Description

A kind of auto parts and components mould

Technical field

The utility model relates to injection mold field, especially relates to a kind of auto parts and components mould.

Background technology

A kind of processing method of using when injection mo(u)lding is some complex-shaped parts of batch production. Specifically refer to be heated thawingMaterial inject die cavity, after cooling curing, obtain products formed. Injection mold is a kind of instrument of producing plasthetics;Also be the instrument of giving plasthetics complete structure and accurate dimension. Injection mold is generally by dynamic model and cover half two parts groupBecome, dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine. At noteDynamic model and cover half closed formation running gate system and die cavity while penetrating moulding, when die sinking, dynamic model separates to take out plastics with cover halfProduct.

Although the structure of mould is according to plastics variety and performance, the shape of plastic products and the type of structure and injector etc.Different and ever-changing, but basic structure is consistent, mainly by running gate system, forming part, gas extraction system,Temperature control system and ejection system composition. Wherein running gate system and forming part are and the direct contact portion of plastics, and with plasticsChanging with goods, is the most complicated in mold, changes maximum, requires processing fineness and the highest part of precision; CastSystem refers to the runner section of plastics from nozzle enters die cavity, comprises sprue, cold slug well, runner and cast gate etc.Forming part refers to the various parts that form article shape, comprises dynamic model, cover half and die cavity, core, curved lever and rowGas port etc.

The auto parts and components of certain structures complexity need to adopt injection mould processing moulding, and gluing often appears in the product of mouldingMould phenomenon, is exactly briefly that product is connected closely with mould inside structure, product stripping difficulty. Existing in order to eliminate thisResemble, designer is generally provided with back-off on the mould emptier of mould, facilitates product stripping.

As shown in Figure 1, product 5 tips upside down on the notch 8 of inserting on 1 and being provided with a rectangular configuration, is positioned at and inserts 1Centering block 3 is provided with the protuberance 9 matching with notch 8, and this protuberance 9 passes and interlocks with notch 8 from 1 the side of inserting,But product 5 can only be from the vertical direction demoulding, and product 5 is subject to the restriction of centering block 3 at vertical direction, directly pull out product5, its structure can be destroyed, and therefore allows the smooth demoulding of product 5, must first protuberance 9 is separated with notch 8. ByBe arranged on and insert in 1 in centering block 3, if insert 1 certain angle that moves in the direction of the clock, can allow product 5 de-smoothlyMould, but mould inside space is extremely narrow, and not having can be for the space of 1 activity of inserting.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of auto parts and components mould, and in mould, is provided with oneMechanism can, inserting motionless in the situation that, make centering block and separation of products. This mould has ensured product stripping quality, improves intoProduct rate, has good popularizing application prospect.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of auto parts and components mould, bagDraw together the upper die and lower die that are connected with drive unit, described patrix is provided with upper cores, and described counterdie is provided with lower die,Described upper cores and lower die matched moulds form product die cavity, are provided with swing-bar mechanism, described fork in described die cavityMechanism comprises that inside is provided with the inserting of pin, pull bar, and is arranged on the centering block interior and that can rotate around pin of inserting, described inCentering block be provided with a protuberance, described protuberance passes from the sidewall of inserting, described pull bar is arranged on to be inserted interior and is positioned at pendulumThe right side of piece, described pull bar top is close to the right side wall of centering block and can be being pasted under the right side wall of centering block and slides to centering block end,Described centering block end raises into the structure that can interlock with pull bar top to the right, and described pull bar end is fixed on counterdie;

Described counterdie drives pull bar to move straight down under the effect of drive unit, and centering block is being pasted on the top of pull bar simultaneouslyUnder right side wall, slide to centering block end, and back stay top and centering block end interlock, described centering block end is in the effect of pull barLower drive centering block entirety is around pin certain angle that turns clockwise, the described protuberance retraction inside of inserting, thus reachThe object that separates with centering block of product.

Further improve as the utility model, described pull bar middle part is provided with guide pad.

Compared with prior art, the utility model has the advantage of simple in structurely, development cost is low. Specifically, counterdieUnder the effect of drive unit, drive pull bar to move straight down, the top of pull bar is being pasted under centering block right side wall and is being slided to pendulum simultaneouslyPiece end, and back stay top and centering block end interlock, centering block end drives centering block entirety around pin under the effect of pull barNail certain angle that turns clockwise, the protuberance retraction inside of inserting, thus reach the object that product separates with centering block, realShow the smooth demoulding of product, ensured the quality of product, improved yield rate.
