Description

Technical Field

[0001] The utility model relates to the field of jig technology, in particular to a dot printing jig and a dot printing head thereof for preventing pressure damage. Background Art

[0002] After the silicone products are produced, it is necessary to print the production ink on the products, such as silicone buttons.

[0003] In the actual production process of dot-printing conductive ink, due to different product requirements, the conductive ink dot-printing positions are different, and the dot-printing area is small, resulting in a height difference between some dot-printing heads and the contacts of the silicone. Therefore, on the same dot-printing jig, the specifications of some dot-printing heads have height differences from other dot-printing heads. In addition, there will be errors in the production process of the dot-printing head, which makes the actual height of the dot-printing head slightly higher than the standard height. When the male mold is pressed down for dot-printing, this part of the dot-printing head will be subjected to very large force. At the same time, when the dot-printing area is small, the overall size of the dot-printing head is also small, resulting in the dot-printing head being relatively weak in strength. It is easy to deform under force when pressed down for dot-printing, and even collapse, resulting in a short service life. Therefore, it is necessary to improve the existing dot-printing heads. Utility Model Content

[0004] In view of this, the utility model aims to solve the deficiencies in the prior art, and its main purpose is to provide a dot printing jig and a dot printing head that can prevent damage by pressure, which can effectively solve the problem that when the overall size of the dot printing head is small and the strength is relatively weak, it is easy to be deformed by force when pressing down for dot printing, and even collapses, resulting in a short service life.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pressure-proof dot printing head comprises a fixing part, an elastic part and a dot printing body; the upper end of the elastic part is connected and fixed to the lower end of the fixing part; the dot printing body is connected and fixed to the lower end of the elastic part.

[0007] As a preferred solution, the fixing member is a headless screw.

[0008] As a preferred solution, the elastic member is a spring.

[0009] As a preferred solution, the dot printing body includes a hanging platform, a column and a dot printing part which are integrally formed and connected in sequence; the hanging platform is connected and fixed to the lower end of the elastic member, and the column is a column with a non-circular structure.

[0010] A dot printing jig includes a female mold and a male mold; the female mold is concavely provided with a receiving groove for placing a product, the male mold can be movably arranged above the female mold, a plurality of first dot printing heads are arranged on the lower surface of the male mold, a plurality of fixing holes are opened on the lower surface of the male mold, and the aforementioned anti-pressure dot printing head can be detachably installed in each fixing hole. The detachable structure makes it possible to replace a damaged dot printing head separately, saving costs, and the dot printing body extends downward from the fixing hole.

[0011] As a preferred solution, the plurality of first dot printing heads are arranged in a matrix on the lower surface of the male mold, and the plurality of fixing holes are also arranged in a matrix on the lower surface of the male mold.

[0012] As a preferred solution, a guide hole penetrating the surface of the male mold is provided on the male mold, and a guide column is protruding from the upper surface of the female mold. When the male mold moves up and down, the guide column enters or leaves the guide hole.

[0013] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0014] The fixing part and the dot printing body are elastically connected and fixed by an elastic part. By utilizing the compressible and resilient characteristics of the elastic part, it is ensured that the dot printing body can retreat when subjected to excessive pressure, and will not be deformed by force, thereby avoiding the problem of the dot printing head being crushed and extending the service life of the dot printing head. At the same time, it is ensured that the dot printing head can return to the set position when not subjected to pressure, thereby ensuring the amount of oil hanging on the side wall and the dot printing effect.
