[0030] Easy demoulding mold for rubber cushioning workpieces, such as Figure 1-Figure 3As shown, it includes a lower mold 10 and an upper mold 40 for producing rubber buffer workpieces. One end of the lower mold 10 is provided with an end seat 20 flush with its top surface, and the bottom of the lower mold 10 is provided with a base 30; the top surface of the lower mold 10 is provided with a plurality of mold grooves 11 arranged evenly and equidistantly, and an ejector plate 12 is installed at the bottom of each mold groove 11; two sets of synchronously working push cylinders 21 are installed on the end seat 20, and a push bar 22 is slidably installed on the top surface of the lower mold 10. The push of the push cylinder 21 The rod is connected to the push bar 22; both ends of the base 30 are equipped with synchronous ejection cylinders 32, and a movable ejection plate 31 is installed in parallel between the lower mold 10 and the base 30. The piston rods of the two sets of ejection cylinders 32 are connected to the top of the ejection plate 31. The top surface of the ejection plate 31 is equipped with demoulding ejector rods 33 with the same number, corresponding position and coaxial connection as the ejection plate 12. The lower mold 10 is set, and the top surface thereof is provided with a number of evenly and equidistantly arranged mold grooves 11, which are rubber buffers. The molding of the workpiece provides a spatial and shape basis; the ejector plate 12 installed at the bottom of the mold groove 11 plays an important supporting and auxiliary role in the demolding process; the two sets of synchronously working push cylinders 21 installed on the end seat 20, and the push bar 22 connected to the push rod of the push cylinder 21, enable the push bar 22 to slide through the action of the push cylinder 21 during demolding, thereby applying a certain thrust to the molded rubber buffer workpiece to assist its demolding; the synchronously working ejector cylinders 32 installed at both ends of the base 30, and the movable ejector plate 31 installed parallel to the lower mold 10 and the base 30, and the demolding ejector rod 33 installed on the top surface of the ejector plate 31 with the same number, corresponding position and coaxial connection as the ejector plate 12. During the demolding process, the ejector cylinder 32 works to push the ejector plate 31 upward, thereby driving the demolding ejector rod 33 to eject upward, and eject the rubber buffer workpiece located in the mold groove 11 from the bottom to the top, realizing efficient and accurate demolding operation.

[0031] Furthermore, supporting side seats 13 are symmetrically provided on both sides of the lower mold 10, and the lower mold 10 and the two groups of supporting side seats 13 are connected in an H-shape, so that the mold is more stable when subjected to the mold closing pressure, reducing the risk of mold deformation and damage.

[0032] Among them, the length of the pushing bar 22 is the same as the spacing between the two groups of supporting side seats 13, and the two ends of the pushing bar 22 slide together with the two groups of supporting side seats 13, ensuring the stability and accuracy of the pushing bar 22 during the sliding process, thereby ensuring the smooth progress of the mold closing and opening actions. The width of the upper mold 40 is the same as the spacing between the two groups of supporting side seats 13. A lifting cylinder 41 for adjusting the height is installed on the top of the upper mold 40. Accurate height adjustment is achieved through the lifting cylinder 41, thereby ensuring the mold closing accuracy and product quality of the mold.

[0033] It is worth noting that the maximum stroke of the pushing cylinder 21 is the same as the width of the lower mold 10. The pushing cylinder 21 can completely cover the width of the lower mold 10 during the pushing process, thereby achieving complete removal of the mold.

[0034] Among them, the ejection plate 12 rises to the highest point position, and the top surface is flush with the top surface of the lower mold 10, so that the demoulding base 12 will not interfere with the lower mold 10 when ejecting the workpiece, thereby ensuring smooth demoulding of the workpiece.

[0035] In addition, supporting side seats 13 are also installed on both sides of the end seat 20, which enhances the stability and rigidity of the mold and makes the mold more stable when subjected to various external forces.

[0036] Working principle of the easy demoulding mold of the rubber buffer workpiece:

[0037] The rubber raw material is placed in the mold cavity 11 of the lower mold 10 to prepare for the molding operation, and the upper mold 40 is closed to perform the molding process of the rubber cushion workpiece;

[0038] When the rubber buffer workpiece is formed, the ejection cylinders 32 at both ends of the base 30 are started to work synchronously;

[0039] The piston rod of the ejection cylinder 32 pushes the movable ejection plate 31 installed parallel to the lower mold 10 and the base 30 to move upward;

[0040] As the ejector plate 31 moves upward, the ejector pins 33 installed on the top surface of the ejector plate 31 and having the same number, corresponding positions and coaxial connection with the ejector base 12 also move upward.

[0041] The demoulding ejector 33 ejects the rubber buffer workpiece located in the mold groove 11 from the bottom upward to complete the demoulding operation;

[0042] Finally, start the two sets of synchronously working pushing cylinders 21 on the end seat 20. The pushing rods of the pushing cylinders 21 push the pushing bars 22 slidably installed on the top surface of the lower mold 10. The pushing bars 22 slide toward the rubber buffer workpiece, applying a certain lateral thrust to the ejected rubber buffer workpiece for collection.
