Abstract
The utility model discloses a Tina multi-nozzle tip hot runner system, and the system is characterized by comprising a splitter plate, a main injection nozzle, a sliding gasket, a central gasket, a central pin, an anti-rotating pin and a heat nozzle. A plurality of runners are formed inside the heat nozzle; the runners are split by a flange and are finally butted with a nozzle tip by the same aperture, so that plastic enters the main injection nozzle from a gun barrel of an injection molding machine, then is split by entering the splitter plate and then enters the heat nozzle; the heat nozzle splits the plastic and then the plastic enters the nozzle tips, and at last the plastic enters a plurality of mould cavities.
Description
Technical field
The utility model relates to carrying receiving chews sharp TOP-TIP more, relates in particular to receive for carrying of little plastic product to chew sharp TOP-TIP more.
Background technology
The injection mold TOP-TIP is the developing direction of Injection Industry, with respect to cold runner, has and economizes in raw materials, and boosts productivity, and improves product quality, simplifies the plurality of advantages such as product following process.And in large injection mold, TOP-TIP has become its requisite important component part, because only have the employing hot flow path, could effectively reduce the pressure loss, make the shaping of product more smooth and easy, product quality is higher or allow effectively moulding in the situation that common Shooting Technique can not moulding.
At present, the structure of the TOP-TIP of injection mold mainly is that melten gel is chewed out by the injection moulding machine gun, by the flow distribution plate shunting, is transported to each heat and chews, and arrives mold cavity again.Flow distribution plate and heat are chewed by injection molded plate and are compressed, and the lateral displacement of flow distribution plate allows flow distribution plate and heat chew the state of being adjacent to that is in all the time again when guaranteeing both can allow thermal expansion between flow distribution plate and hot the chewing, and is unlikely to leak glue
Although TOP-TIP has above-mentioned plurality of advantages, also there is certain deficiency in it.It is as follows with shortcoming that it is not enough: (1) therefore can't carry out the shunting operation because the hot runner manifold in the existing hot runner mould only has one deck; (2) owing to generally only have a hot mouth in the existing hot runner mould, because the quantity of hot mouth very little, restricted the further raising of production efficient.
Because said structure leaks easily glue and mounting or dismounting inconvenience in injection mold, and every mounting or dismounting once will increase again the possibility of leaking glue because of wearing and tearing or rigging error.It is chewed heat directly and is locked on the runner plate with thread, needle-valve drives cylinder, heat is chewed adopts whole assembling with runner plate, like this processing request of client's injection molded plate greatly reduced, as long as the client processes the size that heat is chewed sealing glue position, but but there is following technical barrier in this structure, be exactly that flow distribution plate can drive heat and chews together lateral expansion, namely whole TOP-TIP heat is chewed and easily become crooked in expansion, thereby heat is chewed material needs specific (special) requirements.Be exactly that this infrastructure cost is higher in addition, so generally the first structure than traditional is expensive more than 20% for selling price.
More corresponding less plastic cement products, its mould generally adopts multi-point mould, and general hot flow path is because the heat of itself is chewed the injection moulding requirement that the restriction of size can't be satisfied mould at all.
Summary of the invention
For defects of the prior art, the utility model provides to receive chews sharp TOP-TIP more, described system comprise flow distribution plate, main penetrate chew, sliding shim, center pad, centrepin, stop pin, Re Zui; Wherein said master penetrates and chews the top that is arranged on flow distribution plate, plastic material is penetrated to chew by the master by injection machine and is entered described flow distribution plate, having described centrepin corresponding to the main bottom of penetrating the flow distribution plate of chewing, described center pad is set between described centrepin and the described flow distribution plate; Top at described flow distribution plate arranges sliding shim, has described heat in the bottom of described flow distribution plate and chews, and the end that described heat is chewed is connected with described flow distribution plate by flange, and the other end that described heat is chewed has a plurality of gum outlets; Wherein in described flow distribution plate, arrange the sprue of plastic material, one end of described sprue is penetrated to chew with described master and is communicated with, the other end of described sprue is connected with a plurality of runners that are arranged in described heat and chew layout, described a plurality of runner is chewed the gum outlet place and is all had the point of chewing being positioned at described heat, chews sharp spacing and is not less than 10mm.
Preferably, chew wall in described heat and be wound with heater strip, and described flange is Split flange.
Preferably, the place is furnished with pressure cap at described runner gum outlet, chews point and closely cooperates by described pressure cap and runner.
Preferably, described flow distribution plate is provided with heater strip, so that the injected plastics material of flow distribution plate inside is in molten condition.
Flow distribution plate is fixed in the runner plate, and there is the heater strip that heat can be provided its inside, and can make the plastic cement in the flow distribution plate runner be in a weighing apparatus temperature state always.Sliding shim cooperates and pushes down flow distribution plate in pad on the flow distribution plate and the template, prevents that flow distribution plate from chewing the runner joint leaks glue because of the gap problem with hot.It is identical with flow distribution plate runner hole that heat is chewed the runner hole, to guarantee runner inside without the dead angle, also can not produce owing to the different problems that the pressure loss occurs of runner hole size.Heat is chewed flange and is chewed the precision-fit that fixed head carries out small size with heat, can chew to heat on the one hand to position the least possible being lost on the template of heat that the simultaneously contact of small size can make heat chew.For the heat that is delivered to of the maximum temperature limit of heater is chewed inside, adopted heater strip to be wrapped in heat and chewed mode on the body: 1. heat is chewed body and is adopted high-accuracy two-axle interlocking Digit Control Machine Tool processing heater strip groove, and before the heater strip of arranging, calculate the thermal balance that whole heat is chewed by hot analysis mode; 2. heater strip is chewed three of bodies with heat and is contacted, and has improved the efficient of hot transmission, has reduced heat loss, has saved power cost; 3. heater strip is wrapped in mode that heat chews and has also reduced mould and open frame, has made things convenient for processing.Heat is chewed inside and is offered many runners, runner is shunted by flange, finally docks with the aperture with chewing point, has realized that plastics enter main penetrating by injection machine gun barrel and chew, enter flow distribution plate again and shunt and enter Re Zui, heat is chewed to shunt to enter again and is respectively chewed point and finally enter a plurality of mold cavities.
