Description

Technical Field

[0001] The utility model relates to the technical field of plastic rattan molding, in particular to a plastic rattan molding mold. Background Art

[0002] Plastic rattan refers to outdoor furniture made of plastic rattan. Common outdoor rattan furniture products are mainly PE rattan furniture. Plastic rattan has excellent wear resistance, good low-temperature impact resistance, self-lubrication, non-toxicity, water resistance, chemical resistance, and heat resistance better than general PE. The disadvantages are low heat resistance, poor processing and forming properties, and the outer surface hardness, rigidity, and creep resistance are not as good as general engineering plastics. The expansion coefficient is relatively large. Plastic rattan is generally formed through extrusion.

[0003] For example, a Chinese patent (CN212312700U) discloses a plastic woven rattan molding device, including a conveying pipe, a mold is fixedly connected to one side outer wall of the conveying pipe, and an extrusion hole is opened on the outer wall of the mold, a through hole is opened on the outer wall of the mold located outside the extrusion hole, and a heat conducting plate is inserted into the inner wall of the through hole, a cooling cavity is opened inside the mold located outside the heat conducting plate, and the outer walls of the mold located above and below the cooling cavity are fixedly connected to a coolant infusion pipe. The utility model is provided with a heat conducting plate and a coolant infusion pipe, a through hole is opened on the outer side of the extrusion hole of the mold, a heat conducting plate is installed on the inner wall of the through hole, and a cooling cavity is opened on the inner wall near the outer side of the extrusion hole, and the plastic rattan near the outer side is cooled and plasticized in the extrusion hole. The part of the extrusion hole near the inner side of the conveying pipe cannot change its shape because it is in the extrusion hole, so that the shape of the rattan after plasticization is the same as that of the rattan before plasticization, thereby improving the molding effect of the rattan molding device.

[0004] The above scheme also has the following technical deficiencies: the above scheme is not convenient for making plastic rattans of different sizes; since the inner diameter of the mold in the above scheme is fixed, only one size of plastic rattan can be made when the plastic rattan is processed and formed; if rattans of other sizes need to be made, a device with molds of other sizes needs to be used for processing; based on this, a plastic rattan forming mold is proposed.
