Abstract

The present invention provides a forming mould and forming method for manufacturing a bathroom hanger fitting, mainly including a special mould configuration comprised of a base, a fixed mould member, a movable mould member, a driving device and a pressing die whereby a blank that is heated to a proper temperature is placed in a cavity between the fixed mould member and the movable mould member. The portion of the mould cavity that forms a bottom end of the hanger fitting is facing upward whereby an opening is formed at an upper side of the mould cavity and confronting the pressing die. By means of the movable mould member brought into engagement with the fixed mould member and the pressing die forcibly moved downward to have a forming end of the pressing die inserted into the cavity via the opening, an unfinished fitting having a mounting slot defined therein is formed. Thus, costs and materials can be substantially reduced.

Description

476683

The present invention provides a forming mold for a bathroom rack joint and a forming method thereof, which mainly uses a movable die seat of the forming die to abut against a fixed die seat, and causes the stamping part to be punched down to be fixed in the die cavity to promote the die. The embryo material in the cavity can directly form a rough embryo of the hanger joint with a set of grooves, thereby achieving the practical purpose of greatly reducing the processing and material costs. According to the press, the bathroom rack connector is a connection structure for fixing the towel rack bar or the tray to the wall. Generally, the hanger connector (B) conforms to the optimal assembly angle of the towel rack bar and the tray. The structure is generally composed of a seat end (10) and a head end (11) whose axial directions are perpendicular to each other (as shown in FIG. 1). 'The seat end (1 0) must form an assembly groove (1 7) In order to lock the assembly on the assembly seat, the head end is provided with a seat hole (12) for the towel rack rod or storage tray to be assembled and positioned. The general manufacturing method of the hanger joint (B), here, especially Refers to the integrally formed hanger joint structure. The manufacturing method and steps are as follows. • It is made by punching and forging using the upper and lower die seats with corresponding mold cavities (as shown in Figure 2). In order to consider the convenience of demoulding the upper and lower mold bases, the angle of the bending type hanger joint (B) in the mold is controlled to the state as shown in the figure, and therefore, it promotes the The rough embryo (A) after demolding is a solid structure (as shown in Figure 2), and then the rough embryo (A) can be used The processing machine drills and cuts to form the seat hole (1 2) part of the head end (11) of the hanger joint (B) and the assembly groove (丨 7) part inside the seat end (10), and then passes through the detail The processing side forms the final product, and the disadvantages of this method of manufacturing and molding are as follows: 1. High processing costs: expensive two-axis processing machines must be used to cut and form the seat of the head end (11) at the same time. Assembly slot of hole (12) and seat end (10)
