Fig. 2 is an exploded view of the male mold and the female mold of the locking assembly of the present invention.
[ detailed description ] embodiments
The present invention will be further described with reference to the accompanying drawings and embodiments.
Referring to fig. 1 and 2, an autoclave molding die according to an embodiment of the present invention is shown.
The autoclave forming die comprises a male die 10, a female die 20 and a locking assembly 30, wherein the locking assembly 30 comprises a bolt 31 and a first rubber ring 33, the male die 10 is provided with a through hole 11, the female die 20 is provided with a screw hole 22 at a position corresponding to the through hole 11, and the screw hole 22 is provided with a containing groove 21 at one end close to the male die 10 or one end close to the female die 20 of the through hole 11.
When the male die 10 and the female die 20 are closed, the first rubber ring 33 is placed in the accommodating groove 21, and one end of the bolt 31 passes through the through hole 11 and the first rubber ring 33 in sequence and then is locked in the screw hole 22.
The utility model discloses an increase a first rubber ring 33 between formpiston 10 and bed die 20, and this first rubber ring 33 cover is established on screw 22, and storage tank 21 has been seted up in the position that corresponds first rubber ring 33, with this, when the compound die, bolt 31 is with formpiston 10, the first rubber ring 33 of bed die 20 cooperation is locked, first rubber ring 33 is by formpiston 10, in storage tank 21 is arranged in to bed die 20 extrusion, realize through-hole 11, seal between the screw 22, with this, can prevent the utility model discloses the mould is heated to melt in autoclave molding technique resin and is got into through-hole 11 and screw 22 and live bolt 31 bonding, and then can be convenient for bolt 31 unscrew, be convenient for divide the mould, prevent to damage the thread in bolt 31 and the screw 22, improve the production efficiency among the autoclave molding technique.
