Description

Technical Field

[0001] The present invention relates to the technical field of mold opening devices, and in particular to a mold opening device and a mold taking production line for product mold opening. Background Art

[0002] The existing document with announcement number CN108724445A discloses a demoulding and embryo removal production line for special-shaped gypsum molds, which includes a frame, a rotation positioning device, a lifting device, a clamping device, a demoulding device and an embryo removal device; the demoulding device is arranged on the slide rail of the frame, and the demoulding device includes a base, a demoulding cylinder, a supporting part, a tray part and a clamping part; the tray part is arranged between two supporting parts; the supporting part is connected to the demoulding cylinder; the two supporting parts and the tray part are used to support the special-shaped gypsum mold, and the clamping part is used to fix the special-shaped gypsum mold on the two supporting parts, and the supporting parts are driven by the demoulding cylinder to open and close each other horizontally along the direction perpendicular to the slide rail to separate or close the special-shaped gypsum mold.

[0003] The conventional mold opening structure under the existing technology has a small number of holes and insufficient production capacity. The post-molding process requires manual intervention, which wastes working hours, and the surface appearance of the product is usually inspected by manual naked eye by turning the product over for multiple times. According to industry experience, the conventional mold opening structure has a large proportion of defective phenomena: lack of meat, cracks, bubbles, etc., and cracks are mostly invisible defects. The workload is large during manual inspection, which will cause visual fatigue and cause missed inspections and false inspections. It cannot guarantee the inspection effect and inspection efficiency. Once it flows out, it is difficult for the client to find it, and different functions are lost after assembly and use. In addition, the flash treatment of the product is generally cleaned by a brush device. The existing cleaning device is generally driven by a transmission motor to drive the rotating shaft, and a sleeve is provided on the rotating shaft, and a cleaning brush is provided on the outer wall of the sleeve. When cleaning, debris and other impurities will adhere to the cleaning brush bristle body, which will not only affect its cleaning work, but also when rotating and cleaning, debris and other impurities may be thrown onto the product, which is easy to damage the product.
