Description
Technical field
The present invention relates to a kind of mold design more particularly to a kind of high-precision processing moulds for nonstandard injection molding cyclic product
Tool.
Background technique
Shooting Technique is a kind of selection process for being able to satisfy various nonstandard shaped piece processings, cut compared to tradition,
Milling Machining operation mode is rushed, with one-pass molding, the significant advantage being produced on a large scale, however, due to the shape of injecting products
Diversity, a corresponding product generally require stand-alone development and manufacture experimently repeatedly, can put into after reaching the required precision of product
Large-scale production.However for certain complicated products, such as the special-shaped ring set of circumferential detailed structure variability, it is single
The difficulty of processing of one injection mold cavity is infinitely amplified, and die cavity is difficult to be protected to the requirement on machining accuracy in special-shaped ring set full width face
Barrier, the excess process of any one angle can all lead to that all that has been achieved is spoiled, mold is scrapped.This virtually causes very big cost wave
Take, need to propose technique improvement scheme to this, is an important technology breach that is current urgently to be resolved and promoting level of processing.
Summary of the invention
In view of the problems of the above-mentioned prior art, the purpose of the present invention is to propose to a kind of injection mold cavity of special-shaped ring set.
A kind of the purpose of the invention will be achieved through the following technical solutions: injection mold cavity of special-shaped ring set, it is described different
The front of shape ring set has groove set in circumferentially distributed several boss and boss, and the depth of groove in each boss is not
Identical to the greatest extent, the reverse side of the abnormity ring set is set as the curved surface of the irregular variation of depth, and the peripheral distribution of the abnormity ring set is equipped with
More than one locating slot, it is characterised in that: the upper cavity of the corresponding special-shaped ring set reverse side of the injection mold cavity can be integrated molding,
The matched convex chamber of shape, and the corresponding special-shaped positive lower mode cavity of ring set of the injection mold cavity is set as outside comprising corresponding special-shaped ring set
The round Reentrant Cavity of shape, corresponding boss quantity penetrate slot and activity is secured to and respectively penetrates among slot and corresponding boss and groove
The movable insert of quantity, shape.
Further, the movable insert it is separately machined molding and alternate form be secured to and penetrate among slot.
Further, the joint surface of the upper cavity and lower mode cavity, which is equipped with, is connected to the road injection mold cavity Nei Jiao and into glue
Mouthful.
Further, the Jiao Dao is set to the periphery of round Reentrant Cavity in half-surrounded, and Jiao Dao is connected outward into glue
Mouthful.
Still further, the Jiao Dao is from one end towards other end depth down, and both direction is equipped with along the Jiao Dao
The glue-feeder of injecting glue simultaneously.
Using injection mold cavity of the invention, its advantages embody conscientiously are as follows: for the circumferentially upper different unit knot of product
Structure and change in shape are arranged multiple independent movable inserts and individually process and assemble, and improve the single success rate of die trial,
Reduce the loss that injection mold cavity is integrally scrapped.
Detailed description of the invention
Fig. 1 is the structural schematic diagram at one visual angle of injection mold cavity of the present invention.
Fig. 2 is the structural schematic diagram of injection molding another visual angle of cavity shown in Fig. 1.
Specific embodiment
Just attached drawing in conjunction with the embodiments below, the embodiment of the present invention is described in further detail, so that of the invention
Technical solution is more readily understood, grasps.
As it can be seen that left side is the empty die cavity state not being molded as shown in two die cavitys of Fig. 1, right side is that product injection molding is completed
But to move back the state of mould pickup.It can be seen that the contour structures of the abnormity ring set 3 just have some idea of.Its front has circumferential point
Set groove in several boss and boss of cloth, and the depth of groove in each boss is not quite similar.Due to the abnormity ring set 3
It is not shown, thus its Facad structure combination mold cavity shapes are counter guesses as also should be clear from, and the reverse side of the abnormity ring set 3 illustrates
Compare clear, is set as the curved surface of the irregular variation of depth；And it is more than one fixed that the peripheral distribution of the abnormity ring set 3 is equipped with
Position slot (being three of three equal parts ring set in illustrated embodiment).However the labyrinth of exactly product proof, especially along ring
Covering circumferentially distributed each boss and wherein set groove has the biggish dimensions of differentiation, can not be constant by defending tenaciously
Traditional die sinking process realize accurate molding.And it is highly difficult, process resulting such die cavity in high precision and lack flexibility, work as product
After upgrading changes local parameter, original integrally formed die cavity can only scrap recasting, and to injection molding, enterprise brings huge cost
Puzzlement.
In this regard, the design inventor passes through creative work, innovation proposes a kind of injection mold cavity of special-shaped ring set.Pass through
Split-type design improves the localized design possibility of injection mold cavity, improves the recycling rate of mold.
From the point of view of specific structure feature, the upper cavity 2 of the corresponding special-shaped ring set reverse side of the injection mold cavity can be integrated molding,
The matched convex chamber of shape (Fig. 1 does not express, but is clearly understood that according to the finished form in the die cavity of right side), and injection mould
The corresponding special-shaped positive lower mode cavity 1 of ring set of chamber is set as the round Reentrant Cavity 11 comprising corresponding special-shaped ring set shape, corresponding boss number
Amount penetrate slot 12 and activity is secured to and respectively penetrates among slot and the movable insert 13 of corresponding boss and number of recesses, shape.
Each movable insert 13a ~ 13f is all loaded according to the processing request of special-shaped ring set in diagram state penetrates among slot 12, so
And the position of each movable insert and not exclusive, it is fixed selectively to be replaced according to the structural improvement of special-shaped ring set to be processed
Position.Top surface shape based on those movable inserts just forms closed injection mold cavity when being assembled into round Reentrant Cavity 11, and
After injection molding required boss with groove can be formed on special-shaped ring set.
Further refinement as above scheme is perfect, and the joint surface of above-mentioned upper cavity and lower mode cavity 11, which is equipped with, to be connected to
The road injection mold cavity Nei Jiao 4 and glue-feeder.Moreover, the glue road 4 of diagram is set to the periphery of round Reentrant Cavity simultaneously in half-surrounded
It is passed through among round Reentrant Cavity with the end Jiao Dao, and Jiao Dao connects glue-feeder outward.
It is seen as ensureing the full property into glue with refining again, above-mentioned Jiao Dao is from one end towards other end depth down (i.e. phase
It is deeper from the distant to the near to round Reentrant Cavity), the road Qie Yanjiao is equipped with the glue-feeder of both direction while injecting glue, improves for injection molding
Die cavity into glue supply amount, guarantee the structural strength of shaped article.
Using injection mold cavity of the invention, its advantages embody conscientiously are as follows: for the circumferentially upper different unit knot of product
Structure and change in shape are arranged multiple independent movable inserts and individually process and assemble, and improve the single success rate of die trial,
Reduce the loss that injection mold cavity is integrally scrapped.
Still there are many embodiment, all technical sides formed using equivalents or equivalent transformation by the present invention
Case is within the scope of the present invention.
