Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning pin technology, specifically a positioning pin installation and positioning structure for a mold. Background Technology
[0002] The locating pin of a mold is an important mechanical component used to ensure the correct alignment and positional stability of the mold during the molding process. The locating pin is usually located between the two halves of the mold to help accurately align the upper and lower molds when the mold is closed. These pins must have high precision and wear resistance because they need to withstand repeated mechanical pressure and friction during the alignment process.
[0003] During the mold movement, the existing locating pins usually move into the locating hole, which may cause the locating pins to shift. Utility Model Content
[0004] The purpose of this utility model is to provide a positioning pin installation and positioning structure for a mold, so as to solve the problem in the above-mentioned background art that the positioning pin usually moves into the positioning hole during the mold movement process, which may cause the positioning pin to deviate.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning pin mounting and positioning structure for a mold, comprising a positioning sleeve, a fixing ring, and threaded holes, wherein the fixing ring is fixedly connected to the outer top of the positioning sleeve, and multiple threaded holes are centrally symmetrically distributed inside the fixing ring; The positioning sleeve has a correction groove inside, and a correction structure is provided inside the correction groove. The correction structure has a correction sleeve, and the correction sleeve is slidably connected inside the correction groove. A first return spring is fixedly connected to the bottom of the correction sleeve, and the bottom of the first return spring is fixedly connected to the inside of the correction groove.
[0006] Preferably, the positioning sleeve has a positioning sliding hole inside, and the positioning sliding hole is located inside the correction sliding groove inside the positioning sleeve, and a top block is slidably connected inside the positioning sliding hole.
[0007] Preferably, a second return spring is fixedly connected to the bottom of the positioning sliding hole, and the top of the second return spring is fixedly connected to the top block. The top block has a slot inside, and the second return spring is located inside the slot inside the top block.
[0008] Preferably, a positioning pin is fixedly connected to the upper end of the positioning sliding hole, and the lower end of the positioning pin is in contact with the top of the top block.
[0009] Preferably, a connecting plate is fixedly connected to the top of the positioning pin, and the bottom of the connecting plate is in contact with the top of the corrective sleeve, and the positioning pin is located inside the corrective sleeve.
[0010] Preferably, the positioning sleeve is installed on the fixed part of the mold, and the connecting plate is installed on the moving part of the mold.
[0011] Compared with the prior art, the beneficial effects of this utility model are: The positioning pin installation and positioning structure of this mold is equipped with a correction structure. During the process of the positioning pin moving into the positioning sliding hole, the positioning pin will first pass through the inside of the positioning pin. The bottom of the positioning pin is provided with a slope. When the positioning sleeve moves into the correction sleeve and causes a displacement, the slope at the bottom of the positioning pin will come into contact with the correction sleeve, so that the slope of the positioning pin slides inside the correction sleeve, thereby correcting the direction of the positioning pin. Furthermore, after the positioning pin is corrected, the positioning pin will continue to slide into the positioning slide hole. At this time, the connecting plate will be driven by the positioning pin to move downward. At the same time, the connecting plate will drive the correction sleeve to slide downward inside the correction slide groove. Meanwhile, the correction sleeve will compress the first reset spring until the top of the correction sleeve is flush with the top of the positioning sleeve. Furthermore, after the top of the positioning pin drives the straightening sleeve to be flush with the top of the positioning sleeve, the positioning pin will continue to slide inside the positioning slide hole. At this time, the positioning pin drives the top block to slide inside the positioning slide hole, and at the same time, the top block compresses the second reset spring until the connecting plate and the top of the positioning sleeve are in contact.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] In a further preferred embodiment of this utility model, such as Figure 1 - Figure 4 As shown, a positioning pin mounting and positioning structure for a mold includes a positioning sleeve 1, a fixing ring 2, and threaded holes 3. The fixing ring 2 is fixedly connected to the outer top of the positioning sleeve 1, and multiple threaded holes 3 are centrally symmetrically distributed inside the fixing ring 2. The positioning sleeve 1 has a straightening groove 4 inside, and a straightening structure is provided inside the straightening groove 4. The straightening structure has a straightening sleeve 5, and the straightening sleeve 5 is slidably connected inside the straightening groove 4. A first return spring 6 is fixedly connected to the bottom of the straightening sleeve 5, and the bottom of the first return spring 6 is fixedly connected inside the straightening groove 4. The positioning sleeve 1 has a positioning sliding hole 7 inside, and the positioning sliding hole 7 is located inside the positioning sleeve 1 at the straightening groove 4. Inside the slide groove 4, a top block 8 is slidably connected inside the positioning slide hole 7. A second return spring 9 is fixedly connected to the bottom of the positioning slide hole 7, and the top of the second return spring 9 is fixedly connected to the top block 8. The top block 8 has a slot inside, and the second return spring 9 is located inside the slot. A positioning pin 10 is fixedly connected to the upper end inside the positioning slide hole 7, and the lower end of the positioning pin 10 is in contact with the top of the top block 8. A connecting plate 11 is fixedly connected to the top of the positioning pin 10, and the bottom of the connecting plate 11 is in contact with the top of the straightening sleeve 5. The positioning pin 10 is located inside the straightening sleeve 5. The positioning sleeve 1 is installed on the fixed part of the mold, and the connecting plate 11 is installed on the moving part of the mold. During the process of the positioning pin 10 moving into the positioning sliding hole 7, the positioning pin 10 will first pass through the inside of the positioning pin 10. The bottom of the positioning pin 10 is provided with a slope.
