Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold closing and locking mechanism. Background Technology

[0002] In order to improve the processing accuracy of products, the current casting molds are locked by a mold-locking structure after the upper mold base and the lower mold base are closed. This ensures the stability of the mold closing between the upper mold base and the lower mold base, thereby ensuring the processing accuracy of the products.

[0003] A search revealed a mold for quick locking of front and rear molds, disclosed in publication number "CN107696349A". The mold includes a front mold, a rear mold, and a locking mechanism for locking the front and rear molds. The locking mechanism includes a locking plate rotatably connected to the front mold and locking both the front and rear molds after rotation. The locking plate has a closed hole on its rotating part and an open screw hole on its locking part. Locking is achieved by rotating the locking plate counterclockwise to engage the screw; unlocking is achieved by rotating the screw clockwise. This design is convenient, time-saving, and reduces labor and cost.

[0004] The above-mentioned mold is mainly locked by setting locking plates at the corners. During the use of this locking structure, we found that it only locks one corner of the mold and does not lock the other corners, which affects the locking effect. During the casting process, the other corners of the mold are easily compressed and deformed. To solve the above technical problems, we designed a mold closing and locking mechanism.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-4 The mold closing and locking mechanism shown includes a lower mold base 1 and an upper mold base 2. The lower mold base 1 has connecting grooves 3 on both sides of its top end. The upper mold base 2 has connecting blocks 4 fixed on both sides of its bottom end. The connecting blocks 4 are embedded in the connecting grooves 3. The front of the connecting blocks 4 is fixedly provided with a locking module 17. The locking module 17 has multiple through locking holes 18 equidistantly opened inside. The center of the front of the lower mold base 1 is fixedly provided with a fixing box 5. Multiple retractable locking rods 10 are equidistantly arranged on both sides of the fixing box 5. The multiple locking rods 10 are inserted into the corresponding locking holes 18.

[0020] Specifically, the retractable locking rods 10 on both sides of the fixed box 5 are inserted into the locking holes 18 on the surface of the locking module 17, so that the connecting block 4 can be fixed inside the connecting groove 3, thereby realizing the locking between the upper mold base 2 and the lower mold base 1.

[0021] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a mold closing and locking mechanism. Two vertically distributed limiting rods 11 are fixedly installed inside the fixed box 5. Two sliding plates 12 are slidably connected to the surfaces of the two limiting rods 11. The sides of the two sliding plates 12 are fixedly connected to the ends of the corresponding mold locking rods 10. The mold locking rods 10 are inserted and connected to the through holes opened on the surface of the fixed box 5.

[0022] Specifically, by setting the limiting rod 11, the movement direction of the two slide plates 12 can be limited, ensuring that the slide plates 12 can only slide on the surface of the limiting rod 11. By limiting the slide plates 12, the locking rod 10 can stably pass through the through hole and be inserted into the corresponding locking hole 18.

[0023] Two fixing bars 13 are fixedly provided on the other side of each of the two sliding plates 12. The two fixing bars 13 are arranged in parallel, and the bottom end of the top fixing bar 13 and the top end of the bottom fixing bar 13 are provided with toothed grooves 15. The side wall of the fixing box 5 is rotatably connected to the connecting shaft, and a gear 14 is fixedly installed at the end of the connecting shaft. The gear 14 meshes with the two toothed grooves 15.

[0024] Specifically, the top and bottom ends of the gear 14 engage with the toothed grooves 15 on the surface of the fixing bar 13, thereby enabling the two fixing bars 13 to move synchronously. The movement of the fixing bars 13 causes the two sliding plates 12 to slide synchronously on the surface of the limiting rod 11.

[0025] Both fixing strips 13 are fixedly installed with a stop block 16 at their ends. The size of the stop block 16 is larger than the size of the end face of the fixing strip 13.

[0026] Specifically, through the design of the stop 16, when the two slide plates 12 are moving in opposite directions, the maximum moving distance of the slide plate 12 can be controlled, while preventing the gear 14 from separating from the tooth groove 15.

[0027] The other side wall of the fixed box 5 is provided with a through groove 8 that communicates with the outside. A push block 9 is slidably connected inside the through groove 8. The side of the push block 9 is fixedly connected to the side of the corresponding slide plate 12.

[0028] An installation plate 6 is fixedly installed at the center of the front of the fixed box 5, and an electric hydraulic cylinder 7 is fixedly installed at the center of the installation plate 6. The telescopic end of the electric hydraulic cylinder 7 is fixedly connected to the side of the push block 9.

[0029] Specifically, the push block 9 is moved by the electric hydraulic cylinder 7, and the push block 9 drives the connected slide plate 12 to move. The two slide plates 12 are driven by the gear 14 and the fixed bar 13, so as to realize the synchronous movement of the two slide plates 12. The movement of the slide plates 12 drives the extension and retraction of the locking rod 10, so as to realize the insertion and separation of the locking rod 10 and the locking hole 18.

[0030] The working principle of this utility model is as follows: When the upper mold base 2 and the lower mold base 1 are closed, the connecting block 4 is embedded in the connecting groove 3. At this time, the electric hydraulic cylinder 7 is opened, and the push block 9 is moved by the electric hydraulic cylinder 7. The movement of the push block 9 drives the connected slide plate 12 to move. The two slide plates 12 are driven by the gear 14 and the fixing bar 13. When the connected slide plate 12 moves, it drives the fixed bar 13 connected to it to move. The movement of the fixed bar 13 drives the gear 14 to rotate. The rotation of the gear 14 drives the other fixed bar 13 to move in the opposite direction. The movement of the other fixed bar 13 pushes the other slide plate 12 to move synchronously. The movement of the slide plate 12 drives the connected locking rod 10 to move, so that the locking rod 10 moves out of the fixed box 5 and is inserted into the locking hole 18 opened on the surface of the corresponding locking module 17, so that the connecting block 4 can be fixed in the connecting groove 3, thus completing the locking between the lower mold base 1 and the upper mold base 2.
