Description

Reductor loam cake mould

Technical field

The utility model relates to a kind of injection forming mold, especially a kind of reductor loam cake mould.

Background technology

Along with the progress of society, the injection forming mold industry has had larger development, and the equipment of injection forming mold is also had higher requirement.

A kind of mould commonly used in the injection forming mold, its effect is to use mould to produce finished product, in the prior art, sprue generally all is arranged on core and lower module and matches on the upper surface of end face, because such structure needs excessive air pressure that raw material is evenly distributed between die cavity and the core, cost is relatively high, has reduced operating efficiency.

The utility model content

The purpose of this utility model is a kind of reduction cost that designs for the deficiency that solves above-mentioned technology, the reductor loam cake mould of increasing work efficiency.

The reductor loam cake mould that the utility model is designed, comprise upper module, die cavity, core and lower module, core is fixed in the lower module, one side of lower module is fixed with cylinder, be fixed with take-up housing on the piston rod of cylinder, be fixed with slide block on this take-up housing, take-up housing and slide block be movable being embedded in core and the groove that lower module matches simultaneously, the position of matching with core in upper module is die cavity fixedly, and be positioned at the top of core, be provided with sliding chamber and be positioned at above the take-up housing at the aperture position of die cavity, upper surface, sliding chamber is provided with sprue, this sprue is provided with and waters material seat, and watering on the opening that waters the material seat and the die cavity expects that the road is corresponding.

During use, by the sprue that is located at upper surface, sliding chamber raw material is injected between die cavity and the core, treat to promote slide block movement by take-up housing after the moulding of reductor loam cake, then upper module separates with lower module, and the push rod in the core is released the reductor loam cake.

For can be in the shaping work process better Exhaust Gas, be equipped with corresponding exhaust duct on the upper surface of the both sides that described core and lower module match.

For die cavity and core are walked about in the engineering in work, be respectively equipped with two grooves and two projections on four angles of core and die cavity, the groove on the described core matches with projection on the die cavity, and the projection on the core matches with groove on the die cavity.

The designed reductor loam cake mould of the utility model reduces cost, makes the better effects if of finished product moulding, increases work efficiency.

Description of drawings

Fig. 1 is the upper module structural representation of embodiment 1;

Fig. 2 is the lower module structural representation of embodiment 1.

Among the figure: cylinder 1, groove 2, take-up housing 3, slide block 4, lower module 5, core 6, projection 7, groove 8, upper module 9, sliding chamber 10, die cavity 11, sprue 12, water material seat 13, water material road 14, exhaust duct 15.

The specific embodiment

The utility model will be further described by reference to the accompanying drawings below by embodiment.

Embodiment 1:

Such as Fig. 1, shown in Figure 2, the described reductor loam cake of the present embodiment mould, comprise upper module 9, die cavity 11, core 6 and lower module 5, core 6 is fixed in the lower module 5, one side of lower module 5 is fixed with cylinder 1, be fixed with take-up housing 3 on the piston rod of cylinder 1, be fixed with slide block 4 on this take-up housing 3, take-up housing 3 and slide block 4 be movable being embedded in core 6 and the groove 2 that lower module 5 matches simultaneously, the position of matching with core 6 in upper module 9 is die cavity 11 fixedly, and be positioned at the top of core 6, be provided with sliding chamber 10 and be positioned at above the take-up housing 3 at the aperture position of die cavity 11,10 upper surfaces, sliding chamber are provided with sprue 12, and this sprue 12 is provided with and waters material seat 13, and watering on the opening that waters material seat 13 and the die cavity 11 expects that road 14 is corresponding; For can be in the shaping work process better Exhaust Gas, described core 6 and lower module 5 match and are equipped with corresponding exhaust duct 15 on the upper surface of both sides; Walk about in the work engineering in order not make die cavity 11 and core 6, be respectively equipped with two grooves 8 and two projections 7 on four angles of core 6 and die cavity 11, groove 8 on the described core 6 matches with projection 7 on the die cavity 11, and the projection 7 on the core 6 matches with groove 8 on the die cavity 11.

During use, by the sprue 12 that is located at 10 upper surfaces, sliding chamber raw material is injected between die cavity 11 and the core 6, then the reductor loam cake begins moulding between die cavity 11 and core 6, exhaust duct 15 Exhaust Gas in forming process, after treating the moulding of reductor loam cake, promote slide block 4 motions by take-up housing 3, then upper module 9 separates with lower module 5, and the push rod in the core 6 is released the reductor loam cake.

The described reductor loam cake of the present embodiment mould reduces cost, makes the better effects if of finished product moulding, increases work efficiency.
