In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
First embodiment
Referring to fig. 1 and fig. 2 in combination, an embodiment of the present invention provides a combined bi-directional side-pumping mechanism 100 for core-pulling molding a product 500. The structure size can be reduced on the premise that core pulling operations in two different directions are guaranteed to be carried out normally, the processing cost is reduced, the stability of core pulling movement is enhanced, and the quality of the product 500 is improved. In this embodiment, the combined bidirectional side-pulling mechanism 100 is used for pulling cores of two ribs with different extending directions on the air duct product 500 of the air conditioner, and the extending directions of the two ribs are opposite, but not limited thereto, and in other embodiments, the extending directions of the two ribs on the product 500 may be inclined and may also be perpendicular.
The combined bidirectional side-pulling mechanism 100 comprises a fixed die plate 110, a fixed die core 120, an inclined top pressing block 130, an elastic piece 140, an inclined top 150, a shovel base 160, an inclined guide post 170, a sliding block 180, a movable die plate 190, a limiter 200, a pressing strip 210 and a guide strip 220. The fixed platen 110 is attached to the movable platen 190, and the movable platen 190 moves away from the fixed platen 110 during mold opening. The fixed mold insert 120 is fixedly installed in the fixed mold plate 110, and the fixed mold insert 120 is used for molding the product 500. The inclined top pressing block 130 is fixedly connected with the fixed die plate 110 and is connected with the inclined top 150 through the elastic piece 140, the elastic piece 140 is always in a compressed state, and the elastic piece 140 can provide elastic force for the inclined top 150 when the die is opened so as to push the inclined top 150 to move in a direction away from the inclined top pressing block 130. The fixed die core 120 is provided with the sliding groove 121, the inclined top 150 is arranged in the sliding groove 121 in a sliding manner, the sliding groove 121 can limit the movement direction of the inclined top 150, the inclined top 150 can only slide along the preset direction, and core pulling operation of the product 500 is achieved. In the present embodiment, the elastic member 140 is a spring, but not limited thereto, and in other embodiments, the elastic member 140 may be elastic rubber.
In this embodiment, the limiter 200 is mounted on the movable platen 190, and the limiter 200 can limit the limit position of the slide 180, prevent the slide 180 from being separated from the movable platen 190, and prevent the slide 180 from moving accidentally without starting mold clamping. The pressing bar 210 is installed on the movable mold plate 190, and the pressing bar 210 is used for pressing the sliding block 180 on the movable mold plate 190, so that the sliding block 180 can only be attached to the movable mold plate 190 to slide, and the sliding block 180 is prevented from tilting or turning over. The guide bar 220 is mounted on the movable mold plate 190, and the guide bar 220 is adapted to slidably cooperate with the slider 180 to define a movement direction of the slider 180 such that the slider 180 can only slide in the first direction.
Referring to fig. 3, 4, 5, 6 and 7, it should be noted that the shovel base 160 is fixedly mounted on the fixed platen 110 and fixedly connected with the inclined guide post 170, the inclined guide post 170 extends into the slider 180 and is slidably engaged with the slider 180, and the inclined guide post 170 can limit the movement direction of the slider 180, so that the slider 180 can only slide along the first direction. The sliding block 180 abuts against the inclined top 150 and is in sliding fit with the movable template 190, and the sliding block 180 is arranged on the movable template 190 in a sliding manner. The slide block 180 can core-pull the product 500 along the first direction under the action of the oblique guide pillar 170 during mold opening, and the oblique top 150 can core-pull the product 500 along the second direction under the action of the elastic member 140 during mold opening. In this embodiment, the first direction and the second direction are opposite, that is, core pulling operation is implemented for two ribs with opposite extending directions. Specifically, the mold opening direction is the vertical direction, i.e., the movable platen 190 is away from the fixed platen 110 in the vertical direction; the first direction and the second direction are both horizontal directions, and the first direction is a direction away from the product 500, and the second direction is a direction close to the product 500.
It should be noted that, during mold opening, the movable mold plate 190 moves in a direction away from the fixed mold plate 110, at this time, the movable mold plate 190 is used as a reference, the inclined guide post 170 and the shovel base 160 are driven by the fixed mold plate 110 to move away from the movable mold plate 190, the inclined guide post 170 drives the slide block 180 to slide along the first direction relative to the movable mold plate 190, so as to core-pull the product 500 in the first direction, and the slide block 180 moves away from the fixed mold plate 110 along with the movable mold plate 190, and because the inclined top 150 abuts against the slide block 180, the inclined top 150 pops outwards under the action of the elastic member 140 and moves along the preset direction in order to core-pull the product 500 in the second direction, and finally the slide block 180 is separated from the inclined top 150, so as to complete core-pulling operation.
It is noted that, the preset direction is set at a preset included angle with the second direction, in the process that the inclined top 150 moves along the preset direction, the inclined top 150 is subjected to movement analysis, the preset direction is decomposed into the second direction and the vertical direction, and since the movable mold plate 190 is far away from the fixed mold plate 110 along the vertical direction, the sliding block 180 abuts against the inclined top 150, and the product 500 moves along with the movable mold plate 190, the movement speed of the inclined top 150 in the vertical direction during mold opening is equal to the movement speed of the product 500 in the vertical direction, the inclined top 150 and the product 500 remain relatively stationary in the vertical direction, and the inclined top 150 moves relative to the product 500 in the second direction, i.e. the function of pulling the core of the product 500 in the second direction is realized. For ease of understanding, the preset direction is denoted as fpre, the first direction as F1, the second direction as F2, and the vertical direction as fvertical.
Specifically, the preset included angle ranges from 0 degrees to 90 degrees, in this embodiment, the preset included angle is 75 degrees, but is not limited thereto, and in other embodiments, the preset included angle may be 30 degrees or 60 degrees, and needs to be determined according to the specific situation of the product 500.

One end of the elastic member 140 abuts against the guide block 152, the other end abuts against the inclined pressing block 130, and the elastic member 140 can apply elastic force to the guide block 152. The guide block 152 abuts against the slide block 180, and the slide block 180 can limit the guide block 152, so that the sliding speed of the guide block 152 in the vertical direction is limited to be the same as the die opening speed. The inclined top body 151 slides and sets up in spout 121, and the guide block 152 slides and sets up in guide slot 122, and guide slot 122 can carry out spacingly to the guide block 152 for the guide block 152 can only slide along the direction of predetermineeing, thereby guarantees that inclined top body 151 slides along the direction of predetermineeing, and then accomplishes the operation of loosing core to product 500.
