Green rod pulling mechanism in injection molding machine

Abstract

This utility model relates to a Green Bar pull-out mechanism in an injection molding machine, comprising: a fixed beam; a sliding plate slidably disposed at the bottom of the fixed beam; and a connector connecting the sliding plate and the steel head of the Green Bar. The connector includes a vertical portion, the top of which is horizontally folded to form a horizontal portion connected to the sliding plate. The bottom of the vertical portion has an arc-shaped notch adapted to the vertical annular surface of the steel head end. Multiple connecting holes are provided near the arc-shaped notch at the bottom of the vertical portion. A locking member passes through the connecting holes and connects to the vertical annular surface, connecting the connector to the steel head. By using the connector to connect the steel head to the sliding plate, a quick connection between the sliding plate and the pull-out mechanism is achieved without requiring secondary processing of the connector.

Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, and in particular to a Green bar pull-out mechanism in an injection molding machine. Background Technology

[0002] Green columns are rod-shaped components installed on injection molding machines to provide traction. Their principle is to balance the sliding of the mold plate and bear the tension brought about by mold clamping; they are an important part of the injection molding machine industry.

[0003] For a conventional connection between the Green Column and the pull-out mechanism, please refer to Chinese Patent Publication No. CN215396499U, such as... Figure 4 As shown, Figure 4 The steel head 4 of the middle Green rod is detachably equipped with two connecting columns 42. The slide plate 2 has a connecting hole, through which the connecting columns 42 pass, and the two are connected by a bushing. In this way, the movement of the slide plate 2 drives the Green rod to move axially. However, during the installation process, the connecting columns 42 need to be matched with the steel head 4 of the Green rod first. After the matching is completed, the connecting columns 42 are connected to the slide plate 2. Because the height of the connecting columns 42 is too high, the connecting columns 42 will protrude from the slide plate 2 and interfere with the fixed beam 1. Therefore, the connecting columns 42 need to be disassembled and processed to shorten the axial length of the connecting columns 42 before matching with the slide plate 2, which increases the installation time.

[0018] Figure 4 This is a diagram showing the connection between a standard pull-out mechanism and the steel head of the Green rod. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] See Figure 1 , Figure 1 The diagram shows the connection between the pull-out mechanism and the steel head of the Green rod. In the diagram, the fixed beam 1 is fixedly installed, and the bottom of the fixed beam 1 is slidably equipped with a sliding plate 2. The bottom of the sliding plate 2 is equipped with a connecting piece 3 that connects to the steel head 4. When it is necessary to change the mold, the sliding plate 2 drives the connecting piece 3 and the steel head 4 to move along the length of the fixed beam 1. At this time, the Green rod performs an axial pull-out motion.

[0021] See Figure 2 , Figure 2 This is a schematic diagram of the pull-out mechanism. In the diagram, the bottom of the fixed beam 1 is fixed with a slide rail 11, the top of the slide plate 2 is provided with a slider 21 that cooperates with the slide rail 11, and the bottom of the slide plate 2 is provided with a connecting piece 3.

[0022] SeeFigure 3 , Figure 3 for Figure 2 The enlarged view at point A shows that the connector 3 includes a vertical part 31, a horizontal part 32 at the top of the vertical part 31, a fastener passing through a fastening hole 33 on the horizontal part 32 and connecting to the bottom of the slide plate 2, a connecting hole 34 on the vertical part 31, and a locking member passing through the connecting hole 34 and connecting to the vertical annular surface 41 of the end face of the steel head 4; reinforcing ribs 35 are provided on both sides of the vertical part 31 and connected to the horizontal part 32, thus ensuring that the overall strength of the connector 3 is not easily deformed.

[0023] The bottom of the vertical part 31 is an arc-shaped notch 36, which matches the vertical annular surface 41. By setting the arc-shaped notch 36, the contact area between the connector 3 and the steel head 4 can be increased, thereby improving the connection strength between the connector 3 and the steel head 4.

[0024] The vertical part 31 has outwardly extending ears 37 on both sides. The ears 37 are provided with connecting holes 34. The connecting holes 34 also serve to allow the locking part to pass through and connect with the steel head 4. By providing the connecting holes 34 on the ears 37, the contact points between the connector 3 and the steel head 4 are increased, ensuring the connection strength between the connector 3 and the steel head 4.

[0025] The aforementioned connecting hole 34 is an adjustment waist hole, which allows the connector 3 to be adapted to steel heads 4 of different specifications. In addition, the adjustment waist hole enables the connection between the slide plate 2 and the steel head 4. That is, if there is a height difference between the slide plate 2 and the steel head 4, the slide plate 2 and the steel head 4 can be quickly connected by adjusting the waist hole and the locking part, without the need for secondary processing.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
