Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a gear-driven ejection device for demolding a binding bowl pressing mold. Background Technology

[0002] Lacquer cups are widely used on container ships and are a core component for securing containers. Container ships differ significantly in shape and structure from general cargo ships; they are long and narrow, with a single deck, a flat upper deck, and large hatch openings, their width reaching 70%-80% of the ship's beam. Lacquer cups have lashing devices on the deck and hatch covers to secure the containers loaded on the deck. As a core component of the container deck lashing system, lasher cups often face demolding difficulties due to their deep cavity structure after pressing. Traditional demolding methods rely on manual hammering or hydraulic ejection, which suffer from high mold damage risks (approximately 30% mold deformation rate), uneven demolding force (resulting in a 15% burr rate), and low production efficiency (demolding time exceeding 20 seconds per cycle). With the increasing demand from the global shipping industry, the annual demand for lasher cups has exceeded 8 million units, making the development of efficient and stable demolding tooling a necessity for the industry. Based on our processing experience, we have designed this tooling specifically for the demolding process of the pressing molds for lasher cups. Utility Model Content

[0028] Figure 1 This is a schematic structural diagram of the gear-driven ejection device for demolding the binding bowl pressing mold, such as... Figure 1 As shown, and with reference Figures 2 to 5 This utility model embodiment provides a gear-driven ejection device for demolding a binding bowl pressing mold. The gear-driven ejection device for demolding a binding bowl pressing mold 100 includes a mold 100, a demolding component 200, and an operating component 300.

[0029] The mold 100 includes a punch 110, which has an ejector hole 120, a mounting cavity 170, and a demolding groove 150. The ejector hole 120 is located inside the punch 110, with its upper outlet located at the top of the punch 110. The mounting cavity 170 is located inside the punch 110 and communicates with the lower end of the ejector hole 120. The demolding groove 150 is provided on the mold 100, with one end communicating with one side of the mold 100 and the other end communicating with the mounting cavity 170.

[0030] The demolding assembly 200 includes a demolding rod 210 and a demolding bevel gear 220. The demolding rod 210 is slidably inserted into the lifting hole 120 and is a lead screw. The demolding bevel gear 220 is rotatably disposed in the mounting cavity 170, sleeved on the demolding rod 210, and threadedly connected to the demolding rod 210. The operating assembly 300 includes an operating rod 310 and an operating bevel gear 320. The operating rod 310 is rotatably inserted into the demolding groove 150, with its inner end inserted into the mounting cavity 170. The operating bevel gear 320 is fixedly sleeved on the operating rod 310 and connected to the demolding bevel gear 220 so that the demolding bevel gear 220 and the operating bevel gear 320 rotate synchronously.

[0031] Specifically, the initial state of the ejector rod 210 is entirely within the lifting hole 120, and the upper end of the ejector rod 210 is coplanar with the outer surface of the punch 110 to ensure the flatness of the workpiece surface during the molding process. Furthermore, the ejector rod 210 and the lifting hole 120 are splined, allowing the ejector rod 210 to slide vertically only within the lifting hole 120. Since the ejector rod 210 is threadedly engaged with the ejector bevel gear 220, they form a screw-nut mechanism, which drives the ejector rod 210 to move vertically when the ejector bevel gear 220 rotates, thereby completing the demolding of the workpiece on the punch 110. Furthermore, the rotation of the operating lever 310 drives the ejector bevel gear 220 to rotate via the operating bevel gear 320, thereby driving the ejector rod 210 to move vertically. The operation of the bevel gear 320 drives the demolding bevel gear 220 to rotate, which can change the transmission direction of the operating lever 310. This allows the demolding operation on the workpiece on the punch 110 to be achieved by simply rotating the operating lever 310, thereby greatly improving the demolding efficiency. This is beneficial for demolding operations in batch production, thus improving the workpiece processing efficiency.

[0032] During operation, when a workpiece needs to be demolded from the punch 110, the operator rotates the operating lever 310. The rotation of the operating lever 310 drives the operating bevel gear 320 to rotate. The operating bevel gear 320 then drives the demolding bevel gear 220 to rotate. Because the demolding bevel gear 220 and the demolding rod 210 are threadedly engaged, the demolding bevel gear 220 causes the demolding rod 210 to move upwards. The upward movement of the demolding rod 210 ejects the workpiece from the punch 110. When it is necessary to reset the demolding rod 210, rotating the operating lever 310 in the opposite direction will reset the demolding rod 210.

[0033] In this embodiment, the outer end of the operating lever 310 is provided with an internal hexagonal hole, which makes it convenient for the operator to rotate the operating lever 310 with an internal hexagonal wrench.

[0034] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the mounting cavity 170 includes a first mounting cavity 130 and a second mounting cavity 140, which are connected by a connecting groove 160. The first mounting cavity 130 is connected to the lifting hole 120. The second mounting cavity 140 is connected to the demolding groove 150, and the demolding bevel gear 220 is rotatably mounted in the first mounting cavity 130. The operating bevel gear 320 is rotatably mounted in the second mounting cavity 140. The operating assembly 300 also includes a transmission gear 330, which is rotatably disposed in the connecting groove 160, with its two ends meshing with the demolding bevel gear 220 and the operating bevel gear 320, respectively.

[0035] Specifically, the connection groove 160 provides stability for the transmission gear 330, and the transmission gear 330 enables the operating bevel gear 320 and the demolding bevel gear 220 to rotate synchronously, thereby improving transmission stability.

[0036] In some embodiments of this utility model, such as Figure 5 As shown, the transmission gear 330 includes a transmission shaft and two transmission bevel gears. The transmission shaft is rotatably mounted in the connecting groove 160, and the two transmission bevel gears are located in the first mounting cavity 130 and the second mounting cavity 140, respectively, and are fixedly disposed at both ends of the transmission shaft. The two transmission bevel gears mesh with the demolding bevel gear 220 and the operating bevel gear 320, respectively.

[0037] In this embodiment, there are two punches 110, which are symmetrically arranged vertically, and their mounting cavities 170 are interconnected. That is, two demolding bevel gears 220 are rotatably arranged within the first mounting cavity 130, each corresponding to one of the two demolding rods 210. The transmission bevel gears are designed to mesh with both demolding bevel gears 220 simultaneously, causing them to drive the two demolding rods 210 to move synchronously up and down, thereby further improving demolding efficiency.

[0038] Furthermore, there is only one demolding groove 150, one operating lever 310, and one operating bevel gear 320, so that one operating lever 310 can drive two demolding bevel gears 220 to rotate through the operating gear.

[0039] In this embodiment, the mold 100 is divided into upper and lower parts, which are detachably fixed together by a connection, thereby making the mounting cavity 170 a whole sealed. The upper and lower parts of the mold 100 facilitate the disassembly and assembly of the demolding bevel gear 220 and the operating bevel gear 320.

[0040] In this embodiment, the operating bevel gear 320, transmission gear 330, and demolding bevel gear 220 constitute a three-stage blow gear reduction ratio of 1:5, increasing the output torque by 4 times and overcoming demolding resistance exceeding 2000N. Furthermore, the ejector pin head integrates a hydraulic buffer piston, automatically releasing pressure upon contact with the mold 100 to avoid rigid impact. Furthermore, a guide groove is provided within the positioning ring to ensure that the coaxiality error of the ejector pin is <0.1mm.

[0041] In some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, a limiting ring 131 is provided in the first mounting cavity 130. The limiting ring 131 is fixedly installed in the first mounting cavity 130, and the lower end of the demolding rod 210 can be inserted into the limiting ring 131.

[0042] Specifically, the inner wall of the limiting ring 131 is threaded, and the limiting ring 131 is threadedly connected to the lower end of the demolding rod 210. The limiting ring 131 can position the demolding rod 210, thereby keeping the demolding rod 210 in its initial position.

[0043] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, a first bearing 132 is fixedly installed in the first mounting cavity 130, and a demolding bevel gear 220 is installed on the first bearing 132. A second bearing 141 is fixedly installed in the second mounting cavity 140, and an operating lever 310 is installed on the second bearing 141.

[0044] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
