Abstract
The invention discloses an anti-overflow branch runner system of a plastic tray mold. The anti-overflow branch runner system comprises an upper mold plate and a lower mold plate, wherein a stationary mold plate is arranged below the upper mold plate; a stationary embedding block is arranged in the stationary mold plate; a mold foot is arranged on the lower mold plate; a movable mold plate is arranged on the mold foot; a movable embedding block is arranged in the movable mold plate; a clearance between the stationary and movable embedding blocks defines a mold cavity; a distribution plate is arranged between the stationary mold plate and the upper mold plate; a distribution channel hole is formed in the stationary mold plate; a rubber inlet nozzle is connected below the distribution channel hole and is communicated with the mold cavity; an overflow groove is formed in the distribution plate; an anti-overflow plate is arranged on the station mold plate; an anti-overflow groove is formed between the anti-overflow plate and the distribution plate; an anti-overflow communication groove is formed in the stationary mold plate and is communicated with the anti-overflow groove and the rubber inlet nozzle. Overflowed raw materials flow to the anti-overflow groove through the overflow groove and flow back to the rubber inlet nozzle through the anti-overflow communicating groove; the raw materials are saved, the waste is reduced; the raw materials are prevented from flowing into the inside structure of the mold; the damage of the inside structure of the mold is avoided and the maintenance time and cost are reduced.
Description
Technical field
The present invention relates to a kind of anti-overflow runner (entering glue) system of plastic tray mould, belong to mould of plastics field.
Background technology
At present, pallet is widely used in transport, warehousing and airport, stevedoring goods etc., and the scope of application is wide, and consumption is large.Different according to material, pallet is mainly divided into wood pallets, plastic pallet and metal tray.Especially plastic pallet, adopt mould of plastics integral molded plastic shaping, production efficiency is high, and cost is low, is generally used.Because the volume ratio of plastic pallet is comparatively large, in order to make whole secondary pallet injection moulding even, intensity is good, the plastic tray mould TOP-TIP (i.e. glue-feeding system) of prior art adopts runner structure mostly, and by multi-stage diffluence, multiple spot enters glue, realize injection moulding even, fill full, ensure pallet intensity.But in actual production, due to hot flow path multi-stage diffluence, the area of runner increases, and easily causes raw material overflow, flows in mould inside structure and causes parts damages, maintenance trouble.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art, providing a kind of and anti-overflow plate is set outside runner frame, prevent raw material from flowing out outside runner, avoid mould inside structural failure, save the anti-overflow runner system of the plastic tray mould of maintenance cost.
The technical scheme of the anti-overflow runner system of plastic tray mould of the present invention is: comprise upper mould plate and lower bolster, under cope match-plate pattern, solid plate is installed, in solid plate, fixed die insert is installed, lower bolster is installed mould pin, mould pin installs moving platen, in moving platen, moving die insert is installed, gap between moving die insert and fixed die insert forms die cavity, flow distribution plate is equipped with between described solid plate and cope match-plate pattern, runner hole is shaped with in flow distribution plate, connect under runner hole into Jiao Zui, enter Jiao Zui and be communicated with die cavity, it is characterized in that described flow distribution plate is shaped with overflow launder, solid plate is arranged anti-overflow plate, anti-overflow groove is had between anti-overflow plate and flow distribution plate, solid plate is shaped with anti-overflow groove, anti-overflow groove is communicated with anti-overflow groove, anti-overflow groove is communicated with into Jiao Zui.
The anti-overflow runner system of plastic tray mould of the present invention, main feature is shaped with overflow launder on described flow distribution plate, solid plate arranges anti-overflow plate, anti-overflow groove is had between anti-overflow plate and flow distribution plate, solid plate is shaped with anti-overflow groove, anti-overflow groove is communicated with anti-overflow groove, anti-overflow groove is communicated with into Jiao Zui, during injection moulding, the raw material overflowed flows to anti-overflow groove by overflow launder, flow back to into Jiao Zuizhong by anti-overflow groove again, both raw material had been saved, cut the waste, prevent again raw material from flowing in mould inside structure, avoid mould inside structural failure, reduce mould maintenance times and cost.
The anti-overflow runner system of plastic tray mould of the present invention, described flow distribution plate is rice font, and overflow launder is the distribution of rice font, and the Internal periphery of described anti-overflow plate is corresponding with flow distribution plate.

Fig. 1 is the anti-overflow runner system architecture schematic diagram of plastic tray mould of the present invention;
Fig. 2 is rice font flow distribution plate schematic diagram of the present invention;
Fig. 3 is that rice font flow distribution plate of the present invention and anti-overflow plate assemble schematic diagram.
Detailed description of the invention
The present invention relates to a kind of anti-overflow runner system of plastic tray mould, as shown in Fig. 1-Fig. 3, comprise upper mould plate 1 and lower bolster 2, solid plate 3 is installed under cope match-plate pattern, fixed die insert 4 is installed in solid plate, lower bolster is installed mould pin 5, mould pin is installed moving platen 6, moving die insert 7 is installed in moving platen, gap between moving die insert 7 and fixed die insert 4 forms die cavity, flow distribution plate 8 is equipped with between described solid plate 2 and cope match-plate pattern 1, runner hole 9 is shaped with in flow distribution plate 8, runner hole connects for 9 times into glue mouth 10, enter glue mouth 10 and be communicated with die cavity, described flow distribution plate 8 is shaped with overflow launder 11, solid plate 3 is arranged anti-overflow plate 12, anti-overflow groove 13 is had between anti-overflow plate 12 and flow distribution plate 8, solid plate 3 is shaped with anti-overflow groove 14, anti-overflow groove 13 is communicated with anti-overflow groove 14, anti-overflow groove 14 is communicated with into glue mouth 10.The main feature of this programme is shaped with overflow launder 11 on described flow distribution plate 8, solid plate 3 arranges anti-overflow plate 12, anti-overflow groove 13 is had between anti-overflow plate 12 and flow distribution plate 8, solid plate 3 is shaped with anti-overflow groove 14, anti-overflow groove 13 is communicated with anti-overflow groove 14, anti-overflow groove 14 is communicated with into glue mouth 10, during injection moulding, the raw material overflowed flows to anti-overflow groove 13 by overflow launder, flow back in glue mouth 10 by anti-overflow groove 14 again, both raw material had been saved, cut the waste, prevent again raw material from flowing in mould inside structure, avoid mould inside structural failure, reduce mould maintenance times and cost.Described flow distribution plate 8 is rice font, and overflow launder 11 is distribution in rice font, and the Internal periphery of described anti-overflow plate 12 is corresponding with flow distribution plate 8.
