Description

Technical Field

[0001] The utility model relates to the technical field of moulds, in particular to a high-pressure casting mould capable of quickly exhausting air. Background Technique

[0002] In injection moulding, raw materials are injected into a mould, and then the solidified material is made to form a specific shape by means of blowing and mould clamping. If there is air in the mould, the product is liable to be scorched, reducing the product quality. Therefore, it is necessary to exhaust the air inside the mould during the operation of the mould.

[0003] The existing methods for exhausting air from moulds usually adopt the method of opening exhaust grooves or exhausting air through exhaust needles. Such operation methods have high requirements for the positions of the exhaust grooves and exhaust needles. Therefore, a large amount of time is required for the production of moulds to experiment with the air exhaust effect of the moulds, thus reducing the practicability and production efficiency of the existing moulds. At the same time, the application of exhaust grooves and exhaust needles still cannot effectively solve the problem of air exhaust from the moulds, resulting in the situation that some products are scorched or even have flash and grinding marks, reducing the quality of the products produced by the existing moulds. For this reason, we propose a high-pressure casting mould capable of quickly exhausting air. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 - 8A high-pressure casting mold capable of rapid exhaust comprises an upper mold 1, a lower mold 2 is arranged below the upper mold 1, an extrusion rod 4 is fixedly mounted on the bottom of the upper mold 1, an exhaust groove 3 is provided at the bottom of the inner wall of the lower mold 2, a circular groove 6 is provided on the inner wall of the exhaust groove 3, a circular groove 7 is provided on the inner wall of the circular groove 6, strip grooves 8 are provided on both sides of the lower mold 2, a movable groove 14 is provided on the inner wall of the strip groove 8, a straight rod 9 is fixedly mounted on the inner wall of the strip groove 8, a return spring 10 is sleeved on the outer wall of the straight rod 9, a slide bar 11 is abutted on the top of the return spring 10, an installation groove 18 is provided in the middle of the slide bar 11, a pressure spring 19 is sleeved on the inner wall of the installation groove 18, a push rod 13 is abutted on the outer wall of the pressure spring 19, and a push rod 13 is abutted on the outer wall of the installation groove 18. An air outlet hole 12 is provided on the inner wall, an air outlet groove 15 and a fixing hole 17 are respectively provided on the inner wall of the strip groove 8, an ultrafiltration membrane 16 is fixedly installed on the inner wall of the air outlet groove 15, and a sleeve 5 is fixedly installed on the inner wall of the fixing hole 17. An air outlet pipe 20 is passed through the end of the sleeve 5 close to the lower mold 2, an electromagnetic valve 21 is provided on the inner wall of the air outlet pipe 20, an ultrafiltration membrane 22 is provided below the electromagnetic valve 21, an electrode sheet 23 is fixedly installed on the outer wall of the ultrafiltration membrane 22, a controller 24 is fixedly installed on the end of the sleeve 5 away from the lower mold 2, an electromagnet 25 is fixedly installed on the inner wall of the sleeve 5, a reset spring 26 is sleeved on the inner wall of the sleeve 5, a permanent magnet 27 is abutted on the outer wall of the reset spring 26, and a push rod 28 is fixedly installed on the outer wall of the permanent magnet 27.

[0028] In the above structure, by setting the upper mold 1, the lower mold 2, the exhaust groove 3, the extrusion rod 4, the sleeve 5, the push rod 13, the exhaust groove 15, the electromagnetic valve 1 21, the ultrafiltration membrane 2 22, the electromagnet 25, and the push rod 28 structure, during the operation of the casting mold, the user can combine the upper mold 1 and the lower mold 2 to make the extrusion rod 4 squeeze the slide 11, so that the slide 11 moves downward and the push rod 13 moves to the position corresponding to the push rod 28, so that the push rod 28 moves toward the controller 24, and the push rod 1 The distance between 13 and the air outlet 12 is such that after injection molding in the mold, the air inside the lower mold 2 can enter the sleeve 5 through the air outlet 12, and at the same time, the change in the air pressure inside the sleeve 5 is used to make the two electrode sheets 23 overlap, and the controller 24 is used to automatically open the solenoid valve 1 21, and the exhaust groove 3, the circular groove 1 6, and the circular groove 2 7 can also discharge the air by opening the solenoid valve 2, thereby improving the exhaust efficiency of the casting mold for the air in the mold, avoiding the product from being burned during the casting process, and improving the casting quality of the product by the casting mold.

[0029] In a preferred embodiment: a limiting groove is formed in the inner wall of the mounting groove 18. One end of the first push rod 13 located on the inner wall of the mounting groove 18 is fixedly assembled with a limiting ring. A limiting block is fixedly assembled on the outer wall of the limiting ring, and the outer wall of the limiting block is slidably connected to the inner wall of the limiting groove. A 1-cm gap is provided between the outer walls of the first push rod 13 and the limiting ring and the inner wall of the air outlet hole 12 and the mounting groove 18 respectively.

[0030] In the above structure, through the arranged limiting groove, limiting block and limiting ring structures, the cooperation of the limiting groove, limiting ring and limiting block can prevent the first push rod 13 from tilting or even shifting in position when it is in a static state. At the same time, when the first push rod 13 and the limiting ring move, they move horizontally, thus ensuring that the first push rod 13 can stably push the second push rod 28 to move, and further improving the stability of the first push rod 13.

[0031] In a preferred embodiment: the side of the slide bar 11 away from the first push rod 13 is closely attached to the inner wall of the strip-shaped groove 8, and a 1-cm gap is provided between the side of the slide bar 11 close to the first push rod 13 and the inner wall of the movable groove 14. The inside of the sleeve 5 is respectively communicated with the inside of the upper mold 1 through the first push rod 13 and the air outlet groove 15.

[0032] In the above structure, the distance between the slide bar 11 and the movable groove 14 can ensure that after the slide bar 11 moves downward, the air outlet groove 15 is exposed and the ultrafiltration membrane I 16 is used to block the material, achieving the effect of gas-liquid separation, ensuring that the injection molding material cannot enter the strip-shaped groove 8 through the air outlet groove 15, thereby ensuring the integrity and beauty of the product. And the gas can enter the sleeve 5 by squeezing the air through the gap and the filling of the material into the inside of the lower mold 2, thus ensuring that the casting mold can quickly discharge the air.

[0033] In a preferred embodiment: the number of the ultrafiltration membranes II 22 is two, and when the inside of the sleeve 5 is communicated with the inside of the upper mold 1, the outer walls of the two electrode plates 23 are overlapped. The controller 24 is electrically connected to the electrode plates 23, the solenoid valve I 21 and the electromagnet 25 respectively.

[0034] In the above structure, through the set structure of the controller 24, when air enters the sleeve 5, the air pressure inside the sleeve 5 will increase, causing the shape of the ultrafiltration membrane II 22 to change, so that the two electrode plates 23 come into contact. After contact, the controller 24 controls the electromagnet 25 to change the magnetic pole to adsorb the permanent magnet 27, ensuring that the inside of the sleeve 5 is always communicated with the inside of the slide bar 11, so that air can be discharged to the outside of the sleeve 5. During the discharge process, the air volume decreases, making the air pressure inside the sleeve 5 less than the external air pressure. Therefore, the ultrafiltration membrane II 22 returns to its original state, the two electrode plates 23 separate, causing the controller 24 to control the electromagnet 25 to change the magnetic pole again, and at the same time controlling the solenoid valve I 21 to close, thereby ensuring that external air cannot flow back into the mold during the operation of the casting mold, and ensuring that the product will not be affected by the backflow air during the casting process.

[0035] In a preferred embodiment: when the two electrode plates 23 overlap, the electromagnet 25 and the permanent magnet 27 attract each other with opposite polarities, and when the two electrode plates 23 separate, the electromagnet 25 and the permanent magnet 27 repel each other with the same polarities.

[0036] In the above structure, through the set structure of the permanent magnet 27 and the electromagnet 25, when the permanent magnet 27 and the electromagnet 25 attract each other with opposite polarities, it can assist the push rod I 13 to quickly fix the push rod II 28, so as to ensure that air can be discharged to the outside of the sleeve 5 without being affected by the push rod II 28. When they repel each other with the same polarities, it can make the push rod I 13 completely separate from the sleeve 5, avoiding the situation that the upper mold 1 cannot be lifted normally due to the limiting effect of the push rod I 13 during the lifting process, thereby improving the intelligence and automation of the casting mold.

[0037] In a preferred embodiment: the number of sleeves 5 is several, and several sleeves 5 are evenly distributed along the outer wall of the lower mold 2.

[0038] In the above structure, through the set structure of several sleeves 5, the mold can discharge the air inside the lower mold 2 through the sleeves 5 at different positions, so as to ensure that the product will not be scorched or have flash during the operation of the mold, thereby improving the product quality of the casting mold.

[0039] In a preferred embodiment: the number of the first circular grooves 6 is two, and the second circular groove 7 is located at the center points of the two first circular grooves 6, and a solenoid valve II is provided on the inner wall of the second circular groove 7.

[0040] In the above structure, through the two structures of the first circular groove 6 and the second circular groove 7, by using the characteristic that the diameters at both ends between the two first circular grooves 6 and the second circular groove 7 are large while the diameter in the middle is small, a Venturi effect is formed. After the air enters the first circular groove 6, due to the smaller cross-sectional diameter of the second circular groove 7, the air can quickly pass through the second circular groove 7 and be discharged to the outside of the lower mold 2 through another first circular groove 6, further improving the exhaust efficiency of the casting mold.

[0041] In a preferred embodiment: The outer wall of the first push rod 13 is slidably connected to the inner wall of the movable groove 14, and the first push rod 13 is made of galvanized iron metal.

[0042] In the above structure, the galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the wear degree of the first push rod 13 during operation. And the galvanized iron metal also has the characteristic of hardness, which can ensure that the driving force of the first push rod 13 on the second push rod 28 will not affect the first push rod 13, thus extending the service life of the first push rod 13 and ensuring the normal operation of the mold. At the same time, the galvanized iron metal also has the characteristic of low cost, thereby reducing the production cost and production requirements of the mold.

[0043] In a preferred embodiment: A hydraulic cylinder and a feeding pipe are respectively provided at the top of the upper mold 1.

[0044] In the above structure, through the structures of the hydraulic cylinder and the feeding pipe, the hydraulic cylinder can be used to perform the mold clamping operation on the upper mold 1 and the lower mold 2, thereby ensuring the shaping effect of the mold on the product.

[0045] Working principle: First, after the user assembles the mold, injection molding operations can be carried out through the injection pipe. Subsequently, during the mold clamping process, the extrusion rod 4 will move downward with the upper mold 1 and push the slide bar 11 to move. At this time, the first push rod 13 will slide along the inner wall of the movable groove 14 until it coincides with the position of the second push rod 28, so that the first push rod 13 pushes the second push rod 28 towards the controller 24. As the injection molding operation continues, the air inside the lower mold 2 is squeezed and flows, and then the air enters the first circular groove 6 and the air outlet 12 respectively. When passing through the second circular groove 7, the Venturi effect is generated due to the smaller diameter of the second circular groove 7, causing the air to be quickly discharged. The air in the air outlet 12 will enter the sleeve 5, increasing the pressure inside the sleeve 5, so that the two electrode plates 23 are in contact. At this time, under the control of the controller 24, the first solenoid valve 21 will open, and then the air is discharged, achieving the effect of rapid exhaust. After the air is discharged, the pressure inside the sleeve 5 is less than the external pressure, so the second ultrafiltration membrane 22 will return to its original state and the two electrode plates 23 will separate. At this time, the controller 24 will control the electromagnet 25 to change the magnetic pole and let the second push rod 28 move towards the lower mold 2, thus pushing the first push rod 13 away from the sleeve 5, ensuring that the extrusion rod 4 will not be blocked when lifting, and thus improving the automation and intelligence of the mold.
