Abstract
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.The utility model is simple in structure, can effectively improve die orifice and extrude the also uniformity of the film of moulding, keeps its thickness deviation at positive and negative 0.005mm.
Description
Technical field
The utility model relates to a kind of casting head, relates 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.
Yet, existing casting head extrude and the film of moulding aspect uniformity or not ideal enough, the thick film of 0.1-0.3mm particularly.Therefore, be further improved.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of rack-style structure casting head that obtains more uniform die orifice moulding material is provided.
The utility model solves the technical scheme that its technical problem adopts: 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 from die orifice, extrude and the thick film of moulding, particularly 0.1-0.3mm more uniformly.
The utility model 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is internal structure schematic diagram embodiment illustrated in fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
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, the exit width in the narrow advection of gradation type road (be upper die body with lower mold body between gap) equate 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 from die orifice, extrude and the thick film of moulding, particularly 0.1-0.3mm more uniformly.
