Description

TECHNICAL FIELD

[0001] The application relates to the technical field of injection molding equipment, and particularly relates to an embedded iron part injection molding device and a method thereof. BACKGROUND

[0002] The injection molding device is a key equipment for processing plastic raw materials into plastic products. The injection molding device cooperates with a series of complex mechanical, hydraulic and electrical control systems to heat plastic particles or powder into plastic, and then injects the plastic into a mold cavity under high pressure, so that the plastic is solidified after cooling to obtain a plastic product. With the development of injection molding technology, iron parts are embedded in injection molded parts, and the embedded iron part injection molding device generally needs to place the iron parts in the mold, and after injection molding, the injection material will wrap the iron parts into a shape. Such products are widely used in the manufacturing field of automobile parts.

[0003] The embedded iron part injection molding device is a cooperation between the existing injection molding equipment and the mechanical arm. The iron part is embedded into the injection molding mold by the mechanical arm, and then the product is injection molded by the injection molding equipment. Finally, the mechanical arm is used to take and place the molded product.

[0004] In the prior art, a Chinese patent with the authorization publication number CN113290802B discloses an injection molding equipment capable of automatically discharging and a method thereof, which comprises a machine body. One side of the top of the machine body is provided with an injection molding mechanism, and the other side of the top of the machine body is provided with an injection molding bin.

[0005] Although the technical scheme in the above patent document realizes automatic discharging of the molded product, the following defects still exist in the use process: although the molded product is directly contacted with the liquid in the lower receiving groove after demolding, which can realize rapid cooling of the product, the heat stress in the product may cause deformation or cracking of the product, thereby affecting the qualified rate of the product; some impurities are attached to the molded product, and part of the impurities will fall into the liquid when the molded product is cooled by contacting with the liquid. The filter screen plate can only realize separation of the molded product and the liquid, and cannot filter the impurities mixed in the liquid, so that the content of the impurities in the liquid will continuously increase during the subsequent discharging process of the molded product, thereby there is a risk of polluting the subsequent products.
