The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1 and Figure 5, this mould ingate and runner pickoff, comprise framed (in figure, not marking), core rod, angle ejector rod 40, with push rod fixed head 50, on core rod sidewall, offer into solation road 22, it is characterized in that, upright guide rail 30 is installed on framed, described core rod comprise up and down against upper mold core 10 and lower mold core 20, upper mold core 10 sidewalls are positioned at upright guide rail 30 and upper mold core 10 only can move up and down along upright guide rail 30, angle ejector rod 40 one end tilt to be connected with lower mold core 20, the other end passes push rod fixed head 50 and can in push rod fixed head 50, radially slide, on push rod fixed head 50, be fixed with push rod 60 always, straight push rod 60 one end are fixed with the first slide block 61, lower mold core 20 lower surfaces have the first chute 62, the first above-mentioned slide block 61 is positioned at the first chute 62 and enters solation road 22 through the first slide block 61 sidewalls.
Upwards promote angle ejector rod 40, because angle ejector rod 40 is obliquely installed, so being subject to the power that angle ejector rod 40 applies, lower mold core 20 is divided into the power in power and horizontal direction straight up, because upper mold core 10 is positioned at upright guide rail 30, upper mold core 10 can only move upward along upright guide rail 30, can move in the horizontal direction so lower mold core 20 is subject to the power that power that angle ejector rod 40 applies is divided in power and horizontal direction straight up on vertical direction.Starting stage, be positioned at the first slide block 61 owing to entering solation road 22 parts, the first slide block 61 of straight push rod 60 ends moves down relatively, be positioned at entering solation road 22 and can relatively move down on slide block, thereby the residue colloid entering in solation road 22 just can be pulled down the loosening convenient cast gate of further removing after a while.Lower mold core 20 moves horizontally, in movement, the colloid and the shaped article that are positioned at cast gate on core rod and runner are disconnected, thereby play the effect of removing colloid in cast gate and runner, now angle ejector rod 40 also moves radially in rising in push rod fixed head 50, thereby the stable firmly direction of motion of angle ejector rod 40, assurance angle ejector rod 40 can not be vacillated now to the left, now to the right.
As shown in Figure 2, upper mold core 10 lower surfaces are inclined-plane, lower mold core 20 upper surfaces are inclined-plane, two inclined-planes cooperation complementations and incline direction are identical with angle ejector rod 40 incline directions, upper mold core 10 lower surfaces have two second chutes 12, in chute, be provided with the second slide block 11, lower mold core 20 and the second slide block 11 are connected, the second slide block 11 engages tighter with the second chute 12, guarantee that in the time of formed product or under inactive state upper mold core 10 and lower mold core 20 can relative slidings, when in the time that upper mold core 10 and lower mold core 20 move up simultaneously, upper mold core 10 can only be moved up by upright slide rail constraint, even and if thereby the smaller lower mold core 20 of component in the horizontal direction adipping of taking advantage of a situation moves and reaches the object that disconnects colloid in cast gate and runner.
Lower mold core 20 two ends, upper surface offer two recesses 21, upper mold core 10 end corresponding with recess 21 is provided with block 13, after lower mold core 20 starts to move along upper mold core 10 lower surfaces, the recess 21 of lower mold core 20 moves into block 13 belows, when lower mold core 20 continues mobile, recess 21 sidewalls contact with block 13, and lower mold core 20 can not continue to move horizontally, and have controlled the scope that lower mold core 20 moves.
Preferably, the number of angle ejector rod 40 is two and be arranged in parallel, two angle ejector rods 40 act in lower mold core 20 simultaneously and can make lower mold core 20 stressed evenly, lower mold core 20 is milder in the process of rising or translation, angle ejector rod 40 is 75 ° with the acute angle angle of lower mold core 20, guarantee that the thrust that lower mold core 20 is subject to is upwards greater than the thrust being subject in horizontal direction, thereby it is slower that lower mold core 20 is moved horizontally, can guarantee that colloid in cast gate and runner reasonably removes and there will not be the phenomenons such as very lofty fracture.
As shown in Figure 3, the first slide block 61 lower end horizontal directions have protrudes 63, preferably, the direction of protrusion 63 is vertical with the direction of the first chute 62, the first chute 62 madial walls offer groove 64, the direction of groove 64 is in like manner also vertical with the direction of the second chute 12, above-mentioned protrusion 63 is positioned at groove 64, when original state, lower mold core 20 is stopped by the protrusion 63 on the first slide block 61, cannot horizontal slip, when lower mold core 20 is upwards ejected after a segment distance by angle ejector rod 40, groove 64 is positioned at while protruding 63 upper end, lower mold core 20 just can move horizontally, such structure guarantees that lower mold core 20 does not have any movement when we cast product.
As shown in Figure 4, on push rod fixed head 50, offering rectangle chute 51 and angle ejector rod 40 is projected on chute axial line, angle ejector rod 40 is through rectangle chute 51, angle ejector rod 40 upwards promotes lower mold core 20, thereby lower mold core 20 horizontal directions move the colloid of removing in cast gate and runner, in the time recovering the position of lower mold core 20 and angle ejector rod 40, angle ejector rod 40 can be more convenient in the interior movement of rectangle chute 51.
The utility model discloses a kind of mould ingate and runner pickoff, be divided into upper mold core 10 and lower mold core 20 by core rod, then the method for mobile lower mold core 20 is removed the colloid in cast gate and runner, and simple and practical, efficiency is high.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
