Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold for demolding a slider insert knife. Background Art

[0002] In a continuous stamping die, it is necessary to convert the reciprocating motion of a punching press slider in the vertical direction into a horizontal direction motion to meet specific production requirements. Traditionally, the cooperation of an insert knife and a slider is commonly used to achieve the conversion of the force direction. Through the contact cooperation of the inclined surfaces of the two, the vertical direction motion of the insert knife is converted into the horizontal direction sliding of the slider.

[0003] The production method of the slider insert knife will vary according to its specific design and requirements. In addition to the traditional lathe cutting, milling, and grinding, die-casting molds are now more common. In addition to saving a large amount of time and labor, products that more meet the product specifications can be produced after simple surface treatment.

[0004] In the existing die-casting production molds, after the slider is produced, it is very difficult to take out the finished product from the mold cavity due to the small friction and large mass, which will greatly waste time. Moreover, after producing the slider, a large amount of time is required to replace the mold to produce the insert knife. For this reason, a mold for demolding a slider insert knife is proposed to solve the above problems. Summary of the Utility Model

[0032] Refer to Figures 1-5, an embodiment provided by the present utility model: a mold for demolding a slider 19 inserted knife, including a base 1, a mold groove 3 is opened inside the base 1, a lower mold 5 is arranged on the inner bottom wall of the mold groove 3, an outer box 8 is fixedly connected inside the base 1, a motor 10 is fixedly connected inside the outer box 8, the output end of the motor 10 is fixedly connected with a turntable 9, a rotating shaft 11 is fixedly connected to the left edge of the turntable 9, a limiting groove 13 is slidably connected to the outside of the rotating shaft 11, a top column 12 is fixedly connected to the top of the limiting groove 13, hydraulic support columns 4 are fixedly connected to the four corners of the top of the base 1, a top seat 2 is fixedly connected between the output ends of the four hydraulic support columns 4, a fixing table 7 is fixedly connected to the bottom of the top seat 2, an upper mold 6 is fixedly connected to the bottom of the fixing table 7, a convex block 15 is fixedly connected to the top end of the upper mold 6, a fixing component is arranged inside the fixing table 7, and the fixing component is used for fixing the upper mold 6. The outside of the limiting groove 13 is slidably connected to the inner wall of the outer box 8, the outside of the top column 12 is slidably connected inside the outer box 8, the outside of the top column 12 is slidably connected inside the lower mold 5, and the outside of the convex block 15 is slidably connected inside the fixing table 7.

[0033] Specifically, after the product is die-cast and formed, the motor 10 is started. The output end of the motor 10 drives the turntable 9 to rotate, and the rotating shaft 11 on the left side of the turntable 9 also rotates with the turntable 9 and slides inside the limiting groove 13. The limiting groove 13 slides upward inside the outer box 8 under the upward thrust of the rotating shaft 11. The top column 12 at the top of the limiting groove 13 also slides upward with the limiting groove 13. The top column 12 penetrates through the outer box 8 and the lower mold 5 to eject the formed product out of the lower mold 5. The turntable 9 continues to rotate, and the rotation of the rotating shaft 11 causes the limiting groove 13 to slide downward on the inner wall of the outer box 8 and drives the top column 12 back to its original position.

[0034] Refer to Figure 4-4 , the fixing component includes a card box 14, the card box 14 is fixedly connected to the inner wall of the fixing table 7, a first limiting column 16 is fixedly connected inside the card box 14, a spring 22 is sleeved on the outside of the first limiting column 16, a button 17 is slidably connected to the outside of the first limiting column 16, a rotating rod 18 is rotatably connected to the bottom of the outside of the button 17, a plug pin 20 is rotatably connected to the end of the rotating rod 18 away from the button 17, a slider 19 is fixedly connected to the outside of the plug pin 20, a second limiting column 21 is slidably connected inside the slider 19, one end of the spring 22 is fixedly connected to the right side of the button 17, the other end of the spring 22 is fixedly connected to the inner wall of the card box 14, the button 17 is slidably connected inside the card box 14, the plug pin 20 is slidably connected inside the card box 14, and the plug pin 20 is inserted between the convex block 15.

[0035] Specifically, before die-casting the product, appropriate upper and lower molds are selected. After the selection, the lower mold 5 is fixed inside the mold groove 3, and the upper mold 6 is fixed to the bottom of the fixing table 7 through the bump 15 at the top. Specifically, through the card box 14 inside the fixing table 7, the button 17 sliding inside the card box 14 is pressed. The button 17 slides on the first limiting post 16 and compresses the spring 22. A rotating rod 18 is arranged inside the card box 14. The rotating rod 18 is a telescopic column and the rotating rod 18 rotates inside the card box 14. The rotating rod 18 rotates and pulls the bolt 20 to the left. After the bump 15 is inserted into the groove inside the fixing table 7, the button 17 is released. The button 17 slides to the left under the action of the spring 22. At this time, the rotating rod 18 gives the bolt 20 a force to the right. The bolt 20 penetrates the fixing table 7 and inserts into the inside of the bump 15, completing the fixation between the upper mold 6 and the fixing table 7.

[0036] Working principle: In mold production, first, the hydraulic support column 4 is started to move downward. A fixing table 7 is fixedly connected to the bottom of the top seat 2. Inside the fixing table 7, there is a card box 14. Inside the card box 14, there are a button 17 and a bolt 20. The button 17 is pressed to make it slide on the first limiting post 16 and compress the spring 22 inward. The rotating rod 18 rotates and pulls the bolt 20 to the left, and the slider 19 on one side of the bolt 20 slides on the second limiting post 21. At this time, the fixing component is in a non-fixed state. After the bump 15 at the top of the upper mold 6 is inserted into the inside of the fixing table 7, the button 17 is released. Under the action of the spring 22, the button 17 is pushed outward, driving the rotating rod 18 to rotate and pushing the bolt 20 to the right. The bolt 20 is inserted into the preset holes inside the fixing table 7 and the bump 15. The upper mold 6 slides on the inner wall of the lower mold 5, and a closed mold cavity is formed between the upper mold 6 and the lower mold 5. At this time, the molten metal is injected into the cavity through the injection system of the mold. After a period of time for pressure holding, circulating cooling liquid is injected inside the mold groove 3 and waiting for the molten metal to cool and form. The hydraulic support column 4 is started, and the top seat 2 moves upward. At this time, the motor 10 inside the base 1 is started. The output end of the motor 10 drives the turntable 9 to rotate. The rotating shaft 11 on the turntable 9 rotates with the turntable 9 and slides inside the limiting groove 13. The limiting groove 13 slides upward on the inner wall of the outer box 8 under the upward force of the rotating shaft 11. The ejector pin 12 slides upward and jacks up the formed product inside the lower mold 5. The product is ejected from the mold groove 3 for easy removal.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
