Device for forming plastic mold with embedded nuts and method

Abstract

The invention discloses a device for forming a plastic mold with embedded nuts and a method. The device for forming the plastic mold with the embedded nuts comprises a base and a top board arranged above the base, wherein supporting boards connected with two ends of the base are symmetrically arranged at two sides of the lower end of the top board, a lower mold block is arranged at the upper end of the base, an upper mold block is arranged over the lower mold block, an injection molding cavity used for injection molding is formed between the lower mold block and the upper mold block, cooling cavities used for cooling are formed in the upper mold block and the lower mold block, a middle position of the upper end of the upper mold block is connected with the lower end of a traction rod, the upper end of the traction rod is connected with an output end of a lifting cylinder, and the lifting cylinder is fixed onto the top board through a bolt. According to the device for forming the plastic mold with the embedded nuts and the method, design is conducted for defects of an existing device, nut blocks A and the injection mold can be integrated, a user does not need to be worried about the problem of the size of the mold, and temperature interval detection can be conducted on the nut blocks A and the injection mold, so that the problem of mold deformation caused by excessively-large temperature difference is avoided, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a plastic mold molding device and method for inserting nuts. Background technique [0002] At present, some injection molding products need to embed nuts in the product due to the characteristics of their own structure. The big problem we face. At present, the industry generally uses manual or robotic hands to perform nut implantation operations. Due to the high mold opening temperature and certain dangers, the manual implantation of nuts is inefficient and unstable in quality; the use of robotic arm implantation will increase Equipment development costs, and because some molds have a small opening distance, it is difficult for the manipulator to perform implantation between the upper and lower molds. [0003] In view of the above problems, the patent with the existing patent notification number CN111037845A discloses a nut embedded in the injection mold. The device e...

Problems solved by technology

At present, the industry generally uses manual or robotic hands to perform nut implantation operations. Due to the high mold opening temperature and certain dangers, the manual implantation of nuts is inefficient and unstable in quality; the use of robotic arm implantation will increase Equipment development costs, and because some molds have a small opening distance, it is difficult for the manipulator to perform implantation operations between the upper and lower molds

[0003] In view of the above problems, the patent with the existing patent notification number CN111037845A discloses a nut embedded in the injection mold. The device embeds the nut after the mold is formed. This embedding method will destroy the original structure of the mold to some extent, which is not conducive to improving the processing quality of the mold.
