Embodiment Construction
[0016] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] Such as figure 2 Shown is a schematic structural view of the horn gate inlet of the present invention. Please refer to image 3 and Figure 4 As shown, the horn gate inlet is applied to products that need latent glue in the mold, and 10 is a molded product. The mold includes a female mold 200 and a male mold 300 that can be opened and closed. include:
[0018] An entry subunit 100, which is arranged in the male mold 300;
[0019] A horn runner 110, which is located in the inlet monomer 100, one side of the inlet monomer 100 cooperates with the male mold 300 to form the horn runner 110, the horn runner 110 is shaped like Horn-shaped smooth curved cone, the cross-sectional size of the horn runner 110 gradually decreases;
[0020] A horn gate 111 is arranged at the junction between the tip of the horn runner 110 and the product ...

The invention relates to a horn gate insert, which is applied to products needing submarine plastic filling in a die. The die comprises a male die and a female die able to be opened and closed. The horn gate insert comprises: an insert monomer, which is arranged in the male die; a horn flow channel, which is arranged in the insert monomer, is formed by cooperation of one side of the insert monomer and the male die, is in the shape of a horn type smooth curved cone, and has a gradually diminished sectional dimension; and a horn gate, which is disposed at the joint of the horn flow channel's tip and the product. According to the invention, the gate of the horn gate insert is totally designed on one insert monomer. With the horn gate insert provided by the invention, the die production cost is reduced, the die production efficiency is improved, the previous horn gate insert's assembly form is simplified, and the die assembling difficulty is lowered, thus being conducive to improvement of effective working hours.
Description
【Technical field】 [0001] The invention relates to an insert, in particular to an insert with a horn gate. 【Background technique】 [0002] In the injection molding process of plastic molds, especially the injection molding of mobile phone battery covers, the horn injection mechanism is usually used, such as figure 1 As shown, it is a corner gate gate in the prior art. The existing horn gate gate generally has two gates, and half gate forms are designed on the two gates, and then the two The inserts are put together to form the horn gate inserts and are assembled in the core of the mold. Existing corner gate gates, the gate forms of the two gates included in it all need EDM, and the processing method of the gates is calculated by the manufacturer. If the number of gates in a set of molds More, then the cost of the mold will increase exponentially. [0003] In view of this, it is necessary to provide an insert to simplify the assembly form of the horn gate insert, reduce the...
