The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Referring to fig. 1-3, the utility model discloses an end face feeding injection molding machine, including:
a fixed seat 100 horizontally disposed on a working surface;

the injection molding mechanism 400 is fixed on the fixed seat 100 and is positioned on one side of the fixed plate 200 away from the forming die 300, and the injection molding mechanism 400 is used for extruding glue;
one end of the injection molding pipeline 500 is connected with the injection molding mechanism 400, the other end of the injection molding pipeline 500 penetrates through the feeding through hole 210 and the feeding channel and is communicated with the cavity for conveying the rubber material to the cavity, and a heating ring 550 is arranged on the outer peripheral wall of the injection molding pipeline 500;
the injection molding pipeline 500 comprises a first pipeline 510, one end of the first pipeline is connected with the injection molding mechanism 400, the other end of the first pipeline is connected with at least one second pipeline 520, and one end, far away from the first pipeline 510, of the second pipeline 520 penetrates through the feeding through hole 210 to be communicated with the cavity.
The specific implementation steps and the principle are as follows: firstly, the injection molding mechanism 400 extrudes the rubber material to the injection molding pipeline 500, and then the rubber material sequentially passes through the feeding through hole 210 and the feeding channel through the injection molding pipeline 500 and then enters the cavity for mold closing and shaping. Preferably, a nozzle 560 is provided at the end of injection molding pipe 500, and the compound enters the cavity through nozzle 560.
The phenomenon of cooling and solidifying the rubber material in the injection molding pipeline 500 is a problem to be solved urgently in the field, that is, after one-time injection molding is completed, the injection molding of the rubber material waiting mold 300 is stopped to shape the rubber material in the cavity, and the next injection molding can be performed after the mold closing is completed and the product in the cavity is taken out. During this waiting (injection stopping), the glue in the injection pipe 500 may decrease with time or other external factors, causing the glue to cool or even solidify in the injection pipe 500, affecting the next injection or causing the injection to be unable to continue. Therefore, be provided with heating ring 550 on the periphery wall of the pipeline 500 of moulding plastics in this scheme, the heating ring heats the pipeline 500 of moulding plastics for the sizing material in the pipeline 500 of moulding plastics is keeping normal temperature throughout, can keep the temperature of sizing material in the pipeline 500 of moulding plastics in longer time to be in normal scope, and then has guaranteed the normal clear of moulding plastics many times in succession.

In the prior art, the injection mechanism 400 is perpendicular to the end surface of the mold 300, so the injection pipe 500 connected to the injection mechanism 400 needs to bypass the end surface of the mold 300 and then enter the cavity from the radial surface of the mold 300. It is to be understood that: the scheme sets that the injection molding pipeline 500 directly penetrates through the feeding through hole 210 in the fixing plate 200 and enters the cavity from the end face of the section mold 300, so that the length of the injection molding pipeline 500 is shortened, and the rubber material in the injection molding pipeline 500 can enter the cavity under the action of smaller extrusion force by shortening the length of the injection molding pipeline 500. Therefore, this scheme still has the cost-effective, improves the advantage of the efficiency of moulding plastics.
