A kind of integrated mould and method for punching and trimming of pulp moulded products

Abstract

The invention discloses an integrated mould and method for concave and trimming of pulp moulded products, and relates to the technical field of pulp moulded product processing. The mold includes a mold body; the mold body includes a guide sleeve bottom plate; the top surface of the guide sleeve bottom plate is fixedly connected to a guide rod; the peripheral side surface of the guide rod is slidably connected with an upper mold seat; The bottom surface of the knife plate is fixedly connected with the knife frame plate and the fixed seat respectively through the connecting piece; the bottom surface of the knife frame plate is fixedly connected with the cutting die; the bottom surface of the fixed seat is fixedly connected with the concave punch through the connecting piece; the bottom surface of the concave punch is fixedly installed with a Hit the punch. The method of the invention integrates the concave and edge trimming operations on the pulp molded product, so as to avoid the occurrence of fluffing, deformation, cracking and folds, as well as the phenomenon that the concave size varies in depth and the edge trimming knife cannot cut through.

Description

technical field [0001] The invention belongs to the technical field of pulp molding product processing, and in particular relates to a high-end pulp molding product integrated die and method for concave and trimming. Background technique [0002] Paper mold industry paper trays generally use wood pulp and sugarcane pulp as raw materials, such as egg trays, lunch boxes, etc., which are of low value and sufficient supply; while high-end pulp molding products are often packaged for some high-end electronic products, mechanical parts, handicrafts, Cosmetics and high-end luxury goods, such as laptops, mobile phones, audio medical facilities, electronic cigarettes, ipads, high-end watches, high-end lamps and so on. Due to the high value of the packaged object itself, the inner packaging cost acceptable to customers is also relatively high. [0003] The production process of high-end pulp molding products is as follows: pulp raw materials or plant fibers are first filtered and for...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a high-end pulp molded product integrated die with concave and edge cutting. Through the design of the concave punch, concave punch and cutting die, the problem of the impact of the existing pulp molded product processing equipment is solved. The theoretical value of the design of the concave punch is far from the size and appearance requirements of the actual punching effect. The cycle marks on the product are roughened, deformed, cracked, and wrinkled, and the size of the concave is different. Do not wear and other issues
