Abstract
The invention discloses a blowing machine die head device capable of controlling the wall thickness at multiple points. The blowing machine die head device comprises a die core and a die sleeve, wherein the die sleeve is conical or frustum-shaped and is sleeved outside the die core; a plurality of pressure applying mechanisms are arranged on the outer wall of the die sleeve and are used for applying pressure to the outer wall of the die sleeve to adjust the distance between a position on the outer wall of the die sleeve and a corresponding position on the die core so as to adjust the wall thickness of a blowing-formed product; and the die sleeve comprises a plurality of sheet-shaped spring steel die sleeves and is formed by conically stacking a plurality of sheet-shaped spring steel die sleeves, so that the elastic die sleeve is formed and can elastically deform under the pressure application of the pressure applying mechanisms. According to the blowing machine die head device capable of controlling the wall thickness at the multiple points, due to specific design of the die sleeve, a hydraulic oil cylinder is arranged on the die sleeve, so that the distance between the die sleeve and the die core can be controlled at the multiple points, and the wall thickness of a blowing-formed product can be controlled at the multiple points.

Technical field
The invention belongs to the blow moulding equipment technical field, relate to a kind of blow moulding machine die head device, but relate in particular to a kind of blow moulding machine die head device of multiple spot control wall thickness.
Background technology
Existing blow moulding machine mainly comprises frame, extrusion mechanism, die head, clamping, bottom blow structure, and its working method is: after sealant was gushed out, the wind-force that utilizes machine to produce by boasting blew the die cavity that is attached to definite shape with plastomer, thereby makes product.Plastics are melted in screw extruder and quantitatively extrude, and then by closing the film moulding, by vane blowing cooling, have hauling machine to draw by certain speed then again, and up-coiler is wound into volume.
Existing blow moulding machine can't be adjusted the wall thickness of blow molded product by multiple spot, thereby can not realize the preparation of specific products.
In view of this, nowadays press for a kind of new blow moulding machine die head device of design, in order to overcome the above-mentioned defective of existing equipment.
Summary of the invention
Technical problem to be solved by this invention is: but the blow moulding machine die head device that provides a kind of multiple spot to control wall thickness, but the wall thickness of multiple spot control blow molded product.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
But a kind of blow moulding machine die head device of multiple spot control wall thickness, described die head device comprises: core rod, die sleeve; Tapered or the taper type of described die sleeve is enclosed within outside the core rod; The outer wall of described die sleeve is provided with some pressure exerting arrangements, in order to the die sleeve outer wall is exerted pressure, adjusts the distance between die sleeve outer wall correspondence position and the core rod relevant position, thereby adjusts the wall thickness of this position blow molding product.
As a preferred embodiment of the present invention, described die sleeve comprises some plate-like spring punching block covers, and die sleeve is built up by some plate-like spring punching block cover circular cones, forms the rubber-like die sleeve, so that elastic deformation to take place under the exerting pressure of pressure exerting arrangement.
As a preferred embodiment of the present invention, described die sleeve is the truncated cone of hollow, and the base angle of the frustum of a cone is 60 °～90 °.
As a preferred embodiment of the present invention, the base angle of the described frustum of a cone is 75 °.
As a preferred embodiment of the present invention, described pressure exerting arrangement comprises hydraulic jack or cylinder, and hydraulic jack or cylinder are arranged at the outer wall of die sleeve by bindiny mechanism.
Beneficial effect of the present invention is: but the blow moulding machine die head device of the multiple spot that the present invention proposes control wall thickness, by the design of peculiar die sleeve and at die sleeve hydraulic jack is set, but the distance of multiple spot control die sleeve and core rod, thereby the wall thickness of multiple spot control blow molded product.
Description of drawings
