Description

[Technical Field]

[0001] This invention relates to the field of mold mechanism technology, and in particular to a combined slider core-pulling mechanism. [Background Technology]

[0002] like Figure 1 The product 20 shown has a side end structure 30, which is a straight surface and does not allow for drafting. It is usually formed by a slider. When a general slider is used for forming, the ribs 40 of the side end structure 30 are prone to sticking to the slider, causing the product 20 to be stretched and deformed, which affects the yield of the product 20.

[0003] In view of this, it is necessary to provide a combined slider core-pulling mechanism to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is that the side structure of a product is straight, allowing for draft molding. While slider molding is commonly used, the ribs on the side structure tend to stick to the slider, causing product deformation and affecting yield. Therefore, this invention provides a combined slider core-pulling mechanism to address this problem.

[0005] The solution to the technical problem of this invention is: a combined slider core-pulling mechanism, comprising:

[0006] The mother mold has a mother mold core inside, and a push block is fixedly connected inside the mother mold core. The push block has a first inclined block and a second inclined block. A shovel base is provided on the side of the push block away from the product. The shovel base is fixedly connected inside the mother mold. The side of the shovel base that contacts the core-pulling seat has a first inclined surface, a first straight surface and a second inclined surface.

[0007] The mold has a core, within which a slider is slidably connected. The side of the slider that contacts the product is modeled after the side structure of the product, used to mold the side structure of the product. The slider has a movable groove, within which a slider insert is slidably mounted. The side of the slider insert that contacts the product is modeled after the ribs of the product, used to mold the ribs of the product. The end of the slider insert away from the product is fixedly connected to a slider seat, which is slidably positioned within the movable groove. A third inclined block is located on the side of the slider seat that contacts a push block. The third inclined block cooperates with a first inclined block to push the slider seat away from the ribs of the product's side structure during mold opening. The third inclined block cooperates with a second inclined block to push the slider seat back to its original position during mold closing. A core puller is fixedly connected to the side of the slider away from the product. The mechanism is used to drive the slider to exit the side structure of the product through the core-pulling mechanism. The core-pulling mechanism includes an inclined guide post and a core-pulling seat. The inclined guide post is fixed in the female mold, and the core-pulling seat is slidably connected in the male mold. The side of the core-pulling seat near the female mold has an inclined hole, which is used to drive the core-pulling seat to move under the action of the inclined guide post. The inclined hole has a clearance hole, which is used to clear the inclined guide post during the first mold opening. The side of the core-pulling seat that contacts the shovel base has a third inclined surface, a second straight surface, and a fourth inclined surface. The third inclined surface cooperates with the second inclined surface, which is used to push the core-pulling seat to reset when the mold is closed. The third and fourth inclined surfaces cooperate with the first and second inclined surfaces, respectively, to tighten the core-pulling seat after the mold is closed. The first straight surface and the second straight surface cooperate to fix the core-pulling seat.

[0008] Preferably, the sliding end of the core-pulling seat is provided with a slide table, which slides inside the pressure plate. The pressure plate is fixed inside the male mold and serves as a guide when the core-pulling seat moves.

[0009] Preferably, the bottom of the core-pulling seat is provided with a first wear-resistant plate, which is used to reduce wear when the core-pulling seat slides with the male mold.

[0010] Preferably, a second wear-resistant plate is provided on the side of the core-pulling seat that contacts the shovel base. The second wear-resistant plate is used to reduce wear when the core-pulling seat slides between the shovel base and the shovel base.

[0011] Preferably, a limiting member is provided in the retraction direction of the core puller, and the limiting member is used to restrict the displacement of the core puller.

[0012] Preferably, the limiting element includes, but is not limited to, a limiting screw.

[0013] The beneficial effects of this invention are as follows: This invention employs a combined slider core-pulling mechanism, in which a slider is slidably mounted within a male mold, a slider insert and a slider seat are slidably mounted within the slider, the slider insert and slider seat are fixedly connected, and a core-pulling seat is fixedly connected to the side of the slider away from the product. The core-pulling seat has an oblique hole and a clearance hole, and a pusher block and an oblique guide post are fixedly connected within a female mold. When the mold opens, the first oblique block of the pusher block pushes the third oblique block of the slider seat, causing the slider insert fixedly connected to it to exit the rib position of the product's side end structure. At this time, the oblique guide post moves within the clearance hole, and the core-pulling seat remains stationary relative to the male mold. Subsequently, under the action of the oblique guide post on the oblique hole, the slider fixedly connected to the core-pulling seat exits the product's side end structure. This achieves the slider insert exiting the rib position of the product's side end structure first, and then the slider exiting the product's side end structure, avoiding the product being stretched and deformed when the slider exits both the product's side end structure and the rib position simultaneously, which would affect the product yield.

Detailed Implementation Methods

[0023] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the embodiments of the present invention and their accompanying drawings.

[0024] This invention provides a combined slider core-pulling mechanism, comprising:

[0025] The mother mold 100 has a mother mold core 110 inside it. A push block 120 is fixedly connected inside the mother mold core 110. The push block 120 has a first inclined block 121 and a second inclined block 122. A shovel base 130 is provided on the side of the push block 120 away from the product 20. The shovel base 130 is fixedly connected inside the mother mold 100. The side of the shovel base 130 that contacts the core-pulling seat 231 has a first inclined surface 131, a first straight surface 133 and a second inclined surface 132.

[0026] A male mold 200 is provided, containing a male mold core 210. A slider 220 is slidably connected within the male mold core 210. The side of the slider 220 that contacts the product 20 is modeled after the side end structure 30 of the product 20, used to mold the side end structure 30 of the product 20. A movable groove 221 is provided within the slider 220, and a slider insert 222 is slidably disposed within the movable groove 221. The side of the slider insert 222 that contacts the product 20 is modeled after the rib 40 of the product 20, used to mold the rib 40 of the product 20. The slider insert 222 is located away from the product 20. One end of product 20 is fixedly connected to slider seat 223, which is slidably disposed in movable groove 221. A third inclined block 224 is provided on the side of slider seat 223 that contacts push block 120. The third inclined block 224 cooperates with the first inclined block 121 to push slider seat 223 away from rib 40 of side end structure 30 of product 20 when mold opening. The third inclined block 224 cooperates with the second inclined block 122 to push slider seat 223 back to its original position when mold closing. The side of slider 220 away from product 20 is fixedly connected to core pulling mechanism 23. 0. A side structure 30 for using a core-pulling mechanism 230 to drive a slider 220 out of product 20. The core-pulling mechanism 230 includes an inclined guide post 140 and a core-pulling seat 231. The inclined guide post 140 is fixed inside the female mold 100, and the core-pulling seat 231 is slidably connected inside the male mold 200. The side of the core-pulling seat 231 near the female mold 100 has an inclined hole 233, which is used to drive the core-pulling seat 231 to move under the action of the inclined guide post 140. An empty hole 234 is provided in the inclined hole 233 to avoid the first mold opening. The hollow inclined guide post 140 has a third inclined surface 235, a second straight surface 238, and a fourth inclined surface 236 on the side of the core-pulling seat 231 that contacts the shovel base 130. The third inclined surface 235 cooperates with the second inclined surface 132 and is used to push the core-pulling seat 231 back to its original position when the mold is closed. The third inclined surface 235 and the fourth inclined surface 236 cooperate with the first inclined surface 131 and the second inclined surface 132 respectively and are used to tighten the core-pulling seat 231 after the mold is closed. The first straight surface 133 and the second straight surface 238 cooperate to fix the core-pulling seat 231.

[0027] The core-pulling seat 231 has a sliding table 232 at its sliding end. The sliding table 232 slides inside the pressure plate 237, which is fixed inside the male mold 200. It serves as a guide when the core-pulling seat 231 moves.

[0028] The core-pulling seat 231 has a first wear-resistant plate 240 at its bottom, which is used to reduce wear when the core-pulling seat 231 slides with the male mold 200.

[0029] Among them, a second wear-resistant plate 250 is provided on the side of the core-pulling seat 231 that contacts the shovel base 130. The second wear-resistant plate 250 is used to reduce wear when the core-pulling seat 231 slides between the shovel base 130.

[0030] The core puller 231 is provided with a limiting member 260 in the exit direction, which is used to limit the displacement of the core puller 231.

[0031] The limiting component 260 includes, but is not limited to, a limiting screw.

[0032] The working process of this invention is as follows:

[0033] When the mold is opened for the first time: the female mold 100 moves relative to the male mold 200. The first inclined block 121 of the inner push block 120 of the female mold 100 pushes the third inclined block 224 of the slider seat 223, causing the slider insert 222 to move in the movable groove 221 of the slider 220 to the rib position 40 of the product 20. At this time, the inclined guide post 140 moves in the clearance hole 234 of the core pulling seat 231, and the core pulling seat 231 is stationary relative to the male mold 200.

[0034] When the mold is fully opened, the female mold 100 continues to move relative to the male mold 200. The inclined guide post 140 inside the female mold 100 pushes the core-pulling seat 231 to move, which causes the slider 220 fixedly connected to it to move to the side end structure 30 of the product 20. At the same time, the slider 220 drives the slider insert 222 and the slider seat 223 to move away from the product 20 together.

[0035] When the mold is closed, the female mold 100 moves relative to the male mold 200. The inclined guide post 140 inside the female mold 100 pushes the core-pulling seat 231 to move, causing it to drive the slider 220 fixedly connected to it to reset. At the same time, it pushes the slider seat 223 and the slider insert 222 to move together. Then, the third inclined block 224 of the slider seat 223, under the action of the second inclined block 122 of the push block 120, drives the slider insert 222 fixedly connected to it to reset.

[0036] The beneficial effect of this invention is that it employs a combined slider core-pulling mechanism, in which a slider 220 is slidably disposed within a male mold 200, a slider insert 222 and a slider seat 223 are slidably disposed within the slider 220, the slider insert 222 and the slider seat 223 are fixedly connected, and a core-pulling seat 231 is fixedly connected to the side of the slider 220 away from the product 20. The core-pulling seat 231 has an inclined hole 233 and a clearance hole 234, and a lever 120 and an inclined guide post 140 are fixedly connected within a female mold 100. When the mold is opened, the first inclined block 121 of the lever 120 moves the third inclined block 224 of the slider seat 223, causing it to drive the slider insert fixedly connected thereto. When the slider 222 exits from the rib 40 of the side structure 30 of the product 20, the inclined guide post 140 moves within the clearance hole 234, and the core-pulling seat 231 remains stationary relative to the male mold 200. Subsequently, under the action of the inclined guide post 140 on the inclined hole 233, the slider 222, which is fixedly connected to the core-pulling seat 231, exits from the side structure 30 of the product 20. This achieves the following: the slider 222 exits from the rib 40 of the side structure 30 of the product 20 first, and then the slider 220 exits from the side structure 30 of the product 20. This avoids the situation where the slider 220 exits from both the side structure 30 and the rib 40 of the product 20 simultaneously, which would cause the product 20 to be stretched and deformed, affecting the yield of the product 20.

[0037] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments based on the technical solutions of the present invention shall fall within the protection scope of the present invention.
