The provided air conditioner chassis punching and embossing die can be used to produce a variety of similar chassis components, which can reduce the number of air conditioner chassis punching and embossing dies to be made, reduce production costs and management costs, and meet the needs of rapid production of new products;

[0004] For example, the sheet metal mold with the publication number CN110560571B relates to the sheet metal technology field, and is used to avoid pinching of raw materials without changing the original material taking method to improve production efficiency and production quality. The sheet metal mold of the present invention includes a first stripper plate, a first template and a sliding mechanism. By setting the sliding mechanism, the sliding mechanism moves toward the direction close to the first template in the mold opening state to cover the gap between the first stripper plate and the first template. Therefore, during the material taking process, even if the material taking operator does not take out the raw materials in the vertical direction, the raw materials will not be pinched in the gap between the first stripper plate and the first template, because the problem of difficulty in taking out materials and pinching of the full-circle flanging mold parts is solved, thereby improving the production efficiency and quality of the product;

[0012] Furthermore, a cooling groove is provided inside the mold base, and the position of the cooling groove corresponds to the water injection port.

[0013] Furthermore, the pressing and fitting mechanism is provided with a movable block, and the movable block is installed through the surface of the second positioning rod, and an adjusting rod is rotatably installed on the inner side of the movable block, and a contact plate is rotatably installed on the inner side of the adjusting rod.

[0014] Furthermore, a return spring is nested on the surface of the second positioning rod, and the left and right ends of the return spring are fixedly installed between the movable block and the fixed plate, and a damping rod is arranged between the fixed plate and the contact plate.

[0015] Furthermore, a telescopic bellows is installed through the interior of the movable mold, and the upper end of the telescopic bellows is connected to the positioning groove, and the lower end of the telescopic bellows is installed through the upper end of the auxiliary airbag, and the outer side of the auxiliary airbag is fixedly installed on the inner side of the fixed plate, and the inner side of the auxiliary airbag fits the contact plate.

[0016] Furthermore, the knocking and debubble mechanism is provided with a water wheel rod, and the water wheel rod is rotatably installed inside the movable mold, and the water wheel rod is located inside the water injection port, and cams are fixedly installed on the outer ends of both sides of the water wheel rod.

[0017] Furthermore, a limiting bin is fixedly installed on the outer side of the movable mold, and an inflatable airbag is fixedly installed inside the limiting bin, and the material of the inflatable airbag is elastically set, and an extrusion block is nested and installed at the front end of the limiting bin, the shape of the extrusion block is inclined, and the inner side of the extrusion block is slidably connected to the inside of the limiting bin through a slider slot, and the extrusion block and the cam correspond to each other, and a one-way air inlet is installed through the lower end of the inflatable airbag, and a one-way valve is fixedly installed inside the one-way air inlet.

[0018] Furthermore, an air guide hose is installed through the inner side of the inflatable airbag, and the upper end of the air guide hose is installed through the upper end of a knocking bin, a rotating rod is rotatably installed inside the knocking bin, and a knocking block is rotatably installed on the surface of the rotating rod, and the output end of the air guide hose is aligned with the upper wind receiving plate of the knocking block.

[0019] Further, the method specifically includes the following steps:

[0020] S1: When the molding die is used, the hydraulic rod is started, and the hydraulic rod drives the upper movable die to move downward, so as to close the die seat. After the movable die and the die seat are closed, the liquid metal material is cast through the casting port. At this time, the liquid metal material falls into the mold groove through the casting port for shaping. After shaping, cooling water is added through the water injection port. The cooling water enters the cooling groove inside the mold seat through the water injection port to cool the mold. At the same time, the cooling water is filtered with the filter plate embedded in the water injection port, so that sewage can be used for cooling to reduce resource consumption and avoid blockage inside the mold, so as to achieve the effect of rapid cooling, and enable the electronic throttle to be quickly molded;

[0021] S2: When the movable mold and the mold base are installed, a pressing structure is provided on the inner side of the fixed plate outside the mold base, and a return spring is provided on the inner side of the fixed plate. The return spring pushes the movable block on the surface of the second positioning rod through its own elastic force, and the movable block slides along the second positioning rod. At this time, the movement of the movable block drives the adjusting rod inside it, and the adjusting rod pushes the contact plate through its own rotation, so that the contact plate squeezes the movable mold inward, so that the movable mold is further limited, and at the same time, the damping rod between the contact plate and the fixed plate is cooperated, so that the structure has a shock-absorbing effect, and the shaking of the movable mold during casting causes the displacement, so that the shock-absorbing effect can be achieved. The positioning groove at the bottom of the movable mold is embedded along the first positioning rod. When the positioning groove is embedded in the surface of the first positioning rod, since the first positioning rod and the positioning groove can be sealed and fitted, the air inside the positioning groove is squeezed into the interior of the telescopic bellows by the first positioning rod, and the air entering the interior of the telescopic bellows enters the interior of the auxiliary airbag along the telescopic bellows. The auxiliary airbag expands after being inflated, so as to push and support the contact plate, thereby achieving a secondary support effect and improving the connection stability between the mold base and the movable mold;

[0022] S3; When cooling water is injected through the water inlet, the cooling water contacts the water wheel rod, and the impact force of the water flow drives the water wheel rod to rotate. The rotation of the water wheel rod drives the cam on the outside to rotate. The rotation of the cam squeezes the extrusion block on the outside of the limit bin. Since the extrusion block is inclined in shape, it can be pushed along the inside of the limit bin to squeeze the inflatable airbag under the rotation and squeezing of the cam. The inflatable airbag is squeezed to transport the air inside to the knocking block inside the knocking bin through the air guide hose. The knocking block is rotatably installed inside the knocking bin due to the setting of the rotating rod, and the air guide hose The air outlet is aligned with the upper air receiving plate of the knocking bin, so that the knocking block can be blown to swing back and forth under the blowing of the air guide pipe, and the movable mold is knocked when the knocking block swings back and forth. At the same time, when the extrusion block stops being squeezed by the cam, the extrusion block is reset under the elastic action of the inflatable airbag. At the same time, the inflatable airbag is inflated through the one-way air inlet at the bottom. The one-way valve arranged inside the one-way air inlet can only take in air, so as to achieve the effect of reciprocating use, thereby achieving the effect of vibration to remove bubbles, and avoiding the accumulation of bubbles inside during casting, resulting in holes, so as to achieve a high-precision effect.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. When using the molding die, the hydraulic rod is started, which drives the upper movable die to move downward. The cooling water is injected into the cooling groove inside the die seat through the water injection port to cool the die. At the same time, the cooling water is filtered with the filter plate embedded in the water injection port. In this way, sewage can be used for cooling to reduce resource consumption and avoid blockage inside the die, so as to achieve the effect of rapid cooling and enable the electronic throttle to be quickly molded.

[0025] 2. When the movable mold and the mold base are installed, a pressing structure is provided on the inner side of the fixed plate outside the mold base, so that the movable mold is further limited. At the same time, the damping rod between the contact plate and the fixed plate is used to make the structure have a shock-absorbing effect, so as to avoid the shaking of the movable mold during casting and cause deviation, so as to achieve the shock-absorbing effect;

[0026] Furthermore, the positioning groove at the bottom of the movable mold is embedded along the positioning rod. When the positioning groove is embedded in the surface of the positioning rod, the positioning rod and the positioning groove can be sealed and fitted, so that the air inside the positioning groove is squeezed into the interior of the telescopic bellows by the positioning rod, and the air entering the interior of the telescopic bellows enters the interior of the auxiliary airbag along the telescopic bellows. The auxiliary airbag expands after being inflated, thereby pushing and supporting the contact plate, achieving a secondary support effect, and improving the connection stability between the mold base and the movable mold;

[0027] 3. When cooling water is injected through the water inlet, the cooling water contacts the water wheel rod, and the impact force of the water flow drives the water wheel rod to rotate. The rotation of the water wheel rod drives the cam on its outside to rotate, which can blow the knocking block to swing back and forth. The knocking block knocks on the movable mold when it swings back and forth. At the same time, when the extrusion block stops being squeezed by the cam, the extrusion block is reset under the elastic action of the inflatable airbag. At the same time, the inflatable airbag is inflated through the one-way air inlet at the bottom. The one-way valve arranged inside the one-way air inlet can only take in air, thereby achieving the effect of reciprocating use, thereby achieving the effect of vibration to remove bubbles, and avoiding the accumulation of bubbles inside during casting, resulting in holes, thereby achieving a high-precision effect.

4. The method for forming a high-precision electronic throttle body molding die according to claim 3, characterized in that: The specific steps include: S1: When the molding die is used, the hydraulic rod (2) is started, and the hydraulic rod (2) drives the upper movable die (3) to move downward, thereby closing the die seat (1). After the movable die (3) and the die seat (1) are closed, liquid metal material is cast through the casting port (4). At this time, the liquid metal material falls into the mold groove (5) through the casting port (4) to be shaped. After shaping, cooling water is added through the water injection port (8). The cooling water enters the cooling groove (10) inside the mold seat (1) through the injection port (8) to cool the mold. At the same time, the cooling water is filtered with the help of a filter plate (9) embedded in the water injection port (8). In this way, sewage can be used for cooling, thereby reducing resource consumption and avoiding blockage inside the mold, thereby achieving a rapid cooling effect, and enabling the electronic throttle to be quickly molded. S2: When the movable mold (3) is installed on the mold base (1), a pressing structure is provided on the inner side of the fixed plate (11) outside the mold base (1), and a return spring (14) is provided on the inner side of the fixed plate (11). The return spring (14) pushes the movable block (13) on the surface of the second positioning rod (12) by its own elastic force, and the movable block (13) slides along the second positioning rod (12). At this time, the movement of the movable block (13) drives the adjustment rod (15) inside it. The adjustment rod (15) pushes the contact plate (17) by its own rotation, so that the contact plate (17) presses the movable mold (3) inward, so that the movable mold (3) is further limited. At the same time, the damping rod (16) between the contact plate (17) and the fixed plate (11) is cooperated to make the structure The invention has a shock-absorbing effect, and avoids the movable mold (3) from shaking and causing deviation during casting, so as to achieve the shock-absorbing effect. The positioning groove (7) at the bottom of the movable mold (3) is embedded along the first positioning rod (6). When the positioning groove (7) is embedded in the surface of the first positioning rod (6), the first positioning rod (6) and the positioning groove (7) can be sealed and fitted, so that the air inside the positioning groove (7) is squeezed into the inside of the telescopic bellows (18) by the first positioning rod (6). The air entering the inside of the telescopic bellows (18) enters the inside of the auxiliary airbag (19) along the telescopic bellows (18). The auxiliary airbag (19) expands after being inflated, thereby pushing and supporting the contact plate (17), achieving the effect of secondary support, and improving the connection stability between the mold base (1) and the movable mold (3); S3; when cooling water is injected through the water injection port (8), the cooling water contacts the water wheel rod (20), and the impact force of the water flow drives the water wheel rod (20) to rotate. The rotation of the water wheel rod (20) drives the cam (21) on the outside thereof to rotate. The rotation of the cam (21) squeezes the extrusion block (24) on the outside of the limit bin (22). Since the extrusion block (24) is in an inclined shape, it can be pushed along the inside of the limit bin (22) to squeeze the inflatable airbag (23) under the rotation and squeezing of the cam (21). The inflatable airbag (23) is squeezed to transport the air inside to the knocking block (28) inside the knocking bin (26) through the air guide hose (25). The knocking block (28) is installed on the knocking bin (26) due to the setting of the rotating rod (27). The interior of the chamber (26), and the air outlet of the air guide hose (25) is aligned with the upper air receiving plate of the knocking chamber (26), so that the knocking block (28) can be blown to swing back and forth under the blowing of the air guide pipe, and the knocking block (28) knocks the movable mold (3) when swinging back and forth. At the same time, when the extrusion block (24) stops being squeezed by the cam (21), the extrusion block (24) is reset under the elastic action of the inflatable airbag (23), and at the same time, the inflatable airbag (23) is inflated through the one-way air inlet (29) at the bottom. The one-way valve arranged inside the one-way air inlet (29) can only take in air, so as to achieve the effect of cyclic reciprocating use, thereby achieving the effect of vibration to remove bubbles, and avoiding bubbles from accumulating inside during casting, resulting in holes, so as to achieve a high-precision effect.
