Injection mold for tool post

Abstract

The invention discloses an injection mold for a tool post, which comprises a moving mold plate, a fixed mold plate, an axially positioning oil cylinder for axially positioning an inner thread type core sheath, a radially positioning oil cylinder for radially positioning the inner thread type core sheath, and a mold insert oil cylinder, wherein the inside of the fixed mold plate can be movably provided with the inner thread type core sheath, the outer wall of the inner thread type core sheath is meshed with a gear, the gear is meshed with a rack, and the rack is connected with an output shaft of a rack oil cylinder which drives the rack to do reciprocating linear motion; an output shaft of the axially positioning oil cylinder and an output shaft of the radially positioning oil cylinder arealigned the inner thread type core sheath; the moving mold plate is embedded with a mold insert used for molding a mounting hole of an inching switch, and an output shaft of the mold insert oil cylinder is connected with the mold insert; and a mold cavity is enclosed by the fixed mold plate, the inner thread type core sheath, the moving mold plate and the mold insert. The invention has the advantages of providing an injection mold used for molding a tool post of which an inner thread is provided with a mounting hole, and enabling the injection mold to mold the tool post of which the inner thread is provided with the mounting hole.

Description

(1) Technical field [0001] The invention relates to a knife table injection mold. (2) Background technology [0002] Such as figure 1 Shown is a schematic diagram of the structure of the knife table, which is mainly used in juicers and cooking machines to fix the knife holder. The traditional knife table is not equipped with micro switches, in order to facilitate the control, such as figure 1 As shown, a mounting hole for installing a micro switch is opened on the internal thread of the tool table, and the operation of the machine can be easily controlled by an empty switch when the micro switch is installed in the mounting hole. After the installation hole is opened on the internal thread of the knife table, the internal thread has the requirement of starting teeth, so the design and manufacturing requirements of the mold are more difficult. At present, there is no injection mold for forming the knife table with this structure. (3) Contents of the invention [0003] In...
