Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a multifunctional sand mixer casting mold. Background Technology

[0002] Sand mixers are key equipment used in casting production for mixing sand materials. Their main function is to mix casting sand, binders and other auxiliary materials evenly to prepare molding sand and core sand that meet casting requirements. Because they can evenly distribute binders and auxiliary materials and effectively coat the surface of sand particles, they can ensure the quality of sand molds or sand cores.

[0003] Because of its high degree of automation, the sand mixer can quickly and in large quantities prepare sand, significantly improving casting production efficiency. The sand mixed by the sand mixer also has significantly improved strength and toughness, which is conducive to the manufacture of solid sand molds, reducing breakage during the casting process. It can also adapt to various types of sand and binders to meet the needs of different casting processes. Therefore, it is widely used in the casting industry. When the mixed sand needs to be made into objects of specific shapes, a multi-functional sand mixer casting mold is required.

[0004] The existing multi-functional sand mixer casting mold has the following shortcomings:

[0005] Currently, the casting molds of multi-functional sand mixers on the market are all made in one piece. When it is necessary to make models of various sizes, different molds need to be changed. Once the mold is formed, the size cannot be adjusted. As a result, when there is a slight difference in the size of the mold, a new mold still needs to be cast in order to standardize the production model, which causes waste and reduces production efficiency.

[0006] Therefore, we propose a multifunctional sand mixer casting mold to solve the problems mentioned above. Utility Model Content

[0007] This device allows for mold size changes without the need for mold replacement. The template slides inside the frame, which is fixed to the outside. A sliding push rod in the push rod hole inside the frame is fixed to the template, and its other end is connected to a push plate. The push plate has a fixed rotating wheel and a ring in its rotating hole. A threaded rod on the wheel is connected to a threaded hole in the frame. Rotating the wheel moves the threaded rod, which in turn moves the push plate, the sliding push rod, and the template inward. The template spacing can be adjusted to change the mold size, adapting to the production of different sized molds, improving efficiency, and reducing waste. For mold gaps caused by dry sand and large particles, a support spring and a funnel are installed at the top of the template. The funnel is connected to an inclined flow pipe to the four corners of the mold. The sand flows into the mold through the funnel, naturally filling the dead corners and reducing the possibility of gaps. Due to the characteristics of the spring, the funnel can be manually shaken to accelerate the sand flow rate, making the distribution more uniform and reducing mold defects, thus solving the problems mentioned in the background technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional sand mixer casting mold, comprising a frame, a plurality of templates slidably connected to the inner side of the frame, a plurality of sliding push rods fixedly connected to the outer side of the templates, a push plate fixedly connected to the outer side of the plurality of sliding push rods, a rotating hole provided on the inner side of the push plate, a rotating wheel rotatably connected to the inner side of the rotating hole, a rotating ring fixedly connected to the outer side of the rotating wheel, a threaded rod fixedly connected to the inner side of the rotating wheel, a plurality of fixed frames fixedly connected to the outer side of the frame, and a diversion mechanism provided on the top of the plurality of templates.

[0009] Preferably, it includes a support spring, which is fixedly connected to the top of the template, and the other end of the support spring is fixedly connected to a funnel, the bottom of which is connected to multiple diversion pipes.

[0010] Preferably, the inner sides of the upper and lower fixed frames are provided with a plurality of push rod holes, and the plurality of push rod holes are slidably connected to a plurality of sliding push rods.

[0011] Preferably, the inner side of the middle fixing frame is provided with multiple threaded holes, and the threaded holes are threadedly connected to the threaded rod.

[0012] Preferably, the inner side of the frame is provided with a plurality of vent holes, and the bottom of the frame is fitted with a vent plug plate, wherein the vent plug plate is fixed with vent plugs of the same number and size as the vent holes.

[0013] Preferably, two spring sliders are fixedly connected to the outer side of the vent plug, and a fixing hole is opened on the inner side of the vent plug. A fixing bolt is slidably connected inside the fixing hole, and the other end of the fixing bolt is fixedly connected to the fixing frame.

[0014] Preferably, a plurality of temperature sensors are fixedly connected to the inner side of the template, a signal transceiver is fixedly connected to the top of the template, and a plurality of indicator lights are fixedly connected to the top of the signal transceiver.

[0015] Preferably, the bottom of the frame is provided with a movable base, and the bottom of the movable base is fixedly connected with multiple casters.

[0016] Preferably, the rotating ring is rotatably connected inside the rotating hole, and the outer side of the rotating wheel is fitted with an anti-slip sleeve.

[0017] Preferably, the bottom of the support spring is fixed with a plug that facilitates loading and unloading, and the top of the template has a plug hole that is slightly larger than the size of the plug at the corresponding position.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, when the device is actually used and the mold size needs to be changed, there is no need to change the mold. This is because the template slides inside the frame, and a fixed frame is fixed outside the frame. There is a sliding push rod in the push rod hole inside the fixed frame and it is fixed to the template. The other end of the sliding push rod is connected to a push plate. There is a fixed rotating wheel and a rotating ring in the rotating hole inside the push plate. A threaded rod is fixed on the rotating wheel and connected to the threaded hole of the middle frame. Rotating the rotating wheel causes the threaded rod to rotate in the threaded hole. Because the rotating ring is limited, when the threaded rod moves inward, it drives the push plate inward. The push plate causes the sliding push rod to move inward along the push rod hole, and the template moves inward accordingly. By changing the spacing of the four templates, the mold size can be changed, realizing the production of different sized models, improving the mold utilization rate, reducing waste, and improving production efficiency.

[0020] 2. In this utility model, when the mixed sand is too dry and the particles are too large during actual operation, it is easy for voids to appear inside the mold due to the poor flowability of such sand. In the past, this situation required manual stirring with a stirring rod inside the mold, which greatly increased the workload. To address this, multiple support springs are installed at the top of the mold template, with a funnel fixed to the other end of each spring. The funnel is connected to a flow pipe that slopes outwards. After the mixed sand is discharged, it is poured into the funnel, and the sand flows along the flow pipes to the four bottom corners of the mold. This allows the sand to fall naturally and fully fill the dead corners of the mold, reducing the possibility of voids. When the flow rate of the sand in the funnel slows down, the funnel can be manually shaken to make the sand shake inside the funnel and increase the flow rate. At the same time, the shaking process also makes the sand distribution inside the mold more uniform, effectively reducing the occurrence of voids in the mold due to sand problems, which could ultimately lead to mold defects.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, as shown in the attached document Figure 1 , Figure 2 and Figure 3 As shown, a multifunctional sand mixer casting mold includes a frame 1. Multiple templates 4 are slidably connected to the inner side of the frame 1. Multiple sliding push rods 5 are fixedly connected to the outer side of the templates 4. Push plates 6 are fixedly connected to the outer side of the multiple sliding push rods 5. A rotating hole 22 is opened on the inner side of the push plate 6. A rotating wheel 7 is rotatably connected to the inner side of the rotating hole 22. A rotating ring 8 is fixedly connected to the outer side of the rotating wheel 7. A threaded rod 9 is fixedly connected to the inner side of the rotating wheel 7. Multiple fixing frames 3 are fixedly connected to the outer side of the frame 1. A diversion mechanism 2 is provided on the top of the multiple templates 4.

[0031] The effect achieved by the entire embodiment 1 is as follows: when the threaded rod 9 rotates and moves inward, its rotating ring 8 moves accordingly, and then the push plate 6 is driven to move inward through the limit. The push rod hole 11 allows the sliding push rod 5 to move inward stably. The template 4 is pushed inward by the sliding push rod 5. By adjusting the distance between the four templates 4, the overall size of the mold can be changed, thereby realizing the function of producing models of different sizes.

[0032] Example 2, as Figure 2 and Figure 4As shown, it includes a support spring 201, which is fixedly connected to the top of the template 4. The other end of the support spring 201 is fixedly connected to a funnel 202, and the bottom of the funnel 202 is connected to multiple diversion pipes 203.

[0033] The overall effect of embodiment 2 is as follows: the support spring 201 can make slight movements at multiple angles while providing support for the funnel 202. When the frequency increases, the resulting shaking can shake the sand inside the funnel 202 to increase its flow rate and prevent the sand from sticking inside the funnel 202. The diversion pipe 203 is connected to the funnel 202 and can disperse the sand inside the funnel 202 to the surrounding areas, reducing the gap problem caused by the sand inside the mold.

[0034] Example 3, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, multiple push rod holes 11 are provided on the inner side of the upper and lower fixed frames 3, and the multiple push rod holes 11 are slidably connected to multiple sliding push rods 5. Multiple threaded holes 10 are provided on the inner side of the middle fixed frame 3, and the threaded holes 10 are threadedly connected to the threaded rods 9. Multiple vent holes 12 are provided on the inner side of the frame 1. A vent plug 13 is engaged at the bottom of the frame 1. A vent plug with the same number and size as the vent holes 12 is fixed on the vent plug 13. Two spring sliders 14 are fixedly connected to the outer side of the vent plug 13. A fixing hole 15 is provided on the inner side of the vent plug 13. A fixing bolt 16 is slidably connected inside the fixing hole 15. The other end of the fixing bolt 16 is fixedly connected to the fixed frame 3.

[0035] The effects achieved by the entire embodiment 3 are as follows: the threaded connection between the threaded hole 10 and the threaded rod 9 can realize the fine adjustment of the mold size, and the sliding connection between the multiple push rod holes 11 and the multiple sliding push rods 5 can reduce the size deviation caused by the displacement of the template 4 due to vibration. When the mold interior is too dense with sand and a vacuum effect is generated, the air hole plug 13 can be rotated outward by releasing the relationship between the fixing bolt 16 and the fixing hole 15. At this time, the air hole plug on the air hole plug 13 is pulled out from the vent hole 12, so that the mold interior loses the vacuum effect, which can increase the demolding speed. The spring slider 14 on the air hole plug 13 can increase the fixing stability of the air hole plug 13.

[0036] Example 4, as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, multiple temperature sensors 19 are fixedly connected to the inner side of the template 4, a signal transceiver 20 is fixedly connected to the top of the template 4, multiple indicator lights 21 are fixedly connected to the top of the signal transceiver 20, a movable base 17 is provided at the bottom of the frame 1, multiple casters 18 are fixedly connected to the bottom of the movable base 17, a rotating ring 8 is rotatably connected to the inside of the rotating hole 22, an anti-slip sleeve is provided on the outer side of the rotating wheel 7, a plug that is easy to install and remove is fixed at the bottom of the support spring 201, and a plug hole slightly larger than the plug size is opened at the corresponding position of the plug on the top of the template 4.

[0037] The overall effect of embodiment 4 is as follows: When the mixed sand is put into the mold and the mold needs to be taken out, in order to ensure the molding of the mold, a temperature sensor 19 is installed inside each template 4. The temperature of each part is received from the signal transceiver 20 and transmitted through the signal light 21. If the temperature on one side is still too high, the mold is likely not formed and cooling is required. The movable base 17 and the universal wheel 18 at its bottom can ensure that the mold can be moved easily when the sand mixer does not have a conveyor belt. The anti-slip sleeve is used to prevent the rotating wheel 7 from slipping and reduce the error caused by slippage when adjusting the mold size. The plug at the bottom of the support spring 201 and the plug hole at the top of the template 4 can easily and quickly install and remove the diversion mechanism 2, improving the working flexibility of the mold.

[0038] The working principle of the entire device is as follows: When this device is in actual use, if the mold size needs to be changed, there is no need to replace the mold. This is because the template 4 slides inside the frame 1, and a fixed frame 3 is fixed outside the frame 1. A sliding push rod 5 slides in the push rod hole 11 opened inside the fixed frame 3, and the sliding push rod 5 is fixed to the template 4. The other end of the sliding push rod 5 is fixed to a push plate 6, and a rotating wheel 7 and a rotating ring 8 rotate in the rotating hole 22 opened inside the push plate 6. The rotating wheel 7 and the rotating ring 8 are fixed, and a threaded rod 9 is fixed on the rotating wheel 7. The threaded rod 9 is connected to the push plate 4. The threaded hole 10 is connected, so the rotating wheel 7 is rotated. The rotating wheel 7 drives the threaded rod 9 on it to rotate inside the threaded hole 10. Because the rotating ring 8 is the limit, when the threaded rod 9 rotates and moves inward, it drives the push plate 6 to move inward through the rotating ring 8. The push plate 6 drives the sliding push rod 5 on it to move inward along the push rod hole 11. At this time, the template 4 is driven inward by the sliding push rod 5. By changing the distance between the four templates 4, the size of the mold can be changed, so that models of different sizes can be produced. To a certain extent, the utilization rate of the mold is improved, waste is reduced, and production efficiency is improved.

[0039] When the mold is in actual operation, if the mixed sand is too dry and the particles are too large, the sand will have poor flowability when poured into the mold, resulting in voids inside the mold. In this case, it is necessary to manually stir the sand inside the mold with a stirring rod, which increases the workload. Therefore, multiple support springs 201 are set on the top of the mold plate 4. The other end of the support springs 201 is fixed with a funnel 202. The funnel 202 is connected to a flow pipe that slopes outwards. When the mixed sand is discharged, it is poured into the funnel 202. At this time, the sand flows along the flow pipes to the four bottom corners of the mold, so that the sand can flow to the dead corners of the mold when it falls naturally, reducing the possibility of voids. When the flow rate of the sand in the funnel 202 slows down, the funnel 202 can be shaken manually to make the sand shake inside the funnel 202, increasing the flow rate. When shaking, the sand in the mold is more uniform, thereby reducing the possibility of voids in the mold caused by partial sand, which can lead to mold defects.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
