[0002] The air flow meter is a sensor used to measure the air flow entering the engine.

The ECU accurately calculates the amount of fuel injection based on this signal to ensure that the engine can obtain the ideal air-fuel ratio under various operating conditions, thereby achieving efficient combustion, reducing emissions and ensuring power performance. Common types of air flow meters include vane type, Karman vortex type, hot wire type and hot film type. The performance and accuracy of the air flow meter are crucial to the normal operation and emission control of the engine. If the air flow meter fails, it may cause problems such as insufficient engine power, increased fuel consumption, and excessive emissions.

[0018] The present invention provides an injection molding device for processing a plastic shell of an air flow meter. It has the following beneficial effects:

[0019] 1. The injection molding equipment for processing the plastic shell of the air flow meter is designed with a composite mechanism. The plastic raw material enters the composite shell from the feed port, and the motor rotates the rotating shaft. The rotation of the rotating shaft rotates the rotating frame and the rotating plate, thereby expanding the stirring range and improving the mixing effect, thereby ensuring the stability and consistency of the quality of the injection molded products, and cutting the plastic raw material through the cutting block to achieve the effect of dividing larger raw materials, so that the plastic raw material particles are uniform.

[0020] 2. The injection molding equipment for processing the plastic shell of the air flow meter is designed with a rotating mechanism. After the plastic raw materials are cut, the particles are attached. The rotating shaft drives the bevel plate to scrape the inner wall of the equipment, thereby preventing the raw materials from sticking, avoiding resource waste and residue, and improving work efficiency. Secondly, by opening bevel grooves, the chip removal effect is increased through grooving, preventing the raw materials from being adsorbed on the equipment and affecting the rotation and cleaning effect. Secondly, through the bevel design, the output point of the raw materials is guided to move toward the center of the equipment to improve the uniformity of the mixing. Secondly, the spring bar plays a role of shock absorption and buffering, reducing the collision with the raw materials attached to the inner wall, protecting the equipment and extending the service life of the equipment.

[0021] 3. The injection molding equipment for processing the plastic shell of the air flow meter is designed with a friction mechanism. After the raw materials enter the interior of the equipment, some of them are precipitated. Therefore, the raw materials are rubbed by the grinding column to uniform the particle size, increase the melting speed, and improve the stability of the processing. The flow rate of the raw materials and the effect of filling the mold are more stable, thereby reducing fluctuations and uncertainties in the processing process. Secondly, the covering shell plays a role in limiting the movement when the grinding column rubs, preventing the raw materials from scattering, and playing a role in concentrating the raw materials.

[0022] 4. The injection molding equipment for processing the plastic shell of the air flow meter, through the output mechanism design, controls the closing size of the closing block through the electric push rod, so as to control the descending speed of the raw material. Proper control of the descending speed of the raw material helps to ensure that the plastic is evenly and smoothly filled in the mold cavity, avoiding defects such as short shots, flash, bubbles, etc., so as to obtain high-quality injection molded products. By opening strip grooves and using inclined design, the flow effect of the raw material is increased, material residue is avoided, and resource costs are reduced.

[0023] 5. The injection molding equipment for processing the plastic shell of the air flow meter is designed through a processing mechanism. The raw materials enter the processing shell from the output mechanism, and the feed rod is driven to rotate by a driving machine. The feed rod is connected to a spiral plate to transport the material to one side of the injection head, and then the internal raw materials are melted by a heater. The design of multiple heaters increases the heating distance, improves the melting efficiency, and increases the melting effect. By melting the raw materials uniformly, the overall heating of the raw materials is ensured, which helps to improve the melting quality and efficiency. The spiral design of the spiral plate increases the mixing effect of the plastic raw materials, improves the injection molding quality, reduces the internal gas of the plastic raw materials, and prevents bubbles from injection molding.
