Description

A curtain wall hidden frame semi-briquetting block and its mold manufactured by die-casting technology

technical field

The utility model relates to the technical field of building curtain walls, in particular to a half-briquetting block of a hidden frame of a curtain wall manufactured by a die-casting process and a mold thereof.

Background technique

The existing curtain wall hidden frame semi-briquetting generally requires the profile factory to extrude and open the mold to produce aluminum profiles, and process the profiles into required products in the workshop according to the processing drawings. The processing cost is high and the process is relatively complicated, especially the waste of profiles is serious . Die casting (English: casting) is a metal casting process, which is characterized by using a mold cavity to apply high pressure to molten metal. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings are ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. The castings produced by the die-casting process have the advantages of excellent dimensional accuracy, high material utilization rate and simple process.

To achieve the above object, the utility model takes the following technical solutions:

A curtain wall hidden frame semi-pressing block manufactured by die-casting technology, which includes a plate-shaped body, one end of the body extends outwards with a boss, and the other end has a pressing part on the same side as the boss; a connecting hole runs through The body and the boss, the connecting hole is provided with an annular pit at the end of one side of the body; the upper and lower ends of the boss respectively extend an inserting block axially along the connecting hole, and the two inserting blocks are respectively located at the The upper end and the lower end of the connection hole; the side faces of each plug gradually shrink inward so that there is a first draft angle between the side of the plug and the axis of the plug.

Further, the side surface of the boss shrinks inward gradually so that there is a second draft angle between the side surface of the boss and the axis of the boss.

Further, the first draft angle and the second draft angle are both 0.5-1 degree.

Preferably, both the first draft angle and the second draft angle are 0.5 degrees.

Preferably, the pressing portion has a semicircular cross section.

A mold for a half-pressed block of a hidden frame of a curtain wall manufactured by a die-casting process, which includes a movable mold and a fixed mold. corresponding to the configuration.

Further, the parting surfaces of the movable mold and the fixed mold are located on the outer side of the boss of the half-pressing block of the hidden frame of the curtain wall.

The beneficial effects of the utility model are: the curtain wall hidden frame semi-briquetting block and its mold manufactured by the die-casting process of the utility model have the advantages of simple structure, low cost and high process dimension precision.

Detailed ways

The utility model is described in detail through specific examples below, but it is not intended to limit the scope of implementation of the utility model.

As shown in Fig. 1-Fig. 6, the utility model provides a curtain wall hidden frame semi-briquetting block manufactured by die-casting process, which includes a plate-shaped body 1, a boss 2 extending outward from one end of the body 1, and a boss 2 at the other end. The pressing portion 3 located on the same side as the boss 2 preferably has a semicircular cross section. A connection hole 4 runs through the body 1 and the boss 2 , and an annular recess 5 is formed at the end of the connection hole 4 on one side of the body 1 for matching with the end of a screw. The upper and lower ends of the boss 2 respectively extend an inserting block 6 axially along the connecting hole 4 , and the two inserting blocks 6 are respectively located at the upper end and the lower end of the connecting hole 4 . The sides of each insert block 6 shrink inward gradually so that there is a first draft angle between the side of the insert block and the axis of the insert block. The first draft angle is 0.5-1 degree, preferably 0.5 degree. In addition, the side of the boss 2 gradually shrinks inward so that there is a second draft angle between the side of the boss 2 and the axis of the boss 2 . The second draft angle is 0.5-1 degree, preferably 0.5 degree. The first draft angle and the second draft angle can facilitate the demoulding of the product when the die is drawn in the die-casting process.

As shown in Figure 7, the utility model also provides a die-casting process for the curtain wall hidden frame semi-briquetting mold, which includes a fixed mold 7 and a movable mold 8, the fixed mold 7 and the movable mold 8 are connected to form a mold cavity 9. The spatial shape of the mold cavity 9 corresponds to the configuration of the half-briquetting block of the hidden frame of the curtain wall. Preferably, the parting surfaces 10 of the fixed mold 7 and the movable mold 8 are located on the outer side of the boss 2 of the half-press block of the hidden frame of the curtain wall. According to the different sizes of the plug-in blocks, different movable molds 8 can be replaced, while the fixed mold 7 does not need to be replaced, which greatly saves the cost of mold opening. The mold of the present invention also includes necessary ejection structures, exhaust structures, pouring structures, etc. (not shown in the figure), which are prior art, and will not be repeated here.

In summary, the utility model has the following advantages:

1. The utility model adopts another processing technology——die-casting, so that the components can be formed by one-time die-casting, which reduces the process flow of designing drawings, picking up materials, and reprocessing in the factory, reduces costs, and reduces the amount of profiles and processing technology. The remaining material is wasted and the material cost is saved.

2. The utility model processes the semi-briquetting block into a standard part, which is a complete product upon arrival from the casting mold manufacturer. It does not need to be extruded by the profile manufacturer to open the mold and transported to the processing workshop, and then undergoes secondary processing in the processing workshop, reducing the number of component processing links. The production cycle is shortened, the management cost is reduced, and the product processing precision is high, which plays a positive role in ensuring the construction period and quality of the entire project.

3. The semi-briquetting of the utility model is completed in an outsourcing factory, and the semi-briquetting is processed and stored according to standardization, the labor cost and transportation cost are greatly reduced, the management cost is reduced, and the production and supply are easy to handle, improving efficiency.

4. The utility model adopts die-casting mold opening processing technology, and the appearance of the profile is inclined with a certain angle in the drawing direction to facilitate drawing and forming.

The utility model is defined by the claims. But based on this, those skilled in the art can make various obvious changes or modifications, all of which should be within the main spirit and protection scope of the present utility model.
