Description

Technical Field

[0001] The utility model relates to the technical field of mold vacuum exhaust blocks, in particular to a mold vacuum exhaust block which can be quickly cleaned. Background Art

[0002] As various industries have higher requirements for the porosity of die-casting parts, vacuum die-casting technology has become a common method to improve the quality of die-casting. Since the vacuum channel will be blocked by residues, it needs to be cleaned regularly, and the length of time for cleaning will affect production efficiency. Conventional exhaust blocks are integral structures, and the exhaust channel has a bending structure, so cleaning is time-consuming. If it cannot be cleaned on the press, the mold needs to be removed from the machine and the exhaust block needs to be disassembled for cleaning, which is time-consuming and labor-intensive, affecting the continuous use of the mold. Utility Model Content

[0003] The utility model provides a mold vacuum exhaust block which can be quickly cleaned and has a simple structure, and can solve the problem that the vacuum channel of the existing mold vacuum exhaust block is blocked by residues and is time-consuming and laborious to clean.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold vacuum exhaust block that can be quickly cleaned, comprising an upper exhaust block and a lower exhaust block, one end of the lower exhaust block is detachably provided with an end insert, the middle part of the end insert is provided with a vacuum outlet, the lower exhaust block and the end insert are spliced ​​to form a vacuum inlet, the vacuum inlet is connected with the vacuum outlet, a cooling water path is provided inside the lower exhaust block, both ends of the cooling water path extend to the end surface of the lower exhaust block facing the end insert, a protruding platform corresponding to the cooling water path is provided at the end of the lower exhaust block, the protruding platform is embedded in the limiting groove on the inner side of the end insert, a cooling water pipe connected to the protruding platform is passed through the end insert, and the end insert can be disassembled when the vacuum inlet and the vacuum outlet need to be cleaned by setting the end insert, thereby greatly improving the cleaning efficiency and not affecting the normal use of the cooling water path inside the exhaust block.

[0005] Preferably, screw through holes are provided at both ends of the end insert, and fixing screws connected to the lower exhaust block are passed through the screw through holes, so that the end insert can be firmly and quickly installed and removed by the fixing screws.

[0006] Preferably, the protruding platform is a square boss or a circular boss, and the shape of the limiting groove matches the protruding platform, which can ensure the guide limit between the end insert and the lower exhaust block.

[0007] Preferably, exhaust ribs are evenly distributed on the upper side of the lower exhaust block, and the vacuum inlet is arranged at one end of the exhaust ribs, which can effectively perform the vacuum exhaust function.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] By setting the end inserts, they can be removed when the vacuum inlet and vacuum outlet need to be cleaned, which greatly improves the cleaning efficiency and does not affect the normal use of the cooling water channel inside the exhaust block. In actual use, it can save at least 2 hours for small exhaust blocks and save 1 day for large exhaust blocks that originally need to be taken off the machine for cleaning. At the same time, considering the need to reheat the mold and the cold parts generated when the mold is taken off the machine and waits for a long time, this structure greatly reduces the die-casting cost.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] The utility model aims to solve the problem that the vacuum channel of the existing mold vacuum exhaust block is blocked by residues and is time-consuming and laborious to clean. Figure 1-5As shown, the following technical scheme is provided: a mold vacuum exhaust block that can be quickly cleaned, comprising an upper exhaust block 1 and a lower exhaust block 2, one end of the lower exhaust block 2 is detachably provided with an end insert 3, the middle part of the end insert 3 is provided with a vacuum outlet 9, the lower exhaust block 2 and the end insert 3 are spliced ​​to form a vacuum inlet 7, the vacuum inlet 7 is connected with the vacuum outlet 9, a cooling water path 8 is provided inside the lower exhaust block 2, both ends of the cooling water path 8 extend to the end surface of the lower exhaust block 2 facing the end insert 3, the end of the lower exhaust block 2 is provided with a protruding platform 4 corresponding to the cooling water path 8, the protruding platform 4 is embedded in the limiting groove 10 on the inner side of the end insert 3, the end insert 3 is provided with a cooling water pipe 5 connected to the protruding platform 4, and the end insert 3 can be disassembled when the vacuum inlet 7 and the vacuum outlet 9 need to be cleaned by setting the end insert 3, which greatly improves the cleaning efficiency and does not affect the normal use of the cooling water path 8 inside the exhaust block.

[0019] Specifically, the upper side of the lower exhaust block 2 is evenly distributed with exhaust ribs 12, and the vacuum inlet 7 is arranged at one end of the exhaust ribs 12, which can effectively perform the vacuum exhaust function. The upper exhaust block 1 and the lower exhaust block 2 are placed in a stacked manner when in use, and the gap between the upper exhaust block 1 and the lower exhaust block 2 is used for vacuuming. The vacuum outlet 9 is used to connect to the vacuum pump, and the air can be evacuated from the gap between the upper exhaust block 1 and the lower exhaust block 2 through the vacuum inlet 7. Since the vacuum inlet 7 is composed of the end insert 3 and the lower exhaust block 2, when the end insert 3 is removed, the vacuum inlet 7 is split for easy cleaning, and when the end insert 3 is removed, the vacuum outlet 9 can be cleaned with anything through it, which is very convenient.

[0020] In this embodiment, if Figure 3-4 As shown, screw holes 11 are provided at both ends of the end insert 3, and fixing screws 6 connected to the lower exhaust block 2 are passed through the screw holes 11. The fixing screws 6 can be used to achieve firm and fast installation and disassembly of the end insert 3.
