Abstract

Disclosed is a plastic mould which comprises an upper mould, a lower mould and a slide arranged between the upper mould and the lower mould; the plastic mould is characterized in that a guide column is arranged on the plastic mould; the upper end of the guide column is fixed on the upper mould; the guide column is composed of an upper part and a lower part which are provided with angles; wherein, an inclined hole is arranged on the slide; the guide column of the upper mould used for delaying the opening of the slide is inserted into the inclined hole. The plastic mould has the advantages that firstly, the slide is enabled to be delayed in demould compared with the upper mould through the delay structure of the guide column, facilitating the demould of the plastic products which have complicated shapes and large areas of the upper mould plastic products and less lower moulds; secondly, the structure is simple and the machining and manufacturing are convenient; thirdly, the plastic mould has long service life.

Description

A kind of plastic mould

[technical field]

The utility model relates to a kind of plastic mould, relates to the row position fixed structure of mould in particular.

[background technology]

Existing plastic mould generally all includes upper die and lower die and row position, and the row position is arranged between patrix and the counterdie, mainly is the moulding that is used for the plasthetics side, such as screw hole etc.When die sinking, same moved further is carried out with upper and lower mould often in the row position.The plasthetics die sinking that this structure is used for simple structure still can, complex-shaped when the patrix plasthetics, area is big and counterdie relatively more after a little while, when die sinking, just make the bonding patrix of goods easily, cause the bad moulding of the demoulding.

[utility model content]

Therefore, the purpose of this utility model is to have solved the bad problem of the demoulding that capable position and the synchronous die sinking of patrix are brought, and a kind of plastic mould of going a delaying mould-release is provided.

For achieving the above object, the utility model by the following technical solutions:

A kind of plastic mould includes patrix, counterdie, and the row position, described row position is characterized in that also being provided with a guide pillar between upper die and lower die, and the upper end of described guide pillar is fixed on the patrix, and described guide pillar is to be made of the upper and lower two parts with an angle; The position of wherein being expert at is provided with inclined hole, and the guide pillar on the described patrix can postpone being plugged in the inclined hole of row position die sinking.

The big I of inclined hole vertically moves in inclined hole for guide pillar top as mentioned above, and the row position is stirred to a side displacement by the guide pillar bottom when moving in described guide pillar bottom in inclined hole.

Aforesaid a kind of plastic mould, the top that it is characterized in that described guide pillar is for vertically being provided with, and the bottom of described guide pillar is to lopsidedness.

Aforesaid a kind of plastic mould is characterized in that described guide pillar is a square column.

Aforesaid a kind of plastic mould is characterized in that the outside of described row position is provided with locating part.

Aforesaid a kind of plastic mould is characterized in that being provided with back-moving spring between counterdie and row position.

The utility model has the advantages that: 1, described row position enough postpones in last moulding/demoulding capable potential energy by the delay structure of guide pillar, is convenient to that the patrix plasthetics is complex-shaped, area is big and the less relatively plasthetics die sinking of counterdie.2, simple in structure, be convenient to processing and manufacturing.3, long service life.

[specific embodiment]

Below in conjunction with accompanying drawing the utility model is done detailed explanation

As shown in Figure 1, a kind of plastic mould of the utility model includes patrix 1, counterdie 2, row position 3, described row position 3 is between patrix 1 and counterdie 2, also be provided with a guide pillar 4, the upper end of described guide pillar 4 is fixed on the patrix 1, and described guide pillar 4 is to be made of the upper and lower two

parts

5,6 with an angle.The position of wherein being expert at 3 is provided with inclined hole 7, and the guide pillar 4 on the described patrix 1 is plugged in the inclined hole 7.

The big I of inclined hole 7 described in the utility model vertically moves inclined hole 7 in for guide pillar top 5, and described guide pillar bottom 6 is when moving inclined hole 7 in, is stirred by guide pillar bottom 6 and goes 3 to a side displacement.

In the present embodiment, be vertically to be provided with the top 5 of described guide pillar 4, the bottom 6 of described guide pillar 4 is to lopsidedness.Described guide pillar 4 is a square column.

The utility model is provided with locating part 8 in the outside of described row position 3, and described locating part 8 stops row position 3 further to be moved laterally, and is provided with back-moving spring 9 between counterdie 2 and row position 3, guarantees safety.

The utility model in use, 3 the upper and lower both sides, position of can being expert at add wearing plate, the service life of lengthening row position.The utility model is when die sinking, described patrix 1 begins earlier to move upward, this moment, guide pillar top 5 motion of being expert in the inclined hole 7 of position 3 was unaffected, plasthetics is subjected to the restriction of row position 3, make plasthetics break away from patrix 1 fully, in the time of in guide pillar bottom 5 enters inclined hole 7, cooperate inclined hole 7 to stir row position 3 by the guide pillar bottom again and break away from plasthetics, thereby reach the effect that postpones row position 3 die sinkings from a side.Therefore be convenient to that the patrix plasthetics is complex-shaped, area is big and the less relatively plasthetics die sinking of counterdie.
