Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a quick demolding device for plastic molds. Background Technology

[0002] Molds are various shapes 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, molds are tools used to create shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the shaping of objects by changing the physical state of the material being molded. Often called the "mother of industry," molds are tools that transform blanks into parts with specific shapes and dimensions under external force. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and the pressing of engineering plastics, rubber, ceramics, and other products. In plastic or injection molding, molds have specific contours or internal cavity shapes. The contour shape with cutting edges can separate the blank according to the contour line (punching), and the internal cavity shape can give the blank a corresponding three-dimensional shape. Molds generally consist of two parts: a moving mold and a fixed mold (or a punch and a die). The two parts can be separated or joined together. When separated, the part is removed, and when joined together, the blank is injected into the mold cavity for forming. Molds are precision tools with complex shapes. They withstand the expansion force of the blank and have high requirements for structural strength, rigidity, surface hardness, surface roughness, and machining accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.

[0033] Reference Figures 1-4 A quick demolding device for plastic molds includes a base 1, a limit component 2 provided on the upper surface of the base 1, and an extrusion component 3 provided on the bottom of the base 1.

[0034] The limiting component 2 includes a mold 200 fixedly mounted on a base 1. A touch switch 201 is fixedly mounted on the inner bottom wall of the mold 200.

The limiting ring 203 has a rod hole through which the electric push rod 206 passes, and the inner wall of the rod hole is slidably connected to the surface of the electric push rod 206. The rod hole facilitates the passage of the electric push rod 206 during use, thereby facilitating its installation and positioning. The design improves the efficiency of the device. A screw 207 is inserted into one side of the vertical plate 205, and one end of the screw 207 is threadedly connected to one side of the mounting block 204. A screw hole is provided on the vertical plate 205 for the screw 207 to pass through, and the screw hole is threadedly connected to the screw 207. A rotating block is fixedly installed at one end of the screw 207, and a hexagonal hole is provided on one side of the rotating block. The screw 207 facilitates the installation and positioning of the vertical plate 205 during use, thus facilitating the installation operation and subsequent disassembly and assembly, improving the ease of use of the device. The limiting component 2 facilitates the limiting and pressing operation during use, making it easy to position the device and preventing it from loosening during use, thus improving the efficiency of the device and facilitating subsequent operations.

[0035] The extrusion assembly 3 includes a cylinder 300 fixedly mounted on a base 1. The bottom of the cylinder 300 is fixedly connected to a horizontal plate 301. A lead screw 302 is inserted into the horizontal plate 301. The top of the lead screw 302 is rotatably connected to an extrusion rod 303 via a bearing. The top of the extrusion rod 303 passes through the base 1 and the mold 200 sequentially and extends into the interior of the mold 200. The top of the extrusion rod 303 is fixedly connected to the bottom of the partition plate 202. Both the base 1 and the mold 200 have circular holes for the extrusion rod 303 to pass through. The inner wall of the circular hole is slidably connected to the surface of the extrusion rod 303. The circular holes facilitate the passage of the extrusion rod 303 during use, improving its passability and also making it easier to pass through. For ease of use, the horizontal plate 301 has a threaded hole for the lead screw 302 to pass through, and the threaded hole is threadedly connected to the lead screw 302.

[0036] Reference Figure 1 In a preferred embodiment, support components 4 are provided on both sides of the base 1. The support components 4 include support legs 400 fixedly installed on both sides of the base 1. Threaded rods 401 are inserted into the bottom of the support legs 400. The support components 4 facilitate the adjustment of the support height of the base 1 during use, thereby facilitating the placement of the device and improving its ease of use. The bottom of the threaded rods 401 is rotatably connected to a support plate 402 via bearings. The support plate 402 has mounting holes, which are oblong holes. The lower surface of the support plate 402 has anti-slip textures. The support plate 402 facilitates the installation and positioning of the device during use, thereby facilitating the positioning operation of the device and improving its ease of use.

[0037] Working principle: When demolding is required, the lead screw 302 is rotated, which in turn causes the partition 202 on the extrusion rod 303 to move upward, thereby separating the bottom of the partition 202 from the touch switch 201. At this time, the touch switch 201 controls the electric push rod 206 to retract, and then one end of the electric push rod 206 separates from one side of the mold 200, which facilitates the loosening of the top of the mold 200 during use and avoids the parts limiting the top of the mold 200. Then, the top of the lead screw 302 drives the extrusion rod 303 to move upward, thereby causing the partition 202 to extrude the object inside the mold 200. This facilitates demolding operations during use and improves the demolding speed of the device.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
