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 damaged, they should be replaced in time and matched with the mold resume. Make comparisons and make records so that problems can be discovered in time and countermeasures can be taken.

In addition, we should also ban hard objects such as iron wires and steel bars to clean injection molds to avoid scratching the surface. If there are rust spots caused by corrosive injection molding, use a grinder to polish and spray professional anti-rust oil.

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

China’s mold capital-Huangyan industrial cluster becomes a provincial pilot

Huangyan mold  industry is mainly based on the manufacture of  injection molds , including extrusion, blow molding, die-casting, and stamping molds. It has formed an industrial ecological chain system with the most complete functions, the highest degree of specialization, and the most complete supporting system at the county level in the country. . In 2009, Huangyan Mould Industry was in c luded in the “Zhejiang First Batch of 21 Demonstration Zones for the Transformation and Upgrading of Mass Economy to Modern Industrial Clusters”, and has more than 10 national and provincial honorary titles including the “First Demonstration Zone for Quality Improvement of Mold Products in the Country”. , In 2016, Huangyan District “Demonstration Zone for Intelligent Manufacturing of Moulds” was selected as the first batch of pilot demonstration zones for intelligent manufacturing in Zhejiang Province. The overall goal of the new intelligent manufacturing pilot of the Huangyan smart mold industry clu
