Abstract
The utility model relates to a pressurizing reset mechanism for a two-template injection molding machine, which comprises a machine frame, wherein an injection system, a mold opening and closing device, a mold locking mechanism and an ejector are arranged on the machine frame, the mold opening and closing device comprises a fixed template and a movable template, molds are respectively arranged in each template, a mold opening and closing oil cylinder is arranged on one template in the two, an opening and closing piston rod of the mold opening and closing oil cylinder is connected with the other template, the mold locking mechanism comprises a pressurizing plate arranged in the fixed template or/and the movable template, the pressurizing plate is provided with a pressurizing oil cylinder, and the pressurizing oil cylinder carries out pressurizing and mold locking on the pressurizing plate. The pressurizing reset mechanism is characterized in that a rest oil cylinder is arranged on the fixed template or/and the movable template, and a reset piston rod of the reset oil cylinder is connected with the pressurizing plate. Compared with the prior art adopting a reset spring, the pressurizing reset mechanism has the advantages that the action is more stable and more reliable, and the service life is longer.
Description
Technical field
The utility model relates to a kind of supercharging resetting-mechanism of two template injection molding machines, belongs to the plastics machinery field.
Background technology
The primary structure of prior art two template injection molding machines comprises frame; injection device is installed on the frame; folding mould device; clamping mechanism and liftout attachment; described folding mould device comprises fixed form and collapsible form; difference installation mold in each template; the folding mould oil cylinder is installed on the template in two templates; the piston rod of folding mould oil cylinder connects another piece template; the concrete scheme of described clamping mechanism has multiple; in wherein a kind of wherein one or two templates that are included in two templates pressuring plate is installed all; pressuring plate has pressurizing cylinder, and pressurizing cylinder is to pressuring plate supercharging locked mode.Owing to be subjected to the restriction of installing space, described pressurizing cylinder is unidirectional pressurizing cylinder, just pressurizing cylinder can only be to the pressuring plate supercharging, can not reset, pressuring plate relies on back-moving spring to reset, and the shortcoming of its existence is: after spring uses a period of time, and the elastic instability of spring, the elastic force deficiency, service life is short.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of employing oil cylinder as power, and the pressuring plate homing action is stable, reliable, two template injection molding machine supercharging resetting-mechanisms of long service life.
The technical scheme of the utility model two template injection molding machine supercharging resetting-mechanisms is: comprise frame; injecting systems is installed on the frame; folding mould device; clamping mechanism and liftout attachment; described folding mould device comprises fixed form and collapsible form; difference installation mold in each template; the folding mould oil cylinder is installed on the template in two templates; the folding piston rod of folding mould oil cylinder connects another piece template; described clamping mechanism comprises fixed form or/and pressuring plate is installed in the collapsible form; pressuring plate has pressurizing cylinder; pressurizing cylinder is to pressuring plate supercharging locked mode; it is characterized in that described fixed form or/and drawback cylinder is installed on the collapsible form, the return piston bar of drawback cylinder connects pressuring plate.
The utility model discloses a kind of two template injection molding machine supercharging resetting-mechanisms, described fixed form is or/and install drawback cylinder on the collapsible form, the return piston bar of drawback cylinder connects pressuring plate, after drawback cylinder has been arranged, after pressuring plate supercharging locked mode moves forward, drive pressuring plate by drawback cylinder and draw back and reply the position, compare with the existing back-moving spring that adopts, move more stable, reliable, long service life.
Two template injection molding machine supercharging resetting-mechanisms of the present utility model, be connected by guide rod between described fixed form and the collapsible form, described fixed form is or/and be connected by guide rod between collapsible form and the pressuring plate, be provided with guide pin bushing between guide rod and the pressuring plate, guide rod has been arranged, pressuring plate travels forward when supercharging steadily, and guide pin bushing has been arranged, and prevents that pressuring plate wearing and tearing and guide rod from producing the gap.
