Description

Technical Field

[0001] The invention relates to the technical field of plastic processing, in particular to an injection molding device for a shock-absorbing buffer block. Background Art

[0002] The injection molding device of the shock-absorbing buffer block is a professional equipment used to manufacture shock-absorbing buffer blocks. It processes plastic raw materials into shock-absorbing buffer blocks with specific shapes and properties through injection molding process. The plastic raw materials are first added to the barrel, heated to a molten state by a heating device, and the molten plastic is injected into the closed mold cavity at high pressure and high speed. In the mold, the molten plastic fills the cavity under pressure and gradually cools and solidifies under the action of the cooling system, and finally forms a shock-absorbing buffer block with the same shape as the mold cavity. After molding, the clamping mechanism opens the mold, and the ejection mechanism pushes the shock-absorbing buffer block out of the mold to complete an injection molding cycle. When adding materials, if the feeding speed is too fast, the raw materials will accumulate in the barrel and cannot be transported and melted forward in time, resulting in blockage. The barrel blockage will force the injection molding process to be interrupted, and it will take time to clean the blocked barrel and troubleshoot. This will not only cause delays in the production of the current batch of shock-absorbing buffer blocks, but may also affect the normal progress of subsequent production plans and reduce production efficiency.

[0033] There are four closing plates 201a, all of which are arranged in the discharge barrel 101. Teeth are arranged at one end of the closing plate 201a, which mesh with the gear ring 201b, and tooth grooves are arranged at the bottom of the gear ring 201b, which mesh with the gear 201c. When adding materials, the top of the closing plate 201a is a reserved bin, and the rotation of the gear 201c can drive the gear ring 201b to rotate, and the rotation of the gear ring 201b drives the closing plate 201a to rotate, so that the closing plate 201a can be opened. At this time, the raw materials in the discharge barrel 101 will fall to the bottom of the discharge barrel 101, and the cam 201f will rotate while the gear 201c rotates.

A sliding groove is provided in the wheel disc 301g, and the sliding wheel slides in the sliding groove. By adjusting the squeezing block 301a to different sides of the adjusting plate 301f, the adjusting plate 301f can squeeze the moving plate 301d to different degrees to move the moving plate 301d to different positions. When the moving plate 301d moves, it can drive the squeezing block 301a to move. When the squeezing block 301a moves, it can apply a squeezing force to the first spring 301c.

[0037] Example 2 Reference Figure 2~Figure 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, the unloading assembly 200 also includes a support member 202, which is arranged on the ring gear 201b. A positioning plate 202a is sleeved on the outer side of the ring gear 201b. The ring gear 201b and the positioning plate 202a are rotatably connected via a bearing. The closing plate 201a is rotatably connected to the positioning plate 202a via a rotating shaft. The gear 201c is rotatably connected to one side of the positioning plate 202a via a rotating shaft. A pulley 202b is fixed to one side of the gear 201c. A moving rope 202c is sleeved on the outer side of the pulley 202b. There are two pulleys 202b, and the other one is fixed to one side of the cam 201f.

[0039] The positioning plate 202a is fixed to the inner wall of the discharge barrel 101.

There are two pulleys 202b, both of which are plugged into one side of the discharge barrel 101. The pulley 202b is rotatably connected to the discharge barrel 101 through a rotating shaft. A sealing ring is provided on one side of the discharge barrel 101 to prevent leakage of raw materials. When the driving plate 202n is squeezed, the moving rope 202c can be driven to move. The movement of the moving rope 202c can simultaneously drive the two pulleys 202b to rotate. The rotation of the pulley 202b can simultaneously drive the gear 201c and the cam 201f to rotate.

[0040] Specifically, a movable wheel 202d is provided at one end of the moving bar 201e, and the movable wheel 202d is movably connected to one end of the moving bar 201e. A positioning plate 202e is sleeved on the outer side of the moving bar 201e. The moving bar 201e and the positioning plate 202e are movably connected. A second spring 202f is fixed at the bottom of the positioning plate 202e, and one end of the second spring 202f is fixed to the top of the movable wheel 202d.

[0041] When the cam 201f rotates, it can squeeze the movable wheel 202d, and the movable wheel 202d can drive the moving bar 201e to move. When the cam 201f reverses, the convex surface will separate from the movable wheel 202d. At this time, the moving bar 201e can return to its original position, so that the dredging column 201d can move back and forth. The positioning plate 202e is fixed to the inner wall of the discharge barrel 101. The positioning plate 202e can be set to support the moving bar 201e to prevent the moving bar 201e from shifting during movement.

When the cam 201f squeezes the movable wheel 202d, the movable wheel 202d can drive the support frame to move, and the movement of the support frame can apply a squeezing force to the second spring 202f. When the convex surface on the cam 201f separates from the movable wheel 202d, the movable bar 201e can return to its original position through the rebound force of the second spring 202f.

[0043] Specifically, a moving rod 202g is sleeved on the outer side of the moving rope 202c, a moving shell 202h is fixed to the bottom of the moving rod 202g, an inclined panel 202i is fixed in the moving shell 202h, an extrusion wheel 202j is arranged on one side of the inclined panel 202i, an extrusion bar 202k is fixed on one side of the extrusion wheel 202j, a pressure plate 202l is sleeved on the outer side of the extrusion bar 202k, a third spring 202m is fixed to one side of the pressure plate 202l, and a driving plate 202n is fixed to one end of the extrusion bar 202k.

The movement of the squeezing bar 202k drives the squeezing wheel 202j to move, and the squeezing wheel 202j moves on the inclined plate 202i, so that the inclined plate 202i drives the moving shell 202h to move, and the moving shell A return spring is fixed at the bottom of 202h, and the return spring is fixed to the inner wall of the supporting shell 302b. When the movable shell 202h moves, it can exert an extruding force on the return spring, and the movement of the movable shell 202h drives the movable rod 202g to move. At this time, the movement of the movable rod 202g can drive the movable rope 202c to move. When the extrusion on the driving plate 202n is released, the rebound force of the third spring 202m can drive the extrusion wheel 202j to return to its original position to release the extrusion on the inclined panel 202i, and then the rebound force of the return spring can drive the movable shell 202h to return to its original position.

[0045] Specifically, the extrusion assembly 300 also includes a driving member 302, which is arranged on the wheel disc 301g, a turntable 302a is fixed on one side of the wheel disc 301g, a support shell 302b is sleeved on the outer side of the turntable 302a, the turntable 302a and the support shell 302b are rotatably connected through a rotating shaft, a driving block 302c is fixed on one side of the turntable 302a, a ramp block 302d is arranged on one side of the driving block 302c, a connecting plate 302e is fixed on one side of the ramp block 302d, a connecting rod 302f is fixed on one side of the connecting plate 302e, a positioning sleeve 302g is sleeved on the outer side of the connecting rod 302f, the connecting rod 302f and the positioning sleeve 302g are movably connected, and the positioning sleeve 302g is fixed to the inner wall of the support shell 302b.

[0046] There are two inclined plane blocks 302d, both of which are fixed on one side of the connecting plate 302e. When the mold plate 103 moves, it can drive the connecting rod 302f to move. The positioning sleeve 302g is used to support the connecting rod 302f to prevent the connecting rod 302f from deviating. The movement of the connecting rod 302f drives the connecting plate 302e to move. The movement of the connecting plate 302e will drive the inclined plane block 302d to move.

At this time, the driving block 302c can drive the turntable 302a to rotate, and the rotation of the turntable 302a can drive the wheel 301g to rotate. The setting of the support shell 302b can support the turntable 302a to prevent the turntable 302a from deviating.

[0047] Specifically, the extrusion assembly 300 also includes a limit member 303, which is arranged on the support frame 301b. A limit block 303a is arranged below the support frame 301b.

When it is necessary to release the limiting of the extrusion block 301a, the support bar 303b is moved. The support bar 303b can apply an extrusion force to the fourth spring 303d when moving. At this time, the limiting block 303a is separated from the limiting groove to release the limiting of the extrusion block 301a. When the limiting block 303a is moved to the side of the next limiting groove, the rebound force of the fourth spring 303d can drive the limiting block 303a to engage with the limiting groove, thereby limiting the extrusion block 301a. The support bar 303b can be supported by the setting of the fixing sleeve 303c to prevent the support bar 303b from deviating.

[0049] Example 3 Reference Figure 1 to Figure 10 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0053] The setting of the pressing block 303h makes it easy for the user to move the movable plate 303e. When the movable plate 303e is moved, a squeezing force can be applied to the fifth spring 303i. When the pressing block 303h is released, the rebound force of the fifth spring 303i can drive the pressing block 303h to return to its original position.

[0054] Specifically, it also includes a main body component 100, which is arranged on the positioning plate 202a, including a lower barrel 101 and an injection molding machine 102.

[0055] The lower barrel 101 is a container for storing plastic raw materials, providing a continuous supply of raw materials for the injection molding process. The lower barrel 101 can accommodate a certain amount of plastic particles or powder to ensure that there is a sufficient supply of raw materials during the injection molding process to avoid interruption of production due to insufficient raw materials. The lower barrel 101 of the injection molding machine 102, under the action of the heating device, further heats the raw materials sent from the lower barrel 101 to a completely molten state, and stirs, compacts and plasticizes the molten raw materials through the rotation of the screw to make it a uniform melt with good fluidity and plasticity, ready for subsequent injection molding.

[0056] Specifically, the injection molding machine 102 is provided with a mold plate 103, and the mold plate 103 is fixed to one end of the connecting rod 302f.

[0057] The mold plate 103 is processed with a cavity that completely matches the shape of the shock-absorbing buffer block. It is the place where the shock-absorbing buffer block is finally formed. After the molten plastic is injected into the cavity, under the restriction of the mold, the plastic is filled, cooled and solidified according to the shape of the cavity, thereby forming a shock-absorbing buffer block product with a specific shape and dimensional accuracy.

[0058] When in use, first adjust the squeezing block 301a to the specified position, and press the pressing block 303h. At this time, the pressing block 303h can drive the movable plate 303e to move. When the movable plate 303e is moved, a squeezing force can be applied to the fifth spring 303i. The movement of the movable plate 303e can squeeze the movable block 303k. By squeezing the movable block 303k, the support bar 303b can be driven to move. When the support bar 303b moves, a squeezing force can be applied to the fourth spring 303d. At this time, the limiting block 303a is separated from the limiting groove to release the limiting of the squeezing block 301a. Then, the support frame 301b is moved. The support frame 301b drives the squeezing block 301a to move. By moving the squeezing block 301a to the specified adjustment plate 30 1f side, and then release the pressing block 303h, and the pressing block 303h is driven to return to its original position by the rebound force of the fifth spring 303i. At this time, the rebound force of the fourth spring 303d can drive the limiting block 303a to engage with the limiting groove, so as to limit the extrusion block 301a. At this time, when the extrusion block 301a is moved to the designated side of the adjustment plate 301f, the extrusion block 301a can be driven to move by the adjustment plate 301f to squeeze the movable plate 301d, and the extrusion block 301a is moved to the designated position. The extrusion block 301a can apply an extrusion force to the first spring 301c when moving. If the movable plate 301d is moved to separate from the adjustment plate 301f, the rebound force of the first spring 301c can make the extrusion block 301a return to its original position.

[0059] After the position adjustment of the extrusion block 301a is completed, the material can be added into the discharge barrel 101, and the injection molding machine 102 can be started at this time. The injection molding machine 102 drives the mold plate 103 to move, and the mold plate 103 can drive the connecting rod 302f to move when moving. The movement of the connecting rod 302f drives the connecting plate 302e to move, and the movement of the connecting plate 302e drives the inclined surface block 302d to move. The movement of the inclined surface block 302d can extrude the driving block 302c, and the driving block 302c can drive the turntable 302a to rotate, and the rotation of the turntable 302a can drive the wheel plate 301g to rotate, and the rotation of the wheel plate 301g drives the extrusion block 301a to rotate, and the extrusion block 301a is moved to the side of the driving plate 202n to extrude it, and the movement of the driving plate 202n The extrusion bar 202k can be driven to move, and when the extrusion bar 202k moves, the pressure plate 202l can be driven to move, and the movement of the pressure plate 202l can apply an extrusion force to the third spring 202m, and the movement of the extrusion bar 202k drives the extrusion wheel 202j to move, and the extrusion wheel 202j moves on the inclined panel 202i so that the inclined panel 202i can drive the moving shell 202h to move, and the moving shell 202h can apply an extrusion force to the return spring when moving, and the movement of the moving shell 202h drives the moving rod 202g to move, and at this time, the movement of the moving rod 202g can drive the moving rope 202c to move, and the movement of the moving rope 202c can simultaneously drive the two pulleys 202b to rotate, and the rotation of the pulley 202b can simultaneously drive the gear 201c and the cam 201f to rotate.

[0060] When the gear 201c rotates, it can drive the ring gear 201b to rotate, and the rotation of the ring gear 201b drives the closing plate 201a to rotate, so that the closing plate 201a can be opened to a specified size. At this time, the raw materials in the lower barrel 101 will fall to the bottom of the lower barrel 101, and then be transmitted to the injection molding machine 102 through the lower barrel 101. When the cam 201f rotates, it can squeeze the movable wheel 202d, and the movable wheel 202d can drive the moving bar 201e to move, and the movement of the moving bar 201e drives the dredging column 201d to move. By moving the dredging column 201d, the inside of the discharge barrel 101 can be dredged, so that the discharge can be smoother and more even. When the cam 201f squeezes the movable wheel 202d, the movable wheel 202d can drive the support frame to move. Through the movement of the support frame, an extrusion force can be applied to the second spring 202f. When the convex surface on the cam 201f is separated from the movable wheel 202d, the rebound force of the second spring 202f can make the movable bar 201e return to its original position, and the dredging column 201d can be moved back and forth in this reciprocating manner.
