Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a mold forming device for producing injection molding barrels. Background Art

[0002] Injection molding barrels are made of plastic materials such as polyethylene and polypropylene through blow molding or injection molding, and the participation of injection molding machines is often required in their production process.

[0003] Injection molding machines are usually composed of an injection system, a clamping system, a hydraulic transmission system, an electrical control system, a lubrication system, a heating and cooling system, etc. The clamping system is used to control the opening and closing of the mold, thereby shaping the molten plastic injected into the mold cavity.

[0004] For example, in the patent document with patent publication number CN218477041U, a mold forming device for injection barrel production is disclosed, which includes a base, a support cylinder, an outer mold, an inner mold and a cylinder cover, the support cylinder is fixedly arranged on the top of the base, the outer mold is fixedly arranged on the top of the support cylinder, the inner mold is located inside the outer mold, and an injection cavity is formed between the inner mold and the outer mold, the cylinder cover is located on the top of the outer mold, and the bottom of the cylinder cover is fixedly connected to the top of the inner mold, an L-shaped support plate is fixedly arranged on one side of the top of the support cylinder, a cylinder is fixedly arranged on the top of the L-shaped support plate, the end of the piston rod of the cylinder is fixedly connected to the cylinder cover, and a feeding pipe is fixedly arranged on one side of the top of the cylinder cover; a motor is fixedly arranged on the top of the base, a laterally arranged swing rod is fixedly arranged on the end of the output shaft of the motor, a cam is fixedly arranged on the end of the swing rod, and a knocking rod is vertically rotated on the inner walls of both sides of the support cylinder, the lower end of the knocking rod can be arranged in contact with the cam, and a knocking head is fixedly arranged on the upper end of the knocking rod.

[0005] According to the prior art literature, the molding device drives the cam to rotate continuously through the motor, so that the cam repeatedly presses against the lower end of the knocking rod, and then the upper end of the knocking rod drives the knocking head to swing together, so that the bubbles in the injection cavity are discharged by the knocking of the knocking head on the outer mold. However, in order to ensure a good knocking effect, the motor needs to drive the cam to rotate at high speed, so as to achieve high-speed swinging of the knocking rod and the knocking head. However, in this process, the cam frequently squeezes and collides with the lower end of the knocking rod at high speed, which not only generates a large impact force, thereby causing certain damage to the connection structure of the device, but also after long-term use, the cam surface wears and causes increased friction, which is very likely to cause the cam and the knocking rod to get stuck, affecting the normal use of the device.

[0026] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model.

[0028] The positions of the cylinders 3 and the outer mold 4 are fixedly set. Driven by the telescopic rods of the cylinders 3, the inner mold 2 can enter and exit the inner cavity of the outer mold 4. When the circumferential side of the cover plate 1 is pressed against the annular top of the outer mold 4, the cylinder 3 stops working, and an injection cavity 5 is formed between the inner mold 2 and the outer mold 4. Then, the molten plastic is injected into the injection cavity 5 through the external injection molding system equipment, and the motor 6 is turned on during the cooling and molding process to drive the transmission gear set to work. At the same time, the vibration mechanism on both sides is driven by the transmission gear set to synchronously perform corresponding actions, thereby vibrating the molten plastic in the injection cavity 5, thereby effectively discharging the bubbles in the molten injection liquid and ensuring the quality of the molded product. After the molten plastic in the injection cavity 5 is formed, the cylinder 3 works again and drives the cover plate 1 and the inner mold 2 to move up, so as to facilitate the removal of the molded injection barrel.

[0029] In any of the above schemes, it is preferred that the transmission gear set includes a driving gear 7, the motor shaft of the motor 6 is coaxially fixedly connected to the first rotating shaft 8 through a coupling, the driving gear 7 is coaxially fixedly sleeved on the first rotating shaft 8, and driven gears 10 are respectively meshed and connected on the left and right sides of the driving gear 7, and a second rotating shaft 9 is fixedly inserted in the middle of each driven gear 10, and the upper end of each second rotating shaft 9 is respectively fixedly connected to the lower end of the vibration mechanism at the corresponding position.

[0030] The motor 6 works to drive the first rotating shaft 8 to rotate around its axial direction, and further drives the driving gear 7 to rotate around its axial direction. Through the meshing connection between the driving gear 7 and the driven gear 10, the two driven gears 10 rotate synchronously, and then drive their respective second rotating shafts 9 to rotate. Through the rotation of the second rotating shaft 9, the lower end of the vibration mechanism performs a corresponding action, so that the vibration mechanism finally realizes the vibration effect on the outer mold 4.

[0031] In any of the above schemes, it is preferred that the vibration mechanism includes a rotating disk 11, the bottom of the rotating disk 11 is coaxially fixedly connected to the upper end of the second rotating shaft 9 at the corresponding position, and a first positioning column 12 is fixedly connected to one side of the top of the rotating disk 11, and also includes a horizontally arranged connecting rod 13, both ends of the connecting rod 13 are integrally formed with annular sleeve portions, one end of the connecting rod 13 is movably sleeved on the first positioning column 12, and also includes a sliding displacement member, a second positioning column 14 is fixedly provided at the bottom at the corresponding position of the sliding displacement member, the other end of the connecting rod 13 is movably sleeved on the second positioning column 14, and a vibrator is fixedly provided at the top at the corresponding position of the sliding displacement member, and the vibrator is used to vibrate the vertical outer wall of the outer mold 4.

[0032] When the second rotating shaft 9 rotates, it drives the rotating disk 11 to rotate synchronously, thereby causing the first positioning column 12 to rotate eccentrically around the axial direction of the rotating disk 11. At the same time, through the movable connection between the first positioning column 12 and the corresponding end of the connecting rod 13, the end of the connecting rod 13 finally rotates around the axial direction of the rotating disk 11.

[0033] Since the connecting rod 13 is a rigid connecting member with a fixed length, when one end of the connecting rod 13 is displaced, the position of the other end of the connecting rod 13 will also be moved. Therefore, the utility model sets the other end of the connecting rod 13 on the sliding part of the sliding displacement member through the second positioning column 14. Under the guiding action of the sliding displacement member, when the corresponding end of the connecting rod 13 rotates eccentrically with the first positioning column 12, the other end of the connecting rod 13 drives the sliding part of the sliding displacement member to reciprocate in the horizontal direction, and further drives the vibrating member to reciprocate synchronously, thereby finally achieving the vibration effect of the vibrating member on the outer wall of the outer mold 4.

[0034] In any of the above schemes, it is preferred that the sliding displacement member includes a first mounting plate 15 fixedly arranged in the vertical direction, two mounting strips 16 are arranged at intervals along the width direction at the upper end of the first mounting plate 15, and the two mounting strips 16 are arranged in the horizontal direction. Linear guide rails 17 are fixedly connected to the inner wall surfaces of the two mounting strips 16 along their length directions, and a slider 18 is provided in the space between the two linear guide rails 17. The two side portions of the slider 18 are respectively slidably matched with the linear guide rails 17 at corresponding positions, the second positioning column 14 is fixedly connected to the bottom of the slider 18, and the vibrator is fixedly arranged on the top of the slider 18.

[0035] Under the cooperative connection and limiting effect of the two linear guides 17, the slider 18 can and can only perform translational movement along the length direction of the linear guide 17. In this way, under the connection transmission of the connecting rod 13, the slider 18 can reciprocate between the two linear guides 17, thereby finally realizing the reciprocating movement of the vibrator.

[0036] In any of the above schemes, it is preferred that the vibrating member includes a vertically arranged second mounting plate 19, the lower end of the second mounting plate 19 is fixedly connected to the top of the slider 18, and a plurality of mounting rods 20 are fixedly connected from top to bottom on the inner plate surface of the second mounting plate 19 at intervals, and a rubber vibration block 21 is fixedly connected to the inner end of each mounting rod 20, and each rubber vibration block 21 is used to knock on the corresponding position of the circumferential outer wall of the outer mold 4.

[0037] The slider 18 reciprocates in the horizontal direction, thereby driving the second mounting plate 19 to reciprocate in the horizontal direction, and further driving each mounting rod 20 and its corresponding rubber vibration block 21 to reciprocate in the horizontal direction, so that each rubber vibration block 21 continuously strikes the outer wall of the outer mold 4, and finally achieves a vibration effect on the molten plastic in the injection cavity 5.

[0038] The rubber vibration block 21 is made of rubber, which can reduce the impact on the outer mold 4 while achieving the knocking effect, thereby avoiding unnecessary damage to the outer mold 4.

[0039] In any of the above schemes, it is preferred that a third mounting plate 27 is horizontally fixedly connected to the lower end of the first mounting plate 15, a plurality of legs 29 are welded to the bottom of the third mounting plate 27, and the lower end of the second rotating shaft 9 is movably inserted into the rotating hole at the corresponding position of the third mounting plate 27.

[0040] A bearing is fixedly installed in the mounting hole at the corresponding position of the third mounting plate 27, and the second rotating shaft 9 is fixedly inserted in the shaft hole of the bearing. Through the welding and fixing of the first mounting plate 15, the third mounting plate 27 and the support leg 29, the transmission gear set and the vibration mechanism can be better supported and fixed.

[0041] In any of the above schemes, it is preferred that a first injection molding groove 22 is opened in the middle position of the upper part of the cover plate 1, and the upper end of the first injection molding groove 22 is connected to the outside, and second injection molding grooves 23 are opened on the left and right sides of the lower part of the cover plate 1 respectively, and the inner ends of the two second injection molding grooves 23 are inclined upward compared with the outer ends thereof. At the same time, the inner ends of the two second injection molding grooves 23 are connected to the lower end of the first injection molding groove 22, and the outer ends of the two second injection molding grooves 23 are connected to the injection cavity 5.

[0042] During the injection molding process, the nozzle of the external injection molding system equipment is placed close to the upper end of the first injection molding groove 22 , so that the molten injection liquid is squeezed into the interior thereof, and then enters the injection molding cavity 5 under the guidance of the second injection molding groove 23 .

[0043] When the rubber vibration block 21 vibrates the outer wall of the outer mold 4 , bubbles in the molten injection liquid are discharged from the injection cavity 5 , pass through the second injection groove 23 , and finally escape through the first injection groove 22 .

[0044] In order to facilitate the entry of molten injection liquid and the escape of bubbles, the second injection groove 23 is arranged at an angle.

[0045] In any of the above schemes, it is preferred that the upper end of each of the cylinders 3 is fixedly connected to a top plate 24, one end of the top plate 24 is fixedly connected to a support plate 25, the lower end of the support plate 25 is fixedly set on the ground, and a bracket 26 is fixedly connected at a corresponding position of the middle section of the support plate 25, and the outer end of the bracket 26 is fixedly installed on the outer wall of the outer mold 4.

[0046] The cylinder 3 and the outer mold 4 are supported and fixed by the fixed connection of the top plate 24, the support plate 25 and the bracket 26.

[0047] Specific working principle:

[0048] First, the cover plate 1 is controlled to move vertically downward by the cylinder 3, thereby driving the inner mold 2 to be inserted into the outer mold 4, and finally the cover plate 1 is tightly pressed against the top of the outer mold 4. Then the nozzle of the external injection molding system equipment is close to the first injection molding groove 22, so as to squeeze the molten injection liquid into the injection molding cavity 5. After the squeezing is completed, the motor 6 is turned on to drive the driving gear 7 to rotate, and at the same time, through the gear meshing relationship, the driven gear 10 and the corresponding rotating disk 11 are further driven to rotate synchronously. Then, under the coordinated transmission between the first positioning column 12, the connecting rod 13 and the second positioning column 14, the driving slider 18 is driven to reciprocate along the length direction of the linear guide 17, thereby driving the second mounting plate 19 to reciprocate in the horizontal direction, and finally realizing the vibration effect of each rubber vibration block 21 on the outer mold 4. Under the continuous vibration of the rubber vibration block 21, the bubbles in the molten injection liquid to be molded in the injection molding cavity 5 continuously escape through the first injection molding groove 22, thereby ensuring its good quality after molding. After the molten injection molding is completed, the cylinder 3 is operated again to drive the cover plate 1 and the inner mold 2 to move upward, so as to take out the molded injection molding barrel.
