Embodiment 1

[0022] see Figure 1-3 , a fastening mechanism for a casting mold, comprising three mold main bodies 1, characterized in that: both sides of the three mold main bodies 1 are fixedly connected with a support plate 2, and the surface of the support plate 2 is movably connected with a fixed rod 3, supporting The surface of the plate 2 is provided with a card slot suitable for the fixed rod 3, and the surface of the fixed rod 3 near the top is rotatably connected with the movable shaft 4, and the surface of the movable shaft 4 is fixedly connected with an arc-shaped clamping rod 5, and the curved clamping rod 5 The surface of the fixed rod 3 is provided with an elastic rubber pad, and the arc-shaped clamping rod 5 is clamped with the surface of the support plate 2 through the elastic rubber pad, and the bottom end of the fixed rod 3 is movably connected with an arc-shaped strut 6 through a rotating shaft, and the arc-shaped strut 6 The bottom end is fixedly connected to the top su...

Embodiment 2

[0025] see Figure 4 , the inside of the support plate 2 is provided with a control chamber 10, the inside of the control chamber 10 and the inflatable chamber 7 are fixedly connected with a support frame 11, and the front shape of the support frame 11 is X-shaped, and the inside of the control chamber 10 and the inflatable chamber 7 are uniform. A shrinkable airbag 12 is provided, and the interior of the shrinkable airbag 12 is filled with lubricating oil, and a check valve is provided on the surface of the shrinkable airbag 12 .

[0026] The difference from Embodiment 1 is that the inside of the inflatable cavity 7 can be reinforced through the support frame 11 and the shrinkable air bag 12, and at the same time, it is ensured that the gas inside the inflatable cavity 7 can be squeezed and contracted after the gas is expanded by heat, thereby leaving a suitable space. space, cooperate with the support frame 11 to ensure the firmness of the arc clamping rod 5 as a whole.

Embodiment 3

[0028] see Figure 5-6 , the inner wall of the control chamber 10 is fixedly connected with a clamping sleeve 13, and the inner wall of the clamping sleeve 13 is movably connected with a clamping piston 14. The inside of the clamping sleeve 13 communicates with an air delivery tube 15, and the end of the air delivery tube 15 away from the clamping sleeve 13 communicates with the inside of the control chamber 10. The bottom surface of the support plate 2 is inlaid with a pressing sleeve 16, and the pressing sleeve The inner wall of the pipe 16 is movably connected with a pressing piston 17, and the bottom surface of the pressing piston 17 is movably connected with the upper surface of the arc-shaped strut 6, and the upper surface of the arc-shaped strut 6 is provided with a horizontal groove matching the pressing piston 17 to support The bottom surface of the plate 2 is inlaid with a buffer sleeve 18, and the inner wall of the buffer sleeve 18 is movably connected with a buffer...

Abstract

The invention discloses a buckling mechanism of a casting mold. The buckling mechanism of the casting mold comprises three mold main bodies. Supporting plates are fixedly connected to the two sides ofthe three mold main bodies correspondingly, fixing rods are movably connected to the surfaces of the supporting plates, clamping grooves matched with the fixing rods are formed in the surfaces of thesupporting plates, the surfaces, close to the top ends, of the fixed rods are rotationally connected with movable shafts, and the surfaces of the movable shafts are fixedly connected with arc-shapedclamping rods. According to the buckling mechanism of the casting mold, through an inflation cavity and the arc-shaped clamping rods, after the arc-shaped clamping rods are clamped on the supporting plates, if cracks appear on the surfaces of the arc-shaped clamping rods, gas in the inflation cavity can leak into sealant covers from the cracks, so that soft rubber sheets gradually protrude, an operator can feel the protrusions after holding the arc-shaped clamping rods with hands, the positions where the cracks appear on the surfaces of the arc-shaped clamping rods can be rapidly found, the arc-shaped clamping rods can be disassembled and replaced in time, and the effect of avoiding affecting normal production of parts is achieved.

Description

technical field [0001] The invention relates to the technical field of casting molds, in particular to a fastening mechanism for casting molds. Background technique [0002] In the production process of metal parts, it is often necessary to pour the molten metal solution into the mold for molding, and the sand mold is a commonly used one in the daily production process, which can put the prepared wet sand into the mold The corresponding shape is pressed to facilitate the subsequent pouring of molten metal and ensure the normal production of different metal parts. [0003] Most of the existing sand casting molds are composed of two layers and three layers, and the multi-layer molds often need to use the corresponding fastening mechanism to fix them, but most of the fastening mechanisms are easy to appear on the surface after long-term use. Check the cracks, so it is easy to accidentally break during the fastening process and cannot be fastened firmly, which will affect the n...
