Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-7, the present invention provides a technical solution:
example 1:
a connecting rod structure for an automatic locking mold of a door body foaming mold frame 1 is shown in figure 1, the mold frame 1 is divided into an upper layer and a lower layer, meanwhile, the mold frames 1 of the upper layer and the lower layer are fixedly and tightly squeezed through T-shaped abutting blocks 12 connected by a pressure rod 2, in a specific operation, in order to integrally lock the upper mold frame 1 and the lower mold frame 1, a rotating rod 4 is fixed on the pressure rod 2, on one hand, in order to improve the locking speed of the upper mold frame 1 and the lower mold frame 1, the uniform deformation of polyurethane foaming materials is facilitated, and the phenomenon that as workers lock the mold frames 1 one by one for a long time, the partially expanded polyurethane foaming materials overflow from one side which is not locked, and the production of integral foaming products is influenced is prevented; meanwhile, the installation of the pressure lever 2 is beneficial to fixing the whole locking connecting rod structure on a mechanical device, the automatic locking of the die carrier 1 can be realized by pulling the mechanical device, the degree of automation is high, and meanwhile, the operation of workers is facilitated;
during specific operation, 6 fixing grooves 16 are uniformly formed in a cross beam of a die carrier 1, meanwhile, a threaded column 10 is arranged at the bottom of each fixing groove 16, the thread pitch of each threaded column 10 is 2mm, each threaded column 10 is connected with a rotating rod 4 through a rotating shaft 14, each rotating rod 4 is connected with a press rod 2 through a clamping column 3, when the press rod 2 drives each rotating rod 4 to rotate 90 degrees, each threaded column 10 in the die carrier 1 rises by 0.5mm, the threaded columns 10 are connected with T-shaped abutting blocks 12, the T-shaped abutting blocks 12 in the upper die carrier 1 are in an initial state and are parallel to longitudinal beams in the upper die carrier 1, when the rotating rods 4 rotate 90 degrees, the rotating rods 4 drive the rotating shafts 14 and the threaded columns 10 to rotate, so that the T-shaped abutting blocks 12 at the bottom of the upper die carrier 1 rotate 90 degrees, meanwhile, the threaded columns 10 rotate and rise by 0.5mm in the die carrier 1, the longitudinal T-shaped abutting blocks 12 are changed into a transverse direction, and the T-shaped abutting blocks 12 are clamped with notches in the lower die carrier 1, the lower die carrier 1 is driven to rise by 0.5mm while clamping is carried out, so that the clamping between the upper die carrier 1 and the lower die carrier 1 is firmer;
the circular pressing plate 9 and the rubber pad 13 which are arranged on the rotating shaft 14 are used for sharing the pressure which is applied to the rotating shaft 14 by the die carrier 1, so that the phenomenon that the threaded column 10 is clamped into the die carrier 1 due to the fact that the upper die carrier 1 and the lower die carrier 1 are pressed too tightly is avoided, the cushion cover 11 which is positioned on the T-shaped abutting block 12 at the bottom of the threaded column 10 is used for protecting the T-shaped abutting block 12, and if the T-shaped abutting block 12 is directly contacted with the other half of the die carrier 1, the T-shaped abutting block 12 is easy to deform due to direct contact of steel materials between the die carrier 1 and the die carrier 1, and the clamping effect of the die carrier 1 is reduced;
as shown in fig. 5, when the mechanical device pulls the press rod 2 to move, the rotation rod 4 drives the threaded column 10 to rotate, and at the same time, the threaded column 10 has a small-amplitude 0.5mm rise, and if the external mechanical structure is pulled directly and is rigidly connected with the press rod 2, the threaded column 10 is deformed by force and is blocked in the die carrier 1.
Example 2:
in order to make the rotating rod 4 driven by the pressure rod 2 more stable after locking and avoid the T-shaped abutting block 12 from falling off the die carrier 1 due to the vibration of the die carrier 1, the pressure rod 2 is fixed at the moment, a buckle 17 is arranged on one side of the pressure rod 2, when the rotating rod 4 in the chute 5 rotates 90 degrees, the buckle 17 arranged at one end of the pressure rod 2 approaches to one side of the die carrier 1, the buckle 17 is clamped on the die carrier 1, and a locking block 6 is arranged on the opposite surface of the pressure rod 2 and the die carrier 1, as shown in figures 3-4, the locking block 6 is fixed on the die carrier 1 through spot welding, meanwhile, a fixing hole is arranged on the locking block 6, when the pressure rod 2 is locked, the U-shaped clamping block 7 is arranged on the pressure rod 2, a locking hole 15 is also arranged on the U-shaped clamping block 7, a locking bolt 8 can be directly turned into the locking hole 15, so that the locking bolt 8 can stably fix the pressure rod 2 on the locking block 6, the pressure lever 2 is prevented from moving randomly;
after the lock bolt 8 is completely fixed, the connecting rod structure of the automatic locking mold of the whole door foaming mold frame 1 is installed, and when the door foaming mold frame is disassembled, the press rod 2 is pushed while the lock bolt 8 is disassembled, so that the upper mold frame 1 and the lower mold frame 1 can be separated, and the operation is simple and rapid.
The working process of the invention is as follows:
during the operation, the worker sprays the foaming material on the lower die frame 1 and covers the upper die frame 1 on the lower die frame 1 through the assembling machine, at the moment, the pressure lever 2 on the die frame 1 is pulled by an external mechanical device to drive the rotating rod 4 to rotate, the rotating rod 4 is provided with the sliding groove 5, the clamping column 3 on the pressure lever 2 is clamped with the sliding groove 5 on the rotating rod 4, when the pressure lever 2 moves transversely, the rotating rod 4 drives the rotating shaft 14 on the die carrier 1 to rotate, the threaded column 10 connected with the bottom of the rotating shaft 14 also starts to rotate, the T-shaped abutting block 12 at one end of the threaded column 10 starts to be positioned in the lower die carrier 1, when the T-shaped supporting block 12 is connected with the threaded column 10 and starts to rotate, the T-shaped supporting block 12 also rotates along with the threaded column, the T-shaped supporting block 12 rotates and simultaneously clamps the lower die carrier 1, so that the upper die carrier 1 and the lower die carrier 1 are clamped, the T-shaped abutting block 12 is lifted by 0.5mm when the threaded column 10 rotates, so that the upper die frame 1 and the lower die frame 1 are clamped and fastened;
after the clamping connection between the die carrier 1 is completed, the lock bolt 8 penetrates through the lock hole 15 on the U-shaped fixture block 7, and the lock hole 15 is in butt joint with the fixing hole on the press rod 2, so that the press rod 2 is fixed on the lock block 6 while the lock bolt 8 rotates, and the press rod 2 is prevented from displacing to cause the T-shaped support block 12 to be detached from the die carrier.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
