Description

Technical Field

[0001] The utility model relates to the field of seal ring production, in particular to a high-efficiency automatic forming machine for rubber seal rings. Background Art

[0002] In aerospace products and some mechanical devices, seal rings are required. During the transmission process of pneumatic or hydraulic devices, the seal rings play a sealing role, which can prevent gas or liquid from overflowing and ensure the normal operation of the devices; most seal rings are circular rings made of rubber material and are hot-pressed through a mold. Specifically, the raw rubber block is placed on the upper surface of the mold, and the pressing plate above the mold moves downward and presses on the upper surface of the mold. In this way, under the action of heat and pressure, the raw rubber is formed into a seal ring.

[0003] However, the surrounding environment of some molds and pressing plates is open. During operation, the temperature dissipates relatively quickly, and it is difficult for the temperatures of the molds and pressing plates to remain constant for a long time. This will cause the quality of the hot-pressed seal rings to be unstable and have a high rejection rate.

[0004] In view of the above problems, the present utility model is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a high-efficiency automatic forming machine for rubber seal rings to solve the problems mentioned in the background art.

[0027] As Figures 1-3 shown, a high-efficiency automatic rubber sealing ring forming machine includes a cabinet 1, a top plate 14, a heat-insulating baffle 2 and an insertion plate 21. Four support rods 15 are vertically and symmetrically arranged around the upper surface of the cabinet 1. The top plate 14 is located directly above the cabinet 1, and the upper ends of the support rods 15 are fixed to the lower surface of the top plate 14; the support rods 15 play a supporting role for the top plate 14;

[0028] Two hydraulic cylinders 16 are symmetrically arranged on the top plate 14. The telescopic cylinders of the hydraulic cylinders 16 face downward and are provided with a first electric heating plate 17. A second electric heating plate 18 is arranged in the middle of the upper surface of the cabinet 1. The first electric heating plate 17 is located directly above the second electric heating plate 18. When the hydraulic cylinder 16 extends, it drives the first electric heating plate 17 to move downward;

[0029] The horizontal cross-section of the heat-insulating baffle 2 is in an "n" shape. The heat-insulating baffle 2 is located between the upper surface of the cabinet 1 and the lower surface of the top plate 14. The insertion plate 21 is located at the front open position of the heat-insulating baffle 2. Through the front open position of the heat-insulating baffle 2, the sealing ring raw material can be put in or the formed sealing ring can be taken out. The insertion plate 21 is inserted up and down with the front upper surface of the top plate 14. Both the first electric heating plate 17 and the second electric heating plate 18 are located inside the heat-insulating baffle 2 and the insertion plate 21. When the insertion plate 21 moves upward, the front open position of the heat-insulating baffle 2 is exposed.

[0030] Three inner sides of the heat preservation baffle 2 are each provided with a temperature sensor 23, and an industrial control display screen 22 is arranged on the outer side of the heat preservation baffle 2. The three temperature sensors 23 are all connected to the industrial control display screen 22 in signal. The three temperature sensors 23 can detect the temperature inside the heat preservation baffle 2. When the detection data of the three temperature sensors 23 are consistent, it means that the temperatures at various positions inside the heat preservation baffle 2 are the same.

[0031] First screw holes are arranged at four corner positions on the lower surface of the first electric heating plate 17, and second screw holes are arranged at four corner positions on the upper surface of the second electric heating plate 18.

[0032] Two cabinet doors 11 are arranged on the front surface of the cabinet 1. The cabinet doors 11 are hinged to the cabinet 1. A handle 12 is arranged at a position on the front surface of the cabinet door 11 far from its rotating shaft. Support feet 13 are arranged at four corners on the lower surface of the cabinet 1.

[0033] The height of the plug board 21 is greater than the distance between the cabinet 1 and the top plate 14. A handle groove is arranged above the front surface of the plug board 21. Through the handle groove, the plug board 21 can be conveniently moved up and down.

[0034] Both the heat preservation baffle 2 and the plug board 21 are transparent, which is convenient for observing the internal situation.

[0035] A slot is arranged on the upper surface of the cabinet 1 at a position directly below the plug board 21.

[0036] In summary: The lower die holder of the mold is installed on the upper surface of the second electric heating plate 18 through bolts, and the upper template of the mold is installed on the lower surface of the first electric heating plate 17 through bolts. After the first electric heating plate 17 and the second electric heating plate 18 are electrified and generate heat, the upper template and the lower die holder can be heated;

[0037] After the hydraulic cylinder 16 extends out, it can drive the first electric heating plate 17 and the upper template to move downward. The raw material of the sealing ring is placed on the lower die holder. In this way, after the upper template enters the lower die holder, the raw material of the sealing ring can be hot-pressed to obtain the sealing ring;

[0038] When the plug board 21 is moved upward, the raw material of the sealing ring can be placed on the lower die holder, and then the plug board 21 is inserted downward. In this way, the raw material of the sealing ring is in a heat-preserved environment. The three temperature sensors 23 can detect the temperature inside the heat preservation baffle 2. When the temperatures displayed by the three temperature sensors 23 on the industrial control display screen 22 are the same, the hydraulic cylinder 16 extends out, and the upper template moves downward to hot-press and form the raw material of the sealing ring;

[0039] The raw material of each batch of sealing rings can be hot-pressed and formed in a constant temperature environment. In this way, the quality of each batch of sealing rings can be kept consistent, and the finished product rate is higher.
