Description

Technical field

[0001] The invention relates to the technical field of mold mechanisms, in particular to a combined slider core-pulling mechanism. [Background Technology]

[0002] In the laptop computer parts, the oblique BOSS (column position, that is, the cylinder on the product) design has been widely used. A single product can no longer meet the needs of the personalized era, which also puts forward more flexible requirements for the mold structure, so the designed mold structure is required to be more sophisticated, strong and durable.

[0003] like Figures 1-2 The product 20 shown has a column position 30 structure with an inclination. Generally, the mold design requires setting a slider exit mechanism in the inclination direction of the column position 30 and the side direction of the undercut 40 respectively, which leads to problems such as mold jamming and easy breakage of the inclined core when the product 20 is exited after molding.

[0004] In view of this, it is necessary to provide a combined slider core-pulling mechanism to solve the above problems. [Summary of the invention]

[0005] The technical problem addressed by this invention is that, in a product with a sloped column structure, conventional mold designs require separate slider withdrawal mechanisms for the column slope and the undercut side. This can lead to mold jamming and easy breakage of the inclined core during product ejection after molding. Therefore, this invention provides a combined slider core-pulling mechanism to address this issue.

[0006] The present invention solves the technical problem by providing a combined slider core-pulling mechanism comprising:

[0007] The slider seat is fixedly connected to the first slider in the slider seat. The first slider is used to form the side end of the product and is undercut. When the mold is opened, the first slider is removed from the side end of the product under the action of the slider seat. The slider seat is fixedly connected to the connecting block on the side away from the mother mold core.

[0008] The second slider is provided with an oblique groove and a groove, the oblique groove cooperates with the oblique guide block of the movable block for guiding the movable block when the movable block moves, the groove cooperates with the connecting block and is fixedly connected, and is used to make the slider seat drive the second slider to move through the cooperation of the connecting block and the groove when the mold is opened and exited. The side wall of the second slider is provided with a slide groove, and a fixed block is provided in the slide groove. The fixed block is fixedly connected to the mold through a fixing piece. The fixed block is used to fix the second slider and guide it when it moves. The bottom of the second slider is provided with a bottom wear-resistant plate, which is fixed in the mold. It is used to increase the hardness and wear resistance of the mold, thereby improving the service life of the mold;

[0009] The movable block is connected to the inclined core seat through a buckling structure, thereby driving the inclined core seat to slide in the inclined groove. The movable block is provided with an inclined guide block on the side in contact with the second slider, and the inclined guide block is used to cooperate with the oblique groove of the second slider. When the second slider moves under the action of the slider seat, the movable block drives the oblique core seat fixedly connected thereto to drive the oblique core to move downward along the oblique groove of the second slider;

[0010] The female mold core and the male mold core cooperate to form the product.

[0011] Preferably, the fixing member includes but is not limited to a screw.

[0012] Preferably, the oblique groove is a "T"-shaped groove, and the oblique guide block is a "T"-shaped block, and the cooperation between the two is used to ensure stable movement of the movable block.

[0013] The beneficial effect of the present invention is that the present invention uses a combined slider core pulling mechanism, which drives the first slider and the second slider to move through the slider seat, so that the side end of the first slider exiting the product is inverted, and at the same time, the inclined groove on the second slider cooperates with the inclined guide block to move the movable block downward, and then the movable block drives the inclined core on the inclined core seat to move together into the inclined hole of the exit product, thereby completing the demolding of the product. This mechanism effectively prevents the problems of mold jamming and easy breakage of the inclined core, and its structure is simple, stable and reliable.

[0020] To further illustrate the technical means and effects of the present invention, the following is a detailed description in conjunction with the embodiments of the present invention and the accompanying drawings.

[0021] The present invention provides a combined slider core-pulling mechanism, comprising:

[0022] The slider seat 110 has a first slider 111 fixedly connected therein. The first slider 111 is used to form the side undercut 21 of the product 20. When the mold is opened, the first slider 111 is moved out of the side undercut 21 of the product 20 under the action of the slider seat 110. The slider seat 110 is fixedly connected to the connecting block 112 on the side away from the female mold core 140.

[0023] The second slider 120 is provided with an oblique groove 121 and a groove 122 on the second slider 120. The oblique groove 121 cooperates with the oblique guide block 137 of the movable block 133 to guide the movable block 133 when it moves. The groove 122 cooperates with the connecting block 112 to be fixedly connected, so that when the slider seat 110 is opened and exited, the second slider 120 is driven to move by the cooperation between the connecting block 112 and the groove 122. The side wall of the second slider 120 is provided with a slide groove 123, and a fixed block 124 is provided in the slide groove 123. The fixed block 124 is fixedly connected to the male mold core 130 through a fixing member 150. The fixed block 124 is used to fix the second slider 120 and guide it when it moves. A bottom wear-resistant plate 125 is provided at the bottom of the second slider 120. The bottom wear-resistant plate 125 is fixed in the mold, which is used to increase the hardness and wear resistance of the mold, thereby improving the service life of the mold;

[0024] The male mold core 130 is fixedly connected to the guide block 131 in the male mold core 130. The guide block 131 is provided with an oblique groove 138. The oblique groove 138 is provided with an oblique core seat 132 and a movable block 133. The oblique core seat 132 is provided with a movable groove 134. The movable groove 134 is movably connected with an oblique core 135. The oblique core 135 is contoured with the oblique hole 22 of the product 20 at one end away from the oblique core seat 132. It is used to form the oblique hole 22 of the product 20. The movable groove 134 is used to prevent the oblique core 135 from being assembled with the oblique core seat 132 when the oblique core 135 exits the oblique hole 22 of the product 20. The installation gap causes the inclined core 135 to get stuck, and the movable block 133 is connected to the inclined core seat 132 through the buckling structure 136, thereby driving the inclined core seat 132 to slide in the inclined groove 138. The movable block 133 is provided with an inclined guide block 137 on the side in contact with the second slider 120. The inclined guide block 137 is used to cooperate with the inclined groove 121 of the second slider 120. When the second slider 120 moves under the action of the slider seat 110, the movable block 133 drives the inclined core seat 132 fixedly connected thereto to drive the inclined core 135 to move downward along the inclined groove 121 of the second slider 120;

[0025] The female mold core 140 cooperates with the male mold core 130 to form the product 20 .

[0026] The fixing member 150 includes but is not limited to a screw.

[0027] The oblique groove 121 is a T-shaped groove, and the oblique guide block 137 is a T-shaped block. The cooperation between the two is used to ensure the stable movement of the movable block 133.

[0028] The working process of the present invention is as follows: when the mold opening slider seat 110 retreats, the slider seat 110 drives the first slider 111 to move to the side end undercut 21 of the exit product 20, and at the same time, the connecting block 112 fixed on the slider seat 110 drives the second slider 120 to move together, and the inclined groove 121 on the second slider 120 cooperates with the inclined guide block 137 to make the movable block 133 move downward, and the movable block 133 drives the inclined core seat 132 fixedly connected to it to move in the inclined groove 138 of the guide block 131, thereby allowing the inclined core seat 132 to drive the inclined core 135 therein to move together to the inclined hole 22 of the exit product 20, thereby completing the demolding work of the product 20.

[0029] The beneficial effect of the present invention is that the present invention uses a combined slider core-pulling mechanism, which drives the first slider 111 and the second slider 120 to move through the slider seat 110, so that the first slider 111 exits the side end undercut 21 of the product 20, and at the same time, the inclined groove 121 on the second slider 120 cooperates with the inclined guide block 137 to move the movable block 133 downward, and then the movable block 133 drives the inclined core 135 on the inclined core seat 132 to move together to the inclined hole 22 of the product 20, thereby completing the demolding of the product 20. This mechanism effectively prevents the mold from getting stuck and the inclined core 135 from being easily broken, and its structure is simple, stable and reliable.

[0030] It should be pointed out that the present invention is not limited to the above-mentioned implementation mode, and any simple modification, equivalent change and modification made to the above-mentioned embodiment based on the technical solution of the present invention by any technician familiar with the profession shall fall within the protection scope of the present invention.
