Abstract
The invention relates to an angle pin mechanism for a mold. The angle pin mechanism for the mold comprises an ejector pin and an insert which is connected to one end of the ejector pin, wherein an insert guide block is arranged on the side surface of the insert; one end of the insert guide block is provided with a slope; the other end of the insert guide block is provided with a connecting rod; the connecting rod is fixed to a lower mold core; and the slope is provided with a T groove and an insert needle which is in sliding connection with the T groove. According to the angle pin mechanism for the mold, by fixing the insert at the front end of the ejector pin, arranging the insert guide block and the insert needle on the insert and limiting the motion trajectory of the insert needle through the T groove in the insert guide block, linear movement of the ejector pin is converted to inclined hole extraction of the insert needle during mold opening. The angle pin mechanism for the mold has a simple structure, saves the mold opening time, is reasonable in design and is suitable for large-scale popularization.
Description
Technical field
The present invention relates to mould applications, especially design the Slanting pin mechanism of a kind of mould.
Background technology
Taper pin is one of mechanism of mould, needs first to divide product structure before Design of Dies
Analysis.When there is barb on product structure, it is generally required to introduce Slanting pin mechanism.But it is existing
The big mould having can not separate by three templates and take out inclined hole.
Summary of the invention
For the present situation of above-mentioned prior art, the technical problem to be solved is to provide
One can carry out taking out inclined hole for big mould, simplifies the Slanting pin mechanism of mould structure.
The present invention solves the technical scheme that the problems referred to above are used: the taper pin machine of a kind of mould
Structure, including thimble, also includes the insert being connected to thimble one end, and this insert side is provided with pin
Guide pad, described pin guide pad one end is provided with the domatic other end and is provided with connecting rod, and described connecting rod is solid
Due to lower die, the described domatic T of being provided with groove and the pin being slidably connected with T groove.
Further, being provided with spring between described insert and lower die, spring is located at by described thimble
Center, it is simple to during die sinking, guides insert.
Further, described insert is provided with the U groove coordinated with pin guide pad, it is simple to dismounting
Pin guide pad.
Further, described pin one end is provided with countersunk head.
Compared with prior art, it is an advantage of the current invention that: the present invention uses solid in thimble front end
Determine insert, and pin guide pad and pin are set in insert, by the T on pin guide pad
Groove limits the movement locus of pin, it is achieved when die sinking, the rectilinear movement of thimble changes into pin
Inclined hole extract out, this simple in construction, save the die sinking used time, the present invention is reasonable in design, is suitable for big
Scale is promoted.
Accompanying drawing explanation
Fig. 1 is the Slanting pin mechanism of a kind of mould of present invention structural representation in mould；
Fig. 2 is the three-dimensional exploded view of the Slanting pin mechanism of a kind of mould of the present invention；
Fig. 3 is the structural representation of the insert of a kind of mould of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention
It is clearly and completely described, it is clear that described embodiment is only a present invention part
Embodiment rather than whole embodiments.Based in the present invention being embodiment, this area is general
The every other embodiment that logical technical staff is obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
As shown in Figure 1-2, the Slanting pin mechanism of a kind of mould, including thimble 3, also include connecting
In the insert 2 of thimble 3 one end, by the screw thread of this thimble 3 end and the screw in insert 2
Connection is relatively fixed, and is provided with spring 6, described thimble 3 between described insert 2 and lower die 7
Being located at spring 6 center, it is simple to during die sinking, the movement to insert 2 guides；This insert 2
Side is provided with pin guide pad 4, and described insert 2 is provided with the U coordinated with pin guide pad 4
Groove 21；It is provided with the domatic other end in described pin guide pad 4 one end and is provided with connecting rod 5, this pin
Guide pad 4 is threaded connection with connecting rod 5, by under threaded for connecting rod 5 other end being fixed on
Die 7, described domatic on be provided with T groove and the pin 1 being slidably connected with T groove, described edge
Pin 1 one end is provided with countersunk head, so that pin 1 can slide by pin guide pad 4 relatively.
During mold, ejector retainner plate 8 drives thimble 3 upwards to eject, by spring 6 to insert 2
Motion guides, insert 2 drive pin 1 to move in the T groove of insert guide pad 4,
Pin 1 is internal mobile to insert 2, until abjection glue position smoothly.
During reset, drive the downward return of thimble 3 by ejector retainner plate 8, drive insert 2 and pin
1 moves, and pin 1 moves in the T groove of insert guide pad 4, until having resetted.
Compared with prior art, it is an advantage of the current invention that: the present invention uses in thimble 3 front end
Fixing insert 2, and pin guide pad 4 and pin 1 are set in insert 2, by pin 1
T groove on guide pad limits the movement locus of pin 1, it is achieved when die sinking, thimble 3 straight
Line moves the inclined hole extraction changing into pin 1, this simple in construction, saves the die sinking used time, this
Bright reasonable in design, it is suitable for large-scale promotion.
Last it is noted that above example is only in order to illustrate technical scheme, and
Non-to its restriction；Although the present invention being described in detail with reference to previous embodiment, ability
Territory it will be appreciated by the skilled person that it still can be to the technical side described in foregoing embodiments
Case is modified, or replaces wherein portion of techniques feature on an equal basis；And these amendment or
Person replaces, and does not make the essence of appropriate technical solution depart from various embodiments of the present invention technical scheme
Spirit and scope.
