Abstract
The utility model provides a pouring structure of a hot runner mold, which comprises a hot runner, a cavity communicated with an injector of the hot runner, and a connecting passage arranged between the injector of the hot runner and the cavity. The injector of the hot runner is communicated with the cavity through the connecting passage, the size of the connecting passage which is a cold runner is determined according to the size of a practical product, the hot runner and the cavity are not connected directly, shortages of burrs, tips and the like of products are avoided, the products never deform, quality of the products is higher, and waste of raw materials and manpower is avoided.
Description
Technical field
The utility model relates to the injection mold technical field, specifically is a kind of cast structure of hot runner mould.
Background technology
In the cast structure of the hot runner mould of routine, the nozzle of hot flow path docks the injection moulding sizing material with the die cavity of mould, this cast structure can reach injection moulding effect preferably for the bigger product of some structures, but the space at product that some volumes are less or die cavity glue-feeder place is during less than the end of sprue, and this injection moulding mode burr can occur when reality is used.Many defectives such as wedge angle, or even cause the variation of cavity structure, after finishing, injection moulding causes the distortion of this portioned product in the die cavity easily, and influence the quality of product, and then cause unnecessary waste.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of defective of product few, avoid product distortion, the cast structure of the hot runner mould that improves the quality of products.
For solving the problems of the technologies described above, the cast structure of the mould that the utility model provides, it comprises hot flow path, with the die cavity that the nozzle of hot flow path is communicated with, is provided with interface channel between the nozzle of described hot flow path and the die cavity.
After adopting above structure, the cast structure of the utility model mould compared with prior art has the following advantages:
Realize being communicated with by interface channel between the nozzle of hot flow path and the die cavity, this interface channel is a cold runner, the size of interface channel can be determined according to the size of actual product, hot flow path directly is not connected with die cavity, avoid product defectives such as burr, wedge angle to occur, and product can not be out of shape, and the quality of product is also just higher, has avoided raw material and artificial waste.
Description of drawings
Fig. 1 is the structural representation of the cast structure of the utility model mould;
Fig. 2 is the structure for amplifying schematic diagram at A place among Fig. 1;
Wherein, 1, hot flow path; 2, die cavity; 3, interface channel.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in drawings, the cast structure of the utility model hot runner mould, it comprises hot flow path 1, the die cavity 2 that is communicated with the nozzle of hot flow path 1, in the cast structure of the utility model mould, be provided with interface channel 3 between the nozzle of hot flow path 1 and the die cavity 2, the internal diameter of this interface channel 3 is much smaller, do not influence the structure at die cavity 2 charging aperture places, die cavity 2 separates with the nozzle of hot flow path 1, has also just avoided product the defectives such as distortion of burr, wedge angle and product to occur, and the product quality of producing is also just reliable, substandard products and waste product are less, also conservation comparatively.
Claims (1)
1. the cast structure of a hot runner mould, it comprises hot flow path (1), the die cavity (2) with the nozzle of hot flow path (1) is communicated with is characterized in that: be provided with interface channel (3) between the nozzle of described hot flow path (1) and the die cavity (2).
