Technical Field

[0001] The utility model relates to the technical field of core-pulling pad production, in particular to a two-side core-pulling mechanism for the production of core-pulling pads. Background Art

[0002] Core-pulling backing plates are components used in mold manufacturing and molding processes, widely used in the production of plastics, metals, composites, and other industries. Their primary function is to control the flow and cooling of materials during the molding process, ensuring product precision, strength, and surface quality. Core-pulling technology is crucial in mold manufacturing, especially in the production of complex parts, effectively improving the structural integrity and aesthetics of the finished product.

[0003] In the current production of core-pulling pads, the mold pulls the core from one side when pulling the core, so there are the following disadvantages: Although this method is relatively simple, it will also cause great stress in the product, and the influence of stress will cause the performance of the product to be unstable, resulting in a reduction in the service life of the product. Utility Model Content

[0004] The purpose of the utility model is to provide a core-pulling mechanism on both sides for the production of core-pulling pads, so as to solve the problem that although this method is relatively simple, it will also cause great stress in the product, and the influence of stress will cause the performance of the product to be unstable, resulting in a reduction in the service life of the product.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: a core-pulling mechanism on both sides for the production of core-pulling pads, comprising two mounting plates, the two mounting plates being movably arranged on the left and right sides of the pad body, a plurality of core holes being opened on one side of the pad body, a plurality of plate cores being detachably arranged on the inner sides of the two mounting plates, a plurality of the plate cores being slidably inserted into the plurality of core holes, and a connecting rod being detachably arranged on the outer sides of the two mounting plates.

[0006] Preferably, the top and bottom surfaces of the two mounting plates are respectively provided with a first threaded groove, the top and bottom surfaces of the two connecting rods are respectively fixed with a fixing plate, the top surfaces of the two fixing plates are respectively provided with a first threaded hole, the two first threaded holes are respectively threadedly connected with a first bolt, and the threaded ends of the two first bolts are respectively connected to the internal threads of the two first threaded grooves.

[0007] Preferably, positioning blocks are fixed on the inner sides of the two connecting rods respectively, and positioning grooves are respectively opened on the top surfaces of the two mounting plates, and the two positioning grooves respectively position the two positioning blocks.

[0008] Preferably, a second thread groove is respectively opened on the outer side of several of the plate cores, a plurality of second threaded holes are respectively opened on one side of the two mounting plates, a second bolt is respectively threadedly connected in several of the second threaded holes, and the threaded ends of several of the second bolts are respectively threadedly connected to the internal threads of several second thread grooves.

[0009] Preferably, washers are provided between the two first bolts and the two fixing plates respectively.

[0010] Preferably, the thickness of the gasket is 1 cm.

[0011] Compared with the existing technology, the core-pulling mechanism on both sides for producing core-pulling pads using the above technical solution has the following beneficial effects:

[0012] 1. During use, changing the traditional single-side core pulling scheme to core pulling from both sides can reduce or eliminate the stress in the product, avoiding the stress concentration and deformation that may be caused by single-side core pulling, thereby improving product performance and extending product life;

[0013] Second, during use, by rotating the first bolt and utilizing its thread engagement with the first thread groove, workers can easily complete the installation or removal of the connecting rod on the mounting plate, simplifying the assembly and disassembly process, reducing the use of tools, and improving the convenience of operation. When workers install the connecting rod, the positioning block will accurately fall into the corresponding positioning groove, playing a preliminary positioning and guiding role, helping workers to quickly and accurately install the connecting rod and ensuring the stability of the installation;

[0014] 3. During use, when a certain core needs to be replaced or repaired separately, it can be easily disassembled and assembled by simply rotating the corresponding second bolt. This helps to enhance the modularity of the core, facilitates maintenance and management, and ensures that the disassembly and assembly of a single core will not affect the use of other cores, thereby enhancing the flexibility of the production line. The washer helps to increase the contact area between the first bolt and the fixed plate, dispersing the pressure generated when the first bolt is tightened, and preventing the first bolt from loosening or the fixed plate from being damaged. By setting the thickness of the washer to 1cm, this thickness can not only meet the tightening requirements, but also ensure that the washer is not over-compressed during the tightening of the first bolt, affecting the tightening effect.

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a core-pulling mechanism on both sides for producing core-pulling pads comprises two mounting plates 3, which are movably arranged on the left and right sides of the pad body 1, and a plurality of core holes 2 are opened on one side of the pad body 1. A plurality of plate cores 4 are detachably arranged on the inner sides of the two mounting plates 3, and the plurality of plate cores 4 are slidably inserted into the plurality of core holes 2, and a connecting rod 5 is detachably arranged on the outer sides of the two mounting plates 3.

[0022] During use, the staff can pull the two mounting plates 3 outward respectively, and then pull out several plate cores 4 from both sides of the pad body 1 respectively, changing the traditional single-sided core pulling scheme. Pulling the core from both sides can reduce or eliminate the stress in the product, avoiding the stress concentration and deformation that may be caused by single-sided core pulling, so as to improve the performance of the product and increase the service life of the product.

[0023] like Figures 1-4 As shown, the top and bottom surfaces of the two mounting plates 3 are respectively provided with first threaded grooves 6, the top and bottom surfaces of the two connecting rods 5 are respectively fixed with fixing plates 7, the top surfaces of the two fixing plates 7 are respectively provided with first threaded holes 8, and the two first threaded holes 8 are respectively threadedly connected with first bolts 9, and the threaded ends of the two first bolts 9 are respectively threadedly connected to the internal threads of the two first threaded grooves 6.

[0024] During use, by rotating the first bolt 9 and utilizing its thread cooperation with the first thread groove 6, the staff can easily complete the installation or disassembly of the connecting rod 5 on the mounting plate 3, which simplifies the disassembly process, reduces the use of tools, and improves the convenience of operation.

[0025] like Figures 1-4As shown, positioning blocks 10 are respectively fixed on the inner sides of the two connecting rods 5, positioning grooves 11 are respectively provided on the top surfaces of the two mounting plates 3, and the two positioning grooves 11 respectively position the two positioning blocks 10, and second threaded grooves 12 are respectively provided on the outer sides of several plate cores 4, and several second threaded holes 13 are respectively provided on one side of the two mounting plates 3, and second bolts 14 are respectively threadedly connected in several second threaded holes 13, and the threaded ends of several second bolts 14 are respectively threadedly connected to the internal threads of several second threaded grooves 12.

[0026] During use, when a worker installs the connecting rod 5, the positioning block 10 accurately falls into the corresponding positioning slot 11, providing preliminary positioning and guidance, helping the worker quickly and accurately install the connecting rod 5 while ensuring installation stability. When a panel core 4 needs to be replaced or repaired individually, it can be easily disassembled and assembled by simply rotating the corresponding second bolt 14. This enhances the modularity of the panel core 4, facilitating maintenance and management. The disassembly and assembly of a single panel core 4 does not affect the use of other panel cores 4, thereby enhancing the flexibility of the production line.

[0027] like Figures 1-4 As shown, washers 15 are respectively provided between the two first bolts 9 and the two fixing plates 7 , and the thickness of the washers 15 is 1 cm.

[0028] During use, the washer 15 increases the contact area between the first bolt 9 and the fixing plate 7, dissipating the pressure generated when tightening the first bolt 9 and preventing the first bolt 9 from loosening or damaging the fixing plate 7. Setting the thickness of the washer 15 to 1 cm satisfies the tightening requirements while ensuring that the washer 15 is not excessively compressed during the tightening of the first bolt 9, thereby affecting the tightening effect.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
