Construction of daily necessities mold
The mold adopts the I-shaped die structure, the cavity and core are selected P20 or 718, the slider, guide chute and insert are heat treated by 2316 or H13, and the guide post, guide bush, sprue bushing, pulling rod and reset lever adopt SKD61 standard. The mold base is made of self-made standard formwork. Corrosion resistance, toughness, thermal conductivity and hardness of good materials make polishing easier, saving production cycle and cost, extending mold life, reducing maintenance and repair time, reducing the risk of cracking and improving Production efficiency.
Mold cooling system design
The design of the cooling system is a relatively complicated work, that is, the cooling effect and the uniformity of the cooling should be considered, and the influence of the cooling system on the overall structure of the mold should be considered. The specific position and size of the cooling system are determined; Or cooling of the inserts; cooling of the side slides and side cores; design of the cooling elements and selection of cooling standard components. The company began to analyze these series of problems in the mold design. The mold uses circulating water to flow in every part of the mold, reducing the cooling time during injection molding, improving the production efficiency of the product and greatly reducing the production cost.
Mold design and processing
General daily necessities and other assembly aspects: the main body and the bottom cover assembly is good in the form of double buckles, that is, the product bottom double card, the upper shell is directly inserted, so that it is not easy to be misplaced, the product assembly gap is even, the process seam is good. 0.5MM, the general plastic product zui is afraid of shrinking the yin, the screw column and the rib position under the product is prone to shrinking, and the good method is to reduce the wall thickness around the screw column by 0.8-1 MM, which is actually white. For whitening, general lighting and demoulding slope, PP material product release angle should be at least 0.5 degrees, ABS material product drafting slope should be at least 1.5 degrees, ejector good design in products The surrounding area is also the place where the force is better. When the mold is processed: it will send you the whole process of the mold flow. After the mold material is purchased, the picture will be sent to you. After the processing is completed, the picture will be sent to you, then the mold. Report to you again when you assemble, and then I will send you samples, I will let you see our process in the whole process.
