[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides a metal die-casting mold that is easy to demold, including a lower mold 1, a first motor 2 is fixedly installed on the bottom of the lower mold 1, a screw 3 is fixedly installed on the output end of the first motor 2, a connecting plate 4 is engaged with the outer side of the screw 3, an upper mold 7 is fixedly installed on the right side of the connecting plate 4, a sealing plate 8 is fixedly installed on the bottom of the upper mold 7, a feed port 9 is fixedly installed above the upper mold 7, a casting cavity 5 and a sealing groove 6 are opened inside the lower mold 1, the casting cavity 5 is located on the inner side of the sealing groove 6, the sealing plate 8 is located inside the sealing groove 6, and the sealing plate 8 and the sealing groove 6 are plug-in.

[0021] The shape of the interior of the casting cavity 5 can be adjusted. When it is necessary to cast materials of different shapes, the interior of the casting cavity 5 is opened into the required shape. After the casting solidifies, the desired finished product will be obtained, thereby achieving the effect of casting objects of different shapes. At the same time, the sealing plate 8 seals the outside of the casting cavity 5 to prevent liquid from overflowing during casting.

[0022] A fixing rod 10 is fixedly installed above the lower mold 1 , a sliding groove 11 is provided inside the fixing rod 10 , a slider 12 is slidably connected inside the sliding groove 11 , and the slider 12 is fixedly connected to the connecting plate 4 .

[0023] Start the first motor 2 to drive the screw 3 to rotate, so that the screw 3 is engaged with the connecting plate 4, so that the upper mold 7 can move up and down. At this time, since the slider 12 is fixedly connected to the connecting plate 4,

[0024] Among them, a fixed plate 13 is fixedly installed at the bottom of the lower mold 1, a second motor 14 is fixedly installed on the left side of the fixed plate 13, a fixed shaft 15 is fixedly installed on the output end of the second motor 14, the outer side of the fixed shaft 15 is connected to the conveyor belt 16 for transmission, and a fixed block 17 is fixedly installed on the outer side of the conveyor belt 16.

[0025] The second motor 14 is started to drive the fixed shaft 15 to rotate, so that the conveyor belt 16 can be quickly transmitted, so as to achieve the effect of causing the fixed block 17 to have a displacement effect.

[0026] The interior of the fixed block 17 is rotatably connected to a connecting shaft 18 , the exterior of the connecting shaft 18 is rotatably connected to a fixing sleeve 19 , a support rod 20 is fixedly installed above the fixing sleeve 19 , and a billiard ball 21 is fixedly installed on the end of the support rod 20 away from the fixing sleeve 19 .

[0027] The billiard ball 21 is a sphere with a certain weight. At the same time, the height of the billiard ball 21 is higher than the bottom height of the lower mold 1, so as to achieve the effect of impacting the front of the lower mold 1 to generate vibration.

[0028] Among them, a telescopic rod 22 is fixedly installed on the outside of the support rod 20, and a return spring 23 is sleeved on the outside of the telescopic rod 22. The principle of the return spring 23 ensures that one end of the support rod 20 is fixedly connected to the conveyor belt 16.

[0029] The return spring 23 always provides elastic force to keep the support rod 20 and the conveyor belt 16 vertical. When the billiard ball 21 collides with the lower mold 1, the bottom of the lower mold 1 will squeeze the billiard ball 21. At this time, the telescopic rod 22 will shrink toward the direction of the conveyor belt 16, thereby achieving the effect of facilitating the movement of the billiard ball 21 at the bottom of the lower mold 1.

[0030] Among them, a limit ring 24 is fixedly installed on the top of the screw 3, and a limit sleeve 25 is sleeved on the outer side of the screw 3. The limit sleeve 25 is fixedly connected to the connecting plate 4, and the limit sleeve 25 is located above the connecting plate 4.

[0031] The limiting ring 24 is spherical, and its diameter is greater than the diameter of the screw 3. Its main function is to limit the connecting plate 4 to prevent the connecting plate 4 from rotating too many times and causing the upper mold 7 to fall off.

[0032] The working principle and use process of this utility model:

[0033] First, the first motor 2 is started to drive the screw 3 to rotate, so that the screw 3 is engaged with the connecting plate 4, so that the upper mold 7 moves downward, and at the same time, the sealing plate 8 is inserted into the sealing groove 6 to seal the surrounding of the casting cavity 5;

[0034] Secondly, since a fixed shaft 15 is fixedly installed at the output end of the second motor 14, a conveyor belt 16 is connected to the outer side of the fixed shaft 15 for transmission, a fixed block 17 is fixedly installed above the conveyor belt 16, and a connecting shaft 18 is rotatably connected inside the fixed block 17, and a fixed sleeve 19 is sleeved on the outer side of the connecting shaft 18, after the second motor 14 is started to drive the fixed shaft 15 to rotate, the conveyor belt 16 can drive the connecting shaft 18 to move. At the same time, since a support rod 20 is fixedly installed on the end of the fixed sleeve 19 away from the conveyor belt 16, a billiard ball 21 is fixedly installed on the end of the support rod 20 away from the fixed sleeve 19, after the conveyor belt 16 is driven, the billiard ball 21 will collide with the front of the lower mold 1, so that when the liquid material is poured into the casting cavity 5 from the inside of the feed port 9, the collision between the billiard ball 21 and the lower mold 1 generates vibration, which makes the liquid raw material inside the casting cavity 5 become uniform, and the bubbles inside it are also discharged, so as to achieve the effect of ensuring the quality of the product after the casting is completed;

[0035] At the same time, since a sliding groove 11 is provided inside the fixed rod 10, a slider 12 is slidably connected inside the sliding groove 11, and the slider 12 is fixedly connected to the connecting plate 4, after the first motor 2 is started to drive the lead screw 3 to rotate, the connecting plate 4 will engage with the lead screw 3. At this time, the upper mold 7 will move up and down through the sliding action of the slider 12 and the sliding groove 11 and the limiting action of the slider 12 and the sliding groove 11, and the stability of the movement is never maintained;

[0036] Finally, when the product solidifies, the collision between the billiard ball 21 and the lower mold 1 is continued to cause the lower mold 1 to shake, thereby making the product easier to demould.

[0037] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
