[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides a technical solution: a heat-equalizing hot runner structure, comprising a hot runner body 1, two connecting plates 2 connected to the side walls of the hot runner body 1, and a spiral heating tube body 3 installed on the outer wall of the hot runner body 1;
[0024] The first curved plate 4 and the second curved plate 5 are fitted together between the two connecting plates 2. The outer wall of the first curved plate 4 is connected to two plug-in blocks 7, and the outer wall of the second curved plate 5 is connected to two fixing blocks 8. A fixing groove 9 is provided inside each fixing block 8. The ends of the two plug-in blocks 7 are inserted into the fixing groove 9, and a fastener is provided inside each fixing block 8. By providing the plug-in blocks 7 and the fixing blocks 8, the plug-in blocks 7 and the fixing blocks 8 can be quickly connected and fixed under the action of the fasteners, which is convenient for workers to quickly disassemble and assemble the first curved plate 4 and the second curved plate 5. At the same time, the overall structure is compact, the cost is low, and the practicality is high.
[0025] In a preferred embodiment, the fastener includes a slot 10 and an insertion rod 11;
[0026] A slot 10 is provided inside each plug block 7, and an insert rod 11 is slidably connected to the inside of each fixed block 8, and the bottom end of each insert rod 11 is inserted into the slot 10; by providing fasteners, the plug block 7 can be quickly fixed inside the fixed block 8 after entering the fixed block 8.
[0027] In a preferred embodiment, the outer wall of each insertion rod 11 is connected to a first spring 12, and the other end of each first spring 12 is connected to the outer wall of the fixed block 8; by providing the first spring 12, the stability of the insertion rod 11 inside the slot 10 is enhanced, and at the same time, the insertion rod 11 can be prevented from escaping from the fixed block 8.
[0028] In a preferred embodiment, the inner wall of each fixing groove 9 is connected to a second spring 14, the other end of each second spring 14 is connected to a push plate 13, and the outer wall of each push plate 13 is fitted against the outer wall of the insertion block 7; by providing the push plate 13 and the second spring 14, when the insertion rod 11 is disengaged from the inside of the slot 10, the push plate 13 can quickly push the insertion block 7 out of the inside of the fixing block 8.
[0029] In a preferred embodiment, two limit blocks 15 are connected to the inner wall of each fixing groove 9; by providing the limit blocks 15, the movement of the push plate 13 can be limited, thereby preventing the push plate 13 from escaping from the inside of the fixing block 8.
[0030] In a preferred embodiment, the upper and lower ends of the first curved plate 4 and the second curved plate 5 are connected with sealing rings 6; by providing the sealing rings 6, the upper and lower ends of the first curved plate 4 and the second curved plate 5 can be fitted on the outer wall of the connecting plate 2, thereby increasing the sealing between the first curved plate 4 and the second curved plate 5 and the connecting plate 2, and reducing the temperature overflow of the spiral heating tube body 3.
[0031] In a preferred embodiment, the lower end of each insertion rod 11 is configured to be inclined; through the inclined configuration, when the insertion block 7 enters the fixed block 8 to squeeze the insertion rod 11, there is no need to pull the insertion rod 11, the insertion rod 11 will automatically move upward, thereby facilitating the subsequent insertion rod 11 to enter the interior of the slot 10 and complete the locking between the insertion block 7 and the fixed block 8.
[0032] Working principle: When the main body 3 of the spiral heating tube is to be repaired, the first curved plate 4 and the second curved plate 5 need to be disassembled;
[0033] By pulling the insertion rod 11 and making the lower end of the insertion rod 11 disengage from the slot 10, the push plate 13 will quickly push the insertion block 7 out of the fixing groove 9 under the elastic action of the second spring 14, thereby separating the first curved plate 4 and the second curved plate 5, thereby facilitating the maintenance of the spiral heating tube body 3. After the first curved plate 4 and the second curved plate 5 are separated, the insertion rod 11 can be released, and the insertion rod 11 will quickly fall back under the elastic action of the first spring 12 until it enters the fixing groove 9.
[0034] When the main body 3 of the spiral heating tube is repaired, the first curved plate 4 and the second curved plate 5 need to be installed;
[0035] By fitting the upper and lower ends of the first curved plate 4 and the second curved plate 5 between the two connecting plates 2, the plug block 7 is allowed to enter the interior of the fixed block 8, thereby causing the plug block 7 to squeeze the plug rod 11. Since the lower end of the plug rod 11 is inclined, when the end of the plug block 7 squeezes the plug rod 11, the plug rod 11 will move upward inside the fixed block 8 until the plug block 7 fits against the outer wall of the fixed block 8 and cannot go any deeper. The plug rod 11 will quickly move back under the elastic action of the first spring 12 until the plug rod 11 enters the interior of the slot 10, thereby fixing the plug block 7 inside the fixed block 8, thereby facilitating the quick docking installation between the first curved plate 4 and the second curved plate 5.
[0036] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
