Description

Technical Field

[0001] The utility model belongs to production equipment and relates to a mold demoulding mechanism, and in particular to a bottom demoulding mechanism of a container mold. Background Art

[0002] A container is a structure that is used to hold materials and is mainly composed of a shell. Containers are usually produced using molds. For example, a wine jar mold is an industrial equipment used to make wine jars. The wine jar mold can produce wine jars of different shapes and sizes according to different needs. The wine jar mold can quickly and accurately replicate the shape and size of the wine jar, etc., to improve production efficiency. After the wine jar blank is formed in the mold, the formed wine jar needs to be removed from the mold.

[0003] When using the attached Figure 1 When the wine jar mold shown is used to produce wine jars, Figure 1 The wine jar mold shown is composed of a top mold, a middle mold and a bottom mold. The middle mold and the bottom mold of the wine jar mold are locked by means of claws, and the claws are arranged on the middle mold so that the claws can automatically pop open and release the connection between the middle mold and the bottom mold. The claws are connected to the middle mold by means of elastic components such as torsion springs to improve the convenience of use. At the same time, in order to prevent the claws from popping open at will, a limiting ring is used to cover the outside of the claws so that the claws are firmly locked to the bottom mold. The limiting ring slides up and down along the middle mold so that the claws can be pushed to release without restriction.

[0004] After the production of wine jars, the demoulding of the bottom mold is usually done manually. Due to the large size of the mold, manual demoulding is time-consuming and labor-intensive, and there are operational risks. Therefore, by using a dedicated mechanism to demould the bottom mold, the demoulding efficiency and safety can be improved. Utility Model Content

[0005] The utility model aims to solve the technical problem that manual bottom mold removal is time-consuming, labor-intensive and has operation risks, and provides a bottom mold removal mechanism for a container mold. The wine jar mold is supported by a tray, and the limiting ring on the middle mold is moved by the claws and the support to disengage the claws from the bottom mold, so that the bottom mold is unlocked, so that the bottom mold can be demoulded. The operation is simple, stable and efficient.

[0006] The technical solution adopted by the utility model is: to provide a bottom mold stripping mechanism for a container mold, comprising a machine base, a tray is arranged on the machine base for lifting, an assembly ring is coaxially arranged above the tray, and the assembly ring is installed and lifted with the machine base; a support is detachably installed on the bottom of the inner ring wall of the assembly ring along the circumferential direction, and a pusher claw is hinged on the top of the outer ring wall of the assembly ring for rotation along the circumferential direction.

[0007] The machine base supports the pallet. When demolding the bottom mold, after the wine jar mold is transferred to the pallet, the assembly ring moves up along the circumference of the wine jar mold to make the inside of the assembly ring abut against the bottom end of the limiting ring of the wine jar mold, and the position of the claw is rotated to adjust so that it abuts against the top of the limiting ring to clamp the limiting ring. After the assembly ring drives the limiting ring to move upward, the claws on the middle mold of the wine jar lose their restriction and pop open, thereby disconnecting the middle mold and the bottom mold, so that the bottom mold can be removed and the bottom mold demolding is completed. The operation is simple and the demolding can be continuous, which is efficient and safe.

[0008] To further optimize the technical solution, the pallet is installed by lifting and lowering the pallet with the help of a supporting cylinder and the machine base, the cylinder base of the supporting cylinder is fixedly installed with the machine base, the output end of the supporting cylinder is coaxially assembled with the pallet, and the pallet is installed by lifting and lowering the pallet with the help of a guide assembly and the machine base.

[0009] The supporting cylinder supports the pallet and adjusts the position of the pallet. It is stable and reliable to use and has low cost. When the pallet is lifted or moved, the guide assembly constrains its lifting movement, making its lifting movement stable and improving reliability.

[0010] To further optimize the technical solution, the guide assembly includes support rods that are evenly fixedly installed along the circumference at the bottom end of the tray, and the support rods are all slidably connected to the machine base.

[0011] The support rods at the bottom of the tray all pass through the machine base and are slidably connected to the machine base. The multi-position distribution of the support rods prevents the tray from rotating, making it stable and reliable to move up and down along the machine base.

[0012] To further optimize the technical solution, a lifting drive member is fixedly installed on the top of the base along the circumferential direction, and the output ends of the lifting drive member are assembled with the assembly ring.

[0013] The lifting drive member drives the assembly ring to move up and down. The lifting drive member is circumferentially distributed on the machine base. The assembly ring is supported at multiple positions, so that the assembly ring can be used reliably. The lifting drive member supports the assembly ring at multiple positions, so that its lifting operation is stable.

[0014] To further optimize the technical solution, a bracket is fixedly installed on the outer ring wall of the assembly ring along the circumferential direction, the bracket is rotatably hinged with the pusher claw, the bracket is drivingly connected to the pusher claw by means of a driving member, and an adjusting member is provided on the pusher claw.

[0015] The pusher claw is installed with the help of a bracket and an assembly ring, which does not interfere with the integrity of the assembly ring and avoids interference with the use of the assembly ring. The driving member drives the pusher claw to rotate to actively abut and clamp the limiting ring on the wine jar mold, which is easy to operate.

[0016] To further optimize the technical solution, the driving member includes a supporting oil cylinder fixedly mounted on the outer wall of the bracket, and the output end of the supporting oil cylinder is rotatably hinged to the pusher claw.

[0017] The supporting oil cylinder drives the pusher claw to rotate along the bracket, which is convenient for operation and enables the pusher claw to firmly clamp the limiting ring on the wine jar mold, thereby improving the reliability of use.

[0018] To further optimize the technical solution, the adjusting member includes an adjusting bolt threadably connected to the pusher claw, and the adjusting bolt abuts against the top end of the bracket.

[0019] By adjusting the thread engagement amount between the adjusting bolt and the pusher claw so that it abuts against the bracket, the supporting position of each pusher claw is adjusted so that each pusher claw abuts against the limiting ring on the middle mold, thereby improving the stability and reliability of clamping.

[0020] The beneficial effects of the utility model are:

[0021] 1. When transferring the wine jar mold to the tray, the diameter of the assembly ring is larger than the diameter of the wine jar mold, and the position of the assembly ring is close to the tray, and the claws are deflected upward, which does not interfere with the transfer of the wine jar mold, and is smooth and flexible to use;

[0022] 2. When removing the bottom mold, the assembly ring moves upward, so that the support and the bottom end of the limit ring on the middle mold abut against each other, and the supporting cylinder drives the pusher claw to rotate along the bracket, so that the pusher claw abuts against the top of the limit ring to clamp the limit ring. The assembly ring drives the limit ring to move upward, so that the clamping claw on the middle mold loses its restraint and pops open, and the tray drives the bottom mold to move downward, so that the middle mold and the bottom mold are disconnected, completing the bottom mold removal operation. The operation is simple, flexible and efficient.

[0023] 3. When the supporting cylinder drives the pallet to rise and fall, the pallet drives the support rod to slide along the bracket. The multi-position distribution of the support rod prevents the pallet from rotating, thereby ensuring the stability of the pallet lifting. When the lifting drive drives the assembly ring to rise and fall, the multi-position distribution of the lifting drive makes the lifting of the assembly ring stable and reliable.

DETAILED DESCRIPTION

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Please refer to the attached Figure 2 , Attachment Figure 4-5 The demolding mechanism of the container mold comprises a machine base 1, on which a pallet 2 is lifted and lowered, and the pallet 2 is lifted and lowered with the machine base 1 by means of a supporting oil cylinder 6, and the cylinder seat of the supporting oil cylinder 6 is fixedly installed with the machine base 1, and the output end of the supporting oil cylinder 6 is coaxially assembled with the pallet 2 by means of a cylinder flange, and the cylinder flange is coaxially fixedly installed at the bottom end of the pallet 2, and the end face of the output end of the supporting oil cylinder 6 is arc-shaped and abuts against the inner wall of the cylinder flange, so that the pallet 2 has a certain deflection clearance on the hydraulic cylinder to adapt to the support of the wine jar mold and improve the flexibility of use, and the pallet 2 is lifted and lowered with the machine base 1 by means of a guide assembly, and the guide assembly includes a support rod 7 uniformly fixedly installed along the circumferential direction at the bottom end of the pallet 2, and the support rod 7 is slidably connected with the machine base 1, and the support rod 7 limits the movement of the pallet 2, so that it can move up and down smoothly, avoid its rotation interfering with demolding, and improve the reliability of use;

[0033] Please refer to the attached Figure 2-5 , an assembly ring 3 is coaxially arranged above the tray 2, and the assembly ring 3 is lifted and installed with the machine base 1. The assembly ring 3 is lifted and installed with the machine base 1 by means of a lifting drive member 8, and the lifting drive member 8 is distributed on the machine base 1 along the circumferential direction and fixedly installed with the machine base 1, and the output end of the lifting drive member 8 is fixedly installed with the assembly ring 3, and the lifting drive member 8 is distributed along the circumferential direction. The shell of the lifting drive member 8 is selected from an oil cylinder or an air cylinder, etc. When the lifting drive member 8 runs synchronously, the lifting and lowering of the assembly ring 3 is stable, and the diameter of the assembly ring 3 is larger than the diameter of the wine jar mold, so that the wine jar mold passes through the assembly ring 3 and is placed on the tray 2, and when the wine jar mold is transferred to the tray 2, the lifting drive member 8 contracts, so that the assembly ring 3 is close to the tray 2, so that the transfer of the wine jar mold to the tray 2 is smooth and simple;

[0034] Please refer to the attached Figure 2-6The bottom of the inner ring wall of the assembly ring 3 is detachably installed with a support 4 along the circumferential direction, and the top of the outer ring wall of the assembly ring 3 is hinged with a pusher claw 5 along the circumferential direction. The pusher claw 5 is connected to the assembly ring 3 by means of a bracket 9, and the bracket 9 is rotatably hinged with the pusher claw 5, and the bracket 9 is drivingly connected with the pusher claw 5 by means of a driving member, and the driving member is a supporting cylinder 10 fixedly installed on the outer wall of the bracket 9, and the output end of the supporting cylinder 10 is rotatably hinged with the pusher claw 5. When the bottom mold 13 is removed, the lifting driving member 8 drives the assembly ring 3 to move up, so that the support 4 abuts against the bottom end of the limit ring on the wine jar mold, and then the supporting cylinder 10 drives the pusher claw 5 to rotate along the bracket 9 to a horizontal position and abut against the top end of the limit ring. Then, the pusher claws 5 are all provided with adjusting parts, which include adjusting bolts 11 threadedly connected with the pusher claws 5, and the adjusting bolts 11 are in contact with the top of the bracket 9. By adjusting the thread engagement amount of the adjusting bolts 11 and the pusher claws 5, the pusher claws 5 are in contact with the bracket 9 to adjust the positions of the pusher claws 5, so that the pusher claws 5 are all in contact with the top of the limiting ring, so as to cooperate with the support 4 to clamp the limiting ring, and as the position of the assembly ring 3 moves upward, the limiting ring 15 is driven to move upward along the wine jar mold, so that the claws 14 on the middle mold 12 lose their constraints and pop open, and as the tray 2 moves downward, the middle mold 12 and the bottom mold 13 are disconnected, and the demoulding operation of the bottom mold 13 is completed;

[0035] The working principle of the bottom mold stripping mechanism of the container mold is as follows: when stripping the bottom mold 13, the supporting cylinder 6 supports the tray 2 at a certain height and maintains the position. When the wine jar mold is transferred to the tray 2, the lifting drive 8 contracts to make the assembly ring 3 close to the tray 2. The diameter of the assembly ring 3 is larger than the wine jar mold, and the claw 5 on the top of the assembly ring 3 is tilted upward, which does not interfere with the transfer of the wine jar mold and is flexible to use. When demolding begins, the assembly ring 3 moves up to make the support 4 abut against the bottom end of the limiting ring 15 on the wine jar mold, and the supporting cylinder 10 drives the claw 5 to deflect to a horizontal position and abut against the top of the limiting ring 15 to clamp the limiting ring 15. After the assembly ring 3 drives the limiting ring 15 to move up, the claw 14 on the middle mold 12 loses its constraint and pops open. At this time, the supporting cylinder 6 drives the tray 2 to move down, so that the bottom mold 13 is disconnected from the middle mold 12, and the demolding work of the bottom mold 13 is completed. The operation is simple and labor-saving, and the continuous demolding operation is efficient.
