Description

Technical Field

[0001] This utility model relates to the field of mold crushing technology, and in particular to a crushing device for casting sand molds of automotive parts. Background Technology

[0002] In the automotive parts casting process, because the castings are completely encased in the sand mold and sand core after cooling and forming, the sand mold must be broken in order to remove the castings completely and clean the internal channels. However, traditional sand molds mostly rely on workers to manually strike them with hammers. Due to the uneven thickness and strength of the sand molds, it is difficult to accurately control the striking force, which can easily lead to surface damage, cracks, or burrs on the castings. In addition, the sand core residue is not thoroughly cleaned. Furthermore, the manual operation is labor-intensive and the crushing speed is slow, resulting in low production efficiency and poor product consistency. This seriously restricts the demand for high-precision mass production of complex parts such as automobile engine blocks and gearbox housings. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a crushing device for casting sand molds of automotive parts, including a support frame and a motor, the motor being fixedly installed on one side of the support frame; a crushing hopper, the crushing hopper being fixedly installed on the support frame; a conical disc, the conical disc being rotatably installed inside the crushing hopper and driven by the motor to rotate; and a blade, the blade being fixed on the upper part of the conical disc, the blade cooperating with the conical disc to perform a rapid mold crushing action when the conical disc rotates.

[0005] In at least some embodiments, the blades are provided in multiples, and the multiple blades are circumferentially arrayed and fixedly mounted on the upper part of the conical disk.

[0006] In at least some embodiments, a protective pad is fixedly installed on the upper part of the blade plate to protect the cast automotive parts, and a discharge gap is formed between the cone disc and the inner wall of the crushing tank to guide and collect the crushed mold shell.

[0007] In at least some embodiments, the lower part of the support frame is fixedly connected to a housing, the motor output end is fixedly connected to a first rotating wheel rotatably installed inside the housing, and a second rotating wheel rotatably installed inside the housing is driven by the first rotating wheel through a transmission belt.

[0008] In at least some embodiments, a sleeve is inserted into the upper part of the square rod fixed to the upper part of the second rotating wheel. The upper turntable fixed to the lower part of the sleeve and the lower turntable fixed to the upper part of the machine housing rotate and fit together, and the fitting part is formed with an inclined gap. When the square rod rotates, it drives the cone plate fixed to the upper part of the sleeve to move up and down and rotate, so as to realize the rapid mold breaking action. The machine housing is used for dust prevention of the first and second rotating wheels.

[0009] In at least some embodiments, the crushing tank includes a fixed tube fixed to the support frame, and a lifting tube is slidably installed on the upper part of the fixed tube via a screw, and the vertical position adjustment of the lifting tube is achieved by rotating the screw.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a motor drives a conical disc to rotate, which in turn drives a blade plate fixed on its upper part to rotate at high speed. When the waste sand mold is put into the crushing tank, the sand mold and the blade plate generate strong cutting and impact forces. Under the action of high-speed shearing force and friction, the sand mold structure is quickly broken into small particles, thereby realizing the rapid disintegration of the whole sand mold.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Example, according to Figures 1-4 As shown in the figure, the present invention provides a crushing device for casting sand molds of automotive parts, including a support frame 1, a motor 2, the motor 2 being fixedly installed on one side of the support frame 1; a crushing tank 3, the crushing tank 3 being fixedly installed on the support frame 1; a conical disc 4, the conical disc 4 being rotatably installed inside the crushing tank 3 being driven by the motor 2 to rotate; and a blade 5, the blade 5 being fixed on the upper part of the conical disc 4, the blade 5 cooperating with the conical disc 4 to perform a rapid mold crushing action when the conical disc 4 rotates.

[0016] The aforementioned crushing device for casting sand molds of automotive parts drives the conical disc 4 to rotate via the motor 2, which in turn drives the fixed blade 5 on its upper part to rotate at high speed. When the waste sand mold is put into the crushing tank 3, the sand mold and the blade 5 generate strong cutting and impact forces. Under the action of high-speed shearing force and friction, the sand mold structure is quickly crushed into small particles, thereby realizing the rapid disintegration of the entire sand mold. At the same time, the rotation of the conical disc 4 can also generate centrifugal dispersion force, so that the crushed sand particles are evenly scattered at the bottom of the crushing tank 3, which is convenient for subsequent centralized collection and recycling.

[0017] In this embodiment, multiple blades 5 are provided, and multiple blades 5 are circumferentially arrayed and fixedly installed on the upper part of the cone disk 4. A protective pad 15 is fixedly installed on the upper part of the blades 5. The protective pad 15 is used to protect the cast automotive parts. A feeding gap 14 is formed between the cone disk 4 and the inner wall of the crushing tank 3 to guide and collect the crushed mold shell.

[0018] Motor 2 drives cone disk 4 to rotate. Multiple blades 5 arranged in a circumferential array on the upper part of cone disk 4 rotate at high speed and come into contact with sand mold to generate cutting and impact forces, thereby quickly crushing the outer shell of sand mold. The protective pads 15 set above the blades 5 protect the cast automotive parts during the crushing process, avoiding damage caused by direct contact with the blades 5. At the same time, the material discharge gap 14 formed between cone disk 4 and the inner wall of crushing tank 3 can guide and collect the crushed sand particles during the sand mold crushing process, ensuring that the sand falls smoothly into the bottom of crushing tank 3 for centralized cleaning and recycling, thereby achieving efficient crushing of casting sand mold and safe removal of castings.

[0019] In this embodiment, the lower part of the support frame 1 is fixedly connected to the housing 6. The output end of the motor 2 is fixedly connected to the first rotating wheel 7 rotatably installed inside the housing 6. The second rotating wheel 9 rotatably installed inside the housing 6 is driven by the first rotating wheel 7 through the transmission belt 8. A sleeve 11 is inserted and installed on the upper part of the square rod 10 fixed on the upper part of the second rotating wheel 9. The upper turntable 12 fixed on the lower part of the sleeve 11 and the lower turntable 13 fixed on the upper part of the housing 6 rotate and fit together, and the fitting part is formed with an inclined gap. When the square rod 10 rotates, it drives the cone plate 4 fixed on the upper part of the sleeve 11 to move up and down and rotate, so as to realize the rapid crushing action. The housing 6 is used for the dustproof action of the first rotating wheel 7 and the second rotating wheel 9. The crushing tank 3 includes a fixed tube 301 fixed on the support frame 1. A lifting tube 302 is slidably installed on the upper part of the fixed tube 301 through the screw 303. Rotating the screw 303 realizes the up and down position adjustment action of the lifting tube 302.

[0020] The motor 2 is fixedly installed on one side of the support frame 1, and its output end is fixedly connected to the first rotating wheel 7 installed inside the housing 6. The first rotating wheel 7 drives the second rotating wheel 9, which meshes with it through the transmission belt 8, to rotate synchronously. The rotation of the second rotating wheel 9 further drives the square rod 10 fixed on its upper part to rotate. The sleeve 11 installed on the upper part of the square rod 10 is driven when the square rod 10 rotates, thereby driving the upper turntable 12 fixed on the lower part of the sleeve 11 to rotate and form a close running state with the lower turntable 13. The contact point between the upper and lower turntables 13 is specially formed with an inclined gap. When the square rod 10 continues to rotate, the inclined guide effect generated by the inclined gap causes the upper turntable 12 to move up and down while maintaining rotation. This enables the sleeve 11 and the cone 4 fixed on its upper part to both rotate continuously and perform a combined up and down movement, thereby driving the blade 5 fixed on the upper part of the cone 4 to complete a high-speed cutting, impact and up and down impact combined action, and to perform all-round rapid crushing of the casting sand mold put into the crushing tank 3.

[0021] At the same time, the protective pad 15 fixed on the upper part of the blade 5 can effectively isolate the direct impact between the blade 5 and the casting, ensuring that the automotive parts are not damaged during the crushing process.

[0022] The housing 6 structure is used to provide dustproof sealing protection for the first rotor 7 and the second rotor 9, so as to prevent dust from entering the transmission mechanism and affecting the operational stability.

[0023] The crushing hopper 3 adopts a sliding structure design with a fixed pipe 301 and a lifting pipe 302. The lifting pipe 302 can be adjusted by the screw 303 to flexibly change its up and down position, so that the size of the feeding channel and the crushing space can be flexibly adapted to sand molds of different specifications. This ensures that the crushed sand particles can pass smoothly through the feeding gap 14 between the cone plate 4 and the inner wall of the crushing hopper 3 and be guided to the bottom for centralized cleaning and recycling.

[0024] Through the above combination, this embodiment not only achieves high-speed rotational crushing of the cone disk 4, but also introduces an up-and-down lifting auxiliary impact function, which makes the crushing effect more complete and avoids the problem of local sand molds being difficult to crush. Furthermore, the adjustable lifting tube 302 design enables adaptability to sand molds of different sizes, greatly improving crushing efficiency, stability and casting removal safety.

[0025] The working principle of this utility model is as follows: the motor 2 drives the cone disk 4 to rotate, which in turn drives the blade plate 5 fixed on its upper part to rotate at high speed. When the waste sand mold is put into the crushing tank 3, the sand mold and the blade plate 5 generate strong cutting and impact. Under the action of high-speed shearing force and friction, the sand mold structure is quickly broken into small particles, thereby realizing the rapid disintegration of the whole sand mold. At the same time, the rotation of the cone disk 4 can also generate centrifugal dispersion force, so that the crushed sand particles are evenly scattered at the bottom of the crushing tank 3, which is convenient for subsequent centralized collection and recycling.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
