Through in the pilot hole 26 in push pedal 20, and guide 60 is mutually perpendicular to pilot hole 26.In this way, lead in present embodiment
Crossing 4 guides 60 can carry out spacing to the direction of motion of push pedal 20, make push pedal 20 can only be along the direction of guide 60（The
Two directions）Moved.
Because angled-lift splits can only follow tie-beam to be moved in a first direction, and push pedal can only be along guide
Moved on two directions, skewed slot and locating part be set in push pedal by being set on angled-lift splits, by limited post in skewed slot phase
The first direction conversion of motion of angled-lift splits can be moved for the second direction of push pedal to sliding, needle is fixed in push pedal, can
The motion of push pedal is followed to realize being turned on and off for cast gate in TOP-TIP.
Join Fig. 8 and with reference to shown in Fig. 1 ~ Fig. 7, the type of drive of needle drive system is specific as follows in present embodiment：
When the level of 10 drive connection beam of dynamical system 40 is to left movement, locating part 23 can be along skewed slot 51 from opening to closing
Locate relative motion, due to the effect of guide 60, push pedal will not produce relative displacement in the horizontal direction, and from opening to envelope
The vertical position at the place of closing gradually reduces, thus locating part 23 can be moved downward along vertical direction, and then drive push pedal 20 and
Needle 30 in push pedal 20 moves straight down, using this by horizontal straight down fortune of the conversion of motion as needle to the left of angled-lift splits
It is dynamic；
When the level of 10 drive connection beam of dynamical system 40 moves right, locating part 23 can be along 51 self-enclosed place of skewed slot to opening
Locate relative motion, due to the effect of guide 60, push pedal will not produce relative displacement in the horizontal direction, and self-enclosed place is to opening
Mouthful place vertical position gradually rise, therefore locating part 23 can be moved upwards along vertical direction, and then driving push pedal 20 and
Needle 30 in push pedal 20 is moved straight up, and the level of angled-lift splits is moved right to the fortune straight up for being converted into needle with this
It is dynamic.
First direction is horizontal direction in present embodiment, and second direction is vertical direction, first direction and second direction
Angle be 90 °, in other embodiments first direction and the angle of second direction can also be 90 ° beyond angle, lead to
It is spacing to first direction progress to cross guide rail, it is spacing to second direction progress by guide, equally can be by the first of angled-lift splits
Direction conversion of motion moves for the second direction of needle.
In addition, present embodiment first direction and second direction angle are 90 °, the incline direction of skewed slot and first direction
Angle α is 30 ° ~ 60 °, and the angle β with second direction is 60 ° ~ 30 °.Preferably, the incline direction of skewed slot and first direction and the
The angle in two directions is 45 °, in this way, the ratio between move distance of horizontal direction and vertical direction is 1:1, when dynamical system drives
Tie-beam in the horizontal direction move distance S when, needle is also S in the move distance of vertical direction, passes through the driving of dynamical system
Distance can easily control the move distance of needle.
In other embodiments, the angle α of the incline direction of skewed slot and first direction, the angle β with second direction
Can not be 45 °, the move distance of the move distance of dynamical system drive connection beam in the horizontal direction and needle in vertical direction
The ratio between be cot α（Or tan β）, according to the ratio between move distance of horizontal direction and vertical direction, can be controlled by dynamical system
The move distance of needle in the vertical direction.
It should be appreciated that being illustrated in present embodiment by taking a dynamical system as an example, dynamical system passes through second
Tie-beam drives the first tie-beam of both sides to carry out horizontal movement along guide rail simultaneously, can also set in other embodiments more
Individual dynamical system, each dynamical system controls the first tie-beam to carry out horizontal movement along guide rail respectively, without setting the second connection
Beam, but need to ensure that multiple dynamical systems synchronously drive in the embodiment of multiple dynamical systems, to ensure each first tie-beam
Movement velocity, move distance it is equal, and then multiple angled-lift splitses on the first tie-beam can be synchronized with the movement, and multiple angled-lift splitses are total to
Moved with driving push pedal along guide.
In above-mentioned embodiment, angled-lift splits is installed on guide rail, angled-lift splits is driven along guide rail using a dynamical system
It is for linear motion, by skewed slot on angled-lift splits and the cooperation of push pedal, drive push pedal campaign.Push pedal limits it oblique by guide
Space in slide block movement plane, it can only be moved along guide direction, so as to realize the horizontal movement conversion of angled-lift splits
For the vertical motion of push pedal.Needle is fixed in push pedal, and the opening and closing of TOP-TIP cast gate is realized with the vertical motion of push pedal.
As can be seen from the above technical solutions, the invention has the advantages that：
Guide rail limitation tie-beam is moved in the first direction, and guide limitation push pedal is moved in a second direction, by tie-beam and
Angled-lift splits and limited post in push pedal move the first direction conversion of motion of tie-beam for the second direction of push pedal, reduce
Needle drive system space-consuming, reduces thickness, and easy to process, and installation is simple；
The angle of skewed slot is designed as needed on angled-lift splits, to control the move distance and needle of tie-beam in the first direction
In the ratio between move distance of second direction.
It should be appreciated that although the present specification is described in terms of embodiments, not each embodiment only includes one
Individual independent technical scheme, this narrating mode of specification is only that those skilled in the art will should say for clarity
For bright book as an entirety, the technical scheme in each embodiment may also be suitably combined to form those skilled in the art can
With the other embodiment of understanding.
Those listed above is a series of to be described in detail only for feasibility embodiment of the invention specifically
Bright, they simultaneously are not used to limit the scope of the invention, all equivalent implementations made without departing from skill spirit of the present invention
