Mould adjustable in bottom thickness of injection molded products

Abstract

The invention discloses a mould adjustable in bottom thickness of injection molded products. The mould comprises a lower mould plate, the top of the lower mould plate is fixedly connected to the bottom of a seal gasket, the top of the seal gasket is in lap joint with the bottom of an upper mould plate, a moving block internally sleeves the upper mould plate, each of left and right sides of the moving block is fixedly connected with one side of each of two sliders, each slider internally sleeves a slide groove in one side of the inner wall of the upper mould plate, and the bottom of each slideris movably connected with the bottom of the inner wall of the corresponding slide groove through a telescopic rod. By improvement of the upper mould plate, a pressure spring in each slide groove is matched with the corresponding telescopic rod to extrude the moving block to a standard position, and accordingly extrusion of a standard product can be realized by a mould core, the moving block can be extruded by a pressure block by rotating of an adjusting rod, and thus, the moving block pushes the mould core to move downwards. When injection molding slurry enters a mould groove, thickness reduction is realized under the extruding action of the mould core, and accordingly adjustment is realized.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a mold capable of adjusting the thickness of the bottom of an injection molded product. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, molds are tools used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material, known as the "mother of industry". [0003] All the values ​​of the commonly used molds are fixed in use, such as the length, width and thickness of the injection molded products are immutable, and only one type of product can be injected, so one type of mold cannot squeeze Extrude p...
