Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for die casting machines, specifically to a sliding plate clamping device. Background Technology

[0002] Mold casting machines, widely used in the mass production of metal components and mechanical parts, occupy an important position in various industrial fields such as automobile manufacturing, construction machinery, and aerospace due to their advantages of compact structure, convenient operation, and high forming accuracy. The core working principle of this type of casting machine is to drive the upper mold downward through a drive mechanism, so that it can precisely close with the fixed lower mold.

[0003] Mold casting machines often require continuous operation for extended periods, with frequent and repetitive mold closing and opening actions. However, during prolonged casting operations, gaps tend to gradually form between the molds, a problem that has become a key bottleneck restricting the quality and production efficiency of cast products. These gaps can trigger a series of serious problems, leading to defects such as insufficient material, flash, and burrs in the castings, significantly reducing the product yield. Subsequent processing requires additional manpower and equipment for trimming and grinding, increasing production steps and costs. Furthermore, the continued widening of the gaps exacerbates mold wear, shortens mold lifespan, and further increases production costs for the company.

[0004] Existing technologies often attempt to delay the formation of gaps by improving the machining accuracy of molds, selecting high-strength wear-resistant materials, or enhancing the installation and debugging accuracy of molds. However, these methods cannot fundamentally solve the problems of mold surface wear and thermal deformation caused by long-term continuous operation, and mold gaps will still inevitably appear. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a sliding plate clamping device that can finely adjust the position of the die-casting machine mold.

[0006] The objective of this utility model is achieved through the following technical measures: A sliding plate clamping device, characterized in that: it includes two side fixing plates, a top mounting plate is fixedly connected to the upper surface of the two side fixing plates, a spring clamping assembly is connected to the top mounting plate, a sliding plate adjusting component is connected to one of the side fixing plates, a lower pressure mold frame is slidably connected between the two side fixing plates, a lower pressure mold mounting block is fixedly connected to the lower pressure mold frame, a mold connecting assembly is connected to the lower pressure mold mounting block, the mold connecting assembly includes a mold connecting slider, a clamping adjusting slope is provided on the upper surface of the mold connecting slider, the mold connecting assembly is connected to the sliding plate adjusting component, the sliding plate adjusting component includes a sliding plate assembly and an adjusting component, the sliding plate assembly includes a clamping sliding plate, a sliding plate slope is provided on the lower surface of the clamping sliding plate, and the sliding plate slope is configured to cooperate with the clamping adjusting slope.

[0007] As an improvement: the adjustment assembly includes an adjustment housing, a gear reducer is disposed inside the adjustment housing, the gear reducer is fixedly connected to the side of the side fixing plate, a drive screw is fixedly connected to the input end of the gear reducer, and a hand-cranked connecting flange is fixedly connected to the drive screw.

[0008] As an improvement: the slide assembly includes an adjusting screw, one end of which is connected to the output end of a gear reducer, and the adjusting screw tube passes through a side fixing plate.

[0009] As an improvement: the spring clamping assembly includes a spring protective cover, which is fixedly connected to the top mounting plate. Four limiting screws are sleeved inside the spring protective cover, and each of the four limiting screws is fitted with a clamping spring. The four limiting screws pass through the top mounting plate and the clamping slide plate and are connected to the mold connecting slider.

[0010] As an improvement: each of the four limiting screws is fitted with a limiting stop plate for limiting the clamping spring, and the ends of the four limiting screws are threaded with limiting bolts for limiting the displacement of the limiting stop plates. One end of the clamping spring is in contact with the top mounting plate, and the other end of the clamping spring is in contact with the limiting stop plate.

[0011] As an improvement: the mold connecting assembly includes a mold limiting shaft, which passes through the mold connecting slider. A limiting shaft end slider is fixedly connected to the end of the mold limiting shaft. End slider limiting grooves are provided on both side fixing plates. The limiting shaft end slider is slidably connected to the end slider limiting groove.

[0012] As an improvement: one end of the mold limiting shaft is rotatably connected to the mold connecting block, and the other end of the mold connecting block is rotatably connected to the pressing mold mounting block, and the pressing mold mounting block is slidably connected to the pressing mold frame.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: This device utilizes the sliding plate ramp of the sliding plate adjustment component to engage with the clamping adjustment ramp of the mold connecting assembly. A drive screw drives a gear reducer, which in turn rotates the adjustment screw, thus moving the clamping sliding plate. The sliding engagement between the sliding plate ramp and the clamping adjustment ramp enables smooth lifting and lateral clamping of the mold connecting slider. The entire adjustment process is continuous and labor-saving, eliminating the need for repeated disassembly of components. Clamping force and stroke can be precisely controlled simply by rotating the hand-cranked connecting flange, extending mold life and reducing production costs. Because frequent adjustments are unnecessary, the hand-cranked connecting flange with a hand crank handle provides a compact structure and convenient maintenance, requiring no specialized training. Furthermore, the hand-cranked drive screw controls the clamping degree, preventing excessive tightening and accelerated wear. The gear reducer provides deceleration, allowing for precise control of the clamping force and avoiding damage to the workpiece or mold due to excessive clamping. Attached Figure Description

Detailed Implementation

[0019] Example: Figures 1 to 4As shown, a sliding plate clamping device includes two side fixing plates 1, a top mounting plate 2 fixedly connected to the upper surface of the two side fixing plates 1, a spring clamping assembly 3 connected to the top mounting plate 2, a sliding plate adjusting component 4 connected to one of the side fixing plates, a downward pressing mold frame 5 slidably connected between the two side fixing plates 1, a downward pressing mold mounting block 7 fixedly connected to the downward pressing mold frame 5, a mold connecting assembly 6 connected to the downward pressing mold mounting block 7, the mold connecting assembly 6 including a mold connecting slider 61, a clamping adjusting inclined surface 62 provided on the upper surface of the mold connecting slider 61, the mold connecting assembly 6 cooperating with the sliding plate adjusting component 4, the sliding plate adjusting component 4 including a sliding plate assembly 41 and an adjusting component 42, the sliding plate assembly 41 including a clamping sliding plate 411, a sliding plate inclined surface 412 provided on the lower surface of the clamping sliding plate 411, the sliding plate inclined surface 412 cooperating with the clamping adjusting inclined surface 62.

[0020] The adjustment assembly 42 includes an adjustment housing 421, within which a gear reducer 422 is disposed. The gear reducer 422 is fixedly connected to the side of the side fixing plate 1. A drive screw 423 is fixedly connected to the input end of the gear reducer 422, and a hand crank connecting flange 424 is fixedly connected to the drive screw 423. The hand crank connecting flange 424 facilitates the connection of a hand crank, which, by rotating, drives the drive screw 423. This, in turn, is decelerated by the gear reducer 422 and drives the adjustment screw 413, thereby achieving the forward and backward movement of the clamping slide plate 411.

[0021] The slide assembly 41 includes an adjusting screw 413, one end of which is connected to the output end of a gear reducer 422. The adjusting screw 413 passes through a side fixing plate 1. The operator rotates the hand crank connecting flange 424 via a hand crank, causing the drive screw 423 to rotate. The drive screw 423 transmits power to the gear reducer 422. After reduction and torque amplification, the output end of the gear reducer 422 drives the adjusting screw 413 to rotate. Because of the sliding plate inclined surface 412 and the clamping adjusting inclined surface 62, when the sliding plate inclined surface 412 moves to one side, it pushes the clamping adjusting inclined surface 62, generating a downward pressure under the action of the inclined surface, thereby adjusting the vertical position of the mold connecting slider 61.

[0022] The spring clamping assembly 3 includes a spring protective cover 31, which is fixedly connected to the top mounting plate 2. Four limiting screws 32 are sleeved inside the spring protective cover 31, and each of the four limiting screws 32 is fitted with a clamping spring 33. The four limiting screws 32 pass through the top mounting plate 2 and the clamping slide plate 411 and are connected to the mold connecting slider 61. During clamping, the clamping spring 33 at the top is compressed by the pressure of the limiting baffle 34, generating an upward elastic reaction force. This reaction force is transmitted through the limiting screws 32, making the clamping inclined surfaces fit more tightly and improving clamping reliability.

[0023] Each of the four limiting screws 32 is fitted with a limiting baffle 34 for limiting the tensioning spring 33. The ends of the four limiting screws 32 are threaded with limiting bolts 35 for limiting the displacement of the limiting baffles 34. One end of the tensioning spring 33 is in contact with the top mounting plate 2, and the other end of the tensioning spring 33 is in contact with the limiting baffle 34.

[0024] The mold connecting assembly 6 includes a mold limiting shaft 63, which passes through the mold connecting slider 61. A limiting shaft end slider 65 is fixedly connected to the end of the mold limiting shaft 63. End slider limiting grooves 66 are provided on both side fixing plates 1, and the limiting shaft end slider 65 is slidably connected to the end slider limiting grooves 66. The end slider limiting grooves 66 can restrict the movement of the limiting shaft end slider 65, thereby limiting the movement trajectory of the mold connecting slider 61 through the mold limiting shaft 63, preventing the mold connecting slider 61 from deviating from the trajectory and causing the mold to fail to complete the pressing process.

[0025] The mold limiting shaft 63 is rotatably connected to one end of the mold connecting block 64, and the other end of the mold connecting block 64 is rotatably connected to the pressing mold mounting block 7. The pressing mold mounting block 7 is slidably connected to the pressing mold frame 5. The mold limiting shaft 63 can drive the mold connecting block 64, thereby enabling the mold connecting assembly 6 to drive the pressing mold mounting block 7 to move downward, thereby reducing the mold gap without affecting the normal use of the pressing mold mounting block 7.
