Description

Single layer two-color three-stage extrusion die structure

The author is related to a single-layer two-color three-stage extrusion die structure, especially one of the two-color feeds, which provides a single die-casting single-layer two-color three-segment plastic extrusion die.

According to the traditional plastic sheet metal manufacturing material, the process must add a large amount of plastic and a small amount of calcium carbonate. After the raw material is mixed, the calender is cooled and formed. The product cost is high and the mold is easily damaged. And the surface shape of the added small amount of calcium carbonate is irregular, which is easy to cause poor quality stability, so that the prepared plastic sheet is easily broken and difficult to be stored for a long time, and the uneven thickness is difficult to achieve natural environmentally-friendly paper use, so The lack of widespread implementation.

Moreover, at present, the conventional mold for the plastic sheet is extruded to extrude the die T-die structure, and the general extrusion die can only inject the material of the single color system to the T-die. The common input conversion seat is set by the upper and lower molds. The manifold channel is connected to the stream and is collected by the injection port to form a plastic product of a single color system. Therefore, the same type of extrusion mold cannot simultaneously form two finished products, so it is made into a plastic box for packaging or packaging. There is a lack of aesthetics, and the lack of efficiency and the lack of market competitiveness.

Furthermore, as for the "two-color extrusion die structure" of the National Patent Publication No. M492241, it can be analyzed from the drawings and the scope of the patent application, and it has the following defects: (1) especially its two modes. The group injects the plastic material liquid from the first feed hole into the first cavity through the drain channel (81), and the plastic material liquid is susceptible to the plastic temperature, fluidity coefficient and internal pressure factor due to the flow of the drainage channel (81). Under different circumstances, it is easy to cause the plastic internal knot to be extruded. The unevenness of the crystal generates internal stress, which causes the problem of flaws in the finished product; (2) especially when the liquid is injected into the second cavity from the second feed hole to the middle, the flow rate of the liquid is too large. The first cavity of the two sides is squeezed or the flow rate of the liquid is too small, so that the first cavity liquid on both sides is converged in the middle, resulting in a wide drop in the size of the die, and the width of the color section of the extruded product is not equal. Or the case where the two-color phase is infiltrated, so that the finished product does not conform to the expected specifications and increases the defective product; (3) especially the modulus of the first cavity and the second cavity is a fixed structure, which is guided by the fixed vertical angle only The flow direction of the two different color plastic liquids is introduced to the cavity. Therefore, the wide size specification of the color section of the extruded product is limited, so that the spacing of the extruded color segments cannot be changed effectively and is not ideal.

In view of the above-mentioned shortcomings of the above-mentioned practices, the author has exhausted his mind to study and design carefully, and has been adhering to the creative spirit of perseverance. After many discussions and trials and full improvement of the concept and improvement, the author has launched this creation.

The main purpose of this creation is to provide a single-layer two-color three-stage extrusion die structure, in which the upper and lower molds are correspondingly provided with an upper and lower manifold at a predetermined position on the opposite mold wall, and the upper and lower manifolds are used by the upper mold. The two portions of the chamber are respectively provided with two color section discharge inlet ports and two opposite ends of the upper and lower manifolds, respectively, and a diversion group with inner and outer guide columns for separating the chamber mold positions, The flow guiding group is oppositely disposed on the left and right sides of the collecting chamber, so that the chamber interval between the upper and lower collecting chambers forms an intermediate color mode and a left and right color mode, and the mold can be extruded. The two-color feeding material provides the plastic three-color segment die-casting die on the plastic extrusion molding to form a single-layer two-color three-stage double-material co-pushing and flattening the single-layer two-color three-stage finished product, thereby effectively reducing the cost and improving the competitiveness of the product selection.

The secondary purpose of this creation is to provide a single-layer two-color three-stage extrusion die structure, in which the flow dividing device sets the internal stress of the adjustable flow material of the throttling group of the heat-resistant piston throttle column at two predetermined portions of the branching channel. The combination of plastics and the combination can provide the effect of the flow of the raw material into the left and right color sections of the manifold, and achieve the effect of more uniform and stable diversion of the injection mold flow, and effectively adjust the internal crystallization of the plastic finished product. Both of them produce the problem of plastic heat changing internal stress.

Another object of the present invention is to provide a single-layer two-color three-stage extrusion die structure, wherein the upper and lower molds are provided with at least one flow guiding group having inner and outer guiding columns in the opposite manifold. The inner and outer guide columns of the group are tapered and have a curved edge at the inner and outer sides, respectively, and the spacing of the three color segments in the moving cavity can be freely adjusted. Stable diversion in the flow collecting chamber to make the environmentally-friendly regenerative flow material after the mixing on the average branching channel avoid the internal stress caused by the uneven crystallization inside the extruded plastic product due to the excessive injection of the raw material into the outlet. In turn, it is more efficient to achieve plastic extrusion molding.
