Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold for casting a housing of a reclosing circuit breaker. Background Art

[0002] A casting mold is a mold used to make concrete or other building materials. During the construction process, concrete needs to be poured into the mold and then waited for it to solidify and take shape. Casting molds can be designed and customized according to different needs, such as wall molds, column molds, beam molds, etc. During the pouring process, it is necessary to pay attention to factors such as the concrete ratio, pouring method and pouring sequence to ensure that the concrete in the mold can be fully filled and can obtain the required shape and strength. After the pouring is completed, it is necessary to wait for a certain amount of time for the concrete to fully harden, and then the mold can be removed to make the building material completely formed. Casting molds play an important role in construction and can help achieve the accurate shape and good quality of the building structure.

[0003] When manufacturing the mold for the housing of the reclosing circuit breaker, the model needs to be demoulded after pouring. However, in order to ensure its airtightness, the molded model and the mold will fit very tightly, which makes it inconvenient to demould after pouring. If the demoulding is excessively knocked, it is likely to cause damage to the model. Utility Model Content

The impact force during lifting causes the cast circuit breaker model and the lower mold base to loosen, making it easier to demould.

[0015] 2. When the lower die seat is pushed downward by the upper die seat, the lower die seat will drive the connecting pipe and the piston rod to move downward together, so that the piston rod pushes the piston plate relatively, and then the coolant in the piston rod enters the cooling chamber, so that the mold is cooled from the inside, the bottom of the mold is cooled more evenly, and it is easier to demold.

[0022] The lower die seat 21 penetrates the connecting seat 1 and is slidably connected. The side of the lower die seat 21 is fixedly connected with an insertion rod 22. The insertion rod 22 penetrates the connecting seat 1 and is slidably connected. A square hole 23 is provided at the bottom end of the insertion rod 22. A contraction rod 24 is penetrated on the inner side of the square hole 23. A triangular block 25 is fixedly connected to the end of the contraction rod 24 away from the inner side of the square hole 23. A spring 26 is fixedly connected to the triangular block 25 and the inner side of the square hole 23. When the lower die seat 21 is embedded in the connecting seat 1, the insertion rod 22 will be inserted into the connecting seat 1 at the same time. When the inclined surface of the triangular block 25 contacts the inner side of the connecting seat 1, it will contract into the square hole 23 and compress the spring 26. The card slot 27 is provided on the inner side of the connecting seat 1. After the lower die seat 21 is fully engaged with the connecting seat 1, the triangular block 25 is just aligned with the slot 27, and the compressed spring 1 26 will push the triangular block 25 into the slot 27. A movable cavity 28 is opened on the left side of the slot 27, and a slide plate 29 is slidably connected to the inner side of the movable cavity 28. A resistance rod 210 runs through the surface of the slide plate 29. The upper mold base 3 is pulled up by the casting equipment. When the upper mold base 3 is just raised, the lower mold base 21 cannot be raised together with the upper mold base 3 because the triangular block 25 is stuck in the slot 27. However, after the upper mold base 3 is raised for a distance, the inclined surface of the hinge block 215 will resist the resistance rod 210, so that the resistance rod 210 pushes the triangular block 25 to shrink and no longer get stuck in the slot 27. A spring 211 is fixedly connected between the slide plate 29 and the inner side of the movable cavity 28. The linkage rod 212 is fixedly connected to the side of the upper die seat 3, and a contraction groove 213 is provided on the inner side of the linkage rod 212. A support rod 214 is fixedly connected to the inner side of the contraction groove 213. The support rod 214 penetrates and is rotatably connected to a hinge block 215. When the upper die seat 3 moves downward, the hinge block 215 will contact the inclined surface of the contact rod 210 and contract into the contraction groove 213. At the same time, the torsion spring 217 is compressed. When the hinge block 215 moves to the bottom of the contact rod 210, the compressed torsion spring 217 pushes out the hinge block 215. A limited block 216 is fixedly connected to the inner side of the linkage rod 212, and a torsion spring 217 is fixedly connected between the hinge block 215 and the inner side of the contraction groove 213. The cooling part 5 includes a cooling chamber 51, which is opened inside the lower die base 21. A connecting pipe 52 is passed through and fixedly connected to the bottom of the cooling chamber 51. When the lower die base 21 is pushed downward by the upper die base 3, the lower die base 21 will drive the connecting pipe 52 and the piston column 53 to move downward together, so that the piston rod 55 pushes the piston plate 54 relatively, and then the coolant in the piston column 53 enters the cooling chamber 51, so that the mold is cooled from the inside, so that the bottom of the mold is cooled more evenly and easier to demold. The bottom end of the connecting pipe 52 passes through and is fixedly connected to the piston column 53, the internal piston of the piston column 53 is connected to the piston plate 54, the piston plate 54 and the piston column 53 are filled with coolant, the bottom of the piston column 53 passes through and is connected to the piston with a piston rod 55, and the bottom surface of the piston rod 55 is fixedly connected to the inner side of the connecting base 1.A telescopic column 218 is fixedly connected to the inner side of the connecting seat 1, and a telescopic rod 219 is penetrated and slidably connected to the inner side of the telescopic column 218. After the upper mold base 3 rises a certain distance, the inclined surface of the hinge block 215 will contact the contact rod 210, so that the contact rod 210 pushes the triangular block 25 to shrink and no longer fits into the slot 27. At this time, the compressed spring three 220 will instantly lift the lower mold base 21 through the telescopic rod 219, and when the lower mold base 21 is lifted, it will hit the inner side of the stopper 4 and produce a strong vibration. The spring three 220 is fixedly connected between the telescopic rod 219 and the inner side of the telescopic column 218. The casting equipment is started, so that the upper mold base 3 applies pressure downward to the lower mold base 21, and the lower mold base 21 is embedded in the connecting seat 1, and the lower mold base 21 will push the telescopic rod 219 to insert into the telescopic column 218, and the spring three 220 will be compressed.

[0023] Based on the above embodiment, the connecting seat 1 and the upper mold seat 3 are connected to the casting equipment, and the casting equipment is started, so that the upper mold seat 3 applies pressure downward to the lower mold seat 21, and the lower mold seat 21 is embedded in the connecting seat 1, and the lower mold seat 21 will push the telescopic rod 219 to insert into the telescopic column 218, and the spring three 220 will be compressed. When the lower mold seat 21 is embedded in the connecting seat 1, the insertion rod 22 will be inserted into the connecting seat 1 at the same time, and the inclined surface of the triangular block 25 will contact the inner side of the connecting seat 1 and shrink into the square hole 23, and the spring one 26 will be compressed. After the lower mold seat 21 is fully engaged with the connecting seat 1, the triangular block 25 is just aligned with the card slot 27, and the compressed spring one 26 will push the triangular block 25 into the card slot 27, and when the upper mold seat 3 moves downward, the hinge block 215 will contact the inclined surface of the contact rod 210 and shrink into the shrinkage groove 213, and the torsion spring 2 17 is compressed, and when the hinge block 215 moves to the bottom of the abutment rod 210, the compressed torsion spring 217 will push out the hinge block 215. When the circuit breaker housing model is cast, the upper mold base 3 is pulled up by the casting equipment. When the upper mold base 3 is just rising, the lower mold base 21 is stuck in the card slot 27 because the triangular block 25 is stuck in the card slot 27, so that the lower mold base 21 cannot be raised together with the upper mold base 3. However, after the upper mold base 3 is raised for a distance, the hinge block 215 The inclined surface will contact the contact rod 210, so that the contact rod 210 pushes the triangular block 25 to shrink and no longer fit into the card slot 27. At this time, the compressed spring three 220 will instantly lift the lower mold base 21 through the telescopic rod 219. When the lower mold base 21 is lifted up, it will hit the inner side of the stopper 4 and generate strong vibration. The impact force during lifting will cause the cast circuit breaker model and the lower mold base 21 to loosen, making it easier to demould.

[0024] When the lower die base 21 is pushed downward by the upper die base 3, the lower die base 21 will drive the connecting tube 52 and the piston column 53 to move downward together, so that the piston rod 55 pushes the piston plate 54 relatively, and then the coolant in the piston column 53 enters the cooling chamber 51, so that the mold is cooled from the inside, the bottom of the mold is cooled more evenly, and it is easier to demold.

[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
