Abstract
The utility model discloses a plastic mould. The plastic mould comprises an upper mould core, a lower mould core and a parting surface, wherein the parting line is arranged between the upper mould core and the lower mould core, a sealing compound position is arranged below the parting surface, and one end of the parting surface is provided with an inserting face. Due to the fact that the parting surface is changed to an inserting sealing compound, the obtained product outside surface can be high in quality, meet requirements of a client, reduce follow-up manufacturing procedure of the products, and shorten delivery time of the products.
Description
Technical field
The utility model relates to a kind of plastic mould, belongs to mould manufacturing field.
Background technology
In the Design of Plastic Mould; we usually have such idea; can do and bump the place of wearing and do not do to insert and wear; even can try every possible means and change into bumping and wear inserting the place wear; this mainly is to consider problem die life; be through in the process of continuous die sinking matched moulds because insert, frictional heat causes the slotting position of wearing to burn out easily; burn; need in most situation to avoid so insert to wear, and for the product of surface lacquer, its surface requirements is very high; this just needs the more requirement of considering Surface Appearance; because bump wear overlap trend along die joint, perpendicular to product surface, clearly concave-convex sense after wiping out; and slotting trend of wearing overlap is the surface along product; connect so relatively fairing, wipe out afterwards on not impact of appearance, therefore change to bump for surface lacquer product die joint and wear that to wear be significant in order to insert.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is, a kind of plastic mould is provided, and obtains the more good product of surface quality by die joint being changed into slotting Chuanfeng's glue, thereby satisfy client's requirement, equally also reduce unnecessary subsequent treatment after the formed product.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of plastic mould, comprise that upper cores, counterdie Renhe be located at the die joint between the upper and lower die, it is characterized in that: described die joint below is provided with the sealing position, and described die joint one end is provided with one and inserts face.
Aforesaid a kind of plastic mould is characterized in that: described slotting face forms a circular arc along the direction of die joint and with die joint.
Aforesaid a kind of plastic mould is characterized in that: the described sealing distance of positions separates profile 5～10mm.
The beneficial effects of the utility model are: die joint is changed into insert Chuanfeng's glue, the appearance of the product of acquisition is of high quality, and satisfies client's requirement, has reduced product following process operation, has shortened the friendship phase of product.
Description of drawings
Fig. 1 is that die joint is to bump the structural representation of wearing;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
For further disclosing the technical solution of the utility model, describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: as shown in Figure 2, a kind of plastic mould, comprise upper cores 1, lower die 2 and be located at die joint 3 between the upper and lower die, die joint 3 belows are provided with sealing position 4, and sealing position 4 is 5～10mm to the distance of die joint 3.Die joint 3 one ends are provided with one and insert face 5, insert face 5 and form a circular arc along the direction of die joint 3 and with die joint 3.
Fig. 1 is that the product die joint is to bump the structural representation of wearing, the burr direction that produces as shown by arrows, after burr are removed, product surface has obvious concave-convex sense, changes into after the face of inserting, as shown in Figure 2, the burr of product are along product surface, be connected very fairing with product surface, after burr are removed like this, can be not influential to product surface.
Manufacture method: die joint is carried out sealing, the prosposition of then going further along product external surfaces toward downward-extension 5～10mm.Because Surface Appearance generally all has gradient, the also position of die folding up and down just herein, when the filling plastic mold cavity, under the crunch effect of injection moulding, overlap is inevitable to be overflowed along the sealing position of this 5～10mm, and sealing position and Surface Appearance be along connecing, like this overlap also with Surface Appearance along connecing, follow-up wipe out the overlap very convenient.
Because the die joint of the product that changes, changed it into slotting wearing, in the continuous moving process of mould, this position also is constantly in friction loss, be easy to cause the problem of precision herein, therefore consider from structure aspects, can do herein a slotting mold insert of wearing, after producing such situation, it is just passable only to need to change mold insert, although many processing charges of such mold insert, the product appearance that forms out by the utilization that facts have proved this structure is zingy, is far superior to bump wear the product that die joint forms out.
More than by description of listed embodiment, basic conception of the present utility model and basic principle have been set forth.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of change of doing based on the technical solution of the utility model all should belong to protection domain of the present utility model.
Claims (3)
