As far as plastic product manufacturers are concerned

29. Precautions for parting surface: The parting surface of the rear mold must be the back mold after the two products are merged; the parting surface of the front mold must be a single product, and the merged product is not acceptable.　　 8.1mm. The depth of the front SPRUE should not exceed 65mm. 13. Generally, this kind of molding process is also called two-component injection molding, which is usually completed by a set of molds and requires a special two-color injection molding machine. The code position of the export mold should be on the operating side and the non-operating side, not on the world side, because their products must be fully automatic. The convex/concave molds at the two positions of the rotary injection mold must be consistent in size and accuracy, and fit well with the concave/convex mold.

After the front and back molds of the mold are rotated 180° from the center, they must be matched. glue. The rear mold can be matched with the front mold after rotating 180 degrees. Note: Most injection nozzles of domestic two-color injection molding machines are not adjustable.Two kinds of plastic materials are injected on the same injection molding machine, and the mold is molded twice, but the product is only ejected once. The nozzle spacing of some foreign two-color injection molding machines is adjustable, some are not adjustable, and the domestic one is not.　　22. For two-color injection molds, the gate location must be carefully selected. 0. Large molds must appropriately increase the number of ejector pin holes, and because the ejector pin attached to the injection molding machine itself is not long enough, we must design an extended ejector pin in our mold, and the ejector pin will grow about 150mm from the base of the mold base. When injection molding, the size of the first injection molding product can be slightly larger, so that it can be pressed tighter with another cavity during the second molding to achieve the effect of sealing. The basic principles of two-color injection mold design: 　　(1) hard rubber once and soft rubber twice; 　　(2) transparent once and non-transparent twice; 　　( 3) The plastic with high injection molding temperature is done once, and the molding with low temperature is done twice; 　　 2.　　21.01, the four sides and depth of the mold frame must be toleranced, otherwise, when the rear mold rotates 180 degrees, the height will be inconsistent and cause a sharp edge; the frame depth tolerance is minus 0.

A brief understanding of mold design can be made. It is better to design in accordance with the steps. Everything needs to be done in accordance with the steps, so mold design is no exception. This is how Shenzhen Plastic Mould Company designs and produces plastic moulds according to the steps. This shows that plastic products are widely used in people’s lives. Design is to better put imagination into reality. There are still many factors to consider when designing. As far as the mold is conceed, practicality must be considered, and the product designed by the plastic mold must also be usable.In people’s lives, the plastic products used are more common. As far as plastic product manufacturers are conceed, there are also many, which makes the development of this industry. If you don’t understand, please contact us!. After the design of the plastic mold is completed, the mold is produced. , Plastic products are produced by the need for molds. It can also be said that the production of plastic products. It is true that the production of plastic molds is not easy to make mistakes, so this is a more reliable way. After understanding the design of this plastic mold, I also know more about the mold. China PET mould suppliers Generally speaking, mold design also requires drawing drawings, which can produce molds. Therefore, design also needs to be completed step by step

Anyone who knows about molds knows that more people choose two-color molds than single-color molds. Because the primary material has supported the contour of the plastic product, the secondary material will not shrink more.　　 12. Please carefully check the other reference data of this type of injection molding machine, such as the maximum die thickness, minimum die thickness, and the spacing of top rod holes. When designing the cavity for the second injection, in order to prevent the cavity from inserting (or scratching) the glue position of the first molded product, a partial avoidance can be designed. If the distance between the injection point and the nozzle of the injection molding machine is different, the top rod hole should be waist-shaped, because the top rod spacing of the injection molding machine is not adjustable. It does not need to be rotated.. There are many factors.02mm. The two products of the back mold are the same, the thimble is the same, it is a rotation relationship, and must not be a translation relationship.　　27. What are the matters needing attention in the design of two-color molds?
