Abstract

The utility model provides a die face inserts formula high utilization rate mould. It relates to a die, in particular to an improvement on a die insert. The die surface insert type high-utilization-rate die is provided, wherein the insert is connected with the die more tightly, and the insert is not easy to eject. The die comprises a die body, wherein an insert is fixed on the die body through a fixing piece detachable, the fixing piece comprises a guide strip arranged on the insert, the guide strip is in a table shape with a large top and a small bottom, the sectional area of one end of the insert is far away from the guide strip and is smaller than that of the end of the insert, a plurality of parallel mounting grooves are uniformly distributed on the guide strip, sealing rings are arranged in the mounting grooves, and the insert is pressed into the die body through high-pressure gas. The interference fit between the insert and the die can be kept all the time in the casting process, and even if the pressure in the die cavity is overlarge, the insert can be pressed in the insert jack through extra air pressure, so that the die cavity is still a closed cavity, and the metal in a molten state is prevented from leaking.

Description

Die face insert type high-utilization-rate die

Technical Field

The utility model relates to a mould especially relates to the improvement of inserting to the mould.

Background

Generally, when a mold is used for changing the detailed structure of a casting part in the molding process of the casting part, an insert is inserted into the mold to change the detailed structure of the casting part, the insert is inserted into a hole reserved in the mold through interference fit, and the interference fit is actually realized through gravity striking, but the insert is difficult to take out when the insert needs to be taken out, or the insert is easy to eject when the pressure in a mold cavity is too high, so that the casting failure is caused. Affecting the casting schedule.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides an insert the die face that is connected inseparabler with the mould, inserts difficult quilt and inserts formula high utilization rate mould.

The utility model discloses a following technical scheme realizes: die face inserts formula high usage mould, including the mould body, inserts and fixes on the mould body through mounting detachable, the mounting is including locating the conducting bar on inserting, the conducting bar is big-end-up's platform form, the conducting bar is kept away from the sectional area of the one end of inserting is less than the conducting bar is close to the sectional area of the one end of inserting, a plurality of parallel mounting grooves of equipartition on the conducting bar, the built-in sealing washer of mounting groove, insert and impress through high-pressure gas this is internal to the mould.

The die is characterized in that the die body is provided with an insert inserting hole, the insert inserting hole is matched with the guide strip, and the insert inserting hole is in an inverted trapezoid shape with a large opening and a small bottom.

The insert block further comprises a base, the guide strip is fixed on the base, a jacking hole is formed in the end face of the base, a piston rod is arranged in the jacking hole, the piston rod is hollow, and a rod body of the piston rod is connected with a high-pressure air source.

Compared with the prior art, the utility model discloses high pressurized air source can be provided by the air compressor machine, and the air compressor machine provides gas when needs withstand, makes the downthehole inflation of whole jacking, under the inclosed effect of piston, along with the downthehole atmospheric pressure grow of jacking, insert and move to mould direction top more, just can remain throughout in the casting process insert and the interference fit between the mould, even the pressure in the die cavity is too big, also can will insert through extra atmospheric pressure and press in inserting the jack, make the die cavity still be a closed cavity, prevent the metal leakage of melting state.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1. a base; 2. conducting bars; 3. a piston rod; 4. and (6) jacking holes.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1, the die surface insert type high utilization rate die comprises a die body, an insert is detachably fixed on the die body through a fixing piece, the fixing piece comprises a guide strip 2 arranged on the insert, the guide strip 2 is in a table shape with a large top and a small bottom, the sectional area of one end, far away from the insert, of the guide strip 2 is smaller than the sectional area of one end, close to the insert, of the guide strip 2, a plurality of parallel mounting grooves are uniformly distributed on the guide strip 2, sealing rings are arranged in the mounting grooves, and the insert is pressed into the die body through high-pressure gas. The high-pressure gas can be taken from the air compressor, and when the pressure in the die cavity is too high, the high-pressure gas can provide extra pressure to press the insert, so that the insert is still pressed in a state of interference fit with the die cavity, and molten metal in the die cavity is prevented from flowing out.

The die is characterized in that an insert inserting hole is formed in the die body and matched with the guide strip 2, and the insert inserting hole is of an inverted trapezoid shape with a large opening and a small bottom. When the insert is inserted, the guide strip 2 is directly matched with the insert jack, is in interference fit with the insert jack under the action of extra air pressure and is connected more tightly, and even if the pressure in the die cavity is overlarge, the insert can be pressed in the insert jack through the extra air pressure, so that the die cavity is still a closed cavity, and molten metal leakage is prevented.

The insert further comprises a base 1, the guide strip 2 is fixed on the base 1, a jacking hole 4 is formed in the end face of the base 1, a piston rod 3 is arranged in the jacking hole 4, the piston rod 3 is hollow, and a rod body of the piston rod 3 is connected with a high-pressure air source. The high-pressure air source can be provided by the air compressor, when the air compressor provides air when needing to be supported, the whole jacking hole 4 is inflated, under the closed action of the piston, along with the increase of the air pressure in the jacking hole 4, the insert is pushed towards the direction of the mold, the interference fit between the insert and the mold can be always kept in the casting process, even if the pressure in the mold cavity is overlarge, the insert can be pressed in the insert inserting hole through extra air pressure, so that the mold cavity is still a closed cavity, and the metal leakage in a molten state is prevented.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
