Description

Technical Field

[0001] The utility model relates to the technical field of static pressure molding equipment, in particular to a dual-mode box-poking machine. Background Art

[0002] The static pressure molding production line is a device for batch production of castings. Generally, the sand mold in the sand box is compacted by contacts. As the sand box moves, the core is lowered and closed, the casting is poured and cooled, and the sand is removed and the casting is removed. In order to reduce the casting temperature to a specified temperature, the production line is usually equipped with a circulating cooling line. The sand box travels a certain distance on the cooling line before the sand is removed and the casting is removed. Due to the limited space for the circulating cooling line, castings with smaller cooling requirements can be cooled to the specified temperature after one circle on the circulating cooling line. However, castings with larger cooling requirements cannot be cooled to the specified cooling temperature after only one circle on the circulating cooling line. If the casting is cooled multiple times on the circulating cooling line, the normal batch production of the static pressure molding line will be affected, reducing the overall production efficiency.

[0017] The dual-mode box-poking machine described in this utility model is as follows: Figure 1-5 As shown, the apparatus comprises a stand 1, within which is mounted a horizontally arranged guide plate 2, which is provided with a sand mold inlet 3 and a casting outlet 4. The end of the guide plate 2, away from the casting outlet 4, is connected to a casing cooling circuit. A sand box cooling circuit is provided below the casing cooling circuit, and a plurality of casings 5 ​​are provided on the casing cooling circuit. The casings 5 ​​are boxes with upper and lower openings, and contain sand molds and castings. The sand molds and castings in the flasks can enter the casings 5 ​​at the sand mold inlet 3 and be transferred to the casing cooling circuit for cooling.

[0018] In order to ensure that the sand tires and castings on the bottom sand box cooling circulation line can be transferred to the sleeve box 5 and undergo additional circulation cooling, a sand box transfer mechanism and an upward-pushing box mechanism are installed on the stand 1 at the bottom of the sand tire inlet 3. The sand box transfer mechanism can grab the sand box on the sand box cooling circulation line and transfer it to the box-pushing mechanism, and under the action of the box-pushing mechanism, the sand tires and castings inside the sand box are pushed upward into the sleeve box 5 through the sand tire inlet 3.

[0019] A downward-pushing cleaning mechanism is mounted on the stand 1 above the casting outlet 4. Also mounted on this stand 1 is a casing transfer mechanism that drives the casing 5 back and forth between the casing cooling circuit, the sand mold inlet 3, and the casting outlet 4. When the casing 5 reaches the casting outlet 4, the sand mold and castings inside it fall out under the action of gravity, allowing them to be removed. The cleaning mechanism clears loose sand from the inner walls of the casing 5 and also functions as a prying mechanism to remove the castings, ensuring that the casing 5 at the casting outlet 4 is properly cleared and removed.

[0020] The sleeve box 5 and the sand box are not internal parts of the box-poking machine device, but are used as independent transport and loading equipment to realize the transfer, transportation and cooling of the sand mold and castings.

[0021] The above-mentioned dual-mode box-poking machine has two working modes of cooling cycle, sand dropping and part removal. When the cooling amplitude of the casting is required to be small, cooling is only performed on the sand box cooling circulation line. After the cooling meets the requirement, the sand box is separated from the walking trolley by the sand box transfer mechanism and sent to the position of the box-poking mechanism. The sand tire and casting inside the sand box are pushed upward into the casing 5 through the sand tire inlet 3 by the box-poking mechanism. After that, the casing 5 is moved by the casing transfer mechanism to the casting outlet 4. The sand tire and casting in the casing 5 fall under the action of gravity to complete the sand dropping and part removal operation.

[0022] When the cooling range of the casting is required to be large, the sand tires and castings on the sand box cooling circulation line need to be transferred to the casing cooling circulation line for further cooling. When the sand box transfer mechanism separates the sand box from the walking trolley and sends it to the position of the box-poking mechanism, the sand tires and castings inside the sand box are pushed upward into the casing 5 through the sand tire inlet 3 by the box-poking mechanism. The casing transfer mechanism moves the casing 5 to the casing cooling circulation line. After following the walking trolley to rotate one circle to meet the cooling requirement, the casing transfer mechanism removes the casing 5 from the casing cooling circulation line and transfers it to the casting outlet 4. The sand tires and castings in the casing 5 fall under the action of gravity to complete the sand removal and part removal operation. Compared with the traditional cooling operation, this cooling circulation mode adds a casing cooling cycle. Under the premise of not changing the size of the area occupied by the entire device, it effectively improves the cooling range and does not affect the normal production on the original sand box cooling circulation line, thereby improving the cooling production efficiency of the entire device.

[0023] like Figure 6 As shown, the flask transfer mechanism includes a first traveling frame 6, with flask clamping devices mounted on both sides thereof. These clamping devices can transfer the flask containing the mold and casting to the flask-moving mechanism at the bottom of the mold inlet 3. The first traveling frame 6 can move on a stand 1 below the guide plate 2. A motorized wheel or a horizontally retractable hydraulic cylinder can be mounted on the first traveling frame 6 to power the horizontal movement of the first traveling frame 6. The flask clamping device can be a conventional clamping manipulator or a clamping cylinder, capable of positioning and grasping the flask and moving synchronously with the first traveling frame 6.

[0024] like Figure 8 As shown, the casing transfer mechanism includes a second traveling frame 7, with casing clamping devices that cooperate with the casing 5 installed on both sides of the second traveling frame 7. The casing clamping devices can transfer the casing 5 with the sand tire and castings at the sand tire inlet 3 to the bottom of the cleaning mechanism at the casing cooling circulation line or the casting outlet 4. The second traveling frame 7 can move on the vertical frame 1 on the upper side of the guide plate 2. The second traveling frame 7 can be equipped with moving wheels with a motor or a hydraulic cylinder that can be horizontally extended and retracted as the power device for the horizontal movement of the second traveling frame 7. The casing clamping device can be an existing clamping manipulator or clamping cylinder, which can realize the positioning and grasping of the casing and move synchronously with the second traveling frame 7.

[0025] The box-poking mechanism includes a vertically arranged first telescopic cylinder 8, and a box-poking plate 9 is installed on the piston rod of the first telescopic cylinder 8. The box-poking plate 9 cooperates with the opening of the sand tire inlet 3 and the casing 5. The piston rod of the first telescopic cylinder 8 of the box-poking mechanism at the bottom of the sand tire inlet 3 is arranged upward, and the box-poking plate 9 is pushed upward, which can push the sand tire and casting in the sand box upward into the casing 5.

[0026] The cleaning mechanism includes a vertically arranged second telescopic cylinder 26, and a cleaning plate 27 is installed on the piston rod of the second telescopic cylinder 26. The cleaning plate 27 cooperates with the openings of the casting outlet 4 and the sleeve box 5. The piston rod of the second telescopic cylinder 26 of the cleaning mechanism above the casting outlet 4 is arranged downward, and the cleaning plate 27 is pushed downward to clean the floating sand on the inner wall of the sleeve box 5.

[0027] The biggest innovation of the dual-mode box-poking machine is that it can realize the function of poking out the sand mold and castings in the sand box and the function of poking out the sand mold and castings in the sleeve box 5, that is, "one machine with two uses".

[0028] Furthermore, in order to achieve a stable grip of the sand box, as Figure 7 As shown, the sand box clamping device includes a vertical cylinder 10 installed at the bottom of the first traveling frame 6, and a horizontally arranged first clamping plate 11 is hingedly installed on the piston rod of the vertical cylinder 10. The bottom of the first clamping plate 11 is provided with an inwardly extending support plate 12, which can be adapted to the protrusions on the side of the sand box.

[0029] When it is necessary to grab the sand box on the sand box cooling circulation line, the piston rod of the vertical moving cylinder 10 moves downward, allowing the supporting plate 12 to drop to the lower side of the protrusion on the side of the sand box. When the traveling trolley drives the sand box to the position of the sand box clamping device, the piston rod of the vertical moving cylinder 10 moves upward, driving the sand box to be vertically lifted and separated from the traveling trolley at the bottom. Then, it is driven by the first traveling frame 6 and sent to the position of the box poking mechanism, pushing the internal sand tire and casting upward into the sleeve box 5.

[0030] In order to achieve stable vertical lifting of the first clamping plate 11 , first guide rods 13 are provided at both ends of the length direction of the first clamping plate 11 , and a first guide sleeve 14 matching the first guide rods 13 is installed on the first traveling frame 6 .

[0031] In order to prevent the sand dropped during the transfer of the sand box from affecting the subsequent movement of the sand box, a first scraper plate 15 is installed at the bottom of the support plate 12. The first scraper plate 15 can clean the dropped sand during the reciprocating movement of the sand box transfer mechanism.

[0032] Furthermore, in order to achieve stable grasping and transfer of the casing 5, as shown in FIG. Figure 9 As shown, the casing clamping device includes a vertical plate 16 arranged at the bottom of the second traveling frame 7, and two rows of horizontally arranged clamping wheels 17 are provided on the inner side of the vertical plate 16. Figure 10As shown, both sides of the casing 5 are provided with second clamping plates 18 that cooperate with the clamping wheels 17, and guide ramps 19 are provided at both ends of the second clamping plates 18 in the longitudinal direction. The casing clamping device is located on the upper side of the casing cooling circulation line. When the traveling trolley drives the casing to move to the clamping device position, the guide ramps 19 preferentially cooperate with the clamping wheels 17, and during the movement of the traveling trolley, the casing 5 is lifted a certain distance. After the second clamping plates 18 are located within the clamping wheels 17, the casing 5 is separated from the traveling trolley.

[0033] In order to realize the positioning and clamping of the casing, a horizontally arranged positioning cylinder 20 is also installed on the vertical plate 16. Positioning holes 21 that cooperate with the piston rod of the positioning cylinder 20 are provided on both sides of the casing 5. When the piston rod of the positioning cylinder 20 enters the positioning hole 21, the casing clamping device can realize the stable grasping of the casing 5 and can follow the second traveling frame 7 to move to the sand tire inlet 3 or the casting outlet 4 to realize the subsequent sand tire loading or sand removal operations.

[0034] In order to prevent the sand dropped during the transfer of the casing 5 from affecting the subsequent movement of the casing 5, a second scraper plate 22 is installed at the bottom of the vertical plate 16. During the movement of the second traveling frame 7, the second scraper plate 22 can effectively clean the sand dropped on the guide plate 2.

[0035] Furthermore, in order to ensure the vertical stability of the cleaning mechanism when cleaning the casing 5, a mounting seat 23 is provided on the stand 1 at the cleaning position, the cylinder body of the second telescopic cylinder 26 is fixed on the mounting seat 23, and a vertically arranged second guide rod 24 is installed on the cleaning plate 27. A second guide sleeve 25 that cooperates with the second guide rod 24 is provided on the mounting seat 23. The cooperating second guide sleeve 25 and the second guide rod 24 can ensure the vertical stability of the cleaning plate 27, ensure that they can cooperate with the opening position of the casing 5, realize the cleaning function of the inner wall of the casing 5, and assist in the ejection of the sand tire and casting inside the casing 5.
