Description

Technical Field

[0001] This utility model relates to the technical field of mold demolding, specifically a mold demolding mechanism. Background Technology

[0002] A mold is a tool used to process an object by changing the physical state of the material. When a product is formed using a mold, it is usually placed inside the mold cavity and is not easy to remove. Therefore, a corresponding demolding structure can be set to help remove the product from the mold cavity.

[0003] As disclosed in announcement number CN210477678U, a mold demolding structure includes a fixed mold mounting plate, a moving mold mounting plate, an ejector pin base plate, and an ejector pin plate. The fixed mold mounting plate is provided with a fixed mold core, the moving mold mounting plate is provided with a moving mold insert, and the ejector pin plate is provided with a push rod passing through the moving mold insert, with a push block on the push rod. The moving mold mounting plate is also provided with a slider, a first inclined ejector block, a second inclined ejector block passing through the interior of the slider, and a fixed guide block limiting the movement direction of the second inclined ejector block. The first inclined ejector block is connected to the ejector pin plate through an inclined ejector rod. The first inclined ejector block, the second inclined ejector block, the moving mold insert, and the fixed mold core form a product molding cavity. The slider is connected to a driving device. Compared with the use of a shrinking structure, the inclined ejector is pulled inward through an external driving device, separating the two different snap-fit ​​positions into two inclined ejector demoldings, resulting in a very short core-pulling distance, a simpler mold structure, and easier maintenance and stability maintenance.

[0004] However, existing technologies have problems such as overly complex demolding mechanisms, high operating costs, and inconvenient and difficult repositioning operations after demolding the product. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a mold release mechanism. Utility Model Content

[0006] The purpose of this utility model is to provide a demolding mechanism for molds, so as to solve the problems mentioned in the background art that the demolding mechanism is too complex, has a high cost, and is inconvenient and difficult to operate after demolding the product.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mold release mechanism, comprising a lower mold, a fixed support, and an upper mold;

[0008] Also includes:

[0009] The bottom of the lower mold has a through groove, and an ejector plate is installed through the through groove. The upper end of the ejector plate is flush with the inner wall of the bottom of the lower mold.

[0010] A connecting mechanism is provided at the lower end of the top plate and consists of a connecting block, a connecting plate, a movable plate, and a pull ring. The connecting mechanism drives the top plate to form a lifting structure in the through groove.

[0011] Preferably, the lower end of the lower mold is provided with a fixed bracket for support, and the rear side of the upper end of the lower mold is fixedly connected with a fixed rod in a vertical position.

[0012] Preferably, a movable block is fixedly connected to the rear end of the upper mold, and the movable block and the fixed rod form an up-and-down sliding structure. An installation block is fixedly connected to the middle of the upper end of the upper mold, and the installation block is connected to an external driving device.

[0013] Preferably, connecting blocks are fixedly connected to both the left and right sides of the rear end of the ejector plate, and the connecting blocks and the connecting plate form a sliding structure. The inner side of the connecting plate fits with the rear end of the ejector plate, and a movable plate is fixedly connected to the front end of the connecting plate.

[0014] The front end of the movable plate is fixedly connected with a pull ring.

[0015] Preferably, a movable column is fixedly connected to the lower end of the front side of the ejector plate, and the movable column and the auxiliary plate form an up-and-down sliding structure, and the auxiliary plate is fixedly connected to the lower end of the lower mold.

[0016] Meanwhile, a movable plate is provided through the lower end of the auxiliary plate.

[0017] Preferably, the front side of the movable plate and the front plate form a front-to-back sliding structure, and a spring is provided between the rear end of the front plate and the movable plate. The front plate is fixedly connected to the front side of the upper end of the fixed bracket.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The mold uses a demolding mechanism. During the lifting and lowering process, the upper mold drives the movable block and the fixed rod to slide up and down, thereby improving the stability of the upper mold and preventing displacement. When demolding is required, simply pull the pull ring. Together with the movable plate, connecting plate and connecting block, the ejector plate can be driven to extend and retract in the through groove, thereby automatically ejecting the product from the lower mold and achieving the effect of demolding and material removal. Moreover, after demolding is completed, simply release the pull ring. Through the reset action of the spring, the ejector plate can be directly driven to move downward to reset. The structure is simple and reliable, and the cost of use is low.

[0019] 1. It is equipped with a movable block and a mounting block. The upper mold drives the movable block to slide up and down with the fixed rod, thereby preventing the upper mold from shifting during the lifting process and improving the stability of the upper mold during the movement.

[0020] 2. It is equipped with an ejector plate and a connecting mechanism. The connecting mechanism includes a connecting block, a connecting plate, a movable plate and a pull ring. The connecting mechanism can drive the ejector plate to extend and retract in the through groove, so that the product can be directly ejected from the lower mold to achieve demolding.

[0021] 3. It is equipped with a front plate and a spring. The movable plate slides between the front plate and the movable plate. After demolding, the spring restores its elastic deformation and the ejector plate can be directly driven to move downward to reset by the movable plate, connecting plate and connecting block.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-8 The present invention provides the following technical solution.

[0033] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a mold release mechanism comprising a lower mold 1, a fixed support 2, a fixed rod 3, an upper mold 4, a movable block 5, and a mounting block 6. The lower end of the lower mold 1 is provided with a fixed support 2 for support, and a vertically positioned fixed rod 3 is fixedly connected to the rear side of the upper end of the lower mold 1. The rear end of the upper mold 4 is fixedly connected with the movable block 5, and the movable block 5 and the fixed rod 3 form a sliding structure. The middle part of the upper end of the upper mold 4 is fixedly connected with the mounting block 6, and the mounting block 6 is connected to an external driving device. Figure 1 and Figure 5 As shown, the raw material is placed in the lower mold 1, and then the upper mold 4 is moved downward by the external drive device along with the mounting block 6 to form the raw material. The upper mold 4 also drives the movable block 5 to slide between the fixed rod 3, thereby improving the stability of the upper mold 4 during the lifting and moving process and preventing deviation.

[0034] Example 2: To address the problems of overly complex demolding mechanisms, high operating costs, and inconvenient repositioning operations after product demolding in existing technologies, this example provides a demolding mechanism for a mold, comprising a through groove 7, an ejector plate 8, and a connecting mechanism 9. The bottom of the lower mold 1 has a through groove 7, through which the ejector plate 8 is inserted. The upper end of the ejector plate 8 is flush with the inner wall of the bottom of the lower mold 1. The left and right sides of the rear end of the ejector plate 8 are fixed... A connecting block 10 is fixedly connected, and the connecting block 10 and the connecting plate 11 form a sliding structure. The inner side of the connecting plate 11 fits with the rear end of the ejector plate 8, and a movable plate 12 is fixedly connected to the front end of the connecting plate 11. A pull ring 13 is fixedly connected to the front end of the movable plate 12. A movable column 14 is fixedly connected to the lower end of the front side of the ejector plate 8, and the movable column 14 and the auxiliary plate 15 form an up-and-down sliding structure. The auxiliary plate 15 is fixedly connected to the lower end of the lower mold 1, and the movable plate 12 is provided through the lower end of the auxiliary plate 15. Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, after molding is completed, the upper mold 4 moves upward and separates from the lower mold 1. Then, by pulling the pull ring 13 forward, the pull ring 13 drives the movable plate 12 to move forward. The movable plate 12 compresses the spring 17, causing the spring 17 to undergo elastic deformation. At this time, the movable plate 12 drives the connecting plate 11 to move. The connecting plate 11 slides between itself and the connecting block 10. The connecting plate 11 pushes the ejector plate 8 to move upward. The ejector plate 8 rises and falls in the through groove 7. By moving the ejector plate 8 upward, the ejector plate 8 drives the movable column 14 to slide between itself and the auxiliary plate 15, improving the stability of the ejector plate 8 during the rising and falling process. This allows the molded product in the lower mold 1 to be ejected upward directly, facilitating demolding and allowing the product to be taken out directly.

[0035] Example 3: To solve the problems existing in the prior art, this example provides the following technical solution: a mold ejection mechanism, comprising a movable column 14, an auxiliary plate 15, a front plate 16, and a spring 17. The movable column 14 is fixedly connected to the lower end of the front side of the ejector plate 8, and the movable column 14 and the auxiliary plate 15 form an up-and-down sliding structure. The auxiliary plate 15 is fixedly connected to the lower end of the lower mold 1, and a movable plate 12 is provided through the lower end of the auxiliary plate 15. The front side of the movable plate 12 and the front plate 16 form a back-and-forth sliding structure, and a spring 17 is provided between the rear end of the front plate 16 and the movable plate 12. The front plate 16 is fixedly connected to the front side of the upper end of the fixed bracket 2. Figure 1 , Figure 7 and Figure 8 As shown, after demolding, the operator directly releases the pull ring 13. At this time, as the spring 17 recovers its elastic deformation, it pushes the movable plate 12 to slide between the auxiliary plate 15 and the front plate 16. The movable plate 12 moves forward, and together with the connecting plate 11 and the connecting block 10, it drives the ejector plate 8 to move downward to reset. The overall structural design is very simple and reliable, and the cost of use is low.
