TECHNICAL FIELD
[0001] The utility model belongs to mould technical field, especially relate to a production mould of inverted bottle holder packaging box. BACKGROUND
[0002] The production mould of inverted bottle holder packaging box is a key tool for manufacturing inverted bottle holder packaging boxes. This mould is specially designed to produce inner and outer holder structures that can place bottles upside down and provide stable support. In the production mould of inverted bottle holder packaging box, guide pillars and guide sleeves are key components for guiding the opening and closing of the movable mould (lower mould) and the fixed mould (upper mould), ensuring accurate alignment and smooth movement of the mould during injection molding. However, in actual application, the existing guide pillars and guide sleeves have some shortcomings and deficiencies, affecting the performance and service life of the mould. Due to frequent opening and closing actions, guide pillars and guide sleeves bear a lot of mechanical stress, which can easily cause wear and deformation, especially in high-precision moulds, so it is necessary to regularly replace and maintain guide pillars and guide sleeves. However, in the prior art, guide pillars and guide sleeves are generally fixed by screws or pressure plates, so they are difficult to disassemble, increasing the difficulty of maintenance and replacement. Therefore, a new structure is proposed to solve the above problems. SUMMARY
[0003] In view of the deficiencies of the prior art, the utility model aims to provide a production mould of inverted bottle holder packaging box to solve the problems raised in the background.
[0004] The utility model discloses the following technical scheme realizes: a production mould of inverted bottle holder packaging box, comprising: upper mould, guide pillar assembly and guide sleeve assembly, four groups of guide pillar assemblies for butting with guide sleeve assembly are installed at the bottom four corners of the upper mould, the guide pillar assembly includes a quick release rod that can be quickly released and replaced,
[0005] The quick release rod top is equipped with the screw rod, the quick release rod top is equipped with the fixed rod, the fixed rod bottom is equipped with the screw hole two that is used for and the screw rod thread connection, the guide sleeve assembly includes a screw sleeve that can be quickly released and replaced.
[0006] As a preferred embodiment, the quick release rod is internally provided with an inner cylinder, the outer side of the inner cylinder is sleeved with a return spring, the lower side of the inner cylinder is provided with a pressing rod, and the upper side of the pressing rod is located in the inner cylinder.
[0007] In a preferred embodiment, the top of the return spring is fixed to the upper inner side of the quick-release rod, and the bottom of the return spring is fixed to the bottom of the pressure rod. The radius of the bottom of the pressure rod is the same as the radius of the quick-release rod. The pressure rod is subjected to a reverse thrust and moves upward along the inner side of the inner cylinder, squeezing the return spring to compress and store force. When demolding, the four sets of return springs rebound and push the bottom of the pressure rod downward, and push the bottom of the pressure rod downward to the lower inner side of the screw sleeve, thereby generating a reverse thrust to push the pressure rod upward, so that the four sets of guide post assemblies push the upper mold and the lower mold to separate, thus facilitating demolding.
