[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1 , an embodiment provided by the present utility model: A die for the upper shell of a gas meter includes a base 4. A lower die 1 is fixedly connected to the top of the base 4. An upper die 2 is inserted into the top of the lower die 1. By inserting the upper die 2 into the lower die 1, the inner walls of the lower die 1 and the upper die 2 form the shape of the upper shell of the gas meter. By injecting metal solution into the inside of the lower die 1 and the upper die 2, the upper shell of the gas meter is die-cast. An injection pipeline 3 can be installed and disassembled on the top of the upper die 2. Through the injection pipeline 3, the metal solution is injected into the upper die 2.

The bottom end of the connecting rod 52 is fixedly connected to a square plate 53. Through the moving effect of the square plate 53, the connecting rod 52 is driven to move vertically. A support frame 54 is fixedly connected to the bottom of the square plate 53. Through the moving effect of the support frame 54, the square plate 53 is driven to move vertically. A telescopic rod 55 is hinged to the front of the support frame 54. The telescopic rod 55 is a prior art and has the effects of contraction and extension.

[0034] Refer to Figure 4 , the assembling and disassembling assembly 6 includes a fixing block 61. An annular sleeve 63 is inserted into the outer wall of the fixing block 61. Through the insertion effect of the fixing block 61 and the annular sleeve 63, the upper mold 2 can be installed on the injection pipe 3. A sealing gasket 62 is arranged on the inner wall of the annular sleeve 63. Through the extrusion of the fixing block 61 and the annular sleeve 63 on the sealing gasket 62, the sealing gasket 62 is deformed by expansion, so as to seal the gap between the fixing block 61 and the annular sleeve 63. A wedge block 66 is elastically connected to the right inner wall of the fixing block 61 through a limiting spring 65. Through the elastic force of the limiting spring 65, the wedge block 66 always maintains the clamping effect with the square groove 64 without external force, so as to limit the annular sleeve 63.

[0035] Refer to Figure 1 and Figure 3 , a fixing plate 58 is fixedly connected to the front of the base 4. Through the fixing effect of the fixing plate 58, the fixing plate 58 is prevented from falling off. Two groups of clamping grooves 59 are opened on the right side of the fixing plate 58. Through the clamping effects of the two groups of clamping grooves 59 and the clamping blocks 56 at different positions, the telescopic rod 55 is limited at different positions. A clamping block 56 is elastically connected to the right inner wall of the telescopic rod 55 through a spring 57. Through the elastic force of the spring 57, the clamping block 56 always maintains the clamping effect with the clamping groove 59 without external force, so as to limit the telescopic rod 55.

[0036] Refer to Figure 2 , the outer circumference of the connecting rod 52 penetrates and is slidably connected to the bottom inner wall of the lower mold 1. Through the sliding effect of the connecting rod 52, the top plate 51 is driven to move vertically. The outer wall of the telescopic rod 55 is hinged to the front inner wall of the base 4. Through the hinged effect of the telescopic rod 55, the telescopic rod 55 can rotate around the hinge point.

[0037] Refer to Figure 4, the bottom of the fixing block 61 is fixedly connected to the top of the upper mold 2. Through the fixing effect of the fixing block 61, the fixing block 61 is prevented from falling off. The top of the annular sleeve 63 is fixedly connected to the bottom end of the injection pipe 3. Through the fixing effect of the annular sleeve 63, the annular sleeve 63 is prevented from falling off. One end of the limiting spring 65 is fixedly connected to the right inner wall of the fixing block 61, and the other end of the limiting spring 65 is fixedly connected to the outer wall of the wedge block 66. Through the fixing effect of the limiting spring 65, the wedge block 66 is kept fixed and prevented from falling off.

[0038] Refer to Figure 3 , one end of the spring 57 is fixedly connected to the right inner wall of the telescopic rod 55, and the other end of the spring 57 is fixedly connected to the left side of the clamping block 56. Through the fixing effect of the spring 57, the clamping block 56 is kept fixed and prevented from falling off.

[0039] Refer to Figure 4 , the outer wall of the wedge block 66 is slidably connected to the right inner wall of the fixing block 61. Through the sliding effect of the wedge block 66, the wedge block 66 is engaged or disengaged with the square groove 64. The outer wall of the wedge block 66 is engaged with the inner wall of the square groove 64. Through the engagement effect of the wedge block 66 and the square groove 64, the fixing block 61 limits the annular sleeve 63.

[0040] Refer to Figure 3 , the outer wall of the clamping block 56 is slidably connected to the right inner wall of the telescopic rod 55. Through the sliding effect of the clamping block 56, the clamping block 56 is engaged or disengaged with the clamping groove 59. The outer wall of the clamping block 56 is engaged with the inner wall of the clamping groove 59. Through the engagement effect of the clamping block 56 and the clamping groove 59, the fixing plate 58 limits the telescopic rod 55.

[0041] Working principle: When the staff needs to die-cast the upper shell of the gas meter, the fixing block 61 arranged at the top of the upper mold 2 is inserted into the annular sleeve 63 arranged at the bottom end of the injection pipe 3 by the staff, so that the wedge block 66 is engaged with the square groove 64 under the elastic force of the limiting spring 65, thereby limiting the annular sleeve 63. At the same time, the sealing gasket 62 is extruded by the fixing block 61 and the annular sleeve 63, so that the sealing gasket 62 seals the gap between the fixing block 61 and the annular sleeve 63, and the upper mold 2 is fixedly installed on the injection pipe 3.

[0042] The upper mold 2 is inserted into the lower mold 1 by the staff, and the metal solution is injected into the upper mold 2 and the lower mold 1 through the injection pipeline 3, so as to complete the die-casting molding of the upper shell. After the molding is completed, the staff opens the upper mold 2 and presses the latch 56, so that the latch 56 releases the latching effect with the clamping groove 59 and at the same time releases the limiting effect on the telescopic rod 55. The telescopic rod 55 is rotated downward, so that the support frame 54 drives the square plate 53 to move upward, so that the connecting rod 52 drives the top plate 51 to move upward, and the formed upper shell is ejected, completing the demolding of the upper shell. The telescopic rod 55 is rotated upward to reset the top plate 51. At the same time, under the elastic action of the spring 57, the latch 56 is latched with the clamping groove 59 to limit the telescopic rod 55, so that the top plate 51 remains fixed.

[0043] After the mold is used up, the staff presses the wedge block 66, so that the wedge block 66 releases the latching effect with the square groove 64 and at the same time releases the limiting effect on the annular sleeve 63. The staff can remove the upper mold 2 for maintenance and storage.
