Description

Technical Field

[0001] The invention belongs to the technical field of molds and relates to a fast-opening and closing draw hook safety dryness reduction and resetting structure. Background Art

[0002] In hot runner equipment, the problem that needs to be solved is that during the production process, after the needle valve moves for a long time, there will be a lot of material powder on the manifold, which is difficult to clean. At present, before cleaning this type of equipment, it is necessary to pull the mold open through the mold opening structure. Most common turnover box molds use a cylinder open slider structure in terms of structural movement. This mechanism has a long cycle. Some customers pursue a short cycle and use a hook structure. This mechanism has a significant reduction in cycle, but in the common pull rod hook structure, because there is lateral friction in the direction of movement, the buffer parts have no service life under the support of friction. It is impossible to design a buffer spring, and it is impossible to achieve noise reduction. Therefore, it is urgent to design a quick opening and closing hook safety and noise reduction reset structure that can overcome the above defects.

[0003] In order to overcome the shortcomings of the prior art, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses a dashboard mold hook structure [application number: 201711226540.1], which includes an ejector plate, an ejector block is provided below the ejector plate, a connecting block is provided on the ejector plate, a pull rod is hingedly provided on the connecting block, a wear-resistant block is provided on the outer wall of the movable mold, a hook is provided at the end of the pull rod away from the connecting block, a receiving groove is provided on the upper surface of the hook, and the wear-resistant block is limited in the receiving groove. When the mold is opened, the movable mold moves downward to drive the pull rod to move downward together, thereby driving the ejector plate and the inclined ejector block to move downward to eject the product. However, during use, this solution still has lateral friction in the direction of movement. The buffer parts have no service life under the influence of friction. There are defects such as the inability to design buffer springs and the inability to achieve noise reduction. Summary of the invention

[0004] The object of the present invention is to provide a fast opening and closing hook safety and dryness reduction reset structure in view of the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A quick-opening and closing hook safety noise reduction and reset structure comprises a lower die and an upper die, wherein a mold alignment plate is provided between the lower die and the upper die, wherein a fixed block is provided on the mold alignment plate, wherein a through hole is provided in the fixed block, wherein a hook member is provided on the lower die which passes through the through hole and slidably cooperates with the upper die, wherein the hook member is fixedly connected to the lower die by a screw connection, wherein a rotatable flip cover body is provided on the fixed block, wherein the flip cover body can rotate along a side close to or away from the through hole, wherein a noise reduction and buffer structure is further provided on the fixed block, wherein the noise reduction and buffer structure corresponds to the position of the flip cover body, wherein a detachable reinforcement member is provided on the top of the flip cover body, wherein the detachable reinforcement member corresponds to the position of the hook member.

[0007] In the above-mentioned quick-opening and closing hook safety dryness reduction and reset structure, the hook member includes a hook slide bar and a hook protrusion, and the hook protrusion is arranged opposite to the detachable reinforcement member.

[0008] In the above-mentioned fast opening and closing hook safety dryness reduction and reset structure, a hook slide groove is provided in the upper mold, and the hook slide rod is slidably matched with the hook slide groove.

[0009] In the above-mentioned quick opening and closing hook safety dryness reduction and reset structure, the screw connection member includes a first fastening bolt arranged between the hook slide bar and the lower die, and the width of the hook protrusion is smaller than the width of the through hole.

[0010] In the above-mentioned quick opening and closing hook safety and dryness reduction reset structure, the flip cover body and the fixed block are connected by a self-resetting rotating connection structure. When the flip cover body is closed, a gap is formed between the flip cover body and the hook slide bar.

[0011] In the above-mentioned quick-opening and closing hook safety noise reduction and reset structure, the noise reduction and buffer structure includes two rubber springs arranged on a fixed block, the rubber springs are fixed to the fixed block by screws, and the rubber springs are arranged opposite to the flip cover body.

[0012] In the above-mentioned quick-opening and closing hook safety dryness reduction and reset structure, a placement groove is provided in the fixing block, the rubber spring is located in the placement groove and the top of the rubber spring extends out of the placement groove.

[0015] In the above-mentioned quick-opening and closing hook safety dryness reduction and reset structure, the fixing block and the mold alignment plate are fixed by a second fastening bolt.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. When the mold is opened, the present invention rotates the flip cover body away from the end of the hook piece to open the through hole, so that the hook piece can slide along the through hole. The hook structure is used instead of the cylinder slider structure, which can significantly shorten the molding cycle, achieve the purpose of rapid production, and improve production efficiency. When resetting is required, the flip cover body adopts a flip cover design, and the hook piece can push the flip cover open when it hits the resetting force of the flip cover body, and the hook piece completes the resetting. When closing the cover, the bottom of the flip cover body will contact the noise reduction buffer structure, which can effectively reduce noise through the noise reduction buffer structure. The detachable reinforcement part can strengthen the top of the flip cover body and increase the service life of the flip cover body.

[0050] The rubber spring 16 is fixed to the fixing block 4 by screws, and the disassembly and replacement are simple and convenient. When the cover is closed, the bottom of the flip cover body 8 will contact the rubber spring 16, and the noise reduction buffer structure 9 can effectively reduce noise. The placement groove 17 is used to install and fix the rubber spring 16. The top of the rubber spring 16 extends outside the placement groove 17, and there is sufficient space to contact the bottom of the flip cover body 8 to avoid collision between the bottom of the flip cover body 8 and the fixing block 4.

[0051] The flip cover body 8 and the fixed block 4 are rotated and self-reset through the rotating shaft 18 and the torsion spring 19, which can be easily rotated. When the flip cover body 8 is closed, a gap is formed between the flip cover body 8 and the hook slide bar 11 to avoid collision and interference. In addition, when the torsion spring 19 fails, the hook slide bar 11 and the hook protrusion 12 can be reset at any time. Therefore, the spring structure can be removed, saving processing costs, accessory costs and spring quality issues.

[0052] The reinforcement plate 20 is fixed to the flip cover body 8 by screws, and disassembly and assembly are simple and convenient. The reinforcement plate 20 is made of UPE material, which has high wear resistance and high impact resistance.
