Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, for a mould for hollow plastic product, comprise cover half 3, coordinate the dynamic model 5 of matched moulds with cover half 3, cover half 3 and dynamic model 5 are equipped with shaping die cavity 6, the lower end of die cavity 6 is lower chamber 6-1, also comprises the hollow molding device be arranged on dynamic model 5;
The lower end of described dynamic model 5 has cavity 5-1, cavity 5-1 internal fixtion has guide pillar 7, the hollow molding device that guide pillar 7 is equipped with successively elastic parts, can slide along guide pillar 7, hollow molding device is in Working position under the guiding and position-limiting action of guide pillar 7, and the end of described guide pillar 7 is equipped with securing member;
Described hollow molding device comprises the pedestal 9 that can slide along guide pillar 7, the slide block 12 can doing along pedestal 9 side to pump pedestal 9 is equipped with, the pillar 4 of hollow forming slide block 12 is equipped with, the shape of pillar 4 mates with lower chamber 6-1 the hollow part forming plastic products, described pedestal 9 is provided with the drive unit driving slide block 12 to move, and the side of slide block 12 is provided with the fixture block 11 for positioning sliding block 12 moving distance.
As the embodiment improved, securing member adopts fastening bolt 13, by fastening bolt 13 by spacing for hollow molding device on guide pillar 7, use bolt fix, be convenient to the dismounting of device, it is more convenient that maintenance uses, in addition, after fastening bolt 13 and hollow molding device Long contact time, locally there is friction damage, in fastening bolt 13 and hollow molding device junction, pad can be installed, effectively buffering frictional force between the two.
