Description

Technical Field

[0001] This invention relates to the field of injection molding technology, and in particular to a mold-making device and its usage method. Background Technology

[0002] In the injection molding industry, one injection molding machine often corresponds to multiple molds for production. After the previous product is completed, the mold for the next product is switched onto the machine for production. During the mold change process, the operator uses a mold clamping device to fix the mold onto the injection molding machine before starting production.

[0003] Currently, the most common mold clamping method in the injection molding industry is the structure of a positioning ring + pressure plate. When changing molds, first align the positioning ring on the mold with the positioning hole on the fixed mold base plate of the equipment, and then push the mold through the moving mold base plate of the equipment to make the positioning ring of the mold enter the positioning hole and press the mold to ensure that the mold sprue sleeve is concentric with the equipment nozzle. Then, after the mold is pressed by the moving and fixed mold base plates of the equipment, the moving and fixed molds are clamped onto the moving and fixed mold base plates of the equipment respectively by the pressure plate and screws.

[0004] The above-mentioned mold clamping device is simple to operate, has low requirements for the mold base plate, and is flexible in clamping position. However, it has the following problems: First, the mold clamping time is long. Operators need to align the mold positioning ring with the positioning hole of the equipment first, and then use pressure plates to clamp the moving and fixed molds. To ensure that the mold does not slip, multiple pressure plates are needed to clamp the mold. Second, the labor intensity is high. Operators need to position the mold first, and then put on the pressure plates and tighten the screws. Due to the large number of pressure plates (multiple positions of upper, lower, left, and right pressure plates), the operation is cumbersome. Third, there are safety hazards. When fixing the mold, operators need to enter the equipment to put on the pressure plates, or even climb to the top of the mold. The mold is only fixed to the equipment by the pressure plates. During frequent movement, the mold is prone to slippage or even falling. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of this application is to provide a coding device and its usage method to solve the problems of time-consuming, labor-intensive, and safety hazards of the prior art injection molding coding device.

[0006] To achieve the above and other related objectives, in a first aspect, this application provides a mold clamping device, installed on an injection molding machine, for positioning and clamping a mold, the mold clamping device comprising:

[0007] The base plate is disposed opposite to the injection molding equipment;

[0008] The base plate has mounting positions opposite each other in the width direction, and guide rails for guiding are opposite each other on both sides of the mounting positions in the height direction. At least two sets of positioning holes are opened between the guide rails. The base plate also has positioning components for positioning the mold in the height direction opposite each other in the width direction.

[0009] A clamping mechanism is provided on the mounting position for positioning and clamping the mold in the width direction;

[0010] The clamping mechanism includes a base with guide grooves on both sides that mate with the guide rail. The base can move along the guide rail within the mounting position. A T-shaped block is provided on the base, and pressure plates are provided on both sides of the crossbar of the T-shaped block. Both the T-shaped block and the pressure plates extend out of the base toward the mold. A rotating seat and a positioning post are provided on both sides of the vertical bar of the T-shaped block. A first mounting position is provided on the rotating seat, and a second mounting position is provided on the positioning post. A rotating arm is provided on the first mounting position and the second mounting position. The rotating arm is mounted on the first mounting position via a rotating pin and can rotate about the rotating pin. The positioning post passes through the base and contacts the bottom of the positioning hole. The rotating arm is mounted on the second mounting position via the positioning pin.

[0011] Optionally, the positioning component includes a slide rail, a slider, and a positioning block. The slider is movably disposed on the slide rail and can move on the slide rail. The positioning block is disposed below the slide rail.

[0012] Optionally, the mounting position is provided with a limiting surface for limiting, and the mounting position is provided with a limiting block for limiting on the side near the guide rail. The clamping mechanism can move along the guide rail to make the base contact the limiting surface or the base contact the limiting block.

[0013] Optionally, the limiting block is provided with a limiting pin for positioning and a fixing member for installation. The limiting pin positions the limiting block on the base plate, and the fixing member connects the limiting block to the base plate.

[0014] Optionally, the clamping mechanism further includes a mounting block connected to the base plate. The bottom of the base has a mounting groove, and the clamping mechanism is mounted on the base plate by the cooperation of the mounting block and the mounting groove.

[0015] Optionally, a clamping member and a guide member are provided on the pressure plate, and an elastic member is provided on the clamping member. The base is provided with a first mounting hole for installing the elastic member and a second mounting hole for installing the guide member. The clamping member passes through the pressure plate and the elastic member in sequence to lock the pressure plate on the base.

[0016] Optionally, the base is further provided with a U-shaped block that surrounds the rotating arm, and a pull pin is provided between any of the U-shaped blocks and the rotating arm. A limiting groove matching the rotating arm is also provided on the surface of the base that contacts the rotating arm.

[0017] Optionally, a positioning pin is provided between the positioning pin and the rotating arm, and the positioning pin connects the positioning pin and the rotating arm. When the rotating arm rotates and rises, it drives the positioning pin to rise synchronously away from the positioning hole.

[0018] Optionally, a rotating screw is provided on the rotating arm.

[0019] Secondly, this application provides a method of using a code pattern device, characterized in that it employs a code pattern device as described above, comprising:

[0020] Pull out the pin, push the rotating screw upward to rotate the rotating arm, and pull out the positioning pin;

[0021] Depending on the mold size, push the base inward to make it contact the limiting surface, or push the base outward to make it contact the limiting block.

[0022] Push the rotating screw downwards to reset the rotating arm, insert the positioning pin into the positioning hole, insert the pull pin, and complete the mold preparation;

[0023] Adjust the distance between the base plates and hoist the mold in;

[0024] As the mold descends to the base, its left and right sides contact the base, completing the positioning in the width direction.

[0025] The mold continues to fall until it contacts the slider or positioning block, completing the positioning in the height direction;

[0026] The locking clamping component presses the pressure plate firmly, completing the mold-forming process.

[0027] In summary, the code pattern device and its usage method provided in this application have at least the following beneficial effects:

[0028] First, install the base plate on the injection molding equipment. Install the clamping mechanism on the mounting position of the base plate. Push the rotating arm upward to move the positioning pin away from its current positioning hole, releasing the positioning. Adjust the position of the clamping mechanism by moving the base according to the mold size. Push the rotating arm downward to reset it, and the positioning pin is repositioned in another set of positioning holes, completing the mold preparation. Hoist the mold in, allowing it to fall between the clamping mechanisms. After the left and right sides of the mold contact the base, use T-blocks to position the mold in the width direction to prevent it from deviating, completing the width positioning. The mold continues to fall and contact the positioning components, completing the height positioning. The clamping mechanisms are then used on both sides. The platen presses the mold in the width direction to prevent it from deviating during production, completing the mold setup and saving mold change time. Operators no longer need to align the mold positioning ring with the equipment positioning holes, nor do they need to install multiple pressure plates around the mold. This reduces labor intensity, as operators no longer need to align the mold positioning ring with the equipment positioning holes, nor do they need to install multiple pressure plates on the top, bottom, left, and right of the mold. It also eliminates safety hazards, as operators do not need to enter the equipment or place pressure plates on top of the mold when fixing it. At the same time, the mold is positioned in the height direction by the positioning components, ensuring that the mold will not slide downwards or fall during frequent movement.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this application.

[0039] Please see Figures 1 to 6 This application exemplarily provides a code pattern device, comprising:

[0040] Base plate 1 is positioned opposite to the injection molding equipment;

[0041] The base plate 1 has mounting positions 3 arranged opposite each other in the width direction. The mounting positions 3 have guide rails 12 arranged opposite each other on both sides in the height direction for guiding. At least two sets of positioning holes are opened between the guide rails 12. The base plate 1 also has positioning components arranged opposite each other in the width direction for positioning the mold 2 in the height direction.

[0042] A clamping mechanism is provided on the mounting position 3 and is used to position and clamp the mold 2 in the width direction;

[0043] The clamping mechanism includes a base 22, with guide grooves 26 on both sides of the base 22 that cooperate with the guide rail 12. The base 22 can move along the guide rail 12 within the mounting position 3. A T-shaped block 18 is provided on the base 22. Pressure plates 23 are provided on both sides of the horizontal bar of the T-shaped block 18. Both the T-shaped block 18 and the pressure plates 23 extend out of the base 22 towards the mold 2. A rotating seat 17 and a positioning post 19 are provided on both sides of the vertical bar of the T-shaped block 18. A first mounting position is provided on the rotating seat 17, and a second mounting position is provided on the positioning post 19. A rotating arm 6 is provided on the first mounting position and the second mounting position. The rotating arm 6 is mounted on the first mounting position via a rotating pin 16. The rotating arm 6 can rotate around the rotating pin 16 as an axis. The positioning post 19 passes through the base 22 and contacts the bottom of the positioning hole. The rotating arm 6 is mounted on the second mounting position via a positioning pin 20.

[0044] Specifically, the rotating seat 17 is mounted on the base 22 by screws, and multiple screws are installed on the guide rail 12 to mount the guide rail 12 on the floor. The two guide rails 12 are arranged in parallel.

[0045] In this embodiment, the base plate 1 is first installed on the injection molding equipment, and the clamping mechanism is installed on the mounting position 3 of the base plate 1. The rotating arm 6 is pushed upward to drive the positioning pin 19 away from the current positioning hole, releasing the positioning. The base 22 is moved according to the size of the mold 2 to adjust the position of the clamping mechanism. The rotating arm 6 is pushed downward to reset the rotating arm 6, and the positioning pin 19 is repositioned in another set of positioning holes, completing the mold preparation. The mold 2 is hoisted in, allowing the mold 2 to fall between the clamping mechanisms. After the left and right sides of the mold 2 contact the base 22, the mold 2 is positioned in the width direction by the T-block 18 to prevent the mold 2 from deviating, completing the width direction positioning. The mold 2 continues to fall and contact the positioning components, completing the height direction positioning. Positioning is achieved by pressing the mold 2 from the width direction using the pressure plates 23 on both the left and right sides, preventing the mold 2 from deviating during production and completing the mold stacking. This saves mold change time, as operators do not need to align the mold positioning ring with the equipment positioning holes, nor do they need to install multiple pressure plates around the mold. This reduces labor intensity, as operators no longer need to align the mold positioning ring with the equipment positioning holes, nor do they need to install multiple pressure plates on the top, bottom, left, and right of the mold. It also eliminates safety hazards, as operators do not need to enter the equipment or place pressure plates on top of the mold when fixing it. At the same time, the mold is positioned in the height direction by the positioning components, ensuring that the mold will not slide downwards or fall during frequent movements.

[0046] It is worth noting that, due to the different dimensions of the mold base plate, the positioning holes and positioning components can be adaptively adjusted according to the actual mold dimensions. In this embodiment, please refer to... Figure 5Two types of molds 2 are provided, namely a 750mm wide mold 2 and a 600mm wide mold 2. The mold base plate 32 of the 750mm wide mold 2 has a positioning dimension of 375mm in the height direction and a positioning dimension of 750mm in the width direction. The mold base plate 32 of the 600mm wide mold 2 has a positioning dimension of 300mm in the height direction and a positioning dimension of 600mm in the width direction.

[0047] In this embodiment, please refer to Figures 1 to 3 The positioning components include a slide rail 15, a slider 14, and a positioning block 13. The slider 14 is movably mounted on the slide rail 15 and can move on the slide rail 15. The positioning block 13 is located below the slide rail 15. When positioning the 750mm wide mold 2, the sliders 14 on the base plate 1 move to the side of the slide rail 15 away from the mold 2. When the 750mm wide mold 2 falls to contact the positioning block 13, it also contacts the slider 14, completing the positioning in the height direction. When positioning the 600mm wide mold 2, the sliders 14 on the base plate 1 move to the side of the slide rail 15 closer to the mold 2. At this time, the positioning block 13 abuts against the slider 14. When the 600mm wide mold 2 falls to contact the slider 14, the positioning in the height direction is completed. Through the abutment between the positioning block 13 and the slider 14, the positioning block 13 supports the slider 14, preventing the slider 14 from loosening and ensuring that the mold 2 will not slide downward or fall during frequent movement.

[0048] In this embodiment, a limiting surface for limiting is provided on the mounting position 3, and a limiting block 11 for limiting is provided on the side of the mounting position 3 near the guide rail 12. The clamping mechanism can move along the guide rail 12 to make the base 22 contact the limiting surface or the base 22 contact the limiting block 11. When positioning the 750mm wide mold 2, the clamping mechanism on the base plate 1 is pushed outward until the base 22 contacts the limiting block 11. The positioning post 19 positions the clamping mechanism on a set of positioning holes near the limiting block 11. When positioning the 600mm wide mold 2, the clamping mechanism on the base plate 1 is pushed inward until the base 22 contacts the limiting surface. The positioning post 19 positions the clamping mechanism on a set of positioning holes away from the limiting block 11.

[0049] In this embodiment, a positioning pin 10 for positioning and a fixing member 9 for installation are provided on the limiting block 11. The limiting block 11 is positioned on the base plate 1 by the limiting pin 10, and the limiting block 11 is connected to the base plate 1 by the fixing member 9. Specifically, in this embodiment, the fixing member 9 is set as a fixing screw, and a fixing threaded hole is opened on the base plate 1. The fixing screw passes through the limiting block 11 and the fixing threaded hole in sequence to install the limiting block 11 on the base plate 1.

[0050] In this embodiment, please refer to Figure 4 and Figure 5The clamping mechanism also includes a mounting block 25, which is connected to the base plate 1. The bottom of the base 22 is provided with a mounting groove 31. The mounting block 25 and the mounting groove 31 are matched with each other. The clamping mechanism is installed on the base plate 1 by the cooperation of the mounting block 25 and the mounting groove 31. Specifically, in this embodiment, the mounting block 25 is a T-shaped structure and the mounting groove 31 is a T-shaped groove. A row of connecting holes is provided on the base plate 1 between two sets of positioning holes. The mounting block 25 is connected to the base plate 1 by screws, bolts and other connecting parts. The base 22 is connected to the mounting block 25 through the T-shaped groove. The structure of the mounting block 25 and the mounting groove 31 is not limited here.

[0051] In this embodiment, please refer to Figure 3 A clamping element 24 and a guide element 21 are mounted on the pressure plate 23. An elastic element is mounted on the clamping element 24. The base 22 has a first mounting hole 30 for mounting the elastic element and a second mounting hole 29 for mounting the guide element 21. The clamping element 24 passes through the pressure plate 23 and the elastic element in sequence to lock the pressure plate 23 onto the base 22. The pressure plate 23 has mounting holes for the elastic element and the clamping element 24. Before the mold 2 is hoisted in and positioned, the pressure plate 23 is not locked. The pressure plate 23 is connected to the base 22 via the guide element 21. After the mold 2 is hoisted and positioned, the mold base plate 32 is first limited in width by the T-block 18 to prevent the mold 2 from falling. The pressure plate 23 is adjusted and pressed onto the base 22 and the mold 2 by the locking clamping member 24, thereby clamping the mold 2 in the width direction. The elastic member can better press the pressure plate 23 onto the base 22. At the same time, it is easy to disassemble the pressure plate when changing the mold. Specifically, in this embodiment, the clamping member 24 is a clamping screw and the elastic member is a spring. This is not limited here.

[0052] In this embodiment, a U-shaped block 5 is also provided on the base 22, which surrounds the rotating arm 6. A pull pin 4 is inserted between any U-shaped block 5 and the rotating arm 6. The U-shaped block 5 is installed on the base 22 by screws, and the rotating arm 6 is fixed on the U-shaped block 5 by the pull pin 4 to prevent the rotating arm 6 from deviating. When it is necessary to push the rotating arm 6, the pull pin 4 can be pulled out to push the rotating arm 6. A limiting groove 28 matching the rotating arm 6 is also provided on the surface of the base 22 that contacts the rotating arm 6. The limiting groove 28 limits the rotating arm 6, so that when the rotating arm 6 is pushed down, the rotating arm 6 is not subjected to excessive force and collides with the base 22, which would cause damage to the rotating arm 6.

[0053] In this embodiment, a positioning pin 20 is provided between the positioning pin 19 and the rotating arm 6. The positioning pin 20 connects the positioning pin 19 and the rotating arm 6. A through hole 27 is provided on the base 22. The positioning pin 19 passes through the through hole 27 and contacts the positioning hole for positioning. When the rotating arm 6 rotates and rises, it drives the positioning pin 19 to rise synchronously away from the current positioning hole. After adjusting the position of the clamping mechanism, the rotating arm 6 is pushed down, which drives the positioning pin 19 to be positioned in another set of positioning holes.

[0054] In this embodiment, a rotating screw 7 is threaded through the rotating arm 6. The rotating screw 7 is installed on the rotating arm 6 through a rotating nut 8. By holding the rotating screw 7, the left and right rotating arms 6 can be pushed synchronously to quickly complete the position adjustment of the clamping mechanism.

[0055] In another embodiment, this application provides a method of using a code pattern device, employing the code pattern device as described above, including:

[0056] Pull out the pin 4, push the rotating screw 7 upward, drive the rotating arm 6 to rotate, and pull out the positioning pin 19;

[0057] According to the size of mold 2, push the base 22 inward so that the base 22 contacts the limiting surface, or push the base 22 outward so that the base 22 contacts the limiting block 11.

[0058] Push the rotating screw 7 downwards to reset the rotating arm 6, insert the positioning pin 19 into the positioning hole, insert the pull pin 4, and complete the preparation of the code;

[0059] Adjust the distance between the base plates 1, and hoist in the mold 2;

[0060] Between the time the mold 2 falls to the base plate 1 and the time the left and right sides of the mold 2 come into contact with the base 22, the positioning in the width direction is completed;

[0061] The mold 2 continues to fall until it contacts the slider 14 or the positioning block 13, thus completing the positioning in the height direction;

[0062] The locking clamping component 24 presses the pressure plate 23 tightly, completing the mold-forming process.

[0063] In summary, in the mold-forming device and its usage method provided in this application, the mold-forming device provided in this embodiment first installs the base plate 1 on the injection molding equipment, installs the clamping mechanism on the mounting position 3 of the base plate 1, pushes the rotating arm 6 upward to drive the positioning pin 19 away from the current positioning hole, releases the positioning, moves the base 22 according to the size of the mold 2 to adjust the position of the clamping mechanism, pushes the rotating arm 6 downward to reset the rotating arm 6, and the positioning pin 19 is repositioned in another set of positioning holes, completing the mold-forming preparation, hoists the mold 2, and lowers the mold 2 between the clamping mechanisms. After the left and right sides of the mold 2 contact the base 22, the T-block 18 positions the mold 2 in the width direction to prevent the mold 2 from deviating, completing the width direction positioning, and the mold 2 continues to descend. The mold 2 is positioned in height by contacting the positioning component. The left and right pressure plates 23 then press the mold 2 in width to prevent it from deviating during production, completing the mold setup and saving mold change time. Operators no longer need to align the mold positioning ring with the equipment positioning holes or install multiple pressure plates around the mold. This reduces labor intensity, as operators no longer need to align the mold positioning ring with the equipment positioning holes or install multiple pressure plates on the top, bottom, left, and right sides of the mold. It also eliminates safety hazards, as operators do not need to enter the equipment or place pressure plates on top of the mold when fixing it. Furthermore, the height positioning of the mold by the positioning component ensures that the mold will not slide downwards or fall during frequent movement.

[0064] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
