Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a die equal height structure. Background Technology

[0002] In manufacturing fields such as stamping, injection molding, and composite material molding, the mold closing accuracy directly affects the product molding quality. Traditional molds usually rely on guide pillars, guide sleeves, or positioning blocks to achieve alignment of the upper and lower molds. However, in large or complex curved surface molds, due to factors such as machining errors, thermal deformation, or uneven stress, problems such as uneven local gaps and misalignment are prone to occur during mold closing, resulting in defects such as product wall thickness deviation, flash, and insufficient filling.

[0003] In existing technologies, some solutions improve mold closing performance by increasing the number of guiding mechanisms or improving machining accuracy, but these are costly and difficult to completely eliminate microscopic deviations. Other solutions use elastic compensation elements (such as springs and air cushions), but these are prone to fatigue failure after long-term use and lack stability. In addition, for high-precision or thin-walled molding processes, traditional methods are difficult to achieve uniform mold closing pressure distribution, affecting product consistency. Utility Model Content

[0004] The purpose of this utility model is to provide a mold equal height structure to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] A mold equal-height structure includes: a lower mold base and a lower mold core plate. The lower mold base has a core plate groove, and the lower mold core plate is fixedly disposed in the core plate groove. The lower mold base is provided with a plurality of equal-height columns, which are arranged around the outer periphery of the core plate groove. The upper end of each equal-height column has a positioning end face.

[0007] The mold equal-height structure provided by this utility model has at least the following beneficial effects: the lower mold base, through multiple positioning end faces provided by multiple equal-height columns, can form equal-height support for the upper mold, so that the upper mold core plate can be pressed tightly onto the lower mold core plate after mold closing. The lower mold base controls the mold closing accuracy through the positioning end faces of the equal-height columns, reducing the overall machining accuracy requirements of the lower mold base while ensuring the mold closing effect. In the mold equal-height structure of this utility model, the lower mold core plate is positioned by the core plate groove, and the mold closing effect is precisely controlled by the height position of the positioning end faces of the equal-height columns, which reduces the difficulty of inspection and processing, thereby reducing the machining accuracy requirements of the lower mold base and the casting cost, which has significant economic benefits for production.

[0008] As a further improvement to the above technical solution, the positioning end face is provided with a measuring groove.

[0009] As a further improvement to the above technical solution, the equal-height column is in the shape of a cylindrical body extending vertically, and the equal-height column is coaxially provided with a screw countersunk hole, in which a connecting screw that is threadedly connected to the lower mold base is inserted.

[0010] As a further improvement to the above technical solution, the lower mold base is provided with a mounting boss, and the equal-height column is located on the upper side of the mounting boss.

[0011] As a further improvement to the above technical solution, the upper end of the mounting boss has a first mounting part, and the equal-height column is disposed on the upper side of the first mounting part.

[0012] As a further improvement to the above technical solution, the first mounting part includes a mounting plane perpendicular to the up and down direction and a first threaded hole coaxially arranged with the screw countersunk hole, and the connecting screw is threadedly connected to the first threaded hole.

[0013] As a further improvement to the above technical solution, a gasket is provided between the equal-height column and the first mounting part.

In the projection in the vertical direction, the measuring groove is located on one side of the positioning end face along the first direction, and the second mounting part is located on one side of the first mounting part along the first direction.

[0016] As a further improvement to the above technical solution, the projection of the core plate groove in the vertical direction is rectangular, and multiple mounting bosses and equal-height columns are arranged on the four sides of the core plate groove. Attached Figure Description

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Reference Figures 1 to 3 The mold height structure of this utility model is illustrated in the following embodiments:

[0027] A mold equal-height structure includes a lower mold base 100 and a lower mold core plate 200. The lower mold base 100 has an upwardly open core plate groove 110, and the lower mold core plate 200 is embedded in the core plate groove 110 and fixedly connected to the lower mold base 100. A plurality of equal-height columns 300 are provided on the upper side of the lower mold base 100, and the plurality of equal-height columns 300 are arranged around the outer periphery of the core plate groove 110. The upper end of each equal-height column 300 has a positioning end face 310.

[0028] In practical use, the lower mold base 100, through multiple positioning end faces 310 provided by multiple height-equal pillars 300, can form height-equal support for the upper mold, allowing the upper mold core plate to be pressed tightly onto the lower mold core plate 200 after mold closing. The lower mold base 100 controls the mold closing accuracy through the positioning end faces 310 of the height-equal pillars 300, reducing the overall machining accuracy requirements of the lower mold base 100 while ensuring the mold closing effect. In the mold height-equal structure of this utility model, the lower mold core plate 200 is positioned by the core plate groove 110, and the mold closing effect is precisely controlled by the height position of the positioning end faces 310 of the height-equal pillars 300. The detection and machining difficulties are low, thereby reducing the machining accuracy requirements and casting costs of the lower mold base 100, which has significant economic implications for production.

[0029] In some embodiments, the positioning end faces 310 of the plurality of equal-height columns 300 are flush with each other and set at the same height, forming a common supporting plane to support the upper mold. In this embodiment, to reduce the machining accuracy requirements of the upper mold, the heights of the positioning end faces 310 of the plurality of equal-height columns 300 are not set at the same height, but are adjusted according to the specific dimensions of the corresponding position of the upper mold.

[0030] To visually measure the mold-closing effect and facilitate debugging, the positioning end faces 310 of the equal-height columns 300 in this embodiment are all provided with measuring grooves 311. The bottom of the measuring groove 311 is flat and lower than the positioning end face 310. In this embodiment, the depth of the measuring groove 311 is 1mm. In actual use, the measuring wire is placed in the measuring groove 311. Before mold closing, the wire is higher than the positioning end face 310. After mold closing, the deformation of the wire under pressure can visually determine the pressing condition between the corresponding positioning end face 310 and the upper mold, thereby allowing for adaptive adjustments. The measuring groove 311 provides deformation space for the measuring wire, preventing indentations or damage to the upper mold or positioning end face 310 during measurement, which would affect the mold-closing effect.

[0031] In this embodiment, the leveling column 300 is cylindrical in shape and has a central axis extending vertically. A countersunk screw hole 312 is coaxially provided on the leveling column 300, and a connecting screw passes through the countersunk screw hole 312, which is threadedly connected to the lower mold base 100. Through this structure, the leveling column 300 is locked and fixed to the lower mold base 100 by the connecting screw in the countersunk screw hole 312, achieving a detachable connection between the leveling column 300 and the lower mold base 100. When needed, the leveling column 300 can be disassembled and replaced, or removed for precision machining and adjustment to achieve height correction.

[0032] In this embodiment, the lower mold base 100 is provided with a plurality of mounting bosses 120, the number of mounting bosses 120 being the same as the number of equal-height columns 300, and the equal-height columns 300 being arranged one-to-one on the upper side of the mounting bosses 120.

[0033] The upper end of the mounting boss 120 has a first mounting portion 121, and the equal-height column 300 is disposed on the upper side of the first mounting portion 121. The first mounting portion 121 includes a mounting plane perpendicular to the vertical direction and a first threaded hole coaxially disposed with the screw countersunk hole 312, and the connecting screw is threadedly connected to the first threaded hole.

[0034] The mounting plane is a precision-machined plane perpendicular to the vertical direction. The leveling post 300 is mounted on the upper side of the mounting boss 120, and the lower end of the leveling post 300 abuts against the upper end face of the mounting boss 120. The connecting screw passes through the countersunk hole 312 and is threaded into the threaded hole, thereby locking the leveling post 300 onto the upper side of the mounting boss 120.

[0035] The mounting boss 120 provides a high-precision mounting surface for the leveling column 300, reducing the machining accuracy requirements of the lower mold base 100. In actual production, after the lower mold base 100 is cast, the upper surface of the mounting boss 120 is precision machined, while other positions of the lower mold base 100 can remain as cast surfaces. This ensures the installation accuracy of the leveling column 300 and reduces processing costs.

[0036] During actual debugging, the height of the positioning end face 310 of the equal-height column 300 may be too high or too low. If the positioning end face 310 is too high, it can be adjusted during processing. If the positioning end face 310 is too low, a shim is placed between the equal-height column 300 and the first mounting part 121 to achieve height correction. The shim has a clearance hole, and the connecting screw passes through the clearance hole and connects to the threaded hole, thereby pressing the shim tightly against the mounting boss 120 by the equal-height column 300.

[0037] In a further embodiment, the mounting boss 120 further includes a second mounting portion 122, which is located beside the first mounting portion 121 and is flush with the mounting plane of the first mounting portion 121. One end of the gasket is located on the upper side of the second mounting portion 122. When there are many gaskets, the gasket is pre-fixed to the mounting boss 120 through the second mounting portion 122, thereby facilitating the installation and fixing of the equal-height column 300 and preventing the gasket from affecting the installation accuracy of the equal-height column 300, which could lead to mold damage. The second mounting portion 122 is flush with the mounting plane, and one end of the gasket is locked and fixed to the second mounting portion 122 by screws.

[0038] In some embodiments, the gasket is in the shape of a thin annular sheet, and the gasket is directly clamped and fixed by the leveling column 300. The second mounting part 122 can provide space for fixing the measuring wire. In the vertical projection, the measuring groove 311 is provided on one side of the positioning end face 310 along the first direction, and the second mounting part 122 is provided on one side of the first mounting part 121 along the first direction. The first direction extends radially along the leveling column 300. The measuring wire is fixed by a connecting block fixed to the second mounting part 122 so that the end of the measuring wire can be placed in the measuring groove 311. In some embodiments, the connecting block can be locked to the second mounting part 122 by screws, and the second mounting part 122 is provided with corresponding screw holes. In some embodiments, the connecting block can be fixed to the second mounting part 122 by magnetic attraction, adhesive, or other methods.

[0039] The core plate groove 110 has a rectangular projection in the vertical direction. The core plate groove 110 has four straight sides, which extend either in the front-back direction or the left-right direction. Multiple mounting bosses 120 and level posts 300 are arranged along the sides of the four straight sides in a straight line. (See attached figure.) Figures 1 to 3 The core plate groove 110 has three mounting bosses 120 and equal-height columns 300 arranged along the left-right direction on both its front and rear sides, and two mounting bosses 120 and equal-height columns 300 arranged along the front-back direction on both its left and right sides. The total number of mounting bosses 120 and equal-height columns 300 is ten. The mounting bosses 120 and equal-height columns 300 correspond one-to-one and are arranged along the edge of the core plate groove 110, providing high-precision support for the edge of the core plate groove 110 to ensure the effective mold closing of the upper and lower molds.
