The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing 1 to accompanying drawing 3 and by the specific embodiment.
A kind of mould with secondary ejecting mechanism, comprise dynamic model and cover half, described dynamic model comprises dynamic model die cavity 1, the dynamic model supporting plate 2 matching with described dynamic model die cavity 1, and be arranged at the thimble ejecting mechanism of described dynamic model supporting plate 2 bottoms, described dynamic model has at least a side to be provided with secondary ejecting mechanism, described secondary ejecting mechanism comprises that one end is anchored on the push rod 3 on described thimble ejecting mechanism, described push rod 3 matches with the slide rail 4 that is fastened on described dynamic model supporting plate 2 one sides, on the sidewall of the slideway both sides of described slide rail 4, be provided with breach, described breach matches with the elastic slide block 9 that is arranged on described push rod 3 other end tops, on the sidewall of the dynamic model die cavity 1 of described elastic slide block 9 one sides, be provided with the cavity matching with described elastic slide block 9, on the sidewall of the opposite side of described elastic slide block 9, be provided with the first inclined-plane 5, on the sidewall of described breach top, be provided with the second inclined-plane 6 that slips into described cavity when described elastic slide block moves upward for pushing.In the time that push rod moves upward with thimble ejecting mechanism, the elastic slide block at push rod top also moves upward thereupon, and then dynamic model die cavity is moved upward and separate with dynamic model supporting plate, complete ejecting for the first time of profiled member simultaneously, in the time that push rod continues to move upward with thimble ejecting mechanism, the first inclined-plane on elastic slide block is subject to the extruding on the second inclined-plane of slide rail indentation, there, elastic slide block is squeezed in the cavity of dynamic model die cavity one side, the stop motion of dynamic model die cavity, thimble ejecting mechanism continues to move upward, and then completes ejecting for the second time of profiled member.The present invention is simple in structure, uses reliable and stable.
Described breach is U-lag, and described the second inclined-plane is arranged on the sidewall of described U-lag one side, and the width of described U-lag is greater than the thickness of described elastic slide block 9.The setting of U-lag, is convenient to elastic slide block and separates with breach, simultaneously under the active force of elastic slide block, also can make to separate between dynamic model die cavity and dynamic model supporting plate, thereby complete ejecting for the first time of profiled member, facilitates the demoulding of profiled member.
Described thimble ejecting mechanism comprises thimble seat 7 and the ejector retainner plate 8 that is arranged at described thimble seat 7 tops, on described thimble seat 7, is provided with thimble, and described thimble runs through described ejector retainner plate 8 and matches with the profiled member in described dynamic model die cavity 1.When carrying out first while ejecting, owing to being subject to slide block to dynamic model die cavity thrust upwards, the thrust of thimble can not act on profiled member completely, in the time ejecting for the second time, separate because slide block slips in dynamic model die cavity and with push rod, now dynamic model die cavity is subject to support the stop motion of thimble ejecting mechanism, and thimble completes the Double-ejection of profiled member, this design, has greatly reduced the bad of profiled member.
Described elastic slide block 9 comprises slide block and the spring 10 that is embedded in described slide block one side, and one end of described spring 10 and the bottom surface of described cavity are inconsistent.Being provided with of spring is beneficial to slide block slips into the reset of cavity and slide block.
One side of described cavity offers the opening connecting with described dynamic model die cavity 1 bottom surface, and described opening part is fastened with slide cover 11.
One side of described slide cover 11 is concordant with described dynamic model die cavity 1 bottom surface, and the another side of described slide cover 11 and described slide block bottom surface fit.
The width of described slide block is less than the width of described slide cover 11.The width of slide block is less than the setting of the width of slide cover, facilitate slide block can slip into completely in cavity after being squeezed, the setting of slide cover, be convenient to the processing of cavity and the assembling of slide block, simultaneously also for the round slip of slide block provides carrier, slide block is slided more smooth and easy, thereby facilitate the Double-ejection of profiled member.
Know-why of the present invention has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present invention, and can not be interpreted as by any way limiting the scope of the invention.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present invention, within these modes all will fall into protection scope of the present invention.
