The plastic material of knife and fork spoon generally has PP PS two kinds. Different plastic materials, the choice of steel material of the mold is also different. The steel material of the knife, fork and spoon mold generally chooses H13, S136,2344,2316, quenching material and other steel materials. Because the knife, fork and spoon products belong to fast consumer goods, so the mold is generally opened into multi-cavity, and the mold is designed into a square or round. If the mold is designed to be square, then the semi-heat flow, the mold made of insert. The processing technology of Leo knife, fork and spoon mold has high-speed fine carving, high speed milling and so on. Ordinary knife, fork and spoon mold is generally two flap mold, and the folding of the knife, fork and spoon mold, on the basis of the two flap mold more slide. So folding knife and spoon mold is more difficult than ordinary knife and spoon mold.
Leiao company should generally follow the following basic principles when choosing the plastic chair mold classification surface:
① Classification surface should be selected at the outline of the plastic parts
② Determine the favorable mold retention mode to facilitate the smooth release of plastic parts
③ Ensure the accuracy of the plastic parts
④ Meet the appearance and quality requirements of the plastic parts
⑤ Easy for mold manufacturing and processing
⑥ Note the effect of the focus on the subtype area
⑦ Impact on exhaust effect and side core extraction
In the actual design, it is impossible to meet the above principles. Generally, we should grasp some important requirements in the technical requirements of the chair, and determine the reasonable classification surface under this premise. So, the structure of a pair of plastic chair mold is unreasonable to see its classification surface.
Mold characteristics: plastic cup mold cooling: using circulating water, effectively improve product quality and mold efficiency.
Medium-stage treatment of plastic cup mold: adjust quality and improve hardness.
Post treatment of plastic cup mold post treatment: post treatment: nitride treatment, plastic mold surface hardness is greater than HV 850, quenching treatment, the overall hardness of mold cavity can reach HRC 48 degrees above.
Plastic cup mold is a common daily necessities mold, there are a lot of mold, plastic cup mold, toothbrush cup mold, milk cup mold, mug mold, aviation cup mold, thermos cup mold and so on.model
With high-speed lathe processing, high precision, long life, cologne do plastic cup mold is more and more popular with the market, has rich experience in making plastic cup mold, through our company mold production process, not only can improve the life of the mold, but also can increase the plastic cup mold injection gloss of the surface of the product, at the same time will not appear fly / wool.
The hanger mold is an important factor in the hanger shape and quality. The hanger mold in the mold classification is almost all classified as the classification of injection mold, mainly related to the processing and use of the mold. Specifically, the heat melting material is injected from high pressure into the coat hanger mold cavity, after cooling and curing, to get the coat hanger forming product. The coat hanger injection molding process can be roughly divided into the following six stages: “mold-injection-pressure preservation-cooling-open mold-plastic coat hanger removal”, the above process is repeated, can be continuous production of products. The hanger mold can be made into multi-chamber mold, a mold can be out of multiple hanger products. Now in the process of mold processing, the production of one two and one four hanger mold majority.
Over the years, Leiao has made hundreds of pairs of litter box models. The steel material of the cat litter box mold generally uses P20 or 718 steel material. Making cat litter box mold cooling system design is a more numerous lock work, namely to consider the cooling effect and cooling uniformity, and consider the influence of the overall structure of the mold the specific position and size of the cooling system in mold design began to analyze these a series of problems, mold in the way of circulating water inside the mold flow, reduce the cooling time of injection molding, improve the production efficiency of products, greatly reduce the production cost.
There are so many kinds of trash cans, For example, trash cans used in sanitation and sanitation systems, large in size, The 240L trash can has reinforced turning edge and bucket cover fixing holes, Garbage can plastic piece is a end cover part, With relatively thin walls, Easy to pull the deformation, Easy top deformation, Generally using plastic mold integrated injection molding molding, But trash can parts are often because after forming, cooling shrinkage, Ctightly around the core, In the process of moulmolding, Due to the large force area of the lateral walls, Make the huge friction between the product and the surface of the core exist, When the top rod is pushed out of the product, It is difficult to emerge, Thimble bending, Thimble tops the product out of the white dot defect settings to top the product through.
Plastic flowerpot is a kind of flowerpot made of plastic, which is more commonly used in people’s life. Compared with the traditional porcelain flower pot, watering less times, the price is relatively cheap, accidentally destroyed, durable. With the progress of society, people’s living standards continue to improve, the need to be more ideal than the traditional flower pot, a multi-purpose plastic flower pot, such as rectangular flower pot, wall hanging flower pot, hanging basin, function and water storage flower pot, automatic watering flower pot, water detection and so on. Plastic pot is low price, high practicality; light texture, easy to carry; not easy to break the essence, more durable; and easy to clean.
A pair of high quality beach chair mold has an important relationship with its mold structure form, and the classification surface is an important factor to determine the mold structure form, and is also closely related to the overall structure of the mold and the mold manufacturing art. The classification surface directly affects the flow characteristics of plastic melt and plastic demolding. Design of classification surface: because the typing surface is affected by the molding position in the mold, the design of pouring system, plastic structure process and precision, shape and destruction method, mold manufacturing, exhaust, operation process and other factors, so the selection should be comprehensively analyzed in the selection of classification surface.
Plastic basket mold is very common household mold, very widely used, mold using high-speed lathe processing, high precision, long life, make the basket can be used in agriculture, business, household, plastic basket is very common in daily life, such as washing vegetables basket, dirty basket, shopping basket and so on have plastic material, belong to the plastic basket. It can be seen that the wide application of plastic basket.
