[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figures 1 - 5, A complete mold O-ring mold for automated demolding, including an upper mold core 1. The surface of the upper mold core 1 is provided with a complete mold mechanism 2. The complete mold mechanism 2 realizes the action of integrally forming multiple O-rings in a consistent manner. The front end face and the rear end face of the upper mold core 1 are both provided with T-shaped upper mold clamping grooves 3, and the T-shaped upper mold clamping grooves 3 penetrate through the upper mold core 1. The T-shaped horizontal ends of the T-shaped upper mold clamping grooves 3 are located on the top surface of the upper mold core 1, and the T-shaped vertical ends of the T-shaped upper mold clamping grooves 3 are located on the bottom surface of the upper mold core 1.

[0020] Specifically, by setting the complete mold mechanism 2 on the surface of the upper mold core 1, the integral and consistent forming of multiple O-rings can be realized, which improves production efficiency, reduces labor costs, and is suitable for large-scale automated production; the complete mold mechanism 2 ensures the consistency of the sizes and shapes of multiple O-rings, reduces product differences, and improves product quality; the design of the T-shaped upper mold clamping grooves 3 enables the mold to be more easily coordinated with automated equipment on the automated production line to achieve rapid and precise demolding operations; automated demolding reduces the risk of workers directly contacting the hot mold and improves the safety of the production process.

[0021] The complete mold mechanism 2 includes O-ring cavities 4 opened on the top surface of the upper mold core 1. Multiple O-ring cavities 4 are linearly arranged and distributed in the horizontal direction. Multiple O-ring cavities 4 are grouped in twos in the vertical direction, and multiple groups of O-ring cavities 4 are linearly arranged and distributed in the vertical direction.

[0022] Specifically, by linearly arranging multiple O-ring cavities 4 in the horizontal direction, multiple O-rings can be produced within one vulcanization cycle, significantly increasing the output per unit time; arranging multiple groups of O-ring cavities 4 in the vertical direction can more effectively utilize the mold space, making the mold design more compact and saving the floor area of the equipment; since multiple O-ring cavities 4 are arranged according to a certain pattern, this helps to ensure a high degree of consistency of the products produced in batches and reduces quality fluctuations; the linear arrangement in the vertical and horizontal directions helps to evenly distribute the temperature inside the mold, thereby ensuring that each O-ring can be vulcanized evenly and improving the product qualification rate.

[0023] The front end and the rear end of the upper mold core 1 are also provided with alignment holes 5. Four alignment holes 5 are arranged in a rectangular array, and all four T-shaped upper mold clamping grooves 3 are located between the four alignment holes 5.

[0024] Specifically, the design of the alignment holes 5 enables the upper mold core 1 to be accurately aligned with the lower mold core or other mold components, ensuring the accuracy of the sizes and shapes of the O-rings; the alignment holes 5 arranged in a rectangular array facilitate quick positioning and assembly, reduce the mold assembly time, and improve production efficiency.

[0025] Circular incision taper grooves 6 are provided on both the outer and inner sides of each O-shaped cavity 4. An integral mold lace 7 is provided on the outer side of the circular incision taper groove 6, and the integral mold lace 7 surrounds a plurality of O-shaped cavities 4.

[0026] Specifically implemented in this way, the circular incision taper groove 6 helps to guide the flow of rubber material in the mold, enabling it to fill each corner of the O-shaped cavity 4 more evenly, reducing problems such as underfilling or overfilling; the design of the taper groove can reduce the adhesion force between the O-ring and the mold, making demolding easier and reducing damage to the product; the integral mold lace 7 surrounds a plurality of O-shaped cavities 4, ensuring the consistency of multiple O-rings during the molding process and reducing product differences.

[0027] The sinking depth dimension of the integral mold lace 7 is 0.5 MM, and the dimension of the integral mold lace 7 close to the circular incision taper groove 6 is 1 MM.

[0028] Specifically implemented in this way, the sinking design of the integral mold lace 7 helps to provide additional space during demolding, reducing the friction between the O-ring and the mold, making demolding smoother; the precise dimension of the integral mold lace 7 can ensure that the edge of the O-ring is smooth and beautiful, improving the appearance quality of the product; by adding the lace, the redundancy of the fabric is increased, solving the problem of inaccurate product dimensions caused by excessive fabric quantity; at the same time, it can also improve the fabric speed and increase production capacity. After adding the lace, it also gives space for the overflow material to flow, reducing the probability of sticking skin on the product, improving the product quality, and saving subsequent processing costs.

[0029] On the inner wall of the integral mold lace 7 between every two opposite circular incision taper grooves 6, a diversion groove 8 is also provided, and the width dimension of the diversion groove 8 is 3 MM.

[0030] Specifically implemented in this way, the diversion groove 8 helps to guide the flow of rubber material in the mold, ensuring that the material can fill each part of the O-shaped cavity 4 evenly. Especially for cavities with complex shapes, the diversion groove 8 can significantly improve the filling effect; due to the existence of the diversion groove 8, the flow of rubber material is smoother, the vulcanization cycle can be shortened, and the production efficiency can be improved; the diversion groove 8 helps to achieve a more uniform pressure distribution in the cavity, thereby improving the dimensional accuracy and consistency of the O-ring finished product.

[0031] By setting up the integral mold mechanism 2, the integral and consistent molding of multiple O-rings is achieved, which improves production efficiency, reduces labor costs, and is suitable for large-scale automated production. Moreover, the automated demolding is integral and consistent without residue, and lace is made on the outside of the cavity as a whole to ensure that the semi-finished product presents an integral mold state with minimal additional material consumption. The fine size of the integral mold lace 7 can also ensure that the edge of the O-ring is smooth and beautiful, improving the appearance quality of the product. After adding the lace, the redundancy of the fabric will be increased, solving the problem of inaccurate product dimensions caused by excessive fabric. At the same time, it can also improve the fabric speed and increase production capacity. After adding the lace, it also provides a flow space for the overflow material, reducing the probability of sticking skin on the product, improving the product quality, and saving the subsequent processing cost.
