Abstract

The invention discloses a mold for injection molding of concave characters on joint parts. A cavity consistent with the external dimensions of the required injection molded parts is formed by setting a first groove, a second groove, and a concave mold, and the mold cavity is formed in the second concave The mold is provided with a plurality of concave character models required for circular arc distribution along the circumferential surface, and these character models are reversely embedded on the circumferential surface of the second groove, and injected into the above-mentioned cavity When the liquid is injected, while the required joint parts are obtained, these character models form clear concave characters on the parts, and at the same time, the production efficiency is greatly improved compared with the prior art.

Description

Mold for injection molding of recessed characters on connector parts

technical field

The invention relates to a mold used for injection molding concave characters on joint parts.

Background technique

It is often necessary to mark the model or other information on the parts, such as common joint parts, so that it is easy to find during subsequent installation or replacement. The general method is to take out the parts after casting and use the model of the corresponding characters to make them The surface of the part is deformed to form concave characters. This method is not only low in processing efficiency, but also the definition of the concave characters formed under this processing method for parts with arc-shaped surfaces is uneven. In addition, the instability of manual force is also It will cause the formed concave characters to be unclear.

Contents of the invention

The object of the present invention is to provide a mold for the injection molding of concave characters on joint parts to directly obtain the concave characters on the joint parts.

In order to achieve the above object, the technical solution adopted by the present invention is: a mold for injection molding of concave characters on joint parts, including a movable template, a fixed template that can closely cooperate with the movable template to form a closed cavity, and a fixed template that can be closely matched with the movable template. The template is fixedly connected with the movable mold base, and the taking module can be arranged on the movable mold base up and down. The first groove corresponding to the die, the die is matedly inserted in the bottom of the first groove, the fixed plate is correspondingly provided with a second groove, the first groove, the The second groove and the concave mold cooperate to form a cavity consistent with the external dimensions of the joint parts, and the second groove is also provided with a plurality of character models distributed in arcs along the circumferential surface. , the character model is inlaid on the circumferential surface of the second groove in reverse.

Preferably, the fixed template and the concave mold are correspondingly opened with open third grooves and fourth grooves, and the fixed template is provided with a groove that can be inserted into the third groove and the fourth groove in the ferrule.

Further preferably, a pressing block is further arranged on the fixed plate, and the ferrule is fixedly connected on the lower surface of the pressing block.

Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: by setting the first groove, the second groove, and the die to form a cavity consistent with the external dimensions of the required injection molding parts, and in the second The second concave mold is provided with a plurality of concave character models required for circular arc distribution along the circumferential surface, and these character models are reversely embedded on the circumferential surface of the second groove, and then to the above-mentioned cavity When the injection molding liquid is injected in the middle, while obtaining the required joint parts, these character models form clear concave characters on the parts, and at the same time, the production efficiency is greatly improved compared with the existing technology.

Detailed ways

The structure of the present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 2-4, a mold for injection molding of concave characters on joint parts includes a movable template 2, a fixed template 3 that can closely cooperate with the movable template 2 to form a closed cavity, and is fixedly connected with the movable template 2. The moving die base 1, the taking module 4 that can be arranged on the moving die base 1 up and down, the upper end surface of the taking module 4 is fixedly connected with a die 6, and the movable die plate 2 is provided with a corresponding die 6 The first groove, the die 6 are matedly inserted in the bottom of the first groove, and the fixed template 3 is correspondingly provided with a second groove, so that the first groove, the second groove, and the die 6 are matched to form A cavity that is consistent with the external dimensions of the joint parts to be injected is formed, and a plurality of character models 7 of required concave characters distributed in a circular arc are protruded on the circumferential surface of the second groove, and these character models 7 are in the form of Reversely set on the circumferential surface of the second groove, of course, these character models 7 can also be reversely set on the circumferential surface of the first groove, but it is arranged on the second concave of the fixed template 3 The groove can make it more convenient to take out the parts when the mold is opened after the parts are injected. In this way, the movable template 2 cooperates with the fixed template 3 to form a closed cavity, and the injection liquid is injected into the cavity to form the joint parts to be injected, in which the corresponding characters are formed at the corresponding positions. The recessed characters in the parts. The character model 7 can be combined according to actual needs and then set on the circumferential surface of the first groove or the second groove. By using the injection mold, clearly visible concave characters can be obtained on the joint parts. Compared with the existing Technology has dramatically increased productivity.

Referring to Figures 1-4, there is a groove in the middle of the joint part, so the fixed template 3 and the die 6 are correspondingly provided with an open third groove and a fourth groove 9, which are set on the fixed template 3. The ferrule 8 that can be inserted into the above-mentioned third groove and the fourth groove 9 can form corresponding grooves on the injection molded joint parts. In this embodiment, the fixed template 3 is also provided with a pressing block 5 , the ferrule 8 is fixedly connected and arranged on the lower surface of the pressing block 5 .

The above embodiments are only to illustrate the technical concept and characteristics of the present invention. All equivalent changes or modifications shall fall within the protection scope of the present invention.
