Description

Technical Field

[0001] The invention relates to the technical field of production moulds, in particular to a rubber shock-absorbing column production mould and a production process thereof. Background Art

[0002] Rubber shock-absorbing columns are usually used in building structures or mechanical equipment, mainly to reduce vibration and noise transmission. They are made of rubber materials with good elasticity and durability. These shock-absorbing columns can reduce the vibration generated by buildings or mechanical equipment during operation by absorbing vibration energy, thereby improving the working environment or extending the service life of the equipment.

[0003] In the process of injection molding of the rubber shock-absorbing column production mold in the prior art, the rubber liquid will penetrate into the hole for storing the screw because the screw and the mold are not tightly fitted. This causes the rubber to adhere to the surface of the screw after demolding. In order to avoid the normal use of the rubber shock-absorbing column, it is often necessary to increase manpower to clean the excess rubber adhered to the surface of the rubber shock-absorbing column screw. For this reason, we have introduced a rubber shock-absorbing column production mold and its production process. Summary of the invention

[0004] The object of the present invention is to provide a rubber shock-absorbing column production mold and a production process thereof to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A rubber shock-absorbing column production mold comprises a molding module, wherein the upper and lower ends of the molding module are both provided with connecting modules, the upper end of the molding module is provided with two groups of molding cavities, the molding cavities are provided with two groups of limiting mechanisms, the screws are limited and tightened by the limiting mechanisms, the opposite surfaces of the two groups of connecting modules are both fixedly connected with two groups of clamping airbag rings, and the two groups of clamping airbag rings are connected to the liquid pushing mechanism;

[0007] The liquid pushing mechanism is arranged in the connecting module, and contacts with the forming module through the connecting module, so that the liquid pushing mechanism pushes the hydraulic oil into the clamping airbag ring after being squeezed, so that the clamping airbag ring contacts with the screw. The inner side of the clamping airbag ring is arranged in an arc shape, and the inner side of the clamping airbag ring is connected with the positioning hole. The positioning hole is opened in the connecting module, and the screw is positioned by inserting the screw into the positioning hole.

[0008] Preferably, the limiting mechanism includes a T-shaped sliding rod, which is slidably connected in a sliding cavity. The sliding cavity is opened in the molding module, and the T-shaped sliding rod extends into the molding cavity away from one end of the sliding cavity. A first spring is fixedly connected in the sliding cavity, and the other end of the first spring is fixedly connected to the T-shaped sliding rod.

[0009] Preferably, a limiting cavity is opened in the upper end of the T-shaped sliding rod, a T-shaped limiting block is slidably connected in the limiting cavity, the upper end of the T-shaped limiting block extends into the forming cavity, two groups of second springs are fixedly connected in the limiting cavity, and the other end of the second spring is fixedly connected to the T-shaped limiting block.

[0010] Preferably, the liquid pushing mechanism includes a T-shaped pressure block, which is slidably connected in the connecting cavity, which is opened in the connecting module, and the T-shaped pressure block extends into the external environment at one end away from the connecting cavity. The two sides of the connecting cavity are respectively connected to the liquid guiding cavity, which is opened in the connecting module, and the liquid guiding cavity is connected to the clamping airbag ring at one end away from the connecting cavity. Hydraulic oil is provided in the connecting cavity and the clamping airbag ring.

[0011] Preferably, the connecting module is fixedly connected to one end of the molding module close to a plurality of positioning rods, the upper end of the molding module is provided with a plurality of positioning through holes, the inner side of the positioning holes is fixedly connected with a magnetic ring, the upper end of the molding module is provided with a liquid guide groove, and the liquid guide groove is communicated with two groups of molding cavities.

[0012] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a production process for the above-mentioned rubber shock-absorbing column production mold:

[0013] S1. Insert the screw into the positioning hole so that the screw is fixed by the magnetic ring. Move the positioning rod along the positioning through hole so that the screw can correspond to the position of the molding cavity. When the screw contacts the upper end of the T-shaped limit block, as the connection module continues to move downward, the T-shaped limit block will be pressed into the limit cavity. Under the elastic force of the second spring, the T-shaped limit block presses the screw;

[0014] S2. As the connection module moves, the T-shaped pressure block will be squeezed into the connection cavity, so that the hydraulic oil is pushed into the compression airbag ring and contacts the arc position of the screw.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-5 , the present invention provides a technical solution: Example

[0025] A rubber shock-absorbing column production mold includes a molding module 11, and the upper and lower ends of the molding module 11 are both provided with a connecting module 1. Two groups of molding cavities 3 are opened in the upper end of the molding module 11, and two groups of limiting mechanisms are provided in the molding cavity 3. The limiting mechanisms are used to limit and tighten the screw 9. Two groups of clamping airbag rings 10 are fixedly connected to the opposite surfaces of the two groups of connecting modules 1, and the two groups of clamping airbag rings 10 are connected to the liquid pushing mechanism;

[0026] The liquid pushing mechanism is arranged in the connecting module 1, and contacts with the forming module 11 through the connecting module 1, so that the liquid pushing mechanism pushes the hydraulic oil into the clamping airbag ring 10 after being squeezed, so that the clamping airbag ring 10 contacts with the screw 9, and the inner side of the clamping airbag ring 10 is arranged in an arc shape, and the inner side of the clamping airbag ring 10 is connected with the positioning hole 8. The positioning hole 8 is opened in the connecting module 1, and the inner side of the positioning hole 8 is fixedly connected with a magnetic ring 5. The screw 9 is inserted into the positioning hole 8. Since the magnetic ring 5 is provided on the inner side of the positioning hole 8, when the screw 9 enters the positioning hole 8, it will be limited and fixed by the magnetic ring 5. Example

[0027] On the basis of Example 1, in order to prevent the upper and lower screw rods 9 from moving when the compression airbag ring 10 expands and compresses the screw rod 9, the limiting mechanism includes a T-shaped slide bar 16, the T-shaped slide bar 16 is slidably connected in the sliding cavity 17, the sliding cavity 17 is opened in the molding module 11, the T-shaped slide bar 16 extends into the molding cavity 3 away from the sliding cavity 17, and a first spring 18 is fixedly connected in the sliding cavity 17, and the other end of the first spring 18 is fixedly connected to the T-shaped slide bar 16, and the opposite ends of the two groups of T-shaped slide bars 16 are arranged in an arc shape. When the molding cavity 3 is filled with rubber liquid, as the rubber liquid is continuously injected into the molding cavity 3, the two groups of T-shaped slide bars 16 enter the sliding cavity 17 under the extrusion of the rubber liquid, so that the first spring 18 is compressed, and after the T-shaped slide bar 16 is completely received in the sliding cavity 17, the molding cavity 3 forms a complete circular cavity;

[0028] A limiting cavity 14 is provided in the upper end of the T-shaped slide bar 16, and a T-shaped limiting block 15 is slidably connected in the limiting cavity 14. The upper end of the T-shaped limiting block 15 extends into the molding cavity 3. Two sets of second springs 13 are fixedly connected in the limiting cavity 14. The other end of the second spring 13 is fixedly connected to the T-shaped limiting block 15. After the screw rod 9 contacts the upper end of the T-shaped limiting block 15, as the connection module 1 continues to move downward, the T-shaped limiting block 15 will be pressed into the limiting cavity 14. At this time, the second spring 13 is compressed. At the same time, under the elastic force of the second spring 13, the T-shaped limiting block 15 presses the screw rod 9;

[0029] The liquid pushing mechanism includes a T-shaped pressing block 12, which is slidably connected in the connecting cavity 7, and the connecting cavity 7 is arranged in the connecting module 1. The end of the T-shaped pressing block 12 away from the connecting cavity 7 extends into the external environment, and the two sides of the connecting cavity 7 are respectively connected with the liquid guiding cavity 6, and the liquid guiding cavity 6 is arranged in the connecting module 1. The end of the liquid guiding cavity 6 away from the connecting cavity 7 is connected with the clamping airbag ring 10, and hydraulic oil is provided in the connecting cavity 7 and the clamping airbag ring 10. When the T-shaped pressing block 12 contacts the forming module 11, the T-shaped pressing block 12 will be squeezed into the connecting cavity 7 as the connecting module 1 moves. At this time, the hydraulic oil in the connecting cavity 7 will be pushed into the clamping airbag ring 10, so that the clamping airbag ring 10 expands outward and contacts the arc position of the screw 9, thereby preventing the rubber liquid from entering the positioning hole 8 and adhering to the surface of the screw 9;

[0030] The connecting module 1 is fixedly connected to one end close to the molding module 11 with a plurality of positioning rods 4, and the upper end of the molding module 11 is provided with a plurality of positioning through holes 2. The positioning rods 4 move along the positioning through holes 2 so that the screw 9 can correspond to the position of the molding cavity 3. A magnetic ring 5 is fixedly connected to the inner side of the positioning hole 8. A liquid guide groove 19 is provided at the upper end of the molding module 11, and the liquid guide groove 19 is connected to the two groups of molding cavities 3. Rubber liquid can be injected into the two groups of molding cavities 3 through the liquid guide groove 19.

[0031] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a production process for the above-mentioned rubber shock-absorbing column production mold.

[0032] S1. Insert the screw 9 into the positioning hole 8 so that the screw 9 is fixed by the magnetic ring 5. Move the positioning rod 4 along the positioning through hole 2 so that the screw 9 can correspond to the position of the molding cavity 3. When the screw 9 contacts the upper end of the T-shaped limit block 15, as the connection module 1 continues to move downward, the T-shaped limit block 15 will be pressed into the limit cavity 14. Under the elastic force of the second spring 13, the T-shaped limit block 15 presses the screw 9;

[0033] S2. As the connection module 1 moves, the T-shaped pressing block 12 will be squeezed into the connection cavity 7, so that the hydraulic oil is pushed into the compression airbag ring 10 and contacts the arc position of the screw 9. When both sets of connection modules 1 are in contact with the molding module 11, the rubber liquid can be injected into the two sets of molding cavities 3 through the liquid guide groove 19;

[0034] S3. When the molding cavity 3 is filled with rubber liquid, as the rubber liquid is continuously injected into the molding cavity 3, the two groups of T-shaped slide bars 16 enter into the sliding cavity 17 under the extrusion of the rubber liquid. When the connected T-shaped slide bars 16 completely enter into the sliding cavity 17, the injection molding is completed. After the rubber is cooled and formed, the upper and lower connecting modules 1 are separated, and the molded rubber shock-absorbing column 100 is taken out.

[0035] Working principle: when in use, the screw rod 9 is inserted into the positioning hole 8. Since a magnetic ring 5 is provided on the inner side of the positioning hole 8, when the screw rod 9 enters the positioning hole 8, it will be limited and fixed by the magnetic ring 5. The positioning rod 4 moves along the positioning through hole 2, so that the screw rod 9 can correspond to the position of the molding cavity 3. When the screw rod 9 contacts the upper end of the T-shaped limit block 15, as the connection module 1 continues to move downward, the T-shaped limit block 15 will be pressed into the limit cavity 14. At this time, the second spring 13 is compressed. At the same time, under the elastic force of the second spring 13, the T-shaped limit block 15 presses the screw rod 9.

[0036] When the T-shaped pressing block 12 contacts the forming module 11, the T-shaped pressing block 12 will be squeezed into the connecting cavity 7 as the connecting module 1 moves. At this time, the hydraulic oil in the connecting cavity 7 will be pushed into the clamping airbag ring 10, so that the clamping airbag ring 10 expands outward and contacts the arc position of the screw 9, preventing the rubber liquid from entering the positioning hole 8 and adhering to the surface of the screw 9;

[0037] When the two groups of connecting modules 1 are in contact with the forming module 11, rubber liquid can be injected into the two groups of forming cavities 3 through the liquid guiding groove 19. When the forming cavity 3 is filled with rubber liquid, as the rubber liquid is continuously injected into the forming cavity 3, the two groups of T-shaped slide bars 16 enter the sliding cavity 17 under the extrusion of the rubber liquid, so that the first spring 18 is compressed. When the connecting T-shaped slide bar 16 completely enters the sliding cavity 17, the injection molding is completed. After the rubber is cooled and formed, the upper and lower connecting modules 1 can be separated. After the formed rubber shock absorber column 100 is taken out, the T-shaped slide bar 16 pops out again under the elastic force of the first spring 18, and the T-shaped limit block 15 pops out again under the elastic force of the second spring 13.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
