[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] Example 1:

[0033] In this embodiment, as Figures 1-11 As shown, the present invention proposes an inverted demolding mechanism, comprising a rear mold core main insert 1, a product 2 on the top of the rear mold core main insert, a side hole 201 in the middle of the product, a rear mold core insert 1 (3) and a rear mold core insert 2 (4) on the bottom of the rear mold core main insert, the tops of the rear mold core insert 1 and the rear mold core insert 2 (4) passing through the rear mold core main insert and abutting against the bottom of the product, a rocker arm 5 between the rear mold core insert 1 and the rear mold core insert 2 (4), a protrusion 501 on one side of the top of the rocker arm, the protrusion being inserted into the side hole corresponding to the protrusion, and a rocker arm 5 on the other side of the top of the rocker arm. There is a first inclined surface 502, a second inclined surface 503 in the middle of the rocker arm, a rocker arm support 6 at the bottom of the rocker arm, a third inclined surface 301 at the top of the first rear mold core insert, the third inclined surface abutting against the first inclined surface, and a fourth inclined surface 401 in the middle of the second rear mold core insert, the fourth inclined surface abutting against the second inclined surface. The rocker arm support is driven by the drive assembly to move towards the main insert of the rear mold core, thereby driving the rocker arm and the product to move forward. The second inclined surface of the rocker arm moves to the fourth inclined surface of the second rear mold core insert for lateral displacement, thereby completing the demolding of the protrusion and the side hole.

[0034] In the present example, the driving assembly is a prior art, which can be driven by a driving motor or a cylinder. The driving assembly is not shown in the figure.

[0035] In the present example, the rear die core main insert is further provided with a through groove 101 in the middle part, which is used for the rear die core insert one, the swing rod and the rear die core insert to pass through.

[0036] In the present example, the rear die core insert one and the rear die core insert two are further provided with a swing rod cavity 7, which is used for accommodating the swing rod to pass through.

[0037] In the present example, the width of the middle section of the swing rod is smaller than the width of the lower section of the swing rod, and the width of the middle section of the swing rod cavity needs to be greater than the width of the lower section of the swing rod, so as to avoid the swing rod from being unable to move in the swing rod cavity.

[0038] In the present example, the initial state of the swing rod in the swing rod cavity is that the convex column is inserted into the side hole in correspondence, the inclined surface one is in abutment with the inclined surface three in correspondence, and the top surface of the swing rod is in abutment with the bottom surface of the product. When the swing rod moves forward, the convex column is inserted into the side hole in correspondence, and the inclined surface one is separated from the inclined surface three. When the swing rod continues to move forward, until the inclined surface two moves to the inclined surface four and is in abutment with the inclined surface four, the inclined surface two is laterally extruded by the inclined surface four, the swing rod is laterally displaced, until the inclined surface one is in abutment with the inclined surface three again, at this time the convex column is separated from the side hole to complete the demolding of the side hole. The swing rod continues to move forward to eject the product. The above movement process of the swing rod is completed in the swing rod cavity, and the rear die core main insert, the rear die core insert one and the rear die core insert two do not produce any movement in the process. The inclined surface three and the inclined surface four play a guiding role, and at the same time the inclined surface three can limit the swing rod when the swing rod is retracted.

[0039] In the present example, the bottom of the swing rod is provided with a clamping groove 504, and the top of the swing rod holder is provided with a track groove 601. The clamping groove and the track groove are inserted in correspondence.

[0040] In the present example, since the swing rod produces lateral displacement, it is necessary to provide a track groove for the swing rod to move left and right. The clamping groove and the track groove are inserted in correspondence in the transverse direction, so that the swing rod cannot be separated from the swing rod holder in the vertical direction, thereby improving the stability of the swing rod.

[0041] In the present example, the top of the rear die core insert two is provided with a cylinder 402, and the top of the product is provided with a circular hole 202. The cylinder and the circular hole are inserted in correspondence.

[0042] In the present example, the bottom of the rear die core main insert is provided with a rear die core insert three 8, a rear die core insert four 9 and a rear die core insert five 10. The top of the rear die core insert three is provided with a square column one 801, the top of the rear die core insert four is provided with a square column two 901, and the top of the rear die core insert five is provided with a square column three, which is not shown in the figure.

[0043] Further provided in the embodiment is that the product is provided with square hole one 203 and square hole two 204 at the top, and is provided with square groove 205 at the bottom, square column one is inserted into square hole one, square column two is inserted into square hole two, and square column three is inserted into square groove.

[0044] In the embodiment, since the rear die core main insert cannot meet the requirements of all hole positions of the product, the rear die core insert one, the swing rod and the rear die core insert two are provided to meet the requirements of part of the hole positions of the product and to demold the side hole of the product, and the rear die core insert three, the rear die core insert four and the rear die core insert five are provided to meet the requirements of another part of the hole positions of the product.

[0045] The working principle of the demolding mechanism of the reverse buckle is that after the product is formed, the output end of the driving assembly is connected with the swing rod holder, the output end of the driving assembly is elongated, the swing rod holder is moved to the direction of the rear die core main insert, thereby driving the swing rod and the product to move forward, at this time, the convex column is still inserted into the side hole, the bottom of the product is separated from the rear die core main insert, and the product only remains the four-edge shell which is still sleeved on the rear die core main insert, when the inclined surface two of the swing rod moves to the inclined surface four of the rear die core insert two, the inclined surface two is laterally extruded by the inclined surface four, the swing rod is laterally displaced, at this time, the convex column is separated from the side hole to complete the demolding of the side hole, and the swing rod continues to move forward to eject the product.
