Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] see figure 1 , the all-electric injection molding machine clamping gear box transmission mechanism, including crosshead 2, clamping tail plate 3, clamping front plate 3', drive motor 4, rack and pinion 5 and gear reducer box A; wherein, the cross The head 2 and the mold clamping tail plate 3 are connected to the mold clamping front plate 3' through the transmission mechanism, the crosshead 2 is placed between the mold locking tail plate 3 and the mold locking front plate 3', the mold locking tail plate 3 is relatively stationary, The plate 3' realizes the mold opening and / or mold clamping movement with the reciprocating movement of the crosshead 2 through the transmission mechanism; the rack and pinion 5 passes through the mold clamping tail plate 3 and connects with the crosshead 2, and the drive motor 4 drives the rack and pinion 5 to reciproca...

Abstract

The invention discloses a gear reducer transmission mechanism for mold locking of an all-electric injection molding machine. The gear reducer transmission mechanism comprises a crosshead, a mold-locking tail plate and a mold-locking front plate, wherein the crosshead and the mold-locking tail plate are connected with the mold-locking front plate through a transmission mechanism. The gear reducer transmission mechanism is characterized by further comprising a gear rack connected with the crosshead after penetrating through the mold-locking tail plate; the gear rack is driven by a driving motor to reciprocate, so as to act on the crosshead to realize the mold locking motion. According to the gear reducer transmission mechanism disclosed by the invention, the gear rack is used for substituting the ball screw for the mold locking of the conventional injection molding machine; in comparison, the gear rack is free of the sliding phenomenon in the transmission process due to the rack transmission manner and high in transmission performance; particularly, the gear rack is arranged as bilateral racks; the two racks are simultaneously subjected to gear transmission, so that the stress of the gear rack can be balanced, the gear rack can be ensured to reciprocate on the axis, further the mold locking can be successfully performed, and meanwhile the abrasion can be reduced; the gear reducer transmission mechanism has the characteristics of being simple and reasonable in structure, reliable in performance, and durable.

Description

technical field [0001] The invention relates to a transmission structure for mold clamping of an injection molding machine, in particular to a gear reduction box transmission mechanism for mold clamping of an all-electric injection molding machine. Background technique [0002] In the ball screw connection mechanism of the injection molding machine in the prior art, the movement trajectory of the crosshead of the toggle linkage type injection molding machine is theoretically a straight line parallel to the guide post, which is generally formed by the guide rod installed on the mold clamping tail plate. It is determined by the guide sleeve installed on the crosshead, but due to the processing errors of the clamping tail plate, crosshead and other related parts, and the parallelism of the mold during injection molding production, there is also a deviation, which will affect the movement track of the crosshead. Make the motion trajectory deviate from the theoretical design. Th...
