Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door glass guide rails, in particular to a nylon mould for trial-producing a curved vehicle door glass guide rail. Background Art

[0002] The lifting and lowering of the car door window glass needs to be achieved along the specified route, otherwise the lifting and lowering action will not be smooth, the glass will be skewed, and even the glass will be stuck and unable to be lifted and lowered. In order to enable the car window glass to move along the specified route, it is necessary to set glass guides on both sides of the glass and on the top of the window. This type of glass guide is usually a thin U-shaped steel part with a uniform cross-section, which is formed by a roller pressing process and bent at a certain curvature. Usually, when a new project is trial-produced, the car window glass guide will borrow the part section of the same platform project, but the curvature of the guide will be adjusted, and the bending part of the roller line needs to be adjusted according to the curvature of the guide. The cost of changing the roller production line to adjust the curvature of the guide is relatively high, which affects the project verification cost. Utility Model Content

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The nylon mold for trial-production of curved door glass guide rails provided by the present invention can effectively save the time for roller pressing line tooling and whole line debugging required by the traditional solution when trial-producing window glass guide rails;

[0021] 2. The present invention uses nylon material instead of steel for bending, and the low hardness and good toughness of nylon material can increase the tolerance of the mold forming size, so that thin-walled parts are not prone to quality problems such as local deformation;

[0022] 3. In the present invention, since the window frame guide rail parts are U-shaped, the rebound size after bending is uncontrollable, so it is necessary to trim the mold several times to obtain the appropriate molding size. The use of nylon material can greatly speed up the mold trimming speed, shorten the development cycle, and reduce the mold material cost;

[0023] 4. Based on the hardness and flexibility of nylon materials, the present invention can meet the middle support effect during part molding and solve the problem that the support block cannot be removed due to part deformation after molding. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model.

[0030] Example 1

[0031] As competition in the automotive industry becomes increasingly fierce, automakers are launching new models faster, and the number of models that need to be trial-produced has also increased, so various curvatures of window glass guides will also be developed. Therefore, a nylon mold for trial-produced curved door glass guides is needed, which can effectively reduce the development cost of roller line tooling and debugging in the traditional trial production process, and reduce the development cost pressure of new models.

[0032] The present invention adjusts the curvature of the existing window glass guide rail by a roller forming method into a stamping bending process; at the same time, according to the characteristics of thin-walled and U-shaped parts and the requirement to keep the structural cross-sectional dimensions unchanged after forming, nylon block materials are used to replace traditional steel materials, and a forming mold is obtained after processing, so that the forming mold can be more easily adjusted quickly according to the rebound of the parts, and it is ensured that the appearance and cross-sectional dimensions of the parts after forming meet the design requirements.

[0033] According to a nylon mold for trial-producing a curved door glass guide rail provided by the present invention, Figures 1 to 3 As shown, including:

[0034] like Figure 1 As shown, the upper template 1 and the punch 2 in the bending mold are assembled together; the window frame guide rail assembly 3 is placed in the limiting groove of the die 4 during molding, and the die 4 and the lower template 5 are assembled together.

[0035] Wherein, the male mold 2 and the female mold 4 are both made of nylon;

[0036] In bending production, such as Figure 2As shown, first insert the support strip 7 into the groove of the window frame guide rail 6, wherein the support strip 7 is made of nylon; make the inner cavity gap of the window frame guide rail groove as small as possible, then place the window frame guide rail assembly 3 in the groove on the nylon die 4, start the punching machine, and the punching machine sliding template drives the upper template 1 to move downward, so that the punch 2 contacts the window frame guide rail assembly 3, and continuously applies downward pressure to deform the window frame guide rail assembly 3 according to the designed curvature. After pressure maintenance, the punching machine sliding template drives the upper template 1 to move upward, and the bent window frame guide rail assembly 3 is obtained. The bending change process is shown in FIG. Figure 2 The support strip 7 is taken out from the window frame guide rail to obtain the bent window frame guide rail.
