The invention discloses a casting mold for a part with forward and backward threaded holes. The casting mold comprises a movable mold and a stationary mold. The movable mold comprises a J-shaped support. A first shaft is arranged on a transverse plate of the support, wherein the first shaft can rotate but cannot move axially and is perpendicular to the transverse plate. The upper end of the firstshaft is provided with a driving bevel gear, and the lower end of the first shaft is provided with a cylindrical gear. A fixing bracket of the stationary mold is fixedly arranged on a support plate and located at the outer side of the support and is parallel with two plates of the support in a corresponding manner. A transverse plate of the fixing bracket is perpendicularly and fixedly connected with the support plate, and the plane where the fixing bracket is located is perpendicular to the support plate. The free end of a horizontal plate of the support is connected with a hydraulic rod which drives the horizontal plate to perform reciprocating linear motion so that when the hydraulic rod pushes the support to be closely attached to a vertical plate of the fixing bracket, a cylindrical mold cavity can be combined with a mold hole to form a cavity for the part needing to be cast. When the hydraulic rod retracts, the cylindrical gear is engaged with a rack to achieve transmission. Themold is extremely high in molding efficiency; the procedures are implemented automatically and continuously; and the obtained part is good in molding quality.
Description
technical field [0001] The invention belongs to the technical field of casting molding, and in particular relates to a casting molding mold for parts with two kinds of screw holes. Background technique [0002] In daily production, some parts have threaded holes with general precision, and these threaded holes are parallel to each other and rotate in opposite directions, such as figure 1 A part shown has a first threaded hole 151, a rib plate 152, a second threaded hole 153, and a conical protrusion 154. During manufacturing, the part is often first cast into a blank, and then the machine tool is used for cutting and machining. Tapping the thread, the process is complicated and the efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a casting mold for parts with positive and negative threaded holes, which effectively solves the technical problems of complex process and low efficiency of the existing parts with threaded h...
