Description

Technical Field

[0001] This utility model relates to the field of mold guiding and positioning technology, and in particular to a high-precision injection mold guiding and positioning device. Background Technology

[0002] With the rapid development of society and the economy, the application range of injection molded parts is becoming increasingly wide. Injection molds are tools for producing plastic products, and also tools that give plastic products their complete structure and precise dimensions. In the field of injection mold manufacturing, guiding and positioning devices play a crucial role in ensuring the mold closing accuracy of injection molds and the molding quality of plastic products. As plastic products develop towards higher precision and complexity, the precision requirements for injection mold guiding and positioning devices are also increasing.

[0003] However, existing injection mold guide and positioning devices usually have a fixed structure, making it difficult to detect problems with the guide and positioning device in a timely manner when wear and misalignment occur, which can easily affect the accuracy of the injection mold. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a high-precision injection mold guiding and positioning device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a high-precision injection mold guiding and positioning device, including an upper mold base and a lower mold base for support. The upper mold base and the lower mold base are respectively provided with guide pillars and guide sleeves for guiding and positioning. One end of each guide pillar and guide sleeve is fixedly mounted with a mounting base for fixing and protecting it. The mounting base is provided with a detection ball for detecting the guide pillar and guide sleeve. Below and to the side of the detection ball are metal detection blocks for sensing its movement. One side of the metal detection block is provided with a laser detector for detecting its position. The laser detector is signal-connected to a microprocessor (STM32F103C8T6) for signal processing and automatic control. The microprocessor is signal-connected to an alarm.

[0006] Preferably, in any of the above solutions, the upper mold base and the lower mold base are provided with mounting grooves for fixing the mounting base, and one end of the guide post and the guide sleeve is provided with a calibration body made of metal and having a hemispherical structure.

[0007] The above technical solution employs the following: the mounting grooves of the upper and lower mold bases (made of P20 mold steel) provide a precise installation reference for the mounting base; the guide pillars (made of GCr15 bearing steel) and guide sleeves (made of GCr15 bearing steel with an inner diameter adapted to the guide pillars) provide guidance and positioning; the calibrator (made of 45# steel) fits against the detection ball to transmit the offset signals of the guide pillars and guide sleeves; the mold steel mold base has high rigidity, resists mold closing impact without deformation; the mounting grooves ensure the positioning accuracy of the mounting base and provide a stable reference for subsequent testing; the GCr15 guide pillars and guide sleeves are wear-resistant and corrosion-resistant; and the hemispherical calibrator fits tightly against the detection ball, which can synchronously transmit the slight offsets of the guide pillars and guide sleeves to the detection ball.

[0008] Preferably, in any of the above embodiments, the mounting base includes a connecting base for support and fixation and a shock-absorbing rubber ring for protection. The connecting base is fixedly installed inside the upper mold base and the lower mold base. The shock-absorbing rubber ring covering the guide post and guide sleeve is fixedly installed inside the connecting base. The shock-absorbing rubber ring is located on one side of the calibration body.

[0009] The above technical solution is adopted as follows: the connecting seat of the mounting base (aluminum alloy material) fixes the guide post and guide sleeve to the detection component, the shock-absorbing rubber ring (silicone rubber material) covers the root of the guide post and guide sleeve to absorb the mold closing vibration, the aluminum alloy connecting seat is lightweight and has moderate rigidity, balancing support and installation convenience, the silicone rubber shock-absorbing rubber ring buffers the impact of mold closing, avoids vibration causing false triggering of the detection component, the covering structure protects the root of the guide post and guide sleeve to prevent wear and corrosion, located on the side of the calibration body, does not affect the transmission of offset signal, and at the same time provides a stable working environment for the detection component.

[0010] Preferably, in any of the above embodiments, the detection sphere is made of magnetic material, and the detection sphere and the calibrator are in close contact.

[0011] The above technical solution involves a detection sphere (made of neodymium iron boron magnetic material) that is tightly fitted to a metal calibrator. This converts the offset of the guide post and sleeve into its own displacement, which is then magnetically attracted to the metal detection block for synchronous movement. The strong magnetic force of the neodymium iron boron magnetic material ensures the attraction force with the metal detection block, resulting in seamless displacement transmission. The sphere structure allows for multi-directional displacement, capturing any directional offset of the guide post and sleeve. The smooth surface reduces friction with the calibrator and detection block, preventing wear from affecting detection accuracy. The tight fit ensures the transmission of the offset signal without signal loss.

[0012] Preferably, in any of the above embodiments, the metal detection block includes a smooth pad for support and a metal sensing block. The smooth pad is movably connected to the interior of the connecting seat, and a sensing block that moves inside the connecting seat and is in contact with the detection ball is fixedly installed at one end of the smooth pad.

[0013] The above technical solution is as follows: the smooth pad (made of polytetrafluoroethylene) of the metal detection block slides along the connecting seat, the sensing block (made of ferromagnetic material) adheres to the detection sphere and moves synchronously with the sphere. The smooth pad of polytetrafluoroethylene has low sliding resistance, ensuring that the sensing block and the detection sphere move synchronously. The ferromagnetic sensing block is attracted by the magnetic force of the detection sphere and fits tightly without loosening. The cross is distributed below and to the side of the detection sphere to capture the offset in the X and Y directions, realizing all-round detection. The structural design is simple and easy to install and maintain.

[0014] Preferably, in any of the above embodiments, the laser detector includes a mounting base for mounting and dismounting and a laser rangefinder for detection. The mounting base is threaded into the interior of the connector, and the laser rangefinder for detecting the position of the smooth pad is fixedly installed inside the mounting base.

[0015] The above technical solution is adopted: the mounting base of the laser detector (made of stainless steel) enables the sensor to be detached and installed; the laser range sensor (triangular type) detects the displacement of the smooth pad in real time, and the data is transmitted to the microprocessor; the threaded mounting base facilitates sensor calibration and replacement; the laser range sensor has high precision and fast response, captures the minute displacement of the smooth pad, indirectly calculates the offset of the guide post and guide sleeve, and provides real-time data feedback, providing accurate basis for offset judgment and avoiding the deterioration of mold precision due to detection lag.

[0016] Preferably, in any of the above solutions, the alarm is fixedly installed at one end of the connecting base, and an alarm sound channel is provided on one side of the alarm located inside the upper mold base and the lower mold base.

[0017] The above technical solution is adopted: the alarm (audio-visual alarm) is fixed to the connector, receives the microprocessor signal to trigger the alarm, the alarm channel (a rectangular slot opened inside the mold base) enhances the sound propagation, and the dual sound and light alarm ensures that the operator can quickly detect the deviation abnormality. The high decibel sound combined with the alarm channel has high visibility in noisy workshop environments, and the high brightness light is intuitive and eye-catching. Fixed to the connector and close to the detection component, the alarm positioning is accurate and facilitates quick troubleshooting. The alarm channel does not affect the structural strength of the mold.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. A mounting base is installed at one end of the guide pillar and guide sleeve used for guiding and positioning inside the injection mold to fix them. A magnetic detection ball is installed inside the mounting base to detect the offset of the guide pillar and guide sleeve. The magnetic detection ball rotates synchronously with the guide pillar or guide sleeve when it is offset due to friction between itself and the guide pillar or guide sleeve. The magnetic effect causes the detection ball to drive the metal detection block to move. The amount of movement of the metal detection block is detected by a laser detector. By combining the detection data with the inherent dimensions, the offset of the guide pillar or guide sleeve can be quickly determined. This allows for timely and accurate detection of problems with the positioning and guiding device, facilitating subsequent processing and improving the accuracy of the injection mold.

[0019] 2. Metal detection blocks are arranged in a cross shape around the detection sphere at the bottom and sides, which facilitates the detection of the sphere's offset in two directions. The combination of detection data in two directions makes it easier to accurately determine the direction and amount of offset of the guide positioning device, thus improving the accuracy of offset detection.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figure 1-4As shown in the figure, a high-precision injection mold guiding and positioning device according to an embodiment of the present invention includes an upper mold base 1 and a lower mold base 2 for support. The upper mold base 1 and the lower mold base 2 are respectively provided with guide pillars 3 and guide sleeves 4 for guiding and positioning. One end of the guide pillars 3 and guide sleeves 4 is fixedly installed with a mounting base 5 for fixing and protecting them. The mounting base 5 is provided with a detection ball 6 for detecting the guide pillars 3 and guide sleeves 4. The detection ball 6 is provided with metal detection blocks 7 for sensing its movement below and to the side. A laser detector 8 is provided on one side of the metal detection block 7 for detecting its position. The laser detector 8 is connected to a microprocessor (STM32F103C8T6) for signal processing and automatic control. The microprocessor is connected to an alarm 9 for alarm function.

[0024] Preferably, in any of the above schemes, the upper mold base 1 and the lower mold base 2 are provided with mounting grooves for fixing the mounting base 5, and one end of the guide post 3 and the guide sleeve 4 is provided with a calibration body 10 made of metal and having a hemispherical structure.

[0025] The above technical solution is adopted: the mounting grooves of the upper mold base 1 and the lower mold base 2 (made of P20 mold steel) provide a precise installation reference for the mounting base 5. The guide post 3 (GCr15 bearing steel) and the guide sleeve 4 (GCr15 bearing steel, with an inner diameter adapted to the guide post) achieve guiding and positioning. The calibrator 10 (made of 45 steel) fits against the detection ball 6 to transmit the offset signal of the guide post and guide sleeve. The mold steel mold base has high rigidity and can resist the impact of mold closing without deformation. The mounting groove ensures the positioning accuracy of the mounting base 5 and provides a stable reference for subsequent testing. The GCr15 guide post and guide sleeve are wear-resistant and corrosion-resistant. The hemispherical calibrator 10 fits tightly against the detection ball 6 and can synchronously transmit the small offset of the guide post and guide sleeve to the detection ball.

[0026] The high-hardness mold base bears the clamping force and impact. The precise guiding principle is based on the precise fit of the guide pillars and guide sleeves, which limits the relative displacement of the mold base. The offset transmission principle is based on the tight fit between the calibrator and the detection ball, which converts the linear displacement into the angular displacement of the ball. The mounting base 5 is fixed in the mounting groove of the upper mold base 1 and the lower mold base 2. The calibrator 10 at one end of the guide pillar 3 and the guide sleeve 4 fits with the detection ball 6. When the mold is closed, the guide pillar 3 is inserted into the guide sleeve 4 to achieve guiding and positioning. When the guide pillar and guide sleeve are worn or offset, the calibrator 10 pushes the detection ball 6 to move synchronously. The dimensional accuracy of the mounting groove and the wear of the calibrator surface are checked regularly, and the guiding accuracy of the guide pillar and guide sleeve is tested regularly.

[0027] Preferably, in any of the above embodiments, the mounting base 5 includes a connecting base 51 for support and fixation and a shock-absorbing rubber ring 52 for protection. The connecting base 51 is fixedly installed inside the upper mold base 1 and the lower mold base 2. The shock-absorbing rubber ring 52 covering the guide post 3 and the guide sleeve 4 is fixedly installed inside the connecting base 51. The shock-absorbing rubber ring 52 is located on one side of the calibration body 10.

[0028] The above technical solution is adopted: the connecting seat 51 (aluminum alloy material) of the mounting base 5 fixes the guide post and guide sleeve and the detection component; the shock-absorbing rubber ring 52 (silicone rubber material) covers the root of the guide post and guide sleeve to absorb the mold closing vibration; the aluminum alloy connecting seat is lightweight and has moderate rigidity, balancing support and installation convenience; the silicone rubber shock-absorbing rubber ring buffers the impact of mold closing and avoids the detection component from being falsely triggered by vibration; the covering structure protects the root of the guide post and guide sleeve to prevent wear and corrosion; it is located on one side of the calibrator 10 and does not affect the transmission of offset signal, while providing a stable working environment for the detection component.

[0029] The connecting seat secures each component through a mechanical structure, ensuring precise positioning. The shock absorption and buffering principle is based on the elastic deformation of silicone rubber to absorb vibration energy. The protection principle is based on the covering structure of the rubber ring to isolate impurities and moisture. The connecting seat 51 is installed in the mold base mounting slot. The guide post and guide sleeve are inserted into the connecting seat and fixed. The shock-absorbing rubber ring 52 covers the root of the guide post and guide sleeve. When the mold is closed, the rubber ring compresses and deforms to absorb vibration. When the guide post and guide sleeve shift, the vibrating rubber ring does not hinder the displacement transmission of the calibrator and the detection ball. The surface of the connecting seat and the rubber ring should be cleaned regularly (to ensure no impurities adhere). The aging condition of the rubber ring should be checked regularly.

[0030] Preferably, of any of the above schemes, the detection sphere 6 is made of magnetic material, and the detection sphere 6 and the calibrator 10 are in close contact.

[0031] The above technical solution is adopted: the detection sphere 6 (neodymium iron boron magnetic material) is closely attached to the metal calibrator 10, converting the offset of the guide post and guide sleeve into its own displacement. The metal detection block 7 is moved synchronously by magnetic adsorption. The strong magnetic force of the neodymium iron boron magnetic material ensures the adsorption force with the metal detection block 7. The displacement transmission is lag-free. The sphere structure can realize multi-directional displacement, capturing the offset of the guide post and guide sleeve in any direction. The smooth surface reduces friction with the calibrator and detection block, avoiding wear that affects the detection accuracy. The close fit ensures the transmission of offset signal without signal loss.

[0032] Magnetic force ensures synchronous displacement of the detection sphere and the metal detection block. The multi-directional transmission principle is based on the geometry of the sphere, adapting to offsets in any direction. The low-friction principle is based on a smooth surface, reducing displacement resistance. The detection sphere 6 is placed inside the connecting seat 51 and naturally fits with the calibrator 10. When the guide post and guide sleeve are offset, the calibrator 10 pushes the detection sphere 6 to move. The sphere drives the metal detection block 7 to move synchronously through magnetic force. The laser detector 8 captures the displacement of the detection block in real time. The surface of the sphere is cleaned regularly (to prevent the adsorption of magnetic impurities) and the magnetic force attenuation of the sphere is checked regularly.

[0033] Preferably, in any of the above embodiments, the metal detection block 7 includes a smooth pad 71 for support and a metal sensing block 72. The smooth pad 71 is movably connected to the inside of the connecting seat 51, and the sensing block 72, which moves inside the connecting seat 51 and is in contact with the detection ball 6, is fixedly installed at one end of the smooth pad 71.

[0034] The above technical solution is adopted: the smooth pad 71 (made of polytetrafluoroethylene) of the metal detection block 7 slides along the connecting seat 51, the sensing block 72 (made of ferromagnetic material) is attached to the detection ball 6 and moves synchronously with the ball. The smooth pad of polytetrafluoroethylene has low sliding resistance, ensuring that the sensing block 72 moves synchronously with the detection ball 6. The ferromagnetic sensing block 72 is attracted by the magnetic force of the detection ball and fits tightly without loosening. It is distributed in a cross shape below and to the side of the detection ball to capture the offset in the X and Y directions, realizing all-round detection. The structural design is simple and easy to install and maintain.

[0035] The low friction of polytetrafluoroethylene reduces displacement resistance. The magnetic bonding principle is based on the magnetic attraction between the sensing block and the detection ball, ensuring synchronous action. The omnidirectional detection principle is based on a cross distribution, covering the main offset directions. The smooth pad 71 is installed in the slide groove of the connecting seat 51. The sensing block 72 is fixed to one end of the pad and adheres to the detection ball 6. When the detection ball 6 is displaced, the magnetic force drives the sensing block 72 and the smooth pad 71 to slide along the slide groove. The laser detector 8 detects the position of the pad in real time. The slide groove and the surface of the pad are cleaned regularly (to prevent impurities and jamming). The sliding resistance and the tightness of the adhesion are tested regularly.

[0036] Preferably, in any of the above embodiments, the laser detector 8 includes a mounting base 81 for mounting and dismounting and a laser rangefinder 82 for detection. The mounting base 81 is threadedly connected to the inside of the connecting base 51, and the laser rangefinder 82 for detecting the position of the smooth pad 71 is fixedly installed inside the mounting base 81.

[0037] The above technical solution is adopted: the mounting base 81 (made of stainless steel) of the laser detector 8 enables the sensor to be detached and installed; the laser range sensor 82 (triangular type) detects the displacement of the smooth pad 71 in real time and transmits the data to the microprocessor; the threaded mounting base facilitates sensor calibration and replacement; the laser range sensor has high precision and fast response, captures the small displacement of the smooth pad, indirectly calculates the offset of the guide post and guide sleeve, and provides real-time data feedback, providing accurate basis for offset judgment and avoiding the deterioration of mold precision due to detection lag.

[0038] The threaded structure of the mounting base ensures the installation accuracy of the sensor. The laser ranging principle is based on light reflection to calculate the distance and convert it into displacement data. The signal transmission principle is based on the communication between the sensor and the microprocessor to realize real-time data interaction. The mounting base 81 is threaded to the connecting base 51. The laser ranging sensor 82 is aligned with the smooth pad 71. After the sensor is started, it collects position data periodically. When the smooth pad moves, the sensor feeds back the data to the microprocessor in real time. The sensor accuracy is calibrated periodically, and the tightness of the mounting base threads and the cleanliness of the sensor lens are checked periodically. The sensor data is transmitted to the microprocessor through the ADC interface. The data is processed using a digital filtering algorithm to reduce vibration interference.

[0039] Preferably, of any of the above solutions, the alarm 9 is fixedly installed at one end of the connecting base 51, and an alarm sound channel located inside the upper mold base 1 and the lower mold base 2 is provided on one side of the alarm 9.

[0040] The above technical solution is adopted: the alarm 9 (audio-visual alarm) is fixed to the connector 51, receives the microprocessor signal to trigger the alarm, the alarm channel (a rectangular slot opened inside the mold base) enhances the sound propagation, and the dual sound and light alarm ensures that the operator can quickly detect the deviation abnormality. The high decibel sound combined with the alarm channel has high visibility in noisy workshop environments, and the high brightness light is intuitive and eye-catching. Fixed to the connector 51, close to the detection component, the alarm positioning is accurate and it is convenient to quickly troubleshoot the problem. The alarm channel does not affect the structural strength of the mold.

[0041] The dual stimulation of sound and light enhances the alarm effect. The sound enhancement principle is based on the guiding effect of the alarm channel to reduce sound diffusion. The precise positioning principle is based on the close installation of the alarm and the detection component to clearly identify the abnormal location. The alarm 9 is fixed to one end of the connector 51, and the alarm channel is aligned with the alarm sound outlet. When the microprocessor determines that the guide post and guide sleeve offset exceeds the threshold, it outputs a signal to trigger the alarm, and the sound and light are activated simultaneously, prompting the operator to stop the machine for inspection. After the fault is eliminated, the alarm is reset. The sound and light intensity of the alarm is tested regularly, and the patency of the alarm channel is checked regularly. The alarm trigger threshold is set by the microprocessor parameters.

[0042] The working principle of this high-precision injection mold guiding and positioning device is as follows: The upper mold base 1 and the lower mold base 2 are precisely fixed to the mounting base 5 through the mounting groove. The connecting seat 51 of the mounting base 5 fixes the guide post 3 and the guide sleeve 4. The silicone rubber shock-absorbing ring 52 covers the root of the guide post and guide sleeve to absorb the mold closing vibration and prevent the detection component from being triggered erroneously. When the mold is closed, the guide post 3 is inserted into the guide sleeve 4 to achieve guidance and positioning. The metal hemispherical calibrator 10 at one end of the guide post and guide sleeve is in close contact with the magnetic detection ball 6. If the guide post and guide sleeve are displaced due to wear or offset, the calibrator 10 will push the detection ball 6 to move synchronously. The ball will magnetically attract the sensing block 72 of the metal detection block 7, which will drive the polytetrafluoroethylene smooth pad 71 to slide along the slide groove of the connecting seat 51. The mounting and dismounting seat 81 of the laser detector 8 fixes the laser ranging sensor 82 to detect the displacement of the smooth pad 71 in real time. The data is transmitted to the microprocessor. The microprocessor calculates the displacement and derives the offset of the guide post and guide sleeve. If the threshold is exceeded, the alarm 9 at one end of the connecting seat 51 will be triggered immediately. The alarm sound channel will amplify the sound propagation to prompt the operator to stop the machine for inspection.

[0043] Compared with the prior art, the present invention has the following advantages: 1. A mounting base 5 is provided at one end of the guide post 3 and guide sleeve 4, which are used for guiding and positioning inside the injection mold, to install and fix them. A magnetic detection ball 6 is set inside the mounting base 5 to detect the offset of the guide post 3 and guide sleeve 4. The magnetic detection ball 6 can rotate synchronously when the guide post 3 or guide sleeve 4 is offset due to friction between it and the guide post 3 or guide sleeve 4. The magnetic effect causes the detection ball 6 to drive the metal detection block 7 to move. The amount of movement of the metal detection block 7 is detected by a laser detector 8. The offset of the guide post 3 or guide sleeve 4 can be quickly determined by combining the detection data with the inherent dimensions. This allows for timely and accurate detection of problems with the positioning and guiding device, facilitating subsequent processing and improving the accuracy of the injection mold.

[0044] 2. The metal detection blocks 7 are arranged in a cross shape around the detection sphere 6 at the bottom and side, which facilitates the detection of the offset of the detection sphere 6 in two directions. The combination of the detection data in two directions makes it easier to accurately determine the direction and amount of the offset of the guide positioning device, thereby improving the accuracy of offset detection.
