Secondary track change structure capable of preventing slider from descending due to gravity

Abstract

The invention provides a secondary track change structure capable of preventing a slider from descending due to gravity. The system comprises a slider mechanism, an oil cylinder, a guide block and a stop dog. The slider mechanism comprises a lower slider insert, an upper slider insert and a tunnel slider insert, wherein the upper slider insert is installed on the lower slider insert and fixed through a first screw, and the tunnel slider insert is arranged between the upper slider insert and the lower slider insert. The oil cylinder comprises an oil cylinder base installed on the lower slider insert. A first connection block is arranged at the lower end of the oil cylinder base and provided with a piston rod. The piston rod extends leftwards and is connected with a second connection block.The stop dog is arranged in a through hole, the lower end of the stop dog is connected with the guide block, and the guide block is provided with a guide rail. The secondary track change structure capable of preventing the slider from descending due to gravity is simple in structure, convenient and fast to use and long in service life, the situation that a side core collides with a mold cavity ofa mold core in the transportation process due to gravity can be effectively avoided, and the economic benefits are greatly increased.

Description

technical field [0001] The invention relates to a positioning mechanism of an injection mold, in particular to a secondary rail-changing structure that prevents the positioning from falling due to gravity. Background technique [0002] A plastic mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain complex-shaped parts. When processing some complex products, the positioning mechanism will be used in the injection mold. The positioning mechanism of the injection mold refers to those who can obtain side core pulling or side parting and reset action to get out of the product undercut, depression, etc. The position mechanism and the row mechanism are widely used in injection molds; when the injection mold is processed and needs to be transported to the customer, often the row mechanism will move back and forth due to grav...

Problems solved by technology

When processing some complex products, the positioning mechanism will be used in the injection mold. The positioning mechanism of the injection mold refers to those who can obtain side core pulling or side parting and reset action to get out of the product undercut, depression, etc. The position mechanism and the row mechanism are widely used in injection molds; when the injection mold is processed and needs to be transported to the customer, often the row mechanism will move back and forth due to gravity during the transportation project, and the side pull on the row mechanism When the core moves back and forth, it is easy to collide with the cavity of the mold core and cause damage to the cavity. At this time, it is necessary to design a secondary track structure to prevent the row position from falling due to gravity.
