Description
Technical field
The utility model relates to moulding machine accessory technical field, particularly the anti-down mechanism of a kind of Novel limiting.
Background technology
Mould conveyer is the prevailing traffic equipment contacting the operations such as moulding, foundary weight, cast, knockout in moulding machine production line, transport trolley is the bearing part of conveyer, can the whether accurate operations such as moulding machine production line foundary weight, cast, knockout that are directly connected to of location, transport trolley position complete smoothly, and spacing anti-down mechanism ensures one of key mechanism of transport trolley position location just.
Owing to there is many unreasonable parts in structural design in existing spacing anti-down mechanism, cause mainly there is following problem in the course of the work: in order to prevent the rotation of limit shaft, limit shaft head is processed into square structure, the end cap that limit shaft passes also is processed into square structure, utilize the square hole of end cap to prevent the rotation of limit shaft, limit shaft and end cap processing technology complexity will certainly be caused like this; The square structure of limit shaft head, whole mechanism is made to be difficult to realize sealing, dust ring cannot mounting arrangements, therefore in the process of limit shaft work, sand grains easily enters spacing anti-down mechanism, cause the wearing and tearing of limit shaft and stuck, reduce the service life of parts on the one hand, cause whole position-limit mechanism to lose spacing and anti-down function on the other hand; Also there is rigidity deficiency in the structure of bearing itself, and its open structure makes outside sand grains, dust etc. easily enter spacing anti-down mechanism, limit shaft also can be caused to move not smooth, cause the inefficacy of body function.
Utility model content
For solving problems of the prior art, the utility model provides a kind of spacing anti-down mechanism of Novel horizontal parting and removable flask shoot and squeeze molding machine.
The purpose of this utility model carrys out specific implementation by the following technical programs:
A kind of anti-down mechanism of Novel limiting, comprise bearing, in described bearing, be provided with limit shaft, described limit shaft is arranged with spring, in bearing one end, be provided with the end cap with through hole, described limit shaft through described end cap through described through hole, is provided with anti-rotation end cap at the described bearing other end, described anti-rotation end cap is provided with anti-rotation bayonet socket, described limit shaft is provided with anti-rotation face, described anti-rotation bayonet socket matches with anti-rotation face
Further, described end cap is provided with groove, in described groove, is provided with dust ring.
Further, described through hole is circular hole.
Further, in described bearing, copper sheathing is provided with.
Further, described copper sheathing is two, is separately positioned on two ends inside described bearing, and described copper sheathing is self-lubricating copper sheathing.
The beneficial effects of the utility model are:
1, the anti-down mechanism of a kind of Novel limiting disclosed in the utility model, by the application of anti-rotation end cap, makes the parts such as limit shaft, end cap get final product content with funtion by common shape, and whole mechanism structure is more simple, and processing technology is better;
2, the anti-down mechanism of a kind of Novel limiting disclosed in the utility model, by installing dust ring on end cap, the sealing property of whole mechanism is strengthened greatly, decrease the possibility of the wearing and tearing such as limit shaft, and the structure closed also prevent entering of external dust, sand grains etc., protects the parts such as limit shaft, spring; Extend the service life of parts;
3, the anti-down mechanism of a kind of Novel limiting disclosed in the utility model, greatly strengthen guiding and the kinematic accuracy of limit shaft by the installation of self-lubricating copper sheathing, makes the motion of limit shaft more reliably smooth and easy;
4, the anti-down mechanism of a kind of Novel limiting disclosed in the utility model, simple and reasonable, design, manufacture, easy for installation, reliability is higher, reduce processing and maintenance cost.

Detailed description of the invention
As shown in the figure, the spacing anti-down mechanism of a kind of horizontal parting slip flask shoot-squeeze moulding machine described in the utility model, comprise end cap 2, bearing 3, limit shaft 1, anti-rotation end cap 6, spring 4, copper sheathing 5, bearing 3 is hollow cavity, limit shaft 1 is provided with in bearing 3, described limit shaft 1 is arranged with spring 4, in bearing 3 one end, be provided with the end cap 2 with through hole, described limit shaft 1 passes described end cap 2 through described through hole, described bearing 3 other end is provided with anti-rotation end cap 6, described anti-rotation end cap 6 is provided with anti-rotation bayonet socket 9, described limit shaft 1 is provided with anti-rotation face 8, described limit shaft 1 passes anti-rotation end cap 6 by anti-rotation bayonet socket 9, described anti-rotation bayonet socket 9 matches with anti-rotation face 8.
Concrete, limit shaft 1 entirety is stepped cylindrical, on limit shaft 1 surface of anti-rotation bearing correspondence position, centrally axial symmetry is arranged with two anti-rotation faces 8 in parallel, simultaneously, on bearing 3, be provided with the anti-rotation bayonet socket 9 that can cooperatively interact with anti-rotation face 8, being cooperatively interacted by anti-rotation face 8 and anti-rotation bayonet socket 9 prevents the rotation of limit shaft 1; Meanwhile, the circular hole hole wall on end cap 2 increasing the groove for installing dust ring 7, utilizing dust ring 7 to enter position-limit mechanism inside to prevent sand grains etc. from end cap 2; In bearing 3 chamber, respectively a self-lubricating copper sheathing 5 is installed up and down, increases guiding when limit shaft 1 is moved.
A kind of spacing anti-down mechanism newly that the utility model relates to, hinge structure structure is more simple, and the processing technology of parts simplifies more, and the guidance quality of whole mechanism seals and motion strengthens, decrease and wearing and tearing and stuck possibility occur, the operation of whole mechanism is more steadily reliable.
