Description

[Technical Field]

[0001] This invention relates to the field of mold mechanism technology, and in particular to a circular undercut release mechanism. [Background Technology]

[0002] like Figure 1 The product 20 shown here needs to be split into a first structure 30 and a second structure 40 due to structural limitations. This will result in a joint line 50 in the middle of the product 20 after assembly, which will affect the appearance and feel of the product 20.

[0003] In view of this, it is necessary to provide a circular inverted release mechanism to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is that, due to structural limitations, products need to be disassembled into a first structure and a second structure, which are molded separately. This results in a seam after assembly, affecting the product's appearance and feel. Therefore, this invention provides a circular inverted latching mechanism to address this problem.

[0005] The solution to the technical problem of this invention is: a circular inverted latching release mechanism, comprising:

[0006] The connecting plate is provided with a first connecting plate and a second connecting plate. One end of the first connecting plate is fixedly connected to the third movable rod of the third driving member, and it can move under the action of the third driving member. The other end of the first connecting plate is provided with a first slide rail, which can limit the displacement of the third slider. The second connecting plate is fixed in the mold, and one end of the second connecting plate is provided with a second slide rail, which can limit the displacement of the fourth slider.

[0007] The driving component includes a first driving component, a second driving component, and a third driving component. The first driving component and the second driving component can be fixed to a first connecting plate and a second connecting plate, respectively. The first driving component and the second driving component are respectively provided with a first movable rod and a second movable rod. The first movable rod can be fixedly connected to a first transmission component, so that the first transmission component moves under the action of the first driving component. The second movable rod can be fixedly connected to a second transmission component, so that the second transmission component moves under the action of the second driving component. The third driving component is provided with a third movable rod, one end of which is fixedly connected to the first connecting plate, so that the first connecting plate moves under the action of the third driving component.

[0008] The transmission component includes a first transmission component, a second transmission component, a third transmission component, and a fourth transmission component. One end of the first and second transmission components is fixed to the first movable rod of the first drive component and the second movable rod of the second drive component, respectively. The third and fourth transmission components are movably mounted on the first and second connecting plates via a rotating shaft, respectively. One side of the first and second transmission components can cooperate with the third and fourth transmission components to act on one end of the third and fourth sliders, respectively, so that the third and fourth sliders can move along the first and second slide rails to exit the product.

[0009] The slider includes a first slider, a second slider, a third slider, and a fourth slider. One end of the first and second sliders is shaped to one end of the product, and they can exit one side of the product when the mold is opened by the slider body. The third and fourth sliders are respectively movably disposed in the first and second slide rails. One side of the third and fourth sliders is shaped to the other end of the product, and one end of them can move in the first and second slide rails respectively under the action of the transmission component.

[0010] Preferably, the first and second slide rails can be designed as annular shapes according to the shapes of the third and fourth sliders.

[0011] Preferably, the first driving member, the second driving member, and the third driving member can be hydraulic cylinders.

[0012] Preferably, the first transmission component and the second transmission component can be racks.

[0013] Preferably, the third and fourth transmission components can be gears.

[0014] Preferably, one end of the third and fourth sliders can be gear-shaped, which can move under the action of the transmission component.

[0015] The beneficial effects of this invention are that, through a circular inverted ejection mechanism, the product is ejected by the movement of the first and second sliders driven by the slider insert during mold opening, and by the transmission component transmitting power to rotate the third and fourth sliders to eject the product. This allows for ejection with a circular inner shape, thus avoiding the need to disassemble the product into two parts for molding and then assembling, which would result in seam lines. This mechanism can improve the aesthetic appearance of the product and its feel when used. [Attached Image Description]

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 circular inverted latching release mechanism, comprising:

[0025] A connecting plate 110 is provided with a first connecting plate 111 and a second connecting plate 113. One end of the first connecting plate 111 is fixedly connected to the third movable rod 126 of the third driving member 125, and it can move under the action of the third driving member 125. The other end of the first connecting plate 111 is provided with a first slide rail 112, which can limit the displacement of the third slider 143. The second connecting plate 113 is fixed in the mold, and one end of the second connecting plate 113 is provided with a second slide rail 114, which can limit the displacement of the fourth slider 144.

[0026] A driving component 120 is provided, comprising a first driving component 121, a second driving component 123, and a third driving component 125. The first driving component 121 and the second driving component 123 can be fixed to a first connecting plate 111 and a second connecting plate 113, respectively. The first driving component 121 and the second driving component 123 are respectively provided with a first movable rod 122 and a second movable rod 124. The first movable rod 122 can be fixedly connected to a first transmission component 131, causing the first transmission component 131 to move under the action of the first driving component 121. The second movable rod 124 can be fixedly connected to a second transmission component 132, causing the second transmission component 132 to move under the action of the second driving component 123. The third driving component 125 is provided with a third movable rod 126, one end of which is fixedly connected to the first connecting plate 111, allowing the first connecting plate 111 to move under the action of the third driving component 125.

[0027] The transmission component 130 includes a first transmission component 131, a second transmission component 132, a third transmission component 133, and a fourth transmission component 134. One end of the first transmission component 131 and the second transmission component 132 are respectively fixed to the first movable rod 122 of the first driving component 121 and the second movable rod 124 of the second driving component 123. The third transmission component 133 and the fourth transmission component 134 are movably mounted on the first connecting plate 111 and the second connecting plate 113 via a rotating shaft 135. One side of the first transmission component 131 and the second transmission component 132 can cooperate with the third transmission component 133 and the fourth transmission component 134 to act on one end of the third slider 143 and the fourth slider 144, respectively, so that the third slider 143 and the fourth slider 144 can move along the first slide rail 112 and the second slide rail 114 to exit the product 100.

[0028] The slider 140 includes a first slider 141, a second slider 142, a third slider 143, and a fourth slider 144. One end of the first slider 141 and the second slider 142 is shaped to one end of the product 100. They can exit one side of the product 100 when the mold is opened by the slider body (not shown in the figure). The third slider 143 and the fourth slider 144 are respectively movably disposed in the first slide rail 112 and the second slide rail 114. One side of the third slider 143 and the fourth slider 144 is shaped to the other end of the product 100. One end of the third slider 143 and the fourth slider 144 can move in the first slide rail 112 and the second slide rail 114 respectively under the action of the transmission member 130.

[0029] The first slide rail 112 and the second slide rail 114 can be designed as rings according to the shapes of the third slider 143 and the fourth slider 144.

[0030] The first driving component 121, the second driving component 123, and the third driving component 125 can be hydraulic cylinders.

[0031] The first transmission component 131 and the second transmission component 132 may be racks.

[0032] The third transmission component 133 and the fourth transmission component 134 may be gears.

[0033] One end of the third slider 143 and the fourth slider 144 may be gear-shaped, and they may move under the action of the transmission member 130.

[0034] The working process of this invention is as follows: Figure 2 As shown, after product 100 is formed in the mold, the mold is first opened, as follows: Figure 3 As shown, at this time, the first slider 141 and the second slider 142 exit one end of the product 100 due to the action of the slider body (not shown in the figure) when the mold opens, and then... Figure 4 As shown, the first driving member 121 acts on the first transmission member 131 through the first movable rod 122. In this embodiment, the first driving member 121 can push the first transmission member 131 to move 110mm through the first movable rod 122, so that the first transmission member 131 transmits power to the third slider 143 in cooperation with the third transmission member 133, so that the third slider 143 rotates 92° along the first slide rail 112 and exits the product 100. Figure 5 As shown, under the action of the third driving member 125, in this embodiment, the third driving member 125 pulls the first connecting plate 111 30mm away via the third movable rod 126, causing the first connecting plate 111 to drive the third slider 143 moving within the first slide rail 112, which is used to avoid the fourth slider 144 from exiting. Finally, as shown... Figure 6 As shown, under the action of the second driving member 123, in this embodiment, the second driving member 123 pushes the second transmission member 132 to move 110mm through the second movable rod 124, so that the fourth transmission member 134 transmits power to the fourth slider 144 in cooperation with the second transmission member 132, so that the fourth slider 144 rotates 92° along the second slide rail 114 and exits the product 100, thus completing the exit of the first slider 141, the second slider 142, the third slider 143 and the fourth slider 144 from the forming part of the product 100.

[0035] The beneficial effects of this invention are that, through a circular inverted ejection mechanism, the product 100 is ejected by the first slider 141 and the second slider 142 driven by the slider insert (not shown in the figure) when the mold is opened, and by the transmission component 130 transmitting power to make the third slider 143 and the fourth slider 144 rotate to eject the product 100. This can achieve ejection with the inner side of the product 100 in a circular shape, thereby avoiding the need to disassemble the product 100 into two products for molding and then assembling them, which would cause the product 100 to have a joint line 50. This mechanism can improve the appearance and feel of the product 100.
