Description

Technical Field:

[0001] The utility model relates to the technical field of rubber processing equipment, and more specifically to a forming device of a rubber part extrusion molding machine. Background Art:

[0002] In the existing rubber part processing, one of the steps is to place the rubber material on the lower die, and then, by pressing down the upper die, the rubber material is located between the upper die and the lower die. At the same time, heating is carried out so that the rubber material is in the forming grooves of the upper die and the lower die to achieve forming.

[0003] However, the existing rubber material is generally manually placed on the lower die, and then, the upper die descends for die pressing operation. When manually placing, it is directly operated below the upper die, and the operation range is limited. Moreover, if a manipulator is used for automatic feeding, it cannot be well realized and cannot be used in automated continuous production. Summary of the Utility Model:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a forming device of a rubber part extrusion molding machine, which can move the lower die out to the left with the bottom die moving plate so that it is not below the upper die, facilitating manual feeding or automatic feeding by a manipulator. The feeding is convenient, and it can be combined with an automatic feeding device and installed for use in automatic continuous production, which is very convenient.

At least one pushing oil cylinder is fixed on the top surface of the installation plate, and the push rod of the pushing oil cylinder moves the bottom die moving plate left and right.

[0010] On the top surface of the mounting plate, two pushing oil cylinders are fixed. The ends of the push rods of the two pushing oil cylinders are movably connected to one end of an adjusting rod assembly through a hinge shaft. The other end of the adjusting rod assembly is movably connected to a connecting seat through a hinge shaft. The two connecting seats are fixed on the right side wall of the bottom die moving plate.

An upper die 30 is fixed on the bottom surface of the upper pressing block 18;

[0021] In the middle of the top surface of the bottom die moving plate 20, a bottom die 21 is fixedly provided. The bottom die 21 corresponds to the upper die 30 up and down;

[0022] On the bottom surface of the right part between the two transverse guiding beams 14, a mounting plate 141 is fixedly provided. On the top surface of the mounting plate 141, at least one pushing oil cylinder 40 is fixedly provided. The push rod of the pushing oil cylinder 40 moves the bottom die moving plate 20 left and right.

[0023] Furthermore, two pushing oil cylinders 40 are fixedly provided on the top surface of the mounting plate 141. The ends of the push rods of the two pushing oil cylinders 40 are movably connected with one end of an adjusting rod assembly 143 through a hinge shaft. The other end of the adjusting rod assembly 143 is movably connected with a connecting seat 144 through a hinge shaft. The two connecting seats 144 are fixed on the right side wall of the bottom die moving plate 20.

[0024] The adjusting rod assembly 143 includes two middle main rod bodies 1431 movably connected through a hinge shaft. At the middle parts of the two ends of the two middle main rod bodies 1431 far away from each other, screw holes are formed. The screw part of the end connecting head 1432 is screwed in the corresponding screw hole. The end of the push rod of the pushing oil cylinder 40 is movably connected with the corresponding end connecting head 1432 through a hinge shaft. The end connecting head 1432 at the other end is movably connected with the connecting seat 144 through a hinge shaft.

[0025] With this structure, by rotating the corresponding end connecting head 1432, the total length of the adjusting rod assembly 143 can be changed. At the same time, through the adjusting rod assembly 143, when there is a small time difference when the push rods of the two pushing oil cylinders 40 push, it will not get stuck and can still realize normal telescopic pushing.

[0026] Furthermore, between the lower parts of the middle parts of the two transverse guiding beams 14, an intermediate support plate 145 is fixedly provided. The bottom surface of the intermediate support plate 145 is pressed against the top surface of the bottom pushing block 13;

[0027] On the inner side walls of the two transverse guiding beams 14, transverse guiding grooves are formed. The front and rear parts of the bottom die moving plate 20 are inserted into the corresponding transverse guiding grooves. Both ends of the guiding rod 22 extending left and right are fixed on the end plates fixed at the left and right ends of the transverse guiding grooves. The end plates are fixed on the inner side wall at one end of the transverse guiding groove of the corresponding transverse guiding beam 14. The guiding rod 22 is inserted into the transverse guiding through holes at the front or rear part of the bottom die moving plate 20;

[0028] The bottom surface of the bottom die moving plate 20 is closely attached to the top surface of the middle support plate 145.

[0029] Furthermore, the same left horizontal connecting plate 146 is fixed on the bottom surfaces of the left parts of the two transverse guiding beams 14. A plurality of vertical rods 1 are fixed on the front and rear parts of the left horizontal connecting plate 146. The bottom of the vertical rod 1 extends out of the bottom surface of the left horizontal connecting plate 146 and is inserted into the guiding sleeve bodies 3 fixed on the top surfaces of the connecting blocks 2 fixed on the ground below the left parts of the two transverse guiding beams 14.

[0030] Furthermore, the tops of all the vertical rods 1 extend out of the top surface of the left horizontal connecting plate 146 and are fixed on the corresponding upper horizontal plates 4. The upper horizontal plates 4 are fixed on the outer side walls of the left parts of the corresponding transverse guiding beams 14.

[0031] Furthermore, a side connecting seat 50 is fixed on the outer side wall of the middle part of a transverse guiding beam 14. A second pushing oil cylinder 51 is fixed on the outer side wall of the vertical plate on the top surface of the side connecting seat 50. The end of the push rod of the second pushing oil cylinder 51 extends out of the inner side wall of the vertical plate and is fixed with a mounting bracket 52. A proximity switch 53 is fixed on the mounting bracket 52. The sensing end of the proximity switch 53 extends out of the inner side wall of the mounting bracket 52 and corresponds to the sensing end 31 fixed on the middle part of the outer side wall of the upper die 30. This structure enables that when the proximity switch 53 does not need to sense, the push rod of the second pushing oil cylinder 51 can be retracted so that it no longer senses and is used.

[0032] Furthermore, a plurality of outer guiding rods 5 are fixed on the outer side wall of the mounting bracket 52. The outer guiding rods 5 are inserted into the guiding through holes formed on the vertical plate.

[0033] Furthermore, a plurality of upper guiding rods 6 are fixed on the edge of the top surface of the upper pressing block 18. The upper guiding rods 6 are inserted into the corresponding vertical guiding through holes formed on the upper fixing block 16.

[0034] In use, this embodiment is pushed by the push rods of two pushing oil cylinders 40, causing the bottom die moving plate 20 to move leftward to the leftmost end. At this time, the bottom surface of the front part of its left end is sensed by the top end of the lower proximity switch fixed on the bottom plate at the left end of the front horizontal guiding beam 14 (the top end of the lower proximity switch extends out of the top surface of the bottom plate at the left end of the front horizontal guiding beam 14), indicating that its movement is in place. At this time, the lower die 21 is not directly below the upper die 30. At this time, rubber material can be manually or automatically placed on the top surface of the lower die 21 by a manipulator. Then, by retracting the push rods of the two pushing oil cylinders 40, the lower die 21 is moved to the top surface of the intermediate support plate 145. At this time, the sensing end of the proximity switch 53 senses the sensing end 31 fixed in the middle of the outer wall of the upper die 30, indicating that its movement is in place. Then, by pushing the push rod of the bottom pushing oil cylinder 12, the lower die 21 is lifted. Then, by pushing the push rod of the upper pressing oil cylinder 17, the upper die 30 is lowered and pressed against the lower die 21. At the same time, heating devices and cold runner devices are provided in the upper die 30 and the lower die 21 (both of these structures are existing conventional structures and will not be elaborated here). They can melt the rubber material and place it in the cavity between the upper die 30 and the lower die 21 to achieve molding. Generally, after a few seconds, the heating device stops heating. Then, the water flowing through the cold runner device can cool it;

[0035] Then, the push rod of the upper pressing oil cylinder 17 retracts, and the upper die 30 is separated from the lower die 21. The upper die 30 is provided with air blowing holes. An upper connection through hole is formed on the upper pressing block 18 corresponding to the air blowing holes. The upper connection through hole communicates with the corresponding air blowing holes. The top surface of the upper pressing block 18 at the top end of the upper connection through hole can be connected to a connector. The connector is connected to an air blowing pipe, and the air blowing pipe is connected to the air outlet end of the control valve of the pneumatic system. By operating the control valve, air blowing is realized. When the upper die 30 is lifted, the molded material is blown, so that the long rubber part and the connected edge material are on the lower die 21. By pushing the push rods of the two pushing oil cylinders 40, the bottom die moving plate 20 is moved leftward to the leftmost end. At this time, it can be manually removed very conveniently. Then, new rubber material can be placed. It has a high degree of automation and good use effect.
