Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of back cover tube production, specifically a back cover tube forming mold. Background Technology
[0002] Back cover fittings are key components in piping systems that provide protection, sealing, or connection functions, and are widely used in water supply and drainage, automotive air conditioning, energy transmission, and other fields.
[0003] When producing back cover tubing, existing traditional molds have a relatively fixed structure. When producing back cover tubing of different specifications, the entire mold often needs to be replaced, which not only increases production costs but also prolongs production preparation time. At the same time, the forming mechanism of some molds is difficult to precisely control the displacement and movement trajectory of each part of the mold during the tubing forming process, resulting in large dimensional errors in the tubing and easy to produce scrap. In addition, some molds lack effective buffering and reset mechanisms, which reduces production efficiency and economic benefits. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that the lack of an effective buffer and reset mechanism reduces production efficiency and economic benefits, and to propose a back cover tube forming mold.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a back cover tube forming mold, comprising a positioning plate and a pad, wherein the positioning plate is threadedly connected to the pad by bolts, the surface of the pad is inserted into the lower template, an adjusting plate is installed on the surface of the lower template, the upper end of the adjusting plate is movably connected to the upper template, and a reciprocating mechanism is connected to the upper end of the upper template.
[0006] This feature—the stable connection between the positioning plate and the pad—provides a solid foundation for the entire mold structure, ensuring that the mold will not shake or shift during the pipe forming process. The plug-in design between the lower template and the pad not only facilitates installation and disassembly but also allows for quick replacement of lower templates of different specifications to meet the production needs of various back cover pipe fittings.
[0007] Preferably, the reciprocating mechanism includes a connecting block, the lower end of which is threadedly connected to the upper template, the outer wall of which is fixedly connected to a tension spring, and the end of which is fixedly connected to a fixed seat.
[0008] This feature: The threaded connection between the connecting block and the upper template ensures the stability between the two, enabling the reciprocating mechanism to stably drive the upper template during operation. The tension spring, as the core elastic component, is fixed at both ends to the connecting block and the fixed seat respectively. When an external driving force is applied to the upper template, the tension spring will undergo elastic deformation. After the driving force is removed, it can quickly pull the upper template back to its original position by relying on its own elastic restoring force, thereby realizing the reciprocating motion of the upper template and effectively improving the continuity of the back cover tube forming.
[0009] Preferably, the fixing seat is threadedly connected to the positioning plate by bolts, and the outer wall of the upper template is connected to a displacement mechanism.
[0010] This setting: The bolt connection between the fixed seat and the positioning plate can stably fix the reciprocating mechanism to the positioning plate, providing a reliable support foundation for the reciprocating motion of the upper template and avoiding shaking or displacement of the mechanism due to unstable fixing during the movement.
[0011] Preferably, the displacement mechanism includes a punch and a die, the lower end of which is slidably connected to the upper template, the end of which is inserted into a slider, and the inner wall of the slider is machined with a slope hole.
[0012] This feature: The sliding connection between the punch and the upper template allows the punch to move smoothly on the surface of the upper template, facilitating position adjustments according to the forming requirements of the back cover tube. The insertion fit between the slider and the punch ensures a tight connection, guaranteeing that the slider moves synchronously with the punch during its movement. The beveled holes machined on the inner wall of the slider provide a structural basis for subsequent mating with the wedge.
[0013] Preferably, the inner wall of the slope hole is movably connected to the wedge.
[0014] This setting: The movable connection between the inner wall of the slope hole and the wedge can convert the vertical movement of the wedge into the horizontal displacement of the slider.
[0015] Preferably, the upper end of the wedge is fixedly connected to the outer block.
[0016] This feature allows the external block to connect to an external drive device. The external block will synchronously drive the wedge to move in the vertical direction. Through the cooperation of the wedge and the slope hole, precise control of the horizontal displacement of the slider can be achieved, providing stable power transmission for the forming of the back cover tube.
[0017] Preferably, the surface of the upper template is movably connected to the pipe fitting.
[0018] This setting: The surface of the upper template provides a stable placement space for the pipe fitting. During the forming process, the pipe fitting can fit tightly against the surface of the upper template, ensuring that the pipe fitting can be accurately formed according to the preset shape and size under the action of the die and related mechanism.
[0019] The present invention provides a back cover tube forming mold with the following advantages: A stable foundation is established by bolting the positioning plate and the pad, preventing shaking during forming and ensuring accuracy. The lower template is inserted into the pad for easy replacement and high flexibility. In the reciprocating mechanism, the connecting block is connected to the upper template, and the tension spring connects the connecting block to the fixed seat, enabling the upper template to reciprocate, improving forming continuity and efficiency. In the displacement mechanism, the convex and concave molds slide on the upper template, and the slider inserts into the convex and concave molds. The inclined fitting of the slider's slope hole allows for precise control of displacement, ensuring accurate forming of the tube and improving overall yield and convenience.

[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] Please see Figure 1-8 In this embodiment, a back cover tube forming mold includes a positioning plate 1 and a pad 2. The positioning plate 1 is threadedly connected to the pad 2 by bolts. The surface of the pad 2 is inserted into the lower template 3. An adjusting plate 4 is installed on the surface of the lower template 3. The upper end of the adjusting plate 4 is movably connected to the upper template 5. A reciprocating mechanism 6 is connected to the upper end of the upper template 5.
[0031] The reciprocating mechanism 6 includes a connecting block 601. When the upper template 5 is moved by an external driving force, the tension spring 602 elastically deforms, the driving force is removed, and the tension spring 602 pulls the upper template 5 back to its original position by means of elastic restoring force, thereby realizing the reciprocating motion of the upper template 5. The lower end of the connecting block 601 is threadedly connected to the upper template 5, the outer wall of the connecting block 601 is fixedly connected to the tension spring 602, and the end of the tension spring 602 is fixedly connected to the fixed seat 603.
[0032] Positioning plate 1 and pad 2 are bolted together to lay a stable foundation, prevent shaking during molding, and ensure accuracy. Lower template 3 is inserted into pad 2 for easy replacement and high flexibility. In reciprocating mechanism 6, connecting block 601 is connected to upper template 5, and tension spring 602 connects connecting block 601 and fixed seat 603, enabling reciprocating motion of upper template 5 and improving molding continuity and efficiency. In displacement mechanism 7, punch 701 slides onto upper template 5, slider 702 inserts into punch 701, and wedge 8 matches the slope hole 703 of slider 702, which can precisely control displacement, ensuring accurate molding of pipe 10 and improving overall yield and convenience.
[0033] The fixed base 603 is threadedly connected to the positioning plate 1 by bolts. The outer wall of the upper template 5 is connected to the displacement mechanism 7, which includes a punch and a die 701. The lower end of the punch and a die 701 is slidably connected to the upper template 5, so that the punch and a die 701 can move smoothly on the surface of the upper template 5, which is convenient to adjust the position according to the forming requirements of the back cover tube 10. The lower end of the punch and a die 701 is slidably connected to the upper template 5, and the end of the punch and a die 701 is inserted into the slider 702. The inner wall of the slider 702 is machined with a slope hole 703.
[0034] The inner wall of the slope hole 703 is movably connected to the wedge 8. The upper end of the wedge 8 is fixedly connected to the outer block 9. After the outer block 9 is connected to the external drive device, the drive device drives the outer block 9 to move vertically with the wedge 8. The surface of the upper template 5 is movably connected to the pipe fitting 10.
[0035] Working principle:
[0036] Assembly process
[0037] Foundation Fixing: First, use bolts to thread the positioning plate 1 and the pad 2 together to build a stable base for the mold, ensuring that the overall structure does not wobble during subsequent assembly and molding. Next, insert the lower template 3 onto the surface of the pad 2. This insertion design facilitates the replacement of lower templates of different specifications to adapt to diverse production needs. Then, install the adjustment plate 4 on the surface of the lower template 3.
[0038] Core Mechanism Assembly: Connect the upper template 5 to the upper end of the adjusting plate 4 to complete the construction of the upper and lower basic structures of the mold. For the reciprocating mechanism 6, first connect the lower end of the connecting block 601 to the upper template 5 with a thread, then fix one end of the tension spring 602 to the outer wall of the connecting block 601 and the other end to the fixed seat 603. Finally, use bolts to thread the fixed seat 603 to the positioning plate 1 to stably mount the reciprocating mechanism on the positioning plate 1. When assembling the displacement mechanism 7, first slide the lower end of the punch and concave mold 701 to the upper template 5, then insert the end of the punch and concave mold 701 into the slider 702 to ensure a tight fit. Finally, connect the wedge 8 movably into the slope hole 703 on the inner wall of the slider 702 and fix the outer block 9 to the upper end of the wedge 8 to complete the entire mold assembly.
[0039] Work process
[0040] After the external block 9 is connected to the external drive device, the drive device drives the external block 9 to move vertically with the wedge 8. The wedge 8 moves within the slope hole 703 of the slider 702, converting the vertical motion into the horizontal displacement of the slider 702. The slider 702 drives the punch and die 701 to slide on the surface of the upper template 5. At the same time, the tension spring 602 of the reciprocating mechanism 6 cooperates. When the external driving force moves the upper template 5, the tension spring 602 elastically deforms, the driving force is removed, and the tension spring 602 pulls the upper template 5 back to its original position by its elastic restoring force, realizing the reciprocating motion of the upper template 5. During this process, the tube 10 placed on the surface of the upper template 5, under the action of the punch and die 701, the upper template 5 forms a certain downward pressure on the tube 10, and applies external force to the tube 10 before and after between the upper template 5 and the lower template 3, so that the tube 10 is accurately formed according to the preset shape and size.
[0041] Usage effect
[0042] The stable connection between the positioning plate 1 and the pad 2, and the reliable fixing of the fixed seat 603, prevent the mold from shaking and shifting during operation, ensuring molding accuracy. The insertion of the lower template 3 and the pad 2 facilitates the replacement of the lower template. The sliding connection between the punch and die 701 and the upper template 5 facilitates the adjustment of the position to adapt to different molding requirements. The reciprocating mechanism 6 realizes the reciprocating motion of the upper template 5, improves molding continuity, and increases production efficiency. The wedge 8 and the slope hole 703 cooperate to precisely control the displacement of the slider 702, ensuring that the pipe fitting 10 is accurately molded and meets the high-quality requirements of pipe fittings in fields such as water supply and drainage, and automotive air conditioning.
