DETAILED DESCRIPTION

[0022] As shown in the accompanying Figures 1-12 , a two-way inclined top row mechanism of a charging pile body injection mold, comprising a front mold plate 1, a rear mold plate 2, a front mold core 3, a rear mold core 4, a charging pile body 5, an inclined guide pillar 6, an inclined guide pillar seat 7, a row seat 8, a row 9, a limit insert one 10, a limit pin 11, a wear block one 12, a wear block two 13, an inclined top pull pin 14, a reset spring one 15, a limit block 16, a wedge-shaped insert 17, an inclined top one 18, a row pressing block 19, an insert pull pin 20, a sliding insert 21, a limit insert two 22, a pressing block 23, an inclined top two 24, and a reset spring two 25, the two-way inclined top row mechanism of the charging pile body injection mold comprises an injection molding product cavity system, a row mechanism, a top inclined top mechanism, and a bottom inclined top mechanism.

[0023] As shown in the accompanying Figure 1 , the charging pile body 5 is an injection molding product, which has a vertical downward direction buckle structure at the top, a horizontal left direction buckle structure on the left side, and a vertical upward direction buckle structure at the bottom. When the injection molding production is completed and demolded, the action sequence of the injection mold row mechanism and the upper and lower two sets of inclined top mechanism needs to be controlled to realize the smooth demolding of the charging pile body 5. The injection mold opening action contains two stages.

[0024] As attached Figures 2-12 The images show the state of the mold mechanism when the injection mold is closed and the injection is complete. After the charging pile body 5 is injection molded, in the first stage of mold opening, the front mold plate 1 moves upward relative to the rear mold plate 2, causing the inclined guide pillar seat 7, inclined guide pillar 6, limit insert 10, wedge insert 17 and front mold core 3 to move upward together. The front mold core 3 moves upward relative to the charging pile body 5 and separates from it. The upward movement of the inclined guide pillar 6 causes the slide seat 8, slide 9, wear-resistant block 12 and limit block 16 to move upward together. Moving horizontally to the left, during this stage, when the limiting insert 10 moves upward, the left end of the limiting pin 11 abuts against the right vertical limiting surface of the limiting insert 10. The charging pile body 5, the limiting pin 11, and the inclined top pull pin 14 remain in position relative to the rear template 2. The inclined top pull pin 14 pushes the inclined top 18 vertically downward along the inclined slide groove on the slide 9 that matches the shape of the inclined top 18. The latching structure at the top of the inclined top 18 disengages from the vertical downward latching at the top of the charging pile body 5. During this stage, the limiting insert 2... 2. The inverted V-shaped protrusion at the bottom is engaged in the V-shaped groove on the wear-resistant block 13. The position of the limiting insert 22 relative to the rear template 2 remains unchanged. The sliding seat 8 and the sliding position 9 slide horizontally to the left relative to the insert pin 20, the sliding insert 21 and the limiting insert 22. The sliding insert 21 pushes the inclined top 24 to move vertically upward along the inclined hole opened on the sliding position 9, which is consistent with its shape. The buckling structure at the end of the inclined top 24 disengages from the vertical upward buckling at the bottom of the charging pile body 5. The front template 1 continues to drive the limiting insert. Insert 10 and inclined guide post 6 move upward, and limit pin 11 slides over the vertical limiting surface on the right side of limit insert 10 and enters its bottom inclined surface. The inclined guide post 6 drives the slide seat 8 to continue moving to the left relative to limit insert 22 until the inverted V-shaped boss at the top of limit insert 22 enters the inverted V-shaped groove at the bottom of slide seat 8. The shoulder of the left end of insert pull pin 20 contacts the left end face of the shoulder of the stepped hole on slide seat 8 that is consistent with its shape. At this time, the first stage of injection mold opening ends.

[0025] The second stage of opening the injection mold, the front mold plate 1 continues to drive the inclined guide pillar 6 to move upward, driving the row seat 8 and the row 9 to move horizontally to the left. At this time, the inverted V-shaped groove at the top of the limiting insert two 22 is clamped into the inverted V-shaped groove at the bottom of the row seat 8. Under the driving of the horizontal left movement of the row seat 8 and the row 9, the limiting needle 11, the wear-resistant block one 12, the inclined top pull needle 14, the reset spring one 15, the limiting block 16, the inclined top one 18, the insert pull needle 20, the sliding insert 21, the limiting insert two 22, the pressing block 23, the inclined top two 24 and the reset spring two 25 move horizontally to the left together. The row mechanism, the top inclined top mechanism and the bottom inclined top mechanism of the injection mold are separated from the left side of the charging pile body 5. The charging pile body 5 is completely separated from the injection mold cavity, and a cycle of injection molding production is completed. The pre-pressed reset spring one 15 pushes the inclined top pull needle 14 to the left relative to the row 9 to the left side of the limiting needle 11, and the inclined top pull needle 14 drives the inclined top one 18 to move upward and left relative to the row 9 along the inclined sliding groove on the row 9. The inclined top one 18 is reset relative to the row 9 to the state when the injection mold is closed.

[0026] The first stage of closing the injection mold, the front mold plate 1 moves downward relative to the rear mold plate 2, driving the front mold core 3, the inclined guide pillar seat 7, the inclined guide pillar 6, the limiting insert one 10 and the wedge-shaped insert 17 to move downward together. The downward movement of the inclined guide pillar 6 drives the row seat 8 and the row 9 to move horizontally to the right along the upper surface of the wear-resistant block two 13, driving the limiting needle 11, the wear-resistant block one 12, the inclined top pull needle 14, the reset spring one 15, the limiting block 16, the inclined top one 18, the insert pull needle 20, the sliding insert 21, the limiting insert two 22, the pressing block 23, the inclined top two 24 and the reset spring two 25 to move horizontally to the right together until the V-shaped boss at the bottom of the limiting insert two 22 slides into the V-shaped groove on the wear-resistant block two 13. At this time, the first stage of closing the injection mold is completed.

[0027] In the second stage of the injection mold clamping, the front mold plate 1 continues to move downward relative to the back mold plate 2, driving the row seat 8 and the row 9 to continue to move horizontally to the right, the V-shaped boss at the bottom of the limiting insert two 22 is clamped in the V-shaped groove provided on the wear-resistant block two 13, the position of the limiting insert two 22 relative to the back mold plate 2 remains unchanged, the row 9 continues to move right relative to the sliding insert 21, the sliding insert 21 pulls the inclined top two 24 to move obliquely downward relative to the row 9 along the oblique sliding groove provided on the row 9, the relative position of the inclined top two 24 and the row 9 is reset to the state when the injection mold is clamped, the pre-pressed reset spring two 25 presses the sliding insert 21 to the left during the clamping of the injection mold, ensuring the accurate reset position of the inclined top two 24, the V-shaped boss at the bottom of the wedge-shaped insert 17 cooperates with the pressed inclined top one 18 to ensure the accurate reset position of the inclined top one 18, at this time, the lower surface of the front mold core 3 contacts the lower surface of the back mold core 4, the front mold core 3, the back mold core 4, the inclined top one 18, the inclined top two 24 and the row 9 form an injection molding cavity of the charging pile main body 5, preparing for the next injection molding cycle.

[0028] The bidirectional inclined top row mechanism of the charging pile main body injection mold realizes smooth demolding of the charging pile main body product in three directions through the cooperation and movement sequence control of the injection mold row mechanism and the upper and lower two sets of inclined top mechanisms, the inclined top mechanism is nested in the row mechanism to effectively reduce the overall size of the injection mold, and the processing and manufacturing cost and period of the injection mold are reduced.

[0029] The above is the preferred embodiment of the present application, which aims to explain the content and idea of the present application, and the content of the specification should not be understood as a limitation of the present application.
