Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step are within the scope of the present invention.
Example 1: a standardized manufacturing method of injection mold parts.
A standardized manufacturing method for injection mold parts is an air-conditioning panel mold, a VG-shaped needle valve type hot runner is used, so that the requirement on the high-brightness surface of a plastic part is high, if the hot nozzle is not cooled sufficiently, injection molding defects such as scalding, sun veins and the like can be formed on the surface of a product, the product does not meet the quality requirement, the hot nozzle needs to be cooled sufficiently, and a conformal water channel is required to be arranged at the hot nozzle of the plastic part.
The structure is as shown in figure 3, a printed conformal water channel 3 (the diameter of the conformal water channel 3 is 2-20 mm) is adopted to cool a head part 2 (the size and height of the head part 2 is 10-100 mm) of the part, a water inlet section 4 is formed in a base 1 (the base 1 part adopts a standardized and serialized design, the height dimension of the base 1 part is 10-150mm, a series of integers are extracted according to a common dimension, a series of standard base 1 blanks with specifications are designed, the outer diameter of the base 1 is 30-150 mm), the part is machined in a machining mode, a water inlet hole of the water inlet section 4 is provided with a water testing screw thread 5, the bottom of the base 1 is provided with a positioning flat position 7 of a part (the size of the positioning flat position 7 is 2-50 mm), the bottom surface of the base 1 is provided with a fixing screw hole 6 (the distance between the screw hole 6 and the water inlet hole is 5-60 mm), and a clearance hole 8 (the diameter of the clearance hole 8 is 10-60 mm) is arranged in the middle of the base 1.
The manufacturing process of the part is shown in fig. 1, firstly, a base 1 blank is processed by using die steel, then a head 2 of the part is printed on the top of the base 1 blank in a 3D mode, and the printed part is put into inventory for use after being printed, as shown in fig. 2. In the subsequent die design, the splicing standard of the matching position of the hot nozzle of the model is referred to during design, a splicing part is designed, machining is carried out after the design is finished, a machining department calls a blank with a size close to the designed size from inventory to program for finish machining, and the blank comprises a positioning flat position 7, a screw hole 6, a water testing screw thread 5, a water inlet section 4 on the base 1 and the like which need to be finished. Then the final finished product is obtained and finally sent to a die assembly department for assembling the die.
Because the present embodiment uses the model of the commonly used hot mouth, so its hot mouth cooperation department is directly printed the shaping by 3D, does not need to reserve the processing allowance, can shorten processing cycle, improves machining efficiency.
In the embodiment, compared with the whole printing, the method can reduce the cost by more than 50% and shorten the printing period by 50-80%.
Example 2: a standardized manufacturing method of injection mold parts.
A standardized manufacturing method for injection mold parts, this embodiment is a dehumidifier back shell mold, use PG type open hot runner, the part structure and manufacturing procedure in this embodiment are basically the same as embodiment 1, the difference is that the hot mouth of this model is not commonly used, because the difference of different model hot mouths is basically the head and mould cooperation place, so merge the blank that this model hot mouth adopts with the blank of other not commonly used hot mouth, design a blank with stronger commonality, this blank and embodiment 1 different position leave the processing allowance for hot mouth cooperation place 9 (as shown in figure 4), after confirming the hot model mouth that this set of mould uses in the later stage, reprogram and mill the cooperation place to the corresponding shape.
In the embodiment, because the hot nozzle with the model is not commonly used, a part blank with higher universality is designed, and the part blank and other hot nozzles with different models are commonly used for the same model, so that the production cost can be effectively reduced. In addition, the design of the base and the head blank of the part is reserved with machining allowance with reasonable size, and the structural strength, the water path safety distance and the like of the finished part can be guaranteed.
