Plastic handles are limited on plastic containers after on device, and then form the plastic containers with plastic handles.Mould in the prior art
Expect that handle is installed after plastic containers shaping, plastic containers need the blowing mold with corresponding profile to participate in life when shaping
Production.The surface of plastic containers has most of dominant attribute relative to mould, it is only necessary to which mould inside passes through control
The profile of plastic containers forms corresponding curve, but plastic containers are influenceed to generate relative to mould by indent position
The surface of the recessive attribute of tool, the Curve Design for relying solely on mould itself is can not to form the structure at indent position.Only
Container, surface when mould production such as cylindrical shape is neatly without concave inward structure, it is only necessary to close two conventional moulds
And after, blowing is located at the base substrate in mould；But it is L-shaped to form an entirety in the vessel surface of the cylindrical shape
Blind hole, then the L-shaped projection even in mould with correspondence blind hole, but in final produce, generation container can not depart from mould
The problem of tool, such technical scheme is inadvisable, impracticable, without any economy for the social production business activities of reality
Value.
The need for prior art is in order to meet such container forming, install a set of with deformation and simulation mould additional on mould
The servicing unit of tool shaping function.As shown in figure 1, the servicing unit mainly includes straight line cylinder 9, push pedal 10, executive item 11.It is auxiliary
