Description
Technical Field
The utility model relates to a field of moulding plastics especially relates to a upset runner.
Background
Plastic mould runner: the section from the injection machine nozzle to the cavity is generally the same set of pipeline. The plastic mold has the function of smoothly filling the cavity with plastic melt to obtain a plastic product with clear outline and excellent internal quality. The common casting system (cold runner) and hot runner congealing casting system of the multi-cavity mold. A main flow channel: introducing a material into a mold, and introducing the molten material into a parting surface of the mold; a shunt channel: the melt from the main runner is split and diverted to guide the cavities or portions of the cavities. Therefore, the flow channel is generated. However, the existing through flow channel causes side wall friction due to the flow channel distribution problem, so that the temperature distribution of the flow section of the material flow is different; the solidified layer near the side wall is subjected to frictional shearing, the material temperature rises sharply, and the flow resistance is different, so that the conditions of unbalance and deformation of the die cavity member occur.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a upset runner realizes pressure, and the equal unanimous balance of temperature viscosity flows, solves the uneven and the condition of deformation of mould cave spare in the aspect of the runner.
The utility model provides a technical scheme that its technical problem adopted is: a turnover runner comprises a male die runner and a female die runner; the male die runner is arranged on the male die side; the female die runner is arranged on the side of the female die; one end of the male mold runner is communicated with the sprue bushing runner, and the other end of the male mold runner is communicated with the female mold runner during mold closing; the tail end of the female mold runner is communicated with the female mold cavity.
The male mold runner comprises a male mold main runner and a male mold sub-runner; the middle of the male mold main flow passage is communicated with the sprue channel; two ends of the male mold main runner are respectively communicated with the middle positions of the male mold sub runners.
The female mold runner comprises a female mold runner sub-runner; the middle position of the female die runner is communicated with the male die runner; and two ends of the female die runner are respectively communicated with the female die cavity.
The cross sections of the male mold main runner, the male mold sub-runner and the female mold sub-runner are basically consistent in area.
The utility model has the advantages that: the utility model discloses a turnover flow channel, which realizes balanced flow with uniform pressure and temperature and viscosity, and solves the unbalanced and deformed conditions of a mold cavity component in the aspect of flow channel; the male mold runner is turned over at a connection point of the male mold runner and the female mold runner, so that molten material in the runner is re-oriented, the flow form and orientation of the male mold runner are optimized, one side of the male mold runner, where the temperature of the molten material rises sharply, is located on the other side of the female mold runner after being turned over, and deformation caused by friction shearing heat on one side alone is prevented.

Detailed Description
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and embodiments, which are only used for explaining the present invention and are not limited to the protection scope of the present invention.
Examples
As shown in fig. 1 and fig. 2, the present embodiment provides an inverted runner, which includes a male runner and a female runner; the male die runner is arranged on the male die side; the female die runner is arranged on the side of the female die; one end of the male mold runner is communicated with the sprue bushing runner 1, and the other end of the male mold runner is communicated with the female mold runner during mold closing; the tail end of the female die runner is communicated with the female die cavity 5.
In the turnover runner of this embodiment, the male mold runner includes a male mold main runner 2 and a male mold sub-runner 3; the middle of the male mold main flow passage 2 is communicated with the sprue bush flow passage 1; two ends of the male mold main runner 2 are respectively communicated with the middle positions of the male mold sub-runners 3.
In an inverted runner of this embodiment, the female mold runner includes a female mold runner 4; the middle position of the female die runner 4 is communicated with the male die runner; and two ends of the female die sub-runner 4 are respectively communicated with the female die cavity 5.
In the inverted runner of the present embodiment, the cross-sectional areas of the male mold main runner 2, the male mold sub-runner 3 and the female mold sub-runner 4 are substantially the same. The sectional area of the runner is evenly distributed on the male die side and the female die side, so that the runner is overturned and balanced.
In the inverted runner of the embodiment, in the multi-cavity mold, plastic is filled under the condition that the temperature, the pressure and the viscosity of the molten material in the inverted runner are kept consistent, so that the flow balance which is influenced by the process conditions and the material types is not really needed; the melt in the flow channel is realigned to provide symmetric sol conditions in the next flow channel and to provide balanced material properties and flow regimes.
The turnover flow channel of the embodiment realizes balanced flow with consistent pressure, temperature and viscosity, and solves the problems of unbalance and deformation of the mold cavity component in the aspect of the flow channel; the male mold runner is turned over at a connection point of the male mold runner and the female mold runner, so that molten material in the runner is re-oriented, the flow form and orientation of the male mold runner are optimized, one side of the male mold runner, where the temperature of the molten material rises sharply, is located on the other side of the female mold runner after being turned over, and deformation caused by friction shearing heat on one side alone is prevented.
The above-mentioned embodiments should not limit the present invention in any way, and all the technical solutions obtained by adopting equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
