Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a shaping mold that facilitates template replacement. Background Technology

[0002] Mold technology is a widely used processing technique in modern manufacturing, primarily used for shaping products from various metal or non-metal materials. Forming molds, as a type of mold, are typically used to precisely adjust the shape of workpieces to meet specific dimensional requirements or shape specifications. In traditional forming mold designs, mold replacement usually requires disassembling the entire mold structure, which not only increases the complexity of replacement but also affects production efficiency.

[0003] Existing forming dies have certain limitations in use. First, when processing products of similar size or structure, if it is necessary to change to a different shape of template, the traditional method usually relies on bolts or clamps for fixation, which is cumbersome and can easily affect the accuracy of the mold. Second, because the disassembly and assembly of the template takes a long time, the mold changeover time on the production line is long, thus affecting production efficiency. In addition, if the fixing method is not secure enough during the template change process, the template may shift during use, affecting processing accuracy and product quality. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a shaping mold that facilitates template replacement. It can make the template replacement process more efficient and convenient, while ensuring the stability of the replaced template during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shaping mold that facilitates template replacement includes an upper mold base and a lower mold base. Four evenly distributed guide sleeves are fixed on the upper mold base, and evenly distributed guide pillars are fixed on the upper part of the lower mold base. An upper pad is fixed on the lower surface of the upper mold base, and an upper template is provided on the lower side of the upper pad. A lower pad is fixed on the upper surface of the lower mold base, and a lower template is provided on the upper surface of the lower pad. Locking mechanisms for pressing and fixing the upper template and the lower template are installed on the opposite sides of the upper and lower pads near the left and right sides, respectively.

[0007] The locking mechanism includes an adjusting seat that can be adjusted to the left and right, a downward movable pressure block is installed at the upper end of the adjusting seat, and a clamping screw for adjusting the pressure block downward is installed at the upper end of the adjusting seat.

[0008] Furthermore, the upper surface of the adjusting seat is provided with a mounting groove for installing the pressure block, and the mounting groove is set to open towards the side of the adjusting seat.

[0009] Furthermore, a retaining plate is fixed to the lower end of the adjusting seat, and a locking screw passes through the upper thread of the retaining plate.

[0010] Furthermore, the upper and lower pads have guide slots on their opposite sides near the left and right sides for engaging and guiding the card plate. The guide slots are T-shaped slots.

[0011] Furthermore, one end of the pressure block is fixed with a locking block that is inserted into the locking groove, and the locking block has a countersunk hole in the center.

[0012] Furthermore, positioning grooves are provided on the opposite sides of the upper and lower templates near the left and right ends, and the width of the positioning grooves is the same as the width of the pressure block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Firstly, traditional forming molds require disassembling the entire mold structure when changing the template, resulting in a complex and time-consuming process with low production efficiency. This invention simplifies the template changing process significantly by employing an adjustable locking mechanism and a design for the adjusting seat and pressure block. Operators only need to loosen the locking screws, and the adjusting seat can easily adjust the relative position of the pressure block, enabling rapid template replacement. This structure avoids the cumbersome disassembly steps of traditional molds, reducing the time and manpower required for mold changes, thereby improving the overall efficiency of the production line.

[0015] Secondly, traditional molds are prone to instability or loose fixing when changing templates, affecting processing accuracy and product quality. This invention features a combination of a clamping groove and a clamping block, ensuring the pressure block is firmly fixed within the positioning groove of the upper or lower template, effectively preventing template displacement and loosening during use. Combined with the precise guidance of the clamping plate by the T-shaped guide groove, the pressure block can be pressed more stably, further ensuring template fixing accuracy and improving processing quality.

[0016] Finally, existing molds are prone to inaccurate adjustments when changing templates, leading to template misalignment and affecting workpiece shaping accuracy. This invention addresses this issue by precisely designing the positioning groove and pressure block to ensure accurate template alignment during installation, preventing displacement. Furthermore, the adjustable seat allows for left-right position adjustment, ensuring a tight fit between the template and the mold, thereby improving shaping accuracy and guaranteeing workpiece dimensional consistency and shape accuracy.

[0017] In summary, this utility model not only effectively solves the problems of cumbersome mold replacement process, unstable fixing, and inaccurate adjustment in traditional molds, but also improves the efficiency and accuracy of mold replacement through innovative design, providing greater flexibility and reliability for the production process.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1As shown, a shaping mold with a convenient template replacement includes an upper mold base 2 and a lower mold base 8. Four evenly distributed guide sleeves 1 are fixed on the upper mold base 2. The guide sleeves 1 are generally made of high-strength steel (such as alloy steel or stainless steel, model 45# or 304 material), and their main function is to guide the guide pillars 6 to ensure the stability and accuracy of the mold during operation. Evenly distributed guide pillars 6 are fixed on the lower mold base 8. The guide pillars 6 are made of hard alloy or other wear-resistant materials (such as Cr12MoV material), and their length and diameter should match the guide sleeves 1 on the upper mold base 2 to ensure that the two can be accurately aligned when the mold is closed, thereby avoiding mold deformation and errors. An upper pad 3 is fixed to the lower surface of the upper mold base 2. The upper pad 3 is generally made of steel plate or aluminum alloy, and its thickness is usually between 5mm and 10mm to ensure its strength and stability. An upper template 4 is set on the lower side of the upper pad 3. The upper template 4 is usually made of different mold steel (such as P20 steel or H13 steel) depending on the specific application requirements. Its surface should be hardened to improve wear resistance. A lower pad 7 is fixed to the upper surface of the lower mold base 8. A lower template 5 is set on the upper surface of the lower pad 7. The material of the lower template 5 is similar to that of the upper template 4. It should also be made of a material with high wear resistance and high strength, and usually requires surface strengthening treatment through heat treatment to extend its service life. Locking mechanisms 9 are installed on the opposite sides of the upper pad 3 and the lower pad 7 near the left and right sides to respectively press and fix the upper template 4 and the lower template 5.

[0028] like Figure 2 As shown, the locking mechanism 9 includes an adjusting seat 93 that can be adjusted to the left and right. The adjusting seat 93 is generally made of cast iron or steel, and the surface is sprayed or treated with anti-rust to improve corrosion resistance. A downward movable pressure block 91 is installed at the upper end of the adjusting seat 93. The pressure block 91 is usually made of hardened steel (such as 40Cr steel), and its size should be designed according to the actual shape of the template to ensure that it can stably press the template to prevent loosening during operation. The upper end of the adjusting seat 93 is also equipped with a clamping screw 92 for adjusting the pressure block 91 downward. The clamping screw 92 is usually made of high-strength threaded steel (such as screws in GB / T 5782-2000 standard) to ensure that it does not loosen or get damaged during long-term use.

[0029] like Figure 3 As shown, the upper end face of the adjusting seat 93 is provided with a mounting groove 931 for installing the pressure block 91. The design of the mounting groove 931 is to ensure that the pressure block 91 can be firmly fixed in the mounting groove. The mounting groove 931 is set to open towards the side of the adjusting seat 93. This design makes it easier for operators to adjust and fix the position of the pressure block 91 to adapt to the replacement needs of different templates.

[0030] like Figure 3As shown, a clamping plate 933 is fixed to the lower end of the adjusting seat 93. A locking screw 932 passes through the upper thread of the clamping plate 933. The clamping plate 933 is generally made of cast steel or high-strength alloy steel, and its surface is polished to ensure the stability and wear resistance of the clamping plate 933 during use. The locking screw 932 is fixedly connected to the clamping plate 933 through the adjusting thread, which can effectively and firmly connect the adjusting seat 93 to other components of the mold, preventing loosening during the replacement of the mold template.

[0031] like Figure 4 As shown, guide slots 11 are provided on the opposite sides of the upper pad 3 and the lower pad 7 near the left and right sides to secure and guide the clamping plate 933. The guide slots 11 are T-shaped, which facilitates precise installation and guidance of the clamping plate 933, making it more stable during adjustment and avoiding unnecessary offset or jamming. The size and shape of the guide slots 11 should be designed according to the size of the clamping plate 933 to ensure it can accommodate clamping plates of different specifications.

[0032] like Figure 5 As shown, one end of the pressure block 91 is fixed with a locking block 912 that is locked in the locking groove 931. The locking block 912 is made of high-strength steel and has undergone surface hardening treatment to improve wear resistance. A countersunk hole 911 is provided in the center of the locking block 912. The countersunk hole 911 allows the locking block 912 to better cooperate with the clamping screw 92, thereby improving the clamping effect and ensuring the stability of the template during use.

[0033] like Figure 6 As shown, positioning grooves 10 are provided on the opposite sides of the upper template 4 and the lower template 5 near the left and right ends. The width of the positioning grooves 10 is the same as the width of the pressure block 91. The design of the positioning grooves 10 ensures that the templates can be accurately aligned during installation, avoiding shaping errors caused by template displacement and ensuring high precision in workpiece processing.

[0034] The working principle of this utility model is as follows: When using the mold, the workpiece is shaped by the mold-closing cooperation between the upper cavity of the upper template 4 and the surface of the lower template 5. When it is necessary to shape similar products or products of similar size, the locking screw 932 on the clamping plate 933 can be loosened and the adjusting seat 93 can be moved so that the pressure block 91 moves away from the upper template 4 or the lower template 5. At this time, the upper template 4 and the lower template 5 corresponding to the product can be replaced.

[0035] When fixing the upper template 4 or lower template 5, move the adjusting seat 93 so that the pressure block 91 is locked in the positioning groove 10 of the upper template 4 or lower template 5. Then tighten the locking screw 932 to fix the adjusting seat 93. Then tighten the clamping screw 92 again so that the pressure block 91 presses and fixes the upper template 4 or lower template 5, thereby completing the template replacement.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
