Description

Technical Field

[0001] This utility model belongs to the technical field of injection molding tool holders, and relates to an injection molding tool holder and its reinforcing structure. Background Technology

[0002] Existing injection molding tool holders suffer from systemic technical shortcomings in tool stabilization, primarily manifested in insufficient adaptability to dynamic mechanical response and multi-condition operation. The primary drawback is weakened high-frequency vibration suppression. Since the contact interface between the slide block and the guide rail relies on bolt preload to maintain a rigid connection, assembly gaps and preload attenuation due to long-term load impacts can lead to nonlinear degradation of contact stiffness. Under the cyclic loads of injection molding, this easily causes radial micro-vibration of the tool, directly affecting the dimensional and positional tolerances of the machined surface. Traditional solutions rely on low-thermal-expansion alloys or additional heat dissipation structures. However, the former significantly increases material costs and cannot meet the requirements for rapid tool changeovers, while the latter limits tool placement density due to heat dissipation fins encroaching on assembly space. Therefore, there is an urgent need for an injection molding tool holder and its reinforcing structure to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an injection molding tool holder and reinforcing structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: an injection molding tool fixing bracket and reinforcing structure, including: a rear shell frame and reinforcing support members, wherein a set of reinforcing support members for providing fixed support for several sets of tool bodies is provided at the middle position of the front side of the rear shell frame;

[0005] The reinforcing support includes side fixing seats and positioning holes. There are two sets of side fixing seats, and the side fixing seats are rectangular block structures with embedded grooves. The front side of the two sets of side fixing seats is provided with an inner reinforcing support frame for providing support strength to several sets of tool bodies. The inner reinforcing support frame is connected and fixed to the inner side of the two sets of side fixing seats by bolts. The upper and lower ends of the left and right sides of the inner reinforcing support frame are respectively provided with a set of positioning holes for positioning the tool body. Each set of positioning holes corresponds to a set of tool bodies for positioning and fixing.

[0006] In a preferred embodiment, the upper end of the tool body is provided with a set of positioning tool cylinders for positioning and installation, the lower outer side of the positioning tool cylinders is provided with a set of positioning seats for limiting its position, and the lower end of the positioning seats is provided with a set of connecting support plates for supporting and installing it.

[0007] In a preferred embodiment, the connecting support plate is fixed to the two sets of positioning seats by bolts. Each set of positioning seats has a set of connecting seats on its inner side for adjusting and supporting the vertical position of the connecting support plate. Both sets of connecting seats are fixed to the connecting support plate by bolts.

[0008] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In actual use, the reinforcing support is first positioned to the front side of the rear shell frame through the recessed groove of the side fixing seat. The bolts are tightened to form a rigid support structure with the inner reinforcing support frame and the side fixing seat. Then, the tool body is inserted into the positioning hole of the inner reinforcing support frame. The positioning tool cylinder and the positioning seat complete the axial limitation to ensure that the tool tip is perpendicular to the machining reference surface. During the adjustment stage, the starting electric cylinder drives the connecting support plate to move vertically along the slide rail. The slide and the slide rail cooperate to guide and drive the positioning seat and the tool body to rise and fall synchronously to the preset height. The distance between the two sets of positioning seats is finely adjusted by the connecting seat. The bolts are tightened to lock the relative position of the connecting support plate and the positioning seat, forming a multi-level support system, thereby improving the tool fixing effect and the fixing reinforcement effect.

[0009] In a preferred embodiment, each set of connecting seats is provided with a set of slides on the rear side for guiding the vertical movement of the connecting support plate, and a set of slide rails on the rear side of the slides for guiding the slides to move. The slide rails are fixed to the front end of the rear shell frame by bolts.

[0010] In a preferred embodiment, the slide block is integrally movable with the connecting support plate via a connecting seat. The upper part of the middle position of the connecting support plate is provided with a set of electric cylinders for adjusting its height. The lower end of the electric cylinders is fixed to the rear shell frame by bolts via a mounting plate.

[0011] In a preferred embodiment, the electric cylinder is connected to the connecting support plate in a telescopic direction. The telescopic stroke length of the electric cylinder is less than the front cross-sectional length of the slide rail. There are two sets of connecting support plates, and the two sets of connecting support plates are symmetrically arranged with the middle position of the reinforcing support as the horizontal axis. Each set of connecting support plates is connected to two sets of positioning tool cylinders. After clamping, the radial clearance of the tool body in the positioning hole is re-measured to ensure that the inner reinforcing support and the side fixing seat jointly bear the cutting load. At the same time, the reinforcing support suppresses tool vibration through the distributed support of the inner reinforcing support. The vertical guiding system formed by the slide rail and the slide seat maintains the stability effect when the tool is fixed. When disassembling, the bolt connection is released by reverse operation. The electric cylinder retracts to reset the connecting support plate. The whole process integrates rigid positioning and dynamic adjustment functions to achieve high-precision tool clamping and facilitate quick handling by the operator.
