Description

Technical Field

[0001] This invention relates to the field of high-pressure box cover manufacturing technology, specifically a forming mold for processing high-pressure box covers. Background Technology

[0002] High-pressure tank covers are typically used to seal and protect the media inside high-pressure vessels, thereby preventing the leakage of high-pressure gases or liquids and reducing potential risks. Therefore, robustness is paramount for high-pressure tank covers to withstand the high-pressure environment inside the vessel. Currently, high-pressure tank covers are usually manufactured using a casting process, where molten metal is poured into a mold and allowed to cool and solidify to form the cover.

[0003] In the prior art, a production mold for an automotive gearbox cover, disclosed in CN210172535U, includes a cooling box, a bottom mold, a top mold, and a pressure cap. The cooling box has a supporting base plate at its bottom, on which the bottom mold and top mold are mounted. A pressure cap is located at the top of the cooling box, tightly abutting the upper surface of the top mold. Cooling grooves in a U-shape are formed inside the sidewalls of the cooling box. By placing the bottom mold and top mold within the cooling box, and with the pressure cap connected to the top of the cooling box pressing them together, casting and cooling are integrated, improving production efficiency. When the top plate is lifted upwards using existing technologies such as hydraulic cylinders, the top plate lifts the supporting base plate via a push rod, causing the bottom mold and top mold placed above the supporting base plate to be ejected from the cooling box, facilitating demolding.

[0004] However, existing technologies still have significant drawbacks. For example, during the process of molten metal entering the mold and cooling and forming, air bubbles may be generated due to various reasons (such as excessively fast or slow filling speed, lack of venting channels in the mold, wear and corrosion on the inner surface of the mold, etc.). The aforementioned technologies do not have an exhaust mechanism to remove the generated air bubbles, which will reduce the quality of the high-pressure box cover and adversely affect its robustness. Furthermore, the aforementioned technologies use cooling water to cool and solidify the molten metal in the mold, but a small amount of cooling water will evaporate when passing through the overheated mold and scale will form in the cooling water flow channels. Over time, the scale will block the cooling water flow channels, which will adversely affect the cooling water flow and the cooling of the mold. Summary of the Invention

[0005] The purpose of this invention is to provide a forming mold for processing high-pressure box covers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

An exhaust pipe communicating with the high-pressure box cover forming cavity is installed on the upper end face of the upper mold. The lower mold is connected to an elastic support block to support its stability and an electromagnet that is intermittently energized to magnetically push the lower mold to slide up or down.

[0008] Both the upper and lower molds are provided with through cooling channels. After the upper and lower molds are aligned and locked, the lower end of the cooling channel of the upper mold and the upper end of the cooling channel of the lower mold are connected to form a cooling channel group. The two ends of the cooling channel group are respectively connected to the water supply end and the water return end of the external circulating cooling water circuit.

The lower end of the fixing rod is fixedly connected to the upper end face of the fixed base plate, and the upper end of the fixing rod passes upward through the hollow space of the elastic support block, the through hole of the fixed mounting plate, the cooling channel of the lower mold, and extends into the cooling channel of the upper mold.

There are two hollow elastic support blocks that are respectively sleeved on the outside of the two fixing rods, and the electromagnet and the iron plate are centrally located between the two elastic support blocks.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-5 The present invention provides a technical solution:

[0027] Example 1:

[0028] A forming mold for processing a high-pressure box cover includes an upper mold 1 with an inlet pipe 3 and a lower mold 2 located below the upper mold 1. Both the lower end face of the upper mold 1 and the upper end face of the lower mold 2 have mold grooves for manufacturing a high-pressure cover. The inlet pipe 3 is fixedly connected to the upper end of the upper mold 1, and the upper mold 1 has an inlet groove connecting the lower end of the inlet pipe 3 to the top wall of the mold groove inside the upper mold 1, allowing molten metal to enter the mold groove through the inlet pipe 3. The upper mold 1 and the lower mold 2 are aligned and locked together by a detachable connecting mechanism, so that the mold grooves of the upper mold 1 and the lower mold 2 form a high-pressure box cover. The upper mold 1 has an exhaust pipe 6 installed on its upper end face, which communicates with the high-pressure box cover molding cavity. Specifically, the exhaust pipe 6 is fixedly installed on the upper end face of the upper mold 1 and extends upward. The upper mold 1 has an exhaust groove that connects the lower end of the exhaust pipe 6 to the top wall of the mold groove inside the upper mold 1. This allows air in the high-pressure box cover molding cavity to be discharged through the exhaust pipe 6, avoiding the problem of air bubbles being generated due to gas remaining in the high-pressure box cover molding cavity. The lower mold 2 is connected to an elastic support block 4 that supports its stability, and an electromagnet 5 that is intermittently energized to magnetically push the lower mold 2 to slide upward or downward.

[0029] When manufacturing the high-pressure box cover, the upper mold 1 and the lower mold 2 are first aligned and locked by a detachable connecting mechanism, so that the mold grooves of the upper mold 1 and the lower mold 2 form the high-pressure box cover forming cavity. Then, molten metal is injected into the high-pressure box cover forming cavity through the liquid inlet pipe 3. During this process, the electromagnet 5 is intermittently energized, so that the electromagnet 5 is intermittently magnetic. When the electromagnet 5 is magnetic, the electromagnet 5 pushes the lower mold 2 and drives the upper mold 1 to slide up or down together. The elastic support block 4 undergoes elastic deformation. When the electromagnet 5 loses its magnetism, the lower mold 2 and the upper mold 1 slide back to their original positions under the elastic action of the elastic support block 4. By intermittently energizing the electromagnet 5, the upper mold 1 and the lower mold 2 vibrate up and down together, so that the molten metal in the high-pressure box cover forming cavity also vibrates up and down. During the up and down vibration, the molten metal discharges the internal gas, avoiding the problem of residual air bubbles in the molten metal during the subsequent cooling and shaping process, which would affect the quality of the final product. The gas discharged from the molten metal is discharged from the high-pressure box cover forming cavity through the exhaust pipe 6 and discharged into the external environment.

[0030] In one embodiment, a fixed base plate 10 is fixedly installed below the lower mold 2. Several support legs 13 for fixing are fixedly connected to the lower end face of the fixed base plate 10. There can be three or four support legs 13. The fixed base plate 10 is kept fixed by the support legs 13. A fixed mounting plate 11 is installed above the fixed base plate 10, and the fixed mounting plate 11 is detachably fixedly connected to the lower end face of the lower mold 2. The upper and lower ends of the elastic support block 4 are fixedly connected to the lower end face of the fixed mounting plate 11 and the upper end face of the fixed base plate 10, respectively. An electromagnet 5 is fixedly installed on the upper end face of the fixed base plate 10, and an iron magnet attracted to the electromagnet 5 is fixedly installed on the lower end face of the fixed mounting plate 11. When the electromagnet 5 is de-energized, the fixed mounting plate 11 remains stable under the support of the elastic support block 4, thereby making the lower mold 2 and upper mold 1 located on the fixed mounting plate 11 also stable. When the electromagnet 5 is energized, the iron plate 12 drives the fixed mounting plate 11 to slide downward under the magnetic attraction of the electromagnet 5, thereby making the locked lower mold 2 and upper mold 1 slide downward as well, and the elastic support block 4 is compressed. When the electromagnet 5 is de-energized, the fixed mounting plate 11 drives the lower mold 2 and upper mold 1 to slide upward under the elastic push of the elastic support block 4, thereby making the upper mold 1 and lower mold 2 vibrate up and down together by controlling the electromagnet 5 to be intermittently energized.

[0031] The lower mold 2 and the fixed mounting plate 11 are connected as follows: the lower mold 2 is fixedly connected to the first ear plate 14, and the first fixing bolt 15 passes through the first ear plate 14 and the fixed mounting plate 11 and is fixed by the first fixing nut 16. Through the cooperation of the first ear plate 14, the first fixing bolt 15 and the first fixing nut 16, the lower mold 2 can be detachably installed on the upper surface of the fixed mounting plate 11, which facilitates the subsequent removal of the lower mold 2 from the fixed mounting plate 11 for cleaning. An elastic washer is also provided between the end of the first fixing bolt 15 and the first ear plate 14. The elastic washer protects the end of the first fixing bolt 15.

[0032] The detachable connection mechanism includes second ear plates 17 fixedly connected to the side walls of the upper mold 1 and the lower mold 2. The second fixing bolts 18 pass through the second ear plates 17 on the upper mold 1 and the lower mold 2 and are fixed by the second fixing nuts 19. The cooperation of the second ear plates 17, the second fixing bolts 18 and the second fixing nuts 19 makes the lower mold 2 and the upper mold 1 detachably connected. When it is necessary to separate the molds, the second fixing nuts 19 are unscrewed and the second fixing bolts 18 are removed, so that the upper mold 1 and the lower mold 2 can be separated from each other. When it is necessary to close the molds, the upper mold 1 and the lower mold 2 are aligned so that the mold grooves of the two form a high-pressure box cover forming cavity. Then, the second fixing bolts 18 are passed through the second ear plates 17 and the second fixing nuts 19 are tightened to lock and fix the upper mold 1 and the lower mold 2. An elastic washer is also provided between the end of the second fixing bolt 18 and the second ear plate 17 near it. The elastic washer protects the end of the second fixing bolt 18.

[0033] Furthermore, a pressure strain ring 20 is provided between the end of the second fixing bolt 18 and the second ear plate 17 near it, and the shaft of the second fixing bolt 18 passes through the pressure strain ring 20. A signal transmitting antenna is provided inside the pressure strain ring 20 to send a signal to the intermittent timing switch of the electromagnet 5 under external pressure, causing the electromagnet 5 to intermittently operate. After the upper mold 1 and lower mold 2 are locked and fixed, the pressure strain ring 20 receives pressure from the end of the second fixing bolt 18 and sends a signal to the intermittent timing switch, causing the electromagnet 5 to intermittently operate, thereby causing the locked upper mold 1 and lower mold 2 to... The lower mold 2 vibrates up and down, and then injects molten metal into the high-pressure box cover forming cavity through the liquid inlet pipe 3. There is no need for the operator to manually start the electromagnet 5, which avoids the problem of the operator getting close to the mold during the liquid injection process and causing danger. After the liquid injection is completed, the operator can manually control the electromagnet 5 to stop working, so as to avoid the upper mold 1 and the lower mold 2 continuing to vibrate up and down and causing adverse effects on the subsequent cooling and shaping process. The pressure strain ring 20 can be a YSV-3-120-25-11L30M70 signal strain gauge, and the intermittent timer switch can be a JS14S timer relay.

[0034] Example 2:

[0035] Example 2 adds a cooling water cooling mechanism and a cooling water scale removal mechanism to Example 1. Specifically, both the upper mold 1 and the lower mold 2 have vertically connected cooling channels. After the upper mold 1 and lower mold 2 are aligned and locked, the lower end of the cooling channel of the upper mold 1 and the upper end of the cooling channel of the lower mold 2 are connected to form a cooling channel group. The two ends of the cooling channel group are respectively connected to the supply and return ends of an external circulating cooling water circuit. After the molten metal is injected into the high-pressure tank cover forming cavity, the supply end of the external circulating cooling water circuit sends cooling water to one end of the cooling channel group. The cooling water cools... The cooling water flows through the cooling channel group to absorb the heat from the upper mold 1 and the lower mold 2 and cool them, thereby cooling the molten metal in the high-pressure box cover forming cavity, accelerating the cooling and shaping of the high-pressure box cover. The cooling water that has absorbed heat flows out from the other end of the cooling channel group and enters the return end of the external circulating cooling water circuit, so that the cooling water that has absorbed heat flows back to the external circulating cooling water circuit for recooling. The recooled cooling water then enters the cooling channel group again through the water supply end. The external circulating cooling water circuit includes water supply pipes, circulating pumps and refrigeration components, which will not be described in detail here.

[0036] A fixed rod 7 is inserted into the cooling channel assembly. The rod 7 extends into the cooling channel assembly and has spiral blades that slide against the inner wall of the cooling channel assembly. During the up-and-down vibration of the upper mold 1 and the lower mold 2, the fixed rod 7 remains stationary, allowing the inner wall of the cooling channel assembly and the spiral blades on the fixed rod 7 to slide and rub against each other. The outer edge of the spiral blades scrapes off the scale generated on the inner wall of the cooling channel assembly due to the previous flow of cooling water, thus preventing scale from growing in the cooling channel assembly and blocking the flow of cooling water. When cooling water is supplied to cool the upper mold 1 and the lower mold 2, the cooling water flows spirally along the spiral blades on the fixed rod 7, extending the residence time of the cooling water in the cooling channel assembly. This allows the cooling water to fully absorb the heat of the upper mold 1 and the lower mold 2, thereby improving the utilization efficiency of the cooling water.

[0037] In one embodiment, the elastic support block 4 is a hollow elastic sleeve, and the fixed mounting plate 11 has a through hole that connects the hollow space of the elastic support block 4 and the lower end of the cooling channel of the lower mold 2. The lower end of the fixing rod 7 is fixedly connected to the upper surface of the fixed base plate 10, and the upper end of the fixing rod 7 passes upward through the hollow space of the elastic support block 4, the through hole of the fixed mounting plate 11, the cooling channel of the lower mold 2 and extends into the cooling channel of the upper mold 1. Through the cooperation of the fixing rod 7 with spiral blades and the cooling channel, the up-and-down vibration process of the upper mold 1 and the lower mold 2 is guided and limited, improving the stability of the up-and-down vibration process of the upper mold 1 and the lower mold 2. The fixing rod 7 is set to provide axial support for the elastic support block 4, avoiding the problem of excessive bending of the elastic support block 4 during compression deformation.

[0038] The upper end of the cooling channel of the upper mold 1 is connected to the return end of the external circulating cooling water circuit through the cooling water drain pipe 8. The cooling water drain pipe 8 can be a flexible hose or a telescopic pipe to adapt to the up and down vibration of the upper mold 1. The lower end of the fixed base plate 10 is fixedly installed with a cooling water inlet pipe 9, and the end of the cooling water inlet pipe 9 away from the fixed base plate 10 is connected to the water supply end of the external circulating cooling water circuit. The fixed base plate 10 is provided with a connecting groove that connects the cooling water inlet pipe 9 and the hollow space of the elastic support block 4. This allows the cooling water of the external circulating cooling water circuit to enter the cooling channel group through the cooling water inlet pipe 9, the connecting groove of the fixed base plate 10, the hollow space of the elastic support block 4, and the through hole of the fixed mounting plate 11. The cooling water in the cooling channel group after heat exchange flows back to the external circulating cooling water circuit through the cooling water drain pipe 8.

[0039] Furthermore, both the upper mold 1 and the lower mold 2 have two symmetrical cooling channels, and there are two fixing rods 7 inserted upward into the two sets of cooling channels respectively. There are also two hollow elastic support blocks 4, which are respectively sleeved on the outside of the two fixing rods 7. The electromagnet 5 and the iron plate 12 are centrally located between the two elastic support blocks 4. By setting up two sets of cooling channels, the cooling efficiency of the upper mold 1 and the lower mold 2 is improved. By setting up two sets of elastic support blocks 4 and fixing rods 7, the stability of the upper mold 1 and the lower mold 2 during the up and down vibration process is improved.

[0040] Working principle: When manufacturing the high-pressure box cover, the upper mold 1 and the lower mold 2 are first aligned and locked by a detachable connecting mechanism to form the high-pressure box cover forming cavity. Then, molten metal is injected into the high-pressure box cover forming cavity through the liquid inlet pipe 3. During this process, the electromagnet 5 is intermittently energized, so that the electromagnet 5 intermittently becomes magnetic, thereby causing the upper mold 1 and the lower mold 2 to vibrate up and down together. The molten metal in the high-pressure box cover forming cavity also vibrates up and down and discharges the residual gas inside. The gas discharged from the molten metal is discharged to the outside through the exhaust pipe 6.

[0041] During the up-and-down vibration of the upper mold 1 and the lower mold 2, the fixing rod 7 remains fixed, causing the inner wall of the cooling channel assembly and the spiral blades on the fixing rod 7 to slide and rub against each other. The outer edge of the spiral blades scrapes off the scale generated on the inner wall of the cooling channel assembly due to the previous flow of cooling water, thus preventing the scale from growing in the cooling channel assembly and blocking the flow of cooling water.

[0042] After the liquid injection is completed, the water supply end of the external circulating cooling water circuit sends cooling water to one end of the cooling channel group. The cooling water flows in the cooling channel group to absorb the heat of the upper mold 1 and the lower mold 2 and cool them. This, in turn, cools the molten metal in the high-pressure box cover forming cavity. The cooling water that has absorbed heat flows out from the other end of the cooling channel group and enters the return end of the external circulating cooling water circuit. This allows the cooling water that has absorbed heat to flow back into the external circulating cooling water circuit for recooling. The recooled cooling water then enters the cooling channel group again through the water supply end. The cooling water flows spirally along the spiral blades on the fixed rod 7 in the cooling channel group, extending the residence time of the cooling water in the cooling channel group. This allows the cooling water to fully absorb the heat of the upper mold 1 and the lower mold 2, improving the utilization efficiency of the cooling water.
