Description

Plastic mould

Technical field

The utility model relates to mould applications, particularly relates to a kind of plastic mould in order to injection molding product.

Background technology

The prior art relevant to this case can a kind of plastic mould shown in reference diagram 3, this plastic mould is in order to the rotor 60 of injection mo(u)lding one motor, it mold slide block 40 comprising a die core insert moved up and down 30 and move left and right for a pair, the position that die core insert 30 and mold slide block 40 connect is a curved surfaces, when plastic mould runs, first, die core insert 30 is moved down, this moves left and right afterwards mold slide block 40 and die core insert 30 is docking together, secondly, toward the plastic cement that die core insert 30 is melted with injection moulding on mold slide block 40, cooling forming, finally, this moves left and right away from the other side mold slide block 40, die core insert 30 moves up, exit plastic cement, rotor 60 departs from plastic mould, rotor 60 is formed with the host cavity of corresponding die core insert 30, and a pair sidewise hole of corresponding mold slide block 40, the position connected due to die core insert 30 and mold slide block 40 is set to an arcwall face 31, 41, after plastic mould repeatedly uses for a long time, die core insert 30 is not accurate with docking of mold slide block 40, both are dislocation easily, both fit clearances are excessive, cause rotor 60 madial wall forms burr, need again to process, increase the weight of production cost.

So, be necessary to improve above-mentioned technical problem.

Utility model content

The purpose of this utility model there are provided a kind ofly has the plastic mould avoiding product to occur burr.

For realizing aforementioned object, the utility model adopts following technical scheme: a kind of plastic mould, in order to injection mo(u)lding rotor, it comprises a die core insert and separates between left and right and a pair mold slide block alignd, described die core insert moves up and down with the host cavity of injection mo(u)lding rotor, described mold slide block moves left and right with the sidewise hole of injection mo(u)lding rotor both sides, sidewise hole and host cavity through, described die core insert and mold slide block have the arc interface connected, the interface of described die core insert is arranged with locating hole, described mold slide block is provided with and protrudes from interface to be plugged in the locating dowel in locating hole.

As further improvement of the utility model, described locating dowel is cylindrical.

As further improvement of the utility model, described locating dowel end has a cylindrical pilot part, and guide part front end is thin, and rear end is thick.

The interface of the die core insert of the utility model plastic mould is arranged with locating hole; described mold slide block is provided with and protrudes from interface to be plugged in the locating dowel in locating hole; the interface of die core insert and mold slide block accurately, is reliably docking together; decrease the fit clearance between die core insert and mold slide block; avoid rotor madial wall forms burr; increase the qualification rate of product, reduce production cost.

Accompanying drawing explanation

Fig. 1 is the schematic perspective view that the utility model plastic mould and rotor combine.

Fig. 2 is that the solid that the utility model plastic mould and rotor are separated is illustrated, display injection mo(u)lding completes.

Fig. 3 is the schematic perspective view that in prior art, plastic mould and rotor are separated.

Detailed description of the invention

Refer to shown in Fig. 1 to Fig. 2; the utility model plastic mould comprises a die core insert 10 and separates between left and right and a pair mold slide block 20 alignd; die core insert 10 moves down the host cavity 61 with injection mo(u)lding rotor 60; mold slide block 20 moves left and right with the sidewise hole 62 of injection mo(u)lding rotor 60 both sides, and sidewise hole 62 is mutually through with host cavity 61.

Die core insert 10 and mold slide block 20 have the arc interface 11,21 connected; the interface 11 of die core insert 10 is arranged with a circular locating openings 11; mold slide block 20 has and protrudes from interface 21 to be plugged in the circular locating dowel 22 in locating hole 11 towards moulding die core insert 10 direction; die core insert 10 accurately, is reliably docking together with the interface 11,21 of mold slide block 20; decrease the fit clearance between die core insert 10 and mold slide block 20; avoid rotor 60 madial wall forms burr; increase the qualification rate of product, reduce production cost.

Locating dowel 12 end has a cylindrical pilot part 13, and guide part 13 front end is thin, and rear end is thick, and in order to guide, locating dowel 12 is smooth-going to be inserted in locating hole 22, enters the fit clearance between a guarantee die core insert 10 and mold slide block 20.

Although be example object, disclose preferred embodiment of the present utility model, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present utility model disclosed in appending claims, various improvement, increase and replacement are possible.
