The role of mould manufacturing workpieces is closely related to assembly. In order to make mould assembly completed successfully, we need to understand the preparations for mould assembly, so that the role of moulded parts will be better and better. The main six main points of its mould assembly preparation work:

1. Familiar with assembly process regulations

The assembly process specification of the injection mould is the process document of the mould assembly process and operation method, and also the technical document that guides the mould assembly work, and is the basis for the assembly production plan and technical preparation. Therefore, before assembly, workers must carefully read the assembly process regulations, understand and master the entire process of the assembly mould.

2.Thoroughly understand the assembly drawing

Assembly drawing is the main basis for mould assembly. In general, the structure of the mould largely determines the assembly sequence and method of the mould. In-depth analysis of assembly drawings, assembly drawings and parts drawings can provide an in-depth understanding of the structural characteristics and working performance of the mould; understand the role of each part in the mould and their interrelationships, coordination requirements, and connection methods to determine reasonable assembly Benchmark, combined with process specifications to formulate assembly methods and assembly sequence.

3. Checking and checking parts

According to the parts list on the assembly drawing, check whether the number of parts is enough, then carefully clean each part, and then carefully check the main parts, such as the shape and dimensional tolerances of the cavity, find out the clearance of the matching surface of each part, and the processing allowance The amount, whether there are deformation and crack defects.

4. Master the technical conditions for mould acceptance.

The technical conditions for mould acceptance are the mould quality standards and acceptance basis, as well as the process basis during assembly. This acceptance technical condition is mainly the technical requirements of the technical agreement signed with the customer and the product drawings and reference to the quality standards promulgated by the country, so before assembly, workers must fully understand these technical conditions so that they can pay full attention to during assembly. To assemble a qualified mould.

5.Open up assembly sites

When assembling the mould, there needs to be a good assembly site. The site must be clean and tidy without any debris. At the same time, the necessary tools, clamps, measuring tools and other required assembly equipment used for assembly must be prepared and wiped. Clean and open up a civilized production site.

6. Prepare standard parts and related materials

Each set of moulds has many standard parts, such as screws, pins, nuts, springs, etc. Although they are not many in number, but there are many specifications, in order to smooth the assembly, these standard parts must be found one by one at the beginning of assembly. In order to make it easy to find when assembling, in addition, auxiliary materials such as rubber, adhesives, etc. required for assembly must also be prepared as needed.
