Abstract
Description
Technical Field
[0001] This utility model relates to the field of sandblasting tooling structure technology, specifically to a tooling structure for sandblasting a ring structure. Background Technology
[0002] A vapor chamber is a device used to dissipate heat from heat-generating electronic components in electrical appliances. It is typically made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. Generally, a layer of thermally conductive silicone grease is applied to the contact surface between the electronic component and the vapor chamber during use. This allows the heat generated by the component to be more effectively conducted to the vapor chamber, and then dissipated into the surrounding air. A sandblasting machine uses abrasive particles to impact and cut the surface of a workpiece, achieving a certain level of cleanliness and varying roughness, thereby improving the mechanical properties of the workpiece surface.
[0003] A patent with publication number CN221871658U is disclosed in the prior art. The solution includes a worktable, a sandblasting chamber fixedly connected to the top of the worktable, an opening on the bottom side of the sandblasting chamber, an electric push rod embedded at one end of the worktable, a groove in the middle of the top of the worktable, a slider slidably connected in the groove, a servo motor fixedly connected to the top of the slider, the output shaft of the servo motor fixedly connected to the placement table, a baffle assembly installed at the opening of the sandblasting chamber, a sandblasting assembly installed inside the sandblasting chamber, and an adjustment assembly fixedly installed on one side of the sandblasting assembly inside the sandblasting chamber. The baffle assembly can prevent abrasive from splashing out of the sandblasting chamber during the sandblasting process, and the adjustment assembly allows the arc frame to swing, thereby adjusting the position and sandblasting angle of the sandblasting head, thus facilitating a more comprehensive sandblasting process on the heat spreader placed on the surface of the placement table, effectively improving the processing efficiency and processing effect of the heat spreader.
[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:
[0005] First, the traditional cavity-type fixing method cannot accurately sandblast the edge area, resulting in discoloration and poor appearance. The newly made cavity-type fixing tooling fits tightly and is difficult to remove and place.
[0006] Secondly, with the traditional cavity-type fixing method, the tooling needs to be replaced frequently due to wear after a period of use. The product may become loose when placed in the cavity, and fly out of the tooling during sandblasting, causing the product to be damaged by collision.
[0007] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a tooling structure for sandblasting annular structures. This structure solves the problems of traditional cavity-type fixing methods, which cannot accurately cover the edge areas, resulting in color variations and poor appearance; the newly made cavity-type fixing tooling is tight and difficult to place and remove; and the traditional cavity-type fixing method requires frequent tooling replacement due to wear after a period of use, and the product may loosen when placed in the cavity, or fly out of the tooling during sandblasting, causing collision damage.
[0009] To achieve the above objectives, the present invention provides the following technical solution.
[0010] The tooling structure for sandblasting a ring structure includes a supporting tooling, on which several sand-flowing holes are distributed in a matrix. An upper product outer frame positioning groove is opened on the upper edge of the sand-flowing holes, and several product inner frame positioning posts are fixedly connected in parallel in the upper product outer frame positioning groove.
[0011] As an optimized solution, a positioning groove for the lower product outer frame is provided on the lower edge of the sand flow hole.
[0012] As an optimized solution, the lower end of the product inner frame positioning post passes through the lower product outer frame positioning groove and extends downwards.
[0013] As an optimized solution, an insertion hole is provided through the upper product outer frame positioning groove and the lower product outer frame positioning groove, and the product inner frame positioning post is inserted into the insertion hole.
[0014] As an optimized solution, the positioning posts of the product's inner frame are flexible columns.
[0015] As an optimized solution, the depth of the positioning groove of the upper product frame and the positioning groove of the lower product frame is 0.1-0.3mm.
[0016] As an optimized solution, the dimensions of the upper product outer frame positioning groove and the lower product outer frame positioning groove are 0.01-0.03mm larger than the product outer frame dimensions.
[0017] As an optimized solution, the sand flow hole is rectangular in shape, and the four corners of the sand flow hole are provided with inwardly protruding support sections.
[0018] As an optimized solution, the product's inner frame positioning posts are provided with four, which are located at the four corners of the sand flow holes.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] Because the support fixture has been changed from a cavity type to a hollow type, it better meets the sand circulation during the sandblasting process and reduces sand accumulation between the product and the fixture.
[0021] Because the product uses a shallow-depth fixing method for the outer frame, the sandblasting consistency of the product's outer frame edge is improved, reducing large areas of discoloration;
[0022] The inner frame fixing method has been changed from fixing the entire edge to fixing the four corner cylinders. The contact area between the cylinders and the product is less than 3mm, which reduces the sand accumulation between the tooling and the product. The reduction in the covering area leads to an increase in the sandblasting area of the inner frame, which better ensures the consistency after sandblasting.
[0023] The four corner positioning posts are made of soft material and run through the entire thickness of the tooling. They provide flexible fixation, are easy to place and remove, and do not damage the product. The through-hole design allows for sandblasting on both sides of the tooling, thus improving the tooling's service life. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0029] like Figure 1 and Figure 2 As shown, the tooling structure for the ring-shaped sandblasting includes a support tooling 1. The support tooling 1 has several sand flow holes 2 distributed in a matrix, which allows the sand to flow away better during the sandblasting process, so as to meet the timely needs of sand recycling in the sandblasting machine and reduce the accumulation of sand between the product 3 and the tooling.
[0030] The upper edge of the sand hole 2 is provided with an upper product outer frame positioning groove 4, and several product inner frame positioning posts 5 are fixedly connected in parallel in the upper product outer frame positioning groove 4.
[0031] The lower edge of the sand flow hole 2 is provided with a positioning groove 7 for the lower product outer frame.
[0032] The lower end of the product inner frame positioning post 5 passes through the lower product outer frame positioning groove 7 and extends downwards.
[0033] An insertion hole is provided between the upper product outer frame positioning groove 4 and the lower product outer frame positioning groove 7, and the product inner frame positioning post 5 is inserted into the insertion hole.
[0034] The product's inner frame positioning column 5 is a flexible column.
[0035] The depth of the upper product outer frame positioning groove 4 and the lower product outer frame positioning groove 7 is 0.1-0.3mm.
[0036] The dimensions of the upper product outer frame positioning groove 4 and the lower product outer frame positioning groove 7 are 0.01-0.03mm larger than the outer frame dimension of product 3.
[0037] The outer frame of the ring-shaped heat spreader is positioned, and the surface of the tooling is recessed by 0.1-0.3mm. The recessed shape differs from the shape and size of product 3 by 0.01-0.03mm. The tooling is fixed by contour positioning, and product 3 is in a fixed state during the sandblasting process, so product 3 will not be damaged during the sandblasting process.
[0038] The sand flow hole 2 is rectangular in shape, and the four corners of the sand flow hole 2 are provided with inwardly protruding support sections 6.
[0039] The product's inner frame positioning posts 5 are four in number, located at the four corners of the sand flow holes 2.
[0040] The working principle of this device is as follows:
[0041] Because the support fixture 1 was changed from a cavity type to a hollow type, it better meets the sand circulation during the sandblasting process and reduces sand accumulation between the product 3 and the fixture.
[0042] Because Product 3 uses a shallow-depth fixing method for the outer frame, the sandblasting consistency of the outer frame edge of Product 3 is improved, reducing large areas of discoloration;
[0043] The inner frame fixing method has been changed from fixing the entire edge to fixing the four corner cylinders. The contact area between the cylinder and product 3 is less than 3mm, which reduces the sand accumulation between the tooling and product 3. The reduction of the covering area leads to an increase in the sandblasting area of the inner frame, which better ensures the consistency after sandblasting.
[0044] The four corner positioning posts are made of soft material and run through the entire thickness of the tooling. They are flexible, easy to place and remove, and do not damage the product. The through-hole design allows sandblasting on all 12 sides of the tooling, improving the tooling's service life.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
