Description

Technical Field

[0001] The utility model relates to the technical field of sandbox molds, in particular to a sandbox mold supporting mechanism. Background Art

[0002] When producing mechanical parts, a sand box is used as a mold. Sand is loaded into the sand box, leaving space for the model, and then liquid metal is injected into the sand box into the model. The required mechanical parts can be obtained by cooling. The sand box can prevent the molding sand from moving or deforming during the casting process. When the molding sand is filled into the sand box and compacted, the four walls and bottom of the sand box provide a stable support to ensure that the molding sand remains in the correct position and improve the quality of the parts.

[0003] When the molding sand is loaded into the sandbox, the molding sand will accumulate in the sandbox instead of being spread out directly. At this time, the staff needs to shake the sandbox so that the molding sand can be spread out in the sandbox. However, in actual operation, as the molding sand in the sandbox continues to accumulate in the sandbox, the weight of the sandbox will increase. At this time, it is time-consuming and laborious for the staff to shake the sandbox, and the molding sand cannot be laid tightly inside the sandbox, which will affect the use effect. Therefore, a sandbox mold support mechanism is proposed to solve the above problem. Utility Model Content

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] Reference Figures 1-4The utility model provides a technical solution: a sandbox mold support mechanism, including a base 1 and a support assembly 3, and a support column 2 is fixedly installed on the upper surface of the base 1, the support assembly 3 includes a rectangular plate 31, the rectangular plate 31 is fixedly installed on the outer surface of the support column 2, and a first spring 311 is stably installed on the upper surface of the rectangular plate 31 at a position symmetrical to the center of the rectangular plate 31, the receiving plate 32 is fixedly connected to the first spring 311, and a second spring 321 is also fixedly installed on the upper surface of the receiving plate 32, and a sandbox body 322 is installed above the second spring 321, a baffle 33 is installed on the upper surface of the base 1, and the same baffle 33 is installed on the base 1 at a position symmetrical to the baffle 33, for shaking the sandbox body 322.

[0030] In a preferred embodiment, a mounting plate 4 is fixedly installed at one end of the second spring 321, and the mounting plate 4 is fixedly connected to the bottom of the sandbox body 322. In order to control the shaking of the sandbox body 322, a mounting plate 4 is installed at one end of the second spring 321, and the sandbox body 322 is installed on the mounting plate 4. Through the instability of the second spring 321, the sandbox body 322 can be shaken, thereby shaking the molding sand inside the sandbox body 322, which not only spreads the molding sand, but also makes the molding sand compactly stacked.

[0031] In a preferred embodiment, a through hole 5 is provided on the upper surface of the receiving plate 32, the second spring 321 is arranged above the through hole 5, and a limiting column 6 is installed on the top of the support column 2. As the weight of the sandbox body 322 continues to increase, the sandbox body 322 will continue to move downward. At this time, the second spring 321 will be sleeved on the outside of the limiting column 6, so as to control the sandbox body 322 from shaking at will, avoid deformation of the space inside the molding sand, and ensure that the device can be used normally.

[0032] In a preferred embodiment, a connecting rod 7 is slidably installed inside the baffle 33, and an impact plate 8 is fixedly installed at one end of the connecting rod 7. The impact plate 8 corresponds to the position of the sand box body 322. A third spring 9 is installed on the outer surface of the baffle 33, and one end of the third spring 9 is fixedly connected to the pull rod 10, and the pull rod 10 is stably connected to the connecting rod 7. When the sand box body 322 moves downward and the second spring 321 is sleeved on the outside of the limit column 6, molding sand will continue to be added to the inside of the sand box body 322. In order to allow the molding sand to be tightly filled in the inside of the sand box body 322, the pull rod 10 will be pulled to move, and then quickly released after pulling the pull rod 10. At this time, under the action of the third spring 9, the impact plate 8 will be hit against the outside of the sand box body 322, thereby shaking the molding sand and making it more compact.

[0033] In order to facilitate the addition of metal liquid into the reserved space inside the sandbox body 322, a top cover 11 is provided on the top of the sandbox body 322, and a feed bin 12 is provided on the top of the top cover 11 for adding metal liquid into the sandbox body 322.

[0034] Since the interior of the sand box body 322 is filled with molding sand, space for pouring parts will be reserved so that the metal liquid can be poured into the space later. In order to stably install the top cover 11 on the top of the sand box body 322 and avoid causing the sand box body 322 to shake, a limiting mechanism 13 is installed on the base 1. The limiting mechanism 13 includes a vertical plate 131, a moving block 132 and a sliding groove 133. The vertical plate 131 is fixedly installed on the outer surface of the base 1, and a sliding groove 133 is opened on the inner side of the vertical plate 131. The outer side of the top cover 11 is fixedly installed with a moving block 132. The internal sliding arrangement of the moving block 132 and the sliding groove 133 is used to limit the top cover 11.

[0035] During actual use, in order to ensure that the top cover 11 is aligned with the sandbox body 322 and to avoid controlling the sandbox body 322 to shake again, when installing the top cover 11, the moving block 132 is moved into the sliding groove 133. Since the moving block 132 and the top cover 11 are integrated, limiting the moving block 132 is the same as limiting the top cover 11. At this time, the top cover 11 can be completely aligned with the top position of the sandbox body 322. The top cover 11 can be directly moved down to install it on the top of the sandbox body 322. Then, the metal liquid is added from the inside of the feed bin 12 to the space reserved inside the sandbox body 322. Through the set shape, parts that meet the needs of use can be obtained.

[0036] Specifically, the working process or working principle of a sandbox mold support mechanism is: when the molding sand is loaded into the sandbox, the molding sand will accumulate in the sandbox and will not be spread directly. At this time, the staff is required to shake the sandbox so that the molding sand can be spread in the sandbox. However, in actual operation, as the molding sand in the sandbox continues to pile up in the sandbox, the weight of the sandbox will increase. At this time, it is time-consuming and laborious for the staff to shake the sandbox, and the molding sand cannot be laid tightly inside the sandbox, which will affect the use effect. Therefore, this device is designed to solve this problem.

[0037] The present invention can support the sand box body 322 while shaking the sand box body 322, so that the device can hit the baffle 33, so that the molding sand inside the sand box body 322 is spread out, and as the molding sand continues to increase, the molding sand can be tightly filled in the sand box body 322 to facilitate the production of parts. The specific operation is to fill the molding sand into the sand box body 322 and at the same time push the sand box body 322 to shake. A second spring 321 is installed at the bottom of the sand box body 322. When molding sand is loaded into the sand box body 322, it will drive the sand box body 322 to shake, and the accumulated molding sand will be spread out in the sand box body 322, at the bottom of the sand box body 322, and the accumulated molding sand will be compacted in the sand box body 322 in a compact state, so that the parts can be cast and processed, and the parts can be stably produced under the protection of the molding sand.

[0038] When the sandbox body 322 is shaken, it will move left and right and easily collide with the baffle 33, thereby improving the compactness of the molding sand inside the sandbox body 322 to meet the needs of use.

[0039] As the weight of the sandbox body 322 continues to increase, the sandbox body 322 will move downward. At this time, the second spring 321 will be controlled to move downward and be sleeved on the outside of the limiting column 6. The outer surface of the limiting column 6 slides with the inner ring of the second spring 321, so that the heavier the sandbox body 322 is, the more stable the sandbox body 322 is. After the second spring 321 is sleeved on the outside of the limiting column 6, the sandbox body 322 cannot be controlled to shake left and right. At this time, the molding sand needs to be vibrated to make it compact inside the sandbox body 322. You only need to pull the pull rod 10, then release the pull rod 10 and under the action of the third spring 9, make the impact plate 8 hit the outside of the sandbox body 322, so that the molding sand falls inside the sandbox body 322, making the gaps between the molding sand smaller, more compact, and easy to use.

[0040] After the hopper 322 is fully loaded, the top cover 11 is moved downwards to allow the top cover 11 to be installed on the top of the hopper 322.
