Description

Technical Field

[0001] This invention relates to a demolding device, which is suitable for demolding equipment in filter core processing production lines. Background Technology

[0002] A filter cartridge is a filtration device and the core component of a filter. Filter cartridges separate solid particles from liquids or gases, or allow different substances to come into full contact, accelerating reaction time. They protect the normal operation of equipment and ensure air cleanliness. When fluid enters a filter cartridge containing a filter screen of a specific size, impurities are blocked, while clean fluid flows out through the cartridge. Filter cartridges purify contaminated fluids to the state required for production and daily life, and are applicable to various fields such as medicine, food, and chemicals.

[0003] In existing filter cartridge dispensing production lines, molds are installed at both ends of the filter cartridge after dispensing. After the adhesive solidifies, the molds are removed to obtain the finished product. Currently, the removal of filter cartridge molds mostly relies on robotic arms or manual demolding. However, this method incurs significant production costs, and the excessively long processing time reduces efficiency. Furthermore, due to the small size of the molds and the fragility of the products, robotic arms and other devices struggle to accurately hold the molds, potentially damaging the products and reducing yield, thus negatively impacting the company's production efficiency. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention proposes a demolding device.

[0005] The technical solution adopted in this invention is: a demolding device for detaching the molds at both ends of a product from the product, wherein the product refers to a filter element. This device includes a clamping mechanism for clamping the product, a driving mechanism for moving the clamping mechanism in a front-to-back direction, and demolding guide rails respectively disposed on the left and right sides of the clamping mechanism and extending in a front-to-back direction. Each demolding guide rail has a first mold guide groove on its upper surface along its extension direction for mold embedding. The first mold guide grooves are inclined from front to back away from the clamping mechanism, and the two first mold guide grooves extend backward in a dovetail shape. When the clamping mechanism clamps the product, the driving mechanism drives the clamping mechanism to move backward. The mold embedded in the first mold guide grooves gradually moves away from the clamping mechanism under the guidance of the first mold guide grooves, and thus detaches from the product, achieving automated demolding.

[0006] Furthermore, the clamping mechanism includes a lower support frame, an upper support frame disposed above the lower support frame, and an upper clamping block and a lower clamping block respectively disposed between the upper support frame and the lower support frame that can move up and down. The upper support frame and the lower support frame are respectively fixedly connected with a drive component for driving the upper clamping block and the lower clamping block to move so that the upper clamping block and the lower clamping block move closer to each other or further away from each other, so as to facilitate driving the upper clamping block and the lower clamping block to clamp or release the product.

[0007] Furthermore, the bottom surface of the upper clamping block has at least one first clamping cavity that extends through the upper clamping block in the left-right direction, and the top surface of the lower clamping block has a number and position of second clamping cavities that correspond one-to-one with the first clamping cavities. The second clamping cavities extend through the lower clamping block in the left-right direction. When the upper and lower clamping blocks approach each other, the corresponding first and second clamping cavities combine to form a cylindrical cavity. The clamping cavities can prevent the product from being damaged by pressure while clamping the product, and the cylindrical circumferential cavity also makes the clamping state more stable.

[0008] Furthermore, there are at least two first clamping cavities arranged in the front-to-back direction, and at least two second clamping cavities arranged in the front-to-back direction. The arrangement of multiple clamping cavities allows for the simultaneous processing of multiple products, thereby improving processing efficiency.

[0009] Furthermore, an auxiliary guide rail parallel to the demolding guide rail is provided above the demolding guide rail. The lower surface of the auxiliary guide rail is provided with a second mold guide groove for the mold to be embedded. The number, position and direction of the second mold guide groove correspond one-to-one with the first mold guide groove. By limiting and guiding the mold from both the top and bottom directions, problems such as incomplete demolding and product tearing damage that are prone to occur in unidirectional demolding are prevented, thereby improving the stability of the demolding process. At the same time, the bidirectional guide groove can guide the direction of the mold after demolding, making it easy to collect and reuse.

[0010] Furthermore, the clamping mechanism is slidably connected to the demolding guide rail and the auxiliary guide rail, making the movement of the clamping mechanism in the front and back directions more stable and improving the stability of the demolding process.

[0011] Furthermore, each demolding guide rail has a third mold guide groove on its upper surface for mold insertion. The third mold guide groove is set parallel to the moving direction of the clamping mechanism. The rear end of the third mold guide groove on the same demolding guide rail is connected to the front end of the first mold guide groove. The parallel third mold guide groove facilitates the smooth delivery of the product to the demolding device and makes the process of the mold entering the first mold guide groove smoother during demolding.

[0012] Furthermore, each demolding guide rail has a third mold guide groove on its upper surface for mold insertion. The third mold guide groove is set parallel to the moving direction of the clamping mechanism. The rear end of the third mold guide groove on the same demolding guide rail is connected to the front end of the first demolding guide rail. The length of the third mold guide groove is greater than or equal to the distance between the frontmost cylindrical cavity and the rearmost cylindrical cavity, so that the product can be smoothly clamped by the clamping device after entering the demolding device.

[0013] Furthermore, an auxiliary guide rail is provided above the demolding guide rail, parallel to the demolding guide rail. The lower surface of the auxiliary guide rail is provided with a second mold guide groove for mold insertion. The number, position and direction of the second mold guide groove correspond one-to-one with the first mold guide groove. The lower surface of each auxiliary guide rail is also provided with a fourth mold guide groove for mold insertion. The fourth mold guide groove is set parallel to the moving direction of the clamping mechanism. The rear end of the fourth mold guide groove on the same auxiliary guide rail is connected to the front end of the second mold guide groove, making the process of mold entering the second mold guide groove smoother.

[0014] Furthermore, the length and position of the fourth mold guide groove correspond one-to-one with the third mold guide groove.

[0015] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0016] The present invention discloses a demolding device that, through two first mold guide grooves extending backward in a dovetail shape on a demolding guide rail, and a second mold guide groove located above and corresponding to the first mold guide grooves, in conjunction with a clamping mechanism that clamps and pushes the product backward, achieves automated demolding of the product, eliminating the large costs associated with manual or robotic arm operations. At the same time, the simple and quick demolding process also improves processing efficiency. The clamping cavity provided on the clamping block can fit against the product surface, ensuring a stable clamping state of the product while preventing damage to the product, thereby improving the product yield and bringing higher benefits to the enterprise.

It includes a clamping mechanism 1 for clamping the product, a driving mechanism (not shown in the figure) for driving the clamping mechanism 1 to move in the front-back direction, and demolding guide rails 2 respectively arranged on the left and right sides of the clamping mechanism 1 and extending in the front-back direction.

[0024] Each demolding guide rail 2 has a first mold guide groove 21 on its upper surface along its extension direction for mold insertion. The first mold guide groove 21 is inclined from front to back away from the clamping mechanism 1. The two first mold guide grooves 21 extend backward in a dovetail shape to facilitate mold positioning and guidance. An auxiliary guide rail 3 is provided above the demolding guide rail 2, parallel to the demolding guide rail 2. The lower surface of the auxiliary guide rail 3 has a second mold guide groove 31 for mold insertion. The number, position, and direction of the second mold guide grooves 31 correspond one-to-one with the first mold guide grooves 21.

[0025] The clamping mechanism 1 includes a lower support frame 11, an upper support frame 12 disposed above the lower support frame 11, and an upper clamping block 13 and a lower clamping block 14 respectively movably disposed between the upper support frame 12 and the lower support frame 11. A drive assembly 15 is fixedly connected to the upper support frame 12 and the lower support frame 11 to drive the upper clamping block 13 and the lower clamping block 14 to move closer to or further away from each other. The bottom surface of the upper clamping block 13 has at least one first clamping cavity 131 that extends through the upper clamping block 13 in the left-right direction. The top surface of the lower clamping block 14 has second clamping cavities 141, each corresponding in number and position to the first clamping cavities 131. The second clamping cavities 141 extend through the lower clamping block 14 in the left-right direction. When the upper clamping block 13 and the lower clamping block 14 approach each other, the corresponding first clamping cavities 131 and second clamping cavities 141 combine to form a cylindrical cavity.

[0026] In a more preferred embodiment, there are at least two first clamping cavities 131 arranged in the front-back direction, and at least two second clamping cavities 141 arranged in the front-back direction.

[0027] In a more preferred embodiment, the clamping mechanism 1 is slidably connected to the demolding guide rail 2 and the auxiliary guide rail 3, respectively.

[0028] In a more preferred embodiment, each demolding guide rail 2 is further provided with a third mold guide groove 22 for mold embedding on its upper surface. The third mold guide groove 22 is arranged parallel to the moving direction of the clamping mechanism 1. The rear end of the third mold guide groove 22 on the same demolding guide rail 2 is connected to the front end of the first demolding guide rail 2. The length of the third mold guide groove 22 is greater than or equal to the distance between the foremost cylindrical cavity and the rearmost cylindrical cavity.

[0029] In a more preferred embodiment, each auxiliary guide rail 3 has a fourth mold guide groove (not shown in the figures) on its lower surface for mold insertion. The fourth mold guide groove is arranged parallel to the moving direction of the clamping mechanism 1, and the rear end of the fourth mold guide groove on the same auxiliary guide rail 3 is connected to the front end of the second mold guide groove 31. The length and position of the fourth mold guide groove correspond one-to-one with the third mold guide groove 22.

[0030] Working principle and process: When the demolding device is in its initial state, the clamping mechanism 1 is at the foremost part of the demolding guide rail 2, with the upper clamping block 13 and the lower clamping block 14 far apart from each other. When the product is conveyed from the previous process to the demolding device, the upper and lower parts of the molds at both ends of the product are respectively embedded in the fourth mold guide groove and the third mold guide groove 22, and roll along the fourth mold guide groove and the third mold guide groove 22 to between the upper clamping block 13 and the lower clamping block 14. Subsequently, the upper clamping block 13 and the lower clamping block 14 move closer to each other under the drive of the drive assembly 15, bringing the product into the first clamping cavity 131 and the second clamping cavity 141 and keeping it clamped. Then the drive mechanism drives the clamping mechanism to move backward, while simultaneously causing the mold to slide into the first mold guide groove 21 and the second mold guide groove 31. The first mold guide groove 21 and the second mold guide groove 31, which extend in a dovetail shape respectively, guide the mold to gradually move away from the clamping mechanism 1, and then detach from the product, completing the automatic demolding. After demolding is completed, the upper clamping block 13 and the lower clamping block 14 move away from each other, releasing the product. The clamping mechanism 1 returns to the front of the demolding guide rail 2 to perform the next demolding operation.
