TECHNICAL FIELD

[0001] The present application relates to the field of splicing molds, in particular to a high-precision split structure of a flow divider. BACKGROUND

[0002] The flow divider is a component of an injection mold, and the mold has a large volume. If a steel blank is used for processing, the overall processing difficulty is large, and it is not conducive to disassembly, replacement and maintenance in the later stage.

[0003] Splicing molds are also used in some sub-mold fields, but the splicing forms are different. If the splicing scheme is not well designed, it will cause path space interference during splicing, and there will be difficulty in splicing. Or after splicing, the stability of the overall mold is not enough. SUMMARY

[0004] The problem to be solved by the present application is to provide a high-precision split structure of a flow divider, which divides the flow divider mold into three parts that can be split, facilitating replacement and maintenance, and the stability after splitting is also better.

[0005] To solve the above problems, the present application provides a high-precision split structure of a flow divider, and to achieve the above purpose, the technical scheme adopted by the present application to solve its technical problems is:

[0006] A high-precision split structure of a flow divider, comprising: a rear block, the intersection of the top surface and the side surface of the rear block is provided with a first recess; a front block, the intersection of the top surface and the side surface of the front block is provided with a second recess, the first recess and the second recess are split to form a rectangular recess; a flow divider, comprising an upper circular truncated cone, the root of the upper circular truncated cone is integrally connected with a rounded rectangular plate, the rounded rectangular plate is assembled with the rectangular recess; the inner wall side surface of the first recess is provided with a side recess, and the rounded rectangular plate is provided with a side protrusion assembled with the side recess; the rear block and the front block are respectively provided with a protrusion and a notch which are mutually abutted, the number of the protrusions is three, and the three protrusions sequentially connected form a triangle.

[0007] The beneficial effects of the above technical scheme are: the present technical scheme is mainly divided into three parts that can be split, namely the rear block, the front block and the flow divider. First, it is convenient to disassemble, replace and maintain, that is, the damaged flow divider can be replaced, and different specifications of flow dividers can be installed as needed, which has a wide range of applications. Second, the rounded rectangular plate serves as a base with a large horizontal area, which plays a role of a stable base after being matched with the rectangular recess. Third, the front block and the rear block are independent of each other, so the rectangular recess can be disassembled, and the replacement and installation of the flow divider are facilitated. Fourth, the front block and the rear block have multiple protrusions and notches, which are assembled and engaged with each other, and the assembly is relatively firm.

[0008] As a further improvement of the present application, the protrusions include two side protrusions and one lower protrusion, the two side protrusions are at the same height, and the lower protrusion is lower than the height of the side protrusions; the gaps include side gaps matched with the side protrusions, and a bottom gap matched with the lower protrusion.

[0009] The beneficial effect of the above technical solution is that the layout of the multiple protrusions makes the occlusion force very firm.

[0010] As a further improvement of the present application, the side protrusions are exposed to the side vertical surface of the rear block on the side away from each other, and the lower surface of the lower protrusion is exposed to the lower surface of the rear block; the side gaps are exposed to the side vertical surface of the front block on the side away from each other, and the lower opening of the bottom gap is exposed to the lower surface of the front block.

[0011] The beneficial effect of the above technical solution is that the layout of the side protrusions, the lower protrusion, the side gaps, and the bottom gap also takes into account the ease of processing.

[0012] As a further improvement of the present application, the side away from each other of the side protrusions has a fillet, and the top of the lower protrusion also has a fillet.

[0013] The beneficial effect of the above technical solution is that the fillet reduces the resistance force when the protrusions and the gaps are matched with each other.

[0014] As a further improvement of the present application, the space occupied by the first recess is larger than the space occupied by the second recess; one end of the side groove is in communication with the contact surface of the front block and the rear block.

[0015] The beneficial effect of the above technical solution is that the first recess has a relatively large volume, so it is suitable for arranging the side groove, and the round rectangular plate can be arranged in the first recess in a side sliding manner.

[0016] As a further improvement of the present application, the end of the front block away from the rear block has a concave-convex surface.

[0017] The beneficial effect of the above technical solution is that the concave-convex surface is an operation surface of the front block as a mold.

[0018] As a further improvement of the present application, the end of the rear block away from the front block is fixed with a horizontal ejector rod, and the ejector rod drives the front block, the rear block, and the flow divider to move synchronously horizontally.

[0019] The beneficial effect of the above technical solution is that the ejector rod makes the mold assembly have a mechanical degree of freedom.

[0020] As a further improvement of the present application, the rear block protrudes with horizontal ribs on both sides, and side limit blocks are arranged on both sides of the rear block and movably assembled with the horizontal ribs.

[0021] The beneficial effect of adopting the above technical solution is that the horizontal ribs are equivalent to guide rails, providing a linear guiding function for their own translation.

[0022] As a further improvement of the present invention, a bottom plate is provided below the rear block, and the bottom plate has a straight groove for movable assembly with the rear block.

[0023] The beneficial effects of adopting the above technical solution are: the design of the base plate also plays the role of linear guidance and limiting, but the base plate and the side limiting block provide semi-enclosed limiting for the rear block, resulting in better limiting stability.
