Description

Technical Field

[0001] This utility model belongs to the field of membrane separation technology, and in particular relates to a demolding device for tubular fiberglass products. Background Technology

[0002] Currently, in the field of membrane separation technology, demolding equipment for membrane shell products typically uses ring sleeves for assisted demolding. These ring sleeves need to be manually fitted onto the mold before demolding. Because membrane shell product molds are relatively long, they require lifting from both ends for transfer, making the process of fitting the complete ring-shaped device onto the mold cumbersome. Non-ring-shaped clamping fixtures, on the other hand, can easily damage fiberglass products. Therefore, this paper designs a demolding device for fiberglass tubular products that is adaptable to fiberglass products, ensuring reliable demolding and optimizing the operation process.

[0003] In view of this, the present invention aims to propose a demolding device for tubular fiberglass products, so as to solve the problem that the demolding equipment assembly process for membrane shell products in the existing membrane separation technology is cumbersome and easily causes damage to fiberglass products.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a demolding device for tubular fiberglass products, comprising a base plate, a pressure plate, and several clamping structures. The pressure plate is disposed on the lower half of one side of the base plate. The base plate is evenly provided with several U-shaped grooves corresponding to the clamping structures. Each clamping structure includes an upper clamping sleeve and a lower clamping sleeve, both disposed on one side of the base plate. The lower clamping sleeve is disposed on the lower half of the U-shaped groove and is movably disposed in the cavity between the base plate and the pressure plate. The upper clamping sleeve is rotatably disposed on the upper half of the U-shaped groove and mates with the lower clamping sleeve. The bottom ends of the upper clamping sleeve are connected to the top ends of the lower clamping sleeve, and one end of the upper clamping sleeve is rotatably connected to the base plate.

[0005] Furthermore, a circular hole is formed between the upper and lower sleeves.

[0006] Furthermore, a buffer mechanism is provided at the bottom of the lower sleeve, and the buffer mechanism (5) is located in the cavity between the base plate and the pressure plate.

[0007] Furthermore, the buffer mechanism is a hydraulic buffer, and the top of the hydraulic buffer is connected to the lower sleeve.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0027] See Figure 1-9This embodiment describes a demolding device for tubular fiberglass products, comprising a base plate 1, a pressure plate 2, and several clamping structures. The pressure plate 2 is disposed on the lower half of one side of the base plate 1. The base plate 1 has several U-shaped grooves evenly distributed, each corresponding to one of the clamping structures. Each clamping structure includes an upper clamping sleeve 4 and a lower clamping sleeve 3, both disposed on one side of the base plate 1. The lower clamping sleeve 3 is disposed on the lower half of the U-shaped groove and is movably disposed in the cavity between the base plate 1 and the pressure plate 2. The upper clamping sleeve 4, which rotatably cooperates with the lower clamping sleeve 3, is rotatably disposed on the upper half of the U-shaped groove. The bottom ends of the upper clamping sleeve 4 are connected to the top ends of the lower clamping sleeve 3, and one end of the upper clamping sleeve 4 is rotatably connected to the base plate 1. The locking mechanism of the membrane housing is achieved by the matching upper sleeve 4 and lower sleeve 3. The matching upper sleeve 4 and lower sleeve 3 are set as the locking structure. The mold 11 only needs to be placed on the lower sleeve 3 and the upper sleeve 4 can be closed to complete the installation of the demolding device. The installation process is simple and easy to operate, which effectively improves the demolding efficiency.

[0028] The number and position of the ferrule structure can be adjusted according to the actual needs of the mold 11. In this embodiment, there are two ferrule structures, which are symmetrically arranged on the base plate 1.

[0029] In this embodiment, a circular hole is formed between the upper sleeve 4 and the lower sleeve 3.

[0030] The bottom of the lower sleeve 3 is provided with a buffer mechanism 5, which is located in the cavity between the base plate 1 and the pressure plate 2. In this embodiment, the buffer mechanism 5 is a hydraulic buffer, which is located in the cavity of the pressure plate 2. In this embodiment, the internal cross brace of the pressure plate 2 has a threaded hole, and a hydraulic buffer is installed on the threaded hole. The top of the hydraulic buffer is connected to the lower sleeve 3, which can offset the weight of the lower sleeve 3 and provide a buffering effect when the mold 11 presses down on the lower sleeve 3, ensuring the initial position fits the mold 11 and has the ability to adjust up and down.

[0031] In this embodiment, one end of the upper sleeve 4 is provided with a slot 6, and the slot 6 is movably connected to the base plate 1 by bolts, such as... Figure 6 As shown, the slot 6 is elongated and its position can float up and down or left and right within the allowable gap range. It can automatically float and adjust according to changes in working conditions and the mold.

[0032] In this embodiment, both the upper sleeve 4 and the lower sleeve 3 have the ability to be adjusted up and down, realizing the self-centering function of the device, ensuring the coaxiality of the fixture and the mold 11, and can perfectly replace the traditional ring tooling, providing a basic guarantee for the automated control of the equipment and reducing the defect rate of the demolding process.

[0033] In this embodiment, the lower sleeve 3 has ear plates 7 at both ends of its top, and the ear plates 7 have first pin holes 8. The upper sleeve 4 has second pin holes 9 at both ends of its bottom, which are corresponding to the first pin holes 8. The first pin holes 8 and the second pin holes 9 are connected by a shaft pin. After the first pin holes 8 and the second pin holes 9 are locked and fixed by the shaft pin, demolding begins.

[0034] In this embodiment, the base plate 1 and the pressure plate 2 are fixed together by bolts.

[0035] The operation steps in this embodiment are as follows:

[0036] Step 1: Unfolded state: The upper sleeve 4 is rotated around the bolt to open, and the lower sleeve 3 is supported at the initial height by the hydraulic buffer;

[0037] Step 2: Place the mold: Place the tubular fiberglass mold 11 horizontally in the arc-shaped groove of the lower sleeve 3;

[0038] Step 3: Close the sleeve: Rotate the upper sleeve 4 to the horizontal position, and its bottom locks with the top of the lower sleeve 3 through the shaft pin to form a complete circular hole, which holds the mold 11 tightly.

[0039] Step 4: Begin demolding.

[0040] The demolding methods described in this embodiment are divided into demolding shell form and demolding mold form.

[0041] In this embodiment, the demolding device is applied to demolding processes involving shell demolding, such as... Figure 8 As shown, the demolding device is fixed on the demolding trolley 13 and is driven to move by the demolding machine 10. The position of the mold 11 is fixed. The demolding device moves under the action of the demolding machine 10 and performs demolding operation on the film shell 12.

[0042] The demolding device described in this embodiment is applied to a demolding process such as a mold release device. Figure 9 As shown, one end of the mold 11 is fixed to the demolding carriage 13, and the demolding carriage 13 is driven to move by the demolding machine 10. The demolding device is fixed to the tail end of the demolding machine. The mold 11 moves under the action of the demolding machine 10. During the movement of the mold 11, the demolding device fixed to one end of the demolding machine performs demolding operation on the film shell 12.
