Abstract

A locally electroplating mold, comprising a strip type double-thread screw, and an upper blocking plate and a lower blocking plate which are tightly screwed on two ends of the screw and are used for tightly clamping a plurality of electroplate workpieces, wherein a hanging plate is connected on the upper of the upper blocking plate. Because the plurality of electroplating workpieces sleeved out of the screw are tightly clamped by blocking plates screwed at two ends of the double-thread screw, side faces and internal faces of the workpieces are completely isolated to an electroplating solution, thus only external surfaces of the workpieces are electroplated, thereby raising local electroplating efficiency; the side faces and the internal surfaces does not need to be machined after electroplating, thereby saving electroplating material and saving production cost. The electroplating mold has a reasonable structure. In addition, the electroplating mold is convenient for assembling and disassembling, can be repeatedly used, a batch of electroplating member can be replaced for another after electroplated.

Description

The parcel plating mold

[technical field]

The present invention relates to the special-purpose parcel plating mold of a kind of usefulness comes holding workpiece to carry out the instrument that local outside surface is electroplated.

[background technology]

We know; one deck zinc or chromium etc. on the outside surface of many metal partss, have all been electroplated; to reach the effects such as attractive in appearance or erosion resistance of reinforcing member; owing to be not that whole parts surface is electroplated, just show most important so how to carry out the protection at the electroless plating position (side, internal surface etc.) to metal parts.Current people way relatively more commonly used is earlier whole parts to be placed in the electroplate liquid its surface is electroplated comprehensively; do not carry out processing such as grinding to wanting coated surface again after having electroplated; or coating protection is carried out on the surface that will not need in advance to electroplate; or adopt the method for rubberized fabric to carry out the electroless plating surface protection; these methods not only can cause the waste of plated material; and can increase man-hour, and increasing production cost greatly, electroplating effect is also undesirable.

[summary of the invention]

The objective of the invention is to be to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, production efficiency is high, can carry out in batches the parcel plating mold of the laggard electroplating outside surface of clamping to part, disposable like this outside surface is electroplated, thereby neither can waste plated material, can save production cost again, it is also reusable.

In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposals:

A kind of parcel plating mold, it comprise long strip type double threaded screw, be tightened in the upper and lower closure plate that the screw rod two ends are used for clamping several electroplated workpiece, be connected with link plate in upper plugging plate upper end.

In the improvement project to above-mentioned parcel plating mold, described upper plugging plate is the T type; This lower plugging plate is hollow shape, is screwed with the shutoff nut in the screw rod end that is positioned at below the lower plugging plate.

In the improvement project to above-mentioned parcel plating mold, be provided with the rubber ring that closely contacts with the electroplating parts of upper and lower end at that relative face of described upper and lower closure plate.

Compared with prior art, the invention has the beneficial effects as follows: 1), since it to be closure plate by being screwed in the double threaded screw two ends will be enclosed within the outer a plurality of electroplating parts of screw rod clamps, make side surface of workpiece and internal surface and electroplate liquid isolated fully, so just can only electroplate the workpiece outside surface, this not only can improve the efficient of parcel plating; And after electroplating, need not process again the side and the internal surface that do not need to electroplate, thereby neither can waste plated material, can save production cost again, of the present invention rational in infrastructure as can be seen; 2), in addition, its easy disassembly, reusable, the intact a collection of plated item of every plating is changed newly a collection of again.

The present invention is described in further detail below in conjunction with accompanying drawing and embodiment:

Fig. 2 is the assembling synoptic diagram of the embodiment of the invention;

Fig. 3 is the structural representation of the use state of the embodiment of the invention.

[embodiment]

The present invention is a kind of parcel plating mold, as shown in Figure 1, 2, 3, its include long strip type double threaded screw 1, be tightened in the upper and lower closure plate 3,4 that screw rod 1 two ends are used for clamping several electroplated workpiece 2, be connected with link plate 4 in upper plugging plate 3 upper ends, the whole electroplating parts that to electroplate the gripping of mold institute by link plate 4 are immersed in the electroplate liquid, so just can electroplate a plurality of (in batches) electroplating parts simultaneously, whenever process the lower plugging plate 4 of back-outing after a collection of and take out and finish workpiece and put new workpiece to be plated again.As can be seen, the present invention clamps being enclosed within the outer a plurality of electroplating parts of screw rod by wearing the closure plate that is screwed in the double threaded screw two ends, make side surface of workpiece and internal surface and electroplate liquid isolated fully, so just can only electroplate the workpiece outside surface, this not only can improve the efficient of parcel plating; And after disposable plating, need not process again the side and the internal surface that do not need to electroplate, thereby neither can waste plated material, can save production cost again; And the parcel plating mold is reusable, assembles easy to usely, and the intact a collection of plated item of every plating is changed newly a collection of again.

In the present embodiment, as shown in Figure 1, described upper plugging plate 3 is the T type, and lower plugging plate 4 is hollow shape, is screwed with shutoff nut 6 in the screw rod end that is positioned at below the lower plugging plate 4, and certainly, lower plugging plate 4 also can resemble and be the T type the upper plugging plate.

As shown in Figure 3, be provided with respectively the

rubber rings

7,8 that closely contact with the electroplating parts 2 of upper and lower end at described upper and lower closure plate 3,4 those relative faces, the workpiece face that need not to electroplate with good seal better.Between lower plugging plate and shutoff nut, also be provided with rubber ring 9.

Claims

1. parcel plating mold is characterized in that: comprise long strip type double threaded screw (1), be tightened in the upper and lower closure plate (3,4) that the screw rod two ends are used for clamping several electroplated workpiece (2), be connected with link plate (4) in upper plugging plate (3) upper end.

2. parcel plating mold according to claim 1, it is characterized in that: described upper plugging plate (3) is the T type; This lower plugging plate (4) is hollow shape, is screwed with shutoff nut (6) in the screw rod end that is positioned at lower plugging plate (4) below.

3. parcel plating mold according to claim 1 and 2 is characterized in that: be provided with respectively the rubber ring (7,8) that closely contacts with the electroplating parts (2) of upper and lower end at that relative face of described upper and lower closure plate (3,4).
