Dalam proses rawatan haba, ubah bentuk acuan suntikan ketepatan sering berlaku. Untuk mengelakkan fenomena buruk seperti ini, selagi kita memahami undang-undang ubah bentuk dan menganalisis penyebabnya, kaedah yang berbeza boleh digunakan untuk mengelakkan ubah bentuk acuan, yang boleh dikurangkan dan dikawal. Secara umum, kaedah berikut boleh diguna pakai untuk mengelakkan ubah bentuk acuan suntikan ketepatan semasa rawatan haba.
(1) Pemilihan bahan yang munasabah: untuk acuan suntikan ketepatan, micro deformation mold steel with good material shall be selected; for mold steel with severe carbide segregation, fair casting shall be carried out; for large and non casting mold steel, solution double refining heat treatment can be carried out.
(2) The mold structure design should be fair, the thickness should not be too different, and the shape should be symmetrical. For large-scale and precision injection mold, the deformation law should be grasped and machining allowance should be reserved. For large-scale and precision injection mold, the combined structure can be used.
(3) The precision injection mold should be pre heat treated to eliminate the residual stress in the machining process.
(4) Reasonable selection of heating temperature and control of heating speed. For precision injection mold, slow heating, preheating and other balanced heating methods can be adopted to reduce the deformation of mold heat treatment.
(5) Under the condition of ensuring the hardness of the mold, the pre cooling and graded cooling quenching or temperature quenching process of the injection mold should be adopted as far as possible.
(6) For precision injection molds, under the premise of permission, vacuum heating quenching and deep cooling after quenching shall be used as far as possible.
(7) For some precise and complex dies, pre heat treatment, aging heat treatment, tempering and nitriding heat treatment can be used to control the accuracy of the dies.
(8) When repairing mold sand hole, air hole, wear and other defects, select repair equipment with small thermal impact such as cold welding machine to avoid deformation in the repair process.
There are many methods for heat treatment process operation, including hole plugging, hole binding, mechanical fixation, appropriate heating method, accurate selection of cooling direction and moving direction in the cooling medium, dan lain-lain. reasonable tempering heat treatment process is also an effective measure to reduce the deformation of precision injection mold.
The raw materials of plastic products in the domestic market are mainly as follows (sebagai contoh, some raw materials):.
PP: low transparency, low gloss, low rigidity, but it has stronger impact strength. It is commonly used in plastic buckets, plastic basins, folders, drinking pipes, dan lain-lain.
PC: ketelusan yang tinggi, high gloss, very brittle, common in water bottles, space cups, milk bottles and other plastic bottles.
Abs: resin is one of the five major synthetic resins. It has excellent impact resistance, Leburan mengalir ke dalam rongga penyejukan dan kehilangan haba akibat pengaliran haba, Leburan mengalir ke dalam rongga penyejukan dan kehilangan haba akibat pengaliran haba, rintangan kimia, injection processing and electrical performance. It also has the characteristics of easy processing, stable product size, good surface gloss, dan lain-lain. it is mainly used in milk bottles, space cups, kereta, dan lain-lain.
HIDUP: the main products are mineral water bottle cap, PE fresh mold, milk bottle, dan lain-lain.
PVC: mainly used for plastic bags, packing bags, drainage pipes, dan lain-lain.
PS: printer shell, electrical shell, dan lain-lain.
All plastic products have a variety of colors, and this color is mixed with pigments, which is also the technical core of plastic products. If the color ratio is good, the sales volume is very good, and the boss also attaches great importance to the privacy of color ratio.
Secara umum, the raw materials of plastic products are mixed, such as ABS with good glossiness, PP with good resistance to falling, PC with high transparency. New products will appear by using the characteristic mixing proportion of each raw material, but such products are generally not used for food appliances.
Pada masa kini, plastic products are made by injection molding or blow molding, so every time a sample is designed, a new mold must be opened, and the mold generally varies from tens of thousands to hundreds of thousands, so in addition to the price of raw materials, the cost of mold is also very large. To make a finished product, there may be many parts, and each part needs an independent mold.
