Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically a splicing plastic mold. Background Technology

[0002] Plastic is a material whose main component is polymer. When heated to a certain temperature, the plastic melts and can then be molded to fit into a mold. Different molds can be used to shape the plastic into different forms.

[0003] In the prior art, published on February 9, 2024 (publication date: CN220464588U), a modular plastic mold is proposed, including a base placed on the ground; it further includes: a limiting rod fixed to the top of the base, a top cover fixed to the top of the limiting rod, and a receiving block sliding on the limiting rod; the middle of the receiving block is connected to a hydraulic rod, and a first mold is disposed inside the receiving block; a second mold is placed on the top of the base; a moving block is attached to the bottom of the second mold, and the bottom of the moving block slides inside the base. This modular plastic mold is equipped with a clamping block. When the mold is placed on the base, the weight of the mold moves the moving block, which in turn moves the clamping block via a second pull rope, allowing the clamping block to hold the second mold, thus achieving rapid assembly and ensuring the second mold is centered, thereby reducing glue overflow.

[0004] In the aforementioned prior art, a lateral elastic fixing effect is formed by using a spring to press against the protrusion or the locking block. However, this lateral elastic fixing means that the locking block can still move left and right, resulting in poor stability. Therefore, a new type of splicing plastic mold is proposed to optimize the aforementioned prior art. Utility Model Content

The F-shaped support 28 is adapted to the baffle 27, and the baffle 27 can rotate and fall on the two steps of the F-shaped support 28 respectively.

[0032] Pull handle 26 allows for easy lifting of pull rod 14. With the help of baffle 27 and F-shaped support 28, the position and state of pull rod 14 can be easily controlled and maintained. This allows the triangular block 24 to be inserted into the triangular groove 25, directly maintaining the loosening of the locking and fixing of mold cavity 7, facilitating the disassembly of mold cavity 7. Alternatively, it can simply loosen the state of positioning block 21 inserted into positioning hole 22, loosening the restriction on connecting rod 12, facilitating the installation of mold cavity 7.

The mold as a whole is an assembly design.

[0037] The working principle of this utility model is as follows:

[0038] In use, pull the handle 26 and rotate it to place the baffle 27 on the first step of the F-shaped support 28. At this time, the mold cavity 7 can be placed corresponding to the cavity 6. The edge of the mold cavity 7 presses the plug 11, causing the spring 13 to contract, so that the mold cavity 7 can be inserted. Finally, the socket 9 corresponds to the plug 11. Under the action of the spring 13, the plug 11 is inserted into the socket 9 and fixed. Then, rotate the baffle 27 again to make the baffle 27 fall off the F-shaped support 28. At this time, under the action of gravity and the action of the tension spring 18, the pull rod 14 moves down along the direction of the positioning pin 17 and the guide cavity 16, thereby driving the positioning block 21 to be inserted into the positioning hole 22 through the first extension arm 20, so that the connecting rod 12 is laterally limited.

[0039] During disassembly, pull the handle 26 and rotate it to place the baffle 27 on the top step of the F-shaped support 28, so that the triangular block 24 is inserted into the triangular groove 25, thereby pushing the connecting rod 12, causing the slider 10 to pull the plug 11 out of the socket 9, so that the mold cavity 7 can be easily removed.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
