Description

Technical Field

[0001] This utility model relates to the technical field of injection molding equipment, and in particular to a general-purpose shaping machine for injection molding parts. Background Technology

[0002] In injection molding, the production of injection molded parts is a complex and delicate process. After the injection molded parts cool and solidify in the mold, defects such as deformation, dents, and warping often occur on the surface or inside the parts due to factors such as minor errors in the mold, the shrinkage characteristics of the material, or uneven pressure distribution during the injection process. These defects not only affect the appearance quality of the injection molded parts but may also adversely affect their functionality and structural strength.

[0003] To improve the quality of injection molded parts, subsequent shaping processes are usually required. However, traditional shaping methods often use a single pressing tool or mold, which is difficult to adapt to the shaping needs of injection molded parts of different sizes and different locations on the parts. For injection molded parts with significant size differences, using the same set of shaping tools may result in poor shaping effects or even damage to the injection molded parts. Furthermore, the shaping requirements for different locations on the injection molded parts may also vary, and traditional shaping methods are unable to meet these diverse shaping needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot simultaneously press and shape injection molded parts of different specifications and at different locations, and to propose a universal shaping machine for injection molded parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A universal forming machine for injection molded parts includes: a cabinet, wherein a plurality of first oblong holes are provided parallel to each other on the table panel of the cabinet;

[0007] The first adjusting strip is adjustablely fixed inside the first waist-shaped hole and is arranged in a direction perpendicular to the first waist-shaped hole;

[0008] A pad block is installed on the first adjusting strip and has a stepped surface that is suspended to support and secure the product to be shaped.

[0009] A support frame is fixed on the table panel; a shaping power source is suspended and fixed on the support frame, and a shaping frame is fixed on its output shaft. The shaping frame includes a first shaping strip, a second shaping strip, and a shaping block.

[0010] The first shaping strip has a second waist-shaped hole on it;

[0011] The second shaping strip is set perpendicular to the first shaping strip and is adjustablely fixed in the second waist-shaped hole, and a third waist-shaped hole is also provided thereon; the shaping block is adjustablely fixed in the third waist-shaped hole.

[0012] Furthermore, a pressure block locking plate is installed at the middle position of the first shaping strip, and a middle shaping block is fixed on the pressure block locking plate with adjustable height.

[0013] Furthermore, it also includes: a third shaping strip, which is set perpendicular to the middle position of the first shaping strip and is located on the same plane as the lower surface of the first shaping strip, and has a fourth waist-shaped hole.

[0014] Furthermore, a groove matching the width of the first shaping strip is provided in the middle of the second shaping strip, and a screw hole is provided in the center of the groove.

[0015] Furthermore, both the shaping block and the intermediate shaping block have screw holes at the center of their top surfaces, and adjusting screws are screwed into the screw holes. At least two fastening screws are screwed onto the adjusting screws.

[0016] Furthermore, the four corners of the platform are fixed with support columns, the top of the support columns are connected to support rods, the support rods are fixed with power source plates, and the power source plate is installed in the middle position of the power source plate.

[0017] Furthermore, linear bearings are fixed at both ends of the power source plate, and bearing guide posts are inserted inside the linear bearings. The fixed ends of the bearing guide posts are fixed to the first shaping strip.

[0018] Furthermore, both the shaping block and the intermediate shaping block are ABS plastic blocks.

[0019] Furthermore, the sum of the output shaft length, the height of the adjusting screw, and the height of the intermediate shaping block is greater than or equal to the sum of the elevating column length, the support rod height, and the power source plate height.

[0020] Furthermore, the injection-molded part is the base shell of the LED display screen.

[0021] As can be seen from the above, the universal shaping machine for injection molded parts provided in this application completes the positioning of products of different specifications to be shaped by adjusting the position of the pad block in the first waist-shaped hole and the first adjusting strip. Then, driven by the shaping power source, the various components of the shaping frame work together, and the shaping block can adjust its position along the second waist-shaped hole and the third waist-shaped hole, so that the shaping block can press and shape at different positions of the product to be shaped, thereby realizing the ability to press and shape injection molded parts of different specifications at different positions.

[0041] Reference Figures 1-10 The universal shaping machine for injection molded parts according to this utility model includes the following embodiments.

[0042] Implementation Method 1: Basic Implementation Method of a Universal Shaping Machine for Injection Molded Parts

[0043] Please refer to Figures 1-5 This embodiment relates to a universal forming machine for injection molded parts, the specific structure of which is as follows:

[0044] The cabinet 1 has multiple first oblong holes that are parallel to each other along the width direction on the tabletop 2 of the cabinet 1.

[0045] The first adjusting strip 21 is adjustablely fixed inside the first oblong hole and is arranged in a direction perpendicular to the first oblong hole. The first adjusting strip 21 is arranged along the length of the cabinet 1 and its length is greater than the length of the cabinet 1. The part of the length exceeding the length is suspended on both sides of the cabinet 1. Two oblong holes are opened on the outer side of the first adjusting strip 21. The oblong holes are axially symmetrically distributed with respect to the central vertical line, which makes the pad 211 more stable when installed on the oblong holes, and at the same time can maximize the size of the product 3 to be shaped.

[0046] The first adjusting strip 21 can be flexibly adjusted in position within the first waist-shaped hole according to different shaping needs, adapting to various plastic parts of different widths.

[0047] The pad 211 has a stepped surface that is suspended and supports the product 3 to be shaped. The pad 211 is located on the first adjusting strip 21 at the position where the first waist-shaped hole and the waist-shaped hole of the first adjusting strip 21 intersect and overlap. The bottom surface of the pad 211 is square and the top surface is L-shaped. A square stepped surface is provided on the pad 211 to accommodate the four corners of the product 3 to be shaped. The pad 211 is symmetrically distributed at the four corners of the product 3 to be shaped, and a square stepped surface is provided in the direction corresponding to the product 3 to be shaped. Where the first waist-shaped hole in the middle part of the table panel 2 intersects with the first adjusting strip 21, a pad 211 is installed between the two waist-shaped holes on the first adjusting strip 21. The pad 211 has a stepped surface at half the height and width to accommodate the product 3 to be shaped, and its cross-section is L-shaped. The pad 211 is symmetrically distributed on two long sides in the direction corresponding to the product 3 to be shaped, so that the edge of the middle part of the product 3 to be shaped is engaged in the stepped surface of the pad 211, so that the product 3 to be shaped can be suspended on the table panel 2. The stepped surface is designed to stably place the injection molded part to be shaped, ensuring that the part does not shift during the shaping process. The product 3 to be shaped is engaged within the stepped surface of the pad 211, which is higher than the top of the pad 211. The top of the pad 211 also has multiple threaded holes for fixing it to the first adjusting strip 21 with screws, and for connecting the sliding mechanism at the bottom of the pad 211. This sliding mechanism moves between the first waist-shaped hole and the first adjusting strip 21, thereby moving the pad 211 to accommodate products 3 of different sizes and specifications. The pads 211 located between the waist-shaped holes on the first adjusting strip 21 are directly fixed to it with screws. Therefore, by adjusting the positions of the four corner pads 211, precise positioning and fixing of the product 3 to be shaped can be achieved, ensuring the stability and consistency of the shaping process.

[0048] A support frame 4 is fixed on the table panel 2 to support the shaping power source 5 and the shaping frame 6.

[0049] The shaping power source 5 is suspended and fixed on the support frame 4. A shaping frame 6 is fixed on the output shaft of the shaping power source 5. The shaping frame 6 includes a first shaping strip 61, a second shaping strip 62, and a shaping block 64. The shaping power source 5 is located at the top center of the support frame 4. Its bottom air rod passes through the support frame 4 and connects to the first shaping strip 61. The shaping power source 5 is a downward pressure cylinder or a linear motor. The inner diameter of the cylinder barrel of the downward pressure cylinder is 80 mm. The shaping frame 6 is connected to the corresponding position of the shaping power source 5, and its two ends are fixedly connected to the bearing guide posts. Through the downward pressure action of the shaping power source 5, the shaping frame 6 is driven to move smoothly downward along the bearing guide posts.

[0050] The first shaping strip 61 has four second waist-shaped holes. The waist-shaped holes at both ends of the first shaping strip 61 protrude vertically from the support rod 42. The first shaping strip 61 near the inner side of the support rod 42 has holes for the bearing guide post to pass through and be fixed. These holes are symmetrically distributed and separate the waist-shaped holes on the first shaping strip 61. A shaping block 64 is screwed into the center of the first shaping strip 61. The first waist-shaped holes are symmetrically arranged on the first shaping strip 61 with respect to the axial direction of the shaping block 64.

[0051] The second shaping strip 62 is perpendicular to the first shaping strip 61, and the second waist-shaped hole is adjustablely fixed on the first shaping strip 61. The second shaping strip 62 is also provided with a third waist-shaped hole. The second shaping strips 62 are parallel to each other and are screwed to both ends of the bottom of the first shaping strip 61. The second shaping strips 62 intersect the first shaping strip 61 perpendicularly, and the first shaping strip 61 separates their third waist-shaped holes.

[0052] The shaping block 64 is height-adjustably fixed in the third oblong hole. By adjusting the position of the shaping block 64 in the third oblong hole, different positions of injection molded parts of different sizes can be pressed and shaped to meet the shaping needs of different injection molded parts. The shaping block 64 is slidably connected to the third oblong hole on the second shaping strip 62 and screwed to the center position on the first shaping strip 61. The bottom of the shaping block 64 on the first shaping strip 61 is cylindrical and the top is an adjusting screw. The adjusting screw at the top of the shaping block 64 on the second shaping strip 62 is clamped in the third oblong hole. Its bottom is square and can be slidably adjusted in the third oblong hole, thereby achieving precise shaping at multiple angles and positions.

[0053] Implementation Method 2: A universal forming machine for injection molded parts with a pressure block locking plate 65 and an intermediate forming block 66

[0054] This implementation method is an improvement on implementation method one, as detailed below:

[0055] In addition to the structure described in Embodiment 1, a pressure block locking plate 65 is installed at the middle position of the first shaping strip 61. A middle shaping block 66 is fixedly mounted on the pressure block locking plate 65 with adjustable height. This middle shaping block 66 allows for pressing and shaping of the center position of the injection molded part. The pressure block locking plate 65 has a screw hole at its middle position for connecting the middle shaping block 66, and screw holes at both ends for connecting the first shaping strip 61. All of these screw holes are located along the length of the pressure block locking plate 65 in a straight line. The adjustable height of the pressure block locking plate 65 allows the middle shaping block 66 to be flexibly adjusted in height according to the shaping requirements of different injection molded parts.

[0056] Implementation Method 3: A universal forming machine for injection molded parts including a third forming strip 63

[0057] This embodiment adds the following components to the first embodiment:

[0058] In addition to the structure described in Embodiment 1, a third shaping strip 63 is also included. The third shaping strip 63 is positioned perpendicular to the middle of the first shaping strip 61, and is fixed by welding; two strips are used. The lower surfaces of the third shaping strip 63 and the first shaping strip 61 are on the same plane, and a fourth oblong hole is formed thereon. The third shaping strip 63 is located on both sides of the first shaping strip 61 and parallel to the second shaping strip 62. The third shaping strip 63 is used to press and shape the intermediate strip of the injection molded part. Adjustment is achieved through the shaping block 64 within the fourth oblong hole, enabling precise control of the intermediate strip of the injection molded part and enhancing the shaping effect.

[0059] Implementation Method 4: A universal forming machine for injection molded parts with a groove in the middle of the second forming strip 62.

[0060] Please refer to Figures 9-10 This embodiment is an improvement on the second shaping strip 62 based on embodiment one:

[0061] The second shaping strip 62 has a groove in its middle that matches the width of the first shaping strip 61, and a screw hole is formed at the center of the groove. At the intersections of the second shaping strip 62 and the first shaping strip 61 at both ends, grooves are formed to accommodate the width of the second shaping strip 62, allowing the first shaping strip 61 to be embedded within the grooves and ensuring the stability of the second shaping strip 62. A screw hole is formed at the center of each groove for fixing the second shaping strip 62 to the first shaping strip 61, and the overall structure is strengthened by screw connection.

[0062] Implementation Method 5: Universal forming machine for injection molded parts with adjusting screw and fastening screw

[0063] This embodiment improves upon Embodiment 1 by modifying the structure of the shaping block 64 and the intermediate shaping block 66:

[0064] Screw holes are provided at the center of the top surface of both the shaping block 64 and the intermediate shaping block 66. Adjusting screws are screwed into the screw holes, and at least two fastening screws are screwed onto the adjusting screws. The adjusting screw is cylindrical, with a fastening screw, specifically a flange nut, screwed to its bottom. At least two flange nuts are positioned above the shaping block 64 and between the second shaping strip 62; one contacts the top surface of the shaping block 64, and the other contacts the bottom surface of the second shaping strip 62. The position of the flange nut is adjusted to accommodate different heights of the third oblong hole. In special environments, appropriate flange nuts can be installed according to the height of the adjusting screw or the distance between the shaping block 64 and the second shaping strip 62, achieving multi-level precise adjustment. The flange nut is used to limit the movement of the shaping block 64 and the second shaping strip 62. The adjusting screw above the flange nut passes through the third oblong hole, allowing it to slide within the hole and adjust its position. A stop is provided at the top of the adjusting screw, i.e., on the top surface of the second shaping block 64. This stop is a cylinder fitted onto the adjusting screw, and its maximum width in the width direction of the third oblong hole is slightly larger than the width of the third oblong hole, ensuring that the adjusting screw does not come off during sliding. In other words, the distance between the adjustable fastening screw and the stop is equal to the height of the second shaping strip 62, thereby achieving the limit of the adjusting screw, thus adapting to the needs of injection molded parts of different specifications and improving the shaping accuracy.

[0065] Furthermore, the intermediate shaping block 66 is directly screwed onto the pressure block locking plate 65. Therefore, its adjusting screw does not have a stopper on top; instead, it is directly screwed into the screw hole of the pressure block locking plate 65. The top surface of the intermediate shaping block 66 and the bottom surface of the pressure block locking plate 65 are then limited and fixed by the fastening screws below. Through the cooperation of the adjusting screw and the fastening screw, the height of the shaping block 64 and the intermediate shaping block 66 is adjustable, thereby enabling precise adjustment of the height of the shaping components to adapt to different shaping requirements.

[0066] Implementation Method Six: A universal forming machine for injection molded parts with components such as support columns 41 at the four corners of the table panel 2.

[0067] This embodiment improves upon embodiment one by modifying the structure around the tabletop 2:

[0068] Elevating columns 41 are fixed at the four corners of the tabletop 2. Support rods 42 are connected to the top of the elevating columns 41, and power source plates 43 are fixed on the support rods 42. A shaping power source 5 is installed in the middle of the power source plate 43. The support frame 4 includes elevating columns 41, support rods 42, power source plates 43, and shaping power sources 5. One end of the elevating column 41 is screwed to the four corners of the tabletop 2, and the other end is connected to the support rods 42. The support rods 42 connect two elevating columns 41 in the width direction of the cabinet 1, making them parallel to each other. Power source plates 43 are fixed on the support rods 42, and shaping power sources 5 are installed in the middle of the power source plate 43. The elevating column 41 has a cylindrical structure, and the support rods 42 connected to its top are rectangular. The width of the power source plate 43 is larger than the bottom surface of the shaping power source 5. Multiple screw holes are opened at the connection between the power source plate 43 and the support rod 42, specifically three screw holes, for connection by screws. The sleeve of the shaping power source 5 is square, with its four corners connected by screws. A piston rod is located in the middle, passing through the power source plate 43 and the sleeve, and connecting to the pressure block locking plate 65 below. This allows the pressure block locking plate 65 to move up and down along the platform 2. Additionally, the support frame 4 and the power source plate 43 have several holes for fixing the wiring harness, ensuring neat wiring and safe equipment operation.

[0069] Implementation Method Seven: A Universal Shaping Machine for Injection Molded Parts with Linear Bearings and Bearing Guide Pillars

[0070] This embodiment further improves the connection structure between the power source plate 43 and the shaping frame 6 based on embodiment six:

[0071] Linear bearings are fixed at both ends of the power source plate 43, and bearing guide posts are inserted inside the linear bearings. The fixed ends of the bearing guide posts are fixed to the first shaping strip 61, thus constraining the power source plate 43 and the first shaping strip 61 to the same vertical plane. Through this structure, the power source plate 43 and the shaping frame 6 are connected by the linear bearings and the bearing guide posts inserted inside them to achieve relative motion along a predetermined trajectory by means of the shaping power source 5, ensuring the accuracy and stability of the shaping operation.

[0072] Implementation Method 8: A universal forming machine for injection molded parts using ABS plastic blocks as forming blocks 64 and intermediate forming blocks 66

[0073] This embodiment is based on Embodiment 1, and the materials of the shaping block 64 and the intermediate shaping block 66 are limited as follows:

[0074] Both the shaping block 64 and the intermediate shaping block 66 are ABS plastic blocks. ABS material has good heat resistance, enabling it to adapt to injection molding processes in high-temperature environments and ensuring the smooth progress of the shaping process. In addition, ABS plastic blocks also have good plasticity, making it easier to make fine adjustments and adapt to injection molded parts of various complex shapes, thereby improving shaping accuracy. By utilizing the characteristics of ABS plastic blocks, their service life is extended.

[0075] Implementation Method Nine: A Universal Shaping Machine for Injection Molded Parts that Meets Length Excess Pressing Requirements

[0076] This embodiment, based on embodiment one, specifies the dimensions of the shaping machine:

[0077] The sum of the length of the output shaft, the height of the adjusting screw, and the height of the intermediate shaping block 66 must be greater than or equal to the sum of the length of the support column 41, the height of the support rod 42, and the height of the power source plate 43. This design principle aims to achieve a length-surplus pressing function. Specifically, by accurately calculating and reasonably adjusting the dimensions of these three key components, sufficient travel margin can be ensured during the operation of the entire system, thereby effectively avoiding pressing difficulties or mechanical interference caused by insufficient length. This design not only improves the stability and durability of the equipment but also ensures smoothness and accuracy during operation.

[0078] Implementation Method 10: A universal forming machine for injection molded parts for shaping the bottom shell of LED displays

[0079] This embodiment, based on embodiments one through nine, limits the applicable injection molded parts:

[0080] In this embodiment, the injection molded part is the bottom shell of an LED display screen. The general-purpose forming machine for this injection molded part can perform forming operations on the bottom shell of the LED display screen. Based on the various structures and operations described above, it can meet the forming requirements of the bottom shell of the LED display screen and realize the correction and optimization of its shape.

[0081] Working principle or assembly process: First, the position of the pad 211 on the first oblong hole and the first adjusting strip 21 is adjusted to fit the size of the product 3 to be shaped. Then, the corresponding shaping blocks 64 are installed at the predetermined positions of the second shaping strip 62 and the third shaping strip 63. The shaping blocks 64 can slide in the third oblong hole and the fourth oblong hole. The position of the second shaping strip 62 can be adjusted on the second oblong hole, thereby realizing the adjustment of the X and Y axes of the shaping blocks 64. Then, the shaping power source 5 is started, causing the bearing guide column on the power source plate 43 to drive the shaping frame 6 to move, thereby driving the shaping blocks 64 and the intermediate shaping blocks 66 to apply pressure to different positions of the product 3 to achieve the shaping purpose. When the shaping blocks 64 contact the surface of the product 3 to be shaped, they are finely adjusted according to the shape and size of the LED display screen bottom shell until the ideal shaping effect is achieved. After the operation is completed, the shaping power source 5 is turned off and the shaped product 3 is removed.

[0082] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
