[0001] The invention relates to the molding of high-end sanitary porcelain toilet product blanks and the realization of the limiting locking of a model, in particular to a rear model locking and tightening device of a five-opening toilet blank high-pressure molding machine. Background Art

[0002] At present, toilet blank high-pressure forming machines are mostly four-model combination forming structures. The positional relationship between the model groups needs to be highly accurately aligned to ensure the effect and efficiency of blank forming. Otherwise, the blank will be partially offset, reducing the blank forming rate and forming effect.

[0003] In the actual production process, compared with conventional products, some high-end toilets have more complex structures and different appearances, requiring a combination of multiple models to meet the requirements of blank molding. Therefore, five-model molding equipment has emerged, that is, a rear model is added on the basis of the existing upper model machine, left and right models, and bottom model. The main position relationship of the rear model is horizontal alignment and tightening with the two side models. Since the five-model molding equipment is not perfect, the limit tightening mechanism of the rear model cannot meet the requirements of high-precision blank molding, and it is impossible to achieve a high-precision blank continuous molding process.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Participate in the Figure 1-4 The rear model locking and tightening device disclosed in the present invention is an innovation of the position limiting and tightening structure between the rear model and the side model.

[0029] In the description of the present invention, it is necessary to understand that the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "upper", "one side", "top", "inside", "front", "center", "both ends" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] The rear mold locking and tightening device of the five-opening toilet blank high-pressure forming machine comprises a tightening mechanism and a locking mechanism. The tightening mechanism is arranged on the rear side of the rear mold mounting base plate, and the locking mechanism is arranged on the side of the rear mold mounting base plate.

[0031] See attached Figure 2The tightening mechanism includes a tightening beam 12, a tightening cylinder 13 and an adjustment assembly. The tightening beam includes a tightening beam body and a tightening beam fork body fixed together. The tightening beam fork body is located at the two ends of the front side of the tightening beam body and is arranged perpendicular to the inner side of the tightening beam body; the tightening beam body is arranged on the rear side of the rear model mounting substrate; the tightening beam fork body is placed on both sides of the rear model mounting substrate. The tightening cylinder 13 is installed inside the tightening beam 12, and its output end contacts the side of the rear model mounting substrate. The adjustment assembly includes a tightening beam slide 6 and a return spring 5; the tightening beam body is hoisted on the tightening beam slide through the sliding ear 17, and the return spring 5 is mounted on the tightening beam slide.

[0032] In this embodiment, see Figure 4 The top beam slide 6 includes a mounting plate 6-2 and an optical axis 6-1; the mounting plate 6-2 is mounted on the rear side of the rear model mounting base plate through a connecting assembly, and the optical axis is vertically arranged with the mounting plate. Figure 3-4 The connection assembly includes an adjusting bolt 7 and an adjusting screw hole. The adjusting screw holes are arranged at the four corners of the mounting plate and are vertically arranged long holes. The adjusting bolt 7 is fixed to the top of the mounting plate to adjust the up and down position of the mounting plate. The upper end of the adjusting bolt 7 is arranged on a fixed plate. The fixed plate is vertically fixed to the side of the rear model mounting base plate. The lower end of the adjusting bolt is fixed to the top of the mounting plate. After loosening the high-strength bolt in the adjusting screw hole, the upper and lower positions of the mounting plate are adjusted by adjusting the adjusting bolt. After it is in place, tighten the high-strength bolt. The height position adjustment of the mounting plate realizes the change of the height position of the entire top tightening beam to match the height position of side models of different specifications.

[0033] In addition to the top tightening beam slide 6 and the return spring 5, the adjustment component also includes a limit sleeve 2 and a spring adjustment sleeve 4, which are sleeved side by side on the optical axis 6-1. The outer side of the limit sleeve contacts the inner side of the outer end sliding ear 17, and the inner side of the spring adjustment sleeve contacts the return spring. The limit sleeve is connected to the optical axis through rivets or high-strength bolts to achieve limited fixation. The limit sleeve 2, the spring adjustment sleeve 4 and the return spring 5 are sleeved on the optical axis of the top tightening beam slide 6 and are located between the two sliding ears on the top tightening beam 12. Each spring adjustment sleeve 4 is provided with two sets of spring pressure adjustment screw assemblies 3 for adjusting the pressure of the return spring 5. The spring adjustment sleeve is also equipped with an adjustment screw assembly, which adjusts the distance between the spring adjustment sleeve and the limit sleeve. Through the adjustment screw assembly 3 on the spring adjustment sleeve 4, the displacement thrust of the return spring 5 acting on the top tightening beam 12, that is, the clamping force of the rear model when the mold is closed, can be adjusted.

[0034] The free end of the optical axis is placed outside the sliding ear, and an end stopper is installed at the end of the optical axis, and the end stopper cooperates with the sliding ear in a limited manner. The end stopper 1 fixedly installed at the end of the top beam slide 6 plays a role of insurance to prevent slipping.

[0035] The locking mechanism includes a locking cylinder 8 and a top tightening plate group 10. The top tightening plate group is two rectangular plates with two mounting holes, respectively, which are placed on the upper and lower surfaces of the connection between the top tightening beam fork body and the side model. One side of the top tightening plate group 10 is connected to the top tightening beam fork body through the locking cylinder 8, and the locking cylinder is placed on the upper side of one side of the top tightening plate group, and the extended end of the cylinder is slidably matched with the mounting hole of the top tightening plate group. The other side of the top tightening plate group 10 is connected to the side model through the connecting plate pin 11.

[0036] As a preferred solution, the locking mechanism further includes a telescopic pin 9. The telescopic pin is installed at the end of the telescopic rod of the locking cylinder, and the telescopic pin is placed in the mounting hole on the top tightening plate group and the two are slidably matched. When the telescopic rod of the locking cylinder is fully extended, the telescopic pin 9 extends into the pin hole at the bottom of the top tightening plate group 10, ensuring that the telescopic pin 9 will not damage the locking cylinder 8 when subjected to tangential force.

[0037] At least two tensioning beam slide seats are arranged in parallel on the tensioning beam. In this embodiment, a set of locking mechanisms are respectively arranged on the two tensioning beam fork bodies, and two sets of tensioning mechanisms are arranged on the upper surface of the tensioning beam body.

[0038] When the rear mold 15 and the side mold 16 are in the mold-clamping state, the locking cylinder 8 extends, driving the telescopic pin 9 installed at the end of the piston rod to pass through the connecting hole of the top tightening beam 12 and extend into the pin hole at the bottom of the top tightening connecting plate group 10, so as to realize the locking positioning of the top tightening beam 12 relative to the side mold 16 (see Figure 1 ).

[0039] Tightening of the rear model 15: The tightening oil cylinder 13 extends, and the tightening force is transmitted to the rear model 15 through the rear model mounting base plate 14, so that the rear model 15 and the side model 16 are closely fitted. Since the telescopic pin 9 bears the tangential force from the tightening connecting plate group 10 and the tightening beam 12, it effectively avoids damage to the locking cylinder 8. When used for a long time, only the telescopic pin needs to be replaced regularly, which reduces the maintenance cost.

[0040] The rear model 15 is released from the jacking and locking: the piston rod of the jacking cylinder 13 is retracted, and the piston rod of the locking cylinder 8 drives the telescopic pin 9 to retract, thereby releasing the lock with the jacking beam 12.

[0041] In order to ensure that the telescopic pin 9 can be flexibly retracted without being affected by the combined friction of the tightening connecting plate group 10 and the tightening beam 12, it is necessary to make appropriate displacement of the tightening beam 12 in the tightening direction when the piston rod of the tightening oil cylinder 13 is unloaded and compressed: loosen the fixing screw of the limit sleeve 2, slide the tightening beam 12 into place (the telescopic pin 9 can run flexibly without obstruction), and fix the limit sleeve 2. The displacement thrust of the return spring 5 acting on the tightening beam 12 can be adjusted through the adjusting screw combination 3 on the spring adjusting sleeve 4.

[0042] Due to factors such as the structural strength of the side model 16, the heights of the installation positions provided by the side models 16 of different height sizes for the top tightening plate group 10 are not the same. To ensure that the top tightening beam 12 accurately extends into the engagement position with the top tightening plate group 10, the height of the top tightening beam slide 6 together with the top tightening beam 12 can be adjusted by adjusting the bolt 7.
