Embodiment Construction

[0038] In order to overcome the aforementioned drawbacks of the prior art solutions, the present invention proposes a solution which is conceptually different and which ensures the desired aesthetic quality of the molded components, as well as for the production, procurement and commissioning of injection molding Less time and cost required for equipment. Basically, the element of the invention consists of an slug, called a gate slug, positioned near the gate (where present) in a conventional gate slug, or directly at the edge of the mold pattern or plate. seat.

[0039] see first Figure 7 and 8 , where the same or similar referenced Figure 1-6 Parts of those said, the gate insert is indicated by 15 and it is screwed into the mold insert 14 which rests at the lower part against the seat 16 of this mold insert 14 near the gate 5 (with a conical surface).

[0040] In detail, and if Figures 10 to 12 As shown in the figure, the gate insert 15 is composed of a metal hollow...

Abstract

The invention relates to an apparatus for injection moulding of a plastic material. Specifically, the apparatus includes a mould having at least one gate (5) towards a moulding cavity and at least oneinjector (2) cooperating with the gate (5). The gate (5) is formed by a gate insert (15) screwed and arranged resting on a centring seat (16) with conical surface of the mould.

Description

technical field [0001] The invention relates to an apparatus for injection molding of plastic materials comprising a mold with at least one gate facing the mold cavity and at least one injector cooperating with the gate. The injector typically includes a nozzle provided with a nozzle tip defining a passage for the plastic material to flow towards the gate. Background technique [0002] Attached figure 1 A conventional injection molding apparatus is schematically presented in partial section in : it comprises a hot runner or distributor 1 for the fluid plastic material, and a cavity for introducing the pressurized plastic material through the corresponding gate 5 into the mold One or more injectors 2,3, the mold plate or die are indicated by 4. [0003] Each injector 2, 3 comprises a tubular nozzle 7 provided with a nozzle tip indicated generally at 8, which defines a fluid passage for the injected plastic material. exist figure 1 In this case, the syringes 2, 3 are of th...
