4) it stocks up and material is inserted into material chamber.
5) upper cover plate and half round table surface of punch-pin are fixed with bolt, as shown in Figure 10.
6) hanging ring of punch-pin and cavity plate two sides is installed, and cavity plate is installed on punch-pin, is then molded in press machine,
As shown in figure 11.
7) curing molding
8) mold is hung oneself down from press machine, first opens cavity plate with liftout bolt, then take out upper cover plate and side block blocks
Fastening screw removes upper cover plate and side block blocks, then takes out side slide, then gently tapped with rubber hammer product can be completed it is de-
Mould.
9) overlap and burr of product are removed.

Product
Specific embodiment
Embodiment:
The present embodiment is certain model deep camber, open, the mold and forming method of product on thin-wall construction composite material bullet.
Mold use semi-enclosed, single-chamber, lateral pressurization structure, including punch-pin, cavity plate, upper cover plate, side block blocks, side slide, hanging ring and
Fastening bolt.Mould structure is as follows:
Cavity plate is rectangle structure, and there is the semicircle ring groove with gradient in centre, has through-hole in groove, forms entirety with punch-pin
Cooperation, and hanging ring is installed in two sides.Quantity 1.
Punch-pin is the composite structure of semi-annular shape boss and rectangle bottom plate, and boss top surface and both ends of the surface have screw thread
Hole has step on semi-annular shape boss, for the fixed and positioned of upper cover plate for the locking and fixation of upper cover plate bolt.
Bottom plate is equipped with threaded hole, for the locking and fixation with side block blocks.Punch-pin two sides are installed by hanging ring.Quantity 1.
Upper cover plate is semicircle ring structure, and there is the groove of semi-annular shape in semicircular ring upper surface, and groove inner surface has through-hole, molding
When formed and cooperate with the step of punch-pin boss, be the component part of mold cavity.Quantity 1.
Side slide is a quarter circular ring structure of the inside and outside side with gradient, is located on punch-pin bottom plate when molding, is mold
The component part of type chamber.Quantity 2.
Side block blocks are trapezium structure, and centre has counter sink, positioned at the both ends of punch-pin semi-annular shape boss structure when molding,
It is the component part of mold cavity.Quantity 2.
Forming process is as follows:
Mold prepares: side block blocks is first placed in the boss both ends of punch-pin, side block blocks and bottom plate are locked with screw, is fixed,
Then side slide is placed on punch-pin bottom plate, forms the mold cavity of opening upwards, then preheat 80 DEG C of mold；
Stock: pine is torn into staple fiber premix, and weighs 1100 ± 10g；
Mold filling: in order to ensure mold filling uniformity, load weighted staple fiber premix is divided into equiponderant 4 aliquot, often
275 ± 2.5g of part, uniformly inserts corresponding mold cavity；
Molding pressurization: after completing mold filling, being locked on the boss of upper cover plate lid to punch-pin and with fastening bolt.In cavity plate
After semicircle annular groove is directed at the boss of punch-pin, cavity plate is put on punch-pin, is then integrally placed on mold on pressing machine table-board.It utilizes
Cavity plate drives side slide when pushing, and the pressure of press machine vertical direction is moved inward by side slide, is converted to lateral conjunction
Molding pressure.When cavity plate lower surface and punch-pin plate upper surface touch, that is, mold in place.
Elevated cure: being warming up to 100 DEG C for mold, keep the temperature 10min, then proceedes to be warming up to 180 DEG C, keeps the temperature 60min；
Demoulding: after 180 DEG C of heat preservation 60min, stop heating, be reduced to room temperature to be opened to mold.First opened with liftout bolt
Then cavity plate successively removes upper cover and side block blocks, take out side slide, finally gently tap product with rubber hammer, production can be completed
The demoulding of product.
Pincers: deburring and overlap.
