Abstract
Description
Technical Field
[0001] This utility model relates to the field of molds, and in particular to an air conditioner electrical cover mold. Background Technology
[0002] A mold is a set of molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects; this tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the shaping of objects by changing the physical state of the material being molded.
[0003] A mold is a tool used to shape a blank into a part with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics, and other products. A mold has a specific contour or internal cavity shape. Using a contour shape with cutting edges allows the blank to be separated according to the contour line (blanking). Using an internal cavity shape allows the blank to obtain a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a punch and a die), which can be separated and joined. When separated, the part is removed; when joined, the blank is injected into the mold cavity to form the part.
[0004] The undercut area of the air conditioner cover typically uses a hydraulic cylinder-driven angled core-pulling structure for demolding. However, the hydraulic cylinder drive has a slow response speed and delayed mold opening and closing, extending the overall cycle time. The hydraulic cylinder and slider must open the mold in a strict sequence; if the timing is not controlled correctly, it can easily lead to slider collisions or mold compression accidents. When the injection pressure increases, the hydraulic cylinder's clamping force is difficult to match, easily causing gaps (dimensional misalignment) and flash (overflow) at the undercut, resulting in a lower yield rate. The hydraulic cylinder system also increases mold manufacturing costs and maintenance complexity. Therefore, the existing mold structure suffers from problems such as long molding cycles, high collision risks, insufficient clamping force, and high costs.
[0005] Chinese patent CN111251559A discloses an air conditioner frame mold, comprising, from top to bottom, an upper fixed plate, a diversion plate, an A plate, a B plate, an ejector pin assembly, and a lower fixed plate. The B plate contains a demolding slider assembly, which includes an inclined guide post, a first slider, and a second slider. The first slider is attached to the barbed edge of the side of the air conditioner frame, and the second slider is attached to the barbed edge of the drainage hole structure of the air conditioner frame. The inclined guide post passes through the first slider and controls its lateral movement. The lower end of the second slider is connected to a hydraulic cylinder, and the second slider is slidably mounted on an inclined surface. During mold closing, the tops of the first and second sliders engage to form a locking structure. This patent relies on hydraulic cylinder drive, resulting in slow response and complex timing control. Utility Model Content

[0068] S2. Driven by two hydraulic cylinders on the ejector plate, the upper and lower ejector plates retract. When the upper and lower ejector plates are in place, the injection molding machine closes the mold.
[0069] The top of the first inclined guide post 2 is fixed below plate A 1. The first inclined guide post 2 drives the second slider 6 to slide horizontally to the right along plate B 8. The guide block 5 fixed on the second slider 6 lifts the first slider 4 to slide horizontally upward.
[0070] When the injection molding machine finishes closing the mold, the second slider 6 and the first slider 4 are both reset and stop moving, completing one production cycle.
