    • A mold core having an upper surface and at least one hole passing therethrough is provided. An ejector pin is disposed within at least one of the holes in the mold core. The ejector pin includes a bushing having an undercut portion protruding above the upper surface of the mold core for enhancing the adherence of a part molded on the mold core thereto. The bushing also has a hole passing laterally therethrough through which passes an ejector pin shaft. The ejector pin shaft, which includes a head, forces a part adhered to the mold core off of the mold core when so desired. The protruding portion of the bushing is undercut in the form of a back-drafted angle, a circumferential rib, either indented or projecting, and of a partially round or V-shaped cross-section, a series of dimples, or of any other shape which will cause the molded plastic to adhere tightly to it. The head of the ejector pin may be located out beyond bushing and may be dome-shaped, conical, or any of other various shapes. Alternately, the head of the ejector pin may be flush with bushing or may be recessed within the bushing.
    • 提供具有上表面和穿过其中的至少一个孔的模芯。 推模销设置在模芯中的至少一个孔内。 推出销包括具有突出在模芯上表面上的底切部分的衬套,用于增强模制在模芯上的部件的粘附。 衬套还具有横向穿过的孔,通过该孔通过顶销轴。 如果需要,包括头部的顶针轴将模具芯部附着在模芯上的部分推出。 衬套的突出部分以倒角的形式底切,圆周肋,凹进或突出,并且具有部分圆形或V形横截面,一系列凹坑或任何其它形状 这将导致模塑塑料紧紧地附着在其上。 顶针的头部可以位于衬套之外,并且可以是圆顶形,圆锥形或任何其它各种形状。 或者,推顶销的头部可以与衬套齐平或者可以凹入套管内。

A front member is pivotally connected to the base and is pivotable from a closed position toward a position in which the front member is substantially coplanar with the lower wall. A top member is pivotally connected to the base about a pivot axis which is substantially parallel to the pivot axis of the front member, and is pivotable from a closed position toward a position in which the top member is substantially coplanar with the rear wall. The case also includes a scabbard for being applied to the bar of the chainsaw, the scabbard having an end portion adapted to be received within the slot when the chainsaw is disposed within the base.
    • 提供了具有棒的电锯的电锯。 壳体包括具有下部,后部和两个端壁的底座,其中一个端壁在其中具有狭槽。 前部构件枢转地连接到基座并且可以从关闭位置朝向前部构件与下壁基本共面的位置枢转。 顶部构件围绕基本上平行于前部构件的枢转轴线的枢转轴线枢转地连接到基部,并且可以从关闭位置枢转到顶部构件与后壁基本共面的位置。 壳体还包括用于施加到电锯的杆上的刀鞘,当锯链设置在基座内时,刀鞘具有适于容纳在槽内的端部。
