Mold production process

Including multiple grinding of the working surface and wear parts replacement after the life of a 1, 1 mold production process includes five stages: namely, the production

Life. Production technology preparation; preparation of materials; mold parts and components of

13 different types of mold normal damage form is not a processing; assembly debugging and trial identification.

Sample, but in general the form of damage to the surface of the work of friction 2 production technology to prepare for the stage of the work includes the design of the mold drawings

damage, plastic deformation, cracking, fatigue damage, nibbling. Design; the preparation of technical documents; material quotas and processing

14 mold parts surface of the classification of many ways, can be divided into the development of working hours quota; mold cost valuation.

Forming surfaces, molding surfaces and structural surfaces. 3 process: in the mold production process, directly change

15 forming surface: refers to the mold directly determine the shape, size, accuracy, performance and assembly relationship

piece shape, size, accuracy of the surface and the production process with these surfaces.

The relevant surface of the adjustment. 4 mold process documents mainly include mold parts processing work

16 plane shape surface processing can be in the bullhead planer, standing art regulations, mold assembly process points and process regulations, the original

milling machine, gantry planer for planing and milling, go to the list of materials, purchased parts list and list of outsourced parts. Mold

In addition to most of the machining allowance on the blank. From the production efficiency craftsmen should be in a full understanding of the mold structure, the original work

consideration, the large plane more gantry planer bed planing processing; rationale and requirements of the case.

Medium-sized planes are mostly used bullhead planer planing processing; medium and small 5 mold process work the main content: 1 preparation of process documents

Type planes are mostly used vertical milling machine milling processing. Pieces of 2 two types of tool design and process preparation 3 processing processing now

17 molding surface processing is divided into two major steps, the first step is the field of technical issues 4 to participate in the trial mold and identification work.

Dimensional machining, universal a variety of different methods to achieve the design of Figure 6 characteristics of the mold process:1 mold as much as possible on the use of universal

like the required dimensional accuracy and positional accuracy. The second step is through the universal machine tool, universal tool gauges and instruments, as far as possible to reduce

The grinding and polishing of the finishing process, so that the molding surface to achieve the number of less special two types of tools.2 in the mold design and manufacturing

Design patterns required by the surface roughness and shape accuracy. Manufacturing more on the use of "real matching method", "the same boring method".3

18 blanks are mainly considered in the following areas:1 mold materials in the manufacturing process arrangements, the process is relatively centralized to ensure that

The category of the 2 mold parts Category and role3 mold parts mold processing quality and progress, simplify the management and reduce the process

Geometric features and dimensional relationships. Turnaround time.

19 The blank form of mold parts is mainly divided into:prototype material, 7 mold technical and economic indicators:precision and rigidity of the mold,

Forging parts, casting parts and semi-finished parts of four kinds. The production cycle of the mold, the production cost of the mold and the mold

20 prototype material of the main undercutting method: shearing method, sawing method, life four basic aspects.

Thin sheet wheel cutting method, flame cutting method. 8 The main factors affecting the accuracy of the mold are: 1 product parts

21 forging quality requirements have four aspects: the quality of raw materials and precision 2 mold processing technology means of the level of 3 mold load

measurement of the state and the preparation of materials; forging hammer tonnage selection whether or not to match the level of technology of the clampers 4 mold manufacturing production methods and

reasoning; forging blanks of the heating, cooling Temperature, each forging management level.

The amount of deformation and other process parameters are correct; forging mode of selection 9 mold production cycle is from the acceptance of the mold order task open

Selection and the size of the forging ratio. Beginning to the mold test mold identification after the delivery of qualified molds used

22 mechanical profiling according to the mold plate by the installation of the different positions of the time.

For leaning against the plate to imitate the shape, the tool holder to imitate the shape and the tailstock to imitate the shape of the mold by 10 major factors affecting the mold production cycle are:1 mold

Die imitation. Technology and production of standardized degree 2 mold enterprise specialization

23 embossing processing convex mold: first concave mold, first pre-processing convex mold degree 3 mold production technology means of modernization 4 mold

blanks on all sides, in accordance with the vertical milling machine, according to the scribing line roughing out the production of the operation and management level.

The forming surface of the convex die, the convex die in the case of fully lubricated 11 mold production costs of the main factors are:1 mold structure of

Under the pressure into the concave die that has been hardened the type of aperture mouth, excess gold complexity and mold function of the high and low 2 mold accuracy of the high

Genus was concave model aperture extrusion, and then extruded the excess metal of the low 3 mold material selection 4 molds Processing equipment 5 mold

File away. The degree of standardization and the degree of specialization of enterprise production.

24 hole system: concave mold, convex mold fixed plate, upper and lower mold seat, etc. often 12 mold life: refers to the mold to ensure the quality of the product parts

with a series of round holes, the size of each hole and the premise that they can be processed under the total number of parts, which includes
