The specific embodiment
Below in conjunction with accompanying drawing 1 to accompanying drawing 3 and further illustrate the technical solution of the utility model 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 the thimble ejecting mechanism that is arranged at 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.When 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 separated with dynamic model supporting plate, complete ejecting for the first time of profiled member simultaneously, when 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 utility model 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 separated with breach, simultaneously under the active force of elastic slide block, also can be so that separate between movable model chamber and dynamic model supporting plate, thus complete ejecting for the first time of profiled member, facilitate 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, due to the thrust that is subject to slide block dynamic model die cavity is made progress, the thrust of thimble can not act on profiled member completely, when ejecting for the second time, because slide block slips in dynamic model die cavity and separated 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 the reset that slide block slips into 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, while is 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 utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present utility model, within these modes all will fall into protection domain of the present utility model.
