下面结合附图对本发明作进一步说明。The present invention will be further described below in conjunction with the accompanying drawings.
如图1-4所示,一种具有异形承重件的桌子,包括左右两个桌脚8,每个桌脚8的内侧配合安装一异形承重件3,两个异形承重件3之间共同配合安装桌板支撑部9,桌板支撑部9上配合安装桌板10,所述异形承重件3包括钢制件1和包覆于钢制件1外的PU包覆件6。As shown in Figures 1-4, a table with a special-shaped load-bearing member includes two left and right table legs 8, and a special-shaped load-bearing member 3 is installed on the inner side of each table leg 8, and the two special-shaped load-bearing members 3 cooperate together. The table support part 9 is installed, and the table board 10 is installed on the table support part 9 .
钢制件1上开设一组方便注塑的导流穿孔100以及一组方便与其它部件连接的螺丝孔101和穿线孔102,PU包覆件6上开设与螺丝孔101对应的第一通孔600、与穿线孔对应的第二通孔601。A set of diversion holes 100 for easy injection molding and a set of screw holes 101 and threading holes 102 for connecting with other components are provided on the steel part 1, and a first through hole 600 corresponding to the screw holes 101 is provided on the PU covering part 6 and a second through hole 601 corresponding to the threading hole.
如图5-8所示,一种上述异形承重件的制作方法,包括As shown in Figures 5-8, a method for manufacturing the above-mentioned special-shaped load-bearing member, comprising:
步骤S1:设计制作钢制件1;Step S1: Design and manufacture steel part 1;
步骤S2:将钢制件1定位于模具2内;Step S2: positioning the steel part 1 in the mold 2;
步骤S3:对模具2进行浇注,使浇注物包围钢制件,浇注物为PU,浇注后合模待干;Step S3: pour the mold 2, so that the pouring material surrounds the steel parts, the pouring material is PU, and the mold is closed after pouring and waits for drying;
步骤S4:脱模,得到异形承重件3。Step S4 : demoulding to obtain a special-shaped load-bearing member 3 .
对步骤S1的进一步说明:先要对异形承重件3的内埋钢制件1结构进行设计,钢制件1的钢板厚度与结构要满足该异形件的承重需求,也就是钢制件1实际上是整体骨架,外部PU包覆件6只是满足异形外观需求,钢制件1钢板宽度超过300毫米时要在钢板中间开设导流穿孔100,便于浇注时浇注物在模具2的模腔内导流。若异形承重件3在使用时需要与其它部件连接配合,则在钢制件1上开设用于连接的螺丝孔101和穿线孔102。Further explanation of step S1: First, the structure of the embedded steel part 1 of the special-shaped load-bearing part 3 should be designed, and the thickness and structure of the steel plate of the steel part 1 should meet the load-bearing requirements of the special-shaped part, that is, the actual steel part 1. The upper part is the overall skeleton, and the external PU covering part 6 is only to meet the requirements of special-shaped appearance. When the width of the steel plate of the steel part 1 exceeds 300 mm, a diversion hole 100 should be opened in the middle of the steel plate, so that the casting material can be guided in the cavity of the mold 2 during pouring. flow. If the special-shaped load-bearing member 3 needs to be connected and matched with other components during use, the steel member 1 is provided with screw holes 101 and thread holes 102 for connection.
对步骤S2的进一步说明:异形承重件3是通过模具2以浇注模方式生产加工,在模具2制作时模腔内壁上要预留用以支撑定位钢制件1并使之悬空的凸台7,凸台7具体为螺母,凸台7的位置与数量视钢制件1的大小与形状而定,钢制件1与模具2模腔内壁最小间距≥5毫米,小于此厚度钢制件1表面的PU包覆件6太薄会影响其对钢制件1表面的附着力,容易造成表面PU包覆件6脱落,在将钢制件1放入模腔前需在模腔表面喷涂脱模剂,以便脱模。模具2浇注前先将钢制件1固定在模腔的凸台7上,钢制件1上所有的螺丝孔101采用螺杆4堵住,上述的螺母与螺丝孔101一一对应,螺杆4同时拧入螺丝孔和螺母内,所有的穿线孔102采用堵栓5堵住,此举是为了防止糊状混合物流进孔后堵塞影响后续使用,螺杆4与堵栓5外留长短以到模腔内壁为准,预留到模腔内壁是为了承重件脱模后,PU包覆件6上形成与螺丝孔101与穿线孔102对应的孔位。Further explanation of step S2: the special-shaped load-bearing member 3 is produced and processed by the mold 2 in a casting mold mode. When the mold 2 is made, the inner wall of the mold cavity should be reserved to support the positioning of the steel part 1 and make it suspended. The boss 7 , the boss 7 is specifically a nut. The position and number of the boss 7 depends on the size and shape of the steel part 1. The minimum distance between the steel part 1 and the inner wall of the mold 2 cavity is ≥5 mm, which is less than the thickness of the steel part 1. If the PU coating 6 on the surface is too thin, it will affect its adhesion to the surface of the steel part 1, and it is easy to cause the surface PU coating 6 to fall off. moulding agent for release. Before pouring the mold 2, fix the steel part 1 on the boss 7 of the mold cavity. All the screw holes 101 on the steel part 1 are blocked by the screw 4. The above-mentioned nuts correspond to the screw holes 101 one by one, and the screw 4 simultaneously Screw into the screw holes and nuts, and all the threading holes 102 are blocked with plugs 5. This is to prevent the paste mixture from flowing into the holes and blocking the subsequent use. The inner wall shall prevail, and the inner wall of the mold cavity is reserved for the purpose of forming holes corresponding to the screw holes 101 and the threading holes 102 on the PU covering member 6 after the load-bearing member is demolded.
对步骤S3的进一步说明:步骤S3中具体浇注的是MDI与多异氰酸酯混合物,两者形成PU材料,MDI为多苯基多亚甲基多异氰酸酯,简称PAPI,浇注量按 450-550kg/m 3计算,比例太大PU包覆件6固化后密度大表面光滑后续做油漆时油漆附着力差,比例太小固化后密度相对较小表面做完油漆后易碰伤,混合物注完后合模待干,待干时间≥1.5小时。 Further explanation of step S3: Step S3 is particularly cast MDI mixture and a polyisocyanate, the two form a PU material, MDI is a polyphenyl polymethylene polyisocyanates, referred to as PAPI, pouring amount by 450-550kg / m 3 Calculation, if the proportion is too large, the PU coating part 6 has a high density after curing, and the surface is smooth, and the paint adhesion is poor during subsequent painting. If the proportion is too small, the density is relatively small after curing. Dry, the time to dry is ≥ 1.5 hours.
对步骤S3的进一步说明:脱模后顺便拆出螺杆4与堵栓5。Further explanation of step S3: after demoulding, remove the screw 4 and the plug 5 by the way.
