Abstract
The invention discloses an improved main filling nozzle structure for a hot runner system. A main filling nozzle forms a containing cavity along the circulation direction of a hot runner; the containing cavity comprises a cavity bottom and a cavity body; the cavity body is cylindrical and is matched with an injection nozzle of an injection machine; the cavity bottom is cylindrical and is matched with a nozzle head of the injection machine; and the injection nozzle of the injection machine can be inserted into the containing cavity. According to the improved main filling nozzle structure for the hot runner system, provided by the invention, the main filling nozzle is provided with the containing cavity capable of containing the injection nozzle of the injection machine, so that when products are injected, the injection nozzle of the injection machine can extend into the main filling nozzle, and after the injection is finished, a suck-back phenomenon is generated when the injection nozzle of the injection machine retreats, excessive plastics are drawn back; and the problem of gate towering is solved, and the product quality is improved.
Description
Technical field
The present invention relates to TOP-TIP, be specifically related to a kind of injection owner and fill with the mouth structure-improved.
Background technology
In TOP-TIP, when the high pitched tune injection product, injection machine injection nozzle and main filling mouth are only Surface Contacts, do not enter the inside of main filling mouth, can produce so the raised phenomenon of cast gate, affect the quality of product.
Summary of the invention
In order to overcome defects, the invention provides a kind of TOP-TIP with main filling mouth structure-improved, this TOP-TIP has solved the raised problem of cast gate with main filling mouth structure-improved, has improved product quality.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of TOP-TIP is with main filling mouth structure-improved, described main filling mouth forms host cavity along the hot flow path circulating direction, at the bottom of described host cavity comprises the chamber and cavity, described cavity is cylindric with injection machine injection nozzle coupling, at the bottom of described chamber for the mouth of injection machine injection nozzle be complementary round table-like, described injection machine injection nozzle can be inserted in described host cavity.
As a further improvement on the present invention, when described injection machine injection nozzle was inserted in described host cavity, the mouth of described injection machine injection nozzle is at the bottom of the described host cavity chamber, and was gapped between the chamber wall of the outer wall of described injection machine injection nozzle and described host cavity cavity.
The invention has the beneficial effects as follows: TOP-TIP of the present invention is provided with a host cavity that can hold injection machine injection nozzle with main filling mouth structure-improved on main filling mouth, make when injection product, injection machine injection nozzle can be deep into the inside of main filling mouth, thereby after completing injection, when withdrawing from, injection machine injection nozzle produces the suck-back phenomenon, unnecessary plastics are drawn back, solved the raised problem of cast gate, improved the quality of product.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Embodiment: a kind of TOP-TIP as shown in Figure 1 is with main filling mouth structure-improved, described main filling mouth forms host cavity 1 along the hot flow path circulating direction, described host cavity comprises at the bottom of the chamber 2 and cavity 3, described cavity is cylindric with injection machine injection nozzle coupling, at the bottom of described chamber for the mouth of injection machine injection nozzle be complementary round table-like, described injection machine injection nozzle can be inserted in described host cavity, make that injection machine injection nozzle retreats the time produce one suction, with unnecessary plastics pumpback out, avoid the raised problem of cast gate.
Better, when described injection machine injection nozzle is inserted in described host cavity, the mouth of described injection machine injection nozzle is at the bottom of the described host cavity chamber, and gapped between the chamber wall of the outer wall of described injection machine injection nozzle and described host cavity cavity, described gap length determines according to the gauge size of injector.
Claims (2)
