Description

Technical Field

[0001] This utility model belongs to the field of lost foam casting technology, specifically relating to a sand-adding device for lost foam casting. Background Technology

[0002] Lost foam casting (also known as solid foam casting) is a new casting method that involves bonding together paraffin or foam models similar in size and shape to the casting to form a model cluster. After coating with refractory paint and drying, the cluster is embedded in dry silica sand and vibrated to create the model. Under negative pressure, the casting is poured, causing the model to vaporize and the liquid metal to occupy the model's position. After solidification and cooling, the casting is formed. Because dry sand without binders often collapses during pouring, A. Wittemoser in Germany developed the so-called "magnetic mold casting" in 1967. Inspired by Nagano's invention of the V-method (vacuum casting) in Japan in 1971, today's lost foam casting also uses vacuum methods to fix the molding sand in many places. Therefore, lost foam casting technology has developed rapidly worldwide in the past 20 years.

[0003] In the process of lost foam casting, sand is usually added to provide vibration for mold shaping. Existing sand adding devices for lost foam casting usually use a bucket or loader to transport sand into the sand box, and then shake it manually. During the process, sand and dust are easily scattered, which has a negative impact on the user and affects the user's work efficiency. Therefore, we propose a sand adding device for lost foam casting. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a sand-adding device for lost foam casting, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sand-adding device for lost foam casting includes: a control console, a plurality of control buttons fixedly connected to the top of the control console, a control panel fixedly connected to the top of the control console, a sand and gravel box fixedly connected to the back of the control console, a plurality of connecting columns fixedly connected to the top of the sand and gravel box, a straight-through funnel fixedly connected to the top of the connecting columns, a heating plate fixedly connected to the bottom of the inner wall of the sand and gravel box, and a plurality of vibration components fixedly connected to the surface of the sand and gravel box, the positions of the vibration components matching the surface of the sand and gravel box.

[0007] Preferably, the plurality of vibration components include a connecting block, a connecting motor, a protective baffle, a rotating impact block, and a central rotating shaft. The connecting block is fixedly connected to the surface of the sand and gravel box, the connecting motor is fixedly connected to both sides of the connecting block, and the protective baffle is fixedly connected to one side of the plurality of central rotating shafts.

[0008] Preferably, the central rotating shaft is rotatably connected to one side of the plurality of connecting motors, and the plurality of rotating striking blocks are fixedly connected to the surface of the central rotating shaft, with the position of the rotating striking blocks matching the surface of the sand and gravel box.

[0009] Preferably, the fixing plate is fixedly connected to the top of the vibration assembly, and the position of the fixing plate matches that of the vibration assembly.

[0010] Preferably, a plurality of conductive rubber pads are fixedly connected to the surface of the sand and gravel box, and the positions of the conductive rubber pads are matched with the vibration component.

[0012] Preferably, the sand and gravel box has a sand outlet on its back, and the sand outlet matches the inner wall of the sand and gravel box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The vibration component is activated by controlling the console and other components. The structure of the vibration component vibrates the inside of the sand and gravel box. At the same time, a straight funnel is used to put sand and gravel into the sand and gravel box. Because the bottom of the straight funnel is directly connected to the inside of the sand and gravel box, and the inner wall of the sand and gravel box itself is high, sand and soil flying is greatly avoided, protecting the health of users and further improving the overall safety of the device. After the sand and gravel are put in, the heating plate is used to heat it, and the vibration component vibrates at the same time. No manual intervention is required during the process, which can greatly increase the user's work efficiency.

[0015] 2. The entire device is vibrated by the structure of the vibration components. Multiple vibration components are fixed to the surface of the sand and gravel box by connecting blocks. At the same time, the connecting motor is started to drive the rotation of the central shaft, which in turn drives the rotation of the rotating impact block. The rotating impact block is located on the surface of the sand and gravel box in three directions, so the sand and gravel inside the sand and gravel box can be vibrated and shaped from three parts, thereby further improving the overall functionality of the device. Moreover, manual vibration is not required, which improves the efficiency of manual work. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0027] A sand-adding device for lost foam casting includes: a control console 1, multiple control buttons 2 fixedly connected to the top of the control console 1, a control panel 3 fixedly connected to the top of the control console 1, a sand and gravel box 4 fixedly connected to the back of the control console 1, multiple connecting columns 5 fixedly connected to the top of the sand and gravel box 4, a straight-through funnel 6 fixedly connected to the top of the connecting columns 5, a heating plate 7 fixedly connected to the bottom of the inner wall of the sand and gravel box 4, and multiple vibration components 8 fixedly connected to the surface of the sand and gravel box 4, the positions of the vibration components 8 matching the surface of the sand and gravel box 4.

[0028] In this embodiment, two control buttons 2 are fixed on the top of the console 1, and a control panel 3 is fixed on the top of the console 1 near the back. A sand and gravel box 4 is fixed on the back of the console 1. The sand and gravel box 4 is a rectangular box, which allows for more even distribution of sand. Multiple connecting posts 5 are fixed at the four corners of the top of the sand and gravel box 4. A straight funnel 6 is fixed on the top of the multiple connecting posts 5. The bottom of the straight funnel 6 is set inside the sand and gravel box 4 to prevent dust from being generated when sand and gravel are poured in through the straight funnel 6, thereby further improving the overall safety of the device. At the same time, a heating plate 7 is fixed on the bottom of the inner wall of the sand and gravel box 4, and three vibration components 8 are fixed on the three surfaces of the sand and gravel box 4. The positions of the vibration components 8 match the surfaces of the sand and gravel box 4, and the vibration components 8 are distributed relatively evenly.

[0029] Multiple vibration components 8 include a connecting block 801, a connecting motor 802, a protective baffle 803, a rotating impact block 804, and a central rotating shaft 805. The connecting block 801 is fixedly connected to the surface of the sand and gravel box 4, the connecting motor 802 is fixedly connected to both sides of the connecting block 801, and the protective baffle 803 is fixedly connected to one side of the multiple central rotating shafts 805.

[0030] In this embodiment, the vibration component 8 is fixed to the surface of the sand and gravel box 4 by the connecting block 801, thereby providing a solid base for the overall fixation of the vibration component 8. At the same time, the connecting motor 802 is started, and the rotation of the connecting motor 802 provides a rotational basis for the operation of the vibration component 8. Meanwhile, the protective baffle 803 is fixedly connected to one side of multiple central rotating shafts 805, which can effectively separate the connecting motor 802, thereby further improving the safety of the vibration component 8.

[0031] The central shaft 805 is rotatably connected to one side of multiple connecting motors 802, and multiple rotating impact blocks 804 are fixedly connected to the surface of the central shaft 805. The position of the rotating impact blocks 804 matches the surface of the sand and gravel box 4.

[0032] In this embodiment, the central rotating shaft 805 is rotatably connected to one side of multiple connecting motors 802, and multiple rotating striking blocks 804 are fixed to the surface of the central rotating shaft 805. Therefore, after the connecting motors 802 drive the central rotating shaft 805 to rotate, they will drive the rotating striking blocks 804 to rotate. At the same time, the position of the rotating striking blocks 804 matches the surface of the sand and gravel box 4. Therefore, the rotation of the connecting motors 802 will drive the rotating striking blocks 804 to strike the surface of the sand and gravel box 4 to generate vibration, thereby improving the overall functionality of the device.

[0033] The fixing plate 9 is fixedly connected to the top of the vibration assembly 8, and the position of the fixing plate 9 matches that of the vibration assembly 8.

[0034] In this embodiment, the fixing plate 9 uses the fixing nails on its own surface to fix the vibration component 8 to the surface of the sand and gravel box 4 in a very firm manner. The fixing effect will not be reduced due to the vibration of the vibration component 8 itself, thereby further improving the overall stability of the device.

[0035] Multiple conductive rubber pads 10 are fixedly connected to the surface of the sand and gravel box 4, and the positions of the conductive rubber pads 10 are matched with the vibration component 8.

[0036] In this embodiment, the conductive rubber pad 10 is installed in the vibration part of the vibration component 8, which can transmit the vibration generated by the vibration component 8 to the inner wall of the sand and gravel box 4. Furthermore, due to its material, it can protect the surface of the sand and gravel box 4 from damage, thereby further improving the overall service life and functionality of the device.

[0037] Both sides of the vibration assembly 8 are fixedly connected to limit plates 11, and the size of the limit plates 11 matches that of the vibration assembly 8.

[0038] In this embodiment, the limiting plate 11 can effectively display the position of the internal components of the vibration assembly 8, prevent displacement and other situations from occurring, and further improve the overall functionality and safety of the device.

[0039] The sand and gravel box 4 has a sand outlet 12 on its back, which matches the inner wall of the sand and gravel box 4.

[0040] In this embodiment, the sand outlet 12 can be opened when the user needs to remove the sand and gravel, and the sand and gravel can be removed by gravity, thereby improving the overall functionality and flexibility of the device.

[0041] Working principle: Users can control the start of the vibration component 8 through the control panel 1 and other components. The structure of the vibration component 8 is used to vibrate the inside of the sand and gravel box 4. At the same time, the straight funnel 6 can be used to put sand and gravel into the sand and gravel box 4. Because the bottom of the straight funnel 6 is directly connected to the inside of the sand and gravel box 4, and the inner wall of the sand and gravel box 4 itself is high, it will greatly avoid sand and soil flying, protect the user's health, and further improve the overall safety of the device. After the sand and gravel are put in, the heating plate 7 is used to heat it, and the vibration component 8 vibrates at the same time. No manual intervention is required during the process, which can greatly increase the user's work efficiency.

[0042] Users can also vibrate the entire device through the structure of the vibration component 8. The connecting block 801 is used to fix multiple vibration components 8 to the surface of the sand and gravel box 4. At the same time, the connecting motor 802 is started to drive the rotation of the central rotating shaft 805, which in turn drives the rotation of the rotating striking block 804. The rotating striking block 804 is located in three directions on the surface of the sand and gravel box 4, so the sand and gravel inside the sand and gravel box 4 can be vibrated and shaped from three parts, thereby further improving the overall functionality of the device and eliminating the need for manual vibration, thus improving the efficiency of manual work.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
