Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses an open press, including workstation 1, frame 2 of rigid coupling on workstation 1, drift 21 of sliding connection on frame 2, can dismantle the bed die 3 of connection on workstation 1 and the last mould 4 of rigid coupling on drift 21, there is supplementary mounting panel 5 at one side rigid coupling of bed die 3 towards workstation 1, is provided with the locating component 6 of fixed supplementary mounting panel 5 relative position on workstation 1 between supplementary mounting panel 5 and workstation 1.

Referring to fig. 2, the positioning assembly 6 includes a first slider 61 of which the cross section is in an inverted T shape and which is fixedly connected to the auxiliary mounting plate 5 and away from one side of the lower mold 3, a first chute 62 of which the cross section is in an inverted T shape and which is used for sliding the first slider 61 is provided at two ends of the workbench 1, a second chute 63 of which the cross section is in an inverted T shape and which is vertically communicated with the first chute 62 is also provided on the workbench 1, a second slider 64 is slidably connected to the second chute 63, a first spring 65 is further placed between one end of the second chute 63 away from the first chute 62 and the second slider 64, and a positioning groove 66 of which the second slider 64 is embedded is provided at one side of the auxiliary mounting plate 5 facing the second chute 63. The second slide block 64 is inserted into the positioning slot 66 under the action of the first spring 65 to fix the relative position of the auxiliary mounting plate 5 in the first sliding slot 62.

Referring to fig. 2 and 4, in order to prevent the second slider 64 from being separated from the positioning groove 66 against the elastic force of the first spring 65 by an external force, the auxiliary mounting plate 5 is slid to affect the normal operation. A fixing component 7 is arranged between the second sliding block 64 and the positioning slot 66, and the fixing component 7 comprises a placing groove 71 arranged on two opposite sides of the second sliding block 64, a wedge block 72 connected in the placing groove 71 in a sliding manner, a second spring 73 fixedly connected between the closed end of the placing groove 71 and the wedge block 72, and an embedding groove 74 arranged on two opposite side walls of the positioning slot 66 and used for embedding the wedge block 72. With the wedge block 72 sloping away from the side of the first spring 65. When the second slider 64 is inserted into the positioning groove 66 by the first spring 65, the inclined edge of the wedge 72 is pressed by the auxiliary mounting plate 5 and retracted into the placement groove 71, and after the second slider 64 slides into the positioning groove 66, the wedge 72 also extends out of the placement groove 71 and is inserted into the insertion groove 74 by the second spring 73, so that the relative position of the second slider 64 and the auxiliary mounting plate 5 is fixed.

Referring to fig. 2 and 3, the fixing assembly 7 further includes a pulling rope 75 fixedly connected to one end of the wedge block 72 facing the second spring 73, and meanwhile, an installation groove 76 is further opened on the upper surface of the second slider 64, an installation post 77 is slidably connected to the installation groove 76, a third spring 78 is fixedly connected between the closed end of the installation groove 76 and the installation post 77, and one end of the pulling rope 75 far away from the wedge block 72 penetrates between the closed end of the placing groove 71 and the installation groove 76 and is fixedly connected with the installation post 77. Normally, the mounting post 77 extends out of the mounting groove 76 under the action of the third spring 78, the wedge block 72 is also embedded into the embedding groove 74 under the action of the second spring 73, when the worker presses the mounting post 77 externally, the mounting post 77 retracts into the mounting groove 76 and compresses the third spring 78, and meanwhile, the pulling rope 75 is also driven to pull the wedge block 72 to retract into the placing groove 71 and press the second spring 73, so that the matching relation between the second sliding block 64 and the auxiliary mounting plate 5 is released.

Preferably, in order to avoid the stay cord 75 from being jammed between the mounting post 77 and the positioning groove 66 when the mounting post 77 slides between the mounting post 77 and the inner wall of the positioning groove 66, thereby affecting the normal operation, the diameter of the mounting post 77 is set to be smaller than that of the mounting groove 76, and a gap for the stay cord 75 to slide is left between the mounting post 77 and the mounting groove 76. Simultaneously there are two card strips 771 along its length direction rigid coupling on erection column 77, two card strips 771 set up along 77 axis symmetry of erection column, offer the gliding third spout 761 of confession card strip 771 on 76 inner walls of mounting groove along its length direction, card strip 771 can play the effect of direction to erection column 77, simultaneously because the card strip 771 of two symmetries all with third spout 761 tank bottom butt, so also can restrict the relative position of erection column 77, make erection column 77 axis and 76 axis coincidence of mounting groove, avoid erection column 77 to take place the slope in mounting groove 76.

Meanwhile, in order to prevent dust from falling into the mounting groove 76 from a gap between the mounting post 77 and the mounting groove 76, a baffle 79 is further fixedly connected to an opening of the mounting groove 76.

Referring to fig. 2, handles 51 are further fixedly connected to both ends of the auxiliary mounting plate 5 to facilitate the worker to take off the mold 3.

To sum up, during installation, the worker can directly hold the handle 51, so that the first sliding block 61 slides into the first sliding groove 62, and simultaneously the second sliding block 64 is made to press the first spring 65 at the position of the second sliding groove 63, when the auxiliary mounting plate 5 slides to the second sliding groove 63, the second sliding block 64 is released, and the second sliding block 64 abuts against one side of the auxiliary mounting plate 5 under the action of the first spring 65. Then, the auxiliary mounting plate 5 is slid further until the positioning groove 66 is flush with the second sliding groove 63, the second sliding block 64 is also inserted into the positioning groove 66 by the first spring 65, and the wedge block 72 is also inserted into the insertion groove 74 by the second spring 73, so that the relative position of the lower mold 3 is fixed, and the mounting work is completed.

When the lower die 3 needs to be replaced, a worker directly presses the mounting post 77 with one hand at the outside, the mounting post 77 drives the pulling rope 75 to slide in the mounting groove 76 and press the third spring 78, the pulling rope 75 also pulls the wedge block 72 to retract into the placing groove 71 and press the second spring 73, and the worker can directly slide the second sliding block 64 to slide out of the positioning groove 66 and press the first spring 65 with one hand pressing the mounting post 77. Then, the worker directly pulls the handle 51 with the other hand to slide the first sliding block 61 in the first sliding groove 62, so as to remove the auxiliary mounting plate 5 and the lower mold 3 fixed on the auxiliary mounting plate 5. When the second sliding block 64 is released, the second sliding block 64 slides towards the first sliding groove 62 under the action of the first spring 65, the wedge block 72 also extends out of the placing groove 71 under the action of the second spring 73, and the mounting column 77 slides in the mounting groove 76 and extends out of the mounting groove 76 again under the combined action of the third spring 78 and the pull rope 75 to wait for the next mounting work.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
