[0021] Example embodiments will now be described more fully with reference to the accompanying drawings.
[0022] The accompanying drawings are only schematic illustrations of the present disclosure. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted. It is understood that the proportions of the various components in the drawings do not constitute limitations of the present disclosure.
[0023] like Figure 1-6As shown, the embodiment of the present specification provides a push block 10 structure with a high-gloss surface 301, including a push block 10 body applied to the mold 20 for ejecting the shell product 30, the movable surface of the push block 10 includes a first inclined surface 101 adjacent to the top and a second inclined surface 102 adjacent to the bottom, a plane 103 is arranged between the first inclined surface 101 and the second inclined surface 102, a gentle slope is arranged at the junction of the first inclined surface 101 and the plane 103 and at the junction of the second inclined surface 102 and the plane 103, the inclination of the first inclined surface 101 is greater than the inclination of the second inclined surface 102, there is a single-sided gap between the first inclined surface 101 and the inclined surface of the rear mold core 201 of the mold 20, and there is no gap between the second inclined surface 102 and the rear mold core 201.
[0024] like Figure 2 The shell product 30 shown, such as the shell of a rice cooker, has a high gloss surface 301, which needs to be pushed out by a push block 10. In order to prevent the problem of the push block 10 being burned and the product surface oil seeping, the push block 10 as above is set. Among them, the slope of the first inclined surface 101 can be 8°, and the slope of the second inclined surface 102 can be 5°, ensuring that the second section of the inclined surface is a guide surface and a pipe surface when resetting. In addition, the unilateral gap of the first inclined surface 101 is less than the depth value of the exhaust groove of the product made of ABS rubber, such as the width of the unilateral gap is 0.01mm, which is less than the 0.03mm depth value of the exhaust groove of the product using ABS rubber, ensuring that the first inclined surface 101 does not contact the inclined surface of the rear mold core 201, and there will be no burning without friction, and there is also an exhaust function. Lubricating oil is provided between the second inclined surface 102 and the inclined surface of the rear mold core 201. Among them, during mass production, a thin layer of lubricating oil can be applied on the second inclined surface 102 to reduce the friction between it and the inclined surface of the rear mold core 201. Under the dual effects of the outward flow of the injection exhaust gas flow and the close fit between the plane 103 of the middle push block 10 and the plane 103 of the rear mold core 201, the lubricating oil will be prevented from seeping into the glue surface, thereby ensuring that the second inclined surface 102 has the functions of guiding and positioning when resetting, thereby meeting the normal demoulding and structural requirements of the shell product 30.
[0025] For ease of understanding, the demoulding process of the mold 20 is briefly described here. After the product is injection molded, the slider seat and the slider insert 202 surround the product. As the front mold and the rear mold separate, the cylinder drives the slider seat 203 away from the product, and the push block 10 pushes up to eject the product from the rear mold core 201.
[0026] Those skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and practicing the utility model disclosed herein. This application is intended to cover any variations, uses or adaptations of the present disclosure, which follow the general principles of the present disclosure and include common knowledge or customary technical means in the art that are not disclosed in the present disclosure.
