Description
Technical field
The utility model relates to a kind of automobile grid material handle segmented sprue puller ejecting mechanism, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, as the automobile grid etc., because factors such as product surface requirement during injection moulding, generally adopt the submarine feeding manner.Traditional submarine feeding manner is that die cavity (cover half) side at product is opened the system charging aperture, so also can produce parting line in the product cavity side, for the product of being strict with good looking appearance is arranged, is worthless equally.So, charging aperture can only be adopted submarine open in the dynamic model of mould.After the product injection mo(u)lding, ejected outside the mould, and the material handle of product broken and stayed in the charging aperture, so need sprue puller will expect that handle ejects by the ejecting mechanism of mould.But; in actual production; many plastic products, as the automobile grid, often slide respectively the dynamic model slide block be set in the both sides of its dynamic model; so charging aperture also can only be opened in the dynamic model slide block; dynamic model slides to be needed outwards to slide, and sprue puller is connected on the top board of mould, can not move; therefore, must design a kind of sprue puller ejecting mechanism of segmented.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art; a kind of employing segmentation, dislocation design are provided; dynamic model slide block and mould die sinking action are synchronized with the movement; and the preceding paragraph sprue puller taken to and next section sprue puller concentric position, sprue puller ejects with product and ejects synchronous automobile grid material handle segmented sprue puller ejecting mechanism again.
The technical scheme of the utility model automobile grid material handle segmented sprue puller ejecting mechanism is: comprise compound plate and following compound plate on the mould; connection cover half frame under the last compound plate; fixed die insert is installed in the cover half frame; the mould pin is installed on the following compound plate; in the mould pin top board is set; connect push rod on the top board; the dynamic model frame is installed on the mould pin; moving die insert is installed in the dynamic model frame; the formed automobile grid is arranged between moving die insert and the fixed die insert; slide respectively in the both sides of dynamic model frame the dynamic model slide block is set; dynamic model slides and drives slip by the Angle Pin that is connected under the cover half frame; in the dynamic model slide block, be shaped on charging aperture; charging aperture is communicated with hot flow path; the material handle that the automobile grid is arranged in the charging aperture; it is characterized in that activity is provided with sprue puller in the described dynamic model slide block; the top of last sprue puller contacts with the material handle; the middle and lower part of last sprue puller is shaped on boss, and spacing fixed block is installed in the dynamic model slide block, and spacing fixed block is passed in the bottom of last sprue puller; and rest on the spacing fixed block by boss; be shaped on avoiding hollow groove in the dynamic model frame, the upper inner of avoiding hollow groove is shaped on the displacement groove, matches with the displacement groove in the bottom of last sprue puller; connect sprue puller down on the described top board, following sprue puller penetrates in the avoiding hollow groove.
Automobile grid material handle segmented sprue puller ejecting mechanism of the present utility model; during die sinking; move downward by injection machine power drive dynamic model frame and moving die insert; dynamic model slide block on the dynamic model frame outwards slides in the effect of Angle Pin; sprue puller displacement in the drive; the bottom of sprue puller is moved in the avoiding hollow groove from the displacement groove; be in concentric position with the following sprue puller that penetrates avoiding hollow groove; then push up on the top board, drive push rod grid is ejected outside the mould, simultaneously; top board drives down, and sprue puller Shang Ding contacts with last sprue puller; continue to go up the top again, sprue puller is ejected the material handle of grid outside the dynamic model slide block, the demoulding is finished; mould resets; sprue puller resetted under top board drove, and automatically reset under the effect of compression spring and go up sprue puller, and mould carries out next working cycles.This programme is divided into upper and lower two sections with sprue puller; upper and lower two sections sprue pullers shift to install by the displacement groove; pass through avoiding hollow groove concentric locating again, under the effect of mould open/close mould power, dynamic model slide block and mould die sinking action are synchronized with the movement again; and the preceding paragraph sprue puller taken to and next section sprue puller concentric position; sprue puller ejects with product and ejects synchronously again, and reasonable in design constitutes simple; cost is low, and product stripping is smooth.
