[0004] The second is that the precise quantitative form of the material quantity in the batching process is not good. The quantitative function used to control each plastic toy is generally realized by the detection function of the gravity sensor. Detection means that compensation is required, and the entire quantitative process takes a long time. In this regard, it is also necessary to develop a special batching system to complete the precise quantitative measurement of each unit amount in the injection molding process. Summary of the invention

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figure 1 and Figure 2 As shown, the fully automatic injection molding machine includes a frame 1 and a batching system 2 arranged on the frame 1 for quantitative batching, a pushing system 3 for conveying materials, an injection system for injecting materials into a mold, a clamping system with a mold and used for processing and forming products, a cooling system for quickly cooling the molded products, and a control system for controlling the operation of various parts of the injection molding machine.

[0033] like Figure 3 and Figure 4As shown, the cooling system includes a heat dissipation component, a pushing hydraulic cylinder 4 fixedly arranged on the frame 1, and a heat absorber 5 fixedly arranged at the end of the piston rod of the pushing hydraulic cylinder 4. The heat absorber 5 is made of copper, and the heat absorber 5 can be attached to the mold surface when the pushing hydraulic cylinder 4 is in contact with the mold surface.

[0034] The heat dissipation component includes a heat dissipation radiator 6 fixedly arranged on a bracket and a heat dissipation hose 7 passing through the interior of a heat absorber 5. The heat dissipation radiator 6 has a plurality of small channels. The two ends of the heat dissipation radiator 6 are respectively an inlet and an outlet. The two ends of the heat dissipation hose 7 are respectively connected to the inlet and the outlet. The heat dissipation hose 7 and the small channels are filled with coolant. A water pump 8 is also fixedly arranged on the heat dissipation radiator 6. The water pump 8 is used for circulating the coolant in the heat dissipation hose 7 and the small channels.

[0035] The present invention adopts a water cooling system to quickly dissipate heat for the product after molding. The direct contact between the heat absorber 5 and the mold provides a more effective heat conduction benefit. Then, the coolant circulates to the heat dissipation radiator 6. The heat dissipation radiator 6 has a large area of ​​contact with the air to complete the heat exchange with the air, providing a rapid heat dissipation effect.

[0036] The heat sink 6 is provided with a plurality of copper heat sinks 9, and a plurality of heat sink fans 10 are attached to the heat sink 6. The air convection effect is increased, and the efficiency of heat transfer is faster.

[0037] The heat dissipation components have four groups and are circumferentially distributed around the heat absorbing body 5. The front end of the heat absorbing body 5 is provided with a heat absorbing sheet 11 for contacting the mold surface. The heat absorbing sheet 11 is made of nickel-phosphorus alloy.

[0038] In addition, a refrigerator can be designed in the injection molding machine, and the heat dissipation radiator 6 can be placed in the refrigerator, and the heat dissipation effect can be very good. Alternatively, a compressor can be provided to obtain ice water, and then the heat dissipation radiator 6 can be placed in the ice water. Compared with the contact between the heat dissipation radiator 6 and the air, the heat conduction effect of the contact with liquid such as ice water will be better.

[0039] like Figure 5 and Figure 6 As shown, the batching system 2 includes a support body 12, a raw material barrel 13 and a feed plate 14 fixedly arranged on the support body 12, a transposition plate slidably arranged transversely relative to the support body 12, a quantitative cup 15 fixedly arranged on the transposition plate, and a linear drive device for driving the transposition plate to perform transverse displacement movement;

[0040] A discharge port 16 is provided at the bottom of the raw material barrel 13, and a discharge port 17 is provided on the discharge plate 14. The discharge port 16 and the discharge port 17 are staggered.

[0041] The dosing cup 15 is connected vertically, and when the dosing cup 15 is laterally displaced to two extreme positions along with the transposition plate, it is exactly aligned with the discharge port 16 and the discharge port 17 respectively;

[0042] The upper surface of the quantitative cup 15 is arranged on the same plane as the upper surface of the transposition plate, and the transposition plate is arranged face to face with the discharge port 16. When the quantitative cup 15 leaves the discharge port 16, the transposition plate realizes the function of blocking the discharge port 16. The lower surface of the quantitative cup 15 is fitted with the upper surface of the discharge plate 14. When the quantitative cup 15 leaves the discharge port 17, the discharge plate 14 realizes the function of blocking the bottom of the quantitative cup 15.

[0043] The present invention uses a quantitative cup 15 as an intermediate transmission medium. When the quantitative cup 15 is filled with material, it can be defined as a unit amount of material. When the quantitative cup 15 is shifted to align with the discharge port 16 along with the transposition plate, the material in the raw material barrel 13 will instantly fill the quantitative cup 15 under the action of gravity, and then the quantitative cup 15 leaves the discharge port 16 and moves toward the lower feed port 17. During this process, the upper surface of the transposition plate will block the discharge port 16 to prevent the material in the raw material barrel 13 from flowing out. Then, when the quantitative cup 15 moves to align with the lower feed port 17, a unit amount of material in the quantitative cup 15 will flow out from the lower feed port 17 in time, which is equivalent to completing a unit amount of material taking function from the lower feed port 17. Then the quantitative cup 15 moves back to the discharge port 16 to feed the material. When the quantitative cup 15 leaves the lower feed port 17, the bottom of the quantitative cup 15 will fit with the lower feed plate 14 to produce a blocking function. Therefore, each movement cycle will automatically complete a unit amount of batching function, achieving a very accurate quantitative batching function.

[0044] In conventional mechanics, linear drive devices can be made of cylinders, screws, and racks and pinions. Each form has its own advantages and disadvantages, including:

[0045] The pneumatic cylinder is the easiest to implement and is more suitable for the present invention in terms of efficiency. However, the pneumatic cylinder needs to be equipped with a positioning function during the extension and retraction of the piston rod, and the driving speed of the pneumatic cylinder cannot guarantee a comprehensive stability.

[0046] The threaded screw is actually a screw drive, which is a relatively expensive form of transmission. Its advantage is that the precision is very high. However, the screw drive requires the motor to operate at high speed, that is, the screw must rotate many times to achieve the transmission purpose, and the efficiency is relatively slow. Although it can be used, it is not very suitable for the station switching movement of the present invention.

[0047] Therefore, after many considerations by the applicant, it is believed that rack and pinion is the most suitable transmission form for the present invention, which has high efficiency, good stability, and sufficient precision to cope with the station switching movement.

[0048] In addition, forms such as crank sliders and pulleys that can achieve linear motion can also be used in the present invention.

[0049] Under the premise of adopting the gear rack, the present invention also makes additional design on the back and forth driving function.

[0050] like Figures 7 to 9 As shown, the linear drive device includes a transverse slide rail 18 and a vertical slide rail 19 fixedly arranged on the bracket body 12, a forward rack 20 and a backward rack 21 symmetrically fixedly arranged on the transposition plate, a driving frame 22 vertically slidably arranged on the transverse slide rail 18, a driving member 23 fixedly arranged on the driving frame 22 and having a main shaft downwardly arranged and capable of outputting rotational power, and a switching gear 24 fixedly arranged on the main shaft end of the driving member 23;

[0051] The transposition plate is slidably arranged on the transverse slide rail 18;

[0052] The horizontal slide rail 18 and the vertical slide rail 19 are perpendicular to each other and level with the ground;

[0053] The teeth of the forward rack 20 and the backward rack 21 are arranged opposite to each other, and the switching gear 24 is located between the forward rack 20 and the backward rack 21. The switching gear 24 can be respectively connected with the forward rack 20 and the backward rack 21 through the sliding action of the driving frame 22 on the transverse slide rail 18. When the switching gear 24 is connected with the forward rack 20, the switching gear 24 can drive the forward rack 20 to move forward with the transposition plate to shift the quantitative cup 15 from the feeding station to the unloading station. When the switching gear 24 is connected with the backward rack 21, the switching gear 24 can drive the backward rack 21 to move backward with the transposition plate to shift the measuring cup from the unloading station to the feeding station.

[0054] Under the action of the switching component, the driving frame 22 automatically disengages the switching gear 24 from the forward rack 20 and engages with the backward rack 21 when the metering cup 15 shifts to the unloading station, and disengages the switching gear 24 from the backward rack 21 and engages with the forward rack 20 when the metering cup 15 shifts to the replenishing station.

[0055] The metering cup 15 as the material transmission medium is fixed on the transposition plate, so only the moving form of the transposition plate needs to be designed.

[0056] As shown in the figure and combined with the above discussion, the switching gear 24 in the present invention will switch positions after each movement. When the switching gear 24 switches to the forward rack 20 for docking, the driving member 23 will drive the forward rack 20 to move, and the forward rack 20 moves forward with the transposition plate, and the quantitative cup 15 gradually shifts from the feeding station to the unloading station. When the switching gear 24 switches to the backward rack 21 for docking, the driving member 23 will drive the backward rack 21 to move, and the backward rack 21 moves backward with the transposition plate, and the quantitative cup 15 gradually shifts from the unloading station to the feeding station.

[0057] The important design point of the present invention is how to realize the automatic switching of the switching gear 24 to the forward rack 20 and the backward rack 21. The present invention provides the following technical means:

[0058] The switching component includes two switching components, and the switching components include an extrusion rod 25, a lifting rod 26 and a fixing rod;

[0059] The extrusion rod 25 is formed by connecting a horizontal rod and a vertical rod with their ends fixed vertically. A first inclined surface 28 is provided on the horizontal rod. The bottom ends of the vertical plates in the two switching components are fixedly arranged on the forward rack 20 and the backward rack 21 respectively.

[0060] The fixed rods in the two switching assemblies are fixedly arranged on the vertical slide rails 19 and are respectively located on both sides of the driving frame 22. The fixed rods are provided with hook bodies 27, and the lifting rods 26 are provided with hook holes. The hook holes are located on the hook bodies 27 so that the lifting rods 26 can be freely hung on the fixed rods.

[0061] A second inclined surface 29 is provided at the bottom of the lifting rod 26. When the extrusion rod 25 moves along with the transposition plate, the second inclined surface 29 will contact the first inclined surface 28 so that the extrusion rod 25 pushes the lifting rod 26 upward.

[0062] A third inclined surface 30 is provided at the top of the lifting rod 26, and fourth inclined surfaces 31 are provided on both sides of the driving frame 22. When the lifting rod 26 rises, its third inclined surface 30 will fit with the fourth inclined surface 31 on that side to push the driving frame 22 to the other side. When the fourth inclined surfaces 31 on both sides of the driving frame 22 are pushed to the limit position respectively, the switching gear 24 just docks with the forward rack 20 or the backward rack 21.

[0063] The two switching components are used to realize the automatic displacement of the switching gear 24. Since the switching gear 24 is fixed to the main shaft end of the driving member 23, to shift the position of the switching gear 24 is actually to move the position of the driving member 23. Since the driving member 23 is fixed on the driving frame 22, the movement can be completed by only shifting the driving frame 22.

[0064] like Figure 8 and Fig. 9As shown, the squeezing rod 25 in the switching assembly is fixedly arranged relative to the forward rack 20 (or the backward rack 21), and the lifting rod 26 is hung on the hook body 27 under the action of gravity. When the squeezing rod 25 moves with the forward rack 20 (or the backward rack 21), the first inclined surface 28 will be in face-to-face contact with the second inclined surface 29. Because the lifting rod 26 is only limited in the height direction, the lifting rod 26 will be pushed and lifted after the squeezing effect between the first inclined surface 28 and the second inclined surface 29. After the lifting rod 26 is lifted, the third inclined surface 30 above the lifting rod 26 will squeeze the fourth inclined surface 31 on the driving frame 22, and the driving frame 22 can only move on the vertical slide rail 19, so after the squeezing effect between the third inclined surface 30 and the fourth inclined surface 31, the driving frame 22 will be pushed to the other side, and the driving frame 22 originally close to the forward rack 20 (or the backward rack 21) will move to the backward rack 21 (or the forward rack 20) ​​on the other side, completing the transposition and handover function.

[0065] The above repetitive motion can be achieved by setting the two switching components at the extreme positions of the motion respectively, and automatically changing the driving direction when the motion is completed. Of course, because the lifting rod 26 is freely hung and does not play a role of restraint, every time the driving frame 22 completes a position switch, the driving frame 22 should actually be locked and limited at the same time, but because the driving frame 22 has a driving member 23, its own weight is not low, so the gravity of the driving frame 22 itself is converted into the friction force formed by the contact surface with the vertical slide rail 19, which plays a limiting effect, that is, the driving frame 22 itself has a certain self-locking ability, unless the third inclined surface 30 and the fourth inclined surface 31 contact to generate external force, otherwise the driving frame 22 will not move easily.

[0066] It should be understood that in the claims and description of the present invention, all "including..." should be understood as an open-ended meaning, that is, its meaning is equivalent to "at least contains...", and should not be understood as a closed meaning, that is, its meaning should not be understood as "only includes...".

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
