Abstract
Description
Technical Field
[0001] This application belongs to the field of glass mold processing technology, and more specifically, relates to a fixture for processing the cooling holes of the initial mold of a glass mold. Background Technology
[0002] The primary mold is the core component of glass bottle forming equipment, primarily used to shape the bottle neck structure and ensure forming accuracy. The primary mold typically consists of a pair of half-mold bodies, with the mating surfaces precisely fitted by positioning ribs and grooves to ensure no misalignment during mold closing. Water-cooling holes are a key structural design element in glass molds used to improve cooling efficiency. Multiple water-cooling holes are evenly distributed along the circumference of the primary mold, penetrating the entire mold and parallel to its axial direction. Adjacent water-cooling holes are connected end-to-end by U-shaped water pipes, thus achieving interconnection. Currently, the method used to process water-cooling holes in the primary mold is as follows: first, the two half-mold bodies are closed and fixed to the milling machine's worktable using a special fixture. The primary mold is placed horizontally on the fixture, which applies a vertical force. The water-cooling holes are then machined into the primary mold using a drill bit on the milling machine. To ensure a more balanced force between the two half-mold bodies, the mating surfaces of the half-mold bodies need to be horizontal. Currently, this can only be determined by visual inspection, leading to some errors in the results. Utility Model Content
[0003] The purpose of this application is to provide a fixture for processing the cooling holes in the initial mold of a glass mold, which aims to solve the problem that existing fixtures for the initial mold of glass molds cannot ensure that the mold parting surface of the half mold body remains horizontal.
[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a fixture for processing the cooling holes of the initial mold of a glass mold, including: a support frame, which is fixedly installed on the worktable; A support block is fixedly installed on the workbench, and the initial mold is placed on the support block; A clamping assembly is fixedly installed on the top of the support frame and is used to apply a downward clamping force to the initial mold; A support rod, fixedly mounted on the workbench, is located outside the support block; and A horizontal detection plate is mounted on the support rod in a horizontal direction, and the horizontal detection plate has the freedom to rotate in the horizontal direction; When the horizontal detection plate rotates to the side close to the support block, one end of the horizontal detection plate is placed on the mold-closing surface of the half mold body. The installation of the half mold body is determined by judging whether the horizontal detection plate and the mold-closing surface of the half mold body are completely in contact.
[0005] In one possible implementation, the support rod is a cylindrical rod, which is fixedly mounted on the worktable in a vertical direction. One end of the horizontal detection plate is fitted onto the support rod, and the horizontal detection plate has the degree of freedom to move along the axial direction of the support rod.
[0006] In one possible implementation, the horizontal detection plate includes a detection plate body and a detection block, the detection plate body being movably connected to the support rod, and the detection block being fixedly installed at the bottom of the detection plate body at the end away from the support rod.
[0007] In one possible implementation, a fixed base is also included, which is fixedly mounted on the workbench. The top surface of the fixed base has a mounting through hole for mounting the support rod, and the side wall of the fixed base has a notch that runs through the fixed base from top to bottom and communicates with the mounting through hole. The two ends of the notch are connected by bolts.
[0008] In one possible implementation, the top of the support block is provided with a V-shaped positioning groove for placing the initial mold.
[0009] In one possible implementation, there are two support blocks, located on opposite sides of the support frame.
[0010] In one possible implementation, a magnet is fixedly mounted on the support surface of the support block.
[0011] In one possible implementation, the clamping assembly includes a power component and a pressure rod. The power component is fixedly installed on the top of the support frame, and the pressure rod is fixedly installed on the power output end of the power component. The power component is used to drive the pressure rod to reciprocate in the vertical direction, and the pressure rod abuts against the top of the initial mold under the action of the power component.
[0012] In one possible implementation, the power component is an electric actuator or a cylinder.
[0013] In one possible implementation, a flexible pad is mounted on the lower end of the pressure bar.
[0014] Compared with the prior art, the solution shown in this application's embodiment has a different approach. In this application, a fixture for processing the cooling holes in the initial glass mold mold consists of a support frame, a support block, and a support rod, all fixedly mounted on a worktable. The support frame provides support and installation space for the clamping assembly. The support block is located below the clamping assembly. After the initial mold is placed on the support block, the clamping assembly applies a downward clamping force to the initial mold, thereby clamping and fixing it. The support rod is located outside the support block. Because the horizontal detection plate can rotate horizontally on the support rod, it can move closer to or further away from the half-mold body on the support block. When assembling the preliminary mold onto the fixture of this application, one half of the mold needs to be placed on the support block with the mold-closing surface of the half facing upwards. Then, the horizontal inspection plate is rotated towards the side closer to the half of the mold and placed on the mold-closing surface of the half of the mold. Since the horizontal inspection plate is always horizontal, when there is an angle between the mold-closing surface of the half of the mold and the horizontal plane, there will be a gap between the mold-closing surface of the half of the mold and the horizontal inspection plate. When the mold-closing surface of the half of the mold is flush with the horizontal plane, the mold-closing surface of the half of the mold will be completely fitted with the horizontal inspection plate without any gap. The operator can insert a feeler gauge between the half of the mold and the horizontal inspection plate to determine whether there is a gap between them. When there is a gap between the mold-closing surface of the half of the mold and the horizontal inspection plate, the operator can manually adjust the position of the half of the mold until the mold-closing surface of the half of the mold is horizontal. At this time, the horizontal inspection plate is rotated away from the half of the mold, and then the other half of the mold is closed into place. Finally, the clamping assembly applies a downward force to the upper half of the mold to achieve clamping and fixing of the preliminary mold. Attached Figure Description

Detailed Implementation
[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0019] Please refer to the following: Figure 1 and Figure 2 The fixture for processing the cooling holes in the initial mold of a glass mold provided in this application will now be described. The fixture for processing the cooling holes in the initial mold of a glass mold includes: a support frame 101, a support block 102, a clamping assembly 103, a support rod 104, and a horizontal detection plate 105. The support frame 101 is fixedly installed on the worktable 2; the support block 102 is fixedly installed on the worktable 2, and the initial mold is placed on the support block 102; the clamping assembly 103 is fixedly installed on the top of the support frame 101 to apply a downward clamping force to the initial mold; the support rod 104 is fixedly installed on the worktable 2, and the support rod 104 is located outside the support block 102; the horizontal detection plate 105 is installed on the support rod 104 in the horizontal direction, and the horizontal detection plate 105 has the freedom to rotate in the horizontal direction; when the horizontal detection plate 105 rotates to the side close to the support block 102, one end of the horizontal detection plate 105 is placed on the mold mating surface of the half mold body 3, and the installation of the half mold body 3 is determined by judging whether the horizontal detection plate 105 and the mold mating surface of the half mold body 3 are completely fitted.
[0020] The fixture for processing the cooling holes of the glass mold preform provided in this embodiment, compared with the prior art, has the support frame 101, support block 102, and support rod 104 all fixedly installed on the worktable 2. The support frame 101 provides support and installation space for the clamping assembly 103. The support block 102 is located below the clamping assembly 103. After the preform is placed on the support block 102, the clamping assembly 103 clamps and fixes the preform by applying a downward clamping force. The support rod 104 is located outside the support block 102. Since the horizontal detection plate 105 can rotate horizontally on the support rod 104, the horizontal detection plate 105 can move closer to or further away from the half-mold 3 on the support block 102 by rotation. When assembling the initial mold onto the fixture of this application, one half mold body 3 needs to be placed on the support block 102 with the mold-closing surface of the half mold body 3 facing upwards. Then, the horizontal detection plate 105 is rotated to the side closer to the half mold body 3 and placed on the mold-closing surface of the half mold body 3. Since the horizontal detection plate 105 is always in a horizontal state, when there is an angle between the mold-closing surface of the half mold body 3 and the horizontal plane, there will be a gap between the mold-closing surface of the half mold body 3 and the horizontal detection plate 105. When the mold-closing surface of the half mold body 3 is flush with the horizontal plane, the mold-closing surface of the half mold body 3 will be completely fitted with the horizontal detection plate 105 without any gap. Operators can determine whether there is a gap between the half mold body 3 and the horizontal detection plate 105 by inserting a feeler gauge between them. When there is a gap between the mold closing surface of the half mold body 3 and the horizontal detection plate 105, the operator can manually adjust the position of the half mold body 3 until the mold closing surface of the half mold body 3 is horizontal. At this time, first rotate the horizontal detection plate 105 to the side away from the half mold body 3, and then close the other half mold body 3 into place. Finally, apply a downward force to the upper half mold body 3 through the clamping component 103 to achieve the clamping and fixing of the initial mold.
[0021] In this embodiment, the horizontal detection plate 105 is elongated, with one end of the horizontal detection plate 105 mounted to the support rod 104 along its length, and the other end of the horizontal detection plate 105 used to contact the mold-closing surface of the half-mold 3. When the horizontal detection plate 105 rotates away from the support block 102, the horizontal detection plate 105 will completely detach from the space directly above the half-mold 3, thereby allowing the other half-mold 3 to be properly assembled onto the half-mold 3 already placed on the support block 102.
[0022] In some embodiments, please refer to Figure 1 and Figure 2The support rod 104 is a cylindrical rod, which is fixedly installed vertically on the worktable 2. One end of the horizontal detection plate 105 is fitted onto the support rod 104, and the horizontal detection plate 105 has the freedom to move along the axial direction of the support rod 104. In this embodiment, the support rod 104 is a cylindrical rod, which is easy to machine on a lathe, thus greatly reducing production costs. One end of the horizontal detection plate 105 is provided with a mounting hole with the same outer diameter as the support rod 104, and the support rod 104 and the mounting hole are clearance fit. Therefore, the horizontal detection plate 105 can rotate around the support rod 104 along its axial direction, and can also move linearly along the axial direction (vertical direction) of the support shaft, thereby adjusting the height of the horizontal detection plate 105. When the parting surface of the half mold 3 has an angle with the horizontal plane, the top surface of the half mold 3 is in a state of uneven height. If the horizontal detection plate 105 cannot move vertically on the support rod 104, it can only rotate from the lower side of the half-mold 3 to the upper side. Therefore, to ensure the horizontal detection plate 105 can be smoothly placed on the mold-closing surface of the half-mold 3, a sliding fit is made between the horizontal detection plate 105 and the support shaft. The support shaft only restricts the horizontal detection plate 105's linear movement in the horizontal direction. Thus, the horizontal detection plate 105 can rotate around the axial direction of the support shaft and move up and down along the axial direction of the support shaft. First, the horizontal detection plate 105 is moved upward to a point higher than the highest point of the half-mold 3, then rotated to directly above the half-mold 3, and finally moved downward to contact the mold-closing surface of the half-mold 3. The support rod 104 is located on the side of the support block 102 away from the drill bit on the milling machine, so the support rod 104 and the horizontal detection plate 105 will not collide with the drill bit during operation.
[0023] In some embodiments, please refer to Figure 1 and Figure 5The horizontal detection plate 105 includes a detection plate body 106 and a detection block 107. The detection plate body 106 is movably connected to a support rod 104, and the detection block 107 is fixedly installed at the bottom of the detection plate body 106 away from the support rod 104. In this embodiment, the detection plate body 106 has a rectangular structure, and one end of the detection plate body 106 along its length is fitted onto the support rod 104. The top surface of the workbench 2 is parallel to the horizontal plane, while the support rod 104 fixed on the workbench 2 is perpendicular to the workbench 2, so the axial direction of the support rod 104 is vertical. Since the detection plate body 106 is perpendicular to the support rod 104, the bottom surface of the detection plate body 106 is parallel to the horizontal plane. The detection block 107 is detachably installed at the bottom of the detection plate body 106 away from the support rod 104. The bottom surface of the detection plate body 106 has a positioning groove for installing the detection block 107. The positioning groove positions the detection block 107, thereby ensuring the positional accuracy of the detection block 107 on the detection plate body 106. The detection block 107 is fixed to the detection plate body 106 with screws. The detection block 107 is made of wear-resistant material, thereby extending its service life. The detection plate body 106 contacts the mold parting surface of the semi-mold 3 through the detection block 107, so it is only necessary to ensure that the machining accuracy of the bottom surface of the detection block 107 meets the usage requirements, while the machining accuracy of the bottom surface of the detection plate body 106 does not have special requirements, thus greatly reducing the processing cost and processing difficulty.
[0024] In some embodiments, please refer to Figure 1 and Figure 5The system also includes a mounting base 108, which is fixedly mounted on the workbench 2. The top surface of the mounting base 108 has a mounting through hole 109 for mounting the support rod 104. A notch 110 is formed on the side wall of the mounting base 108, extending from top to bottom through the mounting base 108 and communicating with the mounting through hole 109. The two ends of the notch 110 are connected by bolts 111. In this embodiment, the mounting base 108 is disc-shaped. The mounting base 108 is fixedly mounted on the workbench 2 and provides support for the support rod 104. The mounting through hole 109 is located at the top center of the mounting base 108, extending from top to bottom through the entire mounting base 108. The inner diameter of the mounting through hole 109 matches the outer diameter of the support rod 104. The lower end of the support rod 104 is inserted into the mounting through hole 109. A notch 110 is formed on the outer wall of the fixed base 108, running from top to bottom through the entire fixed base 108 and communicating with the mounting through hole 109. The two ends of the notch 110 are connected by bolts 111, which are perpendicular to the axis of the mounting through hole 109. When the bolts 111 are tightened, the width of the notch 110 is reduced, thereby clamping and fixing the support rod 104 to the fixed base 108. When the bolts 111 are loosened, the limiting position on the support rod 104 is released, thereby adjusting the height of the support rod 104 or disassembling the support rod 104. The fixed base 108 is fixedly connected to the slider in the T-slot of the worktable 2 by screws.
[0025] In some embodiments, please refer to Figure 1 and Figure 2 The support block 102 has a V-shaped positioning groove 112 on its top for placing the initial mold. In this embodiment, the V-shaped positioning groove 112 is located on the top surface of the support block 102. The initial mold is placed in the V-shaped positioning groove 112. Since the initial mold is cylindrical, the outer wall of the single half mold body 3 is an arc surface. The two inclined surfaces of the V-shaped positioning groove 112 support the half mold body 3. Since there is a line contact between the V-shaped positioning groove 112 and the half mold body 3, the processing difficulty is reduced by decreasing the contact area between the two. At the same time, the V-shaped positioning groove 112 can also support initial molds of different diameters.
[0026] In some embodiments, please refer to Figure 1 and Figure 2There are two support blocks 102, located on both sides of the support frame 101. In this embodiment, the two support blocks 102 simultaneously support the semi-mold 3, providing two-point support for the semi-mold 3 and making the support for the semi-mold 3 more stable. Since the two support blocks 102 are located on both sides of the support frame 101, the support blocks 102 and the support frame 101 can be disassembled and assembled independently without affecting each other. The support blocks 102 are fixedly connected to the slider in the T-slot of the worktable 2 by screws. The support frame 101 is fixedly connected to the slider in the T-slot of the worktable 2 by screws. In some embodiments, please refer to Figure 1 A magnet 113 is fixedly installed on the support surface of the support block 102. In this embodiment, the V-shaped positioning groove 112 is the support surface of the support block 102 for the half-mold 3, so the magnet 113 is fixedly installed on the two inclined surfaces of the V-shaped positioning groove 112. The surface of the V-shaped positioning groove 112 has a groove for installing the magnet, and the depth of the groove is equal to the thickness of the magnet 113. When the half-mold 3 is placed on the support block 102, the magnet 113 attracts and fixes the half-mold 3, thereby preventing the half-mold 3 from shaking when in contact with the horizontal detection plate 105, and also avoiding the change in position of the adjusted half-mold 3 before mold closing due to accidental contact.
[0027] In some embodiments, please refer to Figure 1 and Figure 4 The clamping assembly 103 includes a power component 114 and a pressure rod 115. The power component 114 is fixedly installed on the top of the support frame 101, and the pressure rod 115 is fixedly installed on the power output end of the power component 114. The power component 114 drives the pressure rod 115 to reciprocate vertically, and the pressure rod 115 presses against the top of the initial mold under the action of the power component 114. In this embodiment, the support frame 101 has a U-shaped structure, and the initial mold is placed inside the U-shaped structure. The power component 114 is fixedly installed on the top of the support frame 101. The power output end of the power component 114 is its bottom, and the pressure rod 115 is fixedly installed on the power output end of the power component 114. The pressure rod 115 is located directly above the initial mold. The pressure rod 115 is a cylindrical rod. The power component 114 drives the pressure rod 115 to move downward in the vertical direction, so that the pressure rod 115 abuts against the top surface of the initial mold. The pressure rod 115 applies downward pressing force to the initial mold, thereby fixing the initial mold to the support block 102.
[0028] In some embodiments, please refer to Figure 1 and Figure 4 The power component 114 uses an electric push rod or a cylinder.
[0029] In some embodiments, please refer to Figure 4A flexible pad 116 is installed at the lower end of the pressure rod 115. In this embodiment, the flexible pad 116 is made of rubber or polyurethane. The flexible pad 116 has a certain degree of elasticity. The flexible pad 116 is fitted onto the bottom of the pressure rod 115, and the outer diameter of the flexible pad 116 is larger than the outer diameter of the pressure rod 115. The flexible pad 116 and the pressure rod 115 are connected by threads, which facilitates disassembly and assembly. The pressure rod 115 contacts the primary mold through the flexible pad 116, thus avoiding rigid collisions between the pressure rod 115 and the primary mold, preventing damage to the outer surface of the primary mold, and eliminating noise.
[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
