Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0023] refer to Figure 1-3 , an extrusion die for the production of plastic sheaths, comprising a die body 1, a storage hopper 2 is fixedly connected to the top of the die body 1, and an outlet connected to the feed port of the die body 1 is provided on the inner bottom of the storage hopper 2 The inner diameter of the material outlet 3 and the storage hopper 2 gradually decreases from top to bottom, and the shape of the material outlet 3 is bucket-shaped, and the inner diameter of the material outlet 3 gradually decreases from top to bottom to ensure the efficiency of material discharge. The inside of the feed port 3 is slidingly connected with a plug 4 .

The invention discloses an extrusion die for the production of plastic sheaths, which comprises a die body, a storage hopper is fixedly connected to the top of the die body, and an inner bottom surface of the storage hopper communicates with a feed port of the die body The outlet of the outlet, the inside of the outlet is slidingly connected with a plug, the top of the plug is fixedly connected with a pull plate, the bottom of the pull plate is provided with an installation groove, and the inner top of the installation groove is fixedly connected with a reset spring, the bottom of the return spring is fixedly connected with the inner wall of the storage hopper. The invention has a reasonable structure, the movement of the filter net can stir and filter the material in the storage hopper, keep the activity of the material in the storage hopper, avoid the solidification of the material, the return spring pulls the pull plate to reset, and the plug is inserted into the inside of the discharge port to reseal the discharge. For the material port, because the power of the pulling motor is constant, the material flowing out each time is constant, which avoids material waste.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to an extrusion mold used for the production of plastic sheaths. Background technique [0002] Mold (mú jù), various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". [0003] The sheath is used for the outer insulation and protection of the terminal and is widely used in various electrical wire harnesses such as wires, electrical appliances, automobiles, motorcycles, air conditioners, washing machines, refrigerators, etc.; it has the...
