Moreover, for high-precision injection molding and low-precision injection molding, the quality requirements for the outer shell are different, and it is impossible to guarantee both the molding and demolding efficiency and the molding quality. This phenomenon has become a problem that needs to be urgently solved by people in this field. Summary of the Invention

[0029] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0030] See also Figures 1-12 The present invention provides a technical solution: a continuous automobile electric storage box outer shell injection molding device, comprising an injection molding machine, an upper mold 1, a lower mold 2 and a continuous injection molding mechanism, wherein the upper mold 1 and the continuous injection molding mechanism are both installed on the injection molding machine, and the continuous injection molding mechanism comprises a connecting rod 3, a hydraulic chamber 4 and two support plates 5;

[0031] The inner wall of the hydraulic chamber 4 is slidably connected to a hydraulic plate 41. A through hole is provided above the hydraulic chamber 4, and the connecting rod 3 is inserted into the through hole. The upper surface of the hydraulic plate 41 is connected to the bottom of the lower mold 2 via a bearing between the connecting rod 3. Two support plates 5 are fixedly mounted on the left and right sides of the bottom of the hydraulic chamber 4 and fixed to the injection molding machine. The upper mold 1 and the lower mold 2 fit together. The bottom of the hydraulic plate 41 is connected to the bottom of the inner wall of the hydraulic chamber 4 by a spring.

[0032] The injection molding machine injects liquid plastic into the upper mold 1, and then enters the lower mold 2 to perform injection molding of the outer shell of the automobile electric storage box. After molding is completed, the operator holds the connecting rod 3 and presses it downward. The connecting rod 3 drives the lower mold 2 to move downward. At the same time, the connecting rod 3 presses the hydraulic plate 41 to slide downward along the inner wall of the hydraulic cavity 4. The spring is deformed under force. The operator takes the molded outer shell of the automobile electric storage box out of the lower mold 2, and then releases the connecting rod 3. The spring generates a reaction force to push the hydraulic plate 41 to reset, thereby resetting the lower mold 2 and re-fitting it with the upper mold 1. The molding work is performed again, and continuous molding work is performed. The injection molding efficiency is greatly improved, the production volume is increased, and the operation is simple.

[0033] The lower mold 2 is provided with a hollow layer inside, and the connecting rod 3 is provided with a liquid hole 31 inside. The upper and lower ends of the liquid hole 31 are connected to the bottom of the hydraulic plate 41 and the inside of the hollow layer respectively. The bottom of the hydraulic plate 41 is filled with coolant.

[0034] When the hydraulic plate 41 slides downward along the inner wall of the hydraulic chamber 4, the coolant below the hydraulic plate 41 enters the hollow layer of the lower mold 2 through the liquid hole 31, thereby quickly cooling the outer shell of the formed automobile electric storage box, thereby facilitating rapid demoulding and further improving molding efficiency;

[0035] Embodiment 1;

[0036] After the connecting rod 3 is pressed down, the operator rotates the connecting rod 3 so that it rotates through the bearing, thereby driving the lower mold 2 to rotate. During the rotation, the lower mold 2 can be shaken, thereby further accelerating the demoulding speed.

[0037] The bottom of the hydraulic chamber 4 is provided with a hole, and a rotating rod 42 is slidably connected inside the hole. A threaded hole is provided inside the rotating rod 42, and a screw rod 421 is threadedly connected inside the threaded hole. An insert block is fixed to the upper end of the screw rod 421.

[0038] The upper half of the liquid hole 31 is circular, and the lower half is conical. The left and right sides of the insert block are also conical. The insert block fits with the liquid hole 31, and the taper of the insert block is smaller than the taper of the lower half of the liquid hole 31. A slot is provided at the bottom of the hydraulic plate 41, and the insert block is inserted into the slot.

[0039] Example 2:

[0040] like Figure 8 As shown, when the hydraulic plate 41 moves downward, the coolant at the bottom enters the liquid hole 31. At the same time, the insert block is inserted into the liquid hole 31. Due to the tapered lower half of the liquid hole 31 and the tapered insert block, when the insert block is inserted into the liquid hole 31, the gap between the insert block and the inner wall of the liquid hole 31 gradually decreases as the hydraulic plate 41 moves downward. During the descent of the hydraulic plate 41, the flow rate of the coolant through the gap gradually accelerates, thereby accelerating the flow rate of the coolant entering the lower mold 2 and improving the cooling intensity. The further the hydraulic plate 41 goes downward, the more the operator gradually increases the downward pressure on the connecting rod 3, and the downward speed of the connecting rod 3 is controlled, thereby improving the stability of the downward movement of the lower mold 2 and ensuring the molding quality.

[0041] A special-shaped wheel 43 is provided at the bottom of the rotating rod 42, and the special-shaped wheel 43 is connected to the bottom of the screw 421. The bottom end of the screw 421 is connected to a nut 44, and the special-shaped wheel 43 is fixed by the nut 44;

[0042] A guide rail 51 is fixed between the two support plates 5, and a slider 52 is slidably connected inside the guide rail 51. A striking rod 521 is fixed to the left side of the slider 52, and a push rod 522 is fixed to the right side of the bottom. After the special-shaped wheel 43 rotates, it contacts the push rod 522. The right side of the slider 52 is connected to the right support plate 5 by a spring.

[0043] Example 3:

[0044] like Figure 11When the cam 521 is in the state of rotation and the cam 522 is in the state of rotation, the cam 522 is in the state of rotation and the cam 522 is in the state of rotation.

[0045] Example 4:

[0046] When the coolant needs to be cooled, the operator takes out the molded outer shell of the automobile electric storage box, lifts the connecting rod 3, and ensures that the lower mold 2 is not inserted into the upper mold 1. The coolant in the lower mold 2 re-enters the hydraulic cavity 4. Then, the connecting rod 3 is quickly rotated, thereby driving the insertion block to rotate quickly through the liquid hole 31, and quickly stirring the coolant in the hydraulic cavity 4 to quickly dissipate the heat of the coolant, avoid affecting the subsequent cooling effect, and the coolant can be reused continuously to reduce costs.

[0047] The insert block includes an upper insert block 45 and a lower insert block 46 . A circular hole is provided at the bottom of the upper insert block 45 and in the middle of the lower insert block 46 , and the screw rod 421 is inserted into the circular hole.

[0048] Two protrusions are provided above the rotating rod 42, and the two protrusions are arranged vertically at 90 degrees. A limit block is fixed on one side of the screw rod 421, and the limit block is located between the two protrusions.

[0049] Embodiment 5:

[0050] like Figure 9 and Figure 10As shown, the outer shell of the automobile electric storage box with high molding precision, before the operator presses down the connecting rod 3, the operator loosens the nut 44, holds the rotating rod 42, and rotates the screw 421 to drive the lower plug 46 to rotate. Due to the limitation of the limit block and the protrusion, the screw 421 can only rotate at 90 degrees. After the rotation is completed, the lower plug 46 and the upper plug 45 are vertical. After that, after pressing down the connecting rod 3, only the upper plug 45 is embedded in the liquid hole 31, and the lower plug 46 is fixed at the bottom of the hydraulic plate 41. The outer wall of the upper plug 45 is aligned with the inner wall of the liquid hole 31. The gap between them is only affected by the upper plug-in block 45, so the gap is larger than the gap after the lower plug-in block 46 is embedded in the liquid hole 31, the liquid flow rate is slowed down, the pressure of the connecting rod 3 moving downward is reduced, and the coolant flow rate is increased. At this time, the operator repeatedly plugs and pulls out the connecting rod 3 up and down multiple times, thereby performing high-intensity cooling multiple times, so that the outer shell of the automobile electric storage box can be smoothly detached through high-intensity cooling, and will not affect the surface quality of the outer shell of the automobile electric storage box. The downward pressure of the connecting rod 3 is small, which is relatively labor-saving, the plugging and unplugging is smoother, and the cooling efficiency is relatively improved.

[0051] An elastic spring 47 is provided between the lower insert block 46 and the rotating rod 42;

[0052] After the lower insert block 46 and the upper insert block 45 are vertical, the connecting rod 3 is pressed down. After the bottom of the hydraulic plate 41 contacts the lower insert block 46, the lower insert block 46 is continued to be squeezed. The lower insert block 46 squeezes the elastic spring 47 to deform, so that the hydraulic plate 41 can continue to move downward without restriction, ensuring the amount of coolant entering the lower mold 2 each time to ensure the cooling effect.

[0053] A U-shaped groove 431 is provided in the middle of the special-shaped wheel 43. In the initial state, the special-shaped wheel 43 is concentric with the screw 421. After the special-shaped wheel 43 moves, it becomes eccentric with the screw 421.

[0054] Example 6:

[0055] like Figure 12 As shown, the outer shell of the electric storage box for automobiles has poor molding accuracy. At this time, after the operator loosens the nut 44, he does not rotate the screw 421, but moves the special-shaped wheel 43 so that it moves on the screw 421 through the U-shaped groove 431. After the movement is completed, the special-shaped wheel 43 is fixed again by the nut 44. After that, the operator presses down the connecting rod 3, and there is no need to lift it, but continuously rotate the connecting rod 3, so that the special-shaped wheel 43 continues to rotate. After the special-shaped wheel 43 moves, it squeezes the top rod 522, which increases its moving stroke, increases the accumulated force of the spring, strengthens the reaction force, and increases the vibration intensity, so that the outer shell of the electric storage box for automobiles in the lower mold 2 can be quickly loosened with high intensity vibration multiple times to quickly remove the outer shell of the electric storage box for automobiles.
