Description

Technical Field

[0001] The invention relates to the technical field of residual material removal equipment for injection molds, in particular to a gate removal device for an injection mold of automobile parts. Background Art

[0002] The injection mold is equipped with a gate, which is also called a feed port. It is a narrow passage between the runner and the cavity. During the injection molding process, the gate is often blocked. Usually, the cause of gate blockage is the low-temperature condensation of the plastic melt in the gate. If the gate is blocked and not cleared in time, the molding quality of the injection mold will be affected. Therefore, it is generally necessary to clear the residual blockage inside the gate in time, which will use a gate clearing and clearing device.

[0003] An injection mold residual material cleaning device in the form of impact knocking and unblocking has a knocking and hammering component that is connected to the pouring channel of the gate and penetrates the unblocking structure, such as a poking rod, etc. When the residual material is impact-peeled off, it will generate relative friction resistance with the residual material attached to the inner wall of the pouring channel that has not been completely cleaned. The friction resistance is added to the poking rod, which will hinder the sliding and lifting of the poking rod and the knocking and hammering components. However, most of the existing cleaning devices lack an auxiliary mechanism that can implement force extraction on the poking rod, which makes the knocking and hammering components more troublesome and laborious during the sliding and lifting operation, which will indirectly reduce the up and down impact and unblocking efficiency of the device. Summary of the invention

[0004] In view of this, the present invention provides a gate cleaning device for an injection mold of an automobile part, so as to solve the problem that most cleaning devices lack an auxiliary mechanism that can implement force extraction on the poking rod, which makes the striking and hammering parts more troublesome and laborious during the sliding and lifting operations, indirectly reducing the efficiency of the device's up and down impact clearing.

[0005] The technical solution proposed by the present invention is: a gate cleaning device for an automobile parts injection mold, specifically comprising a T-shaped retainer and an injection mold, wherein a gate is inserted and installed at the top end of the injection mold;

[0006] A hammer block is mounted on the vertical support part of the T-shaped retainer through the push of the first spring to slide straight up and down; two force-bearing plates that are supported front and back are symmetrically slidably installed on the top cross support part of the T-shaped retainer along the length direction; two connecting rods are symmetrically rotatably connected to the hammer block, and the head ends of the two connecting rods are rotatably connected to the two force-bearing plates; a poking rod is welded at the bottom of the hammer block, and the poking rod slides downward to be plugged into the central pouring hole on the gate;

[0007] A driving assembly is rotatably installed at the middle position of the top end of the T-shaped retainer, and the driving assembly as a whole is composed of a strip driving plate and a rotating circle welded to the middle position of the strip driving plate. The strip driving plate rotates and contacts with two force-bearing plates to drive the hammer block and the poking rod to slide up and down to impact and peel off the residual material inside the gate. A circle of teeth is arranged around the circumferential inner wall of the rotating circle; a Z-shaped rocker is rotatably installed at the middle position of the top end of the T-shaped retainer, and the part of the Z-shaped rocker located on the inner side of the rotating circle is provided with a driving gear, which is rotatably connected to the Z-shaped rocker shaft through an internal ratchet mechanism, and the driving gear is meshed with a circle of teeth inside the rotating circle for transmission; a semicircular track ring is welded on the strip driving plate, and the semicircular track ring is connected to the The driving gear remains concentric, and an arc-shaped protective sleeve is installed on the semicircular track ring through a second spring push-pull sliding sleeve. The bottom end of the vertical support part of the Z-shaped rocker arm located on the outside of the rotating circle is welded and fixed to the arc-shaped protective sleeve; under the power transmission of the second spring, the Z-shaped rocker arm drives the driving component to rotate, and controls the hammer block to slide up and lift to accumulate force; the present invention only needs a simple action of continuously shaking the driving component to drive the hammer block to intermittently slide up and down to impact and clear the blockage. Compared with the traditional clearing device that uses external hammers and other tools to knock, poke and clear the poking rod, it can save the frequent force of swinging the hammer and the large-scale knocking action, and solves the problem that the traditional clearing device cannot be used in the cramped installation space of the injection mold and the operation is laborious and inconvenient.

[0008] The elastic force of the second spring is F2, the elastic force of the first springs at two locations is 2F1, the gravity of the hammer block is G, F2>2F1+G, and the friction resistance exerted on the poking rod by the residual material that is not completely peeled off in the pouring hole of the gate is F3; the second spring is used to transmit the rocking driving force of the Z-shaped rocker to the strip driving plate. Under normal circumstances, through the power transmission of the second spring, the Z-shaped rocker and the arc-shaped sheath can rock and drive the driving component to provide the hammer block with an impact force for sliding up and down; F3+2F1+G=the total sliding resistance applied to the hammer block. When F3+2F1+G>F2, the second spring is compressed by the arc-shaped sheath. The Z-shaped rocker can drive the driving gear and the rotating circle to move relative to each other, and mesh with the driving circle and the driving component to perform a small and slow rocking motion. The diameter of the driving gear is much smaller than the diameter of the rotating circle, which has the labor-saving effect of increasing torque and reducing speed. Through this effect, the torsional driving force applied by the Z-shaped rocker to the driving component and the extraction driving force on the hammer block can be effectively amplified, and the friction resistance applied by the residual material that is not completely stripped in the gate to the poking rod can be relatively easily resisted. It is relatively easy to implement upward sliding extraction of the hammer block, solving the problem that the sliding and lifting operation of the hammering component in the prior art is relatively troublesome and laborious, and the clearing and use are low;

[0009] When the friction resistance on the poking rod is offset or eliminated, the second spring can automatically push and drive the arc-shaped sleeve to slide back and reset, and restore the Z-shaped rocker to the use state of synchronously driving the drive component to swing and drive significantly, and then the force-added drive function realized by the second spring, the active gear and the rotating circle can be automatically triggered and released by relying on the friction resistance applied to the poking rod. Firstly, it can solve the trouble of additional manual operation to trigger and release the force-added drive function during use; secondly, it can make the Z-shaped rocker promptly restore to the fast impact drive state on the hammer block after the friction resistance is offset or eliminated, thereby solving the problem of excessive interference of the force-added drive function limiting the fast impact drive function.

[0010] The invention provides a gate cleaning device for an automobile parts injection mold, which has the following beneficial effects:

[0011] When the present invention is in use, only the simple action of continuously shaking the driving component is needed to drive the hammer block to intermittently slide back and forth up and down to impact and clear the blockage. Compared with the traditional clearing device that uses external hammers and other tools to knock, poke and clear the poking rod, the present invention can save the frequent and forceful swinging of the hammer and the large-scale knocking action. It is suitable for use in the cramped installation space of the injection mold and is labor-saving and convenient to operate.

[0012] In addition, when F3+2F1+G>F2, the second spring is compressed by the arc-shaped sleeve. At this time, the Z-shaped rocker can drive the active gear and the rotating circle to move relative to each other, and mesh with the driving circle and the driving component to perform a small and slow rocking motion. The diameter of the active gear is much smaller than the diameter of the rotating circle, which has the labor-saving effect of increasing torque and reducing speed. Through this effect, the torsional driving force applied by the Z-shaped rocker on the driving component and the extraction driving force on the hammer block can be effectively amplified, and it can easily counteract the additional friction resistance applied to the poking rod by the residual material that has not been completely stripped in the gate, and it is relatively easy to implement upward sliding extraction of the hammer block. Compared with the existing technology, the upward sliding lifting operation of the striking and hammering components is more convenient and labor-saving, which helps to indirectly improve the overall impact and clearing efficiency of the device.

[0013] In addition, the force-added driving function realized by the second spring, the active gear and the rotating circle can be automatically triggered and released by relying on the friction resistance applied to the poking rod. First, it can save the trouble of additional manual triggering and releasing during use. Second, after the friction resistance is offset or eliminated, the Z-shaped rocker can be promptly restored to the fast impact driving state of the hammer block, avoiding excessive interference and restriction of the fast impact driving function by the force-added driving function, so that the driving component can maximize its original fast impact driving function under the premise of having the force-added driving function, and has better practicality.

[0014] In addition, the locking bolt can be inserted into the positioning circle to keep the drive assembly in a retracted state where the left and right supports are approximately overlapped with the horizontal cross bar, and the poking rod in an upward sliding retracted state, to prevent the drive assembly from protruding significantly from the front and rear sides of the horizontal cross bar for a long time, and the poking rod from sliding down and protruding for a long time, occupying too much support space, making it easier to carry, transfer and store.

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0032] Please refer to Figures 1 to 8 ;

[0033] For the convenience of description, the length direction of the T-shaped retainer 1 is marked as the left-right direction, and the two sides of the two force-bearing plates 102 that are relatively supported are marked as the front-back direction; Embodiment 1:

[0034] The present invention provides a gate cleaning device for an automobile parts injection mold, comprising a T-shaped retainer 1 and an injection mold 2, wherein a gate 201 is inserted and installed at the top end of the injection mold 2;

[0035] Among them, the vertical support part of the T-shaped retainer 1 is pushed by the first spring 107 to slide straightly up and down, and a hammer block 3 is installed on the top cross support part of the T-shaped retainer 1 to slide symmetrically left and right. Two front and rear support force plates 102 are installed; the hammer block 3 is symmetrically connected to the rotation of two connecting rods 302, and the head ends of the two connecting rods 302 are rotationally connected to the two force plates 102; a poking rod 301 is welded at the bottom of the hammer block 3, and the poking rod 301 slides downward and is plugged into the central pouring hole on the gate 201. When in an idle state, the poking rod 301 is in a sliding and protruding use state (refer to Figure 1 ), when in use, the poking rod 301 is pushed back by the residual material in the pouring hole and slides upward to the top opening position of the pouring hole (refer to Figure 3 ), two force plates 102, two connecting rods 302 and hammer blocks 3 are connected together to form two crank slider mechanisms, through which the two force plates 102 that slide away from each other can push and drive the upper hammer block 3 to slide upward to lift and store force, and the hammer block 3 can compress the two first springs 107 to further store force when sliding upward to lift;

[0036] The driving assembly 4 is rotatably installed at the middle position of the top of the T-shaped retainer 1. The driving assembly 4 is composed of a strip driving plate and a rotating circle 401 welded to the middle position of the strip driving plate. The strip driving plate rotates and contacts with the two force-bearing plates 102. Through the strip driving plate, the driving assembly 4 can be rotated to push and drive the two force-bearing plates 102 to slide away from each other, and control the hammer block 3 to slide upward and lift. When the strip driving plate is rotated and separated from the two force-bearing plates 102, the hammer block 3 loses the pushing and holding force of the strip driving plate, and relies on its own weight to drive The poking rod 301 is made to slide downward to impact and peel off the residual material inside the gate 201. In this way, only a simple action of continuously shaking the driving component 4 can drive the hammer block 3 to intermittently slide up and down to impact and clear the blockage. Compared with the traditional clearing device that uses an external hammer or other tools to knock, poke and dredge the poking rod 301, it can save the frequent and large-scale knocking actions of swinging the hammer, which is suitable for use in the cramped installation space of the injection mold 2, and is labor-saving and convenient to operate; when the hammer block 3 slides downward to impact, the two first springs 107 can The compressed and accumulated rebound thrust is applied to the hammer block 3, increasing the downward impact force of the hammer block 3, improving the impact stripping effect of the poking rod 301 on the residual material, so that the hammer block 3 and the poking rod 301 can penetrate the pouring hole of the gate 201 to complete the blockage removal under fewer reciprocating impact times, which is helpful to improve the blockage removal efficiency of the device; a circle of teeth is arranged around the inner wall of the circumference of the rotating circle 401; a Z-shaped rocker 104 is rotatably installed through the middle position of the top of the T-shaped retainer 1, and the Z-shaped rocker 104 is located at the inner part of the rotating circle 401 The sub-assembly is provided with a driving gear 105, which is axially connected to the Z-shaped rocker 104 through an internal ratchet mechanism for rotation, and the driving gear 105 is meshed with a circle of teeth inside the rotating circle 401 for transmission; a semicircular track ring 402 is welded on the strip-shaped driving plate, and the semicircular track ring 402 is kept concentric with the driving gear 105, and an arc-shaped sheath 403 is installed on the semicircular track ring 402 through a second spring 4021 to push and slide, and the bottom end of the vertical support part of the Z-shaped rocker 104 located outside the rotating circle 401 is welded and fixed to the arc-shaped sheath 403;

[0037] The elastic force of the second spring 4021 is F2, the elastic force of the two first springs 107 is 2F1, the gravity of the hammer block 3 is G, F2>2F1+G, and the friction resistance exerted by the residual material that is not completely peeled off in the pouring hole of the gate 201 on the poking rod 301 is F3; the second spring 4021 is used to transmit the swing driving force of the Z-shaped rocker 104 to the strip driving plate. Under normal circumstances, the Z-shaped rocker 104 and the arc-shaped sheath 403 can be driven by swinging through the power transmission of the second spring 4021. The driving assembly 4 provides the hammer block 3 with an impact force for sliding up and down; F3+2F1+G=the total sliding resistance applied to the hammer block 3. When F3+2F1+G<F2, the second spring 4021 is sufficient to resist the total sliding resistance applied to the hammer block 3 and maintain the extended and uncompressed or slightly compressed state. At this time, the Z-shaped rocker 104, the driving gear 105 and the rotating circle 401 remain relatively still, and the Z-shaped rocker 104 can directly rely on the second spring in the extended state to move upward. The spring 4021 drives the driving assembly 4 to perform synchronous large-scale swinging and driving, and controls the hammer block 3 to perform impact sliding and clearing at a faster speed; when F3+2F1+G>F2, the second spring 4021 is compressed by the arc-shaped sheath 403, and at this time, the Z-shaped rocker 104 can drive the driving gear 105 to move relative to the rotating circle 401, and mesh with the rotating circle 401 and the driving assembly 4 to perform a small and slow swinging movement. The diameter of the driving gear 105 is much smaller than the diameter of the rotating circle 401, which has the effect of increasing torque. The labor-saving effect of deceleration can effectively amplify the torsional driving force applied by the Z-shaped rocker 104 to the driving component 4 and the extraction driving force on the hammer block 3, and can easily resist the additional friction resistance applied by the residual material that is not completely stripped in the gate 201 to the poking rod 301, and it is relatively easy to implement upward sliding extraction on the hammer block 3. Compared with the prior art, the upward sliding lifting operation of the hammering component is more convenient and labor-saving, which helps to indirectly improve the overall impact and clearing efficiency of the device;

[0038] When the friction resistance on the poking rod 301 is offset or eliminated, the second spring 4021 can automatically push and drive the arc-shaped sheath 403 to slide back and reset, and restore the Z-shaped rocker 104 to the use state of synchronously driving the driving component 4 to swing and drive significantly, and then the force-added driving function realized by the second spring 4021, the active gear 105 and the rotating circle 401 can be automatically triggered and released by relying on the friction resistance applied to the poking rod 301. First, it can save the trouble of additional manual triggering and releasing during use. Second, after the friction resistance is offset or eliminated, the Z-shaped rocker 104 can be promptly restored to the fast impact driving state for the hammer block 3, avoiding excessive interference and restriction of the fast impact driving function by the force-added driving function, so that the driving component 4 can maximize its original fast impact driving function under the premise of having the force-added driving function, and has better practicality.

[0039] The internal ratchet mechanism can ensure that the Z-shaped rocker 104 drives the driving gear 105 in one direction, so that the driving gear 105 and the rotating circle 401 are decoupled and idle when the arc-shaped sleeve 403 slides back and resets to release the boost drive function, avoiding the two-way meshing and continuous transmission between the rotating circle 401 and the driving gear 105, blocking and restricting the return of the arc-shaped sleeve 403, and hindering the automatic release of the boost drive function.

[0040] Preferably,

[0041] The T-shaped retainer 1 as a whole is composed of a top horizontal crossbar and two vertical support rods symmetrically welded at the middle bottom position of the horizontal crossbar. A first spring 107 is sleeved on the two vertical support rods, and the hammer block 3 is slidably matched with the two vertical support rods.

[0042] Preferably,

[0043] The bottom of the two vertical support rods is welded with a baffle 106, the hammer block 3 slides down and abuts against the baffle 106, and the poking rod 301 penetrates and slides with the baffle 106;

[0044] A convex block 1061 is welded to the bottom of the baffle 106, and a concave hole is provided at the top of the gate 201. When in use, the baffle 106 slides down and abuts against the top surface of the gate 201. The convex block 1061 and the concave hole are plugged and matched to maintain the connection stability between the baffle 106 and the T-shaped retainer 1 and the gate 201.

[0045] Two longitudinal handles perpendicular to each other are welded at the left and right ends of the horizontal crossbar. When in use, the device is positioned by grasping the longitudinal handles.

[0046] Preferably,

[0047] A mounting plate 103 with a T-shaped cross section is welded in the middle of the horizontal crossbar, the rotating circle 401 is rotatably matched with the mounting plate 103, and the vertical support part of the Z-shaped rocker 104 located inside the rotating circle 401 is penetrated and rotatably matched with the mounting plate 103;

[0048] An annular groove is provided at the bottom of the inner wall of the rotating circle 401 , and the annular groove is rotatably matched with the top portion of the mounting plate 103 .

[0049] Preferably,

[0050] A sliding sleeve 1021 is welded to the bottom of the two force-bearing plates 102 . The two sliding sleeves 1021 are slidably matched with the horizontal cross bar, and the head ends of the two connecting rods 302 are rotatably connected to the two sliding sleeves 1021 .

[0051] On the basis of the first embodiment, the second embodiment, as Figures 7 and 8 As shown:

[0052] A positioning ear block 4011 is welded on the circumferential outer wall of the rotating circle 401; a locking bolt 101 is screwed and installed through the middle part of the horizontal cross bar, and the top protruding part of the locking bolt 101 is inserted and matched with the positioning ear block 4011. The locking bolt 101 can be inserted into the positioning rotating circle 401, so that the driving component 4 is kept in a contracted state where the left and right supports are approximately overlapped with the horizontal cross bar, and the poking rod 301 is kept in an upward sliding contracted state (refer to Figure 7 ), to prevent the driving assembly 4 from protruding significantly from the front and rear sides of the horizontal cross bar for a long time, and the poking rod 301 from sliding down and protruding for a long time, occupying too much support space, so as to facilitate carrying, transfer and storage.

[0053] Working principle: When in use, the poking rod 301 slides downward and plugs into the central pouring hole on the gate 201, and the baffle plate 106 slides down and contacts the top surface of the gate 201. The protrusion 1061 plugs into the concave hole to maintain the connection stability between the baffle plate 106 and the T-shaped retainer 1 and the gate 201. The device is positioned by holding the longitudinal handle;

[0054] When in use, the poking rod 301 is pushed back by the residual material in the pouring hole to slide upward and be placed at the top opening position of the pouring hole. The two force plates 102, the two connecting rods 302 and the hammer block 3 are connected together to form two crank slider mechanisms. Through these two mechanisms, the two force plates 102 that slide away from each other to the left and right can push and drive the upper hammer block 3 to slide upward and lift to accumulate force. When the hammer block 3 slides upward and lifts, the two first springs 107 can be compressed to further accumulate force. Through the strip driving plate, the driving component 4 can rotate to push and drive the two force plates 102 to slide away from each other to the left and right, thereby controlling the hammer block 3 to slide upward and lift. When the strip driving plate and the two force-bearing plates 102 rotate and disengage, the hammer block 3 loses the pushing and holding force of the strip driving plate, and relies on its own weight to drive the poking rod 301 to slide downward to impact and strip the residual material from the inside of the gate 201. In this way, only a simple action of continuously shaking the driving component 4 is needed to drive the hammer block 3 to intermittently slide up and down to impact and clear the blockage. When the hammer block 3 slides downward to impact, the two first springs 107 can apply their compressed and accumulated rebound pushing force to the hammer block 3, thereby increasing the downward impact force of the hammer block 3 and improving the impact and stripping effect of the poking rod 301 on the residual material.

[0055] The elastic force of the second spring 4021 is F2, the elastic force of the two first springs 107 is 2F1, the gravity of the hammer block 3 is G, F2>2F1+G, and the friction resistance exerted on the poking rod 301 by the residual material that is not completely peeled off in the pouring hole of the gate 201 is F3; the second spring 4021 is used to transmit the rocking driving force of the Z-shaped rocker 104 to the strip driving plate. Under normal conditions, the Z-shaped rocker 104 is driven by the power transmission of the second spring 4021. The arc-shaped sheath 403 can be swung to drive the driving assembly 4 to provide the hammer block 3 with an impact force to slide up and down; F3+2F1+G=the total sliding resistance applied to the hammer block 3. When F3+2F1+G<F2, the second spring 4021 is sufficient to resist the total sliding resistance applied to the hammer block 3 and maintain the stretched and uncompressed or slightly compressed state. At this time, the Z-shaped rocker 104, the driving gear 105 and the rotating circle 401 are relatively Keeping still, the Z-shaped rocker 104 can directly rely on the second spring 4021 in the extended state to implement synchronous and large-scale rocking drive on the driving component 4, and control the hammer block 3 to implement impact sliding and clearing at a faster speed; when F3+2F1+G>F2, the second spring 4021 is compressed by the arc-shaped sheath 403, and the Z-shaped rocker 104 can drive the active gear 105 and the rotating circle 401 to move relative to each other, and mesh the rotating circle 401 and the driving component 4 to perform a small and slow rocking movement. The diameter of the active gear 105 is much smaller than the diameter of the rotating circle 401, and has a labor-saving effect of increasing torque and reducing speed. Through this effect, the torsional driving force applied by the Z-shaped rocker 104 to the driving component 4 and the extraction driving force on the hammer block 3 can be effectively amplified, and the friction resistance of the residual material that is not completely stripped in the gate 201 on the poking rod 301 can be relatively easily resisted, and the hammer block 3 can be relatively easily implemented to slide up and extract;

[0056] After the friction resistance of the poking rod 301 is offset or eliminated, the second spring 4021 can automatically push and drive the arc-shaped sheath 403 to slide back and reset, and restore the Z-shaped rocker 104 to the state of synchronously driving the driving assembly 4 to swing and drive. The internal ratchet mechanism can ensure that the Z-shaped rocker 104 drives the driving gear 105 in one direction, so that the driving gear 105 and the rotating circle 401 are decoupled and idle when the arc-shaped sheath 403 slides back and resets to release the booster drive function, avoiding the two-way meshing and continuous transmission between the rotating circle 401 and the driving gear 105, blocking and restricting the arc-shaped sheath 403 from returning to its original position, and hindering the automatic release of the booster drive function.

[0057] When idle, the locking bolt 101 is used to insert the positioning circle 401, so that the drive assembly 4 is kept in a retracted state where the left and right supports are approximately overlapped with the horizontal crossbar, and the poking rod 301 is kept in an upward sliding retracted state (refer to Figure 7 ).
