Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model discloses an ejection mechanism looses core to one side of slider, as shown in fig. 1-5, including cover half 1, movable mould 2 and left slider 3 and the right slider 4 of setting on cover half 1, form the pouring chamber behind movable mould 2, cover half 1, left slider 3 and the 4 locks of right slider, then pour into a mould. An inclined guide post 21 is arranged on the movable die 2, a guide groove 5 is arranged at the corresponding position of the left slide block 3 and the right slide block 4, and when the movable die 2 is driven to move upwards, the inclined guide post 21 arranged on the movable die 2 drives the left slide block 3 to move leftwards and the right slide block 4 to move rightwards. At this time, the side edge of the product may be stretched to both sides following the left slider 3 and the right slider 4, causing deformation of the product. Therefore, the left slider 3 and the right slider 4 are respectively provided with a mounting groove 6 for mounting the thimble mechanism, the thimble mechanism 7 is mounted in the mounting groove 6, and when the left slider 3 and the right slider 4 move to both sides, the thimble mechanism 7 applies thrust to both sides of the product to prevent the product from stretching to both sides along with the product.

Specifically, the thimble mechanism 7 includes a first elastic member 71 and a slider thimble 72, the first elastic member 71 is disposed in the mounting groove 6, the slider thimble 72 penetrates through the first elastic member 71 and penetrates through the slider, the first elastic member 71 may be a spring, and the spring pushes the slider thimble 72 to move toward an end away from the product. The other end of the movable mould is contacted with the movable mould 2, and the vertical side 22 is arranged at the corresponding position of the movable mould 2, so that the movable mould 2 is always attached to the slide block thimble 72 by a section of stroke to keep the slide block thimble 72 still in the process of moving the movable mould upwards. Preferably, in order to prevent the slide ejector pin 72 from being ejected out of the mounting groove 6 after being disengaged from the movable mold 2, the wear-resistant blocks 8 are respectively provided on the left slide 3 and the right slide 4, and one end of the slide ejector pin 72 protrudes out of the wear-resistant block 8. The wear block 8 is used to limit the maximum position of movement of the wear pin 72. In addition, in the mold closing state, the slider thimble 72 and the side wall of the slider are on the same plane to ensure that the casting cavity is matched with the shape of the product.

In one embodiment, when the left slider 3 and the right slider 4 move towards two sides, the sliders may slide out of the fixed mold 1, and therefore, the two sides of the fixed mold 1 are provided with the limiting blocks 9 for limiting the sliding range of the sliders. Taking the left slider 3 as an example, when the left slider 3 is driven by the inclined guide post 21 to move leftwards, the movable mold 2 moves upwards to separate the inclined guide post 21 from the guide groove 5, and the left slider 3 may continue to move leftwards due to inertia or other external factors, causing position deviation, and even directly sliding out of the fixed mold 1. The right slider 4, like the left slider 3, also suffers from the above-mentioned problems. Through setting up stopper 9, can restrict the displacement range of slider, prevent above-mentioned condition.

In one embodiment, the fixed mold 1 is provided with restraining devices 10 at both sides thereof for preventing the left slider 3 and the right slider 4 from freely moving, i.e. moving themselves in case the left slider 3 or the right slider 4 is stationary. As shown in fig. 1, there is an oblique sliding surface between the right slider 4 and the fixed mold 1, because the right slider 4 may slide along the oblique surface toward the product without external force, when the mold is closed, the oblique guide post 21 does not correspond to the guide slot 5, and the oblique guide post 21 directly presses on the right slider 4, causing damage to the oblique guide post 21. Specifically, the constraint device 10 includes a second elastic member 101 and a connecting rod 102, for example, the right slider 4, one end of the connecting rod 102 is connected to the right slider 4, and the other end is connected to the second elastic member 101, and the second elastic member 101 may be a spring, which is fixed to the fixed mold 1, or may also be fixed to the stopper 9, and the connecting rod 102 is applied with a pulling force through the spring. The left slider 3 is the same as the previous embodiment, the spring always applies a force to the connecting rod 102 opposite to the direction of movement of the slider itself. The spring force is only required to ensure that the slide does not move freely and is not pushed by the spring force.

In one embodiment, a gap is formed between the guide groove 5 and the inclined guide post 21, so that the movable mold 2 moves for a section of idle stroke when moving upwards, the left slide block 3 and the right slide block 4 cannot be driven to move towards two sides, the upper part is separated from a product firstly, and the product demolding quality is guaranteed.

In one embodiment, three ejector pin mechanisms 7 are respectively arranged on the left sliding block 3 and the right sliding block 4, and are respectively arranged up and down to apply pressure to the whole side surface of the product. Of course, the thimble mechanisms 7 can be increased or decreased according to the actual demand of the product.

When the utility model is used, as shown in fig. 1-5, fig. 1 shows a state diagram before demoulding, the movable mould 2 moves upwards, the inclined guide post 21 and the guide groove 5 move to one side far away from the product from one side near the product, the movable mould 2 is separated from the product, the thick left slider 3 and the thick right slider 4 move towards two sides under the action of the inclined guide post 21, at the moment, as shown in fig. 2, the left slider 3 and the right slider 4 are separated from the product, but the slider thimble 72 always pushes against the product; specifically, taking the right slider 4 as an example, the moving die 2 moves upward to drive the right slider 4 to move rightward, at this time, due to the action of the vertical edge 22, the vertical edge 22 always pushes against the slider thimble 72, the slider thimble 72 remains stationary, the first elastic member 71 is compressed, and when one end of the slider thimble 72 is separated from the vertical edge 22, the slider thimble 72 moves rightward by the elastic force of the first elastic member 71 to return to the initial position; as shown in fig. 3, when the guide groove 5 of the right slider 4 is separated from the inclined guide post 21, the right slider 4 is kept stationary by the stopper 9 and the restraint device 10, and can be matched with the inclined guide post 21 during mold clamping. During mold closing, the movable mold 2 moves downwards, the inclined guide post 21 moves into the guide groove 5, the left side of the inclined guide post 21 acts on the left side of the guide groove 5, and the right slide block 4 is pushed to move leftwards as shown in fig. 4 until mold closing is carried out, and the position shown in fig. 5 is reached. The action process of the left slider 3 is the same as that of the right slider 4, and is not described in detail herein.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
