Description
无导向固定卸料式落料模具
技术领域
[0001] 本发明涉及模具技术领域，特别是无导向固定卸料式落料模具。
背景技术
[0002] 改革开放以来，随着国民经济的高速发展，市场对模具的需求量不断增长。近年来，模具工业一直以15%左右的增长速度快速发展，模具工业企业的所有制成分也发生了巨大变化，除了国有专业模具厂外，集体、合资、独资和私营也得到了快速发展。近年许多模具企业加大了用于技术进步的投资力度，将技术进步视为企业发展的重要动力。一些国内模具企业已普及了二维CAD,并陆续开始使用UG、Pro/Engineer、1-DEAS、Euclid_IS等国际通用软件。
[0003] 模具是现代工业生产中重要的工艺装备之一，在铸造、锻造、冲压、塑料、橡胶、玻璃、粉末冶金、陶瓷等生产行业中得到广泛应用。近年来，我国的模具工业也有了较大的发展，模具制造工艺和生产装备智能化程度越来越高，极大地提高了模具的制造精度、质量和
生产率。
[0004] 现有的钣金冲压件主要是利用模具完成各种形状的加工，落料模具是冷冲压过程中最常见的一种模具，落料时用压力机推动上模进行冲压落料，传统的落料模结构复杂，操作技术水平要求较高，凹模与凸模的配合精度难以控制，由于压力过大，料板很容易损坏，落料件的废次品率高，而且容易造成凹模与凸模磨损严重，维护成本高。
发明内容
[0005] 本发明的目的在于克服现有技术的缺点，提供一种操作简单、产品质量高和维护成本低的无导向固定卸料式落料模具。
[0006] 本发明的目的通过以下技术方案来实现:无导向固定卸料式落料模具，它包括上模座、凸模、下模座和凹模，上模座上方中心位置连接有模柄，模柄与外部压力机相连，凸模通过螺钉固定在上模座的下方，并通过至少两颗定位销定位；下模座的上方依次从下至上固定安装有凹模和卸料板，凹模上设置有与凸模相适配的落料孔。
[0007] 所述的凹模的后侧还设置有挡料销。
[0008] 所述的挡料销为回带式挡料销。
[0009] 本发明具有以下优点:
1、本发明的结构简单，在凹模的后侧设置挡料销，送料方向的定距通过挡料销完成，降低操作难度，对操作人员的技术水平要求较低。
[0010] 2、凸模与上模座之间通过双定位销进行定位，凹模和卸料板也固定在下模座上，凹模与凸模配合精准，落料精度高，产品的质量好。
[0011] 3、凹模与凸模配合，凹模与凸模摩擦小，凹模与凸模不易损坏，大幅度降低了模具的维护成本。附图说明
[0012] 图1为本发明的结构示意图；
图2为下模座与凹模配合的俯视结构示意图；
图3为图2中A-A剖视结构示意图；
图中:1_上模座，2-凸模，3-下模座，4-卸料板，5-凹模，6-挡料销，7-落料孔，8-模柄。
具体实施方式
[0013] 下面结合附图对本发明做进一步的描述，但本发明的保护范围不局限于以下所述。
[0014] 如图1所示，无导向固定卸料式落料模具，它包括上模座1、凸模2、下模座3和凹模5，上模座I上方中心位置连接有模柄8，模柄8与外部压力机相连，凸模2通过螺钉固定在上模座I的下方，并通过至少两颗定位销定位；下模座3的上方依次从下至上固定安装有凹模5和卸料板4，凹模5上设置有与凸模2相适配的落料孔7。
[0015] 所述的凹模4的后侧还设置有挡料销6。
[0016] 所述的挡料销6为回带式挡料销。
[0017] 本发明的工作过程如下:凸模2和模柄8固定连接成为一体结构，并用定位销定位。1旲柄8与外部压力机连接,在放料之如，|旲柄8提升至最闻点，凸|旲2的最低点闻于凹模5的最高点，将毛坯料放在凹模5与卸料板4之间，毛坯料的前端顶在挡料销6上，送料方向的定距由挡料销6完成，毛坯料固定后，模柄8带动凸模2下移，使凹模5与凸模2配合，完成落料，落料件从落料孔7向下落料，模柄8带动凸模2上移，毛坯料被卸料板4挡住，凸模2与毛坯料脱离。
