Abstract

The invention discloses a die assembly device which comprises a die assembly component and a positioning part. The die assembly component comprises a first die assembly mechanism, a second die assembly mechanism, a cutter and an ejector post. The second die assembly mechanism can be spliced to the first die assembly mechanism in one die assembly direction to form a die cavity. The cutter can move between the pouring position and the cutting position in the die assembly direction. An auxiliary sprue is arranged on the cutter and used for die injection forming of an auxiliary connection portion, and the cutter can cut off the auxiliary connection portion when located at the cutting position. The ejector post can move between the limiting position and the non-limiting position in the die assembly direction, can abut against the cutter at the pouring position when located at the limiting position, and allows the cutter to move from the pouring position to the cutting position when located at the non-limiting position. The positioning part can position the ejector post at the limiting position. In the die assembly process, the die assembly device can directly cut off the auxiliary connection portion which is formed by the auxiliary sprue in a die injection mode, time and labor are saved, and labor cost is reduced.

Description

technical field [0001] The invention relates to a mold clamping device, in particular to a mold clamping device with an auxiliary gate. Background technique [0002] In the mold closing process of some products, it is necessary to set up auxiliary gates to help injection molding, such as the block lever used in low pressure products, such as figure 1 As shown, the blocking rod has a first end 62 that can rotate with the operating part of the circuit breaker, and a second end 64 that can touch the contact of the circuit breaker driven by the first end 62. The first end 62 and the second end 64 are connected by a thinner connecting portion 63 such as a connecting rib, so as to disconnect the connecting portion 63 and protect the circuit when an overload or a short circuit occurs. Because the structure of the connecting part 63 is very thin, in order to ensure that the first end 62 and the second end 64 of the blocking rod can be completely injection molded, the mold injection...
