Description

Technical Field

[0001] The utility model relates to the technical field of hot runner manifolds, in particular to a manifold device. Background Art

[0002] Hot runner manifolds can be divided into two types according to the different heating methods: internal heating and external heating. In internal heating manifolds, the flow channel is mainly heated by heat conduction from the heater. In external heating manifolds, heating holes are opened in the direction parallel to the flow channel, and heating rods or heating coils are inserted inside to heat the flow channel from the outside. Among them, electric heating wires are commonly used heating structures for manifolds.

[0003] For example, the Chinese invention patent application with the announcement number CN112277264A discloses a hot runner manifold assembly and a hot runner system, including an upper manifold, a lower manifold, a fixing bolt, an adjusting bolt, a hot nozzle and a material flow channel, the number of the fixing bolts is four, the number of the adjusting bolts, the hot nozzle and the material flow channel is two, a feeding structure is arranged in the middle of the top of the upper manifold, the feeding structure is composed of a feeding pipe, a connecting cover and a plurality of connecting holes, a temperature control structure is arranged between the lower manifold and the upper manifold, the temperature control structure is composed of a card slot, an electric heater, a protective plate, a ceramic heat insulation plate, a controller and a temperature sensor. The present invention can detect the temperature of the material in the material flow channel and transmit the data to the controller by setting a temperature sensor, if the detected temperature is low, the controller controls the electric heater to start and heat the material in the material flow channel through the upper manifold, if the detected temperature is high, the controller controls the electric heater to stop heating.

[0004] The electric heater is fixed on the manifold by a protective plate. In this structure, once the electric heater is damaged, the staff needs to use tools to pry up the protective plate to replace the electric heater. In the process of prying up the protective plate, the manifold itself is likely to be damaged, and the protective plate may also break, causing economic losses. At the same time, the prying and disassembly method of the protective plate is difficult. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0031] A manifold device includes a manifold body 1 and a heating wire 2, wherein the heating wire 2 can convert electrical energy into thermal energy to heat the manifold body 1. This is a prior art and will not be described in detail herein.

[0032] The improvements of the present invention over the prior art are as follows: First, Figure 2 As shown, the heating wire 2 is pluggably embedded in the heating wire groove opened on the manifold body 1. Specifically, the heating wire 2 can be easily inserted into the heating wire groove. Similarly, the heating wire 2 can also be easily taken out from the heating wire groove. In order to achieve efficient heat conduction between the heating wire 2 and the inner wall of the heating wire groove, a thermal conductive silicone grease layer can be set between the heating wire 2 and the inner wall of the heating wire groove.

[0033] Secondly, if Figure 1-Figure 5 As shown, a pressure plate 3 is detachably fixedly installed on the plate surface of the manifold body 1 on which the heating wire 2 is provided. The material of the pressure plate 3 is not specifically limited here. For example, the same material as that of the manifold body 1 can be used. A groove 31 arranged along the extension direction of the heating wire 2 is provided on one side surface of the pressure plate 3 that is close to the heating wire 2; further, a plurality of clamping members 4 for pressing against the heating wire 2 are provided on the pressure plate 3. The clamping members 4 include a threaded rod 41 threadedly connected to the pressure plate 3. The axial direction of the threaded rod 41 is perpendicular to the plate surface of the pressure plate 3, and the threaded rod 41 passes through the pressure plate 3; one end of the threaded rod 41 extends to the inside of the groove 31, and tightening the threaded rod 41 can press the heating wire 2 against the heating wire groove.

[0034] When the above scheme is actually used, the heating wire 2 converts electrical energy into thermal energy after being energized and transmits it to the manifold body 1, thereby heating the manifold body 1 and maintaining the manifold body 1 at a suitable temperature; and in this process, if the heating wire 2 is damaged and needs to be replaced, the pressing plate 3 is directly removed, and then the damaged heating wire 2 is taken out from the heating wire groove and a new heating wire 2 is installed in the heating wire groove, and then the pressing plate 3 is reinstalled and fixed, and after completion, the threaded rod 41 is rotated to gradually reduce the distance between one end face of the threaded rod 41 and the pressing plate 3, so that the threaded rod 41 can be used to firmly press the heating wire 2 in the heating wire groove to prevent the heating wire 2 from being displaced or arched.

[0035] The above scheme first changes the matching relationship between the heating wire 2 and the heating wire groove, so that the heating wire 2 can be easily taken out of the heating wire groove or the heating wire 2 can be easily plugged into the heating wire groove, and then the detachable pressing plate 3 is matched with the threaded rod 41, and the heating wire 2 is pressed and fixed by tightening the threaded rod 41 to prevent the heating wire 2 from being displaced or arched, etc., which not only realizes the low-difficulty replacement of the heating wire 2, but also ensures the heating effect of the heating wire 2 on the manifold body 1, and at the same time will not cause damage to the manifold body 1.

[0036] like Figure 3 and Figure 4As shown, one end of the threaded rod 41 is rotatably connected to a pressure cap 42, the diameter of the pressure cap 42 is larger than the groove width of the heating wire groove, and the pressure cap 42 and the threaded rod 41 are connected in a rotating manner. For example, there is a certain friction force between the pressure cap 42 and the threaded rod 41, and this friction force can keep the pressure cap 42 connected to the bottom of the threaded rod 41 without falling off, and when the pressure cap 42 is pressed against the surface of the heating wire 2, the friction force will not affect the relative rotation between the threaded rod 41 and the pressure cap 42. Among them, the pressing cap 42 is a cylindrical shape with a closed bottom, and the diameter of the threaded rod 41 is smaller than the inner diameter of the pressing cap 42. In actual use, during the process of tightening the threaded rod 41, after the pressing cap 42 and the surface of the heating wire 2 come into contact, due to the friction between the pressing cap 42 and the surface diameter of the heating wire 2, the pressing cap 42 can remain stationary during the rotation of the threaded rod 41. At the same time, since the diameter of the pressing cap 42 is larger than the groove width of the heating wire groove, the heating wire 2 is protected and the pressing cap 42 is prevented from crushing the heating wire 2.

[0037] like Figure 3 As shown, the other end of the threaded rod 41 is fixedly connected with a coaxially arranged inner hexagonal cap 43, and the inner hexagonal cap 43 is cylindrical. The arrangement of the inner hexagonal cap 43 can facilitate the staff to use a suitable hexagonal tool to rotate the threaded rod 41.

[0038] In this embodiment, Figure 1-Figure 5 As shown, in order to prevent the threaded rod 41 from loosening, a locking member 5 is provided on one side of each threaded rod 41 , and the locking member 5 can tighten the threaded rod 41 in one direction.

[0039] like Figure 3-Figure 5 As shown, the anti-loosening member 5 includes a side rod 51 arranged on the pressure plate 3, a ratchet 54 fixedly connected to the side rod 51 through a spring sheet 52, and a plurality of ratchet grooves 53 opened on the outer peripheral surface of the hexagonal cap 43; the ratchet 54 is clamped in the ratchet groove 53 through the spring sheet 52.

[0040] In this way, due to the setting of the ratchet groove 53 and the ratchet tooth 54, and the ratchet tooth 54 is clamped in the ratchet groove 53 through the spring sheet 52, the threaded rod 41 can only rotate in the tightening direction. After the threaded rod 41 is tightened, the limiting effect of the ratchet tooth 54 can effectively prevent the threaded rod 41 from loosening.

[0041] Afterwards, in order to facilitate the loosening of the threaded rod 41, the installation method of the side rod 51 is limited in this embodiment, such as Figure 3-Figure 5As shown, the length direction of the side rod 51 is parallel to the axial direction of the threaded rod 41, and the side rod 51 slides through the pressure plate 3; one end of the side rod 51 extends to the inside of the groove 31 and is fixed with a second magnet 56, and the other end of the side rod 51 is fixed with a first magnet 55; the side rod 51 has a locking position in which the first magnet 55 is magnetically connected to the pressure plate 3, and an unlocking position in which the second magnet 56 is magnetically connected to the pressure plate 3, wherein the first magnet 55 and the second magnet 56 can be nickel-cobalt magnets; when the side rod 51 is in the locking position, the distance between the second magnet 56 and the inner top wall of the groove 31 is greater than the width of the spring sheet 52 in the axial direction of the threaded rod 41, so that after pushing up the second magnet 56 to make the second magnet 56 magnetically connected to the pressure plate 3, the ratchet 54 can be completely separated from the ratchet groove 53, which makes it convenient for the staff to loosen the threaded rod 41.

[0042] In this embodiment, the pressure plate 3 is fixedly mounted on the diverter plate body 1 by means of a fastener 6 , and the fastener 6 may be a hexagonal bolt.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
