Disclosed is a full-automatic method for manufacturing plant-fiber molding products and margin trimming and molding machines. The invention achieves functions: wet semi-finished product forming, hot press mold solidifying, and automatic margin trimming. The full-automatic method is as below: pulps are continuously made into wet semi-finished products by means of a suck-filter forming device, which is alternatively fed into hot-press molds of the left hot-press mold solidifying device and the right hot-press mold solidifying device after being heated to a certain temperature in hot-press molds for hot-press drying and solidifying. The dried and solidified products fall into the left positioning collecting tray and the right positioning collecting tray respectively from the left hot-press top mold and the right hot-press top mold, and are positioned therein. The full-automatic plant-fiber molding, mold solidifying and margin trimming machine includes a forming and solidifying device, a transfer device and a margin trimming device.

A multi-cavity mould (1) comprising:—an upper tool (11) and a lower tool (12) arranged in a cooperating manner; characterized in that the upper tool (11) comprises a knife pressure box (13) comprising:—a horizontal top plate (131);—first and second end plates (132) and first and second side plates (133) extending orthogonally downwardly from a lower surface of the plate (131); the plates (132, 133) are connected such that the plate (131) and the plates (132, 133) form a downwardly open rectangular parallelepiped enclosure; the plates (132, 133) are made from tool steel with a thickness (t) from 6.35-10 mm and a cutting surface (130) defined along an orthogonally downwardly projecting end of plates (132, 133) wherein—the surface (130) has a substantially V-shaped profile comprising a micro flat face (M) with a width from 0.02-0.1 mm and is positioned such that when the pressure box (13) is pressed against the sheet (3), the surface (130) partially penetrates the sheet (3) in order to form a seal around the pressure box (13) by pressing a zone of the sheet (3) which was partially trimmed and situated inside the enclosure against the surface (130).

A multi-cavity mould (1) for a thermoforming machine used in the process of high-volume, continuous thermoforming of a plurality of thin-gauge plastic products (2) from a preheated thin-gauge thermoplastic sheet (3) comprising an upper tool (11) and a lower tool (12) arranged in a cooperating manner; the lower tool (12) comprising a plurality of cavities (8) in which cavity moulds (8) are placed and a plurality of base plates (91) from which a plurality of supporting blocks (92) extend perpendicularly over a predetermined total height (a), situated between adjacent cavities (8), each of said supporting block (92) has a stepped profile comprising three substantially rectangular shaped zones (92a, 92b, 92c) and a fourth substantially isosceles trapezoid shaped zone (92d) in a vertical cross section, having a common symmetry axis.

A thermoforming trim press has one or more connecting arms for driving a movable platen, each arm having a pivotal connection between two adjacent sections of each connecting arm which is normally locked during normal press operation whereby the movable platen is able to move further back from a normal retracted position to increase the available clearance when changing or maintaining tools mounted on the movable platen. The pivoting ability of the connecting arm sections also simplifies adjusting the stroke of the press. A counterweight may be driven by the crank pins to match the press stroke adjustments and to thereby correspond the movement of the counterweight to the movement of the movable platen.
