[0002] As a common packaging material in daily life, a large number of identical molds are required in the production process of plastic bottles, and at the same time, extremely high requirements are placed on the accuracy and quality of the molds. The quality of the molds directly affects the molding quality, dimensional stability, and appearance beauty of plastic bottles. Therefore, accurate and efficient detection of plastic bottle molds is a key step to ensure product quality.

[0003] During the production process of plastic bottles, after the bottom of the bottle is formed, water needs to be passed through the inside of the bottom mold base to facilitate the separation of the bottom of the plastic bottle from the bottom mold base. After long-term use, the internal pipes of the bottom mold base are prone to blockage, and replacing the bottom mold base easily causes deformation of the bottom mold base, resulting in poor cooling effect of the bottom mold base, making it difficult to demold the bottom of the plastic bottle and even affecting the product quality of the plastic bottle. Therefore, it is necessary to regularly detect the bottom mold base to ensure normal production.

[0004] Using tools such as calipers for mold detection is inefficient and cannot meet the detection work of a large number of molds. At the same time, it is difficult to directly measure and detect the internal pipes of the bottom mold base. Content of the Utility Model

[0032] The embodiments of the present utility model will be described below with reference to the drawings.

[0033] A bottom die base detection device includes a die base 1.

[0034] The die base 1 is provided with a support surface 131, a connection surface, a first detection hole 111, and a second detection hole 112. The support surface 131 and the connection surface are distributed directly opposite to each other, one above the other. The first detection hole 111 is a circular through hole vertically provided on the support surface 131, and the second detection hole 112 is a circular through hole vertically provided on the connection surface. The first detection hole 111 and the second detection hole 112 are coaxially arranged, and the circular through holes are all used for the joint of the measured die 2 to penetrate.

[0035] A detection pipeline 12 is arranged inside the die base 1. One end of the detection pipeline 12 is communicated with the second detection hole 112, and the other end of the detection pipeline 12 is connected to an external water pipe. The detection pipeline 12 is used for passing water to detect the connectivity of the internal pipeline of the measured die 2.

[0036] Such as Figure 4As shown, the mold 2 to be measured is the bottom mold base used for plastic bottle production. The mold 2 to be measured is provided with a joint 21 connected to the water supply pipeline and an internal pipeline for water cooling. The present utility model proposes a bottom mold base detection device. As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, the bottom mold base detection device is used to detect whether the joint 21 of the mold 2 to be measured is deformed and deviated from the axis and the connectivity of the internal pipeline. When in use, the mold 2 to be measured is passed through the first detection hole 111 and the second detection hole 112. When the mold 2 to be measured is deformed and deviated from the axis, it cannot pass through the first detection hole 111 and the second detection hole 112 at the same time. At this time, it is determined that the mold 2 to be measured is severely deformed and cannot be used continuously; when the mold 2 to be measured normally passes through the first detection hole 111 and the second detection hole 112 at the same time, the water passing holes on the mold 2 to be measured communicate with the internal pipeline of the mold base 1, and the detection pipeline 12 of the mold 2 to be measured is connected to the external water supply pipeline, and water can be passed through to detect the connectivity of the internal pipeline of the mold 2 to be measured. With this structure, it can be detected whether the joint 21 outside the mold 2 to be measured is deformed, and if there is no deformation, it can further detect whether the pipeline inside the mold 2 to be measured is blocked, solving the problem of being unable to quickly detect the mold 2 to be measured.

[0037] As Figure 3 shown, in an embodiment, the mold 2 to be measured is vertically placed on the support surface 131, one side of the mold 2 to be measured is closely attached to the support surface 131, and the joint 21 of the mold 2 to be measured passes through the first detection hole 111 and the second detection hole 112. When the joint 21 is damaged and deformed, the mold 2 to be measured cannot be closely attached to the support surface 131, and the joint 21 of the mold 2 to be measured cannot pass through the first detection hole 111 and the second detection hole 112 at the same time. With this structure, the perpendicularity of the joint 21 of the mold 2 to be measured can be conveniently detected.

[0038] Preferably, the mold base 1 includes a top plate 13, a bottom plate 14 and at least two columns. The top plate 13 and the bottom plate 14 are horizontally spaced apart directly opposite each other, one above the other. The two columns are equidistantly arranged between the top plate 13 and the bottom plate 14. The columns are used to connect the top plate 13 and the bottom plate 14. The top of the top plate 13 is horizontally provided with the support surface 131, and the bottom plate 14 is provided with a horizontally arranged connection surface. The first detection hole 111 is a circular through hole vertically arranged on the top plate 13, and the second detection hole 112 is a circular through hole vertically arranged on the bottom plate 14.

[0039] As Figure 3 and Figure 6 shown, with this structure, the top plate and the bottom plate are fixed by the columns on both sides, and the top plate and the bottom plate are spaced apart up and down. The deformation condition of the mold 2 to be measured can be observed through the interval between the top plate 13 and the bottom plate 14, providing a reference for the subsequent repair of the mold to be measured.

[0040] Preferably, the top plate 13 is provided with a third detection hole 113, and the third detection hole 113 is a straight hole perpendicular to the top plate 13.

[0041] Such as Figure 4 and Figure 6 , in an embodiment, the top plate 13 is horizontally arranged, the third detection hole 113 is a vertically arranged cylindrical straight through hole, the mold 2 to be measured is provided with a cylindrical fixed straight rod 22, when the mold 2 to be measured is placed on the top plate 13, the fixed straight rod 22 of the mold 2 to be measured extends into the third detection hole 113, when the fixed straight rod 22 is damaged and deformed, the fixed straight rod 22 cannot completely extend into the third detection hole 113; when the fixed straight rod 22 normally extends into the third detection hole 113, the third detection hole 113 cooperates with the first detection hole 111 to detect whether the position of the joint 21 of the mold 2 to be measured is appropriate, when the position is inappropriate, the fixed straight rod 22 and the joint 21 cannot simultaneously extend into the third detection hole 113 and the first detection hole 111 respectively.

[0042] In an embodiment, the water passing performance of the mold 2 to be measured is detected by pressing the mold 2 to be measured with a hand press.

[0043] Preferably, a locking mechanism 3 is further included, and the locking mechanism 3 is used to lock the mold 2 to be measured.

[0044] Such as Figure 1 and Figure 3 , in a more preferred embodiment, the locking mechanism 3 is used to fix and lock the mold 2 to be measured, simulating the use situation of the mold 2 to be measured fixed on an external water passing device.

[0045] Preferably, the locking mechanism 3 includes a fixing piece 31, a fixing bolt, a fixing rod 32, a locking hole 114 and a locking groove 115. The locking hole 114 and the locking groove 115 are respectively arranged on the column. The fixing piece 31 is provided with a fixing hole 33. The locking hole 114 and the fixing bolt are provided with matching threads. The fixing bolt passes through the fixing hole 33 to screw the fixing piece 31 onto the locking hole 114. The fixing piece 31 and the locking groove 115 cooperate to clamp the fixing rod 32, and the fixing rod 32 is used to limit the mold 2 to be measured.

[0046] Such as Figure 1 and Figure 3 , in an embodiment, the mold 2 to be measured is vertically placed on the mold base 1. The mold 2 to be measured is provided with a fixing groove 23. The fixing bolt screws the fixing piece 31 tightly. The fixing piece 31 and the locking groove 115 clamp the fixing rod 32, and the fixing rod 32 presses tightly into the fixing groove 23 to limit and lock the mold 2 to be measured.

[0047] Preferably, the fixing rod 32 is cylindrical, and a recessed portion 34 with a reduced diameter is provided in the middle section of the fixing rod 32. The recessed portion 34 is matched with the shape of the fixing groove 23 of the mold 2 to be measured.

[0048] As Figure 3 and Figure 4 , the mold 2 to be measured is provided with a fixing groove 23. When the mold 2 to be measured is connected to an external water supply device, a pin provided on the water supply device passes through the fixing groove 23 to fix the mold 2 to be measured. The recessed portion 34 of the fixing rod 32 is used to simulate the pin of the external water supply device, so as to conveniently detect whether the fixing groove 23 of the mold 2 to be measured is deformed.

[0049] At the same time, the lower side of the recessed portion 34 in the middle section of the fixing rod 32 abuts against the lower inclined surface of the fixing groove 23 of the mold 2 to be measured, pressing the mold 2 to be measured downward, so that a sealed connection is formed between the water connection joint 21 at the bottom of the mold 2 to be measured and the mold base 1.

[0050] Preferably, the mold base 1 further includes an interface detection unit 15. The interface detection unit 15 is disposed opposite to the second detection hole 112 and is located below the second detection hole 112. The interface detection unit 15, the second detection hole 112, and the detection pipeline 12 are communicated with each other. The interface detection unit 15 is used to detect the sealing performance of the interface of the water connection joint 21 of the mold 2 to be measured.

[0051] In an embodiment, the mold 2 to be measured is vertically placed on the mold base 1. The interface detection unit 15 is located below the second detection hole 112. When the water connection joint 21 of the mold 2 to be measured passes through the second detection hole 112, the interface of the water connection joint is pressed downward against the interface detection unit 15. When the interface is damaged, water leakage will occur during the water passing detection, solving the problem of being unable to detect the sealing performance of the interface.

[0052] Preferably, the interface detection unit 15 includes an annular groove 151 and an annular protrusion 152, and a sealing gasket is disposed in the annular groove 151.

[0053] When the mold 2 to be measured is connected to an external water supply device, slight water leakage can be compensated by methods such as adding a sealing ring and using waterproof tape. By adopting this structure, sealing gaskets with different thicknesses are provided to simulate the sealing conditions of actual interfaces.

[0054] As Figure 5 , in an embodiment, the interface detection unit 15 is provided with an annular groove 151 and an annular protrusion 152, simulating the interface part of an external water supply pipeline. When the interface of the mold 2 to be measured is severely deformed, it cannot be inserted into the annular groove 151. When the interface of the mold 2 to be measured is slightly deformed, water leakage will occur in the water passing detection of the interface detection unit 15.

[0055] Preferably, the mold base 1 is divided into an upper member 11 and a lower member 16. The upper member 11 is installed above the lower member 16. The interface detection unit 15 and the detection pipeline 12 are respectively arranged on the lower member 16, and the support surface 131, the connection surface, the first detection hole 111 and the second detection hole 112 are respectively arranged on the upper member 11.

[0056] As Figure 2 and Figure 5 , in an embodiment, the relatively difficult-to-machine interface detection unit 15 and the detection pipeline 12 are arranged on the lower member 16. After the lower member 16 is separately machined and completed, it is welded and fixed to the bottom of the upper member 11. And the second detection hole 112 is communicated with the outlet end of the detection pipeline, and the interface detection unit 15 is arranged directly opposite to the second detection hole 112. With this structure, only simple through-hole structures arranged in the same direction need to be machined on the top plate 13 and the bottom plate 14 of the mold. The top plate 13 and the bottom plate 14 can be made of strong and durable materials, reducing the machining difficulty of the mold base 1 and improving the overall service life of the bottom mold base detection device.

[0057] In an embodiment, the bottom mold base detection device is provided with a set of first detection holes 111, second detection holes 112, detection pipelines 12 and interface detection units 15 for detecting the water inlet interface of the mold 2 to be measured, and the water outlet interface of the mold to be measured is left empty and directly discharged.

[0058] Preferably, there are two first detection holes 111, second detection holes 112, detection pipelines 12 and interface detection units 15 respectively, corresponding to the two connectors 21 of the mold 2 to be measured.

[0059] As Figure 1 , Figure 2 and Figure 4 , in a more preferred embodiment, there are two first detection holes 111, second detection holes 112, detection pipelines 12 and interface detection units 15 respectively. The mold 2 to be measured is provided with two water passing connectors 21 in the same direction. The two water passing connectors 21 are respectively used to connect the external water inlet pipeline and the water outlet pipeline, and the two water passing connectors 21 can be detected simultaneously to improve the detection efficiency.
