Safety position limiter 5 is additionally provided on three board molds, safety position limiter 5 includes safety signal switch and sensor block, peace
Full signal switch includes the first safety signal switch 51 and the second safety signal switch 53, and sensor block includes 52 He of the first sensor block
Second sensor block 54, wherein the first safety signal switch 51 and the cooperation induction of the first sensor block 52, for determining that shutter 4 is
No opening, if the die sinking between the first mold 1 and the second mold 2 can be carried out；Second safety signal switch 53 and the second induction
The cooperation induction of block 54, for determining whether ejector pin mechanism resets, if the conjunction between the first mold 1 and the second mold 2 can be carried out
Mould.Preferably, the first safety signal switch 51 and the second safety signal switch 53 are contact inductive switch, i.e., the first safety
Inductive signal can be just generated when signaling switch 51 touches the first sensor block 52, the second safety signal switch 53 touches the second sense
Inductive signal can just be generated by answering when block 54.
Specifically, the first safety signal switch 51 is arranged on third mold 3, and the first sensor block 52 is arranged in the second mold
On 2, the first sensor block 52 is located at the side far from the second mold 2 of the first safety signal switch 51, when third mold 3 is far from the
When two molds 2 move, third mold 3 drives the first safety signal switch 51 to move towards the first sensor block 52, when the first safety
When signaling switch 51 touches the first sensor block 52, inductive signal is issued.Specifically the setting of the first safety signal switch 51 is the
The outer surface of three molds 3, and be arranged close to the second mold 2, the induction end of the first safety signal switch 51 is located at the first safety letter
One end far from the second mold 2 of number switch 51；First sensor block 52 is arranged on the second mold 2 by induction connecting plate 55,
One end of induction connecting plate 55 is fixedly connected with the outer surface of the second mold 2, incudes connecting plate 55 towards the direction of third mold 3
Extend, one end of the first sensor block 52 is fixedly connected with induction connecting plate 55, and the other end of the first sensor block 52 extends to first
The outside of the induction end of safety signal switch 51, when third mold 3 drives the first safety signal switch 51 to be directed away from the second mould

Second adjustment hole and the second anchor structure facilitate the position for adjusting the second safety signal switch 53 on induction connecting plate 55,
And then the distance of reaction between the second safety signal switch 53 and the second sensor block 54 is adjusted, it realizes and is switched in the second safety signal
53 when sensing the second sensor block 54, and ejector pin mechanism keeps reset state, then can carry out between the first mold 1 and the second mold 2
Die closing operation.
Multiple locks 6 are additionally provided on three board molds, multiple locks 6 are distributed on each surface of three board molds, are used for
It locks between the first mold 1 and the second mold 2 or between the second mold 2 and third mold 3.
Based on above structure, the working principle of three board mold molded safeties limit control structure of the invention are as follows: with molding
State is original state, and when being opened, step 1 is opened: third mold 3 between third mold 3 and the second mold 2
It is directed away from the direction movement of the second mold 2, at this point, third mold 3 drives the first safety signal switch 51 to incude towards first
Block 52 moves, and when the first safety signal switch 51 touches the first sensor block 52, the first safety signal switch 51 issues induction
Signal, the opening and closing block on the locating part 42 of shutter 4 opens the coupler body that locking member 41 is inserted in the second mold 2 at this time, i.e., and
It is unlocked between one mold 1 and the second mold 2.During this, the second safety signal switch 53 persistently senses the second sensor block 54；
Step 2 is opened between the first mold 1 and the second mold 2: the first mold 1 is directed away from the direction movement of the second mold 2, this mistake
Cheng Zhong, the first safety signal switch 51 and the second safety signal switch 53 continue sense state；Step 3, ejector pin mechanism ejection at
Type product: ejector retainner plate 31 drives thimble to stretch out the molded surface of the second mold 2, and ejecting product, in the process, the first safety are believed
Number switch 51 keeps sense state, and the second safety signal switch 53 is not contacted with the second sensor block 54, and the second safety signal switchs
No longer issue inductive signal；Step 4, ejector pin mechanism reset, and ejector pin mechanism resets under the action of resetting-mechanism, the second safety
Signaling switch 53 is contacted again to the second sensor block 54 and issues inductive signal；Step 5, the first mold 1 and the second mold 2 it
Between molded；Step 6, after the completion of molding between the first mold 1 and the second mold 2, the second mold 2 and third mold 3 are carried out
Molding.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be in the premise for not departing from spirit of the invention
Under make a variety of changes.
