[0026] The mould of the embodiment is composed of upper die holder 1 and lower die holder 2, and the lower die holder 2 is internally provided with a specific cavity 203 for forming the shape of a required product. A plurality of demolding ejector pins 204 are arranged in the cavity 203, and the ejector pins 204 are arranged in a character at the bottom of the cavity 203 to assist demolding. The design of the plurality of demolding ejector pins 204 and pneumatic driving significantly improves the speed and efficiency of demolding and reduces the need for manual intervention. The pneumatic driving assembly is used to replace manual operation, which reduces the risk of injury to operators and improves operational safety. The first top block 311 and the demolding ejector pin 204 are in a lever structure, and the demolding ejector pin 204 is lifted by the linkage rod 310 to perform demolding work after the first top block 311 is pressed down by the push rod 309.
[0027] The demolding mechanism 3 includes a mounting seat 301, a driving member arranged on the mounting seat 301, a connecting member, and a gear member. The connecting member includes a second top block 205 and an oscillating arm 306 connected with the gear member. The second top block 205 is arranged in the cavity 203. The oscillating arm 306 is provided with a connecting rod 307 for connecting the second top block 205. The driving member includes a first air cylinder 303 and two second air cylinders 308. The first air cylinder 303 is connected with the gear member. The second air cylinders 308 are symmetrically arranged on the mounting seat 301. The second air cylinders 308 are provided with push rods 309. The push rods 309 are connected with the first top block 311.
[0028] The embodiment uses double demolding mechanisms 3, which are symmetrically arranged on both sides of the mould. The demolding mechanism 3 includes a plurality of components, mainly including a mounting seat 301, a driving member (such as an air cylinder), a connecting member, and a gear member. The air cylinder is used to drive the linear movement of the gear 302, which is connected with the transmission gear 304 and the oscillating gear 305 to provide power for the demolding ejector pin 204. The second top block 205 is located in the cavity 203 and connected with the driving air cylinder through the oscillating arm 306. The oscillating arm 306 is provided with a connecting rod 307. The oscillating arm 306 is connected with the second top block 205 through the connecting rod 307. The second top block 205 and the demolding ejector pin 204 are synchronized to perform demolding, which significantly improves the speed and efficiency of demolding.
[0029] Further, the connecting member includes a linear moving gear 302, a transmission gear 304 and a swing gear 305, the linear moving gear 302 is connected with the first cylinder 303, the transmission gear 304 is engaged with the swing gear 305, and the swing gear 305 is connected with a swing arm 306.
[0030] The linear moving gear 302 is connected with the first cylinder 303. The pneumatic drive of the cylinder can make the linear moving gear 302 move quickly in the vertical direction (up and down direction). When the cylinder piston moves downward, the linear moving gear 302 moves downward correspondingly, and vice versa.
[0031] Further, the number of the transmission gear 304 and the swing gear 305 is 2, the transmission gears 304 on both sides of the linear moving gear 302 are engaged, and the linear moving gear 302 moves up and down through the first cylinder 303.
[0032] The linear moving gear 302 is provided with a transmission gear 304 on each side. Since the transmission gears 304 are engaged, the linear moving gear 302 can drive the two transmission gears 304 to rotate correspondingly while moving. Through appropriate gear ratio design, the rotation speed of the transmission gears 304 can be effectively matched with the moving speed of the linear moving gear 302.
[0033] The transmission gears 304 and the swing gears 305 are engaged, so that the rotation of the transmission gears 304 directly drives the swing gears 305 to rotate. The connecting arm (such as the swing arm 306) of the swing gear 305 can produce swing movement, which is used for motion transmission to the swing arm 306. Through the overall design of the above mechanism, the linear motion of the cylinder can be effectively converted into the swing action of the swing arm 306. The movement of the swing arm 306 can be coordinated with the movement of other components, wherein the swing arm 306 is connected with the second top block 205 through the connecting rod 307, when the connecting rod 307 moves along the guide groove 202, the second top block 205 moves upward in the cavity 203, thereby achieving rapid demolding.
[0034] Further, a plurality of ejector pins 101 are arranged between the upper die seat 1 and the lower die seat 2, the upper die seat 1 is provided with a core 102 matched with the cavity 203, both sides of the lower die seat 2 are provided with two guide grooves 202, the guide grooves 202 are arc-shaped, the connecting rod 307 is fixedly connected with the swing arm 306, and the connecting rod 307 is arranged in the guide groove 202.
[0035] The upper die holder 1 and the lower die holder 2 constitute the frame of the entire mold, and the cavity 203 and the core 102 are used to form the shape of the required product. In the working state, the upper die holder 1 and the lower die holder 2 are kept in close contact through appropriate fastening mechanisms to ensure the sealing of the cavity 203.
[0036] The arc-shaped guide grooves 202 on both sides of the lower die holder 2 are designed to guide the movement trajectory of the connecting rod 307. In the movement of the swing arm 306, the connecting rod 307 can move along the predetermined trajectory, thereby ensuring the consistency and accuracy of the overall movement. The connecting rod 307 is fixedly connected with the swing arm 306, and when the swing arm 306 is driven to move by the cylinder or other power device, the connecting rod 307 moves together with the swing arm 306. The connecting rod 307 is arranged in the guide groove 202, and the movement of the connecting rod 307 is limited by the guide groove 202, thereby maintaining the stability of the movement and the accuracy of the direction, and pushing the second ejector rod 205 to move up and down appropriately.
[0037] Further, the lower die holder 2 is also provided with a cooling mechanism 4, which is arranged at the bottom of the cavity 203 and includes a heat dissipation seat 402 and a cooling assembly 403. The heat dissipation seat 402 is connected with the cavity 203.
[0038] The heat dissipation seat 402 is connected with the cavity 203 and is mainly used for conducting the heat generated inside the cavity 203 to the cooling assembly 403. Since a large amount of heat is generated during the molding process, the heat dissipation seat 402 can effectively conduct the heat to the cooling mechanism 4, thereby avoiding the influence of high temperature on the quality of the finished product. The cooling assembly 403 is provided with cooling pipes 406 arranged in a line, which can ensure that the cooling liquid is uniformly distributed inside the cavity 203. The design of the cooling pipes 406 can effectively enhance the heat exchange between the cooling pipes 406 and the cavity 203, and rapidly absorb the heat in the cavity 203.
[0039] Further, the cooling assembly 403 includes the cooling pipes 406, a control valve 405 connected with the cooling pipes 406, and a conveying pipe 404. The cooling pipes 406 are arranged in a line in the cavity 203, one side of the lower die holder 2 is provided with a cooling liquid input interface 401, and the cooling liquid input interface 401 is connected with the conveying pipe 404.
[0040] The control valve 405 connected with the cooling pipes 406 is used to adjust the flow and flow rate of the cooling liquid. When the temperature of the mold is too high, the control valve 405 can be opened to allow the cooling liquid to flow into the cooling pipes 406, thereby reducing the temperature of the mold; on the contrary, if the temperature is appropriate, the control valve 405 can be closed to save energy. During the cooling process, the cooling liquid absorbs heat and is transported to the external cooling system for heat dissipation, or returns to the cooling liquid storage device, forming a circulating system to ensure continuous cooling.
[0041] Further, the second top block 205 and the number of swing arms 306 are both two, and the second top block 205 is symmetrically arranged on both sides of the cavity 203.
[0042] The swing arm 306 is connected with the second top block 205 and is responsible for driving the movement of the top block. When the swing arm 306 moves, the connected second top block 205 will move along a certain trajectory, thereby pushing the finished product in the cavity 203 to move outward. Since the number of second top blocks 205 is two and symmetrically arranged, synchronous movement can be achieved when the mold is opened and closed. The action of the swing arm 306 promotes the simultaneous movement of the two top blocks to ensure the stability and reliability of the demolding process.
[0043] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
