Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, and more specifically, to a fully automatic quick assembly and disassembly structure for the bottom mold. Background Technology

[0002] In the production process of blow molding dies, especially for the needs of multi-variety, small-batch production, frequent die changes are required. As a crucial component of blow molding dies, the efficiency of its installation and disassembly directly impacts the changeover time and production efficiency of the entire production line. Existing die bases are typically connected to the blow molding machine's worktable or die frame using bolts. This method has the following drawbacks: First, the installation and disassembly process is cumbersome, requiring the use of wrenches and other tools to tighten or loosen multiple bolts one by one, consuming a significant amount of time and resulting in excessive downtime. Second, the operation is labor-intensive and inconvenient in confined spaces, easily leading to bolt stripping or loss. Third, repeated bolt disassembly and assembly can cause thread wear, affecting the reliability of the connection and positioning accuracy, which may ultimately affect the quality of the final product.

[0003] Therefore, developing a mold bottom mold assembly and disassembly structure that can achieve rapid and accurate positioning and reliable locking, in order to shorten mold change time, reduce labor intensity and improve production efficiency, is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The present invention provides a fully automatic quick assembly and disassembly structure for mold bottom molds to solve the problems of long assembly and disassembly time, high labor intensity and low efficiency in the prior art.

[0005] The technical solution adopted by this utility model is as follows: A fully automatic quick-assembly and disassembly structure for mold bottom mold, characterized in that it includes: The bottom mold body is provided with a sliding cavity, and the top and bottom of the sliding cavity are respectively provided with a coaxial upper section positioning hole and a lower section positioning hole; A limiting block is slidably installed in the sliding cavity. The limiting block has a circular through hole that passes through it. The circular through hole includes a circular part and a groove part at the edge of the through hole. And an elastic element, used to apply an elastic thrust to the limiting block; When the limiting block is slid to the first position by the force of the elastic element, the circular part of the through hole, the upper positioning hole and the lower positioning hole are coaxially aligned to form an insertion hole for the machine guide pin to pass through; when the external force is released, the limiting block rebounds to the second position under the action of the elastic element, the groove part of the through hole edge moves to the insertion hole to secure the machine guide pin.

[0006] Furthermore, a limiting post is fixedly provided in the sliding cavity of the bottom mold body, and the limiting block is provided with a strip-shaped limiting hole for the limiting post to pass through and be guided.

[0007] Furthermore, the elastic element is disposed between the innermost end of the limiting block within the sliding cavity and the innermost part of the sliding cavity.

[0008] Furthermore, the elastic element is a compression spring.

[0009] Compared with the prior art, the beneficial effects of this utility model are: (1) Alignment is achieved by pushing in the limiting block, and automatic locking is achieved by the rebound force of the elastic element after releasing. The whole process does not require any tools, realizing quick installation and disassembly in the form of "one push and one release". Compared with the traditional bolt fixing method, it greatly shortens the replacement time of the bottom mold, significantly reduces the downtime of production equipment, and thus improves the overall production efficiency.

[0010] (2) By matching the upper and lower positioning holes with the round part of the through hole on the limit block, the machine guide pin can be accurately guided to insert, ensuring the installation accuracy of the bottom mold. After the limit block is released, the slot of the through hole edge automatically engages in the groove of the guide pin. The continuous pressure provided by the elastic element achieves stable and reliable locking, avoiding loosening caused by vibration and other reasons, and ensuring the stability of the production process and product quality.

[0011] (3) The overall structure is compact, with fewer parts and clear motion relationships, which reduces manufacturing costs and failure rate. Since there are no easily worn threaded parts, its service life is longer and maintenance is simpler and more convenient, effectively reducing the company's operating and maintenance costs.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0016] Reference Figures 1 to 4 This utility model provides a fully automatic quick assembly and disassembly structure for mold bottom mold, including: bottom mold body 1), lower section positioning hole 2, upper section positioning hole 3, sliding cavity 4, limiting block 5, through hole circular part 6, through hole edge groove part 7, limiting post 8, elastic element 9 and strip-shaped limiting hole 10.

[0017] Specifically, the bottom mold body 1 is the basic component that supports the entire assembly and disassembly structure. A horizontal sliding cavity 4 is provided inside the bottom mold body 1. An upper positioning hole 3 and a lower positioning hole 2 are machined at the top and bottom of the sliding cavity 4, respectively, and the axes of the upper positioning hole 3 and the lower positioning hole 2 coincide with each other, together forming a reference hole for installation positioning.

[0018] The limiting block 5 is a core moving component, slidably assembled inside the sliding cavity 4. A circular through-hole is formed on the limiting block 5, penetrating its upper and lower surfaces. This circular through-hole is not a simple cylindrical hole, but consists of two parts: a larger diameter circular portion 6 and a smaller diameter edge groove 7 formed on one side edge of the through-hole. Furthermore, the limiting block 5 also has a strip-shaped limiting hole 10 extending through its sliding direction.

[0019] To guide and restrict the movement of the limiting block 5, a limiting post 8 is fixedly installed inside the sliding cavity 4. This limiting post 8 is vertically positioned, with its upper end fixed to the top inner wall of the sliding cavity 4 and its lower end fixed to the bottom inner wall of the sliding cavity 4, passing through the strip-shaped limiting hole 10 of the limiting block 5. The cooperation between the limiting post 8 and the strip-shaped limiting hole 10 ensures that the limiting block 5 can only perform reciprocating linear motion within the sliding cavity 4, and its stroke is limited by both ends of the strip-shaped limiting hole 10.

[0020] To achieve automatic locking, an elastic element 9, such as a compression spring, is also provided in the structure. This elastic element 9 is placed between the innermost end of the limiting block 5 in the sliding cavity 4 and the innermost inner wall of the sliding cavity 4. The elastic element 9 always applies an outward elastic thrust to the limiting block 5, causing it to tend to move to the outermost position when no external force is applied.

[0021] The working process of this utility model is as follows: Installation process (first working state, such as...) Figure 1 and Figure 2 (as shown) When the bottom mold needs to be installed onto the blow molding machine, the operator manually or using an automated device pushes the limit block 5 inward (e.g., ...). Figure 1 (As indicated by the arrow), overcoming the elastic force of the elastic element 9, the limiting block 5 slides into the sliding cavity 4 under the guidance of the limiting post 8 until it reaches its innermost position (i.e., the first position). At this position, the perfectly round part 6 of the through hole of the limiting block 5 is exactly coaxially aligned with the upper positioning hole 3 and the lower positioning hole 2 of the bottom mold body 1. At this time, these three together form a smooth and unobstructed insertion hole. Subsequently, the insertion hole can be inserted into the machine's guide pin (not shown in the figure) to complete the initial positioning of the bottom mold.

[0022] Automatic locking process (second working state, such as...) Figure 3 and Figure 4 (as shown) Once the machine guide pin is fully inserted, the external force applied to the limit block 5 is released. Under the pre-stored elastic force of the elastic element 9 (such as...), Figure 3 As indicated by the arrow, the limiting block 5 will automatically spring back outward and slide to its outermost position (i.e., the second position). Its movement is restricted by the limiting post 8 at the other end of the strip-shaped limiting hole 10. During this sliding process, the circular part 6 of the through hole is misaligned with the upper and lower positioning holes 3 and 2, while the smaller diameter edge groove part 7 of the through hole moves to the position of the guide pin and accurately engages with the pre-set annular groove on the guide pin. Through the engagement of the edge groove part 7 of the through hole and the guide pin, reliable locking and fixing of the bottom mold is achieved.

[0023] Disassembly process: When disassembling the bottom mold, the process is the reverse of the installation. Simply push the limiting block 5 inward to its innermost position again, so that the circular part of the through hole 6 is aligned with the guide pin, and release the jamming state. Then, the mold can be easily pulled upward from the guide pin, completing the quick disassembly of the bottom mold.

[0024] In summary, this utility model simplifies the complex bolt fixing operation into a simple push and loose action through ingenious mechanical structure design, realizing the rapid, accurate, and reliable assembly and disassembly of the bottom mold, and greatly improving production efficiency.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
