Further, the template groove comprises a first die groove and a second die groove, and the first die groove and the second die groove correspond to the third die groove.

Furthermore, the injection hole comprises a first runner and a second runner, the first runner is arranged at the lower part of the second template and is positioned in the first die cavity, and the second runner is arranged at one side of the second template and is positioned in the second die cavity.

Further, the first die cavity is divided into a first area and a second area, the first area surrounds the outer side of the upper end of the second area, and the first area penetrates through the second die plate.

Further, the second die cavity comprises a third area and a fourth area, and the third area is communicated with the fourth area.

The utility model discloses an above-mentioned technical scheme's beneficial effect as follows:

the first runner and the second runner can reduce the abrasion of the melting material to the single runner, effectively prolong the service life of the runners, effectively solve the requirement of particle fluidity and reduce the use standard of raw materials.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 3 of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

Example one

As shown in fig. 1-3: the utility model provides an extrude a mouthful mould, includes first template 1 and second template 2, has seted up the filling hole on the second template 2, and the template groove that corresponds with the filling hole is seted up to the inboard of second template 2, sets up the third die cavity 8 that runs through first template 1 on the first template 1, and third die cavity 8 corresponds with the template groove, and the upper and lower both ends of first template 1 and second template 2 all offer the mounting hole 3 that is used for making things convenient for first template 1 and the installation of second template 2.

In this embodiment, the first flow channel 4 and the second flow channel 5 can reduce the wear of the melted material on the single flow channel, thereby effectively prolonging the service life of the flow channel, wherein the first flow channel 4 and the second flow channel 5 can also effectively resolve the particle fluidity requirement, and the use standard of the raw material is reduced.

Example two

As shown in fig. 3, the difference from the first embodiment is that: the die plate grooves comprise a first die groove 6 and a second die groove 7, and the first die groove 6 and the second die groove 7 correspond to a third die groove 8
