Technical Field

[0001] This utility model belongs to the technical field of casting molding equipment, and relates to adjustable and assembleable molding tools. Background Technology

[0002] Rotational castings are common in industrial production, such as gears, end caps, hubs, gear rings, and cylindrical castings. In this type of casting production, large quantities of castings can be produced using a complete mold-making process to reduce mold costs.

[0003] However, in some non-standard fields, the production of single-piece and small-batch castings using integral molds will reduce corporate profits and reduce production enthusiasm due to the high mold costs. As a result, in the actual production process, many companies use scraper molding to produce rotating castings in order to save on mold costs.

[0004] Therefore, there is an urgent need to develop a new molding tool to enable the production of single-piece, small-batch rotary castings, reduce production costs, and ensure product quality. Utility Model Content

[0006] The technical solution adopted by this utility model is an adjustable and assembleable modeling tool, including a scraper base, on which a conversion connector is vertically sleeved. The upper end of the conversion connector is upward and sleeved with the vertical insertion hole of the rotating rod. A long U-shaped groove is opened in the front elevation of the horizontal cantilever of the rotating rod. A radial adjustment rod is installed in the long U-shaped groove. The inner section of the radial adjustment rod has a long through groove. The long through groove of the radial adjustment rod is fixedly connected to the adjustment hole of the rotating rod by a fastening bolt. The outer section of the radial adjustment rod has a light hole and a pattern is installed by a fastening bolt.

[0009] The main body of the scraper base is a steel block. A protruding cylinder is fixedly installed at the center of the steel block. The inner surface of the cylinder is set with internal threads, which is called the central thread hole. A radial positioning hole is opened on the wall where the internal thread of the cylinder is located. Multiple pairs of thread holes are symmetrically arranged around the cylinder.

[0010] The adapter has the following structure: the middle section is a large-diameter cylindrical step; the lower section is a small-diameter threaded rod section three, which has the same specifications and dimensions as the second threaded rod section; and the upper section is a cylindrical head with an intermediate diameter, the outer diameter of which is the same as the outer diameter of the connecting rod body.

[0011] The rotating rod has the following structure: the main body of the rotating rod is in the shape of a horizontal cantilever, and the inner end of the rotating rod has a vertical through hole, which smoothly connects to the cylindrical head of the conversion connector; the front surface of the horizontal cantilever of the rotating rod has a long U-shaped groove, which extends through the outer end face of the rotating rod, and multiple horizontally transparent adjustment holes are spaced apart in the long U-shaped groove.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figure 1 The structure of this utility model's modeling tool includes a scraper base 1, on which a connecting rod 2 is vertically sleeved. The connecting rod 2 has multiple sections that are sequentially sleeved upwards. The upper end of the uppermost connecting rod 2 is inserted with a conversion connector 3 (or the connecting rod 2 can be omitted if needed, and the conversion connector 3 can be directly sleeved with the scraper base 1). The upper end of the conversion connector 3 is sleeved with the vertical insertion hole of the rotating rod 4. The horizontal cantilever front surface of the rotating rod 4 has a long U-shaped groove 43. A radial adjustment rod 5 is fitted in the long U-shaped groove 43 (with the axis of the connecting rod 2 or the conversion connector 3 as the rotation center, the radial adjustment rod 5 can adjust the rotation radius of the pattern 6). The inner section of the radial adjustment rod 5 has a long through groove 51. The long through groove 51 of the radial adjustment rod 5 is fixedly connected to the adjustment hole 42 of the rotating rod 4 by a fastening bolt 8. The outer section of the radial adjustment rod 5 has a light hole 52 and a pattern 6 is installed thereon by a fastening bolt 9.

[0019] like Figure 2The scraper base 1 serves as the load-bearing component of the entire device. Its main body is a thick steel block, which is heavy and has a low center of gravity, ensuring the balance of the entire device. Downward-bending counterweights 11 are provided on both sides of the steel block. Appropriate counterweights 11 are selected based on the mass of the pattern 6 to maintain the normal rotation of the pattern 6 and ensure the balance and stability of the entire device. A raised cylinder 13 is fixedly installed at the center of the steel block, with an internal thread on its inner surface, referred to as the central threaded hole. A radially fixed hole is opened on the wall where the internal thread of the cylinder 13 is located. Position hole 1 is used for the installation of positioning pin; multiple pairs of threaded holes 12 are symmetrically provided around the cylinder 13, and the central threaded hole and these surrounding threaded holes can be used for the connection of connecting rod 2 or adapter 3; the upper surface of the steel block is also engraved with angle markings of 0°~180° around the cylinder 13; except for the central threaded hole, the other threaded holes can be used to symmetrically install connecting rod 2 or adapter 3 on both sides, for the simultaneous molding of half-tooth ring type castings in pairs (when symmetrically made on both sides, two mold products can be made at the same time), which significantly saves the construction period.

[0020] See Figure 3 The connecting rod 2 has the following structure: the main body is a cylinder, and the lower end of the cylinder is a threaded rod segment 22 with a small diameter. This threaded rod segment 22 is fitted into the corresponding threaded hole in the scraper base 1. The upper end of the cylinder has an internal threaded hole 2, and the threaded rod segment 22 of the connecting rod 2 matches the internal threaded hole 2. The outer wall of the internal threaded hole 2 has two positioning holes 21 radially opened, which are also used for the installation of positioning pins. Multiple connecting rods 2 can be combined end to end in sequence (e.g., ...). Figure 1 ) or no connecting rod 2 (e.g.) Figure 8 This allows for the creation of scraper molding tools for rotating castings of varying heights. The threaded section 22 of the connecting rod 2 is matched with each threaded hole in the scraper base 1, and fitted accordingly to the required positions.

[0021] See Figure 4 The structure of the adapter 3 is as follows: the middle section of the adapter 3 is a large-diameter cylindrical step 31; the lower section of the adapter 3 is a small-diameter threaded rod segment 33, which has the same specifications and dimensions as the threaded rod segment 22; the upper section of the adapter 3 is a cylindrical head 32 with an intermediate diameter, the outer diameter of which is the same as the outer diameter of the main body of the connecting rod 2; it connects downwards through the threaded rod segment 33 to the internal threaded hole 2 at the upper end of the connecting rod 2. Figure 1 ) or scraper base 1 ( Figure 7 ) Threaded hole fitting, cylindrical head 32 upward fitting with through hole 41 of rotating rod 4 ( Figure 1 , Figure 8 The rotating rod 4 rotates around the cylindrical head 32 by external force, and the cylindrical step 31 serves as a support and axial positioning. The diameter of the cylindrical step 31 is larger than the diameter of the cylindrical head 32, and the diameter of the cylindrical head 32 is larger than the outer diameter of the threaded rod segment 33.

[0022] See Figure 5 The structure of the rotating rod 4 is as follows: the main body of the rotating rod 4 is in the shape of a horizontal cantilever, and the inner end of the rotating rod 4 has a vertical through hole 41. It smoothly connects with the cylindrical head 32 of the conversion connector 3 through the through hole 41, and can rotate around the center of the cylindrical head 32 under the action of external force; the front surface of the horizontal cantilever of the rotating rod 4 has a long U-shaped groove 43, which runs through the outer end face of the rotating rod 4. Multiple horizontally penetrating adjustment holes 42 are spaced apart in the long U-shaped groove 43. Figure 5 The embodiment shows five adjustment holes 42).

[0023] See Figure 6 The structure of the radial adjusting rod 5 is as follows: the inner section of the radial adjusting rod 5 is shaped to match the long U-shaped groove 43, and the total length of the radial adjusting rod 5 is significantly greater than the length of the long U-shaped groove 43. The inner section of the radial adjusting rod 5 installed in the long U-shaped groove 43 has a horizontal elongated slot 51, and the outer section of the radial adjusting rod 5 extending out of the long U-shaped groove 43 has two horizontal light holes 52. When the radial adjusting rod 5 is in the extended position, the elongated slot 51 is tightened to the adjusting hole 42 in the long U-shaped groove 43 by at least two fastening bolts 8, so that the radial adjusting rod 5 is fixed in the long U-shaped groove 43 in the rotating rod 4.

[0024] With the installation in an upright position as a reference, the overall height of the radial adjustment rod 5 (referred to as the width when laid flat) is slightly smaller than the long U-shaped groove 43 in the rotating rod 4. The two are connected and fixed by a clearance fit and two fastening bolts 8. The radial adjustment rod 5 can move horizontally within the long U-shaped groove 43 to meet the needs of castings of different radii of rotation. The maximum limit stroke of the radial adjustment rod 5 is such that when the radial adjustment rod 5 reaches the rightmost end of the long U-shaped groove 43, at least two adjustment holes 42 are reserved for fixing the fastening bolts 8 to ensure the reliability of the fastening connection.

[0025] See Figure 7 The structure of pattern 6 includes a connecting arm and a template body 62. The connecting arm has two light holes 61, which are the same size as the two light holes 52. The outline shape of the template body 62 is set according to the requirements of the workpiece drawing to be made. The two light holes 61 of pattern 6 are aligned with the two light holes 52 of radial adjustment rod 5 and are firmly fixed by two fastening bolts 9.

[0026] Compared to other complete prototypes, Pattern 6 requires only a small part to be made; that is, only the outer contour model of the circular part is created. The outline of the part is achieved through scraping molding, and the internal cavity is constructed using the same core assembly method as other molding methods. Pattern 6 is not limited to wood; for parts produced in a certain batch, iron or aluminum alloy models can also be used to make Pattern 6 more durable.

[0027] After ensuring strength, the pattern 6 is fixedly connected to the radial adjustment rod 5. Then, through the lateral adjustment of the radial adjustment rod 5 and the longitudinal height adjustment of the connecting rod 2 or the conversion joint 3, the scraper shape of a certain type of rotating body casting is realized.

[0028] The positioning pins or positioning screws are installed on the positioning hole 1 of the longitudinal cylinder 13 and the positioning hole 21 of the connecting rod 2. Their function is to ensure that the axial height of the connecting rod 2 and the conversion joint 3 is securely limited, so as to prevent accidental movement of the rotating rod 4 when it rotates in a circular motion.

[0029] The working principle of this modeling tool is as follows: (1) The connecting rod 2 is connected downward to the cylinder 13 of the scraper base 1 by a thread. The connecting rod 2 is positioned by two positioning screws to ensure that the required longitudinal dimensions meet the requirements. (2) The connecting rod 2 is connected to the adapter 3 by a thread. The two positioning screws on the upper part of the connecting rod 2 are used to position and lock the adapter 3 to ensure a secure connection. (3) The rotating rod 4 and the cylindrical head 32 of the upper section of the conversion joint 3 are smoothly connected by clearance fit to ensure that the rotating rod 4 rotates around the axis of the conversion joint 3; the cantilever of the rotating rod 4 is provided with a long U-shaped groove 43 and an adjustment hole 42; (4) The radial adjustment rod 5 is slidably placed in the long U-shaped groove 43 of the rotating rod 4 with clearance fit. After the extension position of the radial adjustment rod 5 is determined, it is connected and fixed as a whole by two fastening bolts 8. There are multiple adjustment holes 42 in the long U-shaped groove 43. When the radial adjustment rod 5 reaches the rightmost end of the long U-shaped groove 43, at least two fastening bolts 8 installation positions are reserved to ensure the connection of the fastening bolts 8. (5) In addition to the central threaded hole of the cylinder 13, the scraper base 1 has multiple threaded holes symmetrically arranged on the left and right. A pair of connecting rods 2 are connected through the symmetrical threaded holes to install two sets of devices for the simultaneous molding of two half-tooth ring castings. Angle lines are engraved around the cylinder 13 of the scraper base 1 to assist in the scraper molding of the half-tooth ring castings.

[0030] The working process of this utility model is as follows: 1) Create the shape of the scraper according to the rotating parts to be processed, and obtain pattern 6; 2) Install the rotating parts to be processed, and determine the working height of the pattern 6 and the distance between it and the scraper base 1 according to the rotating parts to be processed. 3) Adjust the height of the pattern 6 by tightening the threads of the connecting rod 2 and the adapter 3, and adjust the distance between the pattern 6 and the scraper base 1 by adjusting the radial adjusting rod 5; after adjustment, tighten all fastening bolts and positioning screws. 4) Start the molding process. By manually rotating the pattern 6, the radial adjustment rod 5 and the rotating rod 4 are driven to rotate around the axis of the cylinder 13. That is, the scraper drives the surrounding sand mold. The operator rotates the pattern 6 while tightening the sand mold to form the outer contour of the rotating part. The outer contour sand mold of the part is then cured (self-hardening or air blowing method) to obtain the required shape.

[0031] 5) Connect a pair of connecting rods 2 simultaneously through symmetrical threaded holes, and install two sets of devices (pattern 6 drives radial adjustment rod 5 and rotating rod 4) for the simultaneous molding of two half-tooth ring type castings.
