Description

Blowing machine mold safety fixture

This creation is a mold safety tool for blow molding machines, especially a mold safety tool for blow molding machine that can replace the mold and prevent the blow molding machine from automatically closing.

Baote bottle system currently uses the universal container for liquid. The bottle is light, tough and airtight. It allows the bottle to be carried and the liquid does not overflow. Plus acid and alkali can hold carbonated water such as soda. Beverages, in order to make consumers happy to distinguish, the appearance of the PET bottles with different liquids will be different, the production line of the food factory must meet the machines that can make different types of PET bottles.

The existing blow molding machine can produce a PET bottle by means of blow molding. The blow molding machine comprises a machine table, a base, a two-opening mold and a blowing unit, and the base is arranged on the machine table and adjacent to the machine table. The bottom end of the two opening and closing molds are pivotally coupled to the machine table, and the two opening and closing molds are rotatably coupled. The other ends of the two opening and closing molds respectively have a male fastener and a female fastener. The fastener can extend into the female fastener and has a locking opening on the male fastener, the female fastening component has a clamping pin, and the clamping pin passes through the locking opening to fix the two opening and closing molds. The air blowing unit is disposed on the machine platform and located above the two opening and closing molds. The worker can install the two mold halves on the two opening and closing molds, install a bottom mold on the base, and then place a plastic embryo. Between the two mold halves, the two split molds are combined and locked, the two mold halves sandwich the plastic embryo and the bottom of the mold halves abut the bottom mold, and the blow unit blows a bottle program, the air blowing unit blows air into the plastic embryo between the two mold halves, the plastic embryo expands and sticks according to the inner contour of the two mold halves The inner contour of the mold half and the contact with the bottom mold can be made into a PET bottle, and the worker wants to manufacture a PET bottle of different appearances, and only needs to open the two opening and closing mold, and the two mold halves and the When the bottom mold is replaced, the two mold halves of different inner contours can be replaced to complete the production of different types of PET bottles.

However, the two opening and closing mold system of the bottle blowing machine can be automatically closed, and when the worker opens the two opening and closing molds to replace the two mold halves of different inner contours, two people need to work together, and one person holds the two by hand. When the mold is opened and closed, the other person replaces the two mold halves, and the staff who assisted the two molds open the mold to the two sides, and the worker is likely to extend into the female fastener during the opening process and receive The clamping pin is clamped, and the worker who replaces the two mold halves needs to replace the two mold halves in the two opening and closing molds. The working positions of the two people interfere with each other and labor is required, and the staff opens the two opening and closing molds. It is laborious and the two opening and closing molds are automatically closed, and there may be a risk of accidents caused by pinching the workers.

The main purpose of this creation is to provide a mold safety tool for the blow molding machine, so as to improve the automatic closing of the opening and closing mold of the existing blowing machine, which causes the problem of replacing the two mold halves, which is labor intensive, inconvenient to replace, and prone to pinch accidents.

In order to achieve the pre-existing purpose, the creation of the blow molding machine mold safety jig is set in a blow molding machine and is used to assist the replacement of the two mold halves and the bottom mold and comprises: an in-situ assembly, the in-situ assembly extending into the blowing a female fastener of the bottle machine, the protruding component comprises a holding plate and a plurality of extending portions, wherein the plurality of extending portions are arranged at intervals in the holding plate, and the plurality of extending portions can extend into the a female fastener; a partitioning component is disposed on the top of the blow molding machine, the partitioning assembly includes an abutting plate and a partitioning block, the abutting plate has two abutting faces, and the two abutting faces Located at the bottom of the abutting plate and adjacent to the two sides of the abutting plate, the partitioning block is disposed at the bottom of the abutting plate and between the two abutting faces, and the two sides of the separating block respectively have a partitioning surface respectively adjoining the two abutting faces; and a distracting component, the distracting component is disposed on the base of the bottle blowing machine, and the distracting component comprises a spanning plate, the brace The opening plate is disposed on the base, and each of the two sides of the opening plate has an opening wall.

The creation of the blow molding machine mold safety fixture can prevent the worker from opening the two opening and closing molds when the worker replaces the mold of the blowing machine by extending the insertion assembly into the female fastener of the blowing machine. Inadvertently extending into the female fastener, effectively improving the safety of the replacement mold, avoiding the accident of the finger being pinched, and placing the two opening and closing molds through the partitioning assembly, or the distracting component is disposed on the base The support and the opening and closing of the two molds can save the staff to maintain the strength of the two opening and closing molds, and also allow a staff member to independently complete the operation of replacing the molds, saving manpower and reducing labor costs.
