Description
技术领域technical field
本发明涉及一种定量浇铸溢流装置。The invention relates to a quantitative casting overflow device.
背景技术Background technique
在铸造工艺上要求金属溶液充型过程中要做到排气排渣及冒口补缩，而在浇注过程中首先进入铸型的金属溶液由于温度损失、金属氧化等因素造成气孔、渣孔、砂孔集中、失去补缩能力等铸造不良的风险极高，所以充型前端金属溶液一般通过气、冒口排出型腔。In the casting process, it is required to exhaust slag and feed the riser during the filling process of the metal solution, and the metal solution that first enters the mold during the casting process causes pores, slag holes, slag holes, etc. due to temperature loss, metal oxidation and other factors. The risk of poor casting such as sand hole concentration and loss of feeding ability is extremely high, so the metal solution at the front end of filling is generally discharged from the cavity through the gas and riser.
目前的生产主要存在三个问题：一、为达到排出金属溶液，并保证冒口补缩能力的要求，砂型上箱高度必须足够高，从而导致砂型上箱透气性差，增加铸造不良的风险，也导致了操作人员的劳动量大及生产效率低；二、冒口浇铸液从浇铸口进入型腔，液体从气、冒口排出流到地面，存在高温金属溶液在生产区域随处流淌，将影响生产环境，易造成起火、烫伤等人身安全及生产安全事故，增加设备故障风险，且对溢流液的回收利用难度大；三、操作人员无法确认金属溶液溢流量，从而无法保证浇注过程的工艺稳定性，对浇铸流量均通过经验进行判断，导致多个产品的性能有一定的差别。There are three main problems in the current production: 1. In order to discharge the metal solution and ensure the feeding capacity of the riser, the height of the upper box of the sand mold must be high enough, which leads to poor air permeability of the upper box of the sand mold and increases the risk of poor casting. This leads to a large amount of labor for operators and low production efficiency; 2. The riser casting liquid enters the cavity from the casting port, and the liquid is discharged from the gas and riser to the ground. There is a high-temperature metal solution flowing everywhere in the production area, which will affect the production. Environment, it is easy to cause personal safety and production safety accidents such as fire and burns, increase the risk of equipment failure, and it is difficult to recycle the overflow liquid; 3. The operator cannot confirm the overflow amount of the metal solution, so that the process stability of the pouring process cannot be guaranteed. The casting flow is judged by experience, resulting in certain differences in the performance of multiple products.
发明内容SUMMARY OF THE INVENTION
本发明的目的是克服上述缺陷，保证铸造件质量的同时，降低生产成本，提高生产效率，减少生产安全风险，使得浇注工艺标准化、可视化。The purpose of the present invention is to overcome the above-mentioned defects, while ensuring the quality of castings, reducing production costs, improving production efficiency, reducing production safety risks, and making the pouring process standardized and visualized.
本发明采用以下技术方案：The present invention adopts following technical scheme:
一种定量浇铸溢流装置，包括杯座；A quantitative casting overflow device, comprising a cup holder;
溢流通道，垂直方向贯穿所述杯座，设置于所述杯座的中心位置；溢流杯，位于所述杯座上，为所述溢流通道周围形成的环形凹槽，呈盆状结构；所述溢流杯的上方开口低于所述溢流通道的上开口；脱料口，设置于所述溢流杯的底部，贯通所述杯座。The overflow channel runs through the cup holder in the vertical direction and is arranged at the center of the cup holder; the overflow cup, located on the cup holder, is an annular groove formed around the overflow passage and has a basin-like structure ; The upper opening of the overflow cup is lower than the upper opening of the overflow channel; the stripping port is arranged at the bottom of the overflow cup and penetrates the cup seat.
本发明通过在铸型顶端的冒口位置增加溢流杯，一是解决了传统金属溶液冷却后收集难度大，减轻工程开箱清理的工作量，并将溢流的金属溶液收集回用，可以直接回炉重炼，减少生产浪费的同时，也使得生产安全化、洁净化；二是使得充型前端金属溶液通过溢流杯排出铸型，由于溢流通道具有一定的高度，相当于提高了冒口的高度，这就进一步提高了气、冒口的液体静压力，提升铸件的致密度，减少铸件缩松风险；由于溢流通道的高度增加了冒口的高度，所以可降低上箱高度，提高砂型透气性，减少工人造型劳动强度，提高造型效率，降低造型成本；三是可以通过观察金属溶液的溢流情况，通过工艺计算，设定金属溶液的溢流重量，从而设计适合铸造工艺的可定量的溢流杯，制定并执行浇注工序的操作标准，使得流程标准化、工艺可视化，解决传统通过经验判断导致的产品稳定性差的问题。By adding an overflow cup at the position of the riser at the top of the casting mold, the invention solves the difficulty of collecting the traditional metal solution after cooling, reduces the workload of unpacking and cleaning in the project, and collects and reuses the overflowing metal solution. Directly returning to the furnace for re-smelting reduces production waste, but also makes production safe and clean; second, the metal solution at the front end of the filling mold is discharged from the mold through the overflow cup. Since the overflow channel has a certain height, it is equivalent to increasing the risk of risk. The height of the mouth, which further increases the hydrostatic pressure of the gas and the riser, improves the density of the casting, and reduces the risk of shrinkage of the casting; because the height of the overflow channel increases the height of the riser, the height of the upper box can be reduced, Improve the permeability of the sand mold, reduce the labor intensity of workers' modeling, improve the modeling efficiency, and reduce the modeling cost; the third is to observe the overflow of the metal solution and set the overflow weight of the metal solution through process calculation, so as to design a suitable casting process. Quantitative overflow cups, formulate and implement the operation standards of the pouring process, standardize the process, visualize the process, and solve the problem of poor product stability caused by traditional judgment through experience.
