Abstract

The invention discloses a round pin-point gate pouring molding structure. The structure comprises a supporting mechanism, a mold closing mechanism is arranged at the top of the upper end of the supporting mechanism, a base plate is arranged at the bottom of the lower end of the supporting mechanism, screws are arranged on the periphery of the outer side of the supporting mechanism, and a lower mold cavity is formed in the top of the upper end of the supporting mechanism. A molding mechanism is arranged on the inner side of the upper end of the mold closing mechanism. Auxiliary feeding mechanisms are arranged on the two sides of the interior of the molding mechanism. According to the structure, a heating wire layer is used for heating the upper mold cavity, so that the situation that the temperature in the mold cavity is too low, water vapor is generated due to direct contact with melt, even the water vapor is accumulated in the mold cavity, flowing and molding pressure of the melt are affected, and bubbles are generated in a product is avoided. Through the heating of the heating wire layer, preheating operation can be carried out before molding, so that the situation that melt flows discontinuously in the mold cavity due to too large mold temperature difference is avoided.

Description

technical field

[0001] The invention relates to the technical field of injection moulds, in particular to a circular thin nozzle inlet casting mold structure. Background technique

[0002] Today, the sprue is the last hurdle for molten plastic to enter the mold cavity through the gating system. It is the feed channel connecting the runner and the cavity, and it is also the shortest part. Its function makes the molten plastic accelerate when it enters the cavity, which is conducive to The cavity is filled quickly, and the plastic at the gate condenses first after molding to seal the cavity, prevent the molten plastic from flowing backwards, and prevent the pressure of the cavity from dropping too fast, resulting in shrinkage cavities or depressions on the product. Separation to shape the product.

[0003] The structure technology of the circular fine nozzle pouring mold on the market mainly relies on pouring of molten materials to form the injection molded product, and uses ...
