Abstract
The utility model provides an injection molding die for a front supporting pad of an engine. The die comprises two or more upper dies, two or more lower dies and two or more finished product die cavities; a middle die is arranged between each upper die and each lower die; an upper plate is fixedly connected to the lower part of each upper die through a positioning pin; a lower plate is fixedly connected to the upper part of each lower die; the upper plates, the lower plates and the middle dies form the finished product die cavities; each upper die is provided with a sprue gate; a bolt is arranged in the center of each upper plate; and the sprue gates correspond to the bolts and form runner. A positioning block is arranged on each of two sides of each lower die. Plastic in a preheated forming state is injected into the die through the sprue gates, sized and vulcanized; and the die is applied to large-sized products with thick walls, thin walls and complex shapes, and is high in production efficiency and stable in quality.
Description
Technical field
The utility model relates to a kind of mould, and particularly a kind of being used for propped up the injecting molding die that fills up moulding before the engine.
Background technology
At present, processing and forming, the especially large thick-wall of a pad before the engine, thin-walled, complex-shaped goods, inefficiency, quality is unstable, and is not easy to the cleaning and the deburring of product.
Summary of the invention
The purpose of the utility model is propped up the injecting molding die that fills up moulding before providing a kind of engine; The sizing material that it will preheat completed state injects the mould first cure through the sprue gate; Be suitable for large thick-wall, thin-walled, complex-shaped goods, production efficiency is high, steady quality.
The technical scheme of the utility model: a pad injecting molding die before the engine, comprise upper die and lower die and finished product die cavity, between upper die and lower die, be provided with middle mould; Below patrix, be fixedly connected with upper plate through alignment pin; Upper fixed at counterdie has lower plate, is surrounded by upper plate, lower plate and middle mould to constitute the finished product die cavity, on patrix, is provided with the sprue gate; Center at upper plate is provided with double-screw bolt, and the sprue gate is corresponding with the double-screw bolt position and form runner.
The number of upper die and lower die or finished product die cavity is two or more.
Both sides at counterdie are provided with locating piece.
The beneficial effect of the utility model: this mould adopts the combining structure of upper, middle and lower mould, and is rational in infrastructure, and reliable in quality is easy to operate, is easy to clean and the product deburring; The number of upper die and lower die or finished product die cavity is two or more, makes the reasonable quantity of finished product die cavity in the mould, is convenient to machining; Both sides at counterdie are provided with locating piece, make the location reliable, can guarantee the quality of product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a pad injecting molding die comprises patrix 1, counterdie 7 and finished product die cavity 5 before the engine; Mould 6 between patrix 1 and counterdie 7, being provided with is fixedly connected with upper plate 9 through alignment pin 2 below patrix 1, in the upper fixed of counterdie 7 lower plate 10 is arranged; Constitute finished product die cavity 5 by upper plate 9, lower plate 10 and 6 encirclements of middle mould; On patrix 1, be provided with sprue gate 3, be provided with double-screw bolt 11 in the center of upper plate 9, sprue gate 3 is corresponding with double-screw bolt 11 positions and form runner 4.
The number of patrix 1, counterdie 7 or finished product die cavity 5 is two or more.
Be provided with locating piece 8 in the both sides of counterdie 7.
During use, sizing material enters in the finished product die cavity 5 via runner 4, treat the sizing material cooling and shaping after; Take off alignment pin 2 earlier; Take down patrix 1 then, mould 6 in and then taking down takes out preceding pad of engine at last; And upper plate 9 and lower plate 10 pad before the engine taken off, accomplish the moulding of a pad before the engine.
