Description

Technical Field

[0001] The utility model relates to the technical field of mold shell preparation, in particular to a mold shell forming device. Background Art

[0002] Existing mold shell molding equipment can be divided into vertical, horizontal and vertical-horizontal composite types. Plastic products of various shapes are made of thermoplastic plastics or thermosetting plastics using plastic molding molds. Existing mold shell molding equipment for the production of power electronic devices cools the mold through coolant during use, but only cools and dissipates heat on the side. The heat dissipation effect on the injection surface between the molds is very low, and it is necessary to wait for cooling to be completed before re-injection, which greatly affects production efficiency.

[0003] Patent CN219686480U proposes a mold shell molding device. By turning on the motor, the motor output shaft starts to rotate, driving the active bevel gear to mesh and rotate with two sets of driven bevel gears, and then the two sets of driven bevel gears respectively drive the rotating shaft to rotate through the connecting rod. The rotating shaft drives the fan to rotate in the fixed frame as the motor output shaft rotates, and blows air back and forth from the surface of the mold to dissipate the heat of the injection molding surface of the mold. The fan can blow air back and forth on the injection molding surface of the mold through the rotation of the fan, so that the injection molding surface of the mold can be blown to dissipate heat.

[0004] The above scheme uses two sets of fans to blow air to the injection molding surface of the mold to dissipate heat. However, after the conventional shell is processed and sent out, it will dissipate heat in the mold. However, after being sent out, the surface still has a certain temperature, and it is easy to get burned by human contact. According to the technical method in the scheme, air cooling is used for heat dissipation, but the contact surface between the shell and the fan cold air cannot be fully covered, resulting in low efficiency of air cooling.

An exhaust port 11 is provided on one side of the fan box 1, and a water-cooling heat dissipation system and an ejection mechanism of the prior art are disposed inside the lower mold cavity 12. The upper mold plate 23 and the lower mold cavity 12 are driven by the cylinder 21 to cooperate, and the product is injection molded and then ejected. After the product is clamped by the clamping assembly 4, the driving assembly 3 drives two groups of cooling fans 35 to dissipate heat and blow air to the product, and then the clamping assembly 4 sends it out.

[0024] In this embodiment, the driving assembly 3 includes an inner gear ring 33, and the outer edge of the upper disk 22 is rotatably mounted with the inner gear ring 33 through a bearing, and the vertical plate 34 is fixed to the inner gear ring 33. A motor 31 is fixed to one side of the upper disk 22, and a gear 32 is fixed to the output end of the motor 31. The gear 32 is meshed and connected with the inner gear ring 33. When the motor 31 is turned on, the gear 32 is driven to rotate, and the gear 32 is meshed with the inner gear ring 33, thereby driving the two sets of cooling fans 35 to circulate and dissipate heat from the surface of the outer shell.

[0025] In this embodiment, the clamping assembly 4 includes a slide groove 41 and a slide plate 45. The upper disc 22 is provided with slide grooves 41 on both sides perpendicular to the vertical plate 34, and a slide frame 43 is slidably connected inside the slide groove 41. The bottom of the upper disc 22 is located on one side of the slide frame 43 and a first electric push rod 42 is fixed thereto, and the extended end of the first electric push rod 42 is fixed to the slide frame 43. A screw rod assembly 44 is installed inside the slide plate 45, and two slide plates 45 sliding along the slide frame 43 are meshedly installed on the surface of the screw rod assembly 44. An electromagnetic clamp 47 is provided at the bottom of the slide plate 45, and the bottom of the slide plate 45 is rotatably connected to the first electric push rod 42 through a rotating shaft. There are two electric push rods 46, and the extended end of the second electric push rod 46 is rotatably connected to the electromagnetic clamp 47 through a rotating shaft. According to the shape and size of the product, the second electric push rod 46 mobilizes the electromagnetic clamp 47 to rise and fall, and rotates a certain clamping position through manual control or electric drive. The electromagnetic clamp 47 is clamped on the top of the product (in this process, the positions of the two slides 45 can be adjusted by the screw assembly 44 to change the clamping position of the electromagnetic clamp 47. The screw assembly 44 is a common electrically driven bidirectional screw structure). After the heat dissipation is completed, the first electric push rod 42 drives the slide frame 43 to slide along the slide groove 41 to send the product out of the injection molding area.

[0026] In this embodiment, a receiving groove 14 for receiving the electromagnetic clamp 47 and the second electric push rod 46 is opened on the surface of the lower disc 13. Through the setting of the receiving groove 14, the result of the clamping assembly 4 can be received to avoid affecting the merging of the upper mold plate 23 and the lower mold cavity 12.

[0027] In this embodiment, a protective cloth is provided on the outer edge of the lower disc 13, and the top of the protective cloth of the lower disc 13 is buckled with the upper disc 22 through a hook. Figure 1 Unnumbered, after the upper disc 22 and the upper template 23 are raised, the protective cloth will be pulled to wrap the entire heat dissipation area. Then, when the heat dissipation fan 35 dissipates heat to the product, the air outlet of the fan box 1 sucks the hot air generated by the heat dissipation and sends it out from the exhaust port 11 to prevent the hot air from scalding the staff. When sending out the outer shell, the part where the protective cloth is buckled with the upper disc 22 can be removed (this technical method is the same as the principle of hanging curtains).

[0028] When the device is in use, the cylinder 21 drives the upper mold plate 23 and the lower mold cavity 12 to cooperate, and the product is injection molded and then ejected. According to the shape and size of the product, the second electric push rod 46 mobilizes the electromagnetic clamp 47 to rise and fall, and rotates a certain clamp through manual control or electric drive. The electromagnetic clamp 47 is clamped on the top of the product, and the motor 31 is turned on to drive the gear 32 to rotate. The gear 32 engages with the inner ring 33, and then drives the two sets of cooling fans 35 to rotate in a cycle to dissipate heat from the surface of the outer shell. After the heat dissipation is completed, the first electric push rod 42 drives the slide frame 43 to slide along the slide groove 41 to send the product out of the injection molding area.
