Problems solved by technology
[0005] In addition, because the feed pipe of the current injection mold is a transparent pipe, the injection material flows out directly from the pipe. The diameter of the outflow injection material is too large, the thickness is too thick, and the viscosity is too viscous, so it is not conducive to modification. The gas uniformly modifies it, and often the surface of the injection molding material fluid is modified, but the middle is not modified

Abstract
The invention discloses an improved injection mould. The improved injection mould comprises a bottom mould (1) and a top mould (2), and is characterized in that a through hole for passing an improved device (3) through is formed in the top mould (2); the lower end of the improved device (3) penetrates through the through hole, and the upper end of the improved device (3) is communicated with a feed pipe (4); a discharge net (9) is arranged at the outlet of the feed pipe (4); the inlet of the feed pipe (4) is connected with a flow control device. According to the improved injection mould, the improved device is additionally arranged between the feed pipe and an injection cavity, so that the application range of injection materials is enlarged, the quality of finished product plastic parts is improved, and the production cost is effectively reduced; the discharge net is arranged at the outlet of the feed pipe, and the flow control device is designed at the outlet of the feed pipe, so that the improved homogeneity and uniformity of the finished product plastic parts are ensured, and the rate of finished products and the production efficiency are greatly improved.
Description
technical field [0001] The invention relates to a modified injection mold, which belongs to the technical field of molds. Background technique [0002] At present, molds are widely used in production enterprises, which have high work efficiency and convenient operation. Thermoplastic injection molding has a short molding cycle, high production efficiency, and the injection material has little wear on the mold. It can form large quantities of plastic parts with complex shapes, clear surface patterns and markings, and high dimensional accuracy. [0003] However, the existing injection molds generally do not have the modification function. After modification, the same injection material can have different properties according to the requirements, such as antibacterial and hydrophobic properties after modification; or through modification. Improve plastic quality, such as density, hardness, precision, appearance, processability, transparency, mechanical properties, electromagne...
