The blowing of plastics is methods of a kind of moulding hollow product, and the residual stress of blow molded product is less, and the performance of various strains such as stretch-proof, impact, crooked and environment is higher, has higher impact flexibility and rigidity and serviceability preferably.And the plastic complexity of blowing, irregular and be all-in-one-piece goods, so the application of blow-molded article in daily production and life is more and more widely.Blow molding process is made of two basic steps: XianCheng's parison, inflation (with stretching) parison is come with compressed air (with the stretching bar) in the back, make it to be adjacent to mold cavity, give goods the shape of die cavity and size, and cool off it, blowing can guarantee the external dimensions and the shape of goods preferably, the large-scale and hollow product that can can't produce with higher production efficiency moulding additive method.Yet, hollow product by the blow molding process moulding, because the limitation of technology, the turning of product, corner angle, groove will become bigger circular arc or spherical transition as far as possible with ribs, because parison is under compressed-air actuated effect, power to the mold cavity all directions is impartial, when having the turning on the mould, blank B at first touches two adjacent faces of die cavity, residual air between adjacent two faces of blank B and die cavity is squeezed into gas bag, form the dead angle A that blank can't arrive,, therefore between adjacent two faces on the goods, form bigger circular arc or spherical transition because blank B can't arrive corner, under the situation that increases air pressure, it is thin excessively these glue positions, position to occur, and intensity does not reach instructions for use, even can not moulding.Like this, when a plurality of parts of product needed assemble, mannequin's stage property for example, after the stage property parts assembling that is made by blowing, depression (as shown in Figure 2) appears in adjacent joining place, the surface cunning that has some setbacks, after putting on clothes, plain, during especially for displaying underwear or fitted garment, this defective is more obvious, thus the whole bandwagon effect of influence.Because mannequin's stage property that blowing is produced has above scarce limit, make that a large amount of mannequin's stage properties still adopts traditional resin to add the mode of making by hand of glass fibre at present.

The utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of blow mold of the mannequin's of production stage property is provided.

The technical scheme of the utility model mannequin stage property jockey is: a kind of blow mold that is used to produce mannequin's stage property, it is characterized in that: described mould comprises the die cavity that is used for moulding mannequin stage property, be inlaid with mold insert on the described die cavity, the part surface of mold insert constitutes a part of forming surface of die cavity, have the turning between the forming surface on the mold insert and the forming surface of die cavity, the junction between described die cavity and the mold insert is provided with the gap.

For obtaining molding effect preferably, the width in described gap is 5～25 decimillimeters.

As further improvement of the utility model, the forming surface center on the described mold insert is provided with boss, and the height of boss is 1.5～3.5 millimeters.

According to above technical scheme, the mold insert clearance-type mould that the utility model provides is compared with existing blow mold, break through the production bottleneck of blowing industry, and blow molding process can not be produced the join technology prejudice of product of right-angle side, manufacture out the blow molded product of non-arc transition, and realize successfully that by the control blow moulding cycle a plurality of blow molded product build-up tolerances cooperate.Do not need to adopt big arc transition between the adjacent surface of product, the linking between each parts is smooth and easy, and when being used to produce mannequin's stage property, whole impression is good, and support garment better, can not make the abnormal depression of the clothes of being showed.When realizing suitability for industrialized production, stopped product cracky that traditional handicraft is produced, easy cracked root problem, both improved product quality, improved the service life of product again.Simultaneously workman's operating environment be improved significantly, reduce the injury of industrial pollution to human body.
