Description

Technical Field

[0001] The invention relates to the technical field of silica-molybdenum brick forming, in particular to a mold forming device for silica-molybdenum brick production. Background Art

[0002] Silica-mullite bricks are a high-performance refractory material made primarily of mullite and silicon carbide. Produced through high-temperature sintering, they exhibit excellent high-temperature strength, wear resistance, and thermal shock resistance. They are widely used in the production of cement, steel, glass, ceramics, and power industries. During production, these bricks are formed using molds, followed by sintering. Hydraulic molding machines are commonly used, utilizing hydraulic pressure to ensure compactness.

[0003] When using a hydraulic forming machine, after raw material is loaded into the forming cavity of the lower die, the hydraulic cylinder is activated to lower the upper die, and the ram is used to hydraulically form the material. After the brick is formed, it is ejected by the ejection mechanism, which then pushes the brick to move. In existing hydraulic forming machines, the lower die is fixed while the ejection mechanism is in action, resulting in significant static friction between the lower die and the brick. This high static friction can easily damage the brick during the initial ejection process, affecting the brick forming rate and increasing production costs. Summary of the Invention

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figures 1-6 As shown, a mold forming device for producing silicon mullite bricks includes a base 1, a pillar 2 is fixed on the base 1, and a top plate 3 is installed on the top of the pillar 2, an upper template 4 is sleeved on the pillar 2, a forming block 5 is fixed to the lower surface of the upper template 4, a hydraulic oil cylinder 6 is fixed on the top plate 3, a lower mold structure 7 is installed on the base 1, and a cross plate 8 is fixed on the base 1, and a top material structure 9 in contact with the lower mold structure 7 is provided on the base 1. The lower mold structure 7 is used in conjunction with the forming block 5 to press and form multiple silicon mullite bricks at one time, with high production efficiency. The cross plate 8 is used to ensure the fixity of the driving part in the top material structure 9, and the hydraulic oil cylinder 6 can provide sufficient hydraulic force to ensure that the pressed silicon mullite bricks have high density and will not be loose.

[0018] A support plate 10 is fixed to the base 1, and a feed plate 16 is provided at the front end of the base 1. A discharge hopper 17 is provided at the lower end of the feed plate 16, and a discharge hole 18 is provided on the feed plate 16. Guide rods 11 are provided on the support plate 10 and the feed plate 16, and a feed hopper 12 is provided on the support plate 10. Drive plates 13 are provided at both ends of the feed hopper 12, and the drive plates 13 are sleeved on the guide rods 11. A fixed base 14 is mounted on the support plate 10, and a multi-stage telescopic cylinder 15 is installed on the fixed base 14. The movable shaft of the multi-stage telescopic cylinder 15 is connected to the drive plate 13.

[0019] A feeding hole 18 is provided on the feeding plate 16. After the silica bricks are pressed and ejected, they are pushed by the movable feeding hopper 12. The silica bricks and the powdered raw materials move on the feeding plate 16. The powdered raw materials pass through the feeding hole 18 and enter the discharge hopper 17. This can separate the bricks from the powdered raw materials and collect the powdered raw materials to avoid waste. The bricks are pushed by the feeding hopper 12 without the need for additional pushing materials. The use is flexible and convenient.

[0020] When pressing and forming silica-molybdenum bricks, the entire equipment is stably placed on the base 1, and powder raw materials are added to the feed hopper 12, and then the pressing and forming work is carried out. After starting the equipment, the multi-stage telescopic cylinder 15 installed through the fixed base 14 is put into operation. The movable shaft of the cylinder drives the drive plate 13 to move along the guide rod 11, thereby moving the feed hopper 12. When the feed hopper 12 moves to the lower mold structure 7 on the base 1, the powder material falls into the lower mold structure 7 for filling. Then the multi-stage telescopic cylinder 15 is operated to move the feed hopper 12 to reset. During this process, the feed hopper 12 acts as a scraper to ensure that the filled powder material is flush with the upper surface of the base 1.

[0021] After the material is filled, the hydraulic cylinder 6 on the top plate 3 on the pillar 2 is started, and the cylinder shaft of the hydraulic cylinder 6 is extended, thereby carrying the upper template 4 and the forming block 5 down, and the forming block 5 presses and forms the material at the lower mold structure 7. Under the joint action of the forming block 5, the lower mold structure 7 and the top material structure 9, the brick blank is pressed and formed. Then the hydraulic cylinder 6 runs again to carry the upper template 4 and the forming block 5 up and reset, and the top material structure 9 starts to carry out the top material work of the silicon molybdenum brick blank. In the initial stage of top material, the top material structure 9 knocks on the vibrating part in the lower mold structure 7, causing the lower mold structure 7 to vibrate slightly. When used in conjunction with the top material structure 9, top material can be carried out quickly to avoid the normal top material being affected by the large static friction between the brick blank and the lower mold structure 7. After the bricks are ejected, the multi-stage telescopic cylinder 15 is activated again, and the feed hopper 12 moves to the base 1. During this process, the feed hopper 12 pushes the bricks forward, causing them to move to the feed plate 16, while also performing the filling work. The material can be pushed while filling, and no additional drive source is required to achieve the pushing work. The bricks that have moved to the feed plate 16 are removed, and the excess powdered raw materials fall into the discharge hopper 17 through the drop hole 18. Finally, they are discharged and collected from the port of the discharge hopper 17 and can be used again, avoiding waste and saving production costs.

[0022] According to the above embodiment, the lower mold structure 7 includes a lower mold body 701, a cavity 702 and a support boss 703. The cavity 702 is provided on the lower mold body 701, and the support boss 703 is provided at the bottom end of the cavity 702 on the lower mold body 701. The lower mold structure 7 also includes a connecting rod 704, a connecting plate 705, a holding spring 706 and a vibration assembly 707. The connecting rod 704 and the connecting plate 705 are fixedly connected, and the connecting rod 704 passes through the base 1. The upper end of the connecting rod 704 is fixedly connected to the lower mold body 701. The holding spring 706 is sleeved on the connecting rod 704, and the two ends of the holding spring 706 contact the base 1 and the connecting plate 705 respectively. The vibration assembly 707 is installed on the connecting plate 705.

[0023] When the lower mold structure 7 is used in conjunction with the forming pressing block 5 to complete the molding and pressing of the silicon mullite brick blank, the top material part in the top material structure 9 is located at the bottom of the cavity 702 on the lower mold body 701, and the support boss 703 is used for limiting support. When the feed hopper 12 is filled, the powder material enters the cavity 702 and is supported by the top material part in the top material structure 9. During the molding process, the molding pressing block 5 enters the cavity 702 on the lower mold body 701. Under the joint action of the molding pressing block 5, the lower mold body 701 and the top material structure 9, the silicon mullite brick blank is pressed and formed. When pushing the material, the structure in the pushing structure 9 knocks the vibration component 707 on the connecting plate 705, and the vibration component 707 generates vibration and transmits it to the connecting plate 705. The connecting plate 705 transmits the force to the lower mold body 701 through the connecting rod 704, and is used in conjunction with the tightening spring 706 to make the lower mold body 701 form a slight vibration, and the vibration is a vertical vibration. Under the action of vibration, the static friction between the lower mold body 701 and the brick blank becomes smaller, which facilitates the pushing work and can prevent the damage of the brick blank caused by excessive static friction, thereby ensuring the integrity of the brick blank.

[0024] The vibration assembly 707 includes a mounting seat 7071, a fixed plate 7072, a movable rod 7073, a vibration block 7074, an elastic plate 7075, an adjusting plate 7076, a vibration spring 7077 and an adjusting bolt 7078. The mounting seat 7071 and the fixed plate 7072 are fixedly connected, and the mounting seat 7071 is installed on the connecting plate 705. The movable rod 7073 and the vibration block 7074 are fixedly connected, and a limit block is provided at the upper end of the movable rod 7073. The movable rod 7073 passes through the fixed plate 7072. The elastic plate 7075 is fixedly connected to the vibration block 7074. The adjusting plate 7076 and the vibration spring 7077 are sleeved on the movable rod 7073, and the lower end of the vibration spring 7077 contacts the vibration block 7074. The adjusting bolt 7078 is threadedly connected to the fixed plate 7072, and the lower end of the adjusting bolt 7078 contacts the adjusting plate 7076.

[0025] When installing the vibration assembly 707, the mounting base 7071 is clamped onto the connecting plate 705 and fixed with screws. The movable rod 7073 with a limit block passes through the fixed plate 7072. A vibration spring 7077 is sleeved on the lower end of the movable rod 7073. At the same time, the lower end of the movable rod 7073 is connected to the vibration block 7074 via a threaded joint, thereby completing the installation of the vibration assembly 707. During use, in the initial stage of pushing the material, the lifting structure 9 rises and causes the end of the elastic plate 7075 to strike. The elastic plate 7075 vibrates under the impact. In combination with the vibration spring 7077 on the vibration block 7074, a large vibration effect is generated. The vibration effect is transmitted through the entire vibration assembly 707 and ultimately transmitted to the lower mold body 701, causing the lower mold body 701 to vibrate slightly, thereby overcoming the static friction between the brick and the lower mold body 701 and facilitating the pushing of the material.

[0026] When necessary, the adjusting bolt 7078 on the fixed plate 7072 can be rotated to cooperate with the vibration spring 7077 to change the height of the adjusting plate 7076, so as to adjust the compression degree of the vibration spring 7077, thereby changing the vibration effect of the entire vibration assembly 707, which is highly flexible and adaptable to use.

[0027] Through the above implementation scheme, the ejection structure 9 includes a ejection rod 901, a ejection plate 902, a synchronization plate 903, a knocking block 904 and a ejection cylinder 905. The ejection rod 901 and the ejection plate 902 are fixedly connected, and the ejection plate 902 is located in the lower mold structure 7. The synchronization plate 903 is connected to the lower end of the ejection rod 901, and the synchronization plate 903 is fixedly connected to the knocking block 904. The ejection cylinder 905 is installed on the horizontal plate 8, and the telescopic shaft of the ejection cylinder 905 is fixedly connected to the synchronization plate 903.

[0028] When the ejection structure 9 is used to eject the bricks, the ejection cylinder 905 on the horizontal plate 8 is activated, and the telescopic shaft of the ejection cylinder 905 moves to move the synchronous plate 903 upward. Under the action of the synchronous plate 903, all the ejection rods 901 rise synchronously on the base 1, thereby moving all the ejection plates 902 upward to perform the ejection work. In the initial stage of the rise of the synchronous plate 903, the knocking block 904 set at the end of the synchronous plate 903 contacts the lower mold structure 7, generating a knocking vibration. The vibration can be generated at the moment of ejection, overcoming the static friction between the lower mold structure 7 and the brick, and the ejection work can be completed normally and quickly.

[0029] It should be noted that, through the setting of the lower mold structure 7, a connecting rod 704, a connecting plate 705 and a holding spring 706 are set at the lower end of the lower mold body 701, which are used in conjunction with the vibration component 707. During the press molding process, due to the action of the holding spring 706, the lower mold body 701 has good stability, which ensures the molding effect. When the material is ejected, the knocking block 904 in the ejection structure 9 generates a force on the elastic plate 7075 in the vibration component 707. In the initial stage of ejection, the elastic plate 7075 and the vibration spring 7077 in the vibration component 707 can be used to form a vibration effect, so that the lower mold body 701 is slightly vibrated by the holding spring 706, which can overcome the vibration between the lower mold body 701 and the vibration component 707. The static friction of the product can quickly push the material while avoiding damage to the bricks. The vibration component 707 is provided with an adjustment bolt 7078, which can adjust the position of the adjustment plate 7076, thereby changing the compression degree of the vibration spring 7077 and adjusting the vibration frequency and amplitude. It is flexible and adaptable to use. The jacking structure 9 uses a synchronous plate 903, which can synchronously move the jacking rod 901 to achieve the effect of synchronous jacking of all bricks. The jacking plate 902 is set in the cavity 702 and serves as the bottom plate of the cavity 702 during the molding and pressing process to ensure the molding effect. The support boss 703 at the lower end of the cavity 702 limits the jacking plate 902 to ensure that the pressed bricks are of the same model. The knocking block 904 is symmetrically set on the synchronous plate 903. When used with two sets of vibration components 707, the two sets of vibration components 707 can be knocked synchronously to ensure the use effect.
