In and with 16 tip contact of spring, mold using sub-marine gate feed.Sub-marine gate has：Keep the plastics into cavity molten
Body is to press to inserts, can reduce the stress of inserts mandril, avoid melt from entering in inserts delthyrium, plastic is caused to scrap；It does not influence
The presentation quality of plastic is conducive to the gas in cavity being discharged from die joint.Because inserts is without any machining, each section
Scale error and deformation are larger, when mold positions, consider to utilize inserts shank φ 7mm pin holes steel ball spring localization machine first
Structure carries out coarse positioning, then larger, heavier for inserts, and shank and feature eccentric above and below shape, on the end face of inserts
Design assistant jacking mechanism constitutes positioning and the compression of inserts together with steel ball spring detent mechanism, to ensure that inserts had been molded
Deflection and material leakage are not generated in journey.It uses movable inserts mandril 1 and inserts mandril 2 14 and adds spring 16 in tail portion
Structure, auxiliary withstand the end face of inserts 4, realize positioning and the compression of inserts.It avoids and uses other structures, such as design this
Structure is arranged on moving platen, and due to being limited by dynamic model plate thickness, movable mandril is shorter, and the decrement of spring is less, mandril
The phenomenon that being easy to suppress dead or reset failure during use.This structure, it is simple and reliable for structure as long as connection and reasonable arrangement, it is living
The phenomenon that dynamic mandril is without dead or reset failure is suppressed.Before molding, manually inserts 4 is put into core set 3, by steel ball spring localization machine
Structure carries out coarse positioning, when molding, since inserts mandril is longer, will initially strike the end face of inserts 4, and under spring force
Inserts 4 is withstood, can prevent last clamping process because shock and vibration makes inserts deflection in this way, can also make bottom surface and the core of inserts
The end face reliable contacts of set, then, release link 18 makes transfer bar mechanism reset.When injection moulding, due to using sub-marine gate into
Material, plastic melt withstand inserts to press to inserts and movable mandril, and inserts not will produce deflection and material leakage.After molding, die sinking

In the casting workpiece chamber in designing mold, under the premise of not influencing properties of product, casting can be locally increased
Deflecting degree avoids design loose piece.
The radius of corner R (mm) of workpiece chamber is calculated as follows in mold：
The thickness (mm) of δ, δ ' in formula --- casting adjacent wall
When determining running gate system sectional area, the minimum sectional area of running channel is usually first calculated, it is then true further according to proportionate relationship
The sectional area of other fixed units.
The duration of pouring is shorter than sand casting by 20%~40%.
τ in formula --- the duration of pouring (s)
H --- casting height (cm)
V --- molten metal average rate of climb (cm/s) in cavity
For Al alloys andMg alloys casting：
δ in formula --- casting section thickness (cm)
V in formula --- molten metal average speed (cm/s) in running channel minimum sectional area
The weight (g) of W --- casting
Density (the g/cm of ρ --- molten metal3)
τ --- the duration of pouring (s)
Minimum sectional area (the cm of Amin --- running channel2)
The size of metal mold cavity and core can be calculated as follows：
Ax=(+2 δ of A+A ε) ± Δ Ax
Dx=(A+A ε -2 δ) ± Δ Dx
Ax in formula, Dx --- it is respectively the size of cavity and core
A, D --- it is respectively the nominal size of the shape and endoporus of casting
The linear shrinkage ratio of ε --- casting material
The thickness (generally taking 0.1mm~0.3mm) of δ --- dope layer
Δ Ax, Δ Dx --- metal mold machining tolerance.
Tradition is all to use to be cooled down under natural conditions, or just pass through work when it is completely cooling after pouring
Workpiece is removed from the molds by tool places cooling in environment cooling or special in the natural environment, this not only be easy to cause mould
Deformation is taken out when having uncolled, and cannot guarantee that cooling quality, and this programme is then that ventilation opening 20 is arranged in a mold, is led to
It crosses to direct wind into mold and be cooled down, and the raw material that use is molten conditions when due to casting, if ventilation opening 20 is set
The workpiece that is located too close to of meter reserves chamber, and raw material will be caused to flow out so that and structure is destroyed, and chamber is reserved too remotely from workpiece,
Cooling effect is again bad, for this purpose, specially the height of ventilation opening 20 is arranged between the movement locus of moving platen 6, in moving platen 6
Ventilation opening 20 can be completely enclosed by moving to when being contacted with solid plate 5, raw material in the molten state workpiece reserve chamber at
After type, moving platen 6 moves downward, and exposes until by ventilation opening 20, then the gas that can be passed through that treated into ventilation opening at
Type workpiece is cooled down, and since workpiece is molded, can be born wind-force and be brushed power to its surface, ensure that the quality of workpiece, make
Obtaining workpiece can be quickly cooled down, safety higher, reasonably control temperature, dimension scale control so that its is easily-controllable, extends
Service life.
