Referring to fig. 1 to 3, a continuously injection moldable hardware mold 40 mechanism according to an embodiment of the present invention includes a base 10, a turntable 20, a lifting plate 30, and a hardware mold 40. The rotary table 20 is rotatably arranged at the upper end of the machine base 10; the lifting plate 30 is arranged above the turntable 20 in a lifting manner, and the lifting plate 30 is connected with the machine base 10 through a movable rod 31; hardware mould 40 includes mould 41 and lower mould 42, goes up mould 41 and sets up the lower terminal surface at lifter plate 30, and lower mould 42 sets up on carousel 20, and the quantity of lower mould 42 is two at least. It should be noted that if the injection molding time is shorter, more lower molds 42 may be provided, and three or four or even more lower molds may be provided. When the injection molding time is short, the speed of manually putting hardware can be increased. Taking three lower dies 42 as an example, when one of the lower dies 42 is just below the upper die 41, hardware can be placed in the other two lower dies 42, after injection molding is completed, the injection molded lower die 42 can be immediately moved out of an injection molding station through the turntable 20, the lower die 42 with the hardware placed therein is moved to the position below the upper die 41 through the turntable 20, the other lower die 42 with the hardware placed therein can enter a state to be injection molded, and new hardware can be placed in the moved injection molded lower die 42. More lower mould 42 stations can provide the hardware of placing for the longer time for the technical staff, and the fast-speed flow of moulding plastics simultaneously can improve the efficiency of moulding plastics, still can improve hardware mould 40's utilization ratio.

The upper die 41 is attached to or separated from the lower die 42 through the lifting plate 30, when the lifting plate 30 moves downwards through the movable rod 31, the upper die 41 on the lower end surface of the lifting plate 30 is driven to move downwards, the lower end surface of the upper die 41 can be attached to the upper end surface of the lower die 42, and when the upper die and the lower die are attached to each other, an injection molding cavity can be formed between the upper die and the lower die 42, so that injection molding can be carried out. However, it should be noted that the hardware is manually placed in the cavity on the upper end surface of the lower mold 42 before injection molding. After the injection molding is completed, the lifting plate 30 moves upwards through the movable rod 31 to drive the lower mold 42 to move upwards, the lower end surface of the upper mold 41 can be separated from the upper end surface of the lower mold 42, and the demolding operation can be performed after the separation. After the upper die 41 and the lower die 42 are separated and demolded, the lower die 42 which is demolded can be rotated to a station for placing hardware through the turntable 20, the hardware is placed on the lower die 42 manually, and the lower die 42 which is placed with the hardware is rotated to the position below the upper die 41 on the lifting plate 30 by waiting for the turntable 20. When the turntable 20 rotates the lower mold 42 to a position right below the upper mold 41, the lifting plate 30 drives the upper mold 41 to move down to fit the lower mold 42 for injection molding, thereby completing the injection molding. When a previous lower die 42 rotates to the lower part of the upper die 41, hardware is placed on another lower die 42, injection molding of the previous lower die 42 is completed, the lower die 42 can rotate to the position under the upper die 41 through the turntable 20, and therefore injection molding production of the hardware can be conducted all the time efficiently as circulation, and further the purpose of continuous injection molding is achieved, so that production time is saved, and production efficiency of the hardware injection molding is improved.

In some embodiments of the present invention, a first driving member is disposed in the machine base 10, an output end of the first driving member is connected to the rotating disc 20, and the first driving member drives the rotating disc 20 to rotate. As can be seen from the figure, the lifting plate 30 may be triangular, and the number of the movable rods 31 is three, the three movable rods 31 are respectively connected to three corners of the lifting plate 30, and the other end is inserted into the machine base 10. It can be understood that one of the movable rods 31 is inserted through the center of the turntable 20, and the center of the turntable 20 is inconvenient for the first driving member to be disposed. In order to enable the turntable 20 to rotate smoothly, a hollow shaft gear (not shown) may be disposed below the turntable 20, the hollow shaft gear is connected to the turntable 20 and connected to a driving gear, and an output end of the first driving member may be connected to the driving gear, so as to drive the hollow shaft gear and further drive the turntable 20 to rotate. The movable rod 31 can penetrate through the hollow rotating shaft of the hollow gear of the rotating shaft. In this way, the lifting plate 30 can perform both the lifting operation and the rotating operation of the turntable 20. The lifting plate 30 drives the upper die 41 to move up or down, and the turntable 20 can drive the lower die 42 to move to a position right below the lower die 42 or to a position where hardware is placed.

In some embodiments of the present invention, the first driving member is a stepper motor, and the speed of the turntable 20 is adjustable. The speed of the turntable 20 can be adjusted according to the actual conditions of operation. If the time required for injection molding is shorter, the molding speed is higher, so that the speed of the turntable 20 can be increased by the stepping speed regulating motor to increase the speed of the lower mold 42, thereby improving the efficiency of producing injection molded parts; if the hardware placing speed is slow, the rotating speed of the rotating disc 20 is also slow, so that the speed of the rotating disc 20 can be slowed down through the stepping speed regulating motor, and the hardware placing speed is adapted to the speed of a technician for placing the hardware. However, it should be emphasized that when the turntable 20 is attached to the upper mold 41 and the lower mold 42 for injection molding, the turntable is stationary relative to the lifting plate 30, and the stationary lifting plate 30 facilitates attachment between the upper mold 41 and the lower mold 42 for injection molding, so the selected first driving member needs to meet the requirement of intermittent pulse output, so the first driving member may select the motor of the step speed regulating motor provided in this embodiment, when the turntable 20 rotates the lower mold 42 to a position right below the lower mold 42, the step speed regulating motor stops outputting to the turntable 20, and when the lower mold 42 is stationary relative to the upper mold 41, the lifting plate 30 moves down to drive the upper mold 41 to move down to attach the lower end surface of the upper mold 41 to the upper end surface of the lower mold 42, and then injection molding can be performed.

In some embodiments of the present invention, the machine base 10 is provided with a second driving member, an output end of the second driving member is connected to the movable rod 31, and the second driving member drives the movable rod 31 to move up and down. The output end of the second driving element drives the movable rod 31 to move upwards, the number of the movable rods 31 is continuously three as an example, for saving the occupied space of the base 10, only one second driving element can be arranged, the output end of the second driving element can be simultaneously connected with the lower ends of the three movable rods 31, when the second driving element outputs, the three movable rods 31 can be simultaneously moved upwards or downwards, it is ensured that the lifting plate 30 at the upper end of the movable rod 31 keeps a horizontal state, thereby it can be ensured that the lower end face of the upper die 41 keeps a horizontal state, and further the lower end face of the upper die 41 can be attached to the upper end face of the lower die 42, and finally, the smooth injection molding work can be ensured.

In some embodiments of the utility model, further, the second drive member may select a component of a hydraulic cylinder (not shown) for output. Connect the lower extreme of movable rod 31 with the output of pneumatic cylinder, when moulding plastics the completion, the output of pneumatic cylinder shifts up, can promote movable rod 31 to shift up, thereby promote lifter plate 30 to move up, and then drive and go up mould 41 and shift up, carousel 20 can shift out the station of moulding plastics with the lower mould 42 of moulding plastics, the lower mould 42 that has placed the hardware simultaneously shifts to going up mould 41 under, treat that the output of pneumatic cylinder drives movable rod 31 and moves down, it moves down to drive lifter plate 30, the lower terminal surface of going up mould 41 is laminating lower mould 42 up end promptly, can carry out the work of moulding plastics afterwards. It is conceivable that the second driving member may be configured as an air cylinder in addition to the hydraulic cylinder mentioned above, and even may be configured as a motor to drive a rack.

Referring to fig. 1, in some embodiments of the present invention, a through hole (not shown) is formed in the middle of the lifting plate 30, and an injection gun (not shown) is connected to the upper end of the lifting plate 30 and is communicated with an injection hole 411 formed in the upper end of the upper mold 41 through the through hole. Because the upper end surface of the upper die 41 is attached to the lower end surface of the lifting plate 30, a through hole can be formed in the position, corresponding to the upper die 41, of the lifting plate 30, an injection molding gun is convenient to install on the lifting plate 30, the injection molding gun can be communicated with an injection molding hole 411 in the upper end of the upper die 41 through the through hole, molded raw materials are injected into the hardware die 40 from the injection molding gun, and injection molding can be completed. It can be understood that the connection mode of the injection molding gun and the lifting plate 30 can be a threaded connection mode, and the situation that injection molding raw materials overflow from the through hole to pollute the lifting plate 30 and the working environment and further need to be cleaned at the input cost can be avoided. Meanwhile, the other end connected with the injection molding gun is provided with a plastic hose, so that the injection molding gun can move up and down along with the lifting plate 30.

In order to better enable the lower end surface of the upper mold 41 to be correspondingly attached to the upper end surface of the lower mold 42 and improve the yield of injection molded parts, the positioning blocks 413 on the four corners of the upper mold core 412 can enter the positioning cavities 422 on the four corners corresponding to the lower mold core 421 when the upper mold 41 moves downwards, and the injection molding operation can be performed only when the positioning blocks 413 all enter the positioning cavities 422, that is, the upper mold core 412 is tightly attached to the lower mold core 421. It should be noted that the number of the positioning blocks 413 and the positioning cavities 422 may be more than one, and it can be understood that the positioning accuracy can be improved by more positioning blocks 413 matching with the positioning cavities 422, so as to improve the quality of the injection molding work.

Referring to fig. 4 to 6, in some embodiments of the present invention, as described in the above embodiments, the positioning rods 414 are disposed at the corners of the upper mold 41, the positioning holes 423 are disposed at the corners of the lower mold 42, and the positioning rods 414 can be inserted into the positioning holes 423. When the upper die 41 moves downward, the positioning rod 414 can be inserted into the positioning hole 423 to position the upper die 41 and the lower die 42.

In some embodiments of the present invention, the upper mold 41 is detachably mounted on the lower end surface of the elevating plate 30, and the lower mold 42 is detachably mounted on the upper end surface of the turntable 20. It is conceivable that the upper and lower dies 41 and 42 are easily consumable items and need to be replaced frequently because the upper and lower dies 41 and 42 are frequently collided, attached, and the like, and the upper and lower dies 41 and 42 are detachably attached to the lifting plate 30 and the turntable 20, respectively. On the one hand, the replacement can be convenient, on the other hand, different hardware molds 40 can be replaced, and the applicability of the hardware mold 40 mechanism capable of continuous injection molding is improved.
