Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy wheel hub casting molds, in particular to a modular installation and positioning device for a wheel hub mold cooling pipeline. Background Art

[0002] Low-pressure casting is one of the most important production processes for aluminum alloy wheels. With the increase in market demand, product production efficiency has gradually improved. The wheel mold mainly consists of three parts: upper mold, side mold, and lower mold. In order to improve casting production efficiency, cooling pipes are usually arranged in the upper mold, side mold, and lower mold respectively. Compressed air or pure water are used to quickly cool each part, accelerate the sequential solidification of the casting, and thus efficiently produce wheel blanks.

[0003] To meet the demands of efficient production, improving cooling efficiency is one of the most direct ways to boost casting production efficiency. As technology matures, the demand for cooling pipes in molds increases. Currently, wheel hub molds have more cooling pipes than before. An 18-inch wheel has 8 to 11 cooling pipes in the upper mold, depending on the style. Currently, the upper mold cooling pipes are typically installed using a one-piece pressure plate. Multiple semicircular holes are drilled in the pressure plate, and multiple cooling pipes are pressed directly into the semicircular holes and secured with bolts at both ends.

[0004] After repeated assembly and disassembly of the mold, the cooling pipes become deformed. Installing the upper mold cooling pipe using a traditional integrated pressure plate is challenging. Slightly deformed cooling pipes, placed under the pressure plate, need to be individually adjusted and snapped into the semicircular holes of the pressure plate because they lack contact. This can easily cause already inserted cooling pipes to fall out, making installation difficult for a single person. For some slightly deformed cooling pipes that are difficult to snap into place, hammering is used. Forced bolt insertion often causes the threads in the upper mold mounting plate's bolt holes to slip, and over time, further deformation of the cooling pipe ends can occur, making installation impossible with external force. To ensure production schedules are met, the cooling pipes are often heated at high temperatures and then manually bent after softening. This poses a high risk of cracking the pipes and shortening their lifespan. Alternatively, the circular holes in the pressure plate are cut and damaged before the cooling pipes are forcibly inserted. This only provides lateral restraint, leaving the pipes in direct contact. Currently, during the mold repair process, installing the upper mold cooling pipe ends in two-thirds of molds takes over 10 minutes. This is not only difficult and labor-intensive, but also time-consuming and reduces the lifespan of the cooling pipes.

[0005] With the demand for casting production quality, thermocouple sensors are added to various parts of the mold to monitor the real-time temperature of each part and adjust parameters in real time to improve casting production quality. Thermocouple wires have no fixed placement area and often fall out and get damaged, affecting measurement.

[0006] Based on this, a modular installation and positioning device for the wheel hub mold cooling pipe was developed to reduce the difficulty of positioning and installing the end of the upper mold cooling pipe, achieve precise positioning and installation of the cooling pipe end, and realize the placement of the thermocouple wire at the same time. Summary of the Invention

[0007] The utility model aims to solve one of the technical problems existing in the prior art.

[0008] The present application provides a modular installation and positioning device for a wheel hub mold cooling pipe, comprising:

[0009] Cooling pipes and fixing bolts;

[0010] Also includes:

[0011] Several cooling pipe fixing blocks, each having a semicircular groove at its lower end, and the cooling pipes are installed on the cooling pipe fixing blocks through the semicircular groove;

[0012] A positioning track, on which the cooling pipe fixing block is movably mounted.

[0013] Positioning tracks include:

[0014] A limiting slot, which is provided at the lower end of the positioning track;

[0015] The cooling pipe fixing block is slidably installed in the limiting slot through a movable limiting block at the upper end of the semicircular slot.

[0016] Positioning tracks also include:

[0017] A movable slot, which is arranged at the upper end of the limit slot;

[0018] Wherein, the cooling pipe fixing block can slide longitudinally on the limiting slot through the movable slot.

[0019] Positioning tracks also include:

[0020] A trapezoidal positioning groove is provided at the top of the movable groove, and the trapezoidal positioning block provided at the top of the cooling pipe fixing block can be plugged into the trapezoidal positioning groove;

[0021] Wherein, two groups of left and right trapezoidal positioning grooves are arranged at equal intervals on both sides of the top of the movable groove.

[0022] Positioning tracks also include:

[0023] The end limit block can be inserted into the limit slot and can be detachably mounted on one end of the positioning track via the fixing bolt.

[0024] When the trapezoidal positioning block is placed in the trapezoidal positioning groove on the left, the facing sides of the cooling pipe fixing blocks corresponding to any two adjacent trapezoidal positioning grooves are in contact with each other, and the side of the cooling pipe fixing block located on the far left that is facing away from the other cooling pipe fixing blocks is in contact with the end of the limiting slot that is not equipped with the end limiting block.

[0025] When the trapezoidal positioning block is placed in the trapezoidal positioning groove on the right, the facing sides of the cooling pipe fixing blocks corresponding to any two adjacent trapezoidal positioning grooves are in contact with each other, and the side of the cooling pipe fixing block located on the far right facing away from the other cooling pipe fixing blocks is in contact with the end limit block.

[0026] Positioning tracks also include:

[0027] Side clamping grooves are arranged on both sides of the upper end of the positioning rail. A thermocouple fixing block is slidably installed on the side clamping grooves. A circular groove is arranged above the thermocouple fixing block. The thermocouple wire is clamped in the circular groove and then installed on the thermocouple fixing block.

[0028] The beneficial effects of the utility model are as follows:

[0029] 1. Through the setting of the positioning track, the cooling pipe fixing block can drive the cooling pipe to move horizontally and vertically in the positioning track before the cooling pipe is fixed and installed, so that the cooling pipe with a certain deformation can be placed in the semicircular groove at the lower end of the cooling pipe fixing block. Then, the horizontal position is appropriately adjusted and the fixing bolts on both sides are tightened to achieve positioning installation under the action of the trapezoidal positioning groove. This reduces the difficulty of positioning and installation of the cooling pipe end, reduces the labor intensity and installation time, and achieves accurate positioning installation, thereby improving the assembly efficiency of the mold.

[0030] 2. The side slots and thermocouple fixing blocks can efficiently arrange and fix multiple thermocouple wires to ensure their safety and integrity during use;

[0031] 3. The modular structure design of the cooling pipe fixing block and the thermocouple fixing block makes it easy to replace components according to the requirements of the cooling pipe and thermocouple. The replacement is simple, the subsequent maintenance is good, and the adaptability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0042] Below, in conjunction with the accompanying drawings, a modular installation and positioning device for a wheel hub mold cooling pipeline provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0043] Example 1:

[0044] like Figures 1 to 5As shown, an embodiment of the present application provides a modular installation and positioning device for a wheel hub mold cooling pipeline, including a cooling pipeline 1 and a fixing bolt 2; it also includes: a plurality of cooling pipe fixing blocks 3, the lower ends of which are provided with semicircular grooves 31, and the cooling pipeline 1 is installed on the cooling pipe fixing blocks 3 through the semicircular grooves 31; a positioning rail 4, and the cooling pipe fixing blocks 3 are movably installed on the positioning rail 4.

[0045] Furthermore, the positioning track 4 includes a limiting slot 41 , which is provided at the lower end of the positioning track 4 ; the cooling pipe fixing block 3 is slidably installed in the limiting slot 41 through the movable limiting block 32 at the upper end of the semicircular groove 31 .

[0046] Furthermore, the positioning rail 4 further includes a movable groove 42 , which is provided at the upper end of the limiting slot 41 ; wherein the cooling pipe fixing block 3 can slide longitudinally on the limiting slot 41 through the movable groove 42 .

[0047] Furthermore, the positioning rail 4 also includes a trapezoidal positioning groove 43, which is arranged at the top of the movable groove 42, and the trapezoidal positioning block 33 arranged at the top of the cooling pipe fixing block 3 can be inserted into the trapezoidal positioning groove 43; wherein, two groups of left and right trapezoidal positioning grooves 43 are arranged at equal intervals on both sides of the top of the movable groove 42.

[0048] Furthermore, the positioning rail 4 further includes an end limit block 44 , which can be inserted into the limit slot 41 and detachably mounted on one end of the positioning rail 4 via the fixing bolt 2 .

[0049] Furthermore, when the trapezoidal positioning block 33 is placed in the trapezoidal positioning groove 43 on the left, the facing sides of the cooling pipe fixing blocks 3 corresponding to any two adjacent trapezoidal positioning grooves 43 are in contact with each other, and the side of the cooling pipe fixing block 3 located on the far left that is facing away from the other cooling pipe fixing blocks 3 is in contact with the end of the limiting slot 41 that is not equipped with the end limiting block 44.

[0050] Furthermore, when the trapezoidal positioning block 33 is placed in the trapezoidal positioning groove 43 on the right side, the facing sides of the cooling pipe fixing blocks 3 corresponding to any two adjacent trapezoidal positioning grooves 43 are in contact with each other, and the side of the cooling pipe fixing block 3 located on the far right that is away from the other cooling pipe fixing blocks 3 is in contact with the end limit block 44.

[0051] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the positioning rail 4 is detachably mounted on the mold by the fixing bolts 2 at both ends. When the cooling pipe 1 is installed, the cooling pipe 1 is completely placed under the positioning rail 4. At this time, the fixing bolts 2 on both sides only play a positioning role, and there is still a certain distance between the positioning rail 4 and the mold. Under the influence of gravity, the trapezoidal positioning block 33 at the top of the cooling pipe fixing block 3 is not in the trapezoidal positioning groove 43. The cooling pipe fixing block 3 can slide freely in the limiting groove 41, which facilitates the installation of the cooling pipe 1 with a certain deformation in the semicircular groove 31 at the lower end of the cooling pipe fixing block 3.

[0052] After the cooling pipe 1 is installed, the cooling pipe fixing blocks 3 do not need to be adjusted one by one. The cooling pipe fixing blocks 3 can be divided into two groups and slid to the left and right sides of the positioning rail 4 respectively until the two outermost cooling pipe fixing blocks 3 are respectively fitted with the end of the limiting slot 41 without the end limiting block 44 and the end limiting block 44. At this time, the facing surfaces of each group of cooling pipe fixing blocks 3 are all fitted, and the trapezoidal positioning block 33 connected to the top of the cooling pipe fixing block 3 is directly below the trapezoidal positioning groove 43, which is convenient for reducing the difficulty of manually installing multiple cooling pipes 1. By tightening the fixing bolts 2, the positioning rail 4 is fitted with the mold. At this time, the trapezoidal positioning block 33 connected to the top of the cooling pipe fixing block 3 is in the trapezoidal positioning groove 43, and the installation and positioning of the cooling pipe 1 is completed.

[0053] Before installing the positioning rail 4, the operator can remove the fixing bolt 2 at one end of the end stopper 44 and pull out the end stopper 44. Then, install the corresponding number of cooling pipe fixing blocks 3 according to the number of cooling pipes 1. After installation, reinsert the end stopper 44 and install the fixing bolt 2, so that the cooling pipe fixing blocks 3 can only slide within the limit slot 41.

[0054] The semicircular groove 31 at the lower end of the cooling pipe fixing block 3 can be set according to the diameter of the cooling pipe 1, so that cooling pipes 1 of various sizes within a diameter of 16 mm can be installed. Six trapezoidal positioning grooves 43 are evenly spaced on the left and right sides of the movable groove 42, so that a maximum of 12 cooling pipes 1 can be installed.

[0055] When the cooling pipe fixing block 3 is damaged, it only needs to be replaced with a cooling pipe fixing block 3 of corresponding size, which has good later maintainability.

[0056] Example 2:

[0057] like Figure 1 、 Figure 2 and Figure 6As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the positioning rail 4 also includes side slots 45, which are arranged on both sides of the upper end of the positioning rail 4, and a thermocouple fixing block 5 is slidably mounted on the side slots 45, and a circular groove 51 is provided above the thermocouple fixing block 5; the thermocouple wire is mounted on the thermocouple fixing block 5 by being clamped in the circular groove 51.

[0058] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the thermocouple fixing block 5 is slidably installed on the positioning rail 4 through the side slot 45. After the fixing bolts 2 on both sides of the positioning rail 4 are tightened, the thermocouple fixing block 5 can only slide freely between a pair of fixing bolts 2. The thermocouple wire is installed on the thermocouple fixing block 5 through the circular groove 51. The external temperature sensor can monitor the temperature of various parts of the mold in real time through the thermocouple wire. A maximum of five thermocouple fixing blocks 5 can be installed on the positioning rail 4, which can ensure that each thermocouple wire can move laterally within the limit, thereby avoiding the thermocouple wire from falling out and being damaged during the transportation and disassembly of the mold, and at the same time ensuring that multiple thermocouple wires will not contact each other.

[0059] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.
