Description

The head die gap electric adjusting apparatus of blow moulding machine

Technical field

The invention belongs to be blow molded field of mechanical technique, and in particular to a kind of head die gap electric adjustable of blow moulding machine is self-contained Put.

Background technology

Foregoing blow moulding machine be blow hollow plastic product equipment, hollow plastic product such as all types of plastic Bottle ＆ Can, add human relations Bucket, water tank, stacking bucket or even the pallet for heap south pile goods, etc..

Foregoing die orifice is also referred to as mouth mold or die head mouth mold by custom, and can be no lack of in disclosed Chinese patent literature It is seen in the technical information of the die geometry on blow moulding machine, such as CN2837051Y（Circular die device for blow molding machine）、 CN102114702B（The die geometry of plastic blow molding machine）、CN102152472B（The mouth mold knot of the improved plastic blow molding machine of structure Structure）、CN102145540B（The mouth mold mechanism of plastic blow molding machine）、CN202825606U（A kind of mouth mold mechanism of blow moulding machine）、 CN203305506U（Blow molding machine mouth mold）、CN203472117U（A kind of multiplex mouth mold for blow moulding equipment）With CN205185287U（The die geometry of hollow plastic blow molding machine）, etc..

The melt between die sleeve inwall and core rod outer wall can be changed by the lift adjustment of the die sleeve to die geometry system The width in the discharging opening gap of runner（That is die gap width）, so that the wall thickness of the plastic parison of melting is according to need to change and most The wall thickness of the hollow plastic product that blowing obtains is set to meet technological requirement eventually, because different purposes, the hollow plastic of different size Wall of a container thickness is different.Especially, in plastic parison forming process, also according to need to be to the discharging opening gap of foregoing melt flow channel It is adjusted, with the control for realizing being distributed system of parison wall thickness, obtains the more uniform hollow plastic product of Thickness Distribution.

Prior art is universal using oil cylinder as the power of the structural system of head die orifice lash adjusting device, using oil cylinder Shortcoming is：Adjustment precision, energy consumption be big when influenceing the pole to gap because of the hysteresis quality in existence time, hydraulic oil easy to leak and Influence operating environment and also corresponding Hydraulic Station need to be equipped with.

" the extrusion-blown modling head die mouthful gap motorized adjustment that Chinese invention patent Authorization Notice No. CN101966750B recommends Device and its implementation and application " can be made up using the foregoing drawback of oil cylinder, and also eliminates United States Patent (USP) US5851570 （A kind of extrusion-blown modling head die mouthful gap electric adjusting device）Deficiency.

But read by the full text to above-mentioned CN101966750B：Because it needs to use forward and reverse to drive Motor（Two motors）, clutch reversing arrangement, reductor and be driven forward and reverse motor and clutch reversing arrangement Two Timing Belts of connection etc.（Referring to the 0026th section of the patent specification）, thus structure is complex, to manufacturing, assemble, make With and daily managing and protecting there is corresponding trouble.It is necessary to be improved in view of this, technical scheme described below is Produce under this background.
