Plastic mold design must be grasped when it must be grasped

  1. The focus during design (1) The inlet of the inlet should be opened in the thick part of the product to ensure the smooth and complete charging model; (2) Try to open as much as possible at the edge or bottom; (3) The cold material cave near the pouring mouth is often set up to facilitate the lane -of -the -way release; (4) Large or flat products, it is recommended to use multi -point pouring, which can prevent the product’s warning and lack of materials; (5) The position of its position should be selected to the shortest point of the plastic charging process to reduce the pressure loss, which is conducive to mold exhaust; (6) Avoid opening the mouth near the slender core, so as not to directly impact the core core, generate deformation or bending; (7) The size of the mouth is determined by the size of the product, the geometric shape, the structure and the type of plastic. (8) You can determine the product’s combination line that produces due to the location of the mouth through

The design idea and process of a set of practical injection molds

A reliable plastic mold design is mainly reflected in the quality (appearance quality and size stability) of the forming plastic products. It is convenient, fast, and concise when processing and manufacturing. Safe, stability, easy maintenance, short molding cycle, long life life, and reasonable mold manufacturing process in injection molding. 01. The main process of factory mold design Customers provide product map → analyze product → confirm plastic varieties → confirm mold material → transfer engineering chart → multiplier as a mirror phase → improve the formation map → make models → make models → unplugged → 3D division → determine the runner road /Putting the mouth method → refer to the rank diagram for structural design → disassembling mosaic → correction 3D → engineering drawing (mold/inlaid parts/mold/loose parts) → do BOM table → school pairing review. 02. Several aspects that should be paid attention to 1) When we start the mold design, we should pay more attention to severa

Maintenance and maintenance methods of injection molds

 1. Always keep the injection mold thimble and guide post lubricated (the most suitable lubricant should be selected), and regularly check whether the thimble, guide post, etc. are deformed and surface damaged. Once found, replace it in time. 2. Pay attention to the surface maintenance of injection molds. It directly affects the surface quality of the product. The focus is on preventing rust. Therefore, it is particularly important to choose a suitable, high-quality, and professional anti-rust oil. 3. Each injection mold should be equipped with a resume card to record and count its use, care (lubrication, cleaning, rust prevention) and damage in detail. Based on this, you can find out which parts and components have been damaged and the degree of wear to provide discovery And information materials to solve the problem. 4. After each production cycle, the band heaters, rod heaters, heating probes and thermocouples on the injection mold should be measured with an ohmmeter. If they are da

There are 6 categories of plastic molds, do you know all of them

  Plastic molds are tools that are matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise dimensions. According to the different molding methods, it can be divided into different types of molds. 1. Injection Mold It is mainly a molding mold that is most commonly used in the production of thermoplastic parts. The corresponding processing equipment of the injection mold is an injection molding machine. The plastic is first heated and melted in the heating cylinder at the bottom of the injection molding machine, and then melted in the screw or column of the injection molding machine. Driven by the plug, it enters the mold cavity through the nozzle of the injection molding machine and the pouring system of the mold, the plastic is cooled and hardened to form, and the product is demolded. 2. Blow Mold A mold used to form plastic container hollow products (such as beverage bottles, daily chemical products, etc.)
