Utility model content

The utility model is in order to overcome the deficiency that in prior art, the aspect such as isostasy, material amount accuracy of mould of plastics pay-off when to multiple die cavity feed is short of to some extent, the pay-off of isostasy, material amount accuracy and the feature of environmental protection when a kind of energy effective guarantee feed efficiency, feed are provided.

To achieve these goals, the utility model is by the following technical solutions:

Pay-off is concentrated in a kind of injection moulding, comprise feed portion, feeding dispenser, described feed portion comprises feed tank, big up and small down trapezoidal of described feed tank lower section, described feed portion is provided with quantitative tapping equipment, described quantitative tapping equipment comprises the feed opening interconnecting, punishment in advance portion, discharging portion, described discharging portion is in the below of punishment in advance portion, described punishment in advance portion is provided with the on-off valve for controlling the punishment in advance portion material amount of flowing through, described feed opening one side is provided with discharge gate, described discharge gate is provided with end cap, described end cap is fixedly covered tightly on discharge gate by wing nut, described discharging portion comprises an air inlet and a discharging opening, described air inlet is provided with screen pack, described discharging opening towards contrary with feed opening place one side, described feeding dispenser comprises feed pipe, connect the feed-inputing branched pipe of feed pipe, described feed-inputing branched pipe is provided with some feed pipes for feeding, described feed pipe outer end all connects to be then used in provides the negative-pressure vacuum of feeding suction pump, described feed pipe docks with discharging opening, described feed pipe, feed-inputing branched pipe, in feed pipe, be equipped with spiral steel-wire carcass.

As preferably, described on-off valve is magnetic valve.Be beneficial to the interval time of controlling break-make, good stability.

As preferably, described feed pipe is vertical, the position of described feed-inputing branched pipe and feed pipe tie point along near feed pipe to raising one by one away from the direction of feed pipe.From feed pipe more away from, the charging degree of depth is just larger relatively, carry out suitable making up by feed-inputing branched pipe and feed pipe tie point height different, thereby ensureing that true length that each feed pipe is exported to feed pipe differs can be not excessive, each overpressure while ensureing simultaneously unblank of feed-inputing branched pipe work, duty are comparatively balanced, safeguard work process stable.

The beneficial effects of the utility model are: can utilize negative pressure fast the plastics of initial given material amount to be sucked to each die cavity, and not be interrupted in process, operating efficiency is high; When feed, the true length of each pipeline is more or less the same, and therefore can ensure that the suction of each pipeline is approaching and enough, so harmonious good; When feed, after preliminary feed completes, can continue suction, ensure that all material can enter die cavity.
