Abstract

uma máquina de moldagem sem caixa de molde 1 que possui: uma caixa de molde superior (15) e uma caixa de molde inferior (17), capazes de prender uma placa de emparelhamento; uma unidade de acionamento (37), a qual move a caixa de molde inferior na direção vertical; uma estrutura de enchimento inferior (41), capaz de se conectar com a caixa de molde inferior; uma placa superior (25), capaz de entrar e ser retirada da caixa de molde superior; uma placa inferior (40), capaz de entrar e ser retirada da estrutura de enchimento inferior; um cilindro hidráulico de óleo de caixa de molde superior (16) acoplado à caixa de molde superior; um primeiro circuito hidráulico de óleo (81) do cilindro hidráulico de óleo de caixa de molde superior; um cilindro hidráulico de estrutura de enchimento inferior (42) acoplado à estrutura de enchimento inferior; um segundo circuito hidráulico (83) do cilindro hidráulico de estrutura de enchimento inferior; e unidades de acionamentos (37, 80) que movem a placa inferior para cima para executar um processamento de compressão, sendo que o primeiro circuito hidráulico compreende um circuito de contrapressão (82), o qual aplica no cilindro hidráulico de caixa de molde superior uma primeira contrapressão que resiste ao movimento ascendente da caixa de molde superior com relação à placa superior durante o processamento de compressão, e o segundo circuito hidráulico, que possui um circuito de contrapressão (84), o qual aplica no cilindro hidráulico de estrutura de enchimento inferior uma segunda contrapressão que resiste ao movimento descendente da estrutura de enchimento inferior com relação à placa inferior.a molding machine without mold box 1 having: an upper mold box (15) and a lower mold box (17) capable of holding a pairing plate; a drive unit (37) which moves the lower mold box in the vertical direction; a lower filler frame (41) capable of connecting with the lower mold box; an upper plate (25) capable of entering and withdrawing from the upper mold box; a lower plate (40) capable of entering and withdrawing from the lower filling structure; a top mold box hydraulic oil cylinder (16) coupled to the top mold box; a first hydraulic oil circuit (81) of the upper casing hydraulic oil cylinder; a lower filler frame hydraulic cylinder (42) coupled to the lower filler frame; a second hydraulic circuit (83) of the lower filler frame hydraulic cylinder; and drive units (37, 80) that move the lower plate upward to perform compression processing, the first hydraulic circuit comprising a back pressure circuit (82) which applies to the upper mold box hydraulic cylinder a first back pressure that resists upward movement of the upper mold box relative to the upper plate during compression processing, and the second hydraulic circuit, which has a back pressure circuit (84), which applies to the lower filler hydraulic cylinder a second back pressure resisting downward movement of the lower filler structure with respect to the lower plate.
