Embodiment 1

[0055] refer to Figure 1-Figure 8 , is a kind of mold preparation method disclosed by the present invention, comprises the following steps:

[0056] S1: Preparation process design, process design and mold design according to the shape and structure of the product, divide the mold into two parts: the mold main body and the non-main body mold, the mold main body is divided into the direct molding product surface and the structural mold part, and the non-main mold part is For the mold part of the auxiliary molding product, the non-main mold is designed in the same plane as the parting surface 6 of the mold body 1; the stereolithography molding part is selected, and the surface roughness of the product requires Ra (contour arithmetic mean deviation) ≤ 50 μm for the mold body 1 The part is molded by stereolithography mold as part 1 of the main body of the mold, and other parts (such as gate, riser 2, etc.) are molded by wood mold, which are non-main mold parts.

[0057] The desig...

Embodiment 2

[0071] refer to Figure 9 , is a rail vehicle connector disclosed in the present invention, including a mechanical coupler 20 and an electrical coupler 21, both of which are prepared by the mold in Example 1, and then quickly assembled, which is not only convenient for production, And the work efficiency is higher.

Abstract

The invention relates to a mold preparation method, a mold and a railway vehicle connecting piece. The mold preparation method comprises the following steps that S1, a preparation process is designed; s2, designing and manufacturing a mold, machining a mold main body according to the shape designed in the S1, and preparing a non-main-body mold part. S2.1, mold main body processing: processing the mold main body by adopting a three-dimensional photocuring forming method, and processing a parting surface of the mold main body into an open type; (S2.2) mold main body hardening: the processed mold main body is put into an ultraviolet oven for hardening; (S2.3) the mold main body is roughly ground; s2.4, the mold body is finely ground; s2.5, the non-main body mold and the mold plate are machined; s3, mold assembling is conducted, specifically, the mold is assembled; s3.1, the non-main body mold and the mold main body are installed; and S3.2, the template and the mold body are sealed. The mold preparation efficiency is improved, the development period is shortened, the use amount of the photosensitive resin is reduced, and the mold preparation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of general vehicles, in particular to a method for preparing a mold, the mold and rail vehicle connectors. Background technique [0002] Mold is an important equipment in modern industrial production, and its manufacturing level directly determines product quality, efficiency and new product research and development capabilities. There are many methods of traditional mold manufacturing, such as CNC milling, forming grinding, EDM and so on. However, these methods have problems such as long cycle time and high cost when manufacturing molds with complex structures. With the intensification of international competition and the development of market globalization, product upgrading is accelerating, and multi-variety and small batches have become an important production method in the mold industry. This production method requires shortening the mold manufacturing cycle and reducing the mold manufacturing cost. ...
