Technical Field

[0001] This utility model relates to the field of molding machine technology, specifically a molding machine with a high-efficiency cooling function. Background Technology

[0002] Compression molding machines are widely used in various industries such as rubber, plastics, and metal processing. Their function is to press various raw materials through molds to form products of specific shapes in order to meet the production needs of different fields.

[0003] In the prior art, a molding press typically consists of a frame, a hydraulic system, a heating system, and a control system. When in use, the material to be molded is placed in the filling chamber of the lower mold. Pressure is applied to the upper mold by hydraulic pressure to close the mold with the lower mold. Under the action of filling and heating, the raw material undergoes physical or chemical changes, thereby realizing the molding process.

[0004] However, during the compression molding process, the temperature of the mold and the surface of the product is high, and the product needs to be kept in the mold for a certain period of time to cool and solidify, resulting in a long product molding cycle and low production efficiency.

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] Please see Figures 1 to 2 This utility model provides a technical solution: a molding press with high-efficiency cooling function, including a frame 1, an upper mold 2 is arranged above the frame 1, a worktable 18 is fixedly connected to the surface of the frame 1, a support plate 3 is slidably connected to the surface of the worktable 18, two lower molds 4 are fixedly connected to the surface of the support plate 3, a cooling pipe 6 is passed through the interior of the lower molds 4, a fixing plate 13 is fixedly connected to the surface of the worktable 18, a positioning pin 14 is inserted into the surface of the fixing plate 13, and the positioning pin 14 is embedded in the surface of the support plate 3;

[0025] A sliding support plate 3 is provided on the upper surface of the workbench 18. Two lower molds 4 are provided on the surface of the support plate 3, which can realize the synchronous loading and unloading, shortening the production cycle. Through the cooperation of the positioning pins 14 and positioning holes 9, the dimensional accuracy and quality stability of the molded products are improved. A cooling chamber 11 is provided inside the lower mold 4. With the help of the cooling water pump 5 and cooling pipes 6, the heat generated during the molding process is effectively removed, so that the mold and the product cool down quickly, accelerate the product cooling and shaping speed, and thus improve the overall production efficiency.

[0026] Example 2

[0027] Please see Figures 1 to 4Based on Embodiment 1, in order to enable the two lower molds 4 to work alternately, the surface of the worktable 18 is provided with a groove, the support plate 3 overlaps the surface of the groove, and the two sides of the groove are provided with track grooves 7. The surface of the track grooves 7 is fixedly connected with guide rods 8. The guide rods 8 have a cylindrical structure and can restrict the movement direction of the support plate 3, so that it can only slide along the direction of the track grooves 7, thus ensuring the stability and accuracy of the movement of the support plate 3.

[0028] A sliding plate 12 runs through the surface of the guide rod 8. The sliding plate 12 has a square plate structure. Two sliding plates 12 are fixedly connected to the two ends of the support plate 3 respectively. The sliding plate 12 is in contact with the surface of the track groove 7. Two lower molds 4 are symmetrically distributed on the surface of the support plate 3. A cooling cavity 11 is opened inside the lower mold 4. A cooling pipe 6 is set on the surface of the cooling cavity 11. The two ends of the cooling pipe 6 are connected to the surface of the water outlet and the water inlet respectively. A cooling water pump 5 is fixedly connected to the surface of the cooling pipe 6. A water tank is set at one end of the cooling water pump 5. The cooling water pump 5 draws the coolant from the water tank, pressurizes it and sends it into the cooling pipe 6, so that the coolant circulates in the pipe.

[0029] Example 3

[0030] Please see Figures 1 to 5 Based on Embodiment 2, in order to limit the support plate 3, handles 10 are fixedly connected to both ends of the support plate 3. The handles 10 facilitate the operator to push and pull the support plate 3. Two positioning holes 9 are opened on one side of the support plate 3. Positioning pins 14 are embedded in the surface of the positioning holes 9. When the support plate 3 moves to the appropriate position, the positioning pins 14 are inserted into the positioning holes 9, which can quickly and accurately fix the position of the support plate 3, ensure that the lower mold 4 will not be displaced during the molding process, ensure the precise alignment of the upper mold 2 and the lower mold 4, and thus ensure the dimensional accuracy and quality stability of the molded product.

[0031] The positioning pin 14 has a cylindrical structure. A connecting block 15 is fixedly connected to the end of the positioning pin 14 away from the positioning hole 9. The connecting block 15 has a T-shaped circular plate structure. The connecting block 15 provides an easy part for the operator to grip and insert / remove the positioning pin 14. The fixing plate 13 has a square plate structure. A rubber groove 19 is opened on the surface of the fixing plate 13. Through grooves are opened on both ends of the fixing plate 13. The through grooves are connected to the rubber groove 19. The diameter of the through groove is larger than the diameter of the rubber groove 19. The positioning pin 14 passes through the surface of the rubber groove 19.

[0032] A limiting plate 17 is fixedly connected to the surface of the positioning pin 14. The limiting plate 17 has an annular plate structure and moves on the surface of the rubber groove 19 to limit the movement range of the positioning pin 14 and prevent it from falling off. A rubber sleeve 16 is fixedly connected to one end of the limiting plate 17 and the other end of the rubber sleeve 16 is fixedly connected to the surface of the rubber groove 19. The rubber sleeve 16 is fitted on the surface of the positioning pin 14, which enhances the fixing effect and stability of the positioning pin 14.

[0033] In actual use, the material to be processed is first placed on the lower mold 4. The upper mold 2 and the lower mold 4 are closed. Under pressure, the material is molded and formed into the required shape. Then, the upper mold 2 and the lower mold 4 are separated, and the cooling water pump 5 starts to work, delivering coolant to the cooling pipe 6. The coolant circulates in the cooling pipe 6 and absorbs the heat generated by the lower mold 4 during the molding process through heat exchange, thereby reducing the temperature of the lower mold 4 and allowing the molded product to cool and solidify quickly.

[0034] Simultaneously, the operator pulls the connecting block 15 away from the end of the support plate 3. The connecting block 15 drives the positioning pin 14 to move and separate from the positioning hole 9. At this time, the support plate 3 loses its limit. Then, the operator pulls the handle 10 on the surface of the support plate 3 to move another lower mold 4 containing the material to be processed to the lower part of the upper mold 2. When the positioning pin 14 is aligned with the corresponding positioning hole 9, the positioning pin 14 is snapped into the corresponding positioning hole 9 again to achieve the positioning and fixing of the support plate 3 and the lower mold 4. At this time, the lower mold 4 located below the upper mold 2 works, while the other lower mold 4 has enough time to cool and reload, thereby improving the cooling efficiency and loading efficiency of the lower mold 4.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
