Description

Technical Field

[0001] This utility model relates to the field of pipe casting technology, and in particular to a lost foam casting mold for pipe casting. Background Technology

[0002] Lost foam casting, also known as solid casting, is a new type of casting method that involves bonding and assembling paraffin or foam models similar in size and shape to the casting into a model cluster, coating them with refractory paint and drying them, then embedding them in dry quartz sand and vibrating them to create the model. Under negative pressure, the casting is poured in, causing the model to vaporize, the liquid metal to occupy the model's position, and after solidification and cooling, the casting is formed.

[0003] Existing lost foam casting molds, such as the lost foam casting mold for pipe fittings disclosed in application number CN202223145182.0, belong to the field of mold processing technology. They include an upper mold and a lower mold. The lower mold has two opposing semi-tubular blocks, and the upper mold has grooves corresponding to the semi-tubular blocks. The semi-tubular blocks and grooves cooperate to form cavities for semi-tubular lost foam molding. Each semi-tubular block consists of a fixed block fixedly installed on the lower mold and a freely movable block. The fixed block includes a front end block and a rear end block located at both ends of the semi-tubular block. However, in the above technology, the mold bodies of the upper and lower molds are significantly different, which can easily cause product damage during demolding after casting. Therefore, this utility model proposes a lost foam casting mold for pipe fittings to solve the problems existing in the prior art. Utility Model Content

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-4 As shown, this embodiment proposes a lost foam casting mold for pipe casting, including a slide bottom sealing assembly 1 and a cap feeding mechanism 3. The upper side of the slide bottom sealing assembly 1 is provided with a bolted mating part 2, and the cap feeding mechanism 3 is bolted to the upper ends of the mating part 2.

[0021] The sealing and feeding mechanism 3 includes a bolt connecting bar 301, a lifting frame 302, a crossbeam 303, a sleeve plate 304, a third hydraulic cylinder 305, a lifting frame 306, a lifting plate 307, a top arc cover 308, an inner liner tube 309, a bolt top plate 3010, and a plug 3011. The bolt connecting bar 301 is located above both ends of the mating component 2. Above the bolt connecting bar 301 is the lifting frame 302, and above the lifting frame 302 is a crossbeam 303. The inner side of the crossbeam 303 is provided with... There is a sleeve plate 304, and a lifting frame 306 connected to the output end of the third oil cylinder 305 is provided below the sleeve plate 304. A lifting plate 307 connected by bolts is provided below the lifting frame 306. A top arc cover 308 is provided below the middle part of the lifting plate 307. An inner liner tube 309 is provided below the middle part of the top arc cover 308. A bolt top piece 3010 connected by bolts is provided above the middle part of the top arc cover 308. Plugs 3011 are provided below both ends of the bolt top piece 3010.

[0022] The top arc cover 308 has an arc-shaped protrusion structure, and the central axis of the lifting plate 307, the top arc cover 308, and the inner liner tube 309 are on the same straight line.

[0023] In this embodiment, the third oil cylinder 305 on the crossbeam 303 then outputs power to drive the output end to run, so that the lifting frame 306 and the lifting plate 307 cooperate with the top arc cover 308 to close the mold body 205. After the raw material is poured in, the bolt top plate 3010 and the plug 3011 close the lifting plate 307 to achieve the closing effect and realize the casting processing effect.

[0024] The sliding base sealing assembly 1 includes a pad 101, a support plate 102, a bolt support 103, a sliding base 104, a transverse partition 105, a first hydraulic cylinder 106, a bottom arc cover 107, and a bottom insert cover 108. The support plate 102 is provided on the top side of the pad 101, and bolt supports 103 for bolt connection are provided above the perimeter of the support plate 102. The sliding base 104 is provided above the bolt supports 103.

[0025] In this embodiment, when in use, the pad 101 is used in conjunction with the support plate 102 to place the equipment at the processing location, so that the bolt support 103 and the sliding base 104 cooperate to enable the various components to be effectively spliced ​​and installed.

[0026] A horizontal partition 105 is provided on the inner side of the bolt support 103, and a first hydraulic cylinder 106 is provided on the inner side of the horizontal partition 105. A bottom arc cover 107 is provided at the output end of the first hydraulic cylinder 106, and a bottom cover 108 is provided above the middle part of the bottom arc cover 107.

[0027] In this embodiment, the first hydraulic cylinder 106 on the diaphragm 105 is then used to output power to drive the output end to run, so that after the first hydraulic cylinder 106 outputs power and runs, the bottom arc cover 107 and the bottom insert cover 108 are aligned with the mold body 205.

[0028] The mating component 2 includes an outer frame 201, a second hydraulic cylinder 202, a telescopic frame 203, a bolt side plate 204, a mold body 205, a slide bar 206, a slot 207, and an insert block 208. The outer frame 201 is bolted to the outer side of the middle part of the bolt support 103. The second hydraulic cylinder 202 is provided on the outer side of the outer frame 201, and the telescopic frame 203 is provided at the output end of the second hydraulic cylinder 202. The bolt side plate 204 is provided at the inner end of the telescopic frame 203.

[0029] In this embodiment, when processing is required, the second hydraulic cylinder 202 on the outer frame 201 is used to output power to drive the output end to run, so that the telescopic frame 203 extends after the second hydraulic cylinder 202 outputs power.

[0030] The inner side of the bolt side plate 204 is provided with a bolt-connected mold body 205, and a slide bar 206 is provided below the mold body 205. Slots 207 are provided on the inner sides of both ends of the mold body 205, and insert blocks 208 are provided on the outer sides of both ends of the mold body 205.

[0031] In this embodiment, after the telescopic frame 203 extends, the bolt side plate 204 pushes the mold body 205 so that the two sets of mold bodies 205 slide through the slide bar 206, thereby enabling the slot 207 and the plug block 208 to be effectively inserted and engaged.

[0032] The working principle of the lost foam casting mold for pipe fittings is as follows: During use, the pad 101, in conjunction with the support plate 102, places the equipment at the processing location. This allows the bolt support 103 and the sliding base 104 to work together to effectively assemble the various components. When processing is required, the second hydraulic cylinder 202 on the outer frame 201 outputs power to drive the output end. This power from the second hydraulic cylinder 202 causes the telescopic frame 203 to extend. After the telescopic frame 203 extends, the bolt side plate 204 pushes the mold body 205, causing the two sets of mold bodies 205 to slide along the slide bar 206, thus opening the slot 20. 7 and the insert block 208 are effectively inserted and engaged. Then, the first hydraulic cylinder 106 on the transverse partition 105 outputs power to drive the output end to run. After the first hydraulic cylinder 106 outputs power, the bottom arc cover 107 and the insert bottom cover 108 are engaged with the mold body 205. Then, the third hydraulic cylinder 305 on the crossbeam 303 outputs power to drive the output end to run. This causes the lifting frame 306 and the lifting plate 307 to cooperate with the top arc cover 308 to close the mold body 205. After the raw material is poured, the bolt top plate 3010 and the plug 3011 close the lifting plate 307 to achieve the closing effect and realize the casting processing effect.
