Description

Technical Field

[0001] This utility model relates to the field of bottle preform production, specifically to a mold-assisted demolding device for bottle preform production. Background Technology

[0002] PET plastic is lightweight, highly transparent, impact-resistant, and not easily broken. It can also block carbon dioxide gas. Due to its light weight, good shelf life, and the technological trend emphasizing heat resistance and pressure resistance, PET bottles have become the mainstream packaging material for beverages today. Many beverages that require high-temperature sterilization before filling, such as flavored water, juice, dairy products, and sports drinks, have also started using PET bottles for packaging. PET bottles have become the primary packaging material for beverage products. Because of its low environmental pollution and energy consumption, PET bottles are gradually replacing traditional packaging materials in today's increasingly environmentally conscious world. With its heat resistance and pressure resistance, it is replacing various PVC bottles, bags, aluminum cans, iron cans, and glass bottles, becoming the packaging material with the greatest growth potential. In the manufacturing process of plastic bottles, a preform is first injection molded using an injection molding machine, and then the preform is transferred to a blow molding line for blow molding.

[0003] However, in the current technology, the demolding of PET bottle preforms is mostly done manually with the help of auxiliary equipment, which increases the workload of workers and has low efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary demolding device for bottle preform production, which solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mold-assisted demolding device for bottle preform production, comprising a base, an injection nozzle at the center of the base, a lifting assembly, and a fixing sleeve; the fixing sleeve is installed on the base via the lifting assembly, and a fixing assembly for limiting the position of the bottle preform is installed inside the fixing sleeve;

[0006] The fixing component includes a clamping plate. The inner wall of the fixing sleeve is provided with several pairs of sliding grooves. A bidirectional threaded rod is rotatably installed in each pair of sliding grooves. A pair of threaded blocks are screwed onto each pair of threaded rods. A pair of connecting rods are hinged onto each pair of threaded blocks. The clamping plate is hinged to the other end of each pair of connecting rods.

[0007] Preferably, the lifting assembly includes a pair of toothed plates, which are fixedly installed at the bottom of the fixed sleeve. A pair of fixed columns are fixedly installed on the base, and each of the fixed columns has a cavity. The toothed plates are movably installed in the cavities.

[0008] Preferably, a gear that meshes with the toothed plate is rotatably mounted inside the cavity, and a second motor for driving the gear to rotate is fixedly mounted on the fixed column.

[0009] Preferably, the base has a concave mold.

[0010] Preferably, a first motor for driving the bidirectional threaded rod to rotate is fixedly installed on the fixed sleeve.

[0011] Beneficial effects

[0012] This utility model provides an auxiliary demolding device for preform production molds, which has the following advantages:

[0013] The preform can be placed on the base. A fixing sleeve is provided, and a fixing component can be installed inside the fixing sleeve. A double-threaded rod can be installed in the sliding groove. The rotation of the double-threaded rod can drive the threaded block to move, thereby causing the connecting rod to swing. The position of the clamping plate can be adjusted to clamp and fix the preform. The clamping plate is an arc-shaped plate. By setting the clamping plate as an arc-shaped plate, it can fit more closely with the preform, thus clamping the preform more stably. A lifting component is provided. Activating the lifting component can drive the fixing sleeve to rise, thereby lifting the preform and allowing the preform to detach from the base. No manual demolding is required, which greatly improves work efficiency. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Wherein, directional terms such as "upper" and "lower" mentioned herein are used in conjunction with... Figure 1 The orientation is used as a reference.

[0017] Please see Figure 1 This utility model provides a technical solution: a mold-assisted demolding device for bottle preform production, including a base 1, an injection nozzle 13 at the center of the base 1, a lifting component and a fixing sleeve 2; the fixing sleeve 2 is installed on the base 1 through the lifting component, and a fixing component for limiting the bottle preform is installed inside the fixing sleeve 2.

[0018] The fixing component includes a clamping plate 7. The inner wall of the fixing sleeve 2 is provided with several pairs of sliding grooves 3. A bidirectional threaded rod 4 is rotatably installed in each pair of sliding grooves 3. A pair of threaded blocks 5 are screwed onto each pair of threaded rods 4. A pair of connecting rods 6 are hinged onto each pair of threaded blocks 5. The clamping plate 7 is hinged to the other end of each pair of connecting rods 6.

[0019] The preform can be placed on the base 1. A fixing sleeve 2 is provided, in which a fixing component can be installed. A double-threaded rod 4 can be installed in the slide groove 3. The rotation of the double-threaded rod 4 can drive the threaded block 5 to move, thereby causing the connecting rod 6 to swing and adjust the position of the clamping plate 7 to clamp and fix the preform. The clamping plate 7 is an arc-shaped plate, which makes the arc-shaped plate fit the preform better, thus clamping the preform more stably. A lifting component is provided, which can be activated to lift the fixing sleeve 2, thereby lifting the preform and allowing it to detach from the base 1. No manual demolding is required, which greatly improves work efficiency.

[0020] Furthermore, the lifting assembly includes a pair of toothed plates 11, which are fixedly installed at the bottom of the fixed sleeve 2. A pair of fixed columns 9 are fixedly installed on the base 1, and each of the fixed columns 9 has a cavity 14. The toothed plates 11 are movably installed in the cavity 14.

[0021] By installing a pair of fixed posts 9, the fixed sleeve 2 can be placed on the pair of fixed posts 9. By opening a cavity 14, the toothed plate 11 can be raised and lowered within the cavity 14 to facilitate adjustment of the position of the fixed sleeve 2.

[0022] Furthermore, a gear 10 that meshes with the toothed plate 11 is rotatably installed inside the cavity 14, and a second motor for driving the gear 10 to rotate is fixedly installed on the fixed column 9.

[0023] The second motor is installed and started. The rotation of the second motor drive end can drive the gear 10 to rotate. The gear 10 meshes with the gear plate 11, which can drive the gear plate 11 to rise and fall.

[0024] Furthermore, a concave mold 12 is provided on the base 1, which can be used to place the preform into the concave mold 12.

[0025] Furthermore, a first motor 8 for driving the bidirectional threaded rod 4 to rotate is fixedly mounted on the fixed sleeve 2.

[0027] The working principle and usage process of this utility model are as follows: When in use, the bottle preform is placed on the base 1 and aligned with the cavity mold 12. The first motor 8 is started to drive the bidirectional threaded rod 4 to rotate, thereby driving a pair of threaded blocks 5 to move and drive the connecting rod 6 to swing, which in turn drives the clamping plate 7 to move until the bottle preform is clamped and fixed. The second motor is started to drive a pair of gears 10 to rotate, and the two gears 10 rotate in opposite directions. The two gears 10 simultaneously mesh with the teeth on the two toothed plates 11, jointly driving the toothed plates 11 to rise, thereby driving the fixing sleeve 2 and the bottle preform to rise, so as to demold.
