[0001] The utility model relates to the technical field of injection molds, in particular to a rapid demoulding device for injection molds. Background Art

[0002] As a processing technology, injection mold has gone through many years of development. With the advancement of science and technology and the continuous improvement of technology, the design, manufacturing and use of injection molds have been significantly improved.

[0003] Currently, in the existing technology, a Chinese patent with announcement number CN216373144U discloses a steel injection mold with automatic discharge. The device is provided with a frame, support rods, cylinders, connecting plates, upper molds, lower molds, connecting rods, worms, top plates, fixing frames, motors and worm gears, which facilitates people to remove the die-cast industrial parts from the lower mold, avoiding the tedious operation of manually removing the parts. However, in actual use, the device has a long demolding time, which directly leads to a decrease in production efficiency, increases production costs, causes stagnation of the production line, and affects the overall production progress. In view of this, we propose a rapid demolding device for injection molds. Utility Model Content

[0006] Fixed rods, the connecting plate is fixedly connected to fixed rods, and two groups of fixed rods are provided;

[0007] A clamping assembly is provided on the fixing rod, and a communicating hole is provided on the surface of the supporting platform;

[0008] The lifting plate, the fixing rod is clamped with the lifting plate through a clamping assembly, and the lifting plate is fixedly connected with a stripping plate, and the stripping plate is arranged just below the recess.

[0009] Preferably, the clamping assembly includes a clearance groove, and the outer wall of the fixing rod is provided with a clearance groove.

[0010] Preferably, a limiting rod is fixedly connected in the clearance groove, and a fixing column is fixedly connected to the lifting plate. The setting of the clearance groove facilitates the adjustment of the clamping assembly, and the fixing column can be clamped.

[0011] Preferably, an elastic block is fixedly connected to the fixing column, and the elastic block is provided in multiple groups. The elastic block is freed from limit when it is unfolded, and a snap-fit position is left in the middle when the elastic block is closed.

[0012] Preferably, the outer wall of the fixed column is fixedly connected to a limit ring, and the limit ring is elastically connected to the sliding cylinder through a reset spring. The limit ring limits the movement of the sliding cylinder and serves as a fixed point of one end of the reset spring. When the sliding cylinder is pulled downward by an external force, the reset spring is compressed and stores elastic potential energy, and the retracted elastic block is released from the limit and opened. When the external force is released, the reset spring will release energy and push the sliding cylinder to reset upward.

[0013] Preferably, the sliding cylinder is sleeved on the outside of the elastic block.

[0014] The utility model provides a rapid demoulding device for injection molds, which has the following beneficial effects:

[0015] (1) The rapid demoulding device of the injection mold is provided with a rapid demoulding device. When the piston rod of the cylinder drives the upper module to move downward, the connecting plate drives the fixed rod to move downward immediately. When the upper module performs the injection molding task, the fixed rod enters the interior of the support platform through the connecting hole. The fixed rod is clamped with the lifting plate through the clamping assembly, driving the demoulding plate to rise. After the injection molding is completed, the mold is lifted from the recessed position through the demoulding plate to push the product out, shortening the production cycle and reducing the residence time in the mold.

[0016] (2) The quick demoulding device of the injection mold is provided with a clamping assembly, which squeezes the sliding cylinder through the fixed rod. The reset spring is compressed and stores elastic potential energy, and the retracted elastic block is released from the limit and opened. The opened elastic block contacts the limit rod through the clearance groove. After the injection task is completed, the pressure is released, the reset spring will release energy, and push the sliding cylinder to reset upward. At this time, the elastic block closes and clamps the limit rod, which speeds up the flexibility in work and improves the linkage effect of work. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-Figure 5 The present invention proposes a rapid demoulding device for an injection mold, comprising a support platform 1, a support frame 2 being fixedly connected above the support platform 1, a cylinder 3 being provided on the support frame 2, a piston rod of the cylinder 3 being fixedly connected to an upper module 4, a connecting plate 401 being slidably connected to the support platform 1, and a lower module 5 being fixedly connected to the support platform 1, the above-mentioned cylinder 3, upper module 4 and lower module 5 are similar in principle to those mentioned in the Chinese patent with authorization announcement number CN216373144U (a steel injection mold with automatic discharge), and the same effect is achieved, which is an existing public technical means in this field and will not be elaborated here. A recess 501 is provided on the surface of the lower module 5, and a rapid demoulding device 6 is provided on the connecting plate 401, and the rapid demoulding device 6 includes a fixing rod 61.

[0028] In the embodiment of the present invention, in order to shorten the production cycle, reduce the residence time in the mold, and improve the use effect of the subsequent rapid demoulding device 6, specifically, a fixing rod 61 is fixedly connected to the connecting plate 401, and the fixing rod 61 is provided with two groups. When the piston rod of the cylinder 3 drives the upper module 4 to move downward, the connecting plate 401 drives the fixing rod 61 to move downward immediately. A clamping assembly 62 is provided on the fixing rod 61, and a connecting hole 63 is provided on the surface of the support platform 1. The fixing rod 61 is longer than the upper module 4. When the upper module 4 performs the injection molding task, the fixing rod 61 enters the interior of the support platform 1 through the connecting hole 63, and the fixing rod 61 squeezes the sliding cylinder 627, and the return spring 626 is compressed and By storing elastic potential energy, the retracted elastic block 624 is released from the limit and opened, and the opened elastic block 624 contacts the limit rod 622 through the clearance groove 621. After the injection molding task is completed, the pressure is released, the reset spring 626 will release energy, and push the sliding cylinder 627 to reset upward. At this time, the elastic block 624 closes to clamp the limit rod 622, and the fixed rod 61 is clamped with the lifting plate 64 through the clamping assembly 62, and the lifting plate 64 is fixedly connected with a stripper plate 65, which is arranged just below the recess 501. As the upper module 4 is forced to move upward, the fixed rod 61 drives the stripper plate 65 to rise, and the mold after injection molding is lifted from the recess 501 through the stripper plate 65 to push the product out.

[0029] In the present invention, when in use, when the piston rod of the cylinder 3 drives the upper module 4 to move downward, the connecting plate 401 drives the fixing rod 61 to move downward immediately. When the upper module 4 performs the injection molding task, the fixing rod 61 enters the interior of the support platform 1 through the connecting hole 63. The fixing rod 61 squeezes the sliding cylinder 627. The sliding cylinder 627 slides on the fixing column 623 under the limit of the limiting ring 625. The retracted elastic block 624 is released from the limit and opened. The opened elastic block 624 contacts the groove 621 through the groove 621. When the upper mold assembly 4 is moved upward by force, the fixed rod 61 drives the stripping plate 65 to rise, and the mold after injection molding is completed is pushed out of the recess 501 through the stripping plate 65 to push the product out. This can shorten the production cycle, reduce the residence time in the mold, and improve the use effect of the subsequent rapid demoulding device 6.
