Abstract
Cylinder mold ejection mechanism, thermoplastic processing technical field is the utility model is related to, refer in particular to one kind during thermoplastic processing, the cylinder mold ejection mechanism of shaped article is released from rear mold.It is made up of preceding mould, rear mold, main nozzle, flow distribution plate, hot mouth, cylinder and needle push rod, preceding mould is provided with die cavity, core in rear mold forms the die cavity of injecting products with the die cavity on preceding mould, main nozzle is installed in rear mold, and hot mouth is connected by the shunt conduit in flow distribution plate, the outlet of hot mouth is connected with the die cavity of injecting products, and cylinder is installed in rear mold, the output end of cylinder is connected with needle push rod, and the other end of needle push rod and the die cavity of injecting products connect.The utility model is due to eliminating rear mold rushing board mechanism, employ oneself existing hot flow path cylinder and serve as rushing board mechanism, original rear mold template thickness greatly reduces, save mold materials and processing cost, linked simultaneously using cylinder, the distance that needle push rod exits can be accurately controlled, greatly saves process time.
Description
Technical field
Thermoplastic processing technical field is the utility model is related to, one kind is referred in particular to during thermoplastic processing, is pushed away from rear mold
Go out the cylinder mold ejection mechanism of shaped article.
Background technology
Hot flow path process technology be by injection machine by the plastic grain after processing with heating method come ensure runner and
The plastics of cast gate are kept molten by being molded.In existing production process, shaping is taken out in typically upper mould movement
Product.But when processing some special products, it can be carried out by the way of upside-down mounting mould.As shown in Figure 1, in production process
In, because main nozzle 5 is arranged in rear mold 2, the plastic grain of molten condition enters hot mouth by the shunt conduit in flow distribution plate 6
7, the die cavity 11 of mould 1 and the interior shaping of the die cavity that the core 21 of rear mold 2 is formed before being injected into.After shaping, in rear mold 2
Push pedal 3 promotes push rod 4 to move, and product A is ejected by rear mold 2, and product A drops, and completes production injection moulding process.But due in upside-down mounting
When being molded into molding product, enter glue position and be located at rear mold 2, be mounted with TOP-TIP in rear mold 2, TOP-TIP is easily with pushing away
Plate 3 and push rod 4 interfere, it is difficult to processing and design, and also inverted mold has push pedal 3 and the structure of push rod 4, and this structure increases
The length of hot runner main nozzle 5 and hot mouth 7, wastes material and the space of mould, while also improves the cost of mould.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and provides a kind of cylinder mould top
Go out mechanism.
The utility model is achieved by the following technical solution：Cylinder mold ejection mechanism, penetrated by preceding mould, rear mold, master
Mouth, flow distribution plate, hot mouth, cylinder and needle push rod are formed, and preceding mould is provided with die cavity, the core in rear mold and the die cavity on preceding mould
The die cavity of injecting products is formed, main nozzle is installed in rear mold, and connects hot mouth by the shunt conduit in flow distribution plate, hot mouth
Outlet is connected with the die cavity of injecting products, and cylinder is installed in rear mold, and the output end of cylinder is connected with needle push rod, and needle pushes away
The other end of bar and the die cavity of injecting products connect.
The utility model employs oneself existing hot flow path cylinder and serves as ledal-pushing machine due to eliminating rear mold rushing board mechanism
Structure, the template thickness of original rear mold greatly reduces, save mold materials and processing cost, while carry out using cylinder
Linkage, can be accurately controlled the distance that needle push rod exits, greatly save process time.
Brief description of the drawings：
Accompanying drawing 1 is prior art construction figure；
Accompanying drawing 2 is the utility model structure chart.
Embodiment：
See accompanying drawing 2, cylinder mold ejection mechanism, by preceding mould 1, rear mold 2, main nozzle 5, flow distribution plate 6, hot mouth 7, cylinder 8 and
Needle push rod 9 is formed, and preceding mould 1 is provided with die cavity 11, and the core 21 in rear mold 2 forms injection production with the die cavity 11 on preceding mould 1
The die cavity of product, main nozzle 5 are installed in rear mold 2, and connect hot mouth 7, the outlet of hot mouth 7 by the shunt conduit in flow distribution plate 6
It is connected with the die cavity of injecting products, cylinder 8 is installed in rear mold 2, and the output end of cylinder 8 is connected with needle push rod 9, and needle pushes away
The other end of bar 9 and the die cavity of injecting products connect.
When the utility model is applied, if the plastic grain of molten condition enters hot mouth by the shunt conduit in flow distribution plate 6
7, and be injected into the die cavity that the preceding die cavity 11 of mould 1 is formed with the core 21 of rear mold 2 and be shaped to product, startup is arranged on rear mold
Cylinder 8 on 2, the needle push rod 9 of the output end of cylinder 8 releases the shaped article in die cavity to be departed from rear mold 2.
