Description

Technical Field

[0001] This utility model relates to the field of demolding technology, and in particular to a mold tube extraction device. Background Technology

[0002] During the processing of epoxy tubes, a mold and a mold tube inside the mold are used to form a mold cavity. After the epoxy resin melts, it is pressed into the mold cavity, cooled and solidified, and then removed from the mold cavity. However, after the epoxy tube is solidified, the connection between it and the mold tube is quite strong, making it difficult to pull out and resulting in low efficiency. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a mold tube extraction device that can simultaneously extract multiple mold tubes from epoxy tubes, offering high efficiency and safety.

[0004] This utility model discloses a mold tube extraction device, including a base, a vertically upward baffle provided in the middle of the base along its length, a plurality of limiting holes arranged on the baffle along the width of the base, a first slide rail and a second slide rail respectively provided on the base on both sides of the baffle, both the first slide rail and the second slide rail being arranged along the length of the base, a movable disk provided on the first slide rail, two support brackets provided at intervals on the movable disk, the support brackets being provided with corresponding arc-shaped concave structures, the arc-shaped concave structures being used to place tubular products, the mold tubes inside the tubular products on the arc-shaped concave structures corresponding to the limiting holes; a sliding frame provided on the second slide rail, the sliding frame being provided with tube extractors corresponding one-to-one with the limiting holes, a hydraulic cylinder provided at the end of the base where the second slide rail is located, the telescopic rod of the hydraulic cylinder being fixedly connected to the sliding frame; the tube extractors being connected to the end of the mold tube; the diameter of the limiting hole is smaller than the outer diameter of the tubular product, but greater than or equal to the outer diameter of the mold tube.

[0010] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0011] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0012] Example 1:

[0013] like Figure 1 As shown, this utility model discloses a mold tube extraction device, including a base 1. A vertically upward baffle 2 is provided at the middle of the base 1 along its length. A plurality of limiting holes 8 are arranged on the baffle 2 along the width of the base 1. A first slide rail 3 and a second slide rail 9 are respectively provided on the base 1 on both sides of the baffle 2. The first slide rail 3 and the second slide rail 9 are both arranged along the length of the base 1. A movable disk 4 is provided on the first slide rail 3. Two support brackets 5 are arranged at intervals on the movable disk 4. The support brackets 5 are provided with corresponding arc-shaped concave joints. Structure 6, the arc-shaped concave structure 6 is used to place tubular products, the mold tube 17 inside the tubular product on the arc-shaped concave structure 6 corresponds to the limiting hole 8; a sliding frame 10 is provided on the second slide rail 9, and a tube puller corresponding to the limiting hole 8 is provided on the sliding frame 10; a hydraulic cylinder 11 is provided at the end of the base 1 where the second slide rail 9 is located, and the telescopic rod of the hydraulic cylinder 11 is fixedly connected to the sliding frame 10; the tube puller is connected to the end of the mold tube 17; the diameter of the limiting hole 8 is smaller than the outer diameter of the tubular product, and greater than or equal to the outer diameter of the mold tube 17.

[0014] The tubular product can be an epoxy tube 16. The base 1 is fixed to the ground. The epoxy tube 16 to be removed is placed on the support bracket 5 of the moving disk 4, with both ends of the same epoxy tube 16 located in corresponding arc-shaped concave structures 6 on the support brackets 5 at both ends of the moving disk 4. This ensures that the axial direction of the epoxy tube 16 is aligned with the length direction of the first slide rail 3. In this embodiment, the baffle 2 has four limiting holes 8, and the support bracket 5 also has four arc-shaped concave structures 6, which correspond one-to-one. After placing the epoxy tube 16 on the support bracket 5, the moving disk 4 is pushed to insert the mold tube 17 at the end of the epoxy tube 16 into the limiting hole 8 of the baffle 2. Because the diameter of the limiting hole 8 on the baffle 2 is smaller than the outer diameter of the epoxy tube 16, the epoxy tube 16 cannot pass through. However, the diameter of the limiting hole 8 is larger than the mold tube 17, so the mold tube 17 can pass through. Then the hydraulic cylinder 11 extends, pushing the sliding frame 10 close to the baffle 2. The tube puller on the sliding frame 10 connects with the end of the mold tube 17. Then the hydraulic cylinder 11 retracts, and the tube puller on the sliding frame 10 carries the mold tube 17 away from the baffle 2, while the epoxy tube 16 is restricted by the baffle 2. In this way, the mold tube 17 inside the epoxy tube 16 can be pulled out. The operation is simple, convenient and efficient, and the process is safe and reliable.

[0015] The tube puller is a circular tube 12 with a connecting pin hole 13. The connecting pin hole 13 extends radially through the circular tube 12. The diameter of the end of the mold tube 17 is smaller than the inner diameter of the circular tube 12, and a connecting pin hole 13 is also provided at the end of the mold tube 17. This connecting pin hole 13 extends radially through the mold tube 17. When the end of the mold tube 17 is inserted into the circular tube 12, the two connecting pin holes 13 align. The tube puller is a circular tube 12 fixed on the sliding frame 10. The end of the mold tube 17 can be inserted into the inside of the circular tube 12, and the two connecting pin holes 13 correspond to each other. Inserting the pin shaft achieves the connection between the circular tube 12 and the mold tube 17, which is simple and convenient. Of course, in the actual connection process, it is necessary to rotate the epoxy tube 16 so that the connecting pin hole 13 on the mold tube 17 corresponds to the connecting pin hole 13 on the circular tube 12. Alternatively, a rotatable connection can be used between the round tube 12 and the sliding frame 10. The round tube 12 can rotate relative to the sliding frame 10, but its axial position will not change. In this way, during actual operation, since the overall weight of the epoxy tube 16 and the mold tube 17 is relatively large, when the mold tube 17 is connected to the round tube 12, it is not necessary to rotate the epoxy tube 16; only the round tube 12 needs to be rotated, making the operation simpler and more efficient.

[0016] Connecting seats 7 are provided on the bases 1 at both ends of the baffle 2. Vertically downward slots are provided on the connecting seats 7, and the baffle 2 is inserted into the slots. Since the diameters of the epoxy tubes 16 vary, the baffle 2 is used in an insert-type configuration to allow the equipment to accommodate the extraction of the mold tube 17 from epoxy tubes 16 of different diameters. Different baffles 2 with different limiting holes 8 can be replaced according to actual needs. Of course, because the center height of the mold tube 17 changes after the diameter of the epoxy tube 16 is placed on the support bracket 5, the support bracket 5 can be replaced, or an arc-shaped pad can be placed inside the arc-shaped concave structure 6 of the support bracket 5 to adjust the center height of the mold tube 17 so that it can connect with the round tube 12.

[0017] A lifting connection hole 14 is provided at the top of the baffle 2. Because the baffle 2 must obstruct the movement of the epoxy tube 16 during the removal of the mold tube 17, the baffle 2 will bear a significant thrust. To ensure the stability of the baffle 2, a thicker baffle 2 can be used, resulting in a relatively large overall weight. For easy replacement, the lifting connection hole 14 at the top of the baffle 2 allows for safe and reliable replacement using a crane.

[0018] A rubber roller 15 with an upward protrusion is provided on the base 1 between the second slide rail 9 and the baffle 2, and the highest point of the rubber roller 15 is aligned with the limiting hole 8.

[0019] Since the mold tube 17 will move out of the limiting hole 8 after being pulled out of the epoxy tube 16, it is supported by the rubber roller 15 to ensure the stability of the mold tube 17.
