[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Demolding refers to a series of operations to remove the object from the ingot mold after injection molding. In traditional injection molding machines, injection and demolding are completed in steps, and sometimes even after the injection molding machine is completed, it is necessary to assist in demolding with external machines or manual methods.

[0003] In the process of opening the punch and die of the injection molding machine demoulding assembly in the prior art, the material easily adheres to the outer wall of the punch or the inner wall of the die, resulting in the material being affected by the fit of the punch or the die after molding, resulting in unsmooth demoulding and reducing the processing efficiency of the device. In this regard, we propose an injection molding machine demoulding assembly. Utility Model Content

The front wall of the fixed block 8 is provided with a number of evenly distributed through holes. A push rod 14 is provided near the front in the through hole, and the push rod 14 extends to the outside of the through hole and is fixedly connected to the rear wall of the second fixed plate 6. The top and bottom of the push rod 14 are fixedly connected to the second limit block 13 near the rear end, and the top and bottom of the inner cavity of the through hole are provided with limit grooves matching the second limit block 13. A push rod 18 is provided in the through hole near the rear of the push rod 14, and the left and right side walls of the push rod 18 are fixedly connected to the third limit block 16 near the front. Limiting holes matching the third limiting block 16 are provided on the inner walls on both sides of the hole, and a second limiting rod 15 is provided in the limiting hole. The front and rear ends of the second limiting rod 15 are fixedly connected to the inner wall of the limiting groove. A second spring 17 is sleeved on the second limiting rod 15 near the rear, and the front and rear ends of the second spring 17 are respectively fixedly connected to the rear inner wall of the limiting groove and the rear wall of the third limiting block 16. A second fixing plate 6 is provided in front of the fixed block 8, and a movable hole is provided on the front wall of the fixed block 8. The inner wall behind the movable hole is fixedly connected to the electric telescopic rod 7, and the front end of the electric telescopic rod 7 is fixedly connected to the rear wall of the second fixing plate 6.

[0025] By setting the isosceles trapezoidal groove 5 and a group of right-angled trapezoidal blocks 4 on both sides, when the punch 9 and the die are closed and the right-angled trapezoidal blocks 4 fit together in the isosceles trapezoidal groove 5, the two right-angled trapezoidal blocks 4 will be driven to move toward each other as the punch 9 and the fixed block 8 move until the two modules 3 are tightly attached to each other and combined into a die. At the same time, when the punch 9 is opened, the two modules 3 move away from each other and break away from contact with the material under the action of the first spring 12, so as not to affect the movement of the material with the punch 9. At the same time, through the setting of the push rod 14, when the fixed block 8 moves forward, the push rod 18 is pushed to be misaligned with the fixed block 8, thereby ejecting the material from the punch 9, thereby achieving stable and smooth demoulding of the device.

[0026] like Figure 2 As shown, a spiral water trough 2 is provided in the module 3 , and a water inlet and a water outlet connected to the interior of the spiral water trough 2 are respectively provided on the left wall near the bottom and the right wall near the top of the module 3 .

[0027] By setting up the spiral water trough 2, the refrigerant can be introduced from the water injection hole through an external water pipe to flow through the inside of the spiral water trough 2, and then discharged through the water outlet, thereby realizing the circulation of the refrigerant inside the spiral water trough 2, effectively conducting away the heat in the mold cavity, thereby effectively improving the cooling effect of the device.

[0028] Working principle: When the present technical solution is used, the electric telescopic rod 7 is turned on to drive the fixed block 8 and the punch 9 to move backward. The setting of a plurality of push rods 14 effectively plays the effect of limiting and stabilizing the fixed block 8. When the right-angled trapezoidal block 4 begins to connect with the isosceles trapezoidal groove 5, the backward movement of the fixed block 8 will drive the upper and lower right-angled trapezoidal blocks 4 to move in the middle, until the two modules 3 are driven to move toward the middle and fit tightly together to form a concave mold. The material is injected into the mold cavity through the injection hole, and the refrigerant is introduced into the water injection hole through the external soft water pipe to flow through the spiral water trough 2, and then discharged through the water outlet to install the device. The internal heat is conducted away, thereby effectively improving the cooling effect of the device. After the process is completed, the electric telescopic rod 7 is turned on to contract and drive the fixed block 8 to move forward. At this time, under the action of the first spring 12, as the isosceles trapezoidal groove 5 releases the constraints of the two right-angled trapezoidal blocks 4, the two modules 3 move back to back and break contact with the material, so as not to hinder the movement of the material with the punch 9, ensuring the stability of the material discharge. When the front end of the ejector rod 18 contacts the push rod 14, the ejector rod 18 and the fixed block 8 are misaligned, thereby pushing the material out and sliding, thereby realizing automatic, stable and smooth material discharge of the device.
