Description

Technical Field

[0001] The invention relates to the technical field of injection molding, and in particular to a clamping structure of a spray pump head injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. The use of injection molding machines is relatively wide. At present, the end joints of the winding structure wall pipe used for drainage are also made by injection molding machines. The locking structure includes a mold and a locking ring. The locking ring can perform injection molding after locking the mold. Therefore, the injection molding machine needs a locking structure to lock it during injection molding. However, displacement occurs during locking work, which affects the injection molding of the mold, reduces the sealing of the mold during injection molding, and causes leakage during raw material injection molding. In addition, the mold is prone to not being locked in place during locking, resulting in deviations in the locking position of the locking structure, which makes the locking structure insufficiently stressed during locking, reducing the efficiency of mold injection molding. The locking structure is not easy to position when it moves, which makes it easy to deviate during movement, and it is not easy to control the moving range of the locking structure.

[0003] To sum up, displacement occurs during the locking work, which affects the injection molding of the mold and reduces the sealing of the mold during injection molding. In addition, the mold is easily not locked in place during the locking process, which makes the locking structure insufficiently stressed during locking, reducing the work efficiency of the mold injection molding. Summary of the invention

Two mounting frames are arranged on the locking ring through the mounting frame, and the two mounting frames are installed opposite to each other. The inner surface of the mounting frame is fixedly connected to a locking cylinder, and one end of the locking cylinder close to the locking ring is fixedly connected to a locking block.

[0005] By installing the base on the injection molding machine, the molding die and the mold are installed relative to each other, and as the mold moves horizontally until it contacts the docking sleeve, it stops, and the mold passes through the docking sleeve and is sealed with the mounting plate. As the molding die and the mold are sealed, injection molding is performed. When the mold moves to the inside of the locking ring, the micro motor drives the screw to rotate clockwise inside the mounting plate, so that the rotation of the screw drives the locking ring to move toward a position close to the mounting plate, and the locking ring moves along the guide rod and the screw with the mold. When the mold stops moving, the locking ring stops together, and the mounting frame fixes the locking cylinder on the locking ring, so that the locking cylinder extends and pushes the locking block to move to lock the stopped mold. When the locking block moves, it moves along the locking ring, so that the locking ring cooperates with the locking block to perform locking work. After the injection molding is completed, the locking cylinder contracts and drives the locking block away from the mold, and the screw rotates counterclockwise, so that the screw drives the locking ring to move away from the mounting plate, thereby loosening the lock of the mold.

[0006] Preferably, the outer surface of the locking block is slidably connected to the locking ring, and one end of the screw rod away from the locking ring is rotatably connected to the mounting plate.

[0011] Preferably, the inner surface of the inner ring is fixedly connected with a support sleeve, the bottom end of the support sleeve is fixedly connected with a fixed plate, the inner surface of the support sleeve is fixedly connected with a limiting plate, and the limiting plates are distributed in a circular shape on the support sleeve; The partition frame is fixedly connected to a position of the support sleeve close to the limiting plate, and a receiving plate is fixedly connected to the top of the partition frame.

[0012] When the locking ring moves toward the mounting plate and contacts the protective block through the blocking plate, the protective block squeezes the elastic plate, causing the elastic plate to contract on the blocking plate, so that the movement of the locking ring gradually stops; when the locking ring moves away from the protective block, the elastic plate stretches and pushes the protective block to reset, and the blocking plate is subjected to vibration and transmitted to the protective cylinder, so that the movable frame inside the protective cylinder is subjected to the vibration force to drive the purification cylinder to rotate, so that the purification cylinder purifies the gas inside the protective cylinder; the fixed plate supports the supporting sleeve inside the protective cylinder, so that the inner ring on the supporting sleeve is connected to the protective cylinder, and the partition frame fixes the receiving plate inside the supporting sleeve, so that the receiving plate is horizontally set to receive fallen impurities; as the limiting plate contacts the rotating purification cylinder inside the support sleeve, the limiting plate knocks when it contacts the purification cylinder, and the purification cylinder rotates in the opposite direction due to the restriction of the limiting plate.

[0013] Preferably, the top of the limiting plate extends to the outside of the supporting sleeve, and the bottom of the fixing plate is fixedly connected to the protective tube.

[0014] Preferably, the contact assembly includes an abutment plate, the abutment plate is fixedly connected to the bottom of the inner cavity of the base, the top of the abutment plate is fixedly connected to a lap plate, the position of the abutment plate close to the lap plate is fixedly connected to a positioner frame, the inner cavity bottom of the positioner frame is fixedly connected to a positioner, and the position of the abutment plate away from the lap plate is fixedly connected to an assembly plate; A connecting tube is fixedly connected to the top of the abutment plate, and is located between the assembly plate and the lap plate on the abutment plate through the connecting tube.

[0016] Preferably, the top of the assembly plate is rotatably connected to an auxiliary frame, and the assembly plate is rotatably connected to a movable plate at a position away from the auxiliary frame, and is located between the two movable plates through the auxiliary frame; A support block is fixedly connected to the top of the auxiliary frame inner cavity, the outer surface of the support block is fixedly connected to an external plate, the bottom of the external plate is fixedly connected to a telescopic rod, which extends to the outside of the base through the top of the telescopic rod, and the bottom end of the telescopic rod is fixedly connected to the assembly plate.

[0017] The lap plate and the connecting tube are supported inside the base by the abutment plate, so that the contact plate contacts the locking ring on the reset column. As the contact plate and the locking ring are separated, the reset column rises inside the connecting tube. When the locking ring contacts the contact plate, the contact plate squeezes the reset column and descends inside the connecting tube. The lap plate rotates the installation position of the locator frame on the abutment plate, so that the locator on the locator frame positions the movement of the locking ring, so that the locking ring moves to the reset stop when the locator senses it, and the assembly plate fixes the movable plate and the auxiliary frame on the abutment plate, so that the movable plate is vibrated and swings on the assembly plate, thereby adjusting the movable plate, and as the support block supports the auxiliary frame, the auxiliary frame is vertically installed on the assembly plate, and the external plate fixes the telescopic rod on the support block, so that the telescopic rod extends out of the base and contacts the locking ring, so that when the locking ring moves to contact the telescopic rod, the telescopic rod is pressed to shrink, and the contact between the telescopic rod and the locking ring is used to tighten.

[0018] The present invention provides a clamping structure for a spray pump head injection molding machine. It has the following beneficial effects: The clamping structure of the injection molding machine for the spray pump head is provided with a mounting plate, a docking sleeve, and a protective component. The mounting plate contacts the molding die on the base, so that the mounting plate can play a separating role on the molding die, so that the mounting plate and the docking sleeve cooperate to seal the contact position between the molding die and the mold. The protective component connects the base and the mounting plate, so that the protective component cooperates with the molding die to limit the position of the mounting plate, so that when the protective component is subjected to the pressure of the locking component, it can be buffered, so that the protective component can protect the locking component to prevent the locking component from being damaged by collision during the locking operation, thereby ensuring the accuracy of the locking operation of the locking component.

[0019] The clamping structure of the injection molding machine for the spray pump head is driven by a micro motor to rotate on a mounting plate, so that the position of the locking ring is adjusted by the rotation of the screw, so that the locking ring plays a guiding role when moving on the screw, and the guide rod cooperates with the screw on the mounting plate, so that the locking ring moves along the guide rod and the screw, thereby ensuring the stability of the locking ring during movement, ensuring that the locking ring is not easily stuck due to uneven force when moving, and the cooperation between the guide rod and the screw can increase the bearing capacity of the locking ring itself.

[0020] The clamping structure of the injection molding machine for the spray pump head can increase the contact area by connecting the mounting frame with the locking ring, so that the connection position of the locking ring is not easily affected, the stability of the mounting frame on the locking ring is ensured, and the mounting frame is prevented from falling off the locking ring. The locking block is pushed by the extension of the locking cylinder to contact the mold, so that the locking cylinder adjusts the locking position as the locking ring moves, so that the locking block is convenient to cooperate with the locking ring for locking during injection molding.

[0021] The locking structure of the injection molding machine for the spray pump head can separate the mounting plate and the locking ring on the base through a blocking plate, so that the blocking plate can limit the moving distance of the locking ring, thereby avoiding collision between the locking ring and the mounting plate when the locking ring moves. The protective block is pressed against the elastic plate by the pressure of the locking ring, so that the elastic plate contracts to support the protective block, so that the elastic plate can protect the protective block with its own elastic force when it contracts, thereby preventing the protective block from breaking when it contacts the locking ring.

[0022] The clamping structure of the injection molding machine for the spray pump head is subjected to the vibration force transmitted by the blocking plate inside the protective cylinder through the movable frame, so that the movable frame rotates to drive the purification cylinder to move, thereby adjusting the reinforcement of the purification cylinder. The purification cylinder can rotate inside the protective cylinder, so that the purification cylinder rotates to adjust the reinforcement of the purification. A reset spring is provided at the top of the purification cylinder, so that the reset spring can drive the purification cylinder to reset, thereby increasing the bearing capacity of the protective cylinder itself.

[0023] The clamping structure of the injection molding machine for the spray pump head supports the support sleeve inside the protective tube through the fixed plate, so that the fixed plate and the support sleeve cooperate to tighten the inner ring, so that the connection position of the inner ring on the protective tube is not easy to loosen, and the connection position of the support sleeve and the fixed plate is not easy to move. The limiting plate is distributed in a circular shape on the support sleeve, so that the limiting plate can limit the rotation of the purification tube, and it is convenient for the limiting plate to knock when contacting the purification tube to prevent the purification tube from being affected when working inside the protective tube.

[0024] The clamping structure of the injection molding machine for the spray pump head fixes the lap plate, the assembly plate and the connecting tube inside the base through the abutment plate, thereby increasing the firmness of the abutment plate on the base and preventing the abutment plate from being displaced inside the base to cause a change in the contact position. The lap plate limits the installation position of the locator frame on the abutment plate, so that the lap plate is installed around the locator frame, which makes it easier for the locator on the locator frame to position the locking ring, and the lap plate is used to protect the locator frame on the abutment plate.

[0025] The clamping structure of the injection molding machine for the spray pump head can increase the contact area by cooperating with the connecting tube and the reset column, so that the reset column extends out of the base, and the connecting tube can guide the movement of the reset column. The contact plate can contact the locking ring when the reset column is raised and lowered, so that the contact plate can provide auxiliary support for the locking ring, thereby increasing the bearing capacity of the locking ring itself, making it easier for the contact plate to contact the locking ring for positioning, and when the contact plate is separated from the locking ring, it is easier for the contact plate to block the movement of the locking ring.

[0026] The clamping structure of the injection molding machine for the spray pump head supports the movable plate on the abutment plate through the assembly plate, which is convenient for the movable plate to swing on the assembly plate to adjust the contact position, thereby ensuring the stability of the connection position of the assembly plate and preventing the connection position with the abutment plate from becoming loose and affecting the swing of the movable plate. The auxiliary frame is supported by the support block on the assembly plate, thereby increasing the bearing capacity of the auxiliary frame itself, keeping the auxiliary frame installed vertically, and avoiding contact between the two movable plates when swinging.

[0027] The clamping structure of the injection molding machine for the spray pump head is installed horizontally on the support block through an external plate, so that the external plate fixes the telescopic rod, which is convenient for the vertical installation of the telescopic rod, and ensures that the support block and the external plate cooperate with each other. The telescopic rod is extended and retracted on the assembly plate under the pressure of the locking ring, so that the telescopic rod is extended and retracted to cooperate with the contact plate to support the locking ring, thereby increasing the stability of the locking ring when it stops moving, and preventing the locking ring from moving too far away from the installation plate.

The locking position of the locking component 4 is positioned by using the contact between the protective component 5 and the locking component 4, so that the locking component 4 is not easily moved during the locking operation. The locking assembly 4 is fixedly connected to the bottom of the inner cavity of the base 1 with a contact assembly 6, which is inside the base 1 so that the contact assembly 6 can support the locking assembly 4 that is not locked, so that the contact assembly 6 can keep the locking assembly 4 installed horizontally, avoiding the locking assembly 4 from being offset and causing a collision when the mold moves, affecting the contact between the subsequent mold and the forming mold 2, so that the locking assembly 4 can maintain its own locking effect after moving, and preventing the locking assembly 4 from being insufficiently stressed when locking, resulting in a loose locking. The locking assembly 4 includes a guide rod 46, which is fixedly connected to a side of the mounting plate 3 away from the forming mold 2. The guide rod 46 cooperates with the screw 41 on the mounting plate 3 to make the locking ring 45 move along the guide rod 46 and the screw 41, thereby ensuring the stability of the locking ring 45 during movement, ensuring that the locking ring 45 is not easily stuck due to uneven force when moving, and the guide rod 46 and the screw 41 cooperate with each other to support different positions of the locking ring 45, so that the guide rod 46 and the screw 41 can limit the installation position of the locking ring 45, so that the guide rod 46 cooperates with the screw 41 to increase the bearing capacity of the locking ring 45 itself, and the outer The surface is slidably connected with a locking ring 45, and the inner surface of the locking ring 45 is rotatably connected with a screw 41.

Two mounting frames are arranged on the locking ring 45 through the mounting frame 44, so that the mounting frame 44 fixes the locking cylinder 42, which is convenient for the locking cylinder 42 to remain horizontal on the mounting frame 44, so that the mounting frame 44 is used to fix the locking cylinder 42 while protecting it. The connection between the mounting frame 44 and the locking ring 45 can increase the contact area, so that the connection position of the locking ring 45 is not easily affected, ensuring the stability of the mounting frame 44 on the locking ring 45 and preventing the mounting frame 44 from falling off the locking ring 45. The inner surface of the mounting frame 44 is fixedly connected with the locking cylinder 42. The locking block 43 is fixedly connected to one end of the locking cylinder 42 close to the locking ring 45. The locking block 43 is pushed by the extension of the locking cylinder 42 to contact the mold, so that the locking cylinder 42 can adjust the locking position as the locking ring 45 moves, so that the locking block 43 cooperates with the locking ring 45 for locking during injection molding. The locking block 43 adjusts its position as the locking cylinder 42 extends and retracts, so that the locking force is adjusted by using the locking cylinder 42 to push the locking block 43 to move, thereby preventing the locking block 43 from loosening during locking work and causing leakage of the injection molding material, thereby ensuring the locking force of the locking block 43 under the push of the locking cylinder 42.

The impurities adhering to the surface of the purification cylinder 55 can be cleaned by knocking the purification cylinder 55 with the limiting plate 510, thereby ensuring the cleanliness of the purification cylinder 55 itself and preventing the purification cylinder 55 from being affected when working inside the protective cylinder 51.

The top of the abutment plate 61 is fixedly connected with a lap plate 62. The lap plate 62, the assembly plate 67 and the connecting tube 64 are fixed inside the base 1 by the abutment plate 61, so that the abutment plate 61 protects them, thereby increasing the firmness of the abutment plate 61 on the base 1 and preventing the abutment plate 61 from being displaced inside the base 1 to cause the contact position to change. The abutment plate 61 is inside the base 1 and the abutment plate 61 is located below the locking ring 45, so that the abutment plate 61 corresponds to the position when the locking ring 45 is not locked. The abutment plate 61 is close to the base 1. A locator frame 63 is fixedly connected to the position near the lap plate 62, and the lap plate 62 limits the installation position of the locator frame 63 on the abutment plate 61, so that the lap plate 62 is installed around the locator frame 63, so that the locator on the locator frame 63 can locate the locking ring 45, and the locking ring 45 stops when it moves to the position sensed by the locator, ensuring that the locking ring 45 is firmly locked. The lap plate 62 is used to protect the locator frame 63 on the abutment plate 61, so that the locator on the locator frame 63 corresponds to the locking ring 45, and the abutment plate 61 is fixedly connected to the assembly plate 67 away from the lap plate 62; The connecting tube 64 is fixedly connected to the top of the abutment plate 61. The connecting tube 64 is located between the assembly plate 67 and the lap plate 62 on the abutment plate 61, so that the connecting tube 64 protects the reset column 65. A spring is provided between the connecting tube 64 and the reset column 65, so that the reset column 65 moves inside the connecting tube 64 to stretch the spring, so that the expansion and contraction of the spring can drive the reset column 65 to reset. The connecting tube 64 cooperates with the reset column 65 to increase the contact area, so that the reset column 65 extends out of the base 1, so that the connecting tube 64 guides the movement of the reset column 65. The bottom of the inner cavity of the connecting tube 64 is rotatably connected with the reset column 65, and the reset column 65 is reset. A contact plate 66 is fixedly connected to the outer surface of the column 65, and the contact plate 66 can contact the locking ring 45 when the reset column 65 is raised or lowered, so that the contact plate 66 provides auxiliary support for the locking ring 45, thereby increasing the bearing capacity of the locking ring 45 itself, and the contact plate 66 is subjected to the pressure of the locking ring 45 to drive the reset column 65 to descend, so that the movement of the contact plate 66 and the reset column 65 can adjust the locking ring 45, and the contact plate 66 contacts the locking ring 45 for positioning. When the contact plate 66 is separated from the locking ring 45, the spring pushes the reset column 65 to rise, so that the reset column 65 drives the contact plate 66 to rise, so that the contact plate 66 can block the movement of the locking ring 45.

[0040] The top end of the reset column 65 extends to the outside of the connecting tube 64 , and the bottom of the assembly plate 67 penetrates the abutting plate 61 .

[0041] The top of the assembly plate 67 is rotatably connected with an auxiliary frame 68, and the assembly plate 67 supports the movable plate 69 on the abutment plate 61, so that the movable plate 69 swings when it is subjected to the vibration force transmitted by the base 1, so that the movable plate 69 swings on the assembly plate 67 to adjust the contact position, so that the assembly plate 67 is fixed when the movable plate 69 moves to contact the connecting tube 64 and the base 1, thereby ensuring the stability of the connection position of the assembly plate 67, and the movable plate 69 can be used to position its connection position to prevent the loose connection position with the abutment plate 61 from affecting the swing of the movable plate 69, and the assembly plate 67 A movable plate 69 is rotatably connected to a position away from the auxiliary frame 68. The auxiliary frame 68 is supported by the support block 610 on the assembly plate 67, thereby increasing the bearing capacity of the auxiliary frame 68 itself and keeping the auxiliary frame 68 vertically installed. The auxiliary frame 68 is located between the two movable plates 69, so that the auxiliary frame 68 cooperates with the connecting tube 64 to separate the two movable plates 69, thereby limiting the swing of the movable plates 69 and preventing the two movable plates 69 from contacting each other when swinging. The auxiliary frame 68 can protect the support block 610, so that the connection position between the auxiliary frame 68 and the support block 610 is not easy to loosen; The support block 610 is fixedly connected to the top of the inner cavity of the auxiliary frame 68. The outer surface of the support block 610 is fixedly connected with an external plate 612, which is horizontally installed on the support block 610 through the external plate 612, so that the external plate 612 fixes the telescopic rod 611, which is convenient for the vertical installation of the telescopic rod 611, so that the connection between the external plate 612 and the support block 610 can limit the telescopic rod 611, thereby increasing the contact area of ​​the support block 610 by using the external plate 612, and the position where the external plate 612 passes through the auxiliary frame 68 can play a positioning role in the installation of the support block 610, ensuring that the support block 610 and the external plate 612 cooperate with each other, and the external plate 612 can be installed. A telescopic rod 611 is fixedly connected to the bottom of the plate 612. The telescopic rod 611 is retracted and extended on the assembly plate 67 by the pressure of the locking ring 45, so that the telescopic rod 611 is retracted and extended to cooperate with the contact plate 66 to support the locking ring 45, thereby increasing the stability of the locking ring 45 when it stops moving. The telescopic rod 611 and the contact plate 66 can be used to fix different positions of the locking ring 45. The telescopic rod 611 is extended when separated from the locking ring 45, so that the telescopic rod 611 and the contact plate 66 cooperate to intercept the locking ring 45, preventing the locking ring 45 from moving too far away from the mounting plate 3. The bottom end of the telescopic rod 611 is fixedly connected to the assembly plate 67.

[0042] Example 2, please refer to Figure 1-Figure 12On the basis of Example 1, the present invention provides a technical solution: a method for using a clamping structure of a spray pump head injection molding machine, step 1: installing the base 1 on the injection molding machine, so that the molding mold 2 and the mold are relatively installed, and the mold stops when it moves horizontally to contact the docking sleeve 7, so that the mold passes through the docking sleeve 7 and is sealed with the mounting plate 3, and the injection molding work is performed when the molding mold 2 and the mold are sealed. When the mold moves to the inside of the locking ring 45, the micro motor drives the screw 41 to rotate clockwise inside the mounting plate 3, so that the screw 41 rotates and drives the locking ring 45 to move to a position close to the mounting plate 3; Step 2: Use the locking ring 45 to move along the guide rod 46 and the screw 41 with the mold, so that when the mold stops moving, the locking ring 45 stops together, and the mounting frame 44 fixes the locking cylinder 42 on the locking ring 45, so that the locking cylinder 42 extends and pushes the locking block 43 to move to lock the stopped mold. When the locking block 43 moves, it moves along the locking ring 45, so that the locking ring 45 and the locking block 43 cooperate to perform the locking work. After the injection molding is completed, the locking cylinder 42 contracts and drives the locking block 43 away from the mold, and the screw 41 rotates counterclockwise, so that the screw 41 drives the locking ring 45 to move away from the mounting plate 3, thereby loosening the lock of the mold; Step 3: The abutment plate 61 supports the lap plate 62 and the connecting tube 64 inside the base 1, so that the contact plate 66 contacts the locking ring 45 on the reset column 65. As the contact plate 66 separates from the locking ring 45, the reset column 65 rises inside the connecting tube 64. When the locking ring 45 contacts the contact plate 66, the contact plate 66 squeezes the reset column 65 to descend inside the connecting tube 64. The lap plate 62 rotates the installation position of the positioner frame 63 on the abutment plate 61, so that the positioner on the positioner frame 63 positions the movement of the locking ring 45, so that the locking ring 45 moves to reset and stops when the positioner senses it. Step 4: Fix the movable plate 69 and the auxiliary frame 68 on the abutment plate 61 through the assembly plate 67, so that the movable plate 69 is vibrated and swings on the assembly plate 67, thereby adjusting the movable plate 69, and the auxiliary frame 68 is supported by the support block 610, so that the auxiliary frame 68 is vertically installed on the assembly plate 67, and the external plate 612 fixes the telescopic rod 611 on the support block 610, so that the telescopic rod 611 extends out of the base 1 and contacts the locking ring 45, so that when the locking ring 45 moves to contact the telescopic rod 611, the telescopic rod 611 is pressed to contract, and the contact between the telescopic rod 611 and the locking ring 45 is used to tighten; Step 5: When the blocking plate 52 contacts the base 1 and the mounting plate 3, the locking ring 45 moves toward the mounting plate 3 to contact the protective block 54. The protective block 54 squeezes the elastic plate 53, causing the elastic plate 53 to shrink on the blocking plate 52, so that the movement of the locking ring 45 gradually stops. When the locking ring 45 moves away from the protective block 54, the elastic plate 53 stretches to push the protective block 54 to reset, and the blocking plate 52 is vibrated and transmitted to the protective tube 51, so that the movable frame 56 inside the protective tube 51 is vibrated to drive the purification tube 55 to rotate, so that the purification tube 55 purifies the gas inside the protective tube 51. Step six: Use the fixed plate 59 to support the support sleeve 58 inside the protective cylinder 51, so that the inner ring 57 on the support sleeve 58 is connected to the protective cylinder 51, and the partition frame 512 fixes the receiving plate 511 inside the support sleeve 58, so that the receiving plate 511 is set horizontally to receive the fallen impurities, and as the limiting plate 510 contacts the rotating purification cylinder 55 inside the support sleeve 58, the limiting plate 510 knocks when contacting the purification cylinder 55, and the purification cylinder 55 is restricted by the limiting plate 510 to rotate in the opposite direction.
