Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of injection molding machine nozzles, and in particular to an injection molding machine nozzle with a melting function. Background Art
[0002] The nozzle of the injection molding machine needs to be deployed close to the mold, and it is impossible to use the heater outside the barrel to insulate and melt the injection molding material inside. Therefore, an electric heating jacket is usually added to the outside of the nozzle close to the barrel to achieve the function of the nozzle to insulate and melt the injection molding material.
[0003] During the long-term use of the injection molding machine, the surface of the equipment will be contaminated with impurities such as oil. During the injection molding operation, the injection nozzle will be exposed to the outside and easily contaminated by oil dripping from the equipment. Especially during the injection molding operation of white plastic parts, the oil adhering to the injection molding nozzle will lead to a decrease in the production yield of the injection molded parts.
[0004] The inventor has invented an injection molding machine nozzle with a melting function. A retractable structure is arranged on the outside of the injection molding machine nozzle to shield the injection molding machine nozzle to prevent oil stains dripping from the top of the front fixed template from adhering to the nozzle of the injection molding machine nozzle. Since the working space between the injection molding machine nozzle and the front fixed template is prioritized, the retractable structure is installed on the outside of the electric heating sheath to avoid interference between the retractable structure and the front fixed template.

[0045] The inner tube 7 and the guide tube 51 cooperate to guide the movement of the baffle 6 on the bracket 5 .
[0046] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a slope 61 is fixedly provided on the top of the baffle 6, and the front end height of the slope 61 is higher than the rear end height thereof.
[0047] The design of the slope 61 adopts a structure that is high in the front and low in the back, so as to prevent the oil stains adhering to the baffle 6 from dripping from the front of the baffle 6 .
[0048] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a buffer pad 8 is movably engaged at the front end of the baffle plate 6 , and the front portion of the buffer pad 8 abuts against the rear side of the front fixed template 1 .
[0049] The movable snap-fit design between the buffer pad 8 and the front portion of the baffle 6 facilitates the user to replace the dirty buffer pad 8 .
[0050] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
