[0032] In the related art, during the vacuum casting process, an epoxy mixture is injected into the mold cavity of an injection mold through a nozzle of a feeding mechanism to form a mold. When injecting the material, there is a situation where the material leaks from the feeding mechanism, which needs to be dealt with in a timely manner. If not dealt with, it will cause leakage pollution and component failures such as the feeding device, and even affect the sealing performance of the entire injection mold, resulting in production defects in the product and causing losses of manpower and material resources. However, dealing with leakage is time-consuming and laborious and affects production efficiency.
[0033] As Figure 1 , Figure 2 and Figure 3 shown, to solve the above technical problems, an embodiment of the present application provides a vacuum feeding box, which includes a vacuum box 100, a guiding tray 400, and a receiving tray 300. The middle of the guiding tray 400 has a mounting hole 440, and a nozzle 500 is passed through the mounting hole 440. Both the guiding tray 400 and the receiving tray 300 are arranged in the vacuum box 100. A sealing is provided between the mounting hole 440 and the nozzle 500, and the guiding tray 400 has a discharge port 420, and the falling position of the discharge port 420 is located within the receiving tray 300.
[0034] In these embodiments, the middle of the guiding tray 400 has a mounting hole 440. The guiding tray 400 is used to be mounted on an injection mold, and the nozzle 500 of the injection mold is passed through the mounting hole 440, and the mounting hole 440 and the nozzle 500 are in interference fit to achieve a sealing setting therebetween, thereby facilitating controlling the gap between the mounting hole 440 and the nozzle 500 to reduce the amount of material flowing out from the gap. Of course, in other embodiments, other sealing methods can also be used. As for the connection method between the guiding tray 400 and the injection mold, for example, the main feeding mechanism is provided with a nozzle 500, and the guiding tray 400 and the receiving tray 300 are placed above the upper end of the bottom of the vacuum box 100 and below the injection mold within the vacuum box 100, so as to support the guiding tray 400 through the vacuum box 100 and cooperate to insert the nozzle 500 into the mounting hole 440 to achieve the positioning of the guiding tray 400. Of course, in other embodiments, the guiding tray 400 and the vacuum can also be set to be detachably connected, such as bolt connection, snap connection, etc. It should be noted that the height difference between the guiding tray 400 and the receiving tray 300 needs to be ensured. For example, the guiding tray 400 can be raised by adding a spacer block or other means.
[0035] Among them, a discharge port 420 is provided on the material guiding plate 400 for guiding the leaked material to the material receiving plate 300. The main function of the material guiding plate 400 is to guide the material leaked from the injection nozzle 500 to the material receiving plate 300, preventing the material from directly falling on the equipment or the ground. The material receiving plate 300 is arranged below the material guiding plate 400 for receiving the leaked material flowing out from the discharge port 420. It should be noted that the discharge port 420 forms a material dropping position in the material receiving plate 300, that is, to ensure that the material falls into the material receiving plate 300 after flowing out from the discharge port 420 to avoid spilling. The main function of the material receiving plate 300 is to collect the leaked material, prevent the leaked material from polluting the environment and the equipment, and at the same time facilitate subsequent cleaning and recycling.
[0036] During the vacuum casting process, the epoxy mixed material is injected into the mold cavity through the pouring port 200 of the injection mold by the injection nozzle 500 of the injection mechanism. When the material leaks, the leaked material will first flow into the material guiding plate 400 and flow out through the discharge port 420. After the leaked material flows out from the discharge port 420, it falls into the material receiving plate 300 below.
[0037] Obviously, through the design of the material guiding plate 400 and the material receiving plate 300, the leaked material can be collected in time, reducing material waste and spillage pollution, and there is no need for timely cleaning, preventing the leaked material from polluting the environment and the equipment, improving the cleanliness of the production environment, and achieving the purpose of saving time and effort. Moreover, the time and labor for dealing with the leaked material are reduced, and the production efficiency is improved. Among them, the design of the material receiving plate 300 and the material guiding plate 400 is convenient for disassembly and cleaning, simplifying the maintenance work. It should be noted that since there is no direct fixed connection between the material receiving plate 300 and the material guiding plate 400, that is to say, the two are easy to separate. After the material receiving plate 300 is filled with the leaked material, it can be replaced in time without affecting continuous production. And when the production is over, both the material receiving plate 300 and the material guiding plate 400 can be removed for cleaning.
[0038] Of course, the number of the material receiving plates 300 is not specifically limited. Exemplarily, in this embodiment, the number of the material receiving plates 300 is two; in other embodiments, the number of the material receiving plates 300 can also be set to one, three, four, five, six, seven, etc., and the specific setting can be determined according to the space and actual needs.
[0039] Such as Figure 3 and Figure 4 As shown, in some embodiments, the bottom of the material guiding plate 400 has a recessed area 410, and the discharge port 420 is located in the recessed area 410.
[0040] In these embodiments, the bottom of the material guiding plate 400 is designed with a recessed area 410 for collecting the leaked material. The discharge port 420 is located in the recessed area 410, and the discharge port 420 is used to guide the collected leaked material to the material receiving plate 300.
[0041] When the material leaks, the leaked material will first flow into the recessed area 410 of the material guide plate 400. The leaked material is converged in the recessed area 410 and flows out through the discharge port 420. After the leaked material flows out from the discharge port 420, it falls into the receiving tray 300 below. That is to say, by setting the recessed area 410 at the bottom of the material guide plate 400, the leaked material can be collected more effectively, preventing the leaked material from scattering everywhere. Obviously, the design of the recessed area 410 can ensure that the leaked material is concentrated for better discharge, reducing the residue amount in the material guide plate 400.
[0042] Exemplarily, in the present embodiment, the discharge port 420 is arranged at the lowest point of the recessed area 410. Such an arrangement is more conducive to the rapid discharge of the material and reducing the residue amount of the material.
[0043] In addition, the size of the discharge port 420 should be appropriate, which can not only ensure the smooth outflow of the leaked material but also not be too large to cause the leaked material to splash out. Exemplarily, the discharge port 420 can be designed into a circular shape, a rectangular shape or other shapes, specifically depending on the actual needs.
[0044] Exemplarily, the recessed area 410 can be designed into a conical shape, a rectangular shape or other shapes, specifically depending on the actual needs.
[0045] As Figure 4 shown, in some embodiments, the discharge port 420 is arranged on the side wall of the material guide plate 400, and the part of the bottom of the material guide plate 400 located in the recessed area 410 gradually decreases in the direction close to the discharge port 420.
[0046] In these embodiments, the discharge port 420 is arranged on the side wall of the material guide plate 400 instead of the center of the bottom. The part of the bottom of the material guide plate 400 located in the recessed area 410 gradually decreases in the direction close to the discharge port 420, forming an inclined surface to have a guiding effect. When the material leaks, the leaked material will first flow into the recessed area 410 of the material guide plate 400 and gradually flow towards the discharge port 420 through the inclined bottom design. After the leaked material flows out from the discharge port 420, it falls into the receiving tray 300 below.
[0047] It should be noted that the size of the discharge port 420 should be appropriate, which can not only ensure the smooth outflow of the leaked material but also not be too large to cause the leaked material to splash out. And, the bottom of the material guide plate 400 gradually decreases in the direction close to the discharge port 420, forming an inclined surface, and the angle should be appropriate to ensure the smooth inflow of the leaked material into the discharge port 420.
[0048] Exemplarily, the material guide plate 400 has four side walls, the discharge port 420 is arranged on one of the side walls, and the discharge port 420 can be arranged to cover the entire side wall where it is located. Equivalently, one of the side walls is cancelled to form the discharge port 420.
[0049] The structure of the material guiding plate 400 is further defined. The middle part of the material guiding plate 400 is set as a flat surface so as to stably fit the upper end of the injection mold, and the concave area 410 is arranged at the edge of the material guiding plate 400.
[0050] As Figure 3 shown, in some embodiments, the number of the material receiving trays 300 is two, and discharge ports 420 are respectively arranged on a pair of opposite side walls of the material guiding plate 400, and each discharge port 420 is correspondingly provided with a material receiving tray 300.
[0051] In these embodiments, this design further optimizes the collection and treatment process of the leaked material, enabling the leaked material to be collected more evenly, and improving the stability and reliability of the system. Obviously, by providing two material receiving trays 300, the leaked material can be collected more evenly, reducing the load on a single material receiving tray 300.
[0052] Moreover, the design of two material receiving trays 300 improves the stability of the system. Even if a problem occurs on one side, the other side can still continue to collect the leaked material.
[0053] Exemplarily, the material receiving tray 300 can be designed into a square, a circle or other shapes, specifically depending on the actual needs.
[0054] In some embodiments, the vacuum injection box further includes a support member. The support member is located inside the vacuum box 100, is arranged at the bottom of the vacuum box 100, has a sliding groove 600 which extends along a preset direction. The discharge port 420 is located outside the material receiving tray 300, the material receiving tray 300 is placed in the sliding groove 600, and the material receiving tray 300 can move along the sliding groove 600; wherein, there is at least one material receiving station on the moving path of the material receiving tray 300, the discharge port 420 is located directly above the material receiving station, and the preset direction is horizontally arranged.
[0055] In these embodiments, this design enables the material receiving tray 300 to move in the sliding groove 600, thereby realizing more flexible adjustment of the position of the material receiving tray 300, which is conducive to quickly aligning the material receiving tray 300 with the discharge port 420 for collecting and treating the leaked material. That is to say, after placing the material receiving tray 300 in the sliding groove 600, only need to push the material receiving tray 300 to move along the sliding groove 600 to adjust the position, that is, move the material receiving tray 300 to the material receiving station. It should be noted that by configuring the position of the discharge port 420, a material receiving station is formed below the discharge port 420, that is, when the material receiving tray 300 is at the material receiving station, it can ensure receiving the material discharged from the discharge port 420.
[0056] Among them, setting the sliding groove 600 horizontally means that it can ensure that the material receiving tray 300 placed in the sliding groove 600 can be in a horizontal state, and at this time, the material receiving tray 300 can hold more materials.
[0057] As Figure 3 shown, in some embodiments, the support member includes a bottom plate 610 and side plates 620. The side plates 620 are respectively arranged on both sides of the bottom plate 610. The side plates 620 and the bottom plate 610 both extend along a preset direction, and a chute 600 is formed between the side plates 620 and the bottom plate 610. Among them, in the preset direction, the length of the side plate 620 is L1, the length of the bottom plate 610 is L2, and the length of the receiving tray 300 is L3, and it satisfies: L1 < L3 < L2.
[0058] In these embodiments, this design enables at least one end of the receiving tray 300 to be located outside the chute 600, that is to say, it is convenient to take and place the receiving tray 300.
[0059] Exemplarily, in the horizontal direction away from the discharge port 420, the end of the bottom plate 610 away from the discharge port 420 among the end of the side plate 620 away from the discharge port 420 and the end of the bottom plate 610 away from the discharge port 420 is farther away from the discharge port 420. That is to say, after the receiving tray 300 is moved out of the chute 600, the bottom plate 610 can still carry the guiding tray 400, which is convenient for manual taking and placing.
[0060] Exemplarily, the bottom plate 610 is the bottom wall of the vacuum chamber 100, which can further simplify the structure. It only needs to install the side plates 620 on the bottom wall of the vacuum chamber 100. Of course, in other embodiments, the bottom plate 610 can also be separately arranged and fixed inside the vacuum chamber 100.
[0061] As Figure 4 shown, in some embodiments, the orientation of the discharge port 420 intersects with the bottom of the receiving tray 300, and the included angle between the orientation of the discharge port 420 and the bottom of the receiving tray 300 is α, and it satisfies: α < 90°.
[0062] In these embodiments, this design can reduce the impact force acting on the receiving tray 300 when the material is discharged from the discharge port 420 into the receiving tray 300, thereby reducing the splashing of the material.
[0063] Exemplarily, α is set to 30°. Of course, in other embodiments, α can also be set to 40°, 50°, 60°, 70°, etc.
[0064] As Figure 3 shown, in some embodiments, a card slot 611 is arranged at the receiving station. The card slot 611 can accommodate the bottom of the receiving tray 300. Among them, the guiding tray 400 and the injection nozzle 500 are in positioning cooperation, and the positioning cooperation can make the falling position of the discharge port 420 of the guiding tray 400 located at the receiving station.
[0065] In these embodiments, the card slot 611 is disposed within the sliding groove 600. That is to say, the receiving tray 300 can be pushed to move along the sliding groove 600, thereby facilitating the entry of the receiving tray 300 into the card slot 611 to achieve the limitation of the receiving tray 300. This can not only prevent the receiving tray 300 from shifting, but also achieve precise docking between the receiving tray 300 and the discharge port 420. Among them, the internal contour of the card slot 611 should be adapted to the external shape of the receiving tray 300. For example, if the receiving tray 300 is square, the card slot 611 should also be set to square.
[0066] In addition, for the positioning and cooperation between the material guiding tray 400 and the injection nozzle 500, it has the following functions: it can limit the installation position of the material guiding tray 400 to ensure that the discharge port 420 of the installed material guiding tray 400 is exactly aligned with the receiving tray 300, eliminating the need for repeated adjustment and reducing the risk of the material guiding tray 400 shifting.
[0067] Exemplarily, the injection nozzle 500 has a step, the bottom of the material guiding tray 400 abuts against the step, and a positioning portion is provided on the step. A positioning groove is provided at the bottom of the material guiding tray 400, and the positioning portion is used for inserting into the positioning groove to achieve the positioning and cooperation between the material guiding tray 400 and the injection nozzle 500. It is easy to understand that the positioning portion is set as a positioning pin, the positioning groove is a positioning hole, and both the positioning pin and the positioning hole extend in the same direction as the injection nozzle 500.
[0068] As Figure 3 and Figure 4 shown, in some embodiments, the middle of the material guiding tray 400 has a convex portion 430, the mounting hole 440 is disposed on the convex portion 430, the convex portion 430 is lower than the injection nozzle 500, a groove is provided on one of the inner wall of the mounting hole 440 and the outer wall of the injection nozzle 500, an elastic sealing ring is installed in the groove, and the other of the inner wall of the mounting hole 440 and the outer wall of the injection nozzle 500 abuts against the elastic sealing ring for sealing.
[0069] In these embodiments, the following situations exist:
[0070] 1) A groove is provided on the inner wall of the mounting hole 440, and an elastic sealing ring is installed in the groove, thereby sealing the gap between the mounting hole 440 and the injection nozzle 500 through the elastic sealing ring;
[0071] 2) A groove is provided on the outer wall of the injection nozzle 500, and an elastic sealing ring is installed in the groove, thereby sealing the gap between the mounting hole 440 and the injection nozzle 500 through the elastic sealing ring.
[0072] Obviously, with the above settings, not only can the sealing between the mounting hole 440 and the injection nozzle 500 be achieved, but also the disassembly and assembly of the material guiding tray 400 are facilitated, which is conducive to cleaning and installation.
[0073] As Figure 1As shown, in some embodiments, the present application further provides a feeding mechanism, and the feeding mechanism includes a vacuum feeding tank as described in any one of the above embodiments.
[0074] Since the above vacuum feeding tank has the above technical effects, the feeding mechanism including the vacuum feeding tank should have the same technical effects, which will not be elaborated here.
[0075] In all the examples shown and described here, any specific value should be construed as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values.
[0076] It should be noted that like reference numerals and letters denote like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0077] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
