Technical Field

[0001] The utility model relates to the technical field of injection molding molds, in particular to a one-mold multi-cavity injection molding mold. Background Art

[0002] Injection mold processing is to first add plastic into the mold, then the mold is continuously rotated along two vertical axes and heated. Under the action of gravity and heat energy, the plastic in the mold is gradually and evenly coated, melted and adhered to the entire surface of the mold cavity, forming into the required shape, and then cooled and shaped. Injection mold generally refers to injection molding, also known as injection molding, which is a molding method of injection and molding.

[0003] After injection molding, the molded model needs to be taken out of the current injection mold. However, the traditional injection mold is easy to damage the model during the taking out process, resulting in a decrease in the quality of the model. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a one-mold multi-cavity injection molding mold.

[0005] The utility model is achieved in this way:

[0006] The one-mold multi-cavity injection molding mold comprises a first mounting seat and a second mounting seat, the top four corners of the first mounting seat are connected with support rods, and the top ends of several of the support rods are interconnected with the bottom of the second mounting seat, a lower mold seat is installed at the top center of the first mounting seat, and a pair of mold cavities are provided inside the lower mold seat, and a discharge plate is slidably installed inside the pair of mold cavities, a mounting plate is installed at the bottom of the discharge plate inside the mold cavity, and a pair of fixed blocks are installed at the bottom of the discharge plate and the top of the mounting plate, a rotating shaft is inserted between the two pairs of fixed blocks, the outer sleeve of one of the rotating shafts is provided with a first adjusting rod, and one end of the first adjusting rod is hinged to the second adjusting rod, and one end of the second adjusting rod is hinged to the other rotating shaft, a discharge mechanism is provided on one side of the mounting plate, and the discharge mechanism includes a first adjusting rod, a fixed seat is installed on the top of the first mounting seat on both sides of the lower mold seat, a dust removal mechanism is provided on one side of the fixed seat, and the dust removal mechanism includes a suction cup.

[0007] Furthermore, a motor is installed on one side of the top of the first mounting seat, a rotating rod is inserted into one side of the inner part of a pair of the mold cavities, and the output end of the motor is transmission-connected to one of the rotating rods.

[0008] Furthermore, one end of the pair of rotating rods is sleeved with a driving bevel gear, and one end of the pair of rotating shafts passes through the fixed block and is sleeved with a driven bevel gear, and the driving bevel gear and the driven bevel gear are meshed with each other.

[0009] Furthermore, one end of the pair of rotating rods passes through the lower die base and is sleeved with a synchronous wheel, and a synchronous belt is meshed between the pair of synchronous wheels.

[0010] The beneficial effect of adopting the above further solution is that, by installing a synchronous wheel and a synchronous belt, a pair of rotating rods can be driven to rotate simultaneously, thereby driving the rotating shaft to rotate.

[0011] Furthermore, a pump is installed inside the first mounting seat, and a pair of dust collecting pipes are connected to both sides of the pump, and one end of the pair of dust collecting pipes passes through the fixing seat and is connected to a suction cup.

[0012] The beneficial effect of adopting the above further solution is that by installing a suction cup, impurities remaining on the discharge plate can be sucked out without the need for manual cleaning.

[0013] Furthermore, a cylinder is installed on the top of the second mounting seat, and the output end of the cylinder is connected to a piston rod, and the bottom end of the piston rod passes through the second mounting seat and is connected to a movable plate.

[0014] Furthermore, sliding rods are connected to both sides of the top of the lower mold base, and one end of a pair of the sliding rods passes through the movable plate and extends to the top.

[0015] The beneficial effect of adopting the above further solution is that, by installing the sliding rod, the movement of the movable plate can be supported and limited.

[0016] The beneficial effects of the utility model are as follows: the one-mold multi-cavity injection molding mold obtained by the utility model through the above design conveys the hot-melt raw material into the injection mold, and then starts the cylinder to drive the movable plate to move up and down, and at the same time, the movable plate moves on a pair of sliding rods to support the movement of the movable plate. When the upper mold base and the mold cavity are engaged with each other, the raw material is injection molded, and then the piston rod is shortened to make the movable plate drive the upper mold base to move, so that the upper mold base and the mold cavity are separated from each other. In order to protect the mold after molding, the motor is started to drive one of the rotating rods to rotate, and cooperate with the synchronous wheel and the synchronous belt to drive the pair of rotating rods to rotate simultaneously, so that the rotating rods The driving bevel gear is driven to rotate, which in turn drives the driven bevel gear to rotate. The driven bevel gear drives the rotating shaft to rotate. When the rotating shaft rotates, the angle of the first adjusting rod and the second adjusting rod are driven to adjust. When the angle of the first adjusting rod and the second adjusting rod becomes larger, the discharge plate is pushed to move upward, and the model on the discharge plate is pushed out of the mold cavity, which is convenient for taking the molded model without causing damage to the model. At the same time, the pump is started to generate negative pressure. A pair of dust collecting pipes cooperate with the suction cup to remove the debris remaining on the discharge plate. When the angle of the first adjusting rod and the second adjusting rod becomes smaller, the discharge plate is pulled downward to facilitate the subsequent injection molding of the model, thereby improving the convenience of use.

[0027] Embodiment 2 of the utility model of a one-mold multi-cavity injection molding die

[0028] For reference, specific examples Figure 1 and Figure 4A pump is installed inside the first mounting seat 1001, and a pair of dust collecting pipes 3002 are connected to both sides of the pump, one end of the pair of dust collecting pipes 3002 passes through the fixed seat 3001 and is connected to a suction cup 3003, a cylinder 1004 is installed on the top of the second mounting seat 1003, and a piston rod 1005 is connected to the output end of the cylinder 1004, the bottom end of the piston rod 1005 passes through the second mounting seat 1003 and is connected to a movable plate 1006, the lower die seat 2001 Slide bars 1007 are connected to both sides of the top, and one end of a pair of the slide bars 1007 passes through the movable plate 1006 and extends to the top.

By installing a suction cup 3003, impurities remaining on the discharge plate 2003 can be sucked out without manual cleaning. By installing the slide bars 1007, the movement of the movable plate 1006 can be supported and limited.

[0029] Specifically, the working principle of this type of one-mold multi-cavity injection molding mold is as follows: when in use, the hot-melt raw material is transported into the injection mold, and then the cylinder 1004 is started, so that the cylinder 1004 drives the movable plate 1006 to move up and down, and at the same time, the movable plate 1006 moves on a pair of slide bars 1007 to support the movement of the movable plate 1006.

In order to protect the mold after molding, the motor 2004 is started, so that the motor 2004 drives one of the rotating rods 2005 to rotate, and cooperates with the synchronous wheel 2012 and the synchronous belt 2013 to drive a pair of rotating rods 2005 to rotate simultaneously, so that the rotating rod 2005 drives the active bevel gear 2006 rotates, driving the driven bevel gear 2007 to rotate, and the driven bevel gear 2007 drives the rotating shaft 2009 to rotate. When the rotating shaft 2009 rotates, the angle of the first adjusting rod 2010 and the second adjusting rod 2011 is adjusted. When the angle of the first adjusting rod 2010 and the second adjusting rod 2011 becomes larger, the discharge plate 2003 is pushed to move upward in the mold cavity 2002, and the model on the discharge plate 2003 is pushed to the top of the mold cavity 2002, so that the molded model can be taken out without damaging the model. At the same time, the pump is started to generate negative pressure. A pair of dust collecting pipes 3002 cooperates with the suction cup 3003 to suck out the debris remaining on the discharge plate 2003. When the angle of the first adjusting rod 2010 and the second adjusting rod 2011 becomes smaller, the discharge plate 2003 is pulled to move downward, so that the model can be continued to be injected, thereby improving the convenience of use.

[0030] It should be noted that the specific model and specifications of the one-mold multi-cavity injection molding mold motor 2004 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0031] The power supply and principle of the one-mold-multi-cavity injection molding mold motor 2004 are clear to those skilled in the art and will not be described in detail here.
