Description

Technical Field

[0001] The invention relates to an injection molding machine device, in particular to a device for assisting the demoulding of injection-molded products of the injection molding machine. Background Art

[0002] Injection molding is a processing method that feeds molten material into a steel ingot mold to form parts of a certain shape. Demolding refers to a series of operations to remove the object from the steel ingot mold after injection molding, which is an important step in the injection molding process.

[0003] The Chinese patent document with the existing authorization announcement number CN218948378U discloses a device for assisting the demoulding of injection molding products of an injection molding machine, and its scheme includes a driving motor, a ball screw is installed at the output end of the driving motor, a screw nut seat is provided on the outer side of the ball screw, a moving plate is provided on one side of the screw nut seat, a cooling plate is installed on one side of the screw nut seat, a lower mold is installed on one side of the cooling plate, a cooling pipe is installed inside the cooling plate, a connecting pipe is provided on one side of the cooling pipe, and a water pump is connected to the other end of the connecting pipe. Its scheme starts the water pump to send the coolant through the connecting pipe to the cooling pipe of the cooling plate. The coolant can take away the heat in the lower mold and help the material in the lower mold to dissipate heat quickly, thereby improving the demoulding efficiency. After that, the coolant will enter the heat dissipation pipe, and the heat inside it will be dissipated by the heat dissipation fan, thereby forming a cooling cycle. In the injection molding process, after the movable mold and the fixed mold are separated, some products are formed in the mold cavity. At this time, the product inside the mold cavity needs to be cooled accordingly. Generally, a corresponding water cooling structure or air cooling structure is set in the fixed mold; then some products are formed and attached to the mold core, such as the processing and production of plastic benches. The finished product is adhered to the mold core on the fixed mold. For the removal of the product, the movable mold is generally separated directly, and the product is exposed to the outside world for natural cooling. After a certain period of time, the staff removes the product by hand. This process lacks a suitable product demolding mechanism to assist its demolding work, and needs to be improved and optimized.

At the same time, the four groups of demoulding support components are simultaneously supported on the four bottom feet of the plastic bench. When the demoulding work is performed, the force on the product will be evenly distributed. When the demoulding work is performed, the problem of product deformation due to local force can be well avoided. The supporting hydraulic cylinder 701 pushes up to drive the product to move upward. At the same time, while moving upward, the demoulding auxiliary component connected to the demoulding top column 703 is further Cooling: During the process of the demoulding top column 703 being pushed up, the air outlet body 802 arranged on the demoulding top column 703 will be exposed, and the cooling gas will be transported through the cooling air delivery pipe 804. The cooling gas will gather in the hollow cavity 801 and then be ejected from the air outlet body 802. The ejected cooling air will pass between the molding core 23 and the product, and can perform an auxiliary cooling work for the molding core 23 and the product. On the one hand, it is convenient for the rapid cooling and demolding of the product. On the other hand, it improves the cooling speed of the product and the molding core 23, which is helpful for the next injection molding process and avoids the product from being scalded.
