Specifically, each slider 23 is correspondingly provided with a limit block 8, and the limit block 8 is connected to the lower template 21 by a thread.

[0063] The working principle of a product support shaping fixture claimed for protection in an embodiment of the present invention is briefly described as follows: when in use, the product to be shaped is placed on the lower mold insert 22, and the product to be shaped is accurately stuck in the positioning groove 221; the upper mold 1 is pressed down for shaping, and at this time the slide 23 is driven by the shovel base 13 to move toward the direction close to the lower mold insert 22, thereby pressing the side surface of the product, and the upper mold insert 12 presses the upper surface of the product; the first driving member 4 drives the limiting guide post 3 to rise, and the limiting guide post 3 is transformed into a limiting state, and the top of the limiting guide post 3 in the limiting state is stuck in the slot 2311 of the slide 23, thereby limiting the relative position of the slide 23 and the lower mold insert 22, so that The slide 23 remains in a state of pressing against the product, and at the same time, the second driving member 5 drives the ejector 7 to rise, so that the top end of the ejector 7 is inserted into the hole structure of the product, thereby correcting the hole structure of the product; the upper mold 1 rises, and since the slide 23 is still pressing against the product at this time, the product will not stick to the upper mold insert 12 and move with the upper mold 1. At the same time, the second driving member 5 drives the ejector 7 to descend, so that the top end of the ejector 7 exits the hole structure of the product; after the mold opening is completed, the first driving member 4 drives the limiting guide post 3 to exit the slide groove 211, and the limiting guide post 3 is transformed into a retracted state. At this time, the slide 23 can move in the direction away from the lower mold insert 22, and the staff can remove the shaped product.

[0064] To sum up, the product holder shaping jig provided by the utility model shapes the product through the upper mold insert, lower mold insert and slide when the mold is closed, and uses the first driving member to drive the limit guide column to the limit state, so that the slide remains in the state of pressing the product, avoiding the product from sticking to the upper mold insert when the mold is opened and following the movement of the upper mold, thereby making it convenient for the staff to take the shaped product, which is conducive to saving manpower and improving efficiency.

[0065] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
