In short, a mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts.

[0003] The inventor discovered in his daily use of the mold that when using the mold for molding, the well-proportioned liquid is usually poured into the lower mold, and the upper mold is pressed into the lower mold tightly against the surface of the liquid to form the object. Since bubbles will be generated inside the liquid when the liquid is poured into the lower mold, and since the mold is usually assembled with the upper mold pressed down to the surface of the liquid and then stopped, bubbles will be generated inside the molded object, which will cause an impact. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a combined mold.

When the mold needs to be used, a well-proportioned room temperature liquid is poured into the interior of the lower mold 1, and the upper mold 4 is covered on the surface of the lower mold 1. The upper mold 4 and the lower mold 1 are squeezed by the extrusion device 2 to discharge the bubbles in the liquid, so that there are no bubbles remaining inside the molded object.

[0029] Reference Figure 2-3The extrusion device 2 includes a rectangular block 21 arranged on the side of the lower mold 1, and a round rod 22 is provided on the top of the rectangular block 21. The top of the round rod 22 is rotatably connected to a rectangular plate 23. The surface of the rectangular plate 23 is threadedly connected to a threaded rod 24. One end of the threaded rod 24 is rotatably connected to an extrusion plate 26. Under the action of the extrusion plate 26 and the threaded rod 24, when forming an object, the threaded rod 24 can be rotated to make the extrusion plate 26 squeeze the upper mold 4, thereby discharging the bubbles inside the liquid, thereby avoiding the phenomenon of residual bubbles inside the object after molding. When the mold needs to be used, the room temperature liquid with a good ratio is poured into the interior of the lower mold 1, and the upper mold 4 is covered on the surface of the lower mold 1. The upper mold is pressed against the upper mold by the extrusion device 2. 4 is squeezed with the lower mold 1, thereby expelling the bubbles inside the liquid, so that no bubbles remain inside the molded object. The surface of the rectangular plate 23 is slidably connected with a slide rod 25, and one end of the slide rod 25 is fixedly connected with an extrusion plate 26. Under the action of the slide rod 25, the extrusion plate 26 will not rotate with the rotation of the threaded rod 24. The bottom of the extrusion plate 26 is fixedly connected with a pad 27. The pad 27 is a rubber block.

The surface of the rectangular block 21 is provided with a rectangular groove 29, and the interior of the rectangular groove 29 is fixedly connected with a fixing rod. The surface of the fixed rod is slidably connected with a slider, and the upper top of the slider is fixedly connected with a round rod 22. A clamping rod 28 is inserted into the side of the rectangular block 21. Under the action of the slider, the round rod 22 can be adjusted to its position, thereby preventing the extrusion plate 26 from only being able to squeeze the edge position of the upper mold 4, thereby achieving the effect of pushing the extrusion plate 26 to the extrusion position. Under the action of the clamping rod 28, the slider is moved to a suitable position for fixation. The side of the rectangular block 21 is fixedly connected with a fixing plate 210. The surface of the fixing plate 210 is threadedly connected with a bolt 211. One end of the bolt 211 is inserted into the interior of the lower mold 1. Under the action of the bolt 211, the extrusion device 2 can be disassembled when it is not in use. When room temperature liquid is poured into the mold for molding, the upper mold 4 is placed inside the lower mold 1, the rectangular block 21 is fixed to the side of the lower mold 1 by bolts 211, and the rectangular plate 23 is rotated on the surface of the round rod 22, and then the extrusion plate 26 is rotated to the surface of the upper mold 4, and the slider slides inside the rectangular groove 29 to adjust the extrusion position of the extrusion plate 26. When it is adjusted to the appropriate position, it is fixed by the clamping rod 28, and the threaded rod 24 is rotated. Under the action of the slide rod 25, the extrusion plate 26 moves downward, and under the action of the pad 27, the extrusion plate 26 will not directly contact the upper mold 4, avoiding the phenomenon of rigid contact, thereby achieving the phenomenon of extruding the upper mold 4 to discharge the bubbles inside the liquid.

The surface of the rod 36 is sleeved with a spring 37, and the two ends of the spring 37 are fixedly connected to the side surface of the lower mold 1 and the end of the positioning rod 36 away from the lower mold 1. Under the action of the spring 37, the positioning rod 36 is inserted into the interior of the protrusion 32 in a self-locking manner, thereby achieving a fixing effect. When the molds need to be spliced, the splicing frame 31 is inserted into the interior of the return groove 34 through the protrusion 32. Under the action of the annular groove 35 and the snap ring 33, the splicing frame 31 can be initially fixed to the upper top of the lower mold 1, thereby achieving the splicing effect. Under the action of the sealing ring 38, the liquid will not leak from the splicing of the splicing frame 31 and the lower mold 1. When the splicing is completed, under the action of the spring 37, the positioning rod 36 is inserted into the interior of the protrusion 32 in a self-locking manner, thereby achieving a fixing effect, thereby achieving the splicing effect.

When the room temperature liquid is poured into the mold for molding, the upper mold 4 is placed inside the lower mold 1, and the rectangular block 21 is fixed to the side of the lower mold 1 by the bolt 211, and the rectangular plate 23 is rotated on the surface of the round rod 22, and then the extrusion plate 26 is rotated to the surface of the upper mold 4, and the slider is slid inside the rectangular groove 29 to adjust the extrusion position of the extrusion plate 26. When it is adjusted to the appropriate position, it is fixed by the clamping rod 28 and the threaded rod 2 is rotated. 4. Under the action of the slide bar 25, the extrusion plate 26 moves downward, and under the action of the pad 27, the extrusion plate 26 will not directly contact the upper mold 4, avoiding the phenomenon of rigid contact, thereby achieving the phenomenon of squeezing the upper mold 4 to discharge the bubbles inside the liquid. When it is necessary to splice the mold, the splicing frame 31 is inserted into the inside of the return groove 34 through the protrusion 32. Under the action of the annular groove 35 and the snap ring 33, the splicing frame 31 can be initially fixed to the upper top of the lower mold 1, thereby achieving the effect of splicing.
