Technical Field

[0001] The present invention relates to the technical field of mold production, and in particular to a mold appearance detection device. Background Art

[0002] During the mold production process, the appearance of the mold needs to be inspected to find out whether the mold has defects; an existing mold appearance inspection method mainly places the mold on a test bench, then dips a brush in blue cyanide oil, and then uses a brush to apply blue cyanide oil to the surface of mold A, so as to directly observe whether there are concave and convex defects on the mold surface, and then close and separate mold A and mold B, and then observe the adhesion of blue cyanide oil on the mold surface, so as to detect the tightness of the surface of the joint of objects A and B. When using the above appearance inspection method, because the mold surface is irregular and there are depressions in many places, the method of applying oil with a brush dipped in blue cyanide oil takes a long time to apply blue cyanide oil to the entire mold, which is inefficient. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcoming of low efficiency of manual application of blue pigment oil in the prior art, and to propose a mold appearance detection device.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

The drum is made of plastic, and a plurality of magnetic strips are fixed circumferentially on the outer surface of the inner cylinder. The inner surface of the flexible skin is sprayed with a magnetic coating, and the magnetic strips and the magnetic coating attract each other.

[0008] Preferably, the horizontal axis is hollow, a water suction pipe is provided in the drum, the bottom end of the water suction pipe is arranged close to the lowest point of the drum, the water suction pipe is connected to the horizontal axis, one end of the horizontal axis is sealed, and the other end of the horizontal axis is used to connect to a liquid pumping device, and the liquid pumping device is used to discharge liquid into the drum or pump out liquid in the drum.

[0009] Preferably, a blue dandruff oiler is provided above the drum and fixed on a bracket. The blue dandruff oiler comprises a box body, the top of the box body is opened, the box body is rectangular, the box body is arranged parallel to the drum, and a plurality of oil outlet holes are opened through the bottom of the box body.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1: Reference Figure 1-11A mold appearance inspection device includes a test platform 1, on which a roller 5 is horizontally placed, and the two ends of the roller 5 are sealed. A flexible skin 6 is sleeved on the roller 5, and the flexible skin 6 is cylindrical as a whole. The edges of the two ends of the flexible skin 6 are fixed to the two end surfaces of the roller 5. A plurality of water-permeable holes 11 are opened on the roller 5 along the circumferential direction. A horizontal shaft 4 is also coaxially rotatably installed on the roller 5, and the two ends of the horizontal shaft 4 are fixed on the bracket 3. The bracket 3 is fixed on the linear moving device 2, and the linear moving device 2 is fixed on the test platform 1. The linear moving device 2 is used to drive the roller 5 to make a linear reciprocating movement on the test platform 1. The roller 5 is connected to a motor 10 for driving the roller 5 to rotate. The motor 10 is fixed on the bracket 3, and the roller 5 stores liquid 17. The bracket 3 has a height adjustment function. By adjusting the height of the bracket 3, the height of the roller 5 is adjusted, so that the molds of different thicknesses on the test platform 1 are oiled.

[0030] The outer surface of the flexible skin 6 is provided with a felt layer 16. The felt layer 16 can better absorb the blue pigment oil so that the blue pigment oil will not fall off during the rotation of the drum 5, and can better fit the mold surface when rubbing against the mold surface.

[0031] An inner cylinder 12 is coaxially fixed inside the drum 5. A notch is provided on the inner cylinder 12 toward the detection platform 1, so that the inner cylinder 12 is C-shaped. The drum 5 is made of plastic. A plurality of magnetic strips 14 are fixed to the outer surface of the inner cylinder 12 along the circumferential direction. A magnetic coating 15 is sprayed on the inner surface of the flexible skin 6. The magnetic strips 14 and the magnetic coating 15 attract each other. By providing the C-shaped inner cylinder 12 and the magnetic strips 14, the flexible skin 6 and the corresponding part of the inner cylinder 12 will be attached to the surface of the drum 5 due to the suction force of the plurality of magnetic strips 14 during the rotation process, so that sufficient friction is maintained between the flexible skin 6 and the drum 5. Only when the flexible skin 6 moves to the notch and loses the magnetic force, will it bulge under the action of the liquid 17 at the bottom of the drum 5.

[0032] The horizontal axis 4 is hollow, and a water suction pipe 13 is arranged in the drum 5. The bottom end of the water suction pipe 13 is arranged near the lowest point of the drum 5. The water suction pipe 13 is connected to the horizontal axis 4. One end of the horizontal axis 4 is sealed, and the other end of the horizontal axis 4 is used to connect a liquid 17 pumping device. The liquid 17 can be discharged into the inner cylinder 12 or the liquid 17 in the inner cylinder 12 can be sucked out by the liquid pumping device in conjunction with the horizontal axis 4 and the water suction pipe 13.

[0033] An electric heating device is provided in the drum 5. The electric heating device is used to heat the liquid 17; when the ambient temperature is low, the flexible leather cover on the surface of the drum 5 may become hard and easily damaged, and the blue dart oil at low temperature becomes viscous and cannot be evenly applied on the surface of the flexible skin 6. For this reason, an electric heating device is provided to heat the liquid 17 of the drum 5, and the liquid 17 evenly transfers the heat to the surface of the moving drum 5, so that the drum 5 and the flexible skin 6 are heated, thereby obtaining a better blue dart oil application effect.

[0034] Example 2: Reference Figure 1-2 As another preferred embodiment of the present invention, the difference from the embodiment 1 is that a blue damask oiler is arranged above the roller 5, the blue damask oiler is fixed on the bracket 3, and the blue damask oiler includes a box body 7, the top of the box body 7 is an opening, the box body 7 is rectangular, the box body 7 is arranged parallel to the roller 5, and a plurality of oil outlet holes are opened through the bottom of the box body 7. By providing the blue damask oiler, the surface of the flexible skin 6 can be automatically oiled.

[0035] A pressure plate 8 is installed in the box body 7, and a cylinder 9 is connected above the pressure plate 8. The cylinder 9 is vertically arranged and fixedly connected to the bracket 3. After the box body 7 is filled with blue cyanide oil, the pressure plate 8 is pushed downward by the cylinder 9 to move slowly and uniformly, so that the blue cyanide oil in the box body 7 is squeezed out through the oil outlet hole at the bottom of the box body 7.

[0036] A scraper is respectively arranged on both sides of the blue tan oil lubricator, and the scrapers are arranged corresponding to the roller 5. A gap is left between the two scraper ends and the outer felt layer 16 of the flexible skin 6, so that the blue tan oil on the felt layer 16 can be scraped evenly.

[0037] The overall workflow of the present invention is as follows:

[0038] The mold 18 is placed on the test bench 1, and then the height of the bracket 3 is adjusted so that the bottom of the drum 5 is flush with the surface of the test bench 1. Then the linear moving device 2 is controlled to drive the entire drum 5 to move above the mold 18. At this time, a small amount of liquid 17 is injected into the drum 5. At this time, the liquid 17 gathers at the bottom of the drum 5. Since the drum 5 is provided with a water-permeable hole 11 and the outside of the drum 5 is covered with a flexible skin 6, as shown in the attached Fig.10As shown, when the surface of the mold 18 below the roller 5 is in a flat state, the flexible skin 6 close to the surface of the mold 18 will expand downward under the gravity of the liquid 17, so that the flexible skin 6 can obtain a larger contact area with the surface of the mold 18; at this time, the motor 10 and the blue tan oil oiler are started, and the motor 10 drives the roller 5 to rotate, and the rolling drives the flexible skin 6 to rotate. When the flexible skin 6 rotates to the blue tan oil oiler, its surface will be coated with blue tan oil. When it continues to rotate to the bottom of the roller 5, since it is in an expanded state, the blue tan oil can be evenly coated on the surface of the mold 18. At this time, the linear motion device 2 is controlled to drive the rotating roller 5 to move linearly on the surface of the mold 18, so that the blue tan oil can be quickly and widely coated on the surface of the mold 18; as shown in the attached figure Fig.11 As shown, during the process of the roller 5 coating the surface of the mold 18, when the bottom of the roller 5 passes over the concave surface of the mold 18, under the action of gravity, the liquid 17 at the bottom of the roller 5 will cause the flexible skin 6 to sink into the concave surface, so that the concave surface of the mold 18 can be coated.
