Description

Technical Field

[0001] The utility model belongs to the technical field of cooling mechanisms, and relates to a water-cooling mechanism for plastic extrusion drawbars. Background Art

[0002] The extrusion method of a plastic extruder generally refers to melting plastic at a high temperature of about 200 °C. The melted plastic is extruded and formed when passing through a mold. It is a method of continuously forming materials in a flowing state through a die by heating and pressurizing in an extruder, also known as "extrusion molding". Compared with other molding methods, it has the advantages of high efficiency and low unit cost. The extrusion method is mainly used for the molding of thermoplastic plastics and can also be used for certain thermosetting plastics. Existing plastic extrusion drawbars need to be cooled and then processed. Currently, when the drawbars are cooled, they directly pass through a water tank. However, since the sizes of the drawbars coming out of the injection extruder are different and they directly pass through a guide roller and enter cold water, the drawbars will coagulate with each other, resulting in the scrapping of the drawbars and the need to recycle and re-inject, increasing the workload. Therefore, in view of the above problems, a water-cooling mechanism for plastic extrusion drawbars is proposed. Summary of the Utility Model

[0028] Among them, after a cooling water tank 2 is provided on one side of the injection and extrusion machine 1, a cold water tank 3 for storing cold water is directly provided below the cooling water tank 2. Then, a circulating pump 4 and a water pipe 5 are connected between the cooling water tank 2 and the cold water tank 3. During the wire drawing and cooling work, the water in the cooling water tank 2 can be circulated and cooled at any time.

[0029] Openings 201 are provided above the inner walls on both sides of the cooling water tank 2, and the openings 201 face each other in pairs. Both ends of the pin 9 are inserted and slidably connected into the openings 201.

A pressing block 10 is arranged in the slot part 202, and a pull rod 11 and a spring 12 are arranged inside the pressing block 10. After the first guide roller 6 and the second guide roller 7 are installed according to the size of the drawn wire extruded by the injection molding extruder 1, one end of the pin column 9 is pressed by the pressing block 10 to make the first guide roller 6 and the second guide roller 7 stable. When the size of the drawn wire extruded by the injection molding extruder 1 changes, the pull rod 11 is pulled outside to contract the spring 12, and the pressing block 10 retracts into the slot part 202, so that the first guide roller 6 and the second guide roller 7 can be taken out. After replacement, the pull rod 11 is released to make the pressing block 10 press the upper part of one end of the pin column 9 again.
