An injection mold for forming holes by means of an auxiliary device

Abstract

The invention discloses an injection mold for forming a hole by means of an auxiliary device, and belongs to the field of molds. The injection mold comprises a movable mold and a fixed mold fitted with the movable mold, wherein the auxiliary device for forming the hole is arranged on the movable mold, and comprises an oil cylinder; the oil cylinder comprises a first piston rod, and further comprises a tilted chute I, a tilted chute II, a linkage change-over block, a guide block and a second piston rod; the tilted chute I is arranged at the tail end of the first piston rod, and communicates with the tilted chute II via the linkage change-over block; the guide block sleeves the linkage change-over block; and the second piston rod is arranged on the tilted chute II. The injection mold is mainly used for fast switching between non-hole machining and porous machining by adjusting extension and withdrawn of the piston rods without producing another injection mold, and has the advantages that the production cost is low, and the running is stable and accurate; and moreover, the mounting positions of output mechanisms are not limited by space, that is, impact of distance on forming of a hole at a specific position of an injection product is avoided.

Description

technical field [0001] The invention belongs to the field of molds, and more specifically relates to an injection mold for forming holes by means of an auxiliary device. Background technique [0002] At present, the injection molding products in the prior art are processed and formed by injection molds. In order to cooperate with the use of other products, the holes on the injection molding products have different functions, so that the injection molding products have various states, and the injection molding products are required to have holes or no holes somewhere. There are many states of holes, so as the position of the holes on the injection molding product changes, the original injection mold is limited by its own structure and cannot meet the production needs of the existing injection molding products. However, in order to save costs and avoid reprocessing the injection mold, Usually, during the injection molding manufacturing process of injection molding products, an...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the need to remake the mold in the prior art to realize the switch between the hole processing and the non-hole processing of the injection molding product structure. At the same time, because the installation position of the power output mechanism is affected by the space, the specific position on the injection molding product cannot be completed In order to solve the problems of forming holes, etc., an injection mold for forming holes with the help of auxiliary devices is provided. Using the technical solution of the present invention, the fast switching between non-hole processing and hole processing can be realized by adjusting the extension and extension of the piston rod. According to the different states of injection molding products, the injection molds can be remade to save costs, and the auxiliary device of the molding hole runs smoothly and accurately, which can prolong its service life and improve product quality; at the same time, the installation position of these power output mechanisms can be improved through the translation of force Unaffected by space, the molding of holes at specific positions on injection molded products is not affected by distance
