Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
It should be noted that, when element is called as " being fixed on " or " being arranged at " another element, it can directly on another element or may there is centering elements simultaneously.When an element is known as " being connected to " another element, it can be directly connected to another element or may there is centering elements simultaneously.
Also it should be noted that, the orientation term such as left and right, upper and lower in the utility model embodiment, is only relative concept or be reference with the normal operating condition of product each other, and should not be regarded as have restrictive.
As depicted in figs. 1 and 2, the core-pulling mechanism that the utility model embodiment provides comprises shovel 2, line position 3, Angle Pin (not shown) and ejector pin mechanism 5.Wherein, shovel 2 is arranged on front mould 1, by being bolted on front mould 1.Line position 3 coordinates with shovel 2, and line position 3 can be moved along perpendicular to die sinking direction under the effect of driving force.Angle Pin is arranged on front mould 1, and for driving when die sinking line position 3 to slide to the direction away from product 4, when matched moulds, drive line position 3 is moved near the direction of product 4.Ejector pin mechanism 5 is set in line position 3, and in the scope that die sinking distance is the first distance time, its one end is connected on product 4, and the other end is connected in shovel 2.Namely when die sinking distance is in the first distance range, line position 3 departs from product 4 under the drive of Angle Pin, and ejector pin mechanism 5 keeps motionless, product 4 can not be bonded in line position 3 and move together with line position 3.And when die sinking distance is more than the first distance, line position 3 is moved to the direction away from product 4 together with ejector pin mechanism 5, thus realize line position 3 and ejector pin mechanism 5 departs from product 4.
Further, ejector pin mechanism 5 comprises thimble 51, securing member 52 and elastic component 53.Wherein, thimble 51 is when die sinking distance is in the scope of the first distance, and its one end is connected on product 4, and the other end is connected in shovel 2.Securing member 52 fixed cover is located at thimble one end near shovel 2.Elastic component 53 is set on thimble 51, and one end is connected on securing member 52, and for flicking thimble 51 to being connected to shovel 2 near one end of shovel 2 when matched moulds, elastic component 53 is also for limiting the position of thimble 51 in line position 3.Preferably, in an embodiment of the present utility model, elastic component 53 is spring.
Further, in line position 3, offer the first through hole 31 and the second through hole 32.Wherein, first through hole 31 is for passing near one end of product 4 for thimble 51, and the second through hole 32 is communicated with the first through hole 31, and the second through hole 32 is along the expanding formation of the first through hole 31, namely the diameter of the second through hole 32 is greater than the first through hole 31, and securing member 52 and elastic component 53 are arranged in the second through hole 32.Be formed with limited step 33 in the junction of the first through hole 31 and the second through hole 32, elastic component 53 is connected on limited step 33 away from one end of securing member 52, to limit the degree of depth that thimble 51 inserts the first through hole 31.
Further, in shovel 2, the side of line position 3 is provided with the first inclined-plane 21 and the first vertical plane 22.Wherein, first inclined-plane 21 is for coordinating with line position 3, first vertical plane 22 and the first inclined-plane 21 adjoin, and for die sinking distance in the first distance range time compress thimble 51, thimble 51 is withstood on product 4 away from one end of the first vertical plane 22, prevents product 4 to be bonded in line position 3 and move together with line position 3 and be out of shape.
Further, at thimble 51, one end of shovel 2 is provided with the second inclined-plane 511 and the second vertical plane 512.Wherein, second inclined-plane 511 is for coordinating with the first inclined-plane 21 when matched moulds, and the second vertical plane 512 and the second inclined-plane 511 adjoin, and for coordinating with the first vertical plane 22, when i.e. die sinking distance is in the first distance range, the second vertical plane 512 is connected on the first vertical plane 22.
Further, one end of Angle Pin is fixedly connected on front mould 1, and in line position 3, offer the oblique gathering sill (not shown) coordinated with Angle Pin.During die sinking, Angle Pin extracts oblique gathering sill out; During matched moulds, Angle Pin inserts oblique gathering sill.
Further, above-mentioned first distance is the vertical range of the central shaft of thimble 51 and the interface point of the first inclined-plane 21 and the first vertical plane 22.The concrete numerical value of the first distance is determined according to actual conditions.
In sum, implement core-pulling mechanism of the present utility model, there is following beneficial effect: it is by sheathed ejector pin mechanism 5 in line position 3, when making die sinking distance in the first distance range, line position 3 can be slided to the direction away from product 4 and depart from product 4, and ejector pin mechanism 5 is still pressed on product 4, product 4 can not be bonded in line position 3 move together with line position 3, when die sinking distance is more than the first distance, ejector pin mechanism 5 moves to the direction away from product 4 together with line position 3, to reach the object that line position 3 and ejector pin mechanism 5 depart from product.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
