Description

The transfer mould of sealing ring on hydraulic press
Technical field
The present invention relates to mould applications, be specifically related to the transfer mould of sealing ring on a kind of hydraulic press.
Background technology
Mould, in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product.It mainly makes blank become the instrument of the product having given shape and size under external force.Be widely used in stamping-out, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and in the compression moulding of goods such as engineering plastics, rubber, pottery or the formed machining of injection moulding.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank be separated (stamping-out) by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and cover half (or punch and die) two parts, the two partable.Take out product time separately, make blank inject mold cavity when closing up and be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, all has higher requirements to structural strength, rigidity, case hardness, surface roughness and machining accuracy, and the development level that mould is produced is one of important symbol of machine-building level.
Acting as of hydraulic system increases active force by changing pressure.A complete hydraulic system is made up of five parts, i.e. dynamical element, executive component, control element, auxiliary element and hydraulic oil.Hydraulic system can be divided into two classes: Hydraulic Power Transmission System and hydraulic control system.Hydraulic Power Transmission System is to transmit dynamic force and motion for major function.Hydraulic control system then will make hydraulic system output meet specific performance requirement, and usually said hydraulic system mainly refers to Hydraulic Power Transmission System.Wherein sealing ring is particularly important, and sealing ring can prevent the inside and outside leakage of hydraulic oil and prevent the foreign matter impouring hydraulic systems such as dust, air, metal, and it is related to the service behaviour of hydraulic pump and the stationarity of hydraulic actuator motion.Due to the importance of sealing ring, also particularly important for the mould producing sealing ring in a large number, the usual complex structure of existing mould, inconvenience dismounting, needing to destroy its overall structure when taking out plastic, improve production cost; And complex operation, reduce production efficiency.
Summary of the invention
The invention is intended to provide the transfer mould of sealing ring on a kind of production cost is low, production efficiency is high hydraulic press.
Achieve the above object, base case of the present invention is as follows: the transfer mould of sealing ring on hydraulic press, comprises power unit and machining cell, and described power unit comprises pressing plate and compression leg, be provided with upper guide post and feed compartment in described pressing plate, described compression leg and feed compartment are slidably connected; Described machining cell comprises cope match-plate pattern, lower bolster and punch, symmetrical charging hole is respectively equipped with along cope match-plate pattern center line in described cope match-plate pattern, lower guide pillar is provided with in described lower bolster, described upper guide post, lower guide pillar are all slidably connected with cope match-plate pattern, described punch is fixedly connected with lower bolster, and the top of punch and cope match-plate pattern offset; Described compression leg, charging hole, cope match-plate pattern, lower bolster and punch surround forming cavity.
The principle of base case: during operation, first adds in feed compartment by the raw material after melting; Then promote compression leg to move down, when compression leg and cope match-plate pattern offset, pressing plate is connected by upper guide post with cope match-plate pattern, cope match-plate pattern is connected by lower guide pillar with lower bolster, forming cavity is surrounded by compression leg, charging hole, cope match-plate pattern, lower bolster and punch, raw material is flow regime under the effect of the pressure and is full of forming cavity, is shaped by plastics hardening by cooling; Finally power unit and cope match-plate pattern are taken out, can plastic be obtained.
The advantage of base case: be provided with independent feed compartment in this programme, facilitate the storage of raw materials, compares an another preparation material container, has saved production cost; Pressing plate and cope match-plate pattern are slidably connected by upper guide post, cope match-plate pattern and lower bolster are slidably connected by lower guide pillar, all for convenience detach after injection-compression molding, compare to destroy mould structure and take out plastic, have effectively saved production cost; And mainly through compression leg extruding raw material, raw material is flow regime under the effect of the pressure and is full of forming cavity, is shaped by plastics hardening by cooling, and its integrated operation is convenient, effectively raises production efficiency.
Preferred version one: based on the preferred version of scheme, described charging hole reduces from top to bottom gradually, by above-mentioned setting, when compression leg extruding raw material, because charging hole reduces from top to bottom gradually, make the better effects if extruded, more easily fill up forming cavity, effectively save the time.
Preferred version two: the both sides of described pressing plate, the both sides of cope match-plate pattern are equipped with handle, by above-mentioned setting, after injection-compression molding, takes pressing plate and cope match-plate pattern away by handle, has more feel, more laborsaving.
Preferred version three: the preferably preferred version of two, is provided with pin in described lower bolster, and described pin is fixedly connected with punch, by above-mentioned setting, when needs injection-compression molding, pin is fixedly connected with lower bolster and punch, effective restriction lower bolster and punch movement in the horizontal direction; When after injection-compression molding, pin is for convenience detach.
