Abstract
The invention discloses a manual outside-mould core pulling compression mould mechanism, which comprises male die fixing plate, a male die positioning pin, a pin bolt, bolts, a wrench, a die assembly pin, a guide pillar, an upper die holder plate, an insert, an inner movable molding block, a lower die holder plate and the like. Connection relationships among the parts are shown in drawings of specifications. A mould of the mechanism is a movable semipositive mould, and once pressing molding can produce one mould. In the mould, a loading chamber is formed above a mould cavity, has a sectional area larger than the size of a plastic product, and forms clearance fit with a male die; an annular extrusion surface is formed at a boundary between the loading chamber and the mould cavity, and is 4 to 5mm wide; the male die is downwards pressed until the male die contacts with the extrusion surface; and in each pressing cycle, if loaded raw materials are slightly excessive, the raw materials are discharged by the clearance fit between the male die and the loading chamber or by a special flash groove reserved on the male die. The mechanism has the advantages so as to be relatively more widely used, and is applicable to plastics with relatively higher molding flowability, and the plastic products with complex shapes and miniature inserts.
Description
Technical field
The present invention relates to mould for plastics, is a kind of manual mould compression molding of loosing core outward.
Background technology
Compression molding claims compacting tool set again, is mainly used in moulding thermosetting plastics goods.Compression forming is according to the pressing process condition mold to be heated to forming temperature (130～180 ℃), again molding powder is put into the reinforced chamber preheating of mold, matched moulds, pressurization, plastics are heated and the effect of pressurizeing and be full of die cavity, and after pressurize a period of time, plastic is hardened forming gradually, plastic is taken out in last die sinking, compression molding can be divided at present: 1, by the fixed form classification of mould on press: portable compression mould is arranged, semi-fixed type compression molding, fixed compression mould.2, by upper and lower mould fit structure tagsort: flash mould, half flash mould, positive mould are arranged, and according to the architectural feature of said mechanism, I am in conjunction with the following a kind of mechanism of the special invention of production line design experiences.
Summary of the invention
The present invention provides the loose core mechanism of compression molding of a kind of manual mould outward, its pressure transmission is good, move solid and reliable, the product quality grace, it is big that plastic member product bears pressure, so compactness is good, the intensity height, this mechanism is applicable to that compacting is complicated, dark chamber goods and mobile poor, the unit pressure height, the little plastics of superficial density, flash can become matched in clearance by punch with reinforced chamber by surplus raw material simultaneously.In every compacting circulation, feeding quantity has surplus slightly, and superfluous raw material is by the fit clearance in punch and reinforced chamber or offer special flash discharge on punch, and how much flash speed can regulate by gap length and flash groove.In addition, because this mechanism reinforced chamber sectional dimension is bigger than plastic products, punch can not scratch mold cavity surface not along the mold cavity wall friction, can not damage the plastic products outer surface during release yet.
The present invention is further described below in conjunction with accompanying drawing
1---counterdie seat board 2---screw 3---side thread forming bar
4---punch 5---die 6---fixed heads
7---the interior activity forming blocks of screw 8---pin 9---

The specific embodiment:
Be the manual mould compression molding structure of loosing core outward shown in the figure, this mould is to move half flash mould, once compacting, band side thread forming bar 3 after the compression moulding, utilizes the special-purpose wrench side thread forming bar 3 of back-outing, machine unloads mould bases outward and dismantles upper and lower mould, plastic is stayed in the die 5, behind the plastic of taking-up band forming blocks, and activity forming blocks 9 in taking out again, promptly take out plastic, 18 two of alignment pins, an end face is fixed on the interior activity forming blocks 9, and the other end and lower punch 19 matched in clearance.
Claims (1)
1. compression molding that manual mould is loosed core outward, its main feature is: this mould is to move half flash mould, because the sectional dimension in reinforced chamber is bigger than plastic member product, punch is not along the mold cavity wall friction, the die cavity wall surface can be do not scratched, the plastic products outer surface can be do not damaged during release yet.When outline is complex-shaped outside the plastic products, punch and reinforced chamber periphery mating surface shape can be simplified, with simplified processing process.It is applicable to moulding flowability plastics and complex-shaped preferably, has the plastic products of inserts.In addition, this mechanism pressure transmission is good.Product density is high.Therefore, goods are very good, and value is widely arranged.
