Description

Technical Field

[0001] This invention relates to the field of sprue cooling technology, specifically to a plastic sprue cooling machine. Background Technology

[0002] In the injection molding process, the sprue is the essential flow path for molten plastic to enter the mold cavity from the injection molding machine nozzle. After the injection molding cycle is completed, the sprue is demolded along with the molded product. As a major scrap material generated from thermoplastic injection molding, sprue has the characteristic of being remelted and processed repeatedly. Its recycling is one of the core links in reducing raw material costs and achieving green and low-carbon production in the injection molding industry. The sprue that has just been demolded is still in a high-temperature state, close to the melting temperature of the plastic. It is soft and highly plastic. If it is directly fed into the crushing equipment for processing, it is very easy to cause problems such as sticking to the blade, melting and clumping, and ineffective shearing. Therefore, it must first undergo a cooling process to fully solidify the sprue before it can be crushed and granulated for recycling. The cooling and solidification efficiency and uniformity of the sprue directly determine the molding quality of the recycled particles in the subsequent crushing process, which is a key process affecting the recycling effect of sprue. Injection molding sprues are mostly thin flow channel structures, where the heat of the material is highly concentrated. Their thin walls and short heat conduction paths make them weak points in the cooling process. Existing sprue cooling equipment uses a continuous cooling feeding method, which easily leads to inconsistent internal and external curing of the sprue material and insufficient overall curing. As a result, after cooling, the sprue material generally has problems such as uneven particle size and excessive powder output during subsequent crushing and recycling, which cannot meet the particle size requirements for direct reuse of recycled material.

[0018] Working Principle: When using this invention, the cooler is installed at the feed inlet of the crusher. High-temperature sprue enters the casing 1 through the feed funnel 11 and is blocked by the first baffle 22, waiting for cooling. After a set time, the electrical control box 16 controls the first electric telescopic rod 26, causing the first baffle 22 to deflect and open, allowing the sprue to fall onto the second baffle 32 for secondary cooling. Then, the first electric telescopic rod 26 drives the first baffle 22 to deflect and reset, waiting for the next feeding of high-temperature sprue. After the secondary cooling reaches the set time, the electrical control box 16 controls the second electric telescopic rod 36, causing the second baffle 32 to deflect and open, allowing the cooled sprue to fall into the crusher. In the crusher, the second electric telescopic rod 36 drives the second baffle 32 to deflect and reset, waiting for the next batch of sprue material to fall, thus achieving phased delayed material feeding. The first mounting base 25 is used to mount the first electric telescopic rod 26. The principle of the first electric telescopic rod 26 driving the first baffle 22 is as follows: when the first electric telescopic rod 26 retracts, it drives the first moving seat 27 to move downwards. The first connecting rod 24 loses the support of the first moving seat 27. Under the action of gravity, the first baffle 22 drives the first connecting shaft 21, which in turn drives the first rotating shaft 23. The first rotating shaft 23 rotates within the first groove 13, causing the first baffle 22 to deflect and open. When the telescopic rod 26 extends, it causes the first movable seat 27 to move upward, pushing the first connecting rod 24. The first connecting rod 24 causes the first rotating shaft 23 to deflect, and the first rotating shaft 23 drives the first connecting shaft 21. The first baffle 22 on the first connecting shaft 21 then rotates and resets. The second mounting seat 35 is used to mount the second electric telescopic rod 36. The principle of the second electric telescopic rod 36 driving the second baffle 32 is as follows: When the second electric telescopic rod 36 extends, it causes the second movable seat 37 to move downward. The second connecting rod 34 loses the support of the second movable seat 37. Under the action of gravity, the second baffle 32 drives the second connecting shaft 31, and the second connecting shaft 31 drives the second rotating shaft. 33. The second rotating shaft 33 rotates within the second groove 15, the second baffle 32 deflects and opens, and when the second electric telescopic rod 36 retracts, it drives the second moving seat 37 to move upward, pushing the second connecting rod 34. The second connecting rod 34 drives the second rotating shaft 33 to deflect, and the second rotating shaft 33 drives the second connecting shaft 31. The second baffle 32 on the second connecting shaft 31 rotates and resets accordingly. The first through groove 12 is used to avoid the first connecting shaft 21, the second through groove 14 is used to avoid the second connecting shaft 31, the first limiting plate 28 is used to limit the first connecting shaft 21, the second limiting plate 38 is used to limit the second connecting shaft 31, and the vent 17 is used for ventilation and heat dissipation.
