Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for facilitating slag removal. Background Technology

[0002] Injection molds are tools used in the plastics processing industry, working in conjunction with plastic molding machines to give plastic products a complete shape and precise dimensions. Due to the wide variety of plastic types and processing methods, and the varying complexity of plastic molding machines and products, plastic molds also come in many types and structures. The processing equipment corresponding to plastic injection molds is a plastic injection molding machine. The plastic is first heated and melted in the heating barrel at the bottom of the injection machine. Then, driven by the screw or plunger of the injection machine, it enters the mold cavity through the injection nozzle and the mold's gating system. The plastic cools and hardens, and the product is then demolded. Its structure typically consists of molding components, a gating system, guiding components, an ejection mechanism, a temperature control system, a venting system, and supporting components. The manufacturing material is usually plastic mold steel modules, with common materials including carbon structural steel, carbon tool steel, alloy tool steel, and high-speed steel. Injection molding is generally only suitable for the production of thermoplastic products. Plastic products produced using injection molding are very widespread, ranging from daily necessities to various complex machinery, electrical appliances, and transportation parts. It is the most widely used processing method in plastic product manufacturing.

[0003] Traditional molds typically require opening the mold to remove the solidified plastic from the cold slug nozzle, which affects mold use and reduces injection molding efficiency. Utility Model Content

[0042] The fixed mold part 2 also includes a vertical channel 22 and a horizontal hole group. The vertical channel 22 is located on one side of the fixed mold part 2, and the horizontal hole group is located on the other side of the fixed mold part 2 and is adjacent to the vertical channel 22. The first fixed rod 46 is located in the vertical channel 22 and can move up and down along the vertical channel 22.

[0044] Molten plastic is injected into injection section 3. The molten plastic flows along injection section 3 to the gap between moving mold section 1 and fixed mold section 2. After the gap is filled, the injection of molten plastic is stopped. After holding pressure and cooling for a period of time, the screws on moving mold section 1 are unscrewed, and moving mold section 1 is removed from fixed mold section 2. The molded plastic is removed from the top of fixed mold section 2, and then moving mold section 1 is fixed to fixed mold section 2 with screws. The next injection can then be performed. Between each injection interval, solidified cold plastic material is generated at the bottom of injection section 3. After the next injection begins, the cold plastic material... The material is squeezed downwards by the molten plastic and accumulates at the top of the discharge port 21. Meanwhile, the molten plastic flows from the side holes into the gap between the moving mold section 1 and the fixed mold section 2, where it is held under pressure. As injection molding progresses, more and more cold material accumulates and needs to be discharged outside the mold. The gripper block 413 is pinched and pulled outwards, causing the moving rod 41 to rotate around the connecting post 493 and disengage from the vertical groove 24. When the moving rod 41 reaches the horizontal position, the limiting stop plate 412 abuts against the second fixed rod 49, preventing the moving rod 41 from rotating. The moving rod 41 is then pushed inwards along the transverse channel 23. Rod 41, via the second fixed rod 49, moves the cutting assembly toward the discharge port 21, cutting the cold material in the discharge port 21. When the cutting assembly is fully positioned in the discharge port 21, the cold material inside the discharge port 21 is cut off. Simultaneously, the first fixed rod 46 extends out of the vertical channel 22. By gripping the first fixed rod 46 and moving it downwards along the vertical channel 22, the connecting block 48 disengages from the connecting groove 47, and the limiting block 45 enters the guide groove on the side wall of the discharge port 21, keeping the cutting assembly moving vertically. The cutting assembly pushes the cut cold material to overcome the friction of the discharge port 21. Move downwards to discharge the cold material out of the mold, then push the first fixed rod 46 upwards. The first fixed rod 46 moves the cutting assembly upwards until it reaches the top of the discharge port 21. At this time, the connecting groove 47 wraps around the connecting block 48. Grasp the gripping block 413 and pull it outwards to pull the cutting assembly out of the discharge port 21. Subsequent cold material can continue to accumulate in the discharge port 21. When the moving rod 41 is completely pulled out of the transverse channel 23, push the gripping block 413 upwards. The moving rod 41 rotates around the connecting column 493 until it enters the vertical groove 24, thus completing one round of cold material discharge.
