Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a two-in-one fixture for taking and placing products by a robot and for shaping. Background Art

[0002] For round barrel-shaped products, due to the influence of comprehensive factors such as product structure and mold design, the mouth of the product has concave or outward deformation. After forming, the product has outward deformation in the X-axis direction and becomes elliptical. The true roundness is about 0.8MM, but the true roundness of this product is required to be less than or equal to 0.15.

[0003] Since the injection molding process cannot completely solve the problem of product deformation, it needs to be corrected through auxiliary fixtures. The original traditional practice is that after the injection molding is taken out by the robot, it is manually placed on the internal support shaping fixture, and after the timed removal, it enters the next process to correct the deformation size. Therefore, this plan proposes a two-in-one fixture for robot picking and placing products and shaping, combining removal and shaping into one. Utility Model Content

[0004] The utility model aims at least to solve the problem in the prior art that the work of taking out and shaping the round barrel-shaped product is performed separately by different tools.

[0005] This solution provides a two-in-one jig for picking up and placing products and shaping by a robot, which is achieved by the following specific technical means: it includes a top frame arranged above the mold, on which a mechanical claw is arranged, and the mechanical claw faces the molding groove on the mold, and at the same time, an orthotic part is arranged on the top frame, and after the mechanical claw lifts the barrel-shaped product out of the molding groove, it will enter the orthotic mouth of the orthotic part, and the orthotic part is used to correct the roundness.

[0006] Preferred technical solution 1: A fixed rail is fixed on the top frame, and the orthotic parts are symmetrically slidably arranged at both ends of the fixed rail and located on both sides of the forming groove. The two groups of orthotic parts are approached to each other to clamp and hug the two ends of the deformed protrusions of the product for shaping.

[0007] Preferred technical solution 2: Slide blocks are fixed to the ends of the two groups of orthopedic parts, and the distance between the two groups of orthopedic parts can be regulated by sliding the two groups of slide blocks in the fixed rails.

[0008] Preferred technical solution three: A control cylinder is installed on the fixed rail, and the control cylinder is used to control the distance between the two groups of sliders.

[0009] Preferred technical solution four: the mechanical claw sucks the product through a suction cup installed at the bottom.

[0010] Preferred technical solution five: The morphological structure of the two groups of orthopedic parts close to each other is adapted to the curvature of the outer wall of the product.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] 1. The fixture function is integrated to eliminate redundant and repetitive processes and save production time;

[0013] 2. It is highly versatile and can be used in a recycling manner with products of the same type, thus reducing waste of resources;

[0014] 3. Because of the timeliness of fixture shaping, the product forming quality can be ensured to be stable and the production efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 3The two-in-one fixture for picking up and placing products and shaping by a robot comprises a top frame 1 arranged above a mold 3, a mechanical claw 2 is arranged on the top frame 1, and the mechanical claw 2 is a telescopic mechanical claw 2. The mechanical claw 2 is directly opposite to the molding groove 31 on the mold 3. After the barrel-shaped product in the molding groove 31 is formed, the barrel-shaped product is taken out of the molding groove 31 by telescoping the mechanical claw 2. The mechanical claw 2 absorbs the barrel-shaped product through a suction cup 21 installed at the bottom. A fixed rail 5 is fixed on the top frame 1, and the fixed rail 5 is close to the molding groove 31 of the mold 3. Two groups of orthopedic parts 4 slide symmetrically in the fixed rail 5, and the two groups of orthopedic parts 4 are located on both sides of the molding groove 31. After the barrel-shaped product is taken out of the molding groove 31, the mechanical claw 2 enters the orthopedic mouth of the two groups of orthopedic parts 4, and the two groups of orthopedic parts 4 are close to each other to clamp and hug the two ends of the elliptical barrel-shaped product to correct the roundness.

[0022] See also Figure 1 The robot picks up and places the product and the two-in-one plastic surgery fixture. The two groups of orthopedic parts 4 are fixed with sliders 41 at the ends. The two groups of sliders 41 slide in the fixed rails 5 to adjust the distance between the two groups of orthopedic parts 4. A control cylinder is installed on the fixed rails 5. The two telescopic ends of the control cylinder are respectively connected to the two groups of sliders 41 for controlling the distance between the two groups of sliders 41.

[0023] See also Figure 1 The robot takes and places the product and the two-in-one jig for plastic surgery. Correction blocks are fixed on the inner sides of the two groups of orthopedic parts 4. The correction blocks and the orthopedic parts 4 can be removably assembled. The correction blocks on the two groups of orthopedic parts 4 are all concave arc structures on the sides close to each other. The concave arc adapts to the arc of the outer wall of the barrel-shaped product to ensure that the barrel-shaped product can fit better when it is hugged for correction. At this time, the barrel-shaped product has just been taken out of the molding groove, the temperature is relatively high, and it has greater plasticity. The orthopedic parts 4 are timely hugged and corrected at this time, because the product is hugged and shaped in the shortest time, so the product molding is stable and the injection molding production efficiency is improved.

[0024] See also Figure 1 The two-in-one jig for picking up and placing products and shaping products by the robot is suitable not only for round barrel-shaped products, but also can be extended to other square and rectangular products with similar deformation problems by changing the correction block, and can be expanded for use horizontally; because the separately made shaping jig is eliminated, the cost is not increased, but the production efficiency is improved.

[0025] By reserving an interference fit between the two sets of sliders 41, products of the same type with similar dimensions can be modified and reused in a circular manner, thereby saving a certain amount of fixture cost.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
