Description

Technical Field

[0001] The utility model relates to the technical field of rotational molding molds, in particular to a device for quickly disassembling and assembling embedded parts. Background Art

[0002] Moulds are various molds and tools used in industrial production to obtain the required products by methods such as rotational moulding, injection moulding, blow moulding, extrusion, die casting or forging, smelting, stamping, etc. In short, moulds are tools used to make moulded objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the moulded material, and is known as the "mother of industry".

[0003] In the process of rotational molding, when the product needs to be embedded with an insert, the original technology is to drill holes on the mold to install a toothed sleeve, and to embed the insert by cooperating with a screw and a nut. In this method, the screw is mostly fixed and cannot move. After the insert is embedded in the mold product, during the cooling process, the product will retract inward, thereby pulling the insert back. Due to the inability to move, the insert will be offset or the rotational molded product will be pulled to cause the product to deform, affecting the product quality or causing the product to be scrapped. The above-mentioned people invented a fixing device composed of a sleeve and a spring screw. Although this structure solves the above problems However, it still has the following problems: since the elastic ring has a rebound force, it will rebound and reset the spring-loaded screw. Due to the positioning and fixing function, when a new insert needs to be installed, the entire insert needs to be installed on the fixing device so that the end of the screw is flush with the end of the insert, or the end of the screw slightly protrudes from the end of the insert. However, the thread of the insert is deep, and it takes a long time to install the insert, resulting in low work efficiency. If the installation depth of the insert is insufficient, the end of the screw cannot be flush with the end of the insert, causing the material flow to cover the thread, resulting in the insert being unable to be used normally.

[0004] The Chinese patent proposes a through-hole insert fixture (patent number CN202321512938.2) to solve the above technical problems. However, an annular limit block is provided at the bottom of the fixing seat. This structure protrudes from the mold surface, causing a dent on the surface of the rotationally molded part after rotational molding is completed, thereby causing the insert to be sunken into the product surface, resulting in reduced product precision and errors when the product is fixed on the machine, which in turn leads to a decrease in the product pass rate.
