Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, and in particular to a universal moving template for injection molding machines. Background Technology

[0002] Existing injection molding moving templates can be divided into sliding foot moving templates and linear guide moving templates. The structure of the sliding foot moving template is based on Chinese Patent No. CN206277587U, which includes a moving template and a sliding foot device. This type of moving template achieves guided sliding and also requires a guiding structure formed by guide rods and guide holes. Therefore, guide holes need to be provided on the sliding foot moving template. The linear guide moving template is based on Chinese Patent No. CN208993015U, which includes a moving template and a linear guide slider. The linear guide slider can achieve guided sliding after cooperating with the linear guide, without the need for a separate guiding structure. Therefore, guide holes do not need to be provided on the linear guide moving template.

[0003] Under normal conditions, the two types of moving templates have different structures and the installation positions of the sliding foot device and the linear guide slider are different, which makes it impossible for the two types of moving templates to be universal and their adaptability needs to be improved. Utility Model Content

[0004] This invention addresses the shortcoming of existing linear guide injection molding machines and sliding foot injection molding machines having incompatible moving templates by providing a universal moving template for injection molding machines.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A universal moving template for injection molding machines includes a template body and guide holes disposed on the template body. The template body is equipped with a sliding foot device and a linear guide slider. An assembly structure is provided at the bottom of the template body to enable switching between the sliding foot device and the linear guide slider. The assembly structure includes mounting feet fixedly disposed on both sides of the bottom of the template body and mounting structures disposed on the mounting feet for connecting with the sliding foot device or the linear guide slider.

[0007] By adopting the above solution, the mounting structure set on the mounting feet can realize the connection between the mounting feet and the sliding foot device or the linear guide slider, so that this moving template can be installed on the sliding foot machine or the linear guide machine for use, realizing the versatility of the moving template, improving its utilization rate, and reducing production costs.

[0008] Preferably, the mounting structure includes a positioning groove provided at the end of the mounting leg away from the template body for positioning and inserting a sliding foot device or a linear guide slider. At least two assembly holes are provided at the bottom of the positioning groove and the top of the mounting leg, which are aligned with the mounting screw holes on the sliding foot device or the linear guide slider. Fixing bolts that are screwed into the mounting screw holes and engaged with the corresponding assembly holes are screwed into the mounting screw holes.

[0009] Using the above solution, the positioning groove on the mounting foot allows for partial insertion of the sliding foot device or linear guide slider, and positions the inserted sliding foot device or linear guide slider. This facilitates the alignment of the mounting screw holes on the sliding foot device or linear guide slider with the assembly holes on the mounting foot. Once the mounting screw holes and assembly holes are aligned, the fixing bolts can be screwed into the mounting screw holes and assembly holes, thereby achieving the connection between the mounting foot and the sliding foot device or linear guide slider. This allows the moving template to be fixed with the linear guide slider on the linear guide machine and the sliding foot device on the sliding foot machine, thus achieving the universality of the moving template between the linear guide machine and the sliding foot machine, reducing production costs.

[0010] Preferably, the mounting feet are equipped with an adjustment structure to ensure that the template body and the fixed template are parallel.

[0011] Preferably, the adjustment structure includes symmetrically arranged adjustment screw holes on both sides of the top of the mounting leg and adjustment top pressure bolts screwed into the adjustment screw holes and abutting against the linear guide slider, and there is an adjustment gap between the assembly hole on the positioning groove and the fixing bolt inserted therein, which allows the mounting leg to move longitudinally.

[0012] Using the above method, when the template body is fixed to the linear guide slider and the parallelism between it and the fixed template needs to be adjusted, the adjusting top pressure bolt can be screwed into the adjusting screw hole. At this time, the adjusting top pressure bolt will press against the linear guide slider. As the adjusting top pressure bolt continues to be screwed in, the adjusting top pressure bolt will lift the template body by the reaction force generated by pressing against the linear guide slider, thereby realizing the adjustment of its parallelism with the fixed template.

[0013] Preferably, three guide hole seats are symmetrically arranged in a triangular pattern on each side of the template body. Of the three guide hole seats, one is located at the top, and the other two are distributed at intervals at the bottom along the moving direction of the template body, with the guide holes in the two bottom guide hole seats being concentrically arranged.

[0014] Using the above scheme, the guide holes set in the guide hole seats allow the tie rod to be inserted and guide the movement of the tie rod. By setting three guide hole seats and distributing the three guide hole seats in a triangular manner, the tie rod forms a triangular support for the template body, thereby improving the support effect of the tie rod on the template body.

[0015] Preferably, a lubricating sleeve for reducing damping is interference-fitted into the guide hole of each guide hole seat.

[0016] By adopting the above solution, the lubricating sleeve set in the guide hole can reduce the damping when the tie rod slides in the guide hole, making the tie rod move more smoothly in the guide hole. At the same time, it can also reduce the wear generated when the tie rod slides in the guide hole, thereby increasing the service life of the tie rod.

[0017] Preferably, the lubrication sleeve is a copper sleeve.

[0018] Preferably, the copper sleeve has a graphite layer inside to further reduce the damping between the tie rod and the copper sleeve.

[0019] By adopting the above solution, the graphite layer set inside the copper sleeve can further reduce the friction between the tie rod and the inner wall of the copper sleeve, allowing the tie rod to slide more smoothly inside the copper sleeve. At the same time, it can further reduce wear between the two and improve their service life.

[0020] This utility model has significant technical effects due to the adoption of the above technical solutions: the mounting structure set on the mounting feet can realize the connection between the mounting feet and the sliding foot device or the linear guide slider, so that this moving template can be installed on the sliding foot machine or the linear guide machine for use, realizing the versatility of the moving template, improving its utilization rate, and reducing production costs.
