[0039] See also Figure 1-Figure 17 The utility model discloses a two-stage mold opening mold for injection molding a product 100.
[0040] See also Figure 1-Figure 5 The two-stage open mold comprises an upper mold base 1, a lower mold base 2, a sliding seat 10 and a sliding seat 50 that can move horizontally along the lower mold base 2, a push-pull plate 40 fixed to the sliding seat 10 for driving the sliding seat 50 to move, and an inclined guide column 20 installed on the upper mold base 1 for driving the sliding seat 10 to move. The upper surface of the sliding seat 50 is recessed with a sliding space, and at least part of the push-pull plate 40 is slidably arranged in the sliding space. Furthermore, sliding grooves 51 connected to the sliding space are provided on opposite sides of the upper surface of the sliding seat 50, and the push-pull plate 40 is convexly provided with a sliding block 42 movable in the sliding groove 51. The lower mold base 2 is provided with a locking column 70 for locking the sliding seat 50, and the sliding seat 10 is provided with an unlocking block 60 for cooperating with the locking column 70 to unlock the sliding seat 50.
[0041] In this embodiment, the two-stage mold opening mold includes a first stage mold opening and a second stage mold opening.
[0042] When the two-stage mold opening mold performs the first stage of mold opening, the inclined guide column 20 drives the slide seat 10 to move horizontally to the left, the locking column 70 locks the sliding seat 50, and the sliding block 42 of the push-pull plate 40 slides to the left along the sliding groove 51 and abuts against a side wall of the sliding groove 51;
[0043] When the two-stage mold is opened for the second time, the unlocking block 60 drives the locking column 70 to unlock the sliding seat 50 , and the sliding block 42 of the push-pull plate 40 drives the sliding seat 50 to continue to move horizontally to the left following the sliding seat 10 .
[0044] See also Figure 2 , Fig.10 and Fig.12 A locking groove 53 is recessed at the bottom of the sliding seat 50 . When the locking column 70 locks the sliding seat 50 , the top end of the locking column 70 is stuck in the locking groove 53 .
[0045] See also Figure 4 and Figure 5 In more detail, a rest surface 61 is provided on the lower surface of the free end of the unlocking block 60, and the locking column 70 is provided with a contact surface 71 matching the rest surface 61. When the two-stage mold opening mold performs the second stage of mold opening, the rest surface 61 of the unlocking block 60 abuts against the rest surface 71 of the locking column 70 and pushes the locking column 70 downward to make the top end of the locking column 70 disengage from the locking groove 53, so that the push-pull plate 40 installed on the sliding seat 10 drives the sliding seat 50 to move to the left.
[0046] See also Figure 4 , Figure 6 and Fig.12 The bottom end of the locking column 70 is recessed with a mounting groove 73 for accommodating a spring 80. The locking column 70 is movably arranged on the lower die base 2 along the vertical direction, and the two ends of the spring 80 respectively abut against the lower die base 2 and the bottom wall of the mounting groove 73.
[0047] Furthermore, a limiting protrusion 72 for limiting the locking column 70 from being separated from the lower die base 2 is convexly provided on a side wall of the bottom end of the locking column 70 .
[0048] See also Figure 6 , Figure 7 and Fig.11 A fixing groove 12 is recessed on one end of the upper surface of the sliding seat 10 away from the sliding seat 50, and a fixing block 41 is protruded on the push-pull plate 40. The fixing block 41 is correspondingly installed in the fixing groove 12. Through the cooperation between the fixing block 41 and the fixing groove 12, the sliding seat 10 can drive the push-pull plate 40 to move.
[0049] See also Figure 7-Figure 9 , Fig.16 and Fig.17 The upper surface of the push-pull plate 40 is concavely provided with a left half groove 43, and the upper surface of the sliding seat 50 is concavely provided with a right half groove 54. When the two-stage mold is closed, the left half groove 43 is connected with the right half groove 54 to form a flow channel groove for accommodating the nozzle material 200. Furthermore, the side wall of the sliding seat 50 is provided with a glue injection port 55 connected with the right half groove 54. The glue in the flow channel groove is injected into the cavity of the two-stage mold through the glue injection port 55 to manufacture the product 100.
[0050] See also Figure 1 , Figure 6 and Fig.11 The slide seat 10 is provided with an inclined guide hole 11 for sliding with the inclined guide pillar 20. The inclined guide pillar 20 moves up and down driven by the upper mold seat 1, and at the same time, the inclined guide pillar 20 drives the slide seat 10 to move left and right.
[0051] See also Figure 4 and Figure 6 The two-stage opening mold also includes a slider block 30 installed on the upper mold base 1 for cooperating with the movement of the slider seat 10. The slider block 30 is provided with a pushing surface, and the slider seat 10 is provided with a force surface cooperating with the pushing surface. When the two-stage opening mold is closed, the upper mold base 1 drives the slider block 30 to move downward, and at the same time, the pushing surface squeezes the force surface and drives the slider seat 10 to move to the right.
[0052] When the two-stage opening mold of the utility model is used,
[0053] See also Figure 4 and Fig.13When the two-stage open mold is in the mold closing state, the slider seat 10 is fitted with the sliding seat 50, the sliding block 42 of the push-pull plate 40 is accommodated in the sliding groove 51 of the sliding seat 50, the top end of the locking column 70 is clamped in the locking groove 53 on the lower surface of the sliding seat 50, and the abutting surface 61 of the unlocking block 60 and the abutting surface 71 of the locking column 70 are arranged without force on each other. At this time, glue is injected into the flow channel groove and injected into the cavity through the glue injection port 55 to realize cooling and forming of the product 100 in the cavity and the sprue material 200 in the left half groove 43 and the right half groove 54 connected to the product 100. The connecting end 201 of the sprue material 200 is connected to the product 100, and the connecting end 201 is gradually reduced from the right half groove 54 to the cavity direction, so as to facilitate the separation of the sprue material 200 from the product 100.
[0054] See also Fig.14 When the two-stage mold opening mold is transformed from the mold closing state to the first-stage mold opening state, the sliding seat 10 drives the push-pull plate 40 to move to the left, separating the connecting end 201 of the sprue material 200 from the product 100. When the sliding block 42 of the push-pull plate 40 abuts against the side wall of the sliding groove 51 of the sliding seat 50, at the same time, the abutting surface 61 of the unlocking block 60 squeezes the abutting surface 71 of the locking column 70 to make the top end of the locking column 70 disengage from the locking groove 53 of the sliding seat 50. At this time, the product 100 is still attached to the side wall of the sliding seat 50.
[0055] See also Fig.15 When the two-stage mold opening is changed from the first stage mold opening to the second stage mold opening state, the sliding seat 10 drives the push-pull plate 40 to continue to move to the left, and at the same time, the sliding block 42 of the push-pull plate 40 drives the sliding seat 50 to move to the left, so that the product 100 leaves the side wall of the sliding seat 50, and finally takes out the molded product 100, and takes out the sprue material 200 to prepare for the next injection molding process.
[0056] The two-stage mold opening mold provided by the utility model not only has a simple structure, but also separates the nozzle material 200 from the product 100 through the first stage of mold opening, and separates the product 100 from the mold through the second stage of mold opening, thereby improving the process flow and greatly enhancing production efficiency.
[0057] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
