Description
Technical field
The present invention relates to a kind of compression tool, it is mainly used in the pressure of the poor plastics of the thermoplastic mobility such as wear-resisting, corrosion-resistant
It is moulded into type.
Background technology
In current corrosion resistant, wear-resisting plastic pump production process, generally using the good supra polymer of anticorrosive anti-wear performance
Weight northylen material is molded and lining, because the thermoplastic temperature flowing is very poor, pressure transmission during plastics single way stempressing
It is not smooth, away from pressure head, remotely pressure is small, plastics are loose, can not be molded, the molding percentage of A-class goods is relatively low always, particularly in manufacture pump case
Etc. in complex-shaped workpiece fabrication, can only sacrifice hydraulic performance is made into annular channel, otherwise will be unable to shaping.
The content of the invention
It is an object of the invention to provide a kind of pinoplastics moldings, the pinoplastics moldings are compression moulding material mobility is poor or structure
The problem of during complicated pressing, being not in that plastics are loose, can not be molded.
To achieve the above object, the invention provides following technical scheme：A kind of compression tool, including core and core
Periphery and the spaced external mold of core, the folder chamber between the external mold and core are on the die cavity for constituting mould, the external mold
Provided with least two pressing molds, composition is slidably matched relatively between the pressing mold and external mold and pressing mold constitutes extruding action to die cavity,
Each pressing mold is located remotely from each other setting in die cavity periphery.
The technical effects of the invention are that：Using the composite coining technology of multidirectional pressurization, mould the thermoplasticity of poor fluidity
During material molding can progressively uniform-compression from multiple directions, the plastics of melting are pressed into die cavity, poor fluidity is solved well
Plastics single way stempressing when pressure transmission it is not smooth, away from the pressure head problem, mould such as remotely pressure is small, plastics are loose, can not be molded
The quality and the percentage of A-class goods of compacting product are significantly improved.

Cylinder is fitted, and the U-type groove of the flange shape structure 24 is to constitute the lower extrusion chamber b2 slided up and down for the dip mold 30b of pump case 20,
The bottom land of the U-type groove, which is provided with through hole, the through hole, is provided with push rod 31, and the push rod 31 is constituted with through hole and is slidably matched,
The upper end of push rod 31, which is resisted against on the dip mold 30b of pump case 20, to be used to drive dip mold 30b to move up and down.
Further, as shown in Fig. 2 the inner side of the U-shaped flange shape structure 24 is provided with boss, the core print 10
The face of cylinder is held to be provided with radial flange, the boss rides against on radial flange and affixed by bolt, and the type block 11 is hooked
It is affixed by bolt between the upper end of the flange shape structure 24, the boss and type block 11 of flange shape structure 24.
It is preferred that, the core print 10 is in up-narrow and down-wide ladder shaft-like, and step is concordant with the upper surface of type block 11.
The specific work process of this compression tool is as follows：
Dip mold 30b is put into lower die-sleeve 22b U-shaped groove first, pump case 20 is then disposed across lower die-sleeve 22b
On, the pilot hole for being used for connecting end cap is natively provided with the lower surface of pump case 20, therefore only need to be with bolt is by lower die-sleeve 22b and is somebody's turn to do
Pilot hole connection can be achieved with the fixation between pump case 20 and lower die-sleeve 22b；Now need that partly plastic particle first is poured into lower mould
In the U-type groove for covering 22b, prevent that plastic grain can not fall into through roundabout die cavity a and fill up lower end extruding after the loading of type block 11
Chamber b2；Then type block 11 is put into pump case 20, the lower end of type block 11 is resisted against the upper end blending bolt of flange shape structure 24 by two
Person is affixed, and now pump case 20, lower die-sleeve 22b, the three of type block 11 are linked to be an entirety；Then by pump case 20, lower die-sleeve 22b, type
The entirety that the three of block 11 is linked to be is set on core print 10 blending bolt by the radial flange of the lower end of core print 10 and flange shape knot
The boss of structure 24 is affixed；Then Upper Die-sleeve 22a is connected on the upper surface of pump case 20, outlet die sleeve 23 is connected to going out for pump case 20
At mouthful on the end face of short tube 21, by outlet core 12 and outlet pressing mold 30c insertions outlet die sleeve 23；Second can be now carried out to add
Material, plastic grain is poured at the annular housing opening between Upper Die-sleeve 22a and core print 10, then top die 30a is filled
Enter in upper extrusion chamber b1, plastic grain is compacted by top die 30a；Again by whole 90 ° of die flip, outlet mold is set to cover 23 opening
Upward, outlet core 12 and outlet pressing mold 30c are taken out, third time charging is carried out at the outlet opening of die sleeve 23, will after charging
Outlet core 12 and outlet pressing mold 30c are again loaded into, and plastic grain is compacted by outlet core 12 and outlet pressing mold 30c, so far, dress
Mould is completed；The mould assembled is put into heating stove heat, plastic grain is changed into molten condition, mould is then lifted into pressure
Compression moulding is carried out on machine.
During molding, hydraulic press is first pressurizeed from top by top die 30a to plastics, and mould is sling followed by hydraulic press backhaul
Tool, will push mould bases 32 and is placed in below mould, the push rod 31 pushed on mould bases 32 is withstood down by the through hole of flange shape structure 24
