[0029] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 6 As shown, a hot pressing forming device for easy cleaning of a mold cavity comprises a fixing frame 1, a stamping device 2 mounted on the fixing frame 1, an upper die 3, a lower die 4, a flipping mechanism 5 and a cleaning device 6, wherein the upper die 3 is mounted at the output end of the stamping device 2, and the lower die 4 is provided with a flipping shaft 41, which is symmetrically arranged on both sides of the lower die 4 and hinged on the fixing frame 1;

[0031] The flip mechanism 5 includes a flip member 51 having a flip hole 511, and the flip shaft 41 passes through the flip hole 511 and is limitedly connected to the flip member 51, so that when the flip member 51 rotates, the flip shaft 41 can drive the lower mold 4 to rotate;

[0032] The cleaning device 6 is installed on a side of the fixing frame 1 away from the upper mold 3 , and an air outlet nozzle 61 is provided on a side of the cleaning device 6 facing the lower mold 4 . When the lower mold 4 rotates, the air outlet nozzle 61 outputs high-pressure gas to clean the surface of the lower mold 4 .

[0033] Specifically, in some embodiments, the fixing frame 1 is a structural frame for installing a stamping device 2, an upper die 3, a lower die 4, a flipping mechanism 5 and a cleaning device 6. The upper die 3 and the lower die 4 are the molds mainly responsible for molding in the hot pressing molding device. The upper die 3 and the lower die 4 are both provided with a mold cavity 43 for product molding. The mold cavity 43 located in the upper die 3 is the upper mold cavity, and the mold cavity 43 located in the lower die 4 is the lower mold cavity. The product raw material is heated and placed on the lower mold cavity of the lower die 4. The upper die 3 is pressed on the lower die 4 by the stamping device 2, so that the product is pressed and formed. The stamping device 2 A telescopic air cylinder or a telescopic hydraulic cylinder can be used to push the upper mold 3 and the lower mold 4 to be pressed together. The cleaning device 6 is a tool or device for cleaning the lower mold cavity. The cleaning device 6 is provided with an air outlet nozzle 61 on the side facing the lower mold 4. The cleaning device 6 is provided with a gas supply switch for starting gas supply. When the user observes that there is residue left on the surface of the lower mold 4, the flip mechanism 5 can be manually rotated to drive the lower mold 4 to rotate, and the gas supply switch can be turned on at the same time to make the high-pressure gas form a jet airflow. The air outlet nozzle 61 outputs high-pressure gas to spray and clean the surface residue of the lower mold 4, so that the residue is blown away.

[0034] The flipping mechanism 5 is a rotating component used for the user to manually rotate the flip shaft 41. The flipping member 51 is provided with a flipping hole 511 which is convenient for installation on the flip shaft 41. The flipping hole 511 is limit-connected with the flip shaft 41 so that when the flipping member 51 rotates, the flip shaft 41 can drive the lower mold 4 to rotate relative to the fixed frame 1. The user can use the flipping member 51 to rotate the mold cavity 43 of the lower mold 4 that needs to be cleaned to face the air outlet nozzle 61, and then start the air supply switch to spray and clean the mold cavity 43 of the lower mold 4.

[0035] like Figures 1 to 4 As shown, the fixing frame 1 is provided with a limiting groove 11 , and the flip member 51 is provided with a flip limiting block 52 . The flip limiting block 52 extends into the limiting groove 11 , so that the limiting groove 11 limits the rotation angle of the flip member 51 .

[0036] Specifically, in some embodiments, a limit groove 11 for limiting the rotation angle of the flip mechanism 5 is provided on one side of the hinged flip axis 41 of the fixed frame 1, and the limit groove 11 is arranged in a ring shape around the flip axis 41 on the fixed frame 1, and the flip limit block 52 is detachably installed on the flip member 51, and the flip limit block 52 is provided with a limit block for extending into the limit groove 11. When the flip member 51 rotates, it drives the flip limit block 52 to rotate in a circle around the flip axis 41, and the flip limit block 52 moves in the limit groove 11 until the end of the limit groove 11 limits the movement of the flip limit block 52. After the flip limit block 52 is limited, the mold cavity 43 of the lower mold 4 is just in the direction facing the air outlet nozzle 61, which is convenient for the user to directly rotate the lower mold 4 to the cleaning position without spending extra time to calibrate the rotation angle of the lower mold 4 to align with the air outlet nozzle 61. It is convenient and fast, and the efficiency is improved.

[0037] like Figures 1 to 6 As shown, the flip mechanism 5 further includes a flip handle 53 for facilitating manual flipping, and the flip handle 53 is installed on the flip member 51 .

[0038] Specifically, in some embodiments, the flip handle 53 is a fixed handle detachably mounted on the flip member 51 for facilitating the user's hand holding to rotate the flip member 51. A handle cover is provided at one end of the flip handle 53 for holding by hand. The surface of the handle cover is smooth and oval, which is convenient for multiple holding and rotation. The user can twist the flip member 51 through the flip handle 53 so that the flip member 51 can rotate in a circle around the flip axis 41, so as to easily rotate the lower mold 4 so that the mold cavity 43 is aligned with the air outlet nozzle 61, which is convenient and quick and improves efficiency.

[0039] like Figures 1 to 6 As shown, the upper mold 3 is provided with a positioning column 31, and the lower mold 4 is provided with a positioning cavity 42 for the positioning column 31 to extend into.

[0040] Specifically, in some embodiments, in order to improve the pressing accuracy between the upper mold 3 and the lower mold 4, the upper mold 3 is provided with a positioning column 31 for extending into the lower mold 4, and the lower mold 4 is provided with a positioning cavity 42 for the positioning column 31 to extend into. The contact edges of the positioning column 31 and the positioning cavity 42 are provided with large chamfers or rounded edges to facilitate easy insertion into the cavity. When the positioning column 31 extends into the positioning cavity 42, the rotation deviation of the lower mold 4 is corrected through the installation gap, so that the upper mold 3 and the lower mold 4 can be more accurately closed when the upper mold 3 and the lower mold 4 are closed, avoiding the lower mold 4 being in a deflected position when the upper mold 3 and the lower mold 4 are closed, resulting in the mold cavity 43 colliding and damaging the mold surface. The outer wall of the positioning column 31 and the cavity wall of the positioning cavity 42 can be subjected to local surface heat treatment to improve the surface hardness and make it more wear-resistant.

[0041] like Figures 1 to 4 and Figure 5 As shown, a bearing member 7 is installed between the tilting shaft 41 and the fixing frame 1 for facilitating rotation and bearing load.

[0042] Specifically, in some embodiments, the bearing member 7 is a mechanical element used to reduce rotational friction and support mechanical parts to transmit force and bear weight during relative motion. The bearing member 7 is installed between the flip shaft 41 and the fixed frame 1, which helps to improve the rotation smoothness of the flip shaft 41, reduce the friction of the flip shaft 41, and reduce the force required for the rotation of the lower mold 4. The bearing member 7 is installed at the position where the two sides of the lower mold 4 are connected to the fixed frame 1, which can improve the repeated rotation accuracy of the lower mold 4.

[0043] like Figures 1 to 4 As shown, the limiting groove 11 limits the rotation angle range of the flip member 51 to 0-180 degrees.

[0044] Specifically, in some embodiments, the lower mold 4 can be provided with the same mold cavity 43 on the upper and lower sides. When the lower mold 4 is flipped 180 degrees, the same mold cavity 43 can face the upper mold 3. The limiting groove 11 limits the rotation angle range of the flipping member 51 to 0-180 degrees, so that the mold cavity 43 can be directly rotated from the position of matching the upper mold 3 to the position facing the cleaning device 6 through the limitation of the limiting groove 11. The cleaned mold cavity 43 on the other side can be closed with the upper mold 3, and the steps of mold closing and cleaning can be performed at the same time, which simplifies the rotation step, reduces the calibration time, and rotates in one step, thereby improving the efficiency of mold closing, rotation and cleaning.

[0045] like Figures 1 to 4 As shown, the limiting grooves 11 are symmetrically arranged on both sides of the fixing frame 1 , and the flipping members 51 are symmetrically arranged on both sides of the lower mold 4 .

[0046] Specifically, in some embodiments, the limit groove 11 and the flip piece 51 are designed to be symmetrically arranged. When the lower mold 4 rotates, the limit grooves 11 on both sides simultaneously limit the rotation angle of the flip piece 51. Compared with the force on the flip piece 51 on one side, it is more helpful to maintain the force balance when the lower mold 4 rotates. The long-term repeated use of the flip mechanism 5 to flip the lower mold 4 has little effect on the deformation and displacement of the flip shaft 41, which is beneficial to the guarantee of the flipping accuracy and the mold closing accuracy, improves the force balance of the lower mold 4, improves the accuracy of the mold closing, improves the quality of the molded product, and improves the processing efficiency.

[0047] like Figure 3 and Figure 4 As shown, the flip hole 511 is provided with an outer keyway, the flip shaft 41 is provided with an inner keyway, and the flip hole 511 and the flip shaft 41 are connected via a key.

[0048] Specifically, in some embodiments, the limiting connection between the flip hole 511 and the flip axis 41 is achieved by a key connection using a flat key pin 8. The key connection is convenient to disassemble and install, and has low processing difficulty. The flat key pin 8 used as an accessory is easy to make and has a low purchase price. The key connection provides a stable and reliable transmission force and torque, taking into account both transmission and cost-effectiveness, and is convenient for users to use.

[0049] like Figures 2 to 4 As shown, the cleaning equipment 6 includes an air delivery component 62, a high-pressure cylinder and an air pipe 63 for connecting the high-pressure cylinder, the air outlet nozzle 61 is arranged on the side of the air delivery component 62 close to the lower mold 4, the air delivery component 62 is detachably connected to the fixing frame 1, and the air pipe 63 is installed on the side of the air delivery component 62 away from the air outlet nozzle 61.

[0050] Specifically, in some embodiments, the gas delivery component 62 is a nozzle structure component responsible for outputting high-pressure gas, which is detachably mounted on the fixing frame 1 by screws. The gas outlet nozzle 61 is arranged on the side of the gas delivery component 62 close to the lower mold 4. The high-pressure cylinder is a gas storage cylinder tank for storing and releasing high-pressure gas. The gas delivery component 62 is connected to the high-pressure cylinder through the air pipe 63. The gas delivery switch is a gas valve switch arranged on the high-pressure cylinder for controlling the on and off of the gas. When cleaning is required, the gas valve switch is opened to allow the high-pressure gas to be output from the high-pressure cylinder, and then transported to the gas delivery component 62 through the air pipe 63 and ejected from the gas outlet nozzle 61. After cleaning the mold cavity 43 of the lower mold 4, the gas valve switch can be closed. It is convenient to operate and easy to control, and can quickly and effectively remove residues attached to the mold cavity 43.

[0051] like Figures 3 to 6 As shown, the front and back sides of the lower mold 4 are provided with mold cavities 43 that cooperate with the upper mold 3 .

[0052] Specifically, in some embodiments, mold cavities 43 with the same structure are arranged on both sides of the lower mold 4, so that when there is residue on the mold cavity 43 on one side, the mold cavity 43 on the other side can continue to be molded and hot-pressed with the upper mold 3 without affecting the hot-pressing work, and the mold cavity 43 with residue can be cleaned by the cleaning equipment 6 without affecting the hot-pressing work on the other side, so that the hot-pressing work can be maintained and the mold cavity 43 can be cleaned. After the mold cavity 43 on one side is contaminated, it can be immediately replaced with the other side, and this reciprocating alternation can be carried out to ensure that there is always a clean mold cavity 43 for the upper mold 3 to use, thereby improving work efficiency and processing quality.

[0053] Specifically, in some embodiments, the lower mold 4 can also be made into a rectangle with mold cavities 43 on four sides. The mold cavities 43 on the four sides can ensure to a greater extent that there are clean mold cavities 43 for the upper mold 3 to use for mold closing, thereby improving replaceability.

[0054] Specifically, in some embodiments, the lower mold 4 can also be made into a polygonal shape with mold cavities 43 on multiple sides. The multi-sided mold cavities 43 can ensure to a greater extent that there are clean mold cavities 43 for the upper mold 3 to use for mold closing, thereby improving replaceability.

[0055] like Figures 1 to 6 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0056] Under normal conditions, the flip limit block 52 is at the end of the limit groove 11, so that the upper mold 3 and the lower mold 4 can be smoothly molded. The user heats the raw material and places it on the mold cavity 43 of the lower mold 4 facing the upper mold 3. The stamping equipment 2 pushes the upper mold 3 out through the output end and presses it down to the lower mold 4. The positioning column 31 extends into the positioning cavity 42 so that the upper mold 3 and the lower mold 4 can be smoothly molded. The raw material is heated and pressed to form the product shape. After the raw material is formed, the stamping equipment 2 retracts the upper mold 3 so that the positioning column 31 is separated from the positioning cavity 42, and the hot pressing forming step is completed;

[0057] When the cavity 43 has residues of the raw material attached to it, the stamping equipment 2 is stopped, the flip handle 53 is manually held to rotate the flip part 51 to drive the flip shaft 41 to rotate, and the flip shaft 41 drives the lower mold 4 to rotate so that the cavity 43 with residues attached to it faces the air outlet nozzle 61, and the clean cavity 43 on the other side faces the upper mold 3, the flip limit block 52 rotates along the limit groove 11 around the flip shaft 41 to the other end of the limit groove 11 and then stops, the stamping equipment 2 is started, the stamping equipment 2 pushes the upper mold 3 out through the output end and presses the lower mold 4, the positioning column 31 extends into the positioning cavity 42 so that the upper mold 3 and the lower mold 4 are smoothly molded, and the raw material is heated and pressed to form the product shape, and after the raw material is formed, the stamping equipment 2 retracts the upper mold 3 so that the positioning column 31 is separated from the positioning cavity 42, and the hot pressing forming step after flipping is completed;

[0058] After flipping the lower mold 4 so that the mold cavity 43 with residue attached is facing the air outlet nozzle 61, open the air valve switch. When cleaning is needed, open the gas supply switch to allow high-pressure gas to be output from the high-pressure cylinder, transported to the gas delivery part 62 through the air pipe 63, and then ejected from the air outlet nozzle 61. The high-pressure gas is sprayed onto the surface of the mold cavity 43 to blow the residue away from the lower mold 4. After cleaning the mold cavity 43, close the gas supply switch to complete the cleaning step.

[0059] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this.
