Description

Technical Field

[0001] The invention relates to the field of moulds, in particular to a diaphragm-type single-side small space spiral sliding composite action mould structure. Background Art

[0002] When some diaphragm-like products are injection molded by molds, in order to ensure the structural strength and connection of the products, the design of reinforcing ribs and connecting buckles are added to the sides of the products. The connecting buckles include connecting hooks or connecting hole structures. When the distance between the reinforcing ribs and the connecting buckles is small, it is difficult to design two automatic demoulding structures to demould the reinforcing ribs and the connecting buckles separately. Manual demoulding can only be performed by designing manual inserts, which affects production efficiency and is not conducive to the automated and efficient production of products. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a diaphragm-type single-side small space spiral sliding composite action mold structure which can simultaneously complete the automatic demoulding of reinforcing ribs and connecting buckles in a limited space.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is: a diaphragm-type single-sided small space spiral sliding compound action mold structure, including a main body, a straight plug and an ejection retraction block, a rib forming groove for local reinforcement ribs of the molded product is provided between the straight plug and the retraction block, during the demolding process, the straight plug first performs an ejection movement, and then drives the ejection retraction block to perform an ejection movement, the main body also includes a hole stripping component, the hole stripping component includes a molding rod for a connecting hole of the molded product, and the hole stripping direction of the molding rod is perpendicular to the ejection movement direction of the straight plug, during the demolding process, the straight plug drives the molding rod to perform a hole stripping movement through the hole stripping component during the ejection movement process.

[0005] Compared with the prior art, the advantages of the present invention are: through the design of the straight ejector head and the ejection retraction block forming a rib groove, it is easy to successfully demould the local reinforcing rib without damaging the reinforcing rib. At the beginning, during the ejection movement of the straight ejector head, the ejection retraction block will not move together, thereby forming a separation of the rib groove, and then when the reinforcing rib is demoulded, the reinforcing rib will not be damaged, thereby ensuring the molding quality of the reinforcing rib, and when the connecting hole is demoulded later, the straight ejector head has moved the product out, and the ejection retraction block is separated from the reinforcing rib, eliminating the movement interference between the ejection retraction block and the reinforcing rib, and the movement of the forming rod will not be impossible due to the connection between the ejection retraction block and the reinforcing rib. Finally, in one demoulding process and in a smaller space, the demoulding operation of the reinforcing rib and the connecting hole is completed at the same time, and the action can be fully automated without manual intervention, which can greatly improve production efficiency.

[0006] As an improvement of the present invention, a movable groove for the ejection and retraction block to move is provided on one side of the straight ejector head close to the reinforcing rib. When the straight ejector head and the ejection and retraction block form the reinforcing rib, a gap is provided between the ejection and retraction block and the bottom of the movable groove. Through the improvement, the relative stability of the ejection and retraction block relative to the movement of the straight ejector head can be ensured by the design of the movable groove, and the design of the gap can prevent the ejection and retraction block from moving synchronously with the straight ejector head when the straight ejector head ejects the product without eliminating the gap, thereby realizing the separation of the rib-forming groove and eliminating the movement interference between the ejection and retraction block and the reinforcing rib.

[0007] As an improvement of the present invention, one end of the ejection retraction block close to the bottom of the movable groove is fixedly connected to a limiting screw, one end of the limiting screw is inserted from the end of the straight head away from the reinforcing rib into the movable groove and is fixedly connected to the ejection retraction block, a retraction spring is provided between the other end of the limiting screw and the end of the straight head away from the reinforcing rib, the retraction spring is in a compressed state, and a protrusion protruding from the movable groove is provided on the side of the ejection retraction block. In the case of mold closing, the protrusion is used to limit the movement of the ejection retraction block in the direction away from the reinforcing rib. Through the improvement, The limit screw further ensures the stability of the movement between the ejector retraction block and the straight ejector head, and also prevents the ejector retraction block from escaping from the moving groove. The retraction spring ensures that the ejector retraction block will not move synchronously when the straight ejector head is ejecting. The limit design of the protrusion prevents the ejector retraction block from moving toward the bottom of the moving groove to eliminate the gap under the action of the retraction spring in the mold closing state, thereby ensuring the gap between the ejector retraction block and the bottom of the moving groove, and at the same time ensuring the stability of the ejector retraction block and the straight ejector head when the gap is not eliminated.

[0008] As an improvement of the present invention, the straight top head is fixedly connected to a straight top seat, the stripping assembly is also fixedly connected to the straight top seat, the forming rod is provided with a rotating thread and a rotating gear, the forming rod is threadedly connected to the straight top seat through the rotating thread, when the forming rod rotates, the forming rod will move synchronously along the axial direction of the forming rod due to the threaded transmission connection, the rotating gear rotates during the demolding process to drive the forming rod to rotate synchronously, through the improvement, the purpose of demolding the connecting buckle can be achieved by rotating the forming rod through the design of the rotating thread and the rotating gear.

[0009] As an improvement of the present invention, the stripping assembly also includes a gear chain connected to the rotating gear for sprocket transmission. One end of the gear chain is fixedly connected to a chain seat, and the other end of the gear chain is connected to the chain seat through a tension spring after passing around the rotating gear. During the demolding process, the chain seat is in a relatively static state. Through the improvement, when demolding, the straight ejector is ejected through the straight ejector seat, thereby synchronously driving the stripping assembly to move. At this time, the tension spring will be stretched, so that the gear chain will undergo gear transmission on the chain seat, thereby causing the forming rod to rotate, and then the axial movement of the forming rod is realized through the threaded transmission connection of the rotating thread to complete the demolding of the connecting hole.

[0010] As an improvement of the present invention, the straight ejector seat is fixedly connected to a straight ejector slide seat via a straight ejector rod, and the straight ejector slide seat is fixedly connected to the ejector plate. Through the improvement, the driving connection of the ejector plate to the straight ejector seat is realized.

[0011] As an improvement of the present invention, the straight ejector rod passes through the chain seat, and when the straight ejector rod moves axially parallel to the forming rod, the chain seat is driven to move synchronously. Through the improvement, when the straight ejector rod moves perpendicular to the ejection direction, the chain seat can be driven to move synchronously perpendicular to the ejection direction, which helps to better demold the connecting hole.

[0012] As an improvement of the present invention, an inclined guide column with an inclined design is provided on the side of the straight top slide away from the reinforcing rib, and an inclined hole arranged parallel to the inclined guide column is provided on the straight top slide. The inclined guide column is movably connected in the inclined hole, and a moving gap is provided between the inclined hole and the inclined guide column. During the demolding process, the straight top slide first moves along the demolding direction, and after the moving gap is eliminated, the straight top slide moves along the direction of the inclined guide column. Through the improvement, a multi-stage demolding process can be formed during the demolding process. At the beginning of demolding, the straight top slide first moves along the ejection direction. At this time, the reinforcing rib is demolded and the connecting hole is preliminarily demolded. Then, when the straight top slide moves along the direction of the inclined guide column, the molding rod and the connecting hole can be fully demolded, thereby ensuring that the product can be taken out of the mold cavity smoothly.

[0013] As an improvement of the present invention, the straight top slide is provided with a multi-section limit seat on one side of the inclined direction of the inclined hole, and the multi-section limit seat includes a straight portion for ensuring that the straight top slide moves along the demolding direction and an inclined portion for ensuring the stability of the straight top slide in the inclined movement along the inclined guide column. Through the improvement, because there is no strong connection structure between the straight top slide and the inclined guide column, the inclined guide column is not sufficient to serve as a movement limit for the straight top slide, and the movement of the straight top slide is not stable in a direction perpendicular to the ejection direction, thereby adding a multi-section limit seat design, when the straight top slide moves in the ejection direction, it only moves in the ejection direction, and when it moves in the direction of the inclined guide column, it can move in the direction of the inclined guide column.

[0014] As an improvement of the present invention, one end of the straight-top slide close to the multi-section limit seat includes a contact plane and a contact bevel, one end of the straight surface portion is connected to the demolding bevel portion, and the end of the straight surface portion away from the demolding bevel portion is provided with a closing bevel portion, and the closing bevel portion and the demolding bevel portion have the same slope. In the closing state, the contact bevel and the closing bevel portion are contacted, and in the demolding state, the contact plane first contacted the straight surface portion, and after eliminating the moving gap, the contact plane and the straight surface portion are separated, and the contact bevel and the demolding bevel portion are contacted. Through the improvement, through the design of the closing bevel portion, the straight-top slide in the closing state can be limited, thereby ensuring the state of the straight-top slide in the closing state, and then ensuring the movement accuracy and stability of the straight-top slide during the demolding process.

The rotating gear 5.2 rotates during the demoulding process to drive the forming rod 5.1 to rotate synchronously. The hole-removing component 5 also includes a gear chain 5.3 connected to the rotating gear 5.2 by sprocket transmission. One end of the gear chain 5.3 is fixedly connected to a chain seat 5.4. The other end of the gear chain 5.3 passes around the rotating gear 5.2 and is then connected to the chain seat 5.4 through a tension spring 5.5. During the demoulding process, the chain seat 5.4 is in a relatively static state.

[0030] like Figure 1 , Figure 2 , Figure 8 , Fig. 9As shown, the straight ejector seat 8 is fixedly connected to a straight ejector slide 9 through a straight ejector rod 10, and the straight ejector slide 9 is fixedly connected to an ejector pin plate 14. The ejector pin plate 14 includes two fixedly connected clamping plates. A limit moving bar 9.5 is provided on the side of the straight ejector slide 9, and a limit moving groove 1.1 for the limit moving bar 9.5 to be movably connected is provided between the two clamping plates. When the ejector pin plate 14 moves up and down, it can drive the straight ejector slide 9 to move up and down synchronously, but the limit moving bar 9.5 can also move left and right in the limit moving groove 1.1. The straight ejector rod 10 passes through the chain seat 5.4, and when the straight ejector rod 10 moves axially parallel to the forming rod 5.1, it drives the chain seat 5.4 to move synchronously. An inclined guide column 11 with an inclined design is provided on the side of the straight top slide 9 away from the reinforcing rib 3.1. An inclined hole 9.1 arranged parallel to the inclined guide column 11 is provided on the straight top slide 9. The inclined guide column 11 is movably connected in the inclined hole 9.1. A moving gap 9.2 is provided between the inclined hole 9.1 and the inclined guide column 11. During the demolding process, the straight top slide 9 first moves along the demolding direction. After the moving gap 9.2 is eliminated, the straight top slide 9 moves along the direction of the inclined guide column 11.

[0031] like Figure 2 , Fig. 9 As shown, the straight top slide 9 is provided with a multi-stage limit seat 12 on one side of the inclined direction of the inclined hole 9.1, and the multi-stage limit seat 12 includes a straight surface portion 12.1 for ensuring that the straight top slide 9 moves along the demoulding direction and a demoulding inclined surface portion 12.2 for ensuring the stability of the straight top slide 9 when the straight top slide 9 moves along the inclined guide column 11.

[0032] The chain seat 5.4 is movably connected to the front template 13. A moving cavity for the chain seat 5.4 to move is provided at the lower end of the front template 13. The inclined guide pillar 11 and the multi-stage limit seat 12 are fixedly connected to the hot runner plate 15.

[0033] During the demoulding process, the steps are as follows:

[0034] S1: the ejector plate 14 moves a short distance L1 toward the straight ejector head 1, where L1 is slightly greater than the thickness of the reinforcing rib 3.1;

[0035] S2: the straight push slide 9 moves along the straight surface portion 12.1 toward the straight push head 1 by a distance L1, and the straight push head 1 accordingly pushes the product 3 out of the front template 13 by a distance L1;

[0036] S3: The ejector retraction block 2 remains stationary under the action of the retraction spring 7, the gap 1.2 is eliminated, the ejector retraction block 2 is lower than the straight ejector head 1, the rib groove 4 is separated, and the movement interference between the ejector retraction block 2 and the reinforcing rib 3.1 is eliminated; at the same time, the rotating gear 5.2 moves toward the straight ejector head 1 by a distance L1, and the tension spring 5.5 is extended by a distance of 2*L1, so that the gear chain 5.3 drives the rotating gear 5.2 to rotate;

[0037] S4: The rotating gear 5.2 drives the forming rod 5.1 to rotate. Under the threaded transmission connection of the rotating thread 5.1.1, the forming rod 5.1 moves to remove the hole. The moving distance of the removal is D1.

[0038] S5: the ejector plate 14 continues to move toward the straight ejector head 1 by a distance L2, where the distance L2 is greater than the distance L1;

[0039] S6: the straight ejector slide 9 moves along the straight surface portion 12.1 toward the straight ejector head 1 by a distance L2, and the corresponding straight ejector head 1 continues to eject the product 3 away from the front template 13 by a distance L2, and eliminates the moving gap 9.2, and the side of the inclined hole 9.1 away from the straight ejector head 1 abuts against the inclined guide column 11;

[0040] S7: The ejector retracting block 2 is ejected synchronously by a distance L2; at the same time, the rotating gear 5.2 moves toward the straight ejector head 1 by a distance L2, and the tension spring 5.5 is extended by a distance of 2*L2, so that the gear chain 5.3 drives the rotating gear 5.2 to rotate;

[0041] S8: The rotating gear 5.2 drives the forming rod 5.1 to rotate. Under the threaded transmission connection of the rotating thread 5.1.1, the forming rod 5.1 moves out of the hole. The moving distance of the moving out of the hole is D2, so that the forming rod 5.1 is separated from the connecting hole 3.2;

[0042] S9: The ejector plate 14 moves toward the straight ejector head 1 by a distance L3;

[0043] S10: the straight ejector slide 9 moves along the inclined guide column 11 toward the straight ejector head 1 by a distance L3, and moves toward the multi-stage limit seat 12 by a distance D3. Accordingly, the straight ejector head 1 continues to eject the product 3 away from the front template 13 by a distance L3, and the straight ejector seat 8 moves axially along the forming rod 5.1 away from the connecting hole 3.2 by a distance D3;

[0044] S11: The ejector retracting block 2 is ejected synchronously by a distance L3 and crosses the reinforcing rib 3.1; at the same time, the rotating gear 5.2 moves a distance L3 toward the straight ejector head 1, and the tension spring 5.5 is extended by a distance 2*L3, so that the gear chain 5.3 drives the rotating gear 5.2 to rotate;

[0045] S12: The rotating gear 5.2 drives the forming rod 5.1 to rotate. Under the threaded transmission connection of the rotating thread 5.1.1, the forming rod 5.1 moves away from the connecting hole 3.2 by a moving distance of D4, ensuring that the forming rod 5.1 is fully separated from the connecting hole 3.2, so as to facilitate the removal of the product 3;

[0046] S13: Take out product 3.

[0047] In steps S4, S8, and S12, when the moving distances D1, D2, and D4 are reached, the forming rod 5.1 and the rotating gear 5.2 are connected in a circumferential limit manner through the connecting key, and the forming rod 5.1 and the rotating gear 5.2 undergo axial relative movement, but this does not affect the circumferential synchronous rotation connection between the two. During the demoulding process, the ejection distance of the straight ejector 1 is L1+L2+L3, which is the same as the moving distance of the ejector plate 14, while the hole removal distance of the forming rod 5.1 is D1+D2+D3+D4.

[0048] The reset step only requires moving the ejector plate 14 in the reverse direction. The straight ejector head 1, the ejection retraction block 2, the knockout assembly 5, and the straight ejector slide 9 can all return to the original path and reset. However, the tilting movement of the straight ejector slide 9 during the reset stroke no longer relies on the inclined guide column 11, but relies on the demoulding inclined surface 12.2.

[0049] During the demoulding process, only relying on the traditional ejector plate 14 ejector demoulding operation, the demoulding of the reinforcing rib 3.1 and the demoulding of the connecting hole 3.2 can be completed in a small space, and the demoulding quality is fully guaranteed, the design of manual inlay is reduced, and it can be fully put into automated production, thereby greatly improving the production efficiency of product 3.

[0050] In actual production, the mold structure can be applied to both single-color and multi-color molds, without worrying about the impact on the quality of product 3. And the mold structure is also suitable for small space demoulding of the connecting hook structure.

The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
