Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with the accompanying drawings and embodiment pair
The present invention is described in further detail.It should be appreciated that specific embodiment described herein is only to explain the present invention, and do not have to
It is of the invention in limiting.
A kind of mould of fine positioning of the present invention, including upper mould 1 and lower mould 2, upper mould 1 are fastened on lower mould 2, wherein, also
Including at least one set of positioner 3, positioner includes the first locating piece 31, the second locating piece 32, the 3rd locating piece 33 and divided
The lower surface of spacer post 34, the first locating piece 31 and the upper mould 1 of the second locating piece 32 insertion, and the first locating piece 31 and the second positioning
The lower surface of block 31 is less than the lower surface of upper mould 1, separates post 34 and is arranged between the first locating piece 31 and the second locating piece 32, shape
Into the groove for housing the 3rd locating piece 33, the upper surface of the lower mould 2 of the 3rd locating piece 33 insertion, in matched moulds, the 3rd positioning
Block 33 is between the first locating piece 31 and the second locating piece 32, and the two side of the 3rd locating piece 33 and the first locating piece 31
It is brought into close contact with the side wall of the second locating piece 32.
In one embodiment, as shown in Fig. 2 positioner 3 is provided with two groups, it is separately positioned on adjacent the two of mould
Side, by the restriction to die length direction and width, fine positioning can be carried out to mould, of course, it is possible to pass through increase
The quantity of positioner 3 increases the positioning intensity of mould and positioning precision.
In one embodiment, the first locating piece 31 and the second locating piece 32 are removably connected with upper mould 1, and the 3rd is fixed
Position block 33 is removably connected with lower mould 2, and due to the upper mould 1 of mould and lower mould 2 constantly molds and matched moulds, and first can be caused to determine
Rubbed between position block 31, the second locating piece 32 and the contact surface of the 3rd locating piece 33, in the course of time, shadow can be caused to fine positioning
Ring, so, the first locating piece 31, the second locating piece 32 and the 3rd locating piece 3 removably connect, and convenient follow-up replacing, make mould
Tool remains certain precision, without changing whole set of die；Preferably, in order to facilitate the replacing of locating piece, the first locating piece
31 and second locating piece 32 be screwed on mould 1, the 3rd locating piece 33 is screwed on lower mould 2.
In one embodiment, separate post 34 to be wholely set with upper mould 1, separate and form groove between post 34 and upper mould 1,
It is spacing for being carried out to the side wall of the first locating piece 31 and the second locating piece 32, make it in use will not occurred level position
Move, cause the error in positioning.
In one embodiment, the first locating piece 31, the second locating piece 32 and the contact surface of the 3rd locating piece 33 are provided with
Lead angle, when mould is in matched moulds, the 3rd locating piece 33 and the first locating piece 31 or the second locating piece can be made by having certain probability
32 upper surface is in contact, and is influenceed the 3rd locating piece 33 and is entered between the first locating piece 31 and the second locating piece 32, and can
The first locating piece 31, the second locating piece 32 and the 3rd locating piece 33 can be made to be damaged, lead angle is set, it is possible to reduce first is fixed
Expanded between position block 31, the second locating piece 32 and the 3rd locating piece 33 and cause to damage, while make mould matched moulds smooth.
