Description

Technical Field

[0001] This utility model relates to the field of pipe flaring mold technology, and in particular to a PVC pipe flaring forming mold. Background Technology

[0002] PVC pipes are widely used in industrial production for water supply and drainage, chemical industry, and power cable protection. The reliability of their connections directly affects the sealing performance and service life of the pipeline system. Flaring and forming, as a key process in the processing of PVC pipe connections, directly impacts the overall operating efficiency of the production line through the design and installation efficiency of its molds. Currently, most common flaring dies are fixedly connected to hydraulic cylinders via flanges and bolts. Although the structure is stable, when producing pipes of different diameters, the dies need to be changed frequently. Each change requires disassembling multiple bolts and re-aligning and installing them, which is cumbersome and time-consuming, seriously affecting the continuity and efficiency of production, especially in flexible production modes with multiple specifications and small batches. Therefore, there is an urgent need for a flaring die structure that can be quickly disassembled and easily replaced to meet the urgent needs of modern production lines for efficient and flexible production. To address this issue, we propose a PVC pipe flaring molding die. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a PVC pipe flaring molding die.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A PVC pipe flaring forming mold includes a hydraulic cylinder, a chassis, and a mold body. The chassis is installed at the bottom end of the hydraulic cylinder. The chassis is connected to a support plate through a limiting mechanism. A cover plate is fixedly installed at the bottom end of the support plate. Support bars are symmetrically installed at the bottom end of the cover plate. A top plate is inserted between the cover plate and the support bars, and the top plate is fixedly connected to the mold body.

[0005] Preferably, the front and rear surfaces of the cover plate are provided with limiting grooves, and the front and rear ends of the top plate are symmetrically provided with inner grooves. A limiting pin and a first elastic component are sequentially inserted into the inner grooves. The limiting pin is connected to the limiting groove by the elastic force of the first elastic component.

[0006] Preferably, the limiting mechanism comprises a support plate, a guide rod, a movable sleeve, a limiting block, a shaft, and a second elastic component. The top of the support plate has four sets of rectangular slots symmetrically arranged in the front, back, left, and right directions. A guide rod is fixedly installed inside the rectangular slot. A movable sleeve and a second elastic component are sleeved on the surface of the guide rod. A shaft is installed at the top of the movable sleeve, and a support plate is sleeved on the surface of the shaft. A limiting block is fixedly installed on the side wall of the support plate.

[0007] Preferably, one end of the second elastic component is fixed to the inner wall of the rectangular groove, and the other end of the second elastic component is fixed to the side wall of the movable sleeve.

[0008] Preferably, the support plate has a threaded groove from the top to the bottom, the shaft passes through the threaded groove and is connected to the movable sleeve at the bottom, and the section located inside the threaded groove has an external thread that matches its internal thread. The support plate and the shaft are connected by a threaded lifting connection.

[0009] Preferably, the top of the limiting block has a sloping surface, and the bottom of the limiting block has a flat surface.

[0010] Preferably, one end of the first elastic component is fixed to the inner groove, and the other end of the first elastic component is fixed to the limiting pin.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model replaces the traditional flange bolt fixing method by setting a quick connection mechanism consisting of a support bar, a top plate, a limit pin and a first elastic component. When changing the mold, the mold and the hydraulic cylinder can be separated and connected by a simple plug-in operation. This design is suitable for continuous production of multi-specification pipes, effectively reducing equipment downtime and improving the overall operating efficiency and flexibility of the production line.

[0012] 2. Based on the quick-installation mechanism (support bar, top plate, limit pin, first elastic component), this utility model further includes a limiting and engaging connection mechanism composed of a support plate, guide rod, movable sleeve, limit block, shaft, and second elastic component. This mechanism achieves precise adjustment of the limit block position through the support plate and shaft, thereby controlling the locking and releasing of the quick-installation mechanism and realizing rapid disassembly. This design not only greatly simplifies the process of daily maintenance and deep maintenance, reduces maintenance costs and time, but also enables key components to be replaced independently, effectively extending the service life of the mold body.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A PVC pipe flaring forming mold includes a hydraulic cylinder 1, a base plate 2, and a mold body 5. The base plate 2 is installed at the bottom end of the hydraulic cylinder 1. The base plate 2 is connected to a support plate 3 through a limiting mechanism. A cover plate 6 is fixedly installed at the bottom end of the support plate 3. Support bars 7 are symmetrically installed at the bottom end of the cover plate 6. A top plate 8 is inserted between the cover plate 6 and the support bars 7. The top plate 8 is fixedly connected to the mold body 5.

[0017] Furthermore, refer to Figure 2 It can be seen that the front and rear surfaces of the cover plate 6 are provided with limiting grooves, and the front and rear ends of the top plate 8 are symmetrically provided with inner grooves. The inner grooves are sequentially inserted with limiting pins 9 and first elastic components 10. The limiting pins 9 are connected to the limiting grooves by the elastic force of the first elastic components 10.

[0018] Furthermore, refer to Figure 2 It can be seen that the limiting mechanism consists of a support plate 4, a guide rod 11, a movable sleeve 12, a limiting block 13, a shaft 14, and a second elastic component 15. The top of the support plate 3 is symmetrically provided with four sets of rectangular slots in the front, back, left, and right directions. The guide rod 11 is fixedly installed inside the rectangular slots. The movable sleeve 12 and the second elastic component 15 are sleeved on the surface of the guide rod 11. The shaft 14 is installed at the top of the movable sleeve 12, and the support plate 4 is sleeved on the surface of the shaft 14. The limiting block 13 is fixedly installed on the side wall of the support plate 4.

[0019] Furthermore, refer to Figure 5It can be seen that one end of the second elastic component 15 is fixed to the inner wall of the rectangular groove, and the other end of the second elastic component 15 is fixed to the side wall of the movable sleeve 12. During use, the second elastic component 15 can facilitate the reset of the movable sleeve 12 through elastic action.

[0020] Furthermore, refer to Figure 1 and Figure 5 It can be seen that the support plate 4 has a threaded groove from the top to the bottom. The shaft 14 passes through the threaded groove and is connected to the movable sleeve 12 at the bottom. A section inside the threaded groove has an external thread that matches its internal thread. The support plate 4 and the shaft 14 are connected by a threaded lifting connection. The side walls of the four sets of support plates 4 abut against the outer ring wall of the chassis 2. The support plates 4 that are abutted can move up and down in a straight line, which makes it easy for the limiting block 13 to clamp and limit the chassis 2.

[0021] Furthermore, refer to Figure 6 It can be seen that the top of the limiting block 13 has a sloping surface, and the bottom of the limiting block 13 is a flat surface. During use, when the top of the limiting block 13 contacts the chassis 2, it slides to facilitate the chassis 2 to engage and install.

[0022] Furthermore, refer to Figure 3 and Figure 4 It can be seen that one end of the first elastic component 10 is fixed to the inner groove, and the other end of the first elastic component 10 is fixed to the limiting pin 9. During use, the elastic force of the first elastic component 10 can push the limiting pin 9 to be inserted into the limiting groove to achieve the limiting function.

[0023] Working principle: When using this utility model, firstly, the operator aligns and places the cover plate 6 with the limiting mechanism on the main machine through the support plate 3 connected to its top. The limiting mechanism is composed of a support plate 4, a guide rod 11, a movable sleeve 12, a shaft 14, and a second elastic component 15, which are symmetrically arranged inside the limiting mechanism to pre-fix the cover plate 6, ensuring the stability and accuracy of the mold in the initial positioning. Subsequently, the core rapid installation step is carried out by horizontally pushing the mold body 5 with the top plate 8 between the two support bars 7 symmetrically arranged at the bottom of the cover plate 6, so that the top plate 8 is accurately inserted into the insertion space formed by the support bars 7 and the bottom of the cover plate 6. During this process, the elastic pin mechanism set in the inner grooves at both ends of the top plate 8, consisting of the limiting pin 9 and the first elastic component 10, begins to play a key role: the end of the limiting pin 9 is designed with an arc-shaped slope, and when it contacts the limiting groove on the side wall of the cover plate 6, it will be compressed back into the inner groove. When the top plate 8 continues to advance until the limiting pin 9 is completely aligned with the limiting groove, the first elastic component 10 in the inner groove will instantly release its accumulated elastic potential energy, forcefully pushing the limiting pin 9 outward, so that it is firmly locked into the limiting groove. Accompanied by a clear "click", it marks the completion of the locking action and the completion of the work. The above is the complete working principle of this utility model.

[0024] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
