Description

Technical Field

[0001] This utility model relates to the field of hot runner manifolds, and more particularly to a mold hot runner manifold that is easy to install. Background Technology

[0002] In the field of plastic injection molding, hot runner systems are widely used due to their advantages such as effectively shortening the molding cycle, reducing waste, and improving product quality. The manifold, as one of the core components of the hot runner system, primarily functions to evenly distribute the molten plastic from the injection molding machine to each cavity or hot runner nozzle. The manifold is typically composed of two plates (upper and lower manifolds), internally machined with complex hot runner channels and integrated with heating wires for precise temperature control.

[0003] During use, hot runner systems are prone to accumulating residues such as hot melt adhesive and plastic particles. Most existing manifolds are fixed by welding. While this method ensures the stability of the manifold structure, it makes it impossible to disassemble when cleaning or maintenance is required, making cleaning difficult. Utility Model Content

[0004] To overcome the shortcomings of existing manifolds, which are mostly fixed by welding and cannot be quickly disassembled and installed, this utility model provides a mold base hot runner manifold that is easy to install.

[0005] The technical solution of this utility model is as follows: a hot runner manifold plate for easy installation, comprising a lower manifold plate, an upper manifold plate, a sprue tube, a hot runner, a heating wire, fixing bolts, and a folding rod. The lower manifold plate has multiple threaded holes, and the upper manifold plate has multiple fixing holes. The fixing bolts are threadedly connected to the lower manifold plate through the threaded holes and slidably connected to the upper manifold plate through the fixing holes. The fixing bolts fix the lower manifold plate and the upper manifold plate together through the threaded holes and the fixing holes. A folding rod is rotatably provided on the top of the fixing bolts. The upper manifold plate is provided with a sprue tube, the lower manifold plate has a hot runner, and the lower manifold plate is provided with a heating wire.

[0006] In a preferred embodiment of the present invention, a positioning block is also included. A plurality of positioning blocks are provided on the lower diverter plate, and a positioning groove adapted to the positioning block is provided on the upper diverter plate.

[0007] In a preferred embodiment of the present invention, it further includes elastic buckles. Multiple elastic buckles are provided on the lower distributor plate, and the elastic buckles fix the heating wire to the lower distributor plate by snapping.

[0008] In a preferred embodiment of the present invention, a permanent magnet and an iron sheet are also included. The top of the fixing bolt is provided with a permanent magnet, and the folding rod is provided with an iron sheet that cooperates with the permanent magnet.

[0009] In a preferred embodiment of the present invention, anti-slip stripes are also included, with one end of the folding rod having anti-slip stripes.

[0010] In a preferred embodiment of this utility model, both the lower and upper splitter plates are provided with mounting grooves.

[0011] In a preferred embodiment of this utility model, a damping block is provided at the connection between the folding rod and the fixing bolt.

[0012] In a preferred embodiment of this utility model, the top of the fixing bolt has a groove, and the folding rod can be completely stored in the groove.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model achieves the fixation of the lower and upper diverter plates by using the cooperation of fixing bolts, threaded holes and fixing holes. The top of the fixing bolt is equipped with a folding rod that can be rotated. During installation, the folding rod can be rotated and unfolded to act as a lever to assist in tightening the fixing bolt. During disassembly, the folding rod can also be unfolded and the fixing bolt rotated in the opposite direction to quickly loosen the fixing bolt and separate the upper and lower diverter plates, which greatly improves the efficiency of installation and disassembly and facilitates cleaning or maintenance by operators.

[0014] 2. Through the design of positioning blocks and positioning grooves, this utility model can quickly and accurately position the upper and lower diverter plates during installation, ensuring that the threaded holes and fixing holes are aligned, reducing installation errors and improving installation accuracy.

[0015] 3. This utility model uses elastic buckles on the lower distributor plate to fix the heating wire to the lower distributor plate by snapping, which can prevent the heating wire from shifting during installation or use, and ensure the stability and safety of the heating system.

[0016] 4. This utility model effectively prevents the fixing bolts from loosening due to vibration or external force during handling or operation through the synergistic effect of the damping block and the magnetic structure. At the same time, the hidden design of the folding rod avoids safety hazards caused by hooking. Attached Figure Description

Detailed Implementation

[0023] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0024] An easy-to-install hot runner manifold for mold blanks, such as Figures 1-5 As shown, it includes a lower flow divider 1, an upper flow divider 2, a filling pipe 3, a hot runner 4, a heating wire 5, a fixing bolt 6, and a folding rod 7. The lower flow divider 1 has multiple threaded holes 101, and the upper flow divider 2 has multiple fixing holes 201. The fixing bolt 6 is threaded to the lower flow divider 1 through the threaded holes 101, and slidably connected to the upper flow divider 2 through the fixing holes 201. The fixing bolt 6 fixes the lower flow divider 1 and the upper flow divider 2 together through the threaded holes 101 and the fixing holes 201. The top of the fixing bolt 6 is rotatably equipped with a folding rod 7. The upper flow divider 2 is equipped with a filling pipe 3, the lower flow divider 1 has a hot runner 4, and the lower flow divider 1 is equipped with a heating wire 5.

[0025] During installation, the fixing bolt 6 passes through the fixing hole 201 (sliding connection) of the upper diverter plate 2 and the threaded hole 101 (threaded connection) of the lower diverter plate 1. The two plates are pressed together and fixed by tightening the fixing bolt 6. During operation, the folding rod 7 can be rotated out as a lever to assist in tightening the fixing bolt 6. After installation, the folding rod 7 is reset to save space and prevent the fixing bolt 6 from being accidentally touched and loosened. Similarly, during disassembly, the folding rod 7 can be unfolded as a lever to rotate the fixing bolt 6 in the opposite direction, which can quickly loosen the fixing bolt 6 and separate the upper diverter plate 2 and the lower diverter plate 1.

[0026] like Figures 1-2 As shown, it also includes positioning blocks 8. The lower diverter plate 1 is provided with multiple positioning blocks 8, and the upper diverter plate 2 has positioning grooves that are adapted to the positioning blocks 8. The positioning blocks 8 and the positioning grooves can quickly and accurately position the upper and lower diverter plates 1 during installation, ensuring that the threaded holes 101 and the fixing holes 201 are aligned, thereby improving installation efficiency and accuracy.

[0027] like Figures 1-3 As shown, it also includes elastic clips 9. Multiple elastic clips 9 are provided on the lower distributor plate 1, and the elastic clips 9 fix the heating wire 5 to the lower distributor plate 1 by snapping. This prevents the heating wire 5 from shifting during installation or use, ensuring the stability and safety of the heating system.

[0028] like Figure 5 As shown, it also includes a permanent magnet 10 and an iron plate 11. The top of the fixing bolt 6 is provided with a permanent magnet 10, and the folding rod 7 is provided with an iron plate 11 that cooperates with the permanent magnet 10. The permanent magnet 10 on the top of the fixing bolt 6 and the iron plate 11 on the folding rod 7 are magnetically attracted and cooperated, so that the folding rod 7 can be quickly attracted and fixed in the non-working state, avoiding accidental loosening or falling off of the folding rod 7 and improving the convenience of operation.

[0029] like Figure 5 As shown, it also includes anti-slip stripes 12, with one end of the folding rod 7 having anti-slip stripes 12. The anti-slip stripes 12 increase the friction during operation, making it easier for the operator to rotate the folding rod 7.

[0030] Both the lower distributor plate 1 and the upper distributor plate 2 are provided with mounting grooves 13. The mounting grooves 13 provide a clear installation position for the heating wire 5. After the heating wire 5 is placed in the mounting groove 13, the side wall of the mounting groove 13 can restrict the heating wire 5 to a certain extent and prevent the heating wire 5 from moving at will during the installation process.

[0031] A damping block is provided at the connection between the folding rod 7 and the fixing bolt 6. The damping block provides resistance to the rotation of the folding rod 7, preventing it from rotating arbitrarily and facilitating stability at the required position for easy operation.

[0032] The top of the fixing bolt 6 has a groove, into which the folding rod 7 can be completely stored. This prevents the folding rod 7 from accidentally snagging or colliding during handling or operation of the mold, which could cause the fixing bolt 6 to loosen.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
