Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold with an ejection mechanism. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by methods such as injection molding, blow molding, extrusion, die-casting, forging, smelting and stamping. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. The mold is generally composed of an upper mold and a lower mold, and mold cavities are opened inside the upper and lower molds.

[0003] For example, publication number CN215472466 discloses a mold with a self-locking function and an ejection mechanism. The device is provided with an ejection assembly on a base. After the product is formed between an upper mold and a lower mold, the upper mold is disassembled, and the product in the lower mold can be automatically ejected by the ejection assembly.

[0004] However, the practicality of the ejection assembly is poor when in use. The device can only eject the product through the cooperation of the cylinder and the ejector plate during ejection, and the product cannot be fixed after ejection, which causes the product to easily fall on the surface of the bottom plate and affects the use, thereby reducing the practicality of the device. In view of this, we propose a mold with an ejection mechanism. Utility Model Content

[0025] In one embodiment of the utility model, a protective structure 3 is provided to facilitate rapid ejection of the product and prevent it from tipping over and affecting its use. When in use, the movable mold and the fixed mold 6 work together to process the mold. The electric push rod 5 model is CAHB-10. By controlling the extension and retraction of the output shaft of the electric push rod 5 to drive the movable mold to move up and down, the user can pour the product raw materials into the fixed mold 6, and then control the output shaft of the electric push rod 5 to move downward to drive the movable mold and the fixed mold 6 to close the mold, and then wait for the mold processing to be completed. After the processing is completed, the user can control the output shaft of the electric push rod 5 to move upward to drive the movable mold and the fixed mold 6 to open the mold. At this time, the user can start the hydraulic rod 32 to work, and the output shaft of the hydraulic rod 32 moves upward to drive the connecting plate 33 to The connecting plate 33 moves, and then drives the two groups of first tooth plates 34 of its side walls to move upward.

The rotating gear 37 rotates and drives the second tooth plate 38 meshing with it to move downward. The second tooth plate 38 moves downward and drives the connecting rod 311 to move. The movement of the connecting rod 311 drives the slider 310 hinged thereto to move inside the slide groove 39. The movement of the slider 310 drives the two groups of support plates 312 to move relatively to support and fix the two sides of the product, thereby improving the practicality of the device.

[0026] Please continue reading Figure 1-Figure 5The moving structure 4 includes two groups of positioning cylinders 41 fixedly installed on the upper end of the slider 310, the inner wall of the positioning cylinder 41 is slidably connected with a moving rod 42, one end of the moving rod 42 is fixedly installed with a limiting block 43, and the other end of the moving rod 42 is fixedly connected to the side wall of the support plate 312. A return spring 44 is arranged on the surface of the moving rod 42, one end of the return spring 44 is fixedly connected to the side wall of the positioning cylinder 41, and the other end of the return spring 44 is fixedly connected to the side wall of the support plate 312. The rotating gear 37 is in a meshing state with the first tooth plate 34 and the second tooth plate 38. The two ends of the connecting plate 33 are respectively fixedly connected to the side walls of the two groups of first tooth plates 34, and a stripping plate 9 is fixedly installed on the upper end of the first tooth plate 34. The return spring 44 is fixedly connected to the side wall of the supporting plate 312. One end of the spring 44 is fixedly connected to the side wall of the positioning cylinder 41, and the other end of the return spring 44 is fixedly connected to the side wall of the support plate 312. By setting up the movable structure 4, it is convenient to better support and fix the mold products of different widths. The two sides of the product are fixed by two groups of movable support plates 312. In order to better fit the side wall of the product, when the support plate 312 contacts the side wall of the product, the support plate 312 can also move the moving rod 42 of the side wall due to extrusion. At the same time, the support plate 312 will also squeeze the return spring 44, so that the two groups of support plates 312 can better support and fix the mold products of different widths.

[0027] During operation, the user first fixes the workbench 1 stably, then pours the product raw materials into the fixed mold 6, and then controls the output shaft of the electric push rod 5 to move downward to drive the movable mold and the fixed mold 6 to close the mold, and then waits for the mold processing to be completed. After completion, the mold is opened, and then the hydraulic rod 32 is started to work. The output shaft of the hydraulic rod 32 moves upward to drive the connecting plate 33 to move. The connecting plate 33 moves and then drives the two groups of first tooth plates 34 on its side wall to move upward. The first tooth plates 34 move upward to drive the stripping plate 9 to move upward to contact the bottom plate 8 and drive it to move upward, so that the bottom plate 8 drives the product to move upward to complete the demoulding work, and when the first tooth plate 34 moves upward, it also drives the rotating gear 37 to rotate on the surface of the rotating rod 36 The rotating gear 37 rotates and drives the second tooth plate 38 meshing with it to move downward, and the second tooth plate 38 moves downward to drive the connecting rod 311 to move. The movement of the connecting rod 311 drives the slider 310 hinged to it to move inside the slide groove 39. The movement of the slider 310 drives the two groups of support plates 312 to move relatively to support and fix the two sides of the product. After the support plate 312 contacts the side wall of the product, the support plate 312 can also move the moving rod 42 of the side wall due to the extrusion. At the same time, the support plate 312 will also squeeze the reset spring 44, so that the two groups of support plates 312 can better support and fix mold products of different widths, thereby further improving the practicality of the device.
