The mould has the advantages of simple and compact structure and convenient operation, and can effectively improve the demoulding production efficiency and reduce the manufacturing and using cost of the mould.
Description
Technical Field
The utility model relates to a mould, a convenient ejecting drawing of patterns mould structure specifically says so.
Background
The mould of traditional injection molding adopts hydraulic structure, ejecting to its upper mould or top molding board, lower mould or lower mould bedplate respectively, and the operating device is many, uses numerous and diverse, easily causes the mould cost high, energy resource consumption is big, the drawing of patterns inefficiency to influence high-efficient production.
Disclosure of Invention
The utility model provides a simple structure, compactness, the simple operation can effectively improve drawing of patterns production efficiency and reduce the convenient ejecting drawing of patterns mould structure that the mould made use cost.
The utility model adopts the technical proposal that: the utility model provides a convenient ejecting drawing of patterns mould structure, includes mould, lower mould, its characterized in that: four corners of the upper end surface of the lower die are respectively provided with four guide pin holes, the guide pin holes are step counter bores with small lower parts and large upper parts, four corners of the upper die are respectively connected with four guide pins in a sliding and penetrating manner, the guide pins penetrate through the lower end surface of the upper die to be step pin shaft sections with small lower parts and large upper parts, and the step pin shaft sections are matched with the guide pins and are connected in the step counter bores; a plurality of upper support pillars are uniformly distributed on the upper die in a sliding penetrating manner and staggered with the periphery of the die cavity, and the height of each upper support pillar is higher than the thickness of the upper die; a plurality of lower support pillars are uniformly distributed on the lower die in a sliding penetrating manner and staggered with the periphery of the die cavity, and the height of each lower support pillar is higher than the thickness of the lower die; the sum of the heights of the upper and lower support pillars is not less than the sum of the thickness difference of the upper and lower dies and twice the height of the die cavity; the lower die bottom end face is provided with a lower seat plate, and the lower seat plate is provided with an accommodating pin hole which is used for accommodating the lower top column in a clearance mode and does not exceed the lower end face of the lower seat plate.
Furthermore, a plurality of lifting lugs are arranged on two opposite side edges of the upper die and the lower die.
Furthermore, the upper and lower top pillars are adjacent in the same circumferential direction and at intervals.
The utility model discloses when the drawing of patterns operation, will lower the bedplate takes off, place the upper and lower mould of compound die in the press, close the pressure from top to bottom through the press, act on fore-set upper end and fore-set lower extreme down, simultaneously by last fore-set lower extreme with the lower mould down press take off, have down the fore-set upper end will go up the mould press up take off, disposable completion to the unloading of die cavity pouring product, its operation is convenient, need not other corollary equipment, drawing of patterns production efficiency is high, the mould manufacturing use cost is low.
