Service life.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the mold of fine positioning of the utility model；
Fig. 2 is the schematic diagram of one specific embodiment of the utility model；
Reference numeral is as follows：
1, upper mold, 2, lower die, 3, positioning device, the 31, first locating piece, the 32, second locating piece, 33, third locating piece,
34, separate column.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only explaining this reality
With novel, it is not used to limit the utility model.
A kind of mold of fine positioning of the utility model, including upper mold 1 and lower die 2, upper mold 1 are fastened in lower die 2,
In, further include at least one set of positioning device 3, positioning device includes the first locating piece 31, the second locating piece 32, third locating piece 33
With separation column 34, the lower surface of the first locating piece 31 and the second locating piece 32 insertion upper mold 1, and the first locating piece 31 and second
The lower surface of locating piece 31 is less than the lower surface of upper mold 1, separate the setting of column 34 the first locating piece 31 and the second locating piece 32 it
Between, the groove for housing third locating piece 33 is formed, third locating piece 33 is embedded in the upper surface of lower die 2, in molding, third
Locating piece 33 is between the first locating piece 31 and the second locating piece 32, and the two side of third locating piece 33 and the first positioning
The side wall of block 31 and the second locating piece 32 fits closely.
In one embodiment, as shown in Fig. 2, positioning device 3 is provided with two groups, adjacent the two of mold are separately positioned on
Side can carry out fine positioning, of course, it is possible to pass through increase by the restriction to die length direction and width direction to mold
The quantity of positioning device 3 increases the positioning intensity and positioning accuracy of mold.
In one embodiment, the first locating piece 31 and the second locating piece 32 are removably connect with upper mold 1, and third is fixed
Position block 33 is removably connect with lower die 2, since the upper mold 1 and lower die 2 of mold are constantly molded and molded, first can be caused to determine
It rubs between position block 31,33 contact surface of the second locating piece 32 and third locating piece, in the course of time, shadow can be caused to fine positioning
It rings, so, the first locating piece 31, the second locating piece 32 and third locating piece 3 removably connect, convenient subsequently to replace, and make mould
Tool remains that certain precision, nothing need to change whole set of die；Preferably, in order to facilitate the replacement of locating piece, the first locating piece
31 and second locating piece 32 be screwed in upper mold 1, third locating piece 33 is screwed in lower die 2.
In one embodiment, separate column 34 to be wholely set with upper mold 1, separate and form groove between column 34 and upper mold 1,
It is limited for the side wall to the first locating piece 31 and the second locating piece 32, makes it in use will not occurred level position
It moves, causes the error in positioning.
In one embodiment, the first locating piece 31, the second locating piece 32 and 33 contact surface of third locating piece are provided with
Lead angle, when mold is in molding, third 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 influenced third 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 third locating piece 33 can be made to be damaged, lead angle is set, it is possible to reduce first is fixed
It expands and damages between position block 31, the second locating piece 32 and third locating piece 33, while keeping mold clamping smooth.
