The common point of the above molds is to have a cavity in the interior, and then the raw material. (For example, molten metal, rubber plastic or other liquid raw materials) is poured into the cavity, and under proper molding conditions, the finished product having a predetermined appearance shape can be formed in the cavity. However, in the practical operation of the mold, the raw material is not It can smoothly reach all corners of the cavity, which involves the material, temperature and pressure of the mold machinery itself, the material properties and fluidity of the raw materials, the problem of the material generated after the raw material enters the cavity, and the shape of the cavity is particularly complicated. In the molding product # which will affect the final product, in order to make the second: 々, in the mouth of the human body, Feng 枓 枓 can smoothly reach every corner of the cavity, the operator usually adds equipment in the mold 2 The vacuum device is used to blow the suction hole to assist the raw material to smoothly enter the cavity to complete the molding operation. Referring to Fig. 1, the conventional mold device 10 has a lower 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 19 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , a ... a seat 101 of a predetermined shape, an upper die holder: the recess 5 is formed with a recess 11 on the inner side of the recess 11 and a feed port 111 communicating with the front end of the cavity 5 M312367 101, the raw material The 丨 is injected directly into the cavity 101 by the inlet U1.

Although the raw material i has the effect of attracting the feed, the air valve 13 is set in the mold. At the end of the hole 1〇1, if there is a cavity in the middle that is complicated, the distribution path is wide, or there are many dead corners, there is an inaccessible place. At this time, the manufacturer will adopt the method of increasing the raw material ^ to force the raw material i to be As a result, the μ ir sifted out to a more sturdy position. The lower mold base u, 12 was squeezed out because the internal filling pressure was too large, and a gap was formed at the mold clamping, M312367 finished product. A large amount of burrs are generated on the surface, which seriously affects the appearance of the product, and if the internal force is too large, the upper and lower mold bases u and 12 are easily deformed and it is difficult to mold, resulting in a decrease in the service life of the mold, and even worse, the mold may be damaged. : Can not be used again, in order to solve the problem of mold damage, the industry will use the strength of the metal material to make the eye lL rr ^ thin Hobe table into a puller, which in turn faces a significant increase in the cost of the mold 'does not match The problem of benefit...Bu also has the means to reduce the number of mold holes 101, so that the number of molds in the original single-mold set is reduced, and by the effect of shortening the flow path of the raw material i, the raw materials will reach H Filling the effect of the entire mold R 101, but as a result, the number of finished products that the mold mother has formed earlier will be reduced, which will result in a decrease in productivity.
