Technical Field

[0001] The utility model relates to a road cone machine, in particular to an injection head installation structure of a disc road cone machine. Background Art

[0002] The feeding nozzle of the disc road cone machine in the prior art is in a suspended state after installation, so the installation strength is low, which affects the service life.

[0003] Reference Figure 1 As shown in the figure, the injection head installation structure of the disc cone machine in the prior art is shown. The installation structure is installed by means of a long bolt D2, and needs to be limited by the push rod D1. The limit of the push rod D1 needs to ensure that the extension degree of each push rod D1 is the same. Moreover, based on this assembly structure, it is easy to increase the length of the discharge channel D3 of the feed nozzle D4, and the material injection requirements are also increased. For example, it is necessary to maintain the temperature of the feed nozzle D4 to avoid the increase in viscosity of the material during cooling, which affects the injection effect. One of the purposes of the prior art adopting this connection method is to reduce the problem that the feed nozzle D4 causes the temperature of the cover plate D5 to rise, affecting the product molding effect. Moreover, the injection head is installed in the air, and the installation strength is low, which is easy to affect the service life.

[0004] Therefore, the existing technology needs to be further improved to facilitate installation and achieve better injection effect. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an injection head mounting structure for a disc road cone machine, which can make the installation of the feed nozzle more stable and also achieve good injection and molding effects.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection head mounting structure of a disc road cone machine, comprising a shell for being mounted and fixed in cooperation with an external bracket, a feed nozzle arranged in the shell, and an injection head for feeding; the feed nozzle is mounted on the injection head, and the injection head is fixedly connected to the shell, a liquid injection hole and a plurality of assembly holes are arranged on the shell at positions corresponding to the mold, and the liquid injection hole is connected to a liquid outlet of the feed nozzle, and the liquid outlet of the feed nozzle is embedded in the liquid injection hole; the shell is also fixedly connected to the injection head by bolts and assembly holes; a heat insulation board is provided between the shell and the injection head, and two sides of the heat insulation board are respectively fitted with the shell and the injection head.

[0007] As a further improvement of the utility model, the shell includes a base plate and a cover body installed on the base plate; the injection hole and the assembly hole are both located on the base plate, and the cover body has a space for accommodating an injection head and a feed nozzle. When the cover body is installed with the base plate, the injection head and the feed nozzle are located in the space; the heat insulation board is located between the injection head and the base plate.

[0008] As a further improvement of the utility model, the heat insulation board has a through hole for the bolt to pass through, and the through hole corresponds to the assembly hole.

[0009] As a further improvement of the utility model, a mounting disk is radially arranged on the feed nozzle, and the feed nozzle is mounted on the injection head by the mounting disk and bolts; a through groove for embedding the feed nozzle is arranged on the heat insulation board, and the shape of the through groove is adapted to the mounting disk so that the mounting disk and the feed nozzle can be embedded.

[0010] As a further improvement of the present invention, the assembly disk is circular.

[0011] As a further improvement of the utility model, the end of the feeding nozzle is flush with the opening of the injection hole at one end of the mold.

[0012] The beneficial effect of the utility model is that the heat insulation board is used for heat insulation, which can prevent the temperature of the injection head from being excessively transferred to the shell, thereby preventing the material molding effect from being affected by the high temperature of the cover plate. In addition, the injection head and the feed nozzle are directly mounted on the shell by bolts and fit with the heat insulation board. This structure can make the installation more tight and stable, and at the same time, there is no need for horizontal calibration through the ejector rod, and the installation difficulty is low. In addition, the length of the feed nozzle discharge channel can be shortened, so that the injection effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] Reference Figure 1-7 As shown,

[0023] A mounting structure for an injection head of a disc road cone machine, characterized in that it comprises a shell 1 for being mounted and fixed in cooperation with an external bracket, a feed nozzle 2 arranged in the shell 1, and an injection head 3 for feeding; the feed nozzle 2 is mounted on the injection head 3, and the injection head 3 is fixedly connected to the shell 1, a liquid injection hole 13 and a plurality of assembly holes 14 are arranged on the shell 1 at positions corresponding to the mold, and the liquid injection hole 13 is connected to the liquid outlet of the feed nozzle 2, and the liquid outlet of the feed nozzle 2 is embedded in the liquid injection hole 13; the shell 1 is also fixedly connected to the injection head 3 by bolts and assembly holes 14; a heat insulation board 4 is provided between the shell 1 and the injection head 3, and two sides of the heat insulation board 4 are respectively fitted with the shell 1 and the injection head 3.

[0024] The feed nozzle 2 and injection head 3 in this solution can be partially protected by the shell 1, and the feed nozzle 2 injects the material into the mold through the injection hole 13 on the shell 1, and the shell 1 is installed with the external bracket to fix the position of the shell 1, and the injection head 3 is fixedly installed on the shell 1, so the injection head 3 is in a stable installation state, and through the cooperation between the feed nozzle 2 and the injection hole 13, the material can be injected through the injection hole 13 and injected into the mold. When the injection head 3 is installed with the shell 1, the bolts are first inserted into the assembly hole 14 from the outside of the shell 1 and then connected to the injection head 3, and the bolts are rotated to form a threaded connection until it is installed in place. The setting of the heat insulation plate 4 can reduce heat conduction between the injection head 3 and the shell 1, and prevent the shell 1 from being too hot, acting as a cover plate to affect the molding of the material in the lowered mold.

[0025] Specifically, the housing 1 includes a base plate 11 and a cover body 12 installed on the base plate 11; the injection hole 13 and the assembly hole 14 are both located on the base plate 11, and the cover body 12 has a space for accommodating the injection head 3 and the feed nozzle 2. When the cover body 12 is installed with the base plate 11, the injection head 3 and the feed nozzle 2 are located in the space.

[0026] The bottom plate 11 is a component used to match the mold. Since the assembly hole 14 is located on the bottom plate 11, the injection head 3 is also installed on the bottom plate 11, and the feed nozzle 2 is also embedded in the injection hole 13 on the bottom plate 11. The cover body 12 is installed with the external bracket, and then the feed nozzle 2 is installed on the injection head 3, and then the injection head 3 is installed on the bottom plate 11, and the bottom plate 11 is installed with the outer cover to complete the overall installation.

[0027] The bottom plate 11 and the outer cover can be fixedly connected by fastening with bolts.

[0028] In a further improvement, the heat insulation board 4 has a through hole for the bolt to pass through, and the through hole corresponds to the assembly hole 14.

[0029] The heat insulation board 4 can be made of a hard material with heat insulation function or a flexible material.

[0030] When a hard material is used, it can be used as an adjustment tool, for example, by using heat insulation boards 4 of different thicknesses to adjust the positions of the feed nozzle 2 and the injection head 3 .

[0031] Of course, flexible materials can also be used to act as buffers and tensioners.

[0032] In addition, in a specific setting, a mounting disk 21 is radially arranged on the feed nozzle 2, and the feed nozzle 2 is mounted on the injection head 3 by the mounting disk 21 and bolts; a through groove 41 for embedding the feed nozzle 2 is arranged on the heat insulation plate 4, and the shape of the through groove 41 is adapted to the mounting disk 21 so that the mounting disk 21 and the feed nozzle 2 can be embedded.

[0033] By utilizing the cooperation between the assembly disk 21 and the through groove 41, the positioning function can be achieved, and the radial support effect of the feed nozzle 2 can be improved. In addition, the assembly disk 21 can be circular as shown in the figure. Under this setting, the installation between the assembly disk 21 and the heat insulation board 4 can be more convenient. For example, during the installation process, the heat insulation board 4 is first installed on the feed nozzle 2, and the through groove 41 is matched with the assembly disk 21, and then the injection head 3 with the feed nozzle 2 is installed on the base. At this time, the feed nozzle 2 is embedded in the liquid outlet hole on the base, and then the heat insulation board 4 is rotated to make the through hole of the heat insulation board 4 correspond to the assembly hole 14, and then the bolts pass through the heat insulation board 4 smoothly and are assembled with the injection head 3.

[0034] In a preferred arrangement, the end of the feeding nozzle 2 is flush with the opening of the injection hole 13 at one end of the mold.

[0035] The flush state of the ends allows for better action and alignment of the injected material.

[0036] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
