Abstract
The anti-overflow sub-runner system of plastic tray mould, including cope match-plate pattern and lower bolster, solid plate is installed under cope match-plate pattern, solid plate is installed fixed die insert, mould foot is installed on lower bolster, moving platen is installed on mould foot, moving platen is installed moving die insert, gap between moving die insert and fixed die insert constitutes die cavity, flow distribution plate it is equipped with between solid plate and cope match-plate pattern, flow distribution plate is shaped with sub-runner hole, connect under sub-runner hole into Jiao Zui, enter Jiao Zui and connect die cavity, overflow launder it is shaped with on flow distribution plate, anti-overflow plate is set on solid plate, anti-overflow groove is had between anti-overflow plate and flow distribution plate, anti-overflow groove it is shaped with on solid plate, anti-overflow groove connection anti-overflow groove, anti-overflow groove connects into Jiao Zui.The raw material overflowed flows to anti-overflow groove by overflow launder, then flows back to, into Jiao Zuizhong, economize in raw materials by anti-overflow groove, reduces waste, prevents raw material from flowing in mould inside structure, it is to avoid mould inside structural failure, reduces mould maintenance times and cost.
Description
Technical field
The present invention relates to anti-overflow sub-runner (the entering glue) system of a kind 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 range is wide, and consumption is big.Different according to material, pallet is broadly divided into wood pallets, plastic pallet and metal tray.Especially plastic pallet, uses mould of plastics integral molded plastic molding, and production efficiency is high, and low cost is commonly used.Owing to the volume ratio of plastic pallet is relatively big, in order to make whole secondary pallet injection uniformly, intensity is good, the plastic tray mould TOP-TIP (i.e. glue-feeding system) of prior art uses sub-runner structure mostly, by multi-stage diffluence, clicks on glue more, realize injection uniformly, fill full, it is ensured that pallet intensity.But, in actual production, due to hot flow path multi-stage diffluence, the area of runner increases, and is easily caused raw material overflow, flows into and causes parts damages in mould inside structure, maintenance trouble.
Summary of the invention
The invention aims to overcome the shortcoming of prior art, it is provided that one arranges anti-overflow plate outside sub-runner frame, prevent raw material from flowing out outside runner, it is to avoid mould inside structural failure, save the anti-overflow sub-runner system of the plastic tray mould of maintenance cost.
The technical scheme of the anti-overflow sub-runner system of plastic tray mould of the present invention is: include upper mould plate and lower bolster, solid plate is installed under cope match-plate pattern, solid plate is installed fixed die insert, mould foot is installed on lower bolster, moving platen is installed on mould foot, moving platen is installed moving die insert, gap between moving die insert and fixed die insert constitutes die cavity, it is equipped with flow distribution plate between described solid plate and cope match-plate pattern, flow distribution plate is shaped with sub-runner hole, connect under sub-runner hole into Jiao Zui, enter Jiao Zui and connect die cavity, it is characterized in that being shaped with overflow launder on described flow distribution plate, anti-overflow plate is set on solid plate, anti-overflow groove is had between anti-overflow plate and flow distribution plate, anti-overflow groove it is shaped with on solid plate, anti-overflow groove connection anti-overflow groove, anti-overflow groove connects into Jiao Zui.
The anti-overflow sub-runner system of the plastic tray mould of the present invention, it is mainly characterized by being 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, anti-overflow groove it is shaped with on solid plate, anti-overflow groove connection anti-overflow groove, anti-overflow groove connects into Jiao Zui, during injection, 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, reduce 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 sub-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.
