Description

Technical Field

[0001] This utility model relates to the field of thermoforming technology, specifically a thermoforming mold for a turtle toy. Background Technology

[0002] Hot pressing is a common processing method in the plastics processing industry. It mainly involves heating and processing the mold, placing the mold blank in it, and using pressure to fix the mold blank between the male and female molds. The melting temperature and time of the mold blank are controlled. After the mold blank melts, hardens, and cools, it is demolded and the molded product can be taken out.

[0003] For products with simple structures, such as edgeless basins, demolding can be achieved simply by ejecting the product directly through the ejection mechanism after the parent and parent molds separate. However, for products with complex structures, such as turtle toys, whose shapes are varied and intricate, multiple modules are needed to clamp the turtle model blank together to cooperate with the parent and parent molds in hot-pressing the turtle model blank. This leads to a problem: when demolding the aforementioned turtle toy molding mold, after the parent and parent molds are separated, the clamping modules need to be further separated from the turtle model manually or by other powered mechanisms (such as cylinders). Manual operation results in low production efficiency, high labor intensity, and excessively high labor costs; while using a powered mechanism for demolding undoubtedly increases mold costs and thus production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a thermoforming mold for turtle toys, which can open the two core molds while separating the parent mold and the mother mold, thereby enabling the turtle model product to be demolded quickly, improving production efficiency and reducing production costs, so as to solve the problems of low production efficiency and high production cost of existing turtle toy molding molds mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0026] Please see Figure 1-4A thermoforming mold for a turtle toy includes a clamping frame 1, a female mold 2 movably disposed within the clamping frame 1, and a male mold 3 pressed against the top surface of the female mold 2. The top surface of the female mold 2 is provided with several lower forming grooves 21, and the bottom surface of the male mold 3 is provided with an mounting groove 31. The top surface of the mounting groove 31 is provided with several upper forming grooves 32 adapted to the lower forming grooves 21. Two relatively movable core molds 4 are provided on both sides of the lower forming grooves 21 on the top surface of the female mold 2. The two core molds 4 are housed within the mounting grooves 31, and their opposing surfaces are respectively provided with clamping grooves 41. The end face of the clamping frame 1 has two V-shaped guide grooves 11, and the end faces of the two core molds 4 are respectively provided with two guide slides 5 housed in the corresponding guide grooves 11. In this embodiment, the clamping frame 1 has a square frame structure.

[0027] Please see Figure 1-2 as well as Figure 6 When the mold is opened, the father mold 3 moves upward relative to the clamping frame 1, and the mother mold 2 moves downward relative to the clamping frame 1, so that the two guide slides 5 move obliquely downward along the guide groove 11, thereby driving the two core molds 4 to open. Then, the turtle blank is placed in the lower forming groove 21, the mother mold 2 moves upward relative to the clamping frame 1, and the two guide slides 5 move obliquely upward along the guide groove 11, thereby driving the two core molds 4 to hold the turtle blank. Then, the father mold 3 moves downward to close with the mother mold 2 for hot pressing. After the hot pressing process is completed, the father mold 3 moves upward relative to the clamping frame 1, and the mother mold 2 moves downward relative to the clamping frame 1, so that the two core molds 4 open and detach from the turtle model product, thereby achieving rapid demolding and improving production efficiency. This embodiment uses the ingenious design between the guide groove 11 and the guide slides 5 to replace the existing method of manually or using a power device to open the core molds 4, saving labor or power device costs and thus reducing production costs.

[0032] In this embodiment, the top edges of the two core molds 4 are respectively provided with interconnected upper receiving grooves 43, and the second protrusion 33 is received in the two upper receiving grooves 43; the bottom edges of the two core molds 4 are respectively provided with interconnected lower receiving grooves (not shown in the figure), and the first protrusion 23 is received in the lower receiving groove. In this embodiment, the clamping groove 41 is connected to the upper receiving groove 43 and the lower receiving groove to allow the turtle blank to pass through, and the sidewall of the clamping groove 41 is provided with a shape adapted to the shape of the turtle blank.

[0033] Please see Figure 3 and Figure 7 The bottom wall of the lower forming groove 21 has a slot 24, and a forming insert 6 is disposed in the slot 24. The forming insert 6 includes a lower insert 61 accommodated in the slot 24 and an upper insert 62 connected to the top of the lower insert 61. The upper insert 62 extends through the lower receiving groove to the clamping groove 41 and the upper receiving groove 43, and is used to cooperate with the upper forming groove 32 to press the turtle blank. The edge of the turtle blank is placed in the lower forming groove 21. In this embodiment, the top surface of the upper insert 62 is provided with a plurality of evenly distributed protrusions, and the upper forming groove 32 is provided with a plurality of grooves that adapt to the protrusions.

[0034] Please refer to Figure 3 and Figure 5 The bottom wall of the slot 24 has a through hole 25 extending to the bottom surface of the mother mold 2. Please refer to [link / reference]. Figure 7 The bottom surface of the lower insert 61 is provided with a slot 611, and an ejector insert 7 is inserted into the slot 611, which extends through the through hole 25 to the bottom of the female mold 2.

[0036] The working principle of the thermoforming mold for a turtle toy of this utility model is as follows: Please refer to... Figure 1-2 as well as Figure 6 When the mold is opened, the father mold 3 moves upward relative to the clamping frame 1, and the mother mold 2 moves downward relative to the clamping frame 1, so that the two guide wheels 52 move diagonally downward along the guide groove 11 and drive the two core molds 4 to open. Then, the turtle blank is placed on the upper insert 62 in the lower forming groove 21. The mother mold 2 moves upward relative to the clamping frame 1, and the two guide slides 5 move diagonally upward along the guide groove 11 and drive the two core molds 4 to move axially along the guide rail 22 until the two core molds 4 clamp the turtle blank. Then, the father mold 3 moves downward to close with the mother mold 2 and perform hot pressing. After the hot pressing process is completed, the father mold 3 moves upward relative to the clamping frame 1, and the mother mold 2 moves downward relative to the clamping frame 1, so that the two core molds 4 open and detach from the turtle model product. Finally, the turtle model after the turtle blank is formed is ejected from the lower forming groove 21 by the ejector insert 7, thereby achieving rapid demolding.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
