Description

Technical Field

[0001] The invention relates to a secondary demoulding mold based on a Haver slider and a molding method thereof, belonging to the technical field of molds. Background Art

[0002] In the production process of plastic products, the design of the mold and the demoulding method play a vital role in product quality and production efficiency. Traditional mold demoulding methods often have some limitations. For example, for plastic products with complex structures, undercuts or special shapes, one demoulding is difficult to meet the complete release requirements of the product, which can easily cause product deformation and damage, affect the dimensional accuracy and surface quality of the product, and thus reduce the product qualification rate and increase production costs. For example, the Chinese utility model patent with the authorization announcement number CN215320372U discloses a front mold Haval slider active ejection mechanism injection mold, and specifically discloses a first front mold assembly, a second front mold assembly, a rear mold assembly, and a mold core located between the second front mold assembly and the rear mold assembly, which are arranged in sequence from front to back and can move relatively; the mold core includes a front mold core and a rear mold core, and a core is convexly provided on the rear mold core, and the front mold core includes at least two inclined sliders that can slide obliquely in the second front mold assembly; when the mold is closed, the inclined sliders jointly enclose to form an insertion cavity, and the core of the rear mold core is inserted into the insertion cavity, and together with the front mold core, it forms a cavity for injection molding products. During the demoulding process of the mold, elastic parts are used to assist the product to detach from the mold. However, when the demoulding action just begins, the elastic parts are in a state of high elastic potential energy, and the elastic force released is relatively large. Since the product is still in close contact with the mold in the initial stage of demoulding and its own structure is relatively fragile, excessive elastic force directly acts on the product, which can easily cause the product to be subjected to stress beyond its tolerance range, thereby causing damage to the product such as cracking and deformation, seriously affecting the quality and yield rate of the product.

[0010] The aforementioned secondary demoulding mold based on the Haval slider has a plurality of telescopic guide rods arranged between the front mold and the rear mold.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In the present invention, the front mold is connected to the external lifting mechanism through a connecting plate. When the mold is closed, the front mold is lowered by the external lifting mechanism so that the lower end surface of the front mold conflicts with the upper end surface of the rear mold. At this time, a molding cavity is formed between the Haver slider mechanism and the rear mold, and then the oil cylinder of the second demolding mechanism extends so that the slider passes through the first through groove into the molding cavity and matches the molding surface of the rear mold. After the feedback mechanism senses that the slider has moved into place, it issues an instruction to make the external injection molding machine pour molten plastic into the injection molding mechanism, and the molten plastic flows into the molding cavity through the injection molding mechanism to wait for molding; after the product is cooled and formed, the extended end of the oil cylinder retracts, so that a gap appears between the product and the rear mold, and the first demolding is realized. After the feedback mechanism senses that the slider is completely retracted and does not contact the Haver slider mechanism, the external lifting mechanism causes the front mold to rise and separate from the product, and then the second demolding is realized through the first demolding mechanism. As a result, the present invention realizes the effect of realizing the second demolding through the double demolding mechanism after the injection molding is completed with the help of the molding cavity, which has the advantages of improving production efficiency and ensuring product quality.

[0013] 2. In the present invention, after the front mold descends, the lower end surface of the shaping slider of the Haver slider mechanism will contact the upper end surface of the rear mold. As the front mold continues to descend, it gathers inward under the action of the inclined surface of the groove side wall and the inclined first guide rod, and finally forms a molding cavity with the rear mold. The first spring is used to reset the shaping slider when the front mold and the rear mold are separated, so that the shaping slider is dispersed outward to facilitate separation from the product.

[0014] 3. In the present invention, the ejection end of the external ejection mechanism passes through the third through slot and is connected to the movable plate. When demolding is required, the movable plate is driven to move upward by the ejection mechanism, so that the first ejection rod moves upward accordingly until its upper end surface contacts the second ejection rod, so that the second ejection rod passes through the second barrel slot to eject the product, so that the product is separated from the rear mold, wherein the second guide rod and the third guide rail are used to ensure the stability of the lifting and lowering of the movable plate, and the second spring is used to reset the movable plate after the ejection end of the external ejection mechanism descends.

[0015] 4. In the feedback mechanism of the present invention, when the slider is extended to the designated position in the molding cavity and fully retracted without contacting the Haver slider mechanism, the contact block will contact the roller, causing the L-shaped rod to bend inward and touch the contact point, sending a signal to facilitate the next operation of the device. The inclined portion is used to guide the roller to smoothly contact the contact block to reduce mechanical wear. BRIEF DESCRIPTION OF THE DRAWINGS

Four telescopic guide rods 16 are arranged between the front mold 3 and the rear mold 2, and the telescopic guide rods 16 are used to ensure the consistency of the docking of the front mold 3 and the rear mold 2.

[0026] Preferably, if Figure 6 and 7 As shown, the Haver slider mechanism 5 includes a groove 20 arranged below the front mold 3, and the side wall of the groove 20 is inclined; a plurality of first guide rods 21 are inclinedly arranged inside the groove 20, and the inclination angle of the first guide rod 21 is the same as that of the groove, and a shaping slider 22 is slidably connected below the first guide rod 21; a first spring 23 surrounds the outer side of the first guide rod 21; and the first through groove 14 is arranged on the shaping slider 22 near the side of the oil cylinder 11. After the front mold of the Haver slider mechanism 5 descends, the lower end surface of the shaping slider 2213 will contact the upper end surface of the rear mold 2. As the front mold 3 continues to descend, under the action of the inclined surface of the side wall of the groove 20 and the inclined first guide rod 21, it gathers toward the inside, and finally forms a molding cavity 6 with the rear mold 2. The first spring 23 is used to reset the shaping slider 22 when the front mold 3 and the rear mold 2 are separated, so that the shaping slider 22 is dispersed outward, which is convenient for separation from the product. Furthermore, a plurality of fifth guide rods are provided on both sides of the displacement shaping slider 22 in the groove 20 , and the fifth guide rods are slidably connected to the side of the shaping slider 22 , so as to further ensure the stability of the movement of the shaping slider 22 .

The connector 31 is connected to the liquid outlet of the external injection molding machine. After receiving the injection molding instruction, the external injection molding machine pours molten plastic into the injection molding mechanism 7, and the molten plastic flows into the molding cavity 6 after passing through the first injection molding tube 30 and the second injection molding tube 32 to wait for molding.

[0028] Preferably, if Figure 2 As shown, the first demoulding mechanism 8 includes a moving cavity 40 arranged on the base 1, and a moving plate 41 is arranged in the moving cavity 40; the rear mold 2 is provided with a plurality of second through slots 42 connected to the molding cavity 6, and a second ejector rod 48 is slidably connected to the upper end of the second through slot 42, and the upper end surface of the second ejector rod 48 is matched with the upper end surface of the rear mold 2; the moving plate 41 is provided with a plurality of first ejector rods 43, and the first ejector rods 43 are slidably connected to the second through slots 42; and a plurality of third through slots 44 are arranged below the base 1. A plurality of second guide rods 45 are arranged between the bottom of the moving cavity 40 and the bottom of the rear mold 2, and the second guide rods 45 are slidably connected to the moving plate 41; the fourth corners of the bottom of the moving cavity 40 and the bottom of the rear mold 2 are respectively provided with third guide rods 46, and the third guide rods 46 are slidably connected to the moving plate 41; the outer side of the third guide rod 46 is surrounded by a second spring 47. The ejection end of the external ejection mechanism passes through the third through slot 44 and is connected to the movable plate 41. When demoulding is required, the movable plate 41 is driven upward by the ejection mechanism, so that the first ejection rod 43 moves upward accordingly until its upper end surface contacts the second ejection rod 48, so that the second ejection rod 48 passes through the second barrel slot to eject the product, so that the product is separated from the rear mold 2, wherein the second guide rod 45 and the third guide rail are used to ensure the stability of the lifting and lowering of the movable plate 41, and the second spring 47 is used to reset the movable plate 41 after the ejection end of the external ejection mechanism descends.

[0029] Preferably, if Figure 4 and 5As shown, the feedback mechanism 15 includes an electronic induction switch 50 symmetrically arranged on the oil cylinder seat 10, and an L-shaped rod 51 is arranged on the side of the electronic induction switch 50. The L-shaped rod 51 is made of high-strength plastic material, light in weight and has a certain elasticity. A roller 52 is arranged at the other end of the L-shaped rod 51; a contact 53 corresponding to the roller 52 is arranged on the side of the electronic induction switch 50; the feedback mechanism 15 also includes a contact block 54 arranged on the side of the slider seat 12, and an inclined portion 55 is arranged on both sides of the contact block 54. When the slider 13 extends into the specified position in the molding cavity 6 and is completely retracted and does not contact the Haver slider mechanism 5, the contact block 54 will conflict with the roller 52, so that the L-shaped rod 51 bends inward and touches the contact 53, sending a signal, so that the equipment can proceed to the next operation. The inclined portion is used to guide the roller 52 to smoothly contact the contact block 54 to reduce mechanical wear.

[0030] The molding method of the secondary demoulding mold based on the Haval slider has the following steps:

[0031] Mold closing: The front mold 3 is connected to the external lifting mechanism through the connecting plate 4. When the mold is closed, the front mold 3 is lowered through the external lifting mechanism so that the lower end surface of the front mold 3 is in conflict with the upper end surface of the rear mold 2. At this time, a molding cavity 6 is formed between the Haver slider mechanism 5 and the rear mold 2, and then the cylinder 11 of the second demolding mechanism 9 is extended, so that the slider 13 passes through the first through groove 14 and enters the molding cavity 6 to match the molding surface of the rear mold 2, completing the mold closing.

[0032] Injection molding: When the slider 13 penetrates into the molding cavity 6 and fits with the molding surface of the rear mold 2, the contact block 54 on the side of the slider seat 12 will conflict with the roller 52 on the corresponding electronic sensor switch 50, so that the L-shaped rod 51 is completely in contact with the contact 53, so that the electronic sensor switch 50 sends a command to the external injection molding machine, and the injection molding machine pours molten plastic into the injection molding mechanism 7. The molten plastic flows into the molding cavity 6 through the injection molding mechanism 7 and waits for molding.

[0033] Demolding: After the product is cooled and formed, the extended end of the cylinder 11 begins to retract. As the cylinder 11 retracts, the slider seat 12 connected to it drives the slider 13 to gradually leave the molding cavity 6 and separate from the Haver slider mechanism 5. During this process, as the slider 13 separates from the product, the product and the Haver slider mechanism become loose, making it easy to separate later. When the slider 13 is fully retracted and no longer in contact with the Haver slider mechanism 5, the contact block 54 on the side of the slider seat 12 will conflict with the roller 52 on the corresponding electronic sensor switch 50, so that the L-shaped rod 51 is completely in contact with the contact 53. The electronic sensor switch 50 sends a command to the external lifting mechanism, and the external lifting mechanism drives the front mold 3 to rise. At this time, the Haver slider mechanism 5 begins to change state under the action of the first spring 23. When the front mold 3 is lowered to close the mold, the shaping sliders 22 gather inward to form the molding cavity 6 under the action of the side wall slope of the groove 20 and the inclined first guide rod 21. When the front mold 3 rises, the first spring 23 releases its elastic force, pushing the shaping sliders 22 to disperse outward along the first guide rod 21. During the process of the shaping sliders 22 dispersing outward, the contact between them and the product is gradually reduced, and the binding force on the product is also reduced, thereby achieving the first demolding.

[0034] Subsequently, the first demoulding mechanism 8 is started, and the ejection end of the external ejection mechanism passes through the third through slot 44 and is connected to the movable plate 41, driving the movable plate 41 to move upward. The first ejection rod 43 on the movable plate 41 moves upward accordingly, and when the upper end surface of the first ejection rod 43 contacts the second ejection rod 48, the continued upward thrust causes the second ejection rod 48 to pass through the second through slot 42, ejecting the product from the rear mold 2, and realizing secondary demoulding. In this process, the second guide rod 45 and the third guide rod 46 play a guiding role, ensuring that the movable plate 41 is lifted and lowered smoothly, and the second spring 47 resets the movable plate 41 after the ejection end of the external ejection mechanism drops, preparing for the next demoulding operation.
