DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0019] like Figures 1 to 4 As shown, the utility model provides a clamp for fixing a side mold core, comprising a main body 1, a mold core 2, a side panel 3 arranged on the main body 1, and a plurality of clamping mechanisms 4 each provided with a side panel 3, wherein the plurality of clamping mechanisms 4 cooperate to fix the mold core 2 to the side panel 3, the main body 1 is provided with three positioning pins 5 and at least two fixing nails 6, the mold core 2 is provided with three positioning holes 7 and two fixing holes 8, the three positioning holes 7 are respectively located at three corners of the mold core 2, the three positioning pins 5 are installed in one-to-one correspondence with the three positioning holes 7; the fixing nails 6 are screwed into the fixing holes 8.

[0020] Specifically, when installing the core mold 2 to the side panel 3, the core mold 2 is actually erected and kept suspended in the air. Therefore, it is necessary to first match the three positioning holes 7 of the core mold 2 with the three positioning pins 5 of the side panel 3 one by one and assemble them, and realize reliable positioning of the corresponding core mold 2 by three-point positioning; then use the clamping mechanism 4 to resist the core mold 2 and move the core mold 2 toward the positioning pin 5, press the core mold 2 to the positioning pin 5 to ensure that the positioning pin 5 is reliably inserted into the core mold 2; and then fix the core mold 2 to the side panel 3 by screwing the fixing nail 6 to the core mold 2.

[0021] The utility model has a simple structure and realizes the effect that the mold core 2 that is erected and suspended can also be replaced, thereby saving costs.

[0022] In this embodiment, the side panel 3 is provided with a first mounting hole 9 and a second mounting hole 10. The fixing nail 6 is screwed into the first mounting hole 9, and the positioning pin 5 is screwed into the second mounting hole 10. That is, both the fixing nail 6 and the positioning pin 5 are screwed into the side panel 3, thereby ensuring that both the fixing nail 6 and the positioning pin 5 remain perpendicular to the side panel 3, preventing the tips of the fixing nail 6 and the positioning pin 5 from sinking and affecting the positioning and fixing of the mold core 2.

[0023] In this embodiment, two of the positioning pins 5 are located above the other positioning pin 5. That is, the line connecting the three positioning pins 5 forms a right triangle, and the two right-angled sides of the right triangle are located at the top and one side respectively. The two positioning pins 5 cooperate to achieve the effect of "hanging" the mold core 2, so the positioning effect of the mold core 2 is better than the method of two positioning pins 5 being located below each other.

[0024] In this embodiment, at least two fixing pins 6 are not all located on the same vertical line. Figure 1 There are two fixing nails 6 shown, and the two fixing nails 6 are staggered with each other, thereby realizing a fool-proof function and preventing the mold core 2 from being installed upside down.

[0025] In this embodiment, a reinforcement 11 is provided between the main body 1 and the side panel 3. The cross-sectional shape of the reinforcement 11 is a right-angled trapezoid, which plays the role of supporting the side panel 3, thereby keeping the side panel 3 in an upright state, and further allowing the core 2 to stably maintain an upright state.

[0026] In this embodiment, the clamping mechanism 4 includes a cylinder 12 and a clamping member 13. The cylinder body of the cylinder 12 has a mounting portion 14, and the side plate 3 is provided with a through hole 15 for mounting the mounting portion 14. The clamping member 13 is mounted on the piston rod of the cylinder 12 and is used to contact the mold core 2. The clamping mechanism 4 uses the cylinder 12 as a driving source to drive the clamping member 13 toward or away from the positioning pin 5 to clamp and release the mold core 2. The action is simple and easy to control.

[0027] Specifically, the cylinder 12 is a rotary clamping cylinder 12, that is, the piston rod of the cylinder 12 will rotate after the core 2 is released, thereby making way for the core 2 and avoiding interference with the replacement of the core 2.

[0028] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
