Description

Technical Field

[0001] The utility model relates to the technical field of die casting tooling, in particular to a die casting tooling fixture. Background Art

[0002] In the manufacturing process of die-casting parts, after die-casting, they need to be subjected to secondary processing such as workpiece assembly to become qualified die-casting parts that meet the use requirements. Usually, when assembling some workpieces that need to be inserted on the die-casting workpiece, the inserted workpieces that need to be inserted into the die-casting workpiece are knocked in by hand-held tools. However, hand-held processing is prone to fatigue, resulting in low processing efficiency, and hand-held workpieces are prone to injury.

[0003] A Chinese patent with announcement number CN217315441U discloses a die casting fixture, including a lower die base, a hydraulic telescopic rod, and an upper die base fixed to the end of the hydraulic telescopic rod by bolts, and a mounting frame is fixed to the top outer side of the upper die base by bolts.

[0004] Although the die-casting fixture described in the above patent solves the shortcomings of the existing die-casting fixtures that are inconvenient to use and have low hand-held processing efficiency, the die-casting fixture of the above structure needs to be manually adjusted twice before press-fitting the die-casting to make the clamp contact with the side wall of the die-casting. The whole adjustment process is relatively cumbersome, which makes the clamping and fixing efficiency of the die-casting before press-fitting relatively low, making it inconvenient to perform efficient press-fitting processing on the die-casting. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The technical problem to be solved by the utility model is to provide a die casting fixture which can realize fast clamping of the die casting by means of the deadweight of the die casting while placing the die casting in view of the current status of the prior art.

[0007] (II) Technical solution

[0009] Furthermore, the linkage rod passes through the bottom end of the mounting groove and is slidably connected to the mounting groove, the top end of the spring is welded to the placement plate, and the bottom end of the spring is welded to the bottom end of the mounting groove.

[0010] By adopting the above technical solution, the spring can realize the automatic rebound of the placement plate when the die-casting is taken out after being pressed. When the placement plate rebounds, it will drive the linkage plate to move up with the help of the linkage rod, so that the sliding rod and the clamping plate can be pulled back under the action of the connecting rod, thereby realizing the separation of the clamping plate and the die-casting.

[0011] Furthermore, the bottom end of the connecting rod is hinged to the linkage plate, and the top end of the connecting rod is hinged to the corresponding sliding rod.

[0012] By adopting the above technical solution, it is possible to ensure that the connecting rod can rotate conveniently relative to the sliding rod and the linkage plate.

[0013] Furthermore, the sliding sleeve is bolted to the top end of the installation cavity, and the sliding rod is slidably connected to the sliding sleeve.

[0014] By adopting the above technical solution, the sliding sleeve can ensure that the sliding rod slides stably.

[0015] Furthermore, the installation groove is provided with a hollow structure at a position opposite to the clamping plate, and the sliding rod is connected with the clamping plate bolts.

[0016] By adopting the above technical solution, the clamping plate can be conveniently retracted into the installation cavity when not clamped.

[0017] Furthermore, a pressing mechanism is installed on one side of the upper end of the base, and the pressing mechanism includes an inverted L-shaped mounting frame welded on one side of the upper end of the base, a hydraulic telescopic rod installed in the middle of the upper end of the mounting frame, and a pressing platform installed on the telescopic part of the hydraulic telescopic rod.

[0018] By adopting the above technical solution, the hydraulic telescopic rod drives the press table to move downward, so that automatic press-fitting between die-cast parts can be achieved.

[0019] Furthermore, the fixing portion of the hydraulic telescopic rod is bolted to the mounting frame, and the telescopic portion of the hydraulic telescopic rod passes through the top of the mounting frame and is bolted to the press table.

[0020] By adopting the above technical solution, it can be ensured that the press table moves synchronously with the telescopic part of the hydraulic telescopic rod.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] In order to solve the problem that the existing die-casting tooling fixture solves the inconvenience of using the existing die-casting tooling fixture and the low efficiency of hand-held processing, the die-casting tooling fixture of the above structure needs to be manually adjusted twice before the die-casting is pressed, so that the clamping plate contacts the side wall of the die-casting, and the whole adjustment process is relatively cumbersome, so that the clamping and fixing efficiency of the die-casting before press-fitting is relatively low, and it is not convenient to perform efficient press-fitting processing on the die-casting. The structure can use the weight of the die-casting to move the placement plate downward after the die-casting is placed on the placement plate in the linkage clamping mechanism, so that in the process of moving the placement plate downward, the clamping plate can be automatically clamped to the side wall of the die-casting with the help of connecting rods, sliding rods and sliding sleeves, and the clamping plate can be automatically reset by the action of the spring when the die-casting is taken out after press-fitting. Since this clamping method eliminates the tedious manual adjustment of the clamping, the clamping efficiency of the die-casting before press-fitting is higher, which facilitates efficient press-fitting of the die-casting.

When the placement plate 203 rebounds, it will drive the linkage plate 206 to move up with the help of the linkage rod 208, so that the sliding rod 202 and the clamping plate 207 can be pulled back under the action of the connecting rod 204, thereby realizing the separation of the clamping plate 207 from the die-casting. The installation groove 4 is a hollow structure facing the clamping plate 207, and the sliding rod 202 is bolted to the clamping plate 207, so that the clamping plate 207 can be easily retracted into the installation cavity 5 when not clamped.

[0031] like Figure 1-Figure 3 As shown, in this embodiment, the linkage rod 208 passes through the bottom end of the mounting groove 4 and is slidably connected to the mounting groove 4, the top end of the spring 205 is welded to the placement plate 203, the bottom end of the spring 205 is welded to the bottom end of the mounting groove 4, the bottom end of the connecting rod 204 is hinged to the linkage plate 206, and the top end of the connecting rod 204 is hinged to the corresponding sliding rod 202, which can ensure the convenient rotation of the connecting rod 204 relative to the sliding rod 202 and the linkage plate 206, the sliding sleeve 201 is bolted to the top end of the mounting cavity 5, the sliding rod 202 is slidably connected to the sliding sleeve 201, and the sliding sleeve 201 can ensure the stable sliding of the sliding rod 202.

[0032] like Figure 1 As shown, in this embodiment, a press-fitting mechanism 1 is also installed on one side of the upper end of the base 3. The press-fitting mechanism 1 includes an inverted L-shaped mounting frame 103 welded to one side of the upper end of the base 3, a hydraulic telescopic rod 101 installed in the middle of the upper end of the mounting frame 103, and a press table 102 installed on the telescopic part of the hydraulic telescopic rod 101.

Since this clamping method eliminates the tedious manual adjustment of the clamping, the clamping efficiency of the die-casting before the press-fitting process is higher, which facilitates the efficient press-fitting of the die-casting.
