Abstract
The utility model relates to an improved structure of a wide extrusion flat die head. The improved structure comprises a die head which is composed of an upper die body and a lower die body. The improved structure is characterized in that a feed opening is formed in the middle of an upper die head, and is communicated with two secondary flow channels; a plurality of layers of secondary flow channels are connected to the lower parts of the secondary flow channels, each secondary flow channel on the upper layer corresponds to two equally divided secondary flow channels on the lower layer, each secondary flow channel on the last layer is connected with a flow channel manifold, and the flow channel manifolds are in a row to form the lower die body; the number of the secondary flow channels is changed with a 2N index, wherein N is a natural number from 1; the flow channel manifolds can be of a T-shaped structure, a fishtail-shaped structure, a hanger-shaped structure, a screw rod-shaped structure, a lotus-shaped structure and the like. According to the improved structure, a pre-distributed structure design is adopted, material flow passes through the feed opening and then enters the secondary flow channels to be pre-distributed, so that the material flow is uniformly distributed to both sides in the flow channels, then enters the corresponding flow channel manifolds and is collected into a main flow channel at last, thereby guaranteeing the uniform state of the material flow which flows out of the die head.
Description
Technical field
The utility model relates to a kind of extrusion die, refers to that especially a kind of wide cut extrudes the improvement structure of flat-mould head.
Background technology
Present extrusion molding die head used is all that charging aperture is directly communicated with single runner manifold, and this kind of structure is difficult to make material stream flow velocity distributed uniform on compared with length and width width die head to a certain extent.Be unfavorable for the production that products thickness is had relatively high expectations relatively.Therefore urgently the runner of existing wide cut extrusion molding die head is improved, to realize material stream flow velocity distributed uniform on compared with length and width width die head, ensure that the goods thickness of institute's extrusion molding is consistent.
Summary of the invention
The purpose of this utility model is to solve extrusion molding die head charging aperture in prior art to be directly communicated with single runner manifold, cannot meet the material stream irregular problem of the existing manufactured goods thickness of flow velocity distributed uniform on compared with length and width width die head, the improvement structure that provides a kind of wide cut to extrude flat-mould head, is convenient to flow velocity distributed uniform on wide cut die head.To achieve these goals, the utility model is achieved in that wide cut extrudes the improvement structure of flat-mould head, comprise the die head being formed by upper die body and lower mold body, it is characterized in that: the central authorities of upper die head are provided with charging aperture, charging aperture is communicated with two secondary channels, is connected with multilayer secondary channels under secondary channels, two secondary channels of dividing equally of the corresponding lower floor of secondary channels of last layer, each secondary channels of end layer connects a runner manifold, described runner manifold formation lower mold body in a row.The amount amount of described secondary channels is 2
nindex variation, N is the natural number of 1 beginning.The utility model adopts allocates structural design in advance, material stream enters secondary channels by charging aperture and allocates in advance, and be conducive to like this material stream and divide toward both sides uniformly in runner, then to the runner manifold of each correspondence, finally be pooled in sprue, thereby the state while ensureing material stream outflow die head is uniform.
Brief description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Sequence number in figure: die body Shang Xia 1.2; 3 charging apertures; 4 secondary channels; 5. runner manifold.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is elaborated.
Wide cut is extruded the improvement structure of flat-mould head, comprise the die head being formed by upper die body and lower mold body, it is characterized in that: the central authorities of upper die head are provided with charging aperture, charging aperture is communicated with two secondary channels, under secondary channels, be connected with multilayer secondary channels, two secondary channels of dividing equally of the corresponding lower floor of secondary channels of last layer, each secondary channels of end layer connects a runner manifold, described runner manifold formation lower mold body in a row.The amount amount of described secondary channels is 2
nindex variation, N is the natural number of 1 beginning.
Described runner manifold can be T shape structure; Fishtail type structure; Rack-style structure; Screw structure; Lotus type structure.
As shown in Figure 2, die head is by upper die body 1, and lower mold body 2 forms, and is provided with charging aperture 3 in die body central authorities, and charging aperture 3 is being communicated with multiple secondary channels 4, each secondary channels 4 corresponding a runner manifold 5.Material stream enters secondary channels 4 by charging aperture 3 and allocates in advance, be conducive to like this material stream and divide toward both sides uniformly in runner, then to the runner manifold 5 of each correspondence, be finally pooled in sprue, thereby the state while ensureing that material stream flows out die head is uniform.
Claims (2)
