Description

Technical Field

[0001] This utility model mainly relates to the field of mold technology, specifically a forming module device for pipe end forming connectors. Background Technology

[0002] In the processing of pipe end forming connectors, the forming process of the pipe end usually needs to be completed on specialized equipment using specific molds. Traditional mold installation methods often employ threaded connections, where the mold is directly screwed into the mold base. While this method provides a secure connection, it has significant drawbacks in actual production: First, the tightening and loosening of the threads is cumbersome and time-consuming, requiring tools and reducing mold change efficiency, thus affecting the overall production cycle. Second, after long-term use, the threads are prone to stripping, corrosion, or seizing, leading to difficult disassembly and high maintenance costs. Finally, precise alignment of the threads is required during installation, which is particularly inconvenient in operating environments with limited space or poor visibility.

[0003] Therefore, a modular device is needed that can achieve rapid assembly and disassembly while ensuring connection accuracy and rigidity. Utility Model Content

[0004] The purpose of this utility model is to provide a forming module device for forming pipe end connectors, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a forming module device for a pipe end forming connector, comprising a mold base and a mold detachably mounted thereon. A slot for inserting the mold is formed on the mold base, the slot including an arc-shaped contact surface located at the bottom center and guide slopes on both sides of the arc-shaped contact surface. An axial locking block is formed on the arc-shaped contact surface, and correspondingly, an axial locking groove is formed on the outer circumferential surface of the mold to engage with the axial locking block. A guide strip is provided on the inner wall of the slot, and a sliding groove is formed on the inward-facing end face of the mold to engage with the guide strip. A movable groove and a spring are also provided on the inner wall of the slot. The inner end of the spring is fixed to the inner side of the movable groove, and a radial locking block engaging with the movable groove is connected to the outer end of the spring. When the spring is in its natural state, the radial locking block abuts against a position on the outer circumferential surface of the mold away from the axial locking block, thereby achieving radial locking of the mold. A pull rope is fixed to the inner side of the radial locking block. A pull groove is opened on the mold base along the radial direction. The other end of the pull rope passes through the mold base along the pull groove. By pulling the pull rope outward, the spring force can be overcome, and the radial locking block can be pulled back into the movable groove, thereby releasing the locking of the mold and making it easier to take out the mold.

[0006] Preferably, the guide slope is inclined outwards, and a guide protrusion is formed on its outer end, with the inward-facing side of the guide protrusion being arc-shaped. This structure can provide initial guidance and positioning for the insertion of the mold.

[0007] Preferably, there are two guide bars symmetrically distributed in the slot to precisely guide the mold to slide radially relative to the mold seat. During the sliding process, the mold is less likely to deviate or tilt to one side under the guidance of the two symmetrical guide bars, and the radial block is located between the two guide bars.

[0008] Preferably, the radial cross-section of the radial locking block is a right-angled trapezoidal structure that flips counterclockwise along the axial direction. This structure allows the bottom of the mold to compress the inclined waist of the radial locking block during insertion, causing it to contract, and then be pushed back by a spring after passing through, thus achieving automatic locking. During removal, the right-angled waist of the radial locking block can be effectively locked, requiring a pull rope to unlock.

[0009] Preferably, a limiting tube is fixedly provided on the pull groove, and the pull rope is located inside the limiting tube. The limiting tube can protect and guide the pull rope, preventing it from wearing out and wandering.

[0010] Preferably, a bearing portion is formed on the inner side of the radial locking block, and the bearing portion is located inside the spring. The pull rope is connected and fixed to the bearing portion. A buffer block is also provided on the movable groove, and the buffer block is also located inside the spring, with an opening at its axial position to accommodate the pull rope. When the pull rope is pulled, the bearing portion contacts the buffer block. At this time, the radial locking block has fully entered the movable groove, and the buffer block plays a role in limiting movement and preventing impact.

[0011] Preferably, a handle is connected to one end of the pull rope that extends out of the mold seat, making it convenient for the operator to apply force.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The design utilizes a pull-cord mechanism to traction the radial locking block, overcoming spring force and retracting it into the movable slot. This enables rapid mold unlocking, simplifying disassembly to a single pull operation. Combined with automatic locking during insertion, this forms a complete rapid assembly / disassembly cycle, significantly improving mold change efficiency. Furthermore, the device replaces traditional threaded connections with mechanical snap-locking, fundamentally avoiding problems such as thread corrosion, stripping, or seizing. Its core locking components, such as the radial locking block and spring, are simple in structure and easy to maintain or replace, thereby improving the overall lifespan and maintainability of the module unit.

[0014] 2. Through the insertion guiding system composed of guide ramps, guide protrusions, guide strips, and grooves, and the engaging engagement of axial locking blocks and slots, the mold achieves self-centering and precise circumferential and axial positioning during installation. This structure ensures that the mold can be quickly and accurately guided to the preset working position and effectively prevents it from rotating under circumferential torque, thus guaranteeing the consistency of the pipe end forming shape. Simultaneously, the radial locking block automatically clamps the top of the mold under spring action, working in conjunction with the arc-shaped contact surface at the bottom to form a reliable radial lock, preventing the mold from loosening or falling off during processing and ensuring the rigidity and stability of the connection.

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 5 As shown, this utility model provides a forming module device for a pipe end forming connector, including a mold base 100 and a mold 200 detachably mounted thereon. The mold base 100 is typically mounted on the spindle or slider of a processing equipment via a threaded connection. A key feature of the mold base 100 is a specially designed slot. At the center of the bottom of this slot is an arc-shaped contact surface 101 that matches the bottom shape of the mold 200, used to support the mold and provide initial positioning. On both sides of the arc-shaped contact surface 101 are outwardly inclined guide slopes 102. The outermost end of each guide slope 102 is provided with an arc-shaped guide protrusion 104, used to guide the mold 200 towards the center position during initial insertion.

[0028] On the arc-shaped mating surface 101, an axial locking block 103 is protruding. On the inner wall of the slot, two guide bars 105 are symmetrically fixed. The guide bars 105 are used to guide the mold 200 towards the center position and restrict the circumferential rotation of the mold 200. At the top of the inner wall of the slot and between the two guide bars 105, a movable groove 108 is formed. A spring 111 and a radial locking block 106 are installed on the inner side of the movable groove 108. The spring 111 extends and retracts along the axial direction of the mold base 100, driving the radial locking block 106 to move axially relative to the movable groove 108. The radial locking block 106 has a cross-section that is a right-angled trapezoid with its shape turned outwards. Specifically, it has an upper base, a lower base, a right-angled leg, and a sloping leg. (The upper base is a common mathematical term that only indicates that the length of the upper base is shorter than that of the lower base, not that they are in an absolute positional relationship.) The upper and lower bases are located in the horizontal direction, with the upper base on the horizontal outward side and the lower base on the horizontal inward side. The right-angled leg and the sloping leg are located in the vertical direction, with the right-angled leg on the vertical downward side and the sloping leg on the vertical upward side. In its natural state, the spring 111 pushes the radial locking block 106 outwards, causing it to partially protrude from the movable groove 108 and contact the top of the mold 200 with the right-angled leg of the radial locking block 106, thus restricting the mold 200 from moving radially outwards and disengaging it from the mold base 100.

[0029] A tensioning part 112 is fixed to the inner side of the radial locking block 106 and connected to a pull rope 110. One end of the pull rope 110 passes through the inside of the spring 111, then through the central hole of a buffer block 113 fixed in the movable groove 108, and finally enters the limiting tube 109. The middle section of the limiting tube 109 is located in the pull groove 114 opened radially on the mold base 100. The pull rope 110 passes out from the limiting tube 109 and the end is connected to a pull handle 107.

[0030] The outer peripheral surface structure of the mold 200 fits into the slot of the mold base 100. An axial groove 201 matching the axial locking block 103 is formed inward on its outer peripheral surface. A sliding groove 202 matching the guide strip 105 is formed on its inward end face. The guide strip 105 and the sliding groove 202 work together to guide the mold 200 to be inserted into or pulled out of the mold base 100 radially.

[0031] The working principle of this product is as follows: During installation, the operator holds the mold 200 and places it into the slot of the mold base 100. The guide ramps 102 and guide protrusions 104 on both sides initially guide the mold 200 towards the center. Then, the angle of the mold 200 is adjusted so that the sliding groove 202 on it aligns with the guide strip 105 on the mold base 100. Then, under the secondary guidance of the guide strip 105, it is pushed further downward. During the insertion process, the bottom of the mold 200 will first contact the inclined waist of the radial locking block 106 and overcome the elastic force of the spring 111 to push it axially inward into the movable groove 108. When the mold 200 is fully pushed into place and the axial locking groove 201 and the axial locking block 103 are fully engaged, the radial locking block 106 will quickly pop outward under the action of the spring 111. The right-angled waist of the radial locking block 106 will press tightly against the top of the outer peripheral surface of the mold 200, thereby firmly locking the mold 200 in the mold base 100. At this time, the mold 200 is limited in the circumferential direction by the guide bar 105, in the axial direction by the axial locking block 103, and in the radial direction by the radial locking block 106, and cannot move.

[0032] When it is necessary to change the mold, the operator only needs to pull the handle 107 outward and pull the radial locking block 106 back into the movable groove 108 axially through the pull rope 110 until the bearing part 112 contacts the buffer block 113. At this time, the radial locking block 106 is completely disengaged from the mold 200, and then the mold 200 can be easily pulled out of the slot along the guide bar 105 to complete the disassembly.

[0033] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from its essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
