DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] A preferred embodiment of the quick mold changing device for an injection molding machine provided by the utility model is as follows Figures 1 to 5 As shown: a quick mold changing device for an injection molding machine, comprising a base 1, a support plate 2 is fixedly connected to the top of the base 1, a mounting seat 3 is fixedly connected to the side of the support plate 2, a mold 4 is fitted inside the mounting seat 3, a card slot 5 is opened on the side of the mold 4, an electric push rod 6 is fixedly connected to the bottom of the support plate 2, a control board 7 is fixedly connected to the output end of the electric push rod 6, a transmission block 8 is fixedly connected to the top of the control board 7, a force block 10 is fitted to the bottom of the transmission block 8, a connecting plate 11 embedded in the card slot 5 is fixedly connected to the top of the force block 10, a first spring 12 fixedly connected to the mounting seat 3 is fixedly connected to one side of the connecting plate 11, and a limit rod 13 fixedly connected to the mounting seat 3 is slidably connected inside the connecting plate 11.

[0027] In this embodiment, the mating surfaces of the transmission block 8 and the force block 10 are both inclined, and the transmission block 8 forms a lifting structure through the electric push rod 6. Because the mating surfaces of the transmission block 8 and the force block 10 are both inclined, when the transmission block 8 rises and no longer fits with the force block 10, the force block 10 will drive the connecting plate 11 to slide sideways along the limit rod 13 under the influence of the first spring 12.

[0028] In this embodiment, the limiting rod 13 and the mounting seat 3 are arranged perpendicular to each other. Under the action of the first spring 12, the connecting plate 11 forms a sliding structure along the limiting rod 13. When the connecting plate 11 moves, it will move out of the inside of the card slot 5. At this time, the mold 4 loses the clamping force from the connecting plate 11 and can be taken out from the inside of the mounting seat 3.

[0029] In this embodiment, the connecting plate 11 and the card slot 5 are in a tightly fitted state, and the mold 4 is fixed inside the mounting seat 3 through the connecting plate 11. When the connecting plate 11 is inserted into the card slot 5, there is no gap between the card slot 5 and the connecting plate 11, so that the mold 4 is fixed more stably.

[0030] Example 2

[0031] On the basis of Example 1, a preferred embodiment of a quick mold changing device for an injection molding machine provided by the utility model is as follows: Figures 1 to 5 As shown: the top of the base 1 is slidably connected to a baffle 14 located above the mold 4, the inner wall of the baffle 14 is fixedly connected to a second spring 15 fixedly connected to the support plate 2, fixed grooves 9 are provided on both sides of the baffle 14, the top of the support plate 2 is rotatably connected to a forward and reverse screw rod 16, and the surface of the forward and reverse screw rod 16 is threadedly connected to a block 17 slidably connected to the support plate 2.

[0032] In this embodiment, the mold 4 is located on the movement track of the baffle 14 , and the top of the mold 4 is flush with the bottom of the baffle 14 , so that the bottom of the baffle 14 and the top of the mold 4 can be completely fitted together.

[0033] In this embodiment, the forward and reverse screw rods 16 drive the two groups of blocks 17 to form a synchronous sliding structure, and the baffle 14 forms a fixed structure through the blocks 17. When the forward and reverse screw rods 16 are rotated, the two groups of blocks 17 will be driven away from each other along the top of the support plate 2.

[0034] In this embodiment, the baffle 14 is an "L"-shaped structure. When the block 17 moves out of the fixed groove 9, the baffle 14 forms an automatic sliding structure through the second spring 15. When the two groups of blocks 17 move away from each other, they will slide out of the fixed groove 9. At this time, the baffle 14 is no longer fixed by the block 17, and can automatically slide along the top of the base 1 toward the mold 4 under the elastic force of the second spring 15.

[0035] The working principle and use process of the utility model are as follows: first, when the mold 4 needs to be replaced quickly, it is only necessary to open the electric push rod 6 to control the control plate 7 to move upward, and the transmission block 8 will move accordingly. Because the contact surfaces of the transmission block 8 and the force block 10 are both inclined surfaces, when the transmission block 8 rises and no longer contacts the force block 10, the force block 10 will, under the influence of the first spring 12, drive the connecting plate 11 to slide sideways along the limit rod 13. When the connecting plate 11 moves, it will move out of the inside of the card slot 5. At this time, the mold 4 loses the clamping force from the connecting plate 11 and can be taken out from the inside of the mounting seat 3, thereby realizing the operation of quickly disassembling the mold 4 for mold changing.

[0036] When the device is not in use, the forward and reverse screw rods 16 can be rotated through the shield 14. When the forward and reverse screw rods 16 rotate, the two groups of blocks 17 will be driven to move away from each other along the top of the support plate 2. When the two groups of blocks 17 move away from each other, they will slide out of the fixing groove 9. At this time, the shield 14 is no longer fixed by the blocks 17, and can automatically slide along the top of the base 1 toward the mold 4 under the elastic force of the second spring 15, and slide to the top of the mold 4, covering the top of the mold 4 to prevent dust from falling from the top of the mold 4 into the interior of the mold 4.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
