down to minimum level.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of preparation method of compound rain brush working of plastics, has technique simple, the feature of good product quality.
Object of the present invention carrys out specific implementation by the following technical programs:
A preparation method for compound rain brush working of plastics, comprises the steps, (1) carries out drying to material before processing, penetrates method experimental material whether bone dry with sky; (2) select that temperature control section is more, plasticizing time self-friction heat-dissipating few injecting systems, goods actual weight is more than or equal to 2/3 of machine injection amount; (3) idiosome monoblock type hot runner mould is shaping, has thermal insulation board between mould and injection moulding machine template; (4) melt adhesive temperature, uses the sky method of penetrating to measure, and (5) shoot material and to complete within 3-5 second.
Further, in (3) step, hot-runner nozzle is open hot nozzle.
Compared with prior art, the present invention has following beneficial effect:
Working of plastics Shooting Technique of the present invention is simple, good product quality.And have good anti-wear, resistance to elevated temperatures, the weather of global zones of different can be adapted to.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
The preparation method of a kind of compound rain brush of embodiment working of plastics, comprise the steps, (1) carries out drying to material before processing, penetrates method experimental material whether bone dry with sky; (2) select that temperature control section is more, plasticizing time self-friction heat-dissipating few injecting systems, goods actual weight is more than or equal to 2/3 of machine injection amount; (3) idiosome monoblock type hot runner mould is shaping, has thermal insulation board between mould and injection moulding machine template; (4) melt adhesive temperature, uses the sky method of penetrating to measure, and (5) shoot material and to complete within 3-5 second.
Further, in (3) step, hot-runner nozzle is open hot nozzle.
Last it is noted that the foregoing is only explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
