[0002] Aluminum low-pressure mold is a type of mold that uses lower pressure for molding or casting. Compared with traditional molds, low-pressure molds usually use lower injection pressure, so that the mold will not generate excessive pressure during the molding process, thereby reducing the risk of mold wear and breakage.

[0003] The existing Chinese patent with application number CN202023188410.3 discloses an aluminum alloy low-pressure casting protection device, including a sealing cover, which is arranged on the casting platform through a sealing component, and a sealed space for accommodating the casting assembly is formed between the sealing cover and the casting platform; the sealing cover is connected to a protective gas intake component and a pressure relief valve, and protective gas is transported into the sealed space through the protective gas intake component, and the air in the sealed space is discharged through the pressure relief valve using the protective gas.

[0004] With regard to the existing related technologies, it is believed that the following defects often exist: when the sealing ring enters the sealing layer, relying solely on the sealing ring to be placed in the sealing groove will result in poor sealing effect. At the same time, the working environment in the factory is poor, and dust and impurities are easily accumulated in the sealing layer, thereby affecting the sealing effect of the sealing ring. Therefore, in response to the above problems, a low-pressure mold protection device for aluminum parts is proposed. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the above-mentioned problems, the utility model provides a low-pressure mold protection device for aluminum parts.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a low-pressure mold protection device for aluminum parts described in the utility model comprises a casting platform, a sealing cover is provided on the top of the casting platform, a sealing block is fixedly installed on the bottom of the sealing cover, a sealing groove is provided on the top of the casting platform, a through groove connected to the sealing groove is provided on the bottom of the casting platform, a plurality of receiving grooves connected to the sealing groove are provided inside the casting platform, two of the receiving grooves are symmetrically distributed about the central axis of the sealing groove, a sliding plate is sealingly and slidingly connected inside the receiving groove, a spring is fixedly installed inside the receiving groove, one end of the spring is fixedly connected to the sliding plate, a sliding block is fixedly installed on the end of the sliding plate away from the spring, an air outlet connected to the receiving groove is provided inside the casting platform, and the end of the air outlet away from the receiving groove is connected to the sealing groove; a guide component for assisting the sealing block to enter the sealing layer is provided on the top of the casting platform, and a dredging component for cleaning the through groove is provided at the bottom of the sealing block.

[0007] Furthermore, the top of the sliding block is inclined, and the inclined surface of the sliding block is rotatably connected to a plurality of rollers.

[0008] Furthermore, both sides of the bottom of the sealing block and both sides of the bottom of the sealing groove are inclined, and the sealing block is made of rubber.

[0009] Furthermore, the guide assembly includes two triangular guide blocks which are symmetrically arranged on the casting platform with respect to the central axis of the sealing groove, and the inclined surfaces of the guide blocks are rotatably connected to guide wheels.

[0010] Furthermore, the dredging assembly includes a conical dredging rod fixedly mounted on the bottom of the sealing block, and a plurality of scrapers are arranged on the surface of the dredging rod.

[0011] Furthermore, the scraper and the dredging rod are rotationally connected via a torsion spring, and the scraper is arc-shaped with a free end bent downward.

[0012] The utility model is beneficial in that:

[0013] 1. The utility model places the sealing block at the bottom of the sealing cover into the sealing groove of the casting platform. Since the sealing block is made of rubber, it will be squeezed and deformed when entering the sealing groove. The bottom inclined surface of the sealing block will first contact the inclined surface and roller of the sliding block. The inclined surface and roller of the sliding block will slide and shrink into the receiving groove after being squeezed, thereby facilitating the entry of the sealing block and reducing the resistance of the sealing block when entering. Since the sliding plate and the receiving groove are sealed and slidably connected, the sliding plate and the sliding block will squeeze the gas in the receiving groove when sliding and shrinking, so that the gas is blown into the sealing groove through the air outlet, and the dust and impurities in the sealing groove are blown to the through groove and discharged. When the sealing block enters the sealing groove for sealing, the dust and impurities in the sealing groove can be cleaned in advance. When the sealing block completely enters the sealing groove, it will fit tightly with the sealing groove, and at the same time, the side wall of the sliding block and the side wall of the sealing block will fit tightly, thereby achieving a better sealing effect, thereby achieving a better protection effect.

[0014] 2. The utility model uses the guide block and the guide wheel to guide the sealing block when the sealing block deviates when entering the sealing groove, so that the deviated sealing block can smoothly enter the sealing groove, thereby assisting the sealing block to quickly complete the insertion into the sealing groove for sealing.

[0024] See also Figure 1-6As shown, a low-pressure mold protection device for aluminum parts includes a casting platform 1, a sealing cover 2 is provided on the top of the casting platform 1, a sealing block 3 is fixedly installed on the bottom of the sealing cover 2, a sealing groove 4 is opened on the top of the casting platform 1, a through groove 5 connected to the sealing groove 4 is opened on the bottom of the casting platform 1, a plurality of receiving grooves 6 connected to the sealing groove 4 are opened inside the casting platform 1, two receiving grooves 6 are symmetrically distributed about the central axis of the sealing groove 4, a sliding plate 7 is sealingly and slidably connected inside the receiving groove 6, a spring 8 is fixedly installed inside the receiving groove 6, one end of the spring 8 is fixedly connected to the sliding plate 7, a sliding block 9 is fixedly installed on the end of the sliding plate 7 away from the spring 8, an air outlet 10 connected to the receiving groove 6 is opened inside the casting platform 1, and the end of the air outlet 10 away from the receiving groove 6 is connected to the sealing groove 4.

[0025] Specifically, the top of the sliding block 9 is inclined, and the inclined surface of the sliding block 9 is rotatably connected to a plurality of rollers 11. Both sides of the bottom of the sealing block 3 and both sides of the bottom of the sealing groove 4 are inclined, and the sealing block 3 is made of rubber.

[0026] During operation, the sealing block 3 at the bottom of the sealing cover 2 is placed into the sealing groove 4 of the casting platform 1. Since the sealing block 3 is made of rubber, it will be squeezed and deformed when entering the sealing groove 4. The bottom inclined surface of the sealing block 3 will first contact the inclined surface of the sliding block 9 and the roller 11. The inclined surface of the sliding block 9 and the roller 11 will slide and shrink into the receiving groove 6 after being squeezed, thereby facilitating the entry of the sealing block 3 and reducing the resistance of the sealing block 3 when entering. Since the sliding plate 7 and the receiving groove 6 are sealed and slidably connected, the sliding plate 7 and the sliding block 9 will squeeze the gas in the receiving groove 6 when sliding and shrinking, so that the gas is blown into the sealing groove 4 through the air outlet 10, and the dust and impurities in the sealing groove 4 are blown to the through groove 5 and discharged. When the sealing block 3 enters the sealing groove 4 for sealing, it can also pre-clean the dust and impurities in the sealing groove 4. When the sealing block 3 completely enters the sealing groove 4, it will fit tightly with the sealing groove 4. At the same time, the side wall of the sliding block 9 and the side wall of the sealing block 3 will fit tightly, thereby achieving a better sealing effect and thus a better protection effect.

[0027] A guide assembly for the auxiliary sealing block 3 to enter the sealing layer is arranged on the top of the casting platform 1. The guide assembly comprises two triangular guide blocks 12 symmetrically arranged on the casting platform 1 about the central axis of the sealing groove 4. The inclined surface of the guide block 12 is rotatably connected to a guide wheel 13.

[0028] During operation, when the sealing block 3 deviates when entering the sealing groove 4, it will contact the triangular guide block 12 and the guide wheel 13. The guide block 12 and the guide wheel 13 guide the sealing block 3 so that the deviated sealing block 3 can smoothly enter the sealing groove 4, thereby assisting the sealing block 3 to quickly complete the insertion into the sealing groove 4 for sealing.

[0029] The bottom of the sealing block 3 is provided with a clearing assembly for cleaning the through groove 5. The clearing assembly includes a conical clearing rod 14 fixedly installed at the bottom of the sealing block 3. A plurality of scrapers 15 are provided on the surface of the clearing rod 14. The scrapers 15 and the clearing rod 14 are rotatably connected by a torsion spring. The scrapers 15 are arc-shaped, and the free ends are bent downward.

[0030] During operation, when the sealing block 3 enters the sealing groove 4, it will enter the through groove 5 together with the dredging rod 14 and the scraper 15, and use the dredging rod 14 to dredge the through groove 5. At the same time, the scraper 15 on the surface of the dredging rod 14 is rotatably connected by a torsion spring, so one end of the scraper 15 is tightly fitted with the inner wall of the through groove 5. As the dredging rod 14 continues to move downward, the scraper 15 will also play a role in assisting in cleaning the inner wall of the through groove 5, thereby effectively reducing the dust and impurities remaining inside the through groove 5 and preventing the through groove 5 from being blocked.

[0031] Working principle: when the sealing block 3 deviates when entering the sealing groove 4, it will contact the triangular guide block 12 and the guide wheel 13. The guide block 12 and the guide wheel 13 guide the sealing block 3, so that the deviated sealing block 3 can smoothly enter the sealing groove 4, thereby assisting the sealing block 3 to quickly complete the insertion into the sealing groove 4 for sealing.

[0032] By placing the sealing block 3 at the bottom of the sealing cover 2 into the sealing groove 4 of the casting platform 1, since the sealing block 3 is made of rubber material, it will be squeezed and deformed to a certain extent when entering the sealing groove 4, and the bottom inclined surface of the sealing block 3 will first contact the inclined surface of the sliding block 9 and the roller 11, and the inclined surface of the sliding block 9 and the roller 11 will slide and shrink into the receiving groove 6 after being squeezed, thereby facilitating the entry of the sealing block 3 and reducing the resistance when the sealing block 3 enters. Since the sliding plate 7 and the receiving groove 6 are sealed and slidably connected, the sliding plate 7 and the sliding block 9 will squeeze the gas in the receiving groove 6 when sliding and shrinking, so that the gas is blown into the sealing groove 4 through the air outlet 10, and the dust and impurities in the sealing groove 4 are blown to the through groove 5 and discharged, and when the sealing block 3 enters the sealing groove 4 for sealing, the dust and impurities in the sealing groove 4 can also be cleaned in advance. When the sealing block 3 completely enters the sealing groove 4, it will fit tightly with the sealing groove 4. At the same time, the side wall of the sliding block 9 and the side wall of the sealing block 3 will fit tightly, thereby achieving a better sealing effect and thus a better protection effect.

[0033] When the sealing block 3 enters the sealing groove 4, it will enter the through groove 5 together with the clearing rod 14 and the scraper 15, and use the clearing rod 14 to clear the through groove 5. At the same time, the scraper 15 on the surface of the clearing rod 14 is rotationally connected by a torsion spring, so one end of the scraper 15 is tightly fitted with the inner wall of the through groove 5. As the clearing rod 14 continues to move downward, the scraper 15 will also play a role in assisting in cleaning the inner wall of the through groove 5, thereby effectively reducing the dust and impurities remaining inside the through groove 5 and preventing the through groove 5 from being blocked.
