Embodiment 1

Fig. 1~4 are please referred to, the present embodiment discloses a kind of insert type mold core applied to preceding mould, i.e. mould before insert type Core 100, for realizing the embedded structure of preceding mould, maintenance cost and the attended operation for saving mold core are time-consuming, improve production efficiency.

Illustrate first, preceding mould and rear mold are respectively arranged on injection molding machine.Preceding mould on injection molding machine in remaining stationary, then Movement relative to preceding mould occurs for mould.It is appreciated that rear mold occurs movement relative to preceding mould and realizes when injection mold die sinking Parting.

Wherein, preceding mould generally includes front template and preceding mold core, and rear mold generally includes rear pattern plate and rear mold core.Front template installation In the stationary end of injection molding machine, preceding mold core is installed on front template.Rear pattern plate is installed on the tache motorice of injection molding machine, and rear mold core is installed on On rear pattern plate.Preceding mold core and rear the mold core mould that is involutory form required type chamber, produce to obtain in type intracavitary administration plastic cement melt Plastic cement products.

Mold core 100 is a seed type of mold core before belonging to before insert type above-mentioned.Wherein, mold core 100 includes multiple before insert type Several preceding moulds inlay chipware 110 and preceding mould supports chipware 120.It is successively end to end that a plurality of preceding moulds inlay chipware 110, To form the preceding mould embedded ring with cyclic structure.Preceding mould embedded ring one end is closed by preceding mould support chipware 120, and the other end is used Yu Yuhou mold core molds coelosis.

Wherein, adjacent preceding mould inlay chipware 110 along molding direction it is non-overlapping, avoid interfering resistance between each other Hinder, changed so that each preceding mould is inlayed chipware 110 and can independently be realized, there is the construction being independent of each other, to realize small workload Quick-replaceable maintenance.

The connection type that adjacent preceding mould is inlayed between chipware 110 is numerous, and exemplarily, adjacent preceding mould inlays chipware Chimeric surface (mould chimeric surface 114 before i.e.) between 110 is vertical surface, and the vertical surface is parallel with molding direction.Mould before it is appreciated that Chimeric surface 114 can be plane or curved surface, and keep straight along molding direction, and fluctuations do not occur.It is adjacent based on the construction Preceding mould is inlayed can freely occur opposite linear reciprocating motion along molding direction between chipware 110, to guarantee the independence of dismounting Property.

Exemplarily, any preceding mould inlays mould vertical surface 111 before chipware 110 is respectively provided with, the preceding mould vertical surface 111 and conjunction Mould direction is parallel.Wherein, preceding mould vertical surface 111 can be plane or curved surface, and keep straight along molding direction, and not occurring to rise and fall becomes Change.

Wherein, adjacent preceding mould inlay chipware 110 preceding mould vertical surface 111 it is successively end to end and modular ring shape is straight before being formed Face 130.As its name suggests, preceding modular ring shape, which faces 130 directly, has anchor ring construction, and is located at the inner peripheral surface of preceding mould embedded ring.For example, preceding Modular ring shape faces 130 directly can be for along types such as cylindrical surface, polygon cylinder, the elliptic cylinders of the extension of molding direction.

Preceding modular ring shape face 130 effect directly at least that, realize before mould it is vertical with rear mold to insert, meet injection be compressed into The application requirement of type.Particularly, in injection compression molding application, the preceding mold core 100 of insert type needs after injection with rear mold core Motion compresses type chamber, vertically to inserting frequently, front and back mold core damage situations are even more serious.Compared to existing monoblock type mold core, edge The application advantage of mold core 100 is more significant before part formula.

Exemplarily, preceding mould embedded ring and preceding mould support chipware 120 surround and form inner cavity open at one end, and preceding modular ring shape is straight Face 130 is located in the inner peripheral surface of inner cavity.It is appreciated that when current mould and rear mold mold, a part of the inner cavity structure forming cavity. Here, mold core 100 serves as base before insert type, molding is moved in inner cavity for rear mold core to slotting.

Exemplarily, preceding mould inlays chipware 110 with preceding mould positioning region 112, positions grafting for realizing with front template, with Mould inlays chipware 110 and positions/separate with the quick of front template before realizing.Wherein, the direction for positioning grafting is parallel with molding direction, To guarantee from hindering ground quick separating or being embedded in.The form of preceding mould positioning region 112 is numerous, including location hole, locating slot, fixed The types such as position boss.

Exemplarily, preceding mould positioning region 112 be located at preceding mould inlay chipware 110 close to preceding mould support chipware 120 one end, and It is dislocatedly distributed with preceding mould support chipware 120.Under the construction that is dislocatedly distributed, preceding mould positioning region 112 can directly be contacted with front template and Realize positioning grafting.

Exemplarily, preceding mould inlays chipware 110 with the preceding mould counter sink 113 for being embedded in connector.Connector is used for Mould inlays chipware 110 and front template before connection fastens, and form includes the types such as pin, bolt.Wherein, the big end opening of counter sink Yu Qianmo inlays a side surface of the chipware 110 far from front template.The big end of counter sink refers to the biggish one end in aperture, with for even The into and out counter sink of fitting.

As previously mentioned, preceding mould support chipware 120 is installed on front template, for mould embedded ring before supporting.Preceding mould supporting-core The frame mode of part 120 is numerous, and exemplarily, preceding mould support chipware 120 includes preceding mould body portion 121 and preceding mould boss portion 122. Wherein, a side surface in preceding mould boss portion 122 from preceding mould body portion 121 extends outwardly, and preceding mould body portion 121 is with before protruding from Flange flange outside 122 outer profile of mould boss portion.Correspondingly, preceding mould embedded ring is sheathed on the peripheral side of preceding mould boss portion 122 simultaneously It is connected with flange flange, realizes closing purpose.Wherein, preceding mould body portion 121 is for being installed on front template.

Exemplarily, preceding mould support chipware 120 has the preceding die hole position 123 for installing hot mouth.Hot mouth is for being connected to heat Runner and type chamber are realized and carry out melt cast to type chamber.Exemplarily, hot mouth is needle valve type hot runner hot mouth.It is appreciated that heat Runner is further fluidly connected to injection molding machine nozzle, realizes the conveying of fluid.

Embodiment 2

Fig. 5~8 are please referred to, the present embodiment discloses a kind of insert type mold core applied to rear mold, i.e. insert type rear mold Core 200, for realizing the embedded structure of rear mold, maintenance cost and the attended operation for saving mold core are time-consuming, improve production efficiency.
