DETAILED DESCRIPTION

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a leather and plastic product cold pressing forming machine of the utility model comprises a panel 1, a lower cold pressing template 2 and an upper cold pressing template 3, wherein the lower cold pressing template 2 and the upper cold pressing template 3 are arranged on the panel 1, and the upper cold pressing template 3 is arranged above the lower cold pressing template 2. An adjusting groove 6 is arranged in the middle of the panel 1, and an adjusting block 9 is installed on the bottom surface of the lower cold pressing template 2 opposite to the adjusting groove 6. The adjusting block 9 is slidably arranged in the adjusting groove 6, and a screw hole is provided on the adjusting block 9. A screw 10 is threadedly connected in the screw hole. One end of the screw 10 extends to the outside of the adjusting groove 6 and is installed with a gear 11. A linkage mechanism for driving the gear 11 to rotate and synchronously moving the lower cold pressing template 2 is installed on one side of the gear 11.

[0023] In this embodiment, the linkage mechanism includes a positioning rod 16, a moving rod 14, a positioning bar 17 and a plurality of convex teeth 15. The moving rod 14 is arranged on one side of the gear 11, and the plurality of convex teeth 15 are installed on one side surface of the moving rod 14, and the convex teeth 15 are arranged toward the gear 11, and the uppermost convex teeth 15 are arranged without contact with the gear 11. The positioning rod 16 is installed on the panel 1, and the positioning rod 16 is arranged close to the moving rod 14. A positioning groove is vertically arranged on one side surface of the positioning rod 16, and the positioning bar 17 is slidably arranged in the positioning groove. One side of the positioning bar 17 is installed on the moving rod 14, and the cross-section of the positioning bar 17 and the positioning groove is arranged in a "T"-shaped structure;

[0024] The moving rod can be positioned by the positioning rod and the positioning groove, so that the moving rod can only move up and down along the positioning groove, thereby avoiding the dislocation and deviation of the moving rod and increasing the stability.

[0025] In this embodiment, the panel 1 is provided with slide grooves 5 on both sides of the adjustment groove 6, and sliders 12 are installed on the bottom surface of the lower cold pressing template 2 opposite to the slide groove 5. The sliders 12 are slidably set in the slide groove 5. The cross-sections of the sliders 12 and the slide groove 5 are both trapezoidal structures. The lower cold pressing template can be positioned by the sliders and the slide groove, so that the lower cold pressing template can only move forward and backward along the slide groove to avoid displacement.

[0026] In this embodiment, a baffle 13 is installed on one side of the panel 1 to block the opening of one end of the slide groove 5 .

[0027] In this embodiment, a bearing 7 is installed at one end of the screw rod 10 away from the gear 11, and a fixed seat is installed between the bearing 7 and the adjustment groove 6. The other end of the screw rod can be fixed by the bearing to avoid affecting the stability of the screw rod.

[0028] In this embodiment, a base 8 is installed on the bottom surface of the panel 1, and the panel can be suspended by the base so that the bottom of the moving rod does not contact the ground.

[0029] In this embodiment, the length of the upper cold pressing template 3 is greater than that of the lower cold pressing template 2. Positioning holes are provided on the four corners of the upper cold pressing template 3. Positioning columns 4 are provided in the positioning holes. The lower ends of the positioning columns 4 are installed on the panel 1. The upper cold pressing template 3 is provided with a plurality of fixing holes for fixing to the cylinder.

[0030] The piston rod of the cylinder is installed on the top surface of the upper cold pressing template through a connecting flange. After the leather plastic product is cold pressed, the cylinder can be started to retract the piston rod of the cylinder. The movement of the piston rod drives the upper cold pressing template, so that the upper cold pressing template is stable along the upper body of the positioning column. When it starts to move upward, the convex teeth on the moving rod have not yet meshed with the gear. Therefore, the movement of the upper cold pressing template will not drive the movement of the lower cold pressing template, so that the upper cold pressing template will be separated from the leather plastic product first. With the continued movement, the convex teeth can drive the rotation of the gear. The rotation of the gear synchronously drives the screw rod, and the rotating screw rod can drive the adjusting block. The movement of the adjusting block drives the lower cold pressing template, so that the lower cold pressing template moves outward along the slide groove, thereby displacing the upper cold pressing template and the lower cold pressing template, so that the staff does not need to extend their hands between the upper and lower cold pressing templates, and can directly disassemble the leather plastic product on the lower cold pressing template from the outside;

[0031] On the contrary, after the upper cold pressing template moves downward, the convex teeth can drive the gear and the screw to rotate in the opposite direction, thereby driving the lower cold pressing template to return along the slide groove until it contacts the baffle, and the convex teeth will disengage from the gear, so that the upper cold pressing template still has a downward pressing distance to complete the cold pressing operation on the leather and plastic products.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
