Abstract
The utility model discloses a kind of ejection device utilizing slide block, comprise shovel base, slide block and connect the Angle Pin shoveling base and slide block, a jacking block and pressing plate is provided with in described slide block, pressing plate is stated by spring top residence in one end of described jacking block, is provided with a slot in described slide block, and described slot is mutually vertical with described jacking block, position-limited needle is provided with in described slot, described jacking block is provided with a chute, and described position-limited needle one end is screwed in described slot, and its other end is inserted in described chute.The utility model has the advantage of: by being provided with slide block, being located at slide block upper hopper chute and position-limited needle, can open time be saved; Ensure the Forming Quality of product when die sinking and mold-closing injection.
Description
Technical field
The utility model relates to mould applications, in particular to a kind of ejection device utilizing slide block.
Background technology
The slide block of mould arranges push pin device and applies very extensive, when product needed slide block mechanism is shaping, on slide block during the complex-shaped parcel slide block in product position, like this when slide block moves because the parcel power of product, product will stick on slide block, follows slide block movement and product can be made like this to produce be out of shape, pulls, rupture, in order to head it off, slide block adds jacking block, and when slide block moves, product can keep motionless relatively, so they are steadily separated.
Be in the Chinese patent of " 201220124824.6 " at application number, disclose the utility model of a section " slider ejection mechanism " by name, this utility model discloses a kind of slider ejection mechanism, comprise the slide block coordinated with oblique guide pillar, in slide block, thimble is set, thimble is set with the spring will pushed away before thimble.When this utility model can solve die sinking, product sticks the problem on mould slide block, but, spring is by the time needed to recover former length completely, follow slide block to continue to shrink back, thimble just can depart from product, and open time is slightly long, be unfavorable for the raising of production efficiency, in addition when injection moulding, thimble because of the reason of spring outstanding and easily because injection pressure is reversed, affect formed product in die cavity.
Summary of the invention
The utility model aims to provide a kind of ejection device utilizing slide block, to solve the problem.
A kind of ejection device utilizing slide block, comprise shovel base, slide block and connect the Angle Pin shoveling base and slide block, a jacking block and pressing plate is provided with in described slide block, pressing plate is stated by spring top residence in one end of described jacking block, is provided with a slot in described slide block, and described slot is mutually vertical with described jacking block, position-limited needle is provided with in described slot, described jacking block is provided with a chute, and described position-limited needle one end is screwed in described slot, and its other end is inserted in described chute.
Further, the length of described chute is greater than the diameter of described position-limited needle.
The utility model has the advantage of: by being provided with position-limited needle and chute, the displacement of slide block can be limited, can not retreat because of injection pressure during injection moulding, affect formed product, can not because withstanding product always during die sinking, make that ram travel is elongated could take out product, can save time, raise the efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Structural representation when Fig. 1 is the utility model matched moulds;
Structural representation when Fig. 2 is the utility model die sinking.
Detailed description of the invention
In order to solve slide block under the action of the spring, cause open time slightly length be unfavorable for that production efficiency improves, during injection moulding simultaneously, slide block is outstanding in die cavity, easy to shrink back because of injection pressure thus affects the problem of forming quality of products, now provides a kind of ejection device utilizing slide block.
Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technical scheme in the utility model, obviously, described is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all belongs to the scope of the utility model protection.
As Fig. 1, shown in 2, a kind of ejection device utilizing slide block, comprise shovel base 6, slide block 1, and connect the Angle Pin 7 of shovel base 6 and slide block 3, jacking block 3 and a pressing plate is provided with in described slide block 1, described pressing plate 5 is withstood by spring 4 in one end of described jacking block 3, it is characterized in that, a slot is provided with in described slide block 1, described slot is mutually vertical with described jacking block 3, position-limited needle 2 is provided with in described slot, described jacking block 3 is provided with a chute 9, described position-limited needle 2 one end is fixed in described slot by screw 8, its other end is inserted in described chute 9, the length of described chute 9 is greater than the diameter of described position-limited needle 2, concrete length is shown actual demand and determines.
During die sinking, shovel base 6 moves up, and slide block 1 retreats, and the position that jacking block 3 keeps original because of the effect of spring 4 is motionless to withstand product, product is separated with slide block 1, when slide block 1 retreats to certain distance, due to the position-limiting action to jacking block 3 of position-limited needle 2, jacking block 3 together can shrink back with slide block 1, do not need by the time spring 4 to recover former length completely to follow slide block 1 and continue to shrink back and just can depart from product, save time, when jacking block 3 no longer withstands after product die sinking completes, desirable go out product; During injection moulding, due to the position-limiting action of position-limited needle 2 pairs of jacking blocks 3, jacking block 3 additionally can not to project in die cavity and can not affect the Forming Quality of product because the pressure of injection moulding shrinks back.
Described in above, advantage of the present utility model has: by being provided with slide block, being located at slide block upper hopper chute and position-limited needle, can save open time; Ensure the Forming Quality of product when die sinking and mold-closing injection.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
