Abstract
The utility model relates to a multi-layer highly separating film blow molding machine, particularly relates to an eleven-layer coextrusion double helix plane stacking machine head, which comprises a core mold, runner plates, connecting plates, a top plate, an inner opening mold, an outer opening mold, screws and a copper stick. The runner plates, the connecting plates and the top plate are sleeved on the core mold in stacking mode, wherein the numbers of the runner plates and the connecting plates are both eleven, and the runner plates and the connecting plates are connected in series closely through the screws. The eleven-layer coextrusion double helix plane stacking machine head replaces traditional tubular flow, layer number of the machine head can be combined optionally, and the structure is simple. The runner without dead angles is adopted, therefore cleaning is thorough. Tensile strength and breaking extension rate of products are high, uniformity of discharged materials is good, and working efficiency of the blow molding machine is effectively improved.
Description
Technical fieldThe utility model relates to multi-layer co-extruded high-isolation film blowing machine, concrete relates to a kind of eleventh floor co-extrusion double spiral plane stack head, belongs to plastic cement processing equipment field.
Background technologyBlow moulding machine is to be used for the indispensable process equipment of plastic cement processing industry.The work quality of blow moulding machine is decided by its head, so the blow moulding machine head is the guarantee of whole blow moulding machine operation.Domestic in the past existing five layers, seven layers and nine layers of head all are inclined flow passage formula heads, though can keep operate as normal, the head discharging has the dead angle, are difficult to cleaning; And product tensile strength and the elongation at break produced are low, and the evenness of discharge degree is poor.
Summary of the invention
The utility model has been to solve above-mentioned technological deficiency, provide a kind of simple in structure, production intensity is high, the eleventh floor co-extrusion double spiral plane stack head of good evenness, multilayer number.
Technical scheme of the present invention is: eleventh floor co-extrusion double spiral plane stack head comprises core, runner dish, terminal pad, takes over a business, internal orifice mould, collar extension mould, screw, copper rod; Runner dish, terminal pad and the shape of taking over a business to be to superpose are placed on the core, and wherein runner dish and terminal pad respectively have 11, and with screw that its series connection bolt is tight; Adopt side charging melt with the central axis symmetry, moving at every layer stack surface current.
Beneficial effect of the present invention is: count head with bottom in the past and compare, adopt double spiral plane stack head, replaced traditional tubular to flow, the head number of plies can combination in any, and is simple in structure; The employing of no dead angle runner, cleaning are thoroughly; Product tensile strength of producing and elongation at break are high, and the evenness of discharge degree is good, effectively raises the operating efficiency of blow moulding machine.
Description of drawings
Fig. 1 is the structural representation of eleventh floor co-extrusion double spiral plane stack head of the present invention.
Fig. 2 is the distribution map that fused materials flows in the runner dish of the present invention.
Among Fig. 1,1, core, 2, the runner dish, 3, terminal pad, 4, copper rod, 5, screw, 6, take over a business, 7, the internal orifice mould, 8, second screw, 9, the collar extension mould.
The specific embodiment
Eleventh floor co-extrusion double spiral plane stack head comprises core 1, runner dish 2, terminal pad 3, takes over a business 6, internal orifice mould 7, collar extension mould 9, screw 5, copper rod 4; Runner dish 2, terminal pad 3 and take over a business 6 and be the stack shape and be placed on the core 1, wherein runner dish 2 respectively has 11 with terminal pad 3, and with screw that its series connection bolt is tight.
Charging aperture gets into fused materials from the center; Be divided into stereotyped writing or 16 bursts of materials flows; Material arrives the starting point place of each screw channel in eight or 16 head threads then, and each burst molten stream is divided into the axial materials flow b of two bursts of materials flows on the formed annular gap of a and the spiral materials flow of in helicla flute, flowing forward again.Extruding on the direction, c is fewer and feweri, and on the contrary, the b side is more and more.Between the starting point and terminal point of helical flow path, accomplished by the continuously processes of axial flow purely of spending of pure helical flow more.
Claims (1)
1. eleventh floor co-extrusion double spiral plane stack head comprises core, runner dish, terminal pad, takes over a business, internal orifice mould, collar extension mould, screw, copper rod; It is characterized in that runner dish, terminal pad and take over a business to be the stack shape being placed on the core, wherein runner dish and terminal pad respectively have 11, and with screw that its series connection bolt is tight; Adopt side charging melt with the central axis symmetry, moving at every layer stack surface current.
