技术领域: Technical field:
本发明涉及塑胶产品水口加工设备技术领域,特指塑胶产品软硬胶水口二次冲切设备。The invention relates to the technical field of processing equipment for nozzles of plastic products, in particular to secondary punching equipment for nozzles of hard and soft plastic products.
背景技术: Background technique:
随着有机材料在人们日常生活中的应用越来越多,塑胶材料作为常用的有机材料,在人们生活中已经广泛应用。常用的塑胶产品通常采用注塑工艺制成,在注塑时,产品上的进胶口即为行业中所称的水口,为了保证产品在设计上能有效的出模,并且出模时顶出顺畅,通常在保证产品不变形前提下采用多个进胶口同时进胶的方式制造,这样就产生一个问题,即是产品成型过程中会在产品结构设计上造成水口较多,通常的产品为一模几穴型。产品成型后,需要将水口去掉,目前加工产品水口时,通常采用的做法是人工用剪钳剪、用刀片削,或用冲切设备自动冲切。With the increasing application of organic materials in people's daily life, plastic materials, as commonly used organic materials, have been widely used in people's lives. Commonly used plastic products are usually made by injection molding process. During injection molding, the plastic inlet on the product is called the nozzle in the industry. In order to ensure that the product can be effectively released from the mold in design, and the ejection is smooth when the mold is released, Usually, under the premise of ensuring that the product does not deform, it is manufactured by using multiple glue inlets to feed glue at the same time. This will cause a problem, that is, there will be more nozzles in the product structure design during the product molding process. The usual product is a mold. A few holes. After the product is formed, the nozzle needs to be removed. At present, when processing the product nozzle, the usual method is to manually cut it with scissors, cut it with a blade, or automatically punch it with punching equipment.
现有的加工塑胶产品水口的冲切设备一般包括有冲切模具和驱动冲切模具动作的驱动装置,冲切模具包括相互配合的上模和下模,下模上对应于产品水口位置开有与产品水口形状相吻合的水口孔,各个水口孔之间通过导槽相互连通,上模上对应于水口孔位置固定安装有与水口孔形状相吻合的冲针,利用这种冲切设备可以一次性冲切掉多个水口。用现有的塑胶产品水口冲切设备同时冲切软硬胶水口时,由于硬胶流道和软胶流道成型时的缩水率差别很大,这使得该类产品模架上各个产品的各个水口的位置尺寸很不准确,这导致了冲切出来的产品均存在切伤和残留水口高的现象,冲切效果差,因而,现有的塑胶产品水口冲切设备不能用来冲切同时带有软硬胶水口的塑胶产品,所以带有软硬胶水口的塑胶产品一般都是通过人工加工切掉水口,浪费人力,生产效率低,生产成本高。Existing punching equipment for processing plastic product nozzles generally includes a punching die and a driving device for driving the punching die. The punching die includes an upper die and a lower die that cooperate with each other. The nozzle holes that match the shape of the nozzle holes of the product are connected to each other through guide grooves. The punching needles that match the shape of the nozzle holes are fixedly installed on the upper die. This punching equipment can be used at one time Sex punching cuts off multiple spouts. When the existing nozzle punching equipment for plastic products is used to punch the soft and hard glue nozzles at the same time, because the shrinkage rate of the hard rubber runner and the soft rubber runner is very different, this makes each product on the mold base of this type of product The position and size of the nozzle is very inaccurate, which leads to the phenomenon of cuts and high residual nozzles in the punched products, and the punching effect is poor. Therefore, the existing nozzle punching equipment for plastic products cannot be used for punching and cutting at the same time. There are plastic products with soft and hard glue nozzles, so the plastic products with soft and hard glue nozzles are generally cut off by manual processing, which wastes manpower, low production efficiency, and high production costs.

Nozzle hole 23, punching soft rubber bottom mold 22 is provided with more than one blanking hole 24 corresponding to the plastic product, lower mold 2 is provided with lower knife 5 around nozzle hole 23 and blanking hole 24, upper mold 3 corresponds to An upper knife 6 cooperating with the lower knife 5 is fixed at the position of the nozzle hole 23 and the blanking hole 24 . The lower knife 5 includes a first lower knife 51 and a second lower knife 52, and the upper knife 6 includes a first upper knife 61 and a second upper knife 62. The first lower knife 51 and the first upper knife 61 are connected to the nozzle hole 23. Cooperate, the second lower knife 52 and the second upper knife 62 cooperate with the blanking hole 24 .
驱动装置4包括有固定在底座1上的支架41、固定在支架41上的气缸42、位于上模3上方的升降板43,气缸42的输出端朝下并连接升降板43,上模3固定安装在升降板43上,以气缸42作为动力源反应速度快,控制方便。底座1上竖向设有导向杆44,升降板43滑动连接在导向杆44上,使得升降板43运动顺畅、平稳。The driving device 4 includes a bracket 41 fixed on the base 1, a cylinder 42 fixed on the bracket 41, a lifting plate 43 above the upper mold 3, the output end of the cylinder 42 is downward and connected to the lifting plate 43, and the upper mold 3 is fixed. Installed on the lifting plate 43, with the cylinder 42 as the power source, the response speed is fast and the control is convenient. The base 1 is vertically provided with a guide rod 44, and the lifting plate 43 is slidably connected to the guide rod 44, so that the lifting plate 43 moves smoothly and steadily.
底座1的侧面设有延伸至下模2下方的分开式落料盒7,用于盛放冲切掉的软、硬胶水口,分开式落料盒7中设有两个落料区,分别用于盛放软胶水口和硬胶水口。水口孔23及落料孔24贯穿下模2顶部和底部,使得冲切掉的软、硬胶水口可直接掉落在分开式落料盒7中。The side of the base 1 is provided with a separate blanking box 7 extending to the bottom of the lower mold 2, which is used to hold the punched soft and hard glue nozzles. The separate blanking box 7 is provided with two blanking areas, respectively It is used to hold the soft glue nozzle and the hard glue nozzle. The nozzle hole 23 and the blanking hole 24 run through the top and the bottom of the lower mold 2, so that the punched soft and hard glue nozzles can directly drop in the separate blanking box 7.
上模3底部的两侧分别设有导柱31,下模2顶部开设有与导柱31对应配合的定位孔26,导柱31与定位孔26的配合能使上刀6、下刀5与产品的相对位置精准定位。水口孔23及落料孔24的两侧分别形成护刀25,护刀25可防止软硬胶水口移位,提高定位准确度。Both sides of the bottom of the upper mold 3 are respectively provided with guide pillars 31, and the top of the lower mold 2 is provided with positioning holes 26 corresponding to the guide pillars 31. The cooperation of the guide pillars 31 and the positioning holes 26 can make the upper knife 6, the lower knife 5 and The relative position of the product is accurately positioned. The two sides of nozzle hole 23 and blanking hole 24 respectively form guard knife 25, and guard knife 25 can prevent soft and hard glue nozzle from shifting, improves positioning accuracy.
上刀6刃口与相对应的下刀5刃口之间的水平方向距离为0~0.02mm。若设备上刀6和下刀5的配合存在很大的间隙,冲切软胶水口时就像会切橡皮一样,有让刀现象,冲切后软胶与硬胶结合处易出现胶丝或残余水口,因此,设备上刀6、下刀5配合间隙的控制至关重要,为保证精度,上刀6、下刀5及上模3、下模2的镶刀孔均要用慢走丝来加工。且设计时要把上刀6与下刀5的配合状态设计为过盈配合,待装机调机时再用油石把上刀6、下刀5刀刃口之间的距离精磨为0~0.02mm。The horizontal distance between the edge of the upper knife 6 and the corresponding edge of the lower knife 5 is 0-0.02mm. If there is a large gap between the upper knife 6 and the lower knife 5 of the equipment, when punching the soft glue nozzle, it will be like cutting rubber, and there will be a knife phenomenon. Therefore, it is very important to control the matching gap between the upper knife 6 and the lower knife 5 of the equipment. to process. In addition, when designing, the matching state of the upper knife 6 and the lower knife 5 should be designed as an interference fit. When the machine is installed and adjusted, the distance between the cutting edges of the upper knife 6 and the lower knife 5 should be finely ground to 0-0.02mm. .
本发明的工作原理为:把带有软硬胶水口的塑胶产品放于冲切硬胶底模21上,气缸42带动升降板43和上模3向下运动,使得上刀6往下冲切,先把塑胶产品的硬胶水口冲切切掉;之后再把产品放于冲切软胶底模22上,重复上刀6冲切动作把剩余的软胶水口冲切掉,在冲切软胶水口时,同时在冲切硬胶底模21中冲切下一个塑胶产品的硬胶水口,如此循环,上模3每向下冲切一次就可加工好一模产品,生产效率高,节省人力,降低生产成本。本发明把产品的软硬胶水口分两次冲切,这样产品硬胶水口及软胶水口的相对位置就会被治具下模2定位得很准确,冲切出来的产品不会存在切伤和残留水口高的现象,冲切效果好。The working principle of the present invention is: put the plastic product with the soft and hard glue nozzle on the die-cut hard rubber bottom mold 21, and the cylinder 42 drives the lifting plate 43 and the upper mold 3 to move downward, so that the upper knife 6 is punched downward. , first die-cut the hard glue nozzle of the plastic product; then put the product on the die-cut soft glue bottom mold 22, repeat the upper knife 6 punching action to die-cut the remaining soft glue nozzle, and then die-cut the soft glue At the same time, the hard glue nozzle of the next plastic product is punched in the punching hard glue bottom mold 21, and in this way, the upper mold 3 can process a mold product every time it is punched downward, and the production efficiency is high, saving manpower ,reduce manufacturing cost. The present invention divides the soft and hard glue nozzles of the product into two die-cuts, so that the relative positions of the hard glue nozzles and the soft glue nozzles of the product will be accurately positioned by the lower die 2 of the jig, and the punched products will not have any cuts And the phenomenon of high residual nozzle, the punching effect is good.
