Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a mold with an anti-retraction slider. Background Art

[0002] During mold production, especially when designing complex product structures, sliders are often used to facilitate molding and demolding. These sliders can slide vertically or at a certain angle during mold opening to facilitate smooth demolding of the product. However, under high-pressure environments, the sliders can easily retreat due to internal pressure, leading to product quality issues such as burrs, flash, and even mold failure.

[0003] For example, the authorization announcement number is: CN202320958961.8. The utility model relates to the technical field of injection molds and discloses an injection mold for convenient unloading, including a base, the top of the base is fixedly connected to a fixed plate, the top of the fixed plate is fixed with a cross plate, the bottom of the cross plate is bolted to an upper mold by a hydraulic rod, the top of the base is fixedly connected to a lower mold, the top of the lower mold is provided with a plurality of through holes, and an ejection structure is provided inside the lower mold, both sides of the back side of the fixed plate are fixedly connected to connecting plates, and a screw is rotatably connected between the two connecting plates, and one side of the connecting plate on the right is fixedly connected to a motor; the utility model can automatically eject the injection-molded injection molded parts, facilitate separation between them and the lower mold, so as to facilitate subsequent material removal operations, and at the same time, the ejected injection molded parts can be pushed, which not only facilitates unloading of the injection molded parts, but also facilitates collection and processing of them by staff.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that after the injection molding of the injection molded parts is completed, the injection molded parts need to be demolded before they can be discharged. The injection mold includes an upper mold and a lower mold. After the demolding is completed, the injection molded parts need to be manually removed from between the upper mold and the lower mold. Since the injection molded parts are easily fitted too tightly with the lower mold, the staff needs to knock them before they can be separated. Such operation method is not only time-consuming and labor-intensive, but also reduces the work efficiency. However, during use, although the injection mold is provided with a device to prevent the slider from retreating, if the user needs to replace a different mold, the injection mold is not provided with a device that facilitates the user to replace different molds. In the meantime, the function of the injection mold is relatively single, which will reduce its practicality. Utility Model Content

[0023] refer to Figure 3 The mounting assembly 14 includes a mounting groove 141, which is opened on both sides of the front and rear top of the inner wall of the fixed block 3. The inner wall of the mounting groove 141 is slidably connected with a mounting block 142, and the inner side of the mounting block 142 is fixedly connected to both sides of the front and back of the lower mold 12.

[0024] As a technical optimization solution of the present invention, by setting up the installation component 14, when the user needs to connect the lower mold 12 with the fixed block 3, the installation blocks 142 on both sides of the lower mold 12 are aligned with the installation groove 141, and then the installation groove 141 is moved downward so that the installation block 142 is completely moved to the inside of the installation groove 141. The installation groove 141 can be used to limit the moving direction of the installation block 142 so that the lower mold 12 is connected to the fixed block 3. When the user needs to replace the lower mold 12, it is only necessary to move the installation block 142 out of the installation groove 141, thereby achieving the effect of making it easy for the user to install the lower mold 12.

[0025] refer to Figure 1 and Figure 2 The connecting assembly 15 includes a connecting block 151, the bottom of the connecting block 151 is fixedly connected to the output end of the telescopic rod 11, a rotating groove 152 is provided at the top of the connecting block 151, and a connecting rod 153 is slidably connected to the inner wall of the rotating groove 152. The top of the connecting rod 153 is fixedly connected to a connecting plate 154, and a connecting groove 155 is provided at the top of the lifting plate 13, and the inner wall of the connecting groove 155 is slidably connected to the surface of the connecting plate 154.

[0026] As a technical optimization solution of the present invention, by setting up a connecting component 15, when the user needs to connect the lifting plate 13 with the lower mold 12, the connecting rod 153 at the bottom of the connecting plate 154 is aligned with the rotating groove 152, and then the connecting plate 154 is moved downward so that the connecting rod 153 is completely moved into the inside of the rotating groove 152. The connecting rod 153 can be connected to the connecting block 151 using the rotating groove 152, so that the telescopic rod 11 moves upward, which will drive the lifting plate 13 to move upward, thereby achieving the effect of making it easy for the user to install the lifting plate 13.

[0027] refer to Figure 2 , both sides of the inner wall of the rotating groove 152 are provided with a card slot 16, the inner wall of the card slot 16 is slidably connected with a card block 17, the top of the card block 17 is fixedly connected to the bottom of the connecting rod 153, and both sides of the inner wall of the card slot 16 are fixedly connected with a magnetic block 18, and the surface of the magnetic block 18 is magnetically adsorbed to both sides of the card block 17.

[0028] As a technical optimization solution of the present invention, by setting the slot 16, the block 17, and the magnetic block 18, when the user moves the connecting rod 153 to the inside of the rotating slot 152, the block 17 will follow the rotating rod 24 to move to the bottom of the inner wall of the slot 16. When the bottom of the block 17 contacts the bottom of the inner wall of the slot 16, the connecting plate 154 is rotated clockwise to make the block 17 contact the magnetic block 18. Since the space at the bottom of the slot 16 is larger than the space at the top, the block 17 can rotate at the bottom of the inner wall of the slot 16, and the block 17 cannot move out of the slot 16 after rotation. The magnetic block 18 can then be used to first adsorb the block 17 inside the slot 16 to prevent the rotating rod 24 from automatically moving out of the rotating slot 152, thereby achieving the effect of restricting the connecting plate 154 from moving out of the connecting block 151.

[0029] refer to Figure 2 A limiting groove 19 is opened on the surface of the connecting plate 154 , and a limiting ring 20 is slidably connected to the inner wall of the limiting groove 19 , and the surface of the limiting ring 20 is fixedly connected to the inner wall of the connecting groove 155 .

[0030] As a technical optimization solution of the present invention, by setting the limiting groove 19 and the limiting ring 20, when the user needs to rotate the connecting plate 154, the limiting ring 20 is fixedly connected to the inside of the connecting groove 155, so that the connecting plate 154 cannot move out of the lifting plate 13, and it is also convenient for the user to rotate the connecting plate 154, thereby achieving the effect of limiting the up and down movement of the connecting plate 154.

[0031] refer to Figure 3 A reinforcement groove 21 is provided at the top of the mounting block 142 and the bottom of the inner wall of the mounting groove 141 , and a reinforcement rod 22 is threadedly connected to the inner wall of the reinforcement groove 21 .

[0032] As a technical optimization solution of the present invention, by setting a reinforcement groove 21 and a reinforcement rod 22, when the user moves the mounting block 142 completely to the inside of the mounting groove 141, the reinforcement groove 21 on the mounting block 142 is aligned with the reinforcement groove 21 at the bottom of the inner wall of the mounting groove 141, and then the reinforcement rod 22 is aligned with the reinforcement groove 21. At this time, the reinforcement rod 22 is rotated to make the reinforcement rod 22 completely move to the inside of the reinforcement groove 21. The mounting block 142 can be connected to the fixed block 3 by using the reinforcement rod 22, thereby making it difficult for the lower mold 12 to automatically detach from the fixed block 3, thereby achieving the effect of reinforcing the installation of the lower mold 12.

[0033] refer to Figure 3 A through slot 23 is provided at the top of the reinforcing rod 22 , and a rotating rod 24 is slidably connected to the inner wall of the through slot 23 .

[0034] As a technical optimization solution of the present invention, by setting the through groove 23 and the rotating rod 24, when the user needs to replace the lower mold 12, the bottom of the surface of the rotating rod 24 is aligned with the through groove 23, and then the rotating rod 24 is moved downward so that the bottom of the surface of the rotating rod 24 is completely connected with the bottom of the surface of the rotating rod 24. The through groove 23 can be used to limit the moving direction of the rotating rod 24, so that when the rotating rod 24 rotates, it will drive the reinforcement rod 22 to rotate, and then the reinforcement rod 22 can be separated from the reinforcement groove 21, thereby achieving the effect of making it easy for the user to disassemble the lower mold 12.

[0035] The working principle and usage process of the utility model are as follows: when the user needs to take out the object inside the lower mold 12, the telescopic rod 11 is opened, and the output end of the telescopic rod 11 is moved upward to drive the lifting plate 13 to move upward. The lifting plate 13 can drive the object inside the lower mold 12 to move upward, which is convenient for the user to move the object later. When the user needs to connect the lower mold 12 with the fixed block 3, the mounting blocks 142 on both sides of the lower mold 12 are aligned with the mounting grooves 141, and then the mounting grooves 141 are moved downward so that the mounting blocks 142 are completely moved into the interior of the mounting grooves 141. The mounting grooves 141 can be used to limit the movement of the mounting blocks 142 direction, so that the lower mold 12 is connected to the fixed block 3. When the user needs to replace the lower mold 12, it is only necessary to move the mounting block 142 out of the mounting groove 141. When the user needs to connect the lifting plate 13 to the lower mold 12, the connecting rod 153 at the bottom of the connecting plate 154 is aligned with the rotating groove 152, and then the connecting plate 154 is moved downward so that the connecting rod 153 is completely moved to the inside of the rotating groove 152. The connecting rod 153 can be connected to the connecting block 151 using the rotating groove 152. When the bottom of the block 17 contacts the bottom of the inner wall of the slot 16, the connecting plate 154 is rotated clockwise to connect the block 17 to the magnetic block 18. Since the space at the bottom of the card slot 16 is larger than the space at the top, the card block 17 can rotate at the bottom of the inner wall of the card slot 16, and the card block 17 cannot move out of the card slot 16 after rotation. The magnetic block 18 can then be used to adsorb the card block 17 inside the card slot 16 to prevent the rotating rod 24 from automatically moving out of the rotating slot 152. The rotating slot 152 can be used to connect the connecting rod 153 and the connecting block 151 together, so that the telescopic rod 11 moves upward, which will drive the lifting plate 13 to move upward. When the user moves the mounting block 142 completely to the inside of the mounting slot 141, the reinforcement groove 21 on the mounting block 142 and the bottom of the inner wall of the mounting slot 141 are in contact with each other. The reinforcement groove 21 is aligned, and then the reinforcement rod 22 is aligned with the reinforcement groove 21. At this time, the reinforcement rod 22 is rotated so that the reinforcement rod 22 is completely moved into the inside of the reinforcement groove 21. The reinforcement rod 22 can be used to connect the mounting block 142 with the fixed block 3, thereby making it difficult for the lower mold 12 to automatically separate from the fixed block 3. After the object in the lower mold 12 is pushed out, the screw 10 is rotated again. The screw 10 rotates while the slider 9 cannot move, so that the slider 9 moves back and forth. The slider 9 can be used to push the object elsewhere. At the same time, the screw 10 can limit the moving direction of the slider 9, so that the slider 9 does not move automatically, thereby achieving the effect of making it easy for users to replace molds.

[0036] To sum up: the mold with a slider that prevents retreat is equipped with a lifting plate 13. When the user needs to take out the object inside the lower mold 12, the telescopic rod 11 is opened and the output end of the telescopic rod 11 is moved upward, which can drive the lifting plate 13 to move upward. The lifting plate 13 can drive the object inside the lower mold 12 to move upward, making it convenient for the user to move the object later. This solves the problem that although the injection mold is equipped with a device to prevent the slider from retreating, if the user needs to change to a different mold, the injection mold is not equipped with a device that facilitates the user to change to a different mold. In this case, the function of the injection mold is relatively single, which will reduce its practicality.
