Technical Field
[0001] This utility model relates to the field of mold manufacturing and processing technology, and in particular to a drilling device based on mold manufacturing. Background Technology
[0002] Drilling devices for mold manufacturing refer to equipment, tooling, or mechanisms specifically designed, manufactured, or used in the mold manufacturing process to precisely machine the required holes (such as guide pin holes, ejector pin holes, screw holes, cooling water holes, cavity feature holes, etc.) on mold parts (such as templates, inserts, sliders, etc.).
[0003] In the field of mechanical manufacturing, drilling is a common processing procedure. Traditional drilling equipment mostly uses hydraulic or electric drive, which requires high technical skills from operators. Especially in the mold manufacturing field, due to the high hardness of mold materials and strict precision requirements, existing drilling equipment suffers from insufficient positioning accuracy and poor stability, which can easily lead to a decrease in product qualification rate. Therefore, we propose a drilling device based on mold manufacturing. Utility Model Content
[0004] In view of the problems of insufficient positioning accuracy and poor stability of the existing drilling equipment, which easily leads to a decrease in product qualification rate, this utility model is proposed.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A die-making device for manufacturing holes includes a base, the base being a U-shaped structure having a horizontal part and a vertical part, the horizontal part and the vertical part being integrally formed; The clamping unit includes four clamping mechanisms mounted on the vertical part. Each clamping mechanism includes a clamping plate. A rubber block is mounted on the inner side of the clamping plate. The inner side of the rubber block is provided with anti-slip textures arranged in a linear array. The clamping plate is driven by a driving component. A drilling template is located above the base and is adjusted for lifting by a multi-stage hydraulic push rod. The drilling template has drilling holes arranged in a rectangular array, through which a drilling device can perform directional punching.
[0006] As a technical solution of the mold manufacturing punching device of this utility model, the four corner edges of the horizontal part are provided with fixing holes for fixing the base, and the fixing holes are oblong fixing holes.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0019] Reference Figures 1-4 A die-making drilling device is provided. This die-making drilling device includes a base 1, which is a U-shaped structure with a horizontal part 101 and a vertical part 102. The horizontal part 101 and the vertical part 102 are integrally formed. The U-shaped base 1 is fixed to the worktable by bolts through the elongated holes at the four corners of the horizontal part 101. The horizontal position of the base 1 is adjusted by using the elongated holes to ensure that the vertical part 102 is aligned with the processing area. The integrally formed U-shaped base 1 improves the structural rigidity and stability and reduces the impact of vibration on the drilling accuracy. The clamping unit includes four clamping mechanisms mounted on the vertical part 102. Each clamping mechanism includes a clamping plate 201. A rubber block 202 is mounted on the inner side of the clamping plate 201. Anti-slip textures 2021 arranged in a linear array are formed on the inner side of the rubber block 202. The anti-slip textures 2021 face the workpiece contact surface. The clamping plate 201 is driven by a driving component. The four clamping mechanisms cooperate with the rubber block 202 to enhance the workpiece fixing force through multi-directional synchronous clamping. The anti-slip textures 2021 prevent slippage, which is especially suitable for high hardness mold materials. The drilling template 4 is located above the base 1 and is driven to rise and fall by a multi-stage hydraulic push rod 3. The drilling template 4 has drilling holes 401 arranged in a rectangular array. The drilling equipment (not shown in the figure) can perform directional punching through the drilling holes 401. The drilling template 4 has pre-set standardized drilling holes 401 (rectangular array arrangement). The multi-stage hydraulic push rod 3 precisely controls the rise and fall, realizes batch directional punching, and reduces manual positioning error.
[0020] Reference Figure 1 and 2 The four corner edges of the horizontal part 101 are provided with fixing holes 103 for fixing the base 1. The fixing holes 103 are oblong fixing holes. In application, the oblong fixing holes allow the position of the base 1 to be finely adjusted to adapt to different workbench installation environments and improve equipment compatibility.
[0021] Reference Figure 1 , Figure 3 as well as Figure 4 The driving component includes a fixed base 203 mounted on the vertical part 102, a dual-axis stepper motor 204 mounted on the fixed base 203, an active connecting arm 205 driven on the output shaft of the dual-axis stepper motor 204, and a driven connecting arm 206 mounted on the dual-axis stepper motor 204. Both the active connecting arm 205 and the driven connecting arm 206 are rotatably mounted on a clamping plate 201. The clamping plate 201 has an integrally formed active protrusion 2011 and a driven protrusion 2022. 12. The active protrusion 2011 and the driven protrusion 2012 are located on both sides of the clamping plate 201. The active protrusion 2011 is rotatably connected to the active connecting arm 205, and the driven protrusion 2012 is rotatably connected to the driven connecting arm 206. In application, the dual-axis drive ensures that the clamping plate 201 moves synchronously and avoids uneven force distribution at a single point. At the same time, the design of the active protrusion 2011 and the driven protrusion 2012 can simplify the transmission structure and improve the clamping response speed and stability.
[0022] Reference Figure 1 The bottom end of the multi-stage hydraulic push rod 3 is mounted on the horizontal part 101. The piston end of the multi-stage hydraulic push rod 3 is detachably mounted on the bottom of the drilling template 4 by bolts. In application, the multi-stage hydraulic push rod 3 and the drilling template 4 are detachably connected, which makes it easy to replace drilling templates 4 of different specifications and quickly adapt to the processing needs of multi-size molds.
[0023] Reference Figures 1-4The punching equipment includes a drive unit and an execution unit linked to the mold cavity. The execution unit is configured to perform directional punching on the mold workpiece through the drilling hole 401. The punching execution unit (such as a punch) is aligned with the drilling hole 401 of the drilling template 4. The position of the mold cavity can be linked by a sensor to achieve automatic punching path matching. In application, the punching path is guided by the drilling hole 401 on the drilling template 4 to ensure that the hole position is accurately matched with the mold structure and improve the product assembly qualification rate.
[0024] The working principle of this utility model is as follows: Preparation: Fix the base 1 to the workbench and check the oil pressure of the multi-stage hydraulic push rod 3 and the wiring connection of the dual-axis stepper motor 204; Workpiece clamping: Place the mold workpiece on the horizontal part 101 of the base, start the dual-axis stepper motor 204, drive the four sets of clamping plates 201 to move synchronously towards the center, and press the workpiece with rubber blocks 202. The anti-slip texture 2021 enhances the friction. Drilling template 4 installation and positioning: Install the corresponding drilling template 4 according to the position where the workpiece needs to be drilled, start the multi-stage hydraulic push rod 3 to adjust the height of the drilling template 4, so that the bottom surface of the drilling template 4 maintains a gap of 1-2mm with the surface of the workpiece (to avoid contact damage). Drilling: Start the drilling equipment, press down the punch along the drilling hole 401 on the drilling template 4 to complete the single hole punching. Then, use the multi-stage hydraulic push rod 3 to finely adjust the height of the drilling template 4 to process other holes in sequence, or replace the drilling template 4 to adapt to the new hole array. End of operation: Reset the multi-stage hydraulic push rod 3 to the initial position, release the clamping mechanism to remove the workpiece, clean up the debris and check the hole accuracy.
[0025] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
