Abstract
The invention discloses a curtain coating die head with a clothes-hanger-type structure. The curtain coating die head with the clothes-hanger-type structure comprises an upper die body and a lower die body which are connected and assembled by a bolt; a charge hole and a flow channel are formed between the upper die body and the lower die body; the flow channel is a clothes-hanger-type flow channel with more than two stages in sequential arrangement from top to bottom, wherein the front stage of clothes-hanger-type flow channel is communicated with the following clothes-hanger-type flow channel; the first stage of clothes-hanger-type flow channel is communicated with the charge hole. The coating die head with the clothes-hanger-type structure is simple in structure, can effectively improve the uniformity of films which are extruded and formed from a die opening, and keeps the thickness deviation be within minus 0.005mm-0.005mm.
Description
Technical field
The present invention relates to a kind of casting head, relate in particular to a kind of rack-style structure casting head.
Background technology
Casting head is the profiled part of casting machine, and its function is the plastic melt making from casting machine machine barrel, well distributed in die head runner, to extruding and moulding from die orifice under speed uniformly.
But, existing casting head extrude and the film of moulding aspect uniformity or not ideal enough, the particularly thick film of 0.1-0.3mm.Therefore, be further improved.
Summary of the invention
Technical problem to be solved by this invention is that a kind of rack-style structure casting head that obtains more uniform die orifice moulding material is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rack-style structure casting head, comprise upper die body and lower mold body, described upper die body is connected by bolts assemblies with lower mold body, between described upper die body and lower mold body, be provided with charging hole and runner, described runner is rack-style runner more than two-stage, is arranged in order from top to bottom, wherein, previous stage rack-style runner is communicated with rear one-level rack-style runner, and first order rack-style runner is communicated with charging hole.
Further, the cross section of rack-style runner is rounded.
Further, previous stage rack-style runner is communicated with rear one-level rack-style runner by the narrow advection of gradation type road, and the exit width in the narrow advection of gradation type road equates with die orifice width.
Research shows, adopts rack-style runner more than two-stage, can change flow rate and the squeeze pressure of material in die head, can extrude and the thick film of moulding, particularly 0.1-0.3mm from die orifice more uniformly.
The present invention is simple in structure, can effectively improve die orifice and extrude the also uniformity of the film of moulding, keeps barrier film deviation thickness at positive and negative 0.005mm.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is internal structure schematic diagram embodiment illustrated in fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to accompanying drawing, the present embodiment comprises upper die body 5 and lower mold body 4, described upper die body 5 is connected by bolts assemblies with lower mold body 4, between described upper die body 5 and lower mold body 4, be provided with charging hole 6 and runner, described runner is two-stage rack-style runner, be first order rack-style runner 1 and second level rack-style runner 2, described first order rack-style runner 1 and second level rack-style runner 2 are arranged in order from top to bottom, described first order rack-style runner 1 is communicated with second level rack-style runner 2, and described first order rack-style runner 1 is communicated with charging hole 6.
Described first order rack-style runner 1 is communicated with second level rack-style runner 2 by the narrow advection of gradation type road, and the exit width (being the gap between upper die body and lower mold body) in the narrow advection of gradation type road equates with die orifice width.
The cross section of described first order rack-style runner 1 and second level rack-style runner 2 is rounded.
Certainly, in the present embodiment, runner also can be three grades of above rack-style runners, does not repeat them here.
Research shows, adopts rack-style runner more than two-stage, can change flow rate and the squeeze pressure of material in die head, can extrude and the thick film of moulding, particularly 0.1-0.3mm from die orifice more uniformly.
