Description

Device for measuring capacity of inner cavity of glass mold

Technical Field

The invention belongs to the technical field of glass mold detection devices, and particularly relates to a device for measuring the capacity of an inner cavity of a glass mold.

Background

Glass molds are equipment for making glass containers such as beer bottles, red wine bottles, soda bottles, daily life cosmetic bottles, condiment bottles, and various beverage bottles, and the like. The glass mold is generally of a two-mold structure symmetrical to each other, and for this purpose, see chinese patent application publication nos. CN101298355A (mold for making glass containers), CN101298356a (mold for making glass containers), CN101298357a (mold for processing glass containers), CN101298358A (mold for processing glass containers), CN101298359a (mold for processing glass containers), CN101941791a (mold for making glass containers for bottles and cans), grant publication No. CN102515471B (mold for making glass containers for bottles and cans), and US patent No. 2006/0213632A1 (glass molding mold), etc.

As is known in the art, the cavity capacity of a glass mold is sought to be accurate in the manufacture of glass molds because the shape of the glass container depends on the cavity of the glass mold, which in turn depends on the shape of the glass container. However, since the processing of the glass mold is complicated, for example, turning, milling, planing, carving, polishing, etc., it is difficult to avoid the situation that the capacity of the inner cavity of the glass mold exceeds the capacity tolerance required in the initial design and to correspondingly out-of-tolerance the glass container processed by the glass mold with the out-of-tolerance capacity in a linked reaction manner. When glass container manufacturers feed information about out of tolerance (out of tolerance, the same applies below) of glass molds back to the glass mold manufacturers, it is often too late. Therefore, the glass mold manufacturer can prevent the problem only by effectively detecting the capacity of the inner cavity of the glass mold before the glass mold is supplied to the glass container manufacturer. However, since the glass mold cavity typically has complex patterns, text, etc., it is difficult or even impossible to directly perform the measurement by conventional tools.

The prior art method for measuring the capacity of the inner cavity of the glass die mainly comprises the following two steps: firstly, measuring the capacity (also called as volume) of an inner cavity of a glass die by utilizing a reverse engineering scanning principle; and secondly, measuring the capacity of the inner cavity of the glass die by using a weighing method. The former needs to be provided with a scanner which is high enough to be prohibitive, the scanner is used for carrying out 3D scanning on the inner cavity of the glass, and the capacity is processed and calculated by special software, so that the method has long measuring time and needs to be operated by a senior technician, and is not suitable for the conditions of more varieties (different specifications) and small batches of glass molds, namely, the detection requirement of daily production cannot be met; a typical example of the latter is "a method for determining the capacity of a glass mold cavity" as recommended by the invention of patent application publication No. CN106017600a, which is to fill the glass mold cavity with water, and then measure the capacity by an empirical conversion formula and compare it with the specifications of the design drawing (paragraphs 0010 to 0020), the disadvantage of this patent is: a large amount of human participation is needed, such as the air hole of the inner cavity of the die and the joint surface (also called the joint surface) of the two half dies are required to be coated with grease and sealed before water injection, and redundant water is required to be pumped out by a medical needle tube after the water injection is completed, and cleaning treatment is required to be carried out on the die after detection is completed, so that the more human participation factors are, the more difficult the accuracy of capacity measurement is ensured, the labor intensity of a measurer is high, the efficiency is low, and the method is suitable for pumping measurement and is not suitable for comprehensive measurement.

From the standpoint of the industrial desire to make it necessary to use the device, it is necessary to search for a device which is easy to operate, easy to clamp, economical and inexpensive and can meet the use requirements for measuring the capacity of the inner cavity of the glass mold, for which purpose the applicant has made repeated and advantageous attempts, and finally has formed the technical solutions to be described below and has made simulation tests in the applicant's test center with security measures taken, and the results have proved to be viable.

The applicant has mentioned in the above description of the operation of the water filling mechanism 4 that the piston 46 is displaced forwardly with the screw piston stem 47, and water in the reservoir 3 is admitted into the cylinder cavity 451 via the three-way connection 334, the water filling pipe 4521 and the cylinder cavity water filling pipe connection 452 in sequence. In this process, since the screw piston rod 47 moves the screw piston rod stroke signal collector 81 fixed to the front end thereof when it is displaced forward, the amount of forward displacement of the screw piston rod 47 is collected by the screw piston rod stroke signal collector 81, and the signal is fed back to the linear digital sensor 84, the signal is fed back to the linear measuring device 86 by the linear digital sensor 84, the signal is fed back to the controller 87 (also referred to as "PC") by the linear measuring device 86, and the volume in the water injection cylinder cavity 451 is displayed by the aforementioned display 10 after being processed by the controller 87. Under the reverse operation of the cylinder driving motor 42 and in the state of closing the water inlet valve 331 and opening the water outlet valve 332, the piston 46 is displaced backward in order to sequentially feed the water in the cylinder chamber 451 through the cylinder chamber water injection pipe connector 452, the water injection pipe 4521, the water outlet valve 332 and the water reservoir water outlet pipe 33 into the lifting screw chamber 521 of the lifting screw 52, and then into the spout 53 and injected into the gum cover 40 (shown in fig. 4) in the cavity 301 of the glass mold 30 to be tested placed in the clamped state by the water injection hole 531 on the spout 53, because the spout 53 is extended into the gum cover 40. The volume of the sleeve 40 filled with water is exactly the volume shown by the display and is the volume of the mold cavity 301. When the nozzle 53 fills the gum cover 40 to a pressure of 8bar (which is sensed by the pressure sensor 45211), the cylinder driving motor 42 stops, and the volume is calculated and reflected by the water injection mechanism water injection amount response means 8. Preferably, after the injection of the glue jacket 40 is completed, the glue jacket 40 is removed and transferred to a standard mold, and compared with the standard mold (also referred to as "correction mold") so as to fully ensure the accuracy of the volume of the cavity 301 of the glass mold 30 to be tested.

According to the common general knowledge, the specifications of the glass mold are different, so the nozzle 53 has different specifications, and the rubber sleeve 40 is the same.

Since a stop collar cavity 92 and a glue collar opening matching cavity 93 are formed on opposite sides of the pair of press-fit clips 9, when the press-fit clips 9 are assembled in the manner shown in fig. 4, the stop collar 523 at the upper stroke limit position of the lifting screw is matched with the stop collar cavity 92, and after the glue collar 40 is sleeved outside the spray pipe 53, the glue collar opening 401 at the upper part of the glue collar 40 is matched with the seal ring 527 preset at the lower end of the lifting screw 52, i.e. below the stop collar 523 at the upper stroke limit position of the lifting screw, so that when the pair of press-fit clips 9 are interlocked by the snap ring 91, the glue collar opening 401 of the glue collar 40 is in a good sealing state. The state in which the glass mold 30 to be measured is clamped by the left and right clamping shoes 65, 66 is schematically shown in fig. 2.
