Description
Technical field
The invention belongs to mould applications, and in particular to a kind of ejector sleeve liftout attachment.
Background technique
Mold is important one of manufacturing equipment in automobile lamp manufacturing process.The product that the quality of mold produces it
It is whether qualified, be one of the factor being affected to it, the problem of product quality and qualification rate in mold influence 50% or more.
The success or not of mould structure design, directly affects product quality and the cost of labor etc. in later product production process.Many institutes
Known injection mold is made of seven big systems: (1) part for supporting (fixation) system: meeting the requirement on mould structure and be arranged
(such as: fixed plate moves/solid plate, fastener, support plate and attachment screw etc.).(2) it is oriented to (resetting) system: in order to guarantee
The guiding parts that can be precisely aligned and be arranged when dynamic model and cover half closure, plays guiding and positioning function, it is by guide pillars and bushes
Composition, some molds are provided with guiding parts also on liftout plate, guarantee that demoulding mechanism movement is steady reliable.(3) molding system
System: moulding material shape, structure, the part of size, usually by type core (punch-pin), concave die cavity and thread core, edge are assigned
Block etc. is constituted.(4) running gate system: it is the channel that molten plastic is guided into closed mould cavity by nozzle of injector, usually by mainstream
Road, runner, cast gate and cold burden well construction.(5) it temperature-controlling system: in order to meet requirement of the injection molding technique to mold, needs
The device for having mould temperature controlling system (such as: cooling water, hot water, hot oil and electric heating system) that mold temperature is adjusted.(6)
Ejection system: the device of plastic and running gate system demoulding is realized, there are many structure type, most common to have mandril, push pipe, top plate
And the demoulding mechanisms such as pneumatic ejection, generally by mandril, release link, catapult, mandril fixed plate, top plate (apical ring) and top plate guide post,
The composition such as guide sleeve.(7) in order to which the gas in die cavity to be smoothly discharged, air discharge duct often exhaust system: is opened up at mold parting surface
Currently used ejection system substantially has following several: jacking block (can be divided into straight jacking block, slanted kicking block) and mandril (can
It is divided into round top rod, flat mandril, square mandril), existing ejecting structure usually has the disadvantages that 1, processing: existing frequently-used top
Out no matter round top rod, flat mandril, square mandril, ejector sleeve ejection etc. is all made as monolithic construction.Its drawback is greater than when mandril length
It is relatively difficult once processing when 500mm, since mandril is elongated in process, directly affect the rigidity of mandril, process
In be easy to cause mandril to deform.2, use: due to ejecting frequently, usually there is plucking, deformation in use in ejector sleeve ejection
It needs replacing, original ejector sleeve form needs integral replacing, causes the waste in working hour, cost.3, monoblock type ejector sleeve is expensive.
