The invention provides a mold locking device and a mold, and relates to the technical field of casting. The mold locking device comprises a guide sleeve and a locking seat, wherein an unlocking grooveis formed in the cavity bottom of an inner cavity of the guide sleeve, the locking seat is provided with an axial through hole, and a guide rod is elastically installed in the axial through hole; thetop of the locking seat is provided with a first inserting end matched with the inner cavity in an inserted mode, and the top of the guide rod is provided with a second inserting end matched with theunlocking groove in an inserted mode; limiting holed communicating with the axial through hole are formed in the side wall of the first inserting end, and limiting balls are movably assembled betweenthe side wall of the guide rod and the limiting holes; and the second inserting end is wedge-shaped, and limiting grooves corresponding to the limiting holes are formed in the side cavity wall of theinner cavity. According to the technical scheme, when an upper template and a lower template carry out mold locking by any number of the locking devices, due to the fact that the locking state of each locking device is consistent, each position of the upper template and the lower template can be guaranteed to be uniformly locked, the problem that the upper template is offset relative to the lowertemplate is solved, and the locking quality is guaranteed.

The present invention is used for the technical field of aviation engine vane non-destructive testing, especially relates to a positioning fixture for guide vane detection which performs wall thickness detection through industrial CT. A guide vane is generally complex in shape, and installation sides of the guide vane are irregular and have complex curved surfaces, so that it is not easy to achieve accurate positioning of coordinate axes to obtain a section position required by industrial CT scanning. A bottom plate is provided with a vertical plate, a second positioning block, a third positioning block and a compressing block pedestal, wherein the second positioning block and the compressing block pedestal are arranged at two sides of the vertical plate, a compressing block is slidingly connected with the compressing block pedestal, a screw passes through the second positioning block, the vertical plate and the compressing block, and the screw and screw threads in the compressing block form a lead screw pair; and the position of the compressing block is regulated through rotation of the screw to clamp the guide vane. The positioning fixture for guide vane detection achieves positioning of the coordinate axes of the guide vane so as to accurately locate the industrial CT detection section.

The invention provides a high pressure turbine guide vane chord width measuring clamp tool comprising a base plate, a support seat is fixed on the base plate, a pressing head is vertically mounted on the support seat and is used for tightly pressing a vane in a vertical direction, a first measurement device and a second measurement device are mounted on the base plate, the first measurement device comprises a fixed device, a first groove used for erecting a first digital display caliper is arranged on the fixed device, the second measurement device is a measurement seat, and the measurement seat is provided with a second groove used for erecting a second digital display caliper. The vane is first tightly pressed in the vertical direction via the pressing head on the support seat on the base plate, and the vane is positioned and fixed via the fixed device on the first measurement device. Artificial interference factors of a hand held vane can be eliminated via a fixed structure. Then parts such as the first measurement device, the second measurement device and the like are used for switching a vane measurement basis from the vane to measurement parts, and the basis is enabled to be stable and accurate. The measuring tool can be used repeated, a large batch of vanes can be measured and inspected, vane measuring and inspecting efficiency can be greatly improved, false inspection and missed inspection can be basically eliminated, and reference can be provided for future design of engine vanes of the same kind.

A device for punching a valve casing seal chamfer comprises a base, a location pin for centering the valve casing is arranged on the base, a steel ball for punching is arranged at the position of the valve casing seal chamfer, and a valve ejection rod simulation part is connected with the upper portion of the steel ball. A cylindrical movable punching element is mounted on the upper portion of the valve ejection rod simulation part through a travel support, and the tail of the movable punching element is connected with a cylindrical counter weight through a screw and nut component. The movable punching element falls vertically to punch the valve ejection rod simulation part to enable the steel ball to punch the valve casing to obtain the seal chamfer. According to the device, the speed and the quality of the movable punching element during punching are fixed, so that quantity control can be performed on the punching process, the machining position is accurate through the location pin and the travel support, the chamfer deformation is uniform, one-step shaping is formed, the joint seal meets requirement, and the product quality is improved; the device is novel in structure, practical and safe and reliable; the problem of smoking of turbine power generation devices is solved.
