Description
Technical field
The utility model is related to a kind of push pedal pneumatic jack injection mold, available for the plastic outer product such as shell, end cap, cover plate
Injection forming mold field.
Background technology
It is all plastic products to have many things in our daily lifes now, such as automobile, TV, mobile phone etc. almost I
Have moulding on thinkable product, some mouldings are that structural member is mounted in interiors of products, and some mouldings are functors
Specific function is played in the product, and most moulding also having is that appearance member is mounted in outside product, for these appearance members
Injecting products, because its appearance has aesthetic, will not allow to be placed on surface and pour the class of point, push rod etc. one and can produce vestige
Feature.This class outward appearance injecting products typically requires to enter to pour using the mode poured in down a chimney, i.e., enter to pour from dynamic model side.So as to can guarantee that
Product appearance is not had into cast gate and push rod vestige.
It is, according to upside-down mounting mould design common in industry, to use oil cylinder pushing typically to do the injection mold that outward appearance requires at present
Ejector retainner plate is ejected, and the ejecting mechanism such as push rod, oblique top, jacking block is arranged on ejector retainner plate, because have 2 pieces of ejector retainner plates plus needs
The distance of ejection, the comparison that general mould square iron can all be done is high, can accomplish more than 120mm height substantially, set in this approach
The general mould of mould of meter is partially thick.It is also corresponding lengthening that same hot flow path, which fills mouth, typically accomplishes 450mm length or so, so meeting
Make injection pressure loss very big, often from the injection machine of larger specifications and models.Because this design needs to eject distance,
So a segment distance is had between moving platen and ejector retainner plate vacantly, in order to avoid because hanging cause to be caused template greatly by injection power
Deformation, common way can install support column additional between, support shuttering, but so sometimes injection pressure than it is larger when template still
It can deform, cause injecting products to produce flash abnormal.A large amount of push rod ejecting products are needed to use additionally, due to such mould, equally
Many exceptions are will also result in, such as common product top is white, it is stuck etc. abnormal to push up convex and thimble.
Therefore, in face of these variety of problems for running into, it is necessary to which we are by continuous summary problem and for various problems
Technically improve and innovate, change the design concept of current back flowing mold.
Utility model content
The purpose of this utility model is：The problem of existing for above-mentioned prior art, proposes a kind of structure design more
The push pedal pneumatic jack injection mold of optimization, easy to maintenance, performance stabilization and low cost.
In order to reach object above, a kind of push pedal pneumatic jack injection mold that the utility model is related to, including it is top clamping plate, fixed
Template, Bottom clamp plate, mavable module core, mavable module core mold insert, hot flow path running gate system and cooling system；It is characterized in that：Also include
One group of L-shaped pneumatic jack in die core insert, be arranged between Bottom clamp plate and solid plate and with pushing away that its structure matches
Plate and the cylinder system for being arranged on Bottom clamp plate two ends；The vertical bar of the L-shaped pneumatic jack from top to bottom sequentially pass through mavable module core,
It is connected after the stomata opened up on Bottom clamp plate with the transverse bar of its bottom；The baric systerm power of the transverse bar and injection machine connects
Connect；The push pedal is set in outside mavable module core and 1 °~3 ° of the fit angle between mavable module core；The oil cylinder top of the cylinder system
Connector is installed on bar；The connector is mounted by dovetail groove and push pedal two ends.
The technical scheme that the utility model is further limited as：The cooling system includes one group of water channel be arrangeding in parallel,
The distance between adjacent two water channels are 4~6 times of water channel diameter, and water channel is more than at least 2 times distances of its diameter apart from die cavity.
Further, the push pedal is greater than 1mm when pushing away product with the sectional area of product contact surface.
Further, the cylinder system includes 2 oil cylinders, 2 connectors, 2 oil nozzles, 2 oil cylinder blocks and oil
Road system.
Further, the pneumatic jack quantity is 4.
Further, the hot flow path running gate system is the needle valve type hot runner on Bottom clamp plate, including is shunted
The parts such as plate, heater, nozzle, hydraulic cylinder, terminal box, relay are constituted.
Further, also including being fixedly mounted on above die holder plate and the thermal insulation board below Bottom clamp plate.
Further, also including the centring ring on Bottom clamp plate.
The beneficial effects of the utility model：The part that so mould bears injection pressure is solid steel and injection molding machine
Seat board, has sufficiently large power and intensity to ensure that template is indeformable, so as to avoid mold injection molding from producing flash, so this practicality
The mold injection molding of new making all without there is flash appearance, will not occur thimble it is stuck, push up it is convex, also do not occur die venting
The bad phenomenon such as cause product to burn, the utility model can realize the automating of Making mold production, easy-maintaining maintenance, hairless
Side, without the high-end requirement such as material head.
Its mold thickness of push pedal pneumatic jack mould of the present utility model reduces 40%, and mould structure cancels support block cushion block and two
Block ejector retainner plate uses push pedal instead, and the part that such mould bears injection pressure is the seat board of solid steel and injection molding machine, has enough
Big power and intensity ensure that template is indeformable, eject it is also more stable, optimize ejector retainner plate ejection top it is white the shortcomings of, so as to avoid
Mold injection molding produces flash, will not occur that thimble is stuck, it is convex to push up, and does not also occur that die venting is bad to cause product to burn
Phenomenon, the utility model can realize Making mold production automate, it is easy-maintaining maintenance, without flash, without material head etc. it is high-end will
Ask.Mold insert coordinates section to need to do fit angle in push pedal and mould, because push pedal and interior mold insert can produce motion, does fit angle
Prevent because motion when high-speed friction produce heat workpiece burn, while be also possible to prevent because processing or assembly precision not
Enough cause mould stuck.The mavable module core of determining of push pedal pneumatic jack mould is replaced using moving platen is determined, and can also increase the breaking face of die
Product, so not only can preferably control in machining accuracy, the cost that subsequent artefacts cut flash be reduced, in production mistake
The yields 60% of product is effectively increased in journey.Relatively conventional hot flow path contraction in length 60%, the cold burden in hot mouth subtracts
Lack 50%, hot mouth price also reduces 40%, often covered TOP-TIP and reduce more than about 10000 yuan of cost.We are by this skill
Art is successfully tried to apply on set end cover dies more, in mould production cost, comprehensive to reduce more than 30%, per mold into
Originally 30,000 yuan can be saved；500,000 moulds are produced by every mold, production cost can save 50,000 yuan；It is annual open at least 10 sets with
Upper similar mould, every year can be with cost-effective more than 800,000 yuan.In terms of trial production situation, this several mold compares Conventional flip
Mould is stable, and efficiency improves 20%, highly promoted the use of, and substitutes existing mold design.
