With reference to fig. 1 to 4, the present embodiment provides an inclined strut, which includes a top member 10 and a matching portion 101, where the matching portion 101 is fixedly connected to the top member 10, the top member 10 includes a first inclined surface 102 and a limiting portion 103, the limiting portion 103 and the first inclined surface 102 are respectively disposed on different sides of the top member 10, and a hinge portion is disposed on the top member 10.

The inclined strut can be arranged in an ejection area of a die which is limited in space and cannot use a sliding block and an inclined top, and the inclined strut swings by utilizing the hinged connection of the hinged part and the die structure so as to replace an elastic ejection mechanism or a ball head connection ejection mechanism and synchronously complete ejection and unhooking of a die forming product. For example in the processing of the big panel product of air outlet, to the inside back-off structure of the big panel product of air outlet, because the limitation of mould inner space, can't use slider and pitched roof, consequently can use the bracing of this embodiment, utilize the self structural feature of bracing, when the liftout 10 goes up and down along with the mould promptly, can take place for the rotation of mould, the structural feature of cooperation liftout 10, when realizing that the big panel product of air outlet is ejecting, accomplish the unhook of liftout 10 and the inside back-off structure of the big panel product of air outlet in step.

The inclined strut is hinged to the die through the hinged portion, can replace a traditional elastic ejection structure and a ball head connection ejection mechanism, adopts materials with lower cost, such as common steel, and further reduces the processing and assembling cost and the later maintenance cost on the basis that the functions can be replaced completely.

In this embodiment, the top part 10 in the inclined strut is hinged to the structure in the mold, and the top part 10 can be directly or indirectly driven by the top plate of the mold, so as to move up and down along with the top plate, and due to the hinged cooperation of the structure in the movable top part 10 and the mold, the structure of the top part 10 is matched, so that the top part can contact with the mold core and rotate while the up and down movement is realized.

The top part 10 comprises a matching part 101 arranged at the end part, the shape of the matching part 101 is matched with that of a mold forming product, and on one hand, the top part is used for forming a product cavity together with a mold core in a mold forming stage for forming the product; on the other hand, the matching part 101 and the product form a barb-shaped matching, so that the ejector 10 and the product are firmly combined in the ejection stage of the product, and further stable ejection of the product is realized.

The ejector 10 further comprises a first inclined surface 102, the first inclined surface 102 can be matched with an inclined surface on the mold core, the inclined angle of the first inclined surface 102 is the same as that of the inclined surface on the mold core, when the inclined strut ascends along with the top plate, the first inclined surface 102 is contacted and attached with the inclined surface on the mold core, along with the ascending of the ejector 10, the ejector 10 rotates by a certain angle, and because a gap exists between a product and a matching part of the ejector 10, the barb-shaped matching between the ejector 10 and the product can be gradually released along with the ejection of the product.

The top piece 10 further includes a first inclined surface 102 and a limiting portion 103, in this embodiment, the limiting portion 103 is a horizontal shoulder on the top piece 10, and the limiting portion 103 can limit the stroke of the top piece 10 after abutting against the mold core. The purpose of stroke limitation of the top member 10 by the limiting portion 103 is: because the mould size is limited, can prevent the upstroke of ejecting 10 through setting up spacing portion 103, when having avoided ejecting 10 to drive the product to go up, the product top offsets with the mould and takes place to strike, and then damages product and ejecting 10 self.

Further, because the existence of spacing portion 103, make the extension size of top 10 shorter, the intensity of top 10 extension has been promoted to a certain extent, because the fitting piece 101 of top 10 tip is used for supporting the product, and the product focus does not necessarily fall in the within range of top 10, consequently, can make top 10 inevitably take place the bending of certain degree, shorter extension size can provide higher intensity in order to overcome the bending, prolong the life of top 10, also can avoid causing dropping of product because of the bending of top 10, and then damage the product, improve the yields of product.

As an alternative embodiment of this embodiment, the bottom of the top 10 is provided with a flat part 104. Through set up plane portion 104 in top 10 bottom, can prevent that the bracing in this embodiment from taking place to empty when carrying out the product and moulding plastics for top 10 can keep vertical ascending state all the time when the product is moulded plastics, has promoted the stability of bracing when using.

As an alternative embodiment of this embodiment, the bottom of the top piece 10 is provided with a matching part 105. The matching part 105 can be only arranged at one side of the bottom of the top part 10 close to the inclined strut toppling direction, the shape of the matching part 105 can be an inclined plane or an arc surface, and can also be set to be a chamfer or a fillet at the bottom of the top part 10, and through the arrangement of the matching part 105, the top part 10 can smoothly rotate and does not interfere with the fixing part 20.

As an optional implementation manner of this embodiment, the limiting portion 103 is a plane that is disposed on the top member 10 and perpendicular to the length direction of the top member 10.
