Description

一种塑胶模具的斜顶结构A sloped top structure of a plastic mold

技术领域technical field

本实用新型属于磨具技术领域,具体涉及一种塑胶模具的斜顶结构。The utility model belongs to the technical field of abrasive tools, in particular to a slanted top structure of a plastic mould.

背景技术Background technique

模具是指工业生产上用以注塑、吹塑、挤出、压铸或锻压成型、冶炼、冲压等方法得到所需产品的各种模子和工具。简而言之,模具是用来制作成型物品的工具,这种工具由各种零件构成,不同的模具由不同的零件构成。它主要通过所成型材料物理状态的改变来实现物品外形的加工。素有“工业之母”的称号,在外力作用下使坯料成为有特定形状和尺寸的制件的工具。广泛用于冲裁、模锻、冷镦、挤压、粉末冶金件压制、压力铸造,以及工程塑料、橡胶、陶瓷等制品的压塑或注塑的成形加工中。模具具有特定的轮廓或内腔形状,应用具有刃口的轮廓形状可以使坯料按轮廓线形状发生分离(冲裁)。应用内腔形状可使坯料获得相应的立体形状。模具一般包括动模和定模(或凸模和凹模)两个部分,二者可分可合。分开时取出制件,合拢时使坯料注入模具型腔成形。模具是精密工具,形状复杂,承受坯料的胀力,对结构强度、刚度、表面硬度、表面粗糙度和加工精度都有较高要求,模具生产的发展水平是机械制造水平的重要标志之一。Mold refers to 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, a mold is a tool used to make shaped 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 article through the change of the physical state of the formed material. Known as the "mother of industry", it is a tool for turning blanks into workpieces with specific shapes and sizes under the action of external forces. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing.

模具斜顶又名斜梢,斜顶是以港资模具厂为主的珠三角地区模具行业的惯用说法,是模具设计中用来成形产品内部倒钩的机构,适用于比较简单的倒钩情况。The inclined top of the mold is also known as the inclined tip. The inclined top is a common saying in the mold industry in the Pearl River Delta region dominated by Hong Kong-funded mold factories. It is a mechanism used to shape the internal barbs of the product in mold design. It is suitable for relatively simple barbs. .

然而现有的塑胶模具的斜顶结构在使用的过程中仍然存在一些不合理的因素,现有的塑胶模具的斜顶结构在使用时,且强度不够,导致经常损坏,使用起来不是特别的方便。However, there are still some unreasonable factors in the use of the existing sloping roof structure of the plastic mold. The slanting roof structure of the existing plastic mold is not strong enough when used, which leads to frequent damage and is not particularly convenient to use. .
