Description

Technical Field

[0001] The utility model relates to the technical field of mold exhaust, in particular to an anti - shedding and quick - replacement exhaust plug device for casting molds. Background Art

[0002] At present, most of the exhaust plugs of low - pressure molds adopt conventional strip - shaped exhaust plugs, or conventional cross - shaped exhaust columns, or conventional exhaust needles, or conventional exhaust needles with wire - cut exhaust grooves.

[0003] 1. When the conventional strip - shaped exhaust plug is knocked into the mold exhaust hole, the exhaust gaps are easily squeezed together, resulting in the blockage of the exhaust gap or deformation, which causes the exhaust gap to become larger and is likely to enter aluminum during production;

[0004] 2. When knocking the exhaust plug of the conventional cross - shaped exhaust column, if the exhaust plug hole is small when the mold is cold, it is difficult to knock it in, resulting in the squeezing together of the exhaust gaps and affecting the exhaust effect. If the exhaust plug hole is slightly larger when knocking it in when the mold is cold, it is likely to fall out after the mold temperature rises during production, causing aluminum to enter the exhaust plug hole and affecting production;

[0005] 3. The exhaust effect of the conventional exhaust needle is not good, which affects the production cycle of the mold;

[0006] 4. For the conventional exhaust needle with wire - cut exhaust grooves, the exhaust effect is acceptable, but the cost is high, it is easy to deform, and it is not suitable for mass use. Content of the Utility Model

[0027] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0028] The present utility model provides a device for preventing the shedding and quickly replacing the exhaust plug of a casting mold. Please refer to Figures 1-4 , which includes a fixing rod 100 and an exhaust plug component 200;

[0029] Please continue to refer to Figure 1 , Figure 3 and Figure 4 , the fixing rod 100 as a connecting base is set corresponding to the mold. A connecting groove 120 is opened at the top of the fixing rod 100, and an exhaust groove 121 is opened at the inner bottom of the connecting groove 120. The bottom of the fixing rod 100 is connected with a base 110, and the base 110 is set corresponding to the mold;

[0030] Please continue to refer to Figures 1-4 , the exhaust plug component 200 is placed on the fixing rod 100 and set corresponding to the connecting groove 120 to exhaust the mold;

[0031] The exhaust plug component 200 includes an exhaust plug 210 rotatably connected to the connecting groove 120. A hexagonal groove 211 is opened at the top of the exhaust plug 210, and an indicating groove 212 is opened at the inner bottom of the hexagonal groove 211 (the hexagonal groove is adapted to a hexagonal wrench to rotate and adjust the exhaust plug, and the indicating groove represents the direction of the exhaust groove). A connecting seat 220 is integrally formed at the bottom of the exhaust plug 210. Arc-shaped corners 221 are integrally formed on the left and right sides of the connecting seat 220. Cutting surface grooves 222 are opened on both the front and rear sides of the exhaust plug 210;

[0032] Furthermore, the connecting groove 120 is wedge-shaped (similar to a trapezoidal structure in cross-section, and the shape of the arc-shaped corner fits the left and right side surfaces in the connecting groove), and when the connecting seat 220 rotates, the connection state between the exhaust plug 210 and the connecting groove 120 is controlled by the arc-shaped corner 221 and the cutting surface groove 222;

[0033] Action:

[0034] Rotate the connecting seat 220. When the arc-shaped corner 221 completely fits the connecting groove 120, the exhaust plug 210 is locked at the top of the fixed rod 100 at this time;

[0035] When the exhaust plug 210 needs to be replaced, rotate the connecting seat 220 until the arc-shaped corner 221 separates from the connecting groove 120. At this time, the cutting surface groove 222 is arranged corresponding to the left and right sides of the connecting groove 120 to separate the exhaust plug 210 from the fixed rod 100;

[0036] Furthermore, a hexagonal groove 211 is formed at the top of the exhaust plug 210, and an indicating groove 212 is formed at the bottom inside the hexagonal groove 211;

[0037] Working principle: When the utility model is in use, the manufactured exhaust plug 210 is installed on the fixed rod 100 and installed on the mold from the bottom of the mold upward, ensuring that the exhaust plug and the mold cavity surface are smoothly cut, easy to install, easy to disassemble, stable and not falling off, and the exhaust effect is good. If individual exhaust plugs are blocked during the production process, the exhaust plug 210 can be rotated with a hexagonal wrench, so that the exhaust plug 210 is in a loose state with the connecting groove 120, and then the exhaust plug 210 is taken out and a new exhaust plug is replaced. During installation, the exhaust plug 210 is rotated in the reverse direction.

[0038] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
