Description

Technical Field

[0001] This utility model relates to an injection mold inspection fixture, belonging to the field of inspection fixture technology. Background Technology

[0002] Injection molds are tools used to produce plastic products. They are devices that inject resin material into a metal mold to obtain a product with a certain shape. The product dimensions must be checked before the product leaves the factory.

[0003] Chinese Patent Publication No. CN 220160548 U discloses a fixture for detecting the dimensions of injection molded products. The fixture includes a base plate, with telescopic rods fixedly connected to the left and right sides of the top center of the base plate. The output ends of the telescopic rods on the same side are fixedly connected to the left and right sides of the bottom center of a connecting plate near the edge. A groove is provided in the center of the bottom center of the connecting plate, and a slider is slidably connected to the center of the groove. A connecting rod is fixedly connected to the center of the bottom center of the slider, and a threaded rod is threadedly connected to the center of the connecting rod. In this invention, the product is placed in the detection groove, and the motor, in conjunction with the threaded rod, slider, and groove, causes a scraper to move. Products on top of the second filter plate meet the requirements, eliminating the need for manual measurement. Furthermore, the product is first removed from the collection groove, the second filter plate is removed, and the product falls into the collection groove for collection. Similarly, products on top of the first filter plate are collected, reducing labor costs.

[0004] The testing fixture is quite heavy, and adjusting its position is often costly. When it is equipped with casters at the bottom, the equipment may shake due to accidental collisions from external factors. Even with casters that have a self-locking effect, the circular shape of the casters results in a small contact area with the ground, which may still cause the entire equipment to shake due to external interference, thus affecting the accuracy of mold testing.

[0005] To address this, a testing fixture for injection molds is proposed. Utility Model Content

[0006] In view of this, the present invention provides an injection mold inspection fixture to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: an injection mold testing fixture includes a box body, a mounting plate is snapped onto the top of the box body, a fixture body is fixedly mounted on the top of the mounting plate, a support mechanism is provided on the surface of the box body, the support mechanism includes a motor, connecting rods and lead screws, the motor is fixedly mounted on the surface of the inner cavity of the box body, four connecting rods are movably connected to the front and rear sides of the inner cavity surface of the box body, four lead screws are located on the left and right sides of the inner cavity of the box body, screw blocks are threaded onto the surface of the four lead screws, lifting blocks are fixedly mounted on the outer side of the four screw blocks, support rods are fixedly mounted on the bottom of the four lifting blocks, support plates are fixedly mounted on the bottom of the four support rods, and casters are movably connected to all four sides of the bottom of the box body.

[0008] More preferably, each of the four connecting rods is fixedly connected to an active bevel gear on its outer side, and each of the four inner cavities of the housing is movably connected to a driven bevel gear on its four sides. The surfaces of the four active bevel gears mesh with the surfaces of the four driven bevel gears, and the four lead screws are fixedly connected to the bottom of the four driven bevel gears.

[0009] More preferably, the output end of the motor is fixedly connected to an active synchronous shaft, the left side of the inner cavity of the housing is movably connected to a driven synchronous shaft, the surfaces of the active and driven synchronous shafts are movably connected to a driven synchronous belt, the right side of the inner cavity of the housing is movably connected to a secondary synchronous shaft, the surfaces of the active and secondary synchronous shafts are movably connected to a secondary synchronous belt, and the four connecting rods are all fixedly installed on the front and rear sides of the secondary and driven synchronous shafts.

[0010] More preferably, the surfaces of the four connecting rods are movably connected to support blocks via bearings, and the four support blocks are fixedly installed around the top of the inner cavity of the box.

[0011] More preferably, the left and right sides of the inner cavity of the box are provided with moving slots, and the outer sides of the four lifting blocks are slidably connected to the inner cavities of the four moving slots.

[0014] More preferably, a storage bag is provided on the left side of the box, and the storage bag is connected to the left side of the box by bolt thread.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model, by setting up a support mechanism, allows the casters to move the entire equipment, improving the ease of adjusting the overall position of the equipment. When it is necessary to stabilize the overall position of the equipment, the output of the motor causes the active bevel gear to drive the lead screw to rotate. At this time, the support rod moves downward, causing the support plate to move, thus releasing the casters from contact with the ground and completing the work of supporting and stabilizing the overall equipment. This effectively avoids the equipment from moving due to accidental external collisions when the mounting plate is inspecting the mold, thereby affecting the accuracy of mold inspection.

[0017] II. This utility model, by setting a support block, can support the connecting rod, preventing the connecting rod from falling off due to the weight of the active bevel gear after prolonged use. By setting a moving groove, the lifting block can be limited, preventing it from shifting during movement and affecting the overall stability of the equipment. By setting a limiting rod, the movement of the screw block can be limited, preventing it from rotating synchronously with the lead screw, which would also affect the overall stability of the equipment. By setting an anti-slip pad, the friction between the support plate and the ground can be increased due to the properties of the anti-slip pad material, thereby improving the overall stability of the equipment. By setting a storage bag, smaller parts can be conveniently stored, preventing them from being lost.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 2-5As shown, this utility model embodiment provides an injection mold testing fixture, including a housing 1. A mounting plate 3 is snapped onto the top of the housing 1, and a fixture body 4 is fixedly mounted on the top of the mounting plate 3. A support mechanism 2 is provided on the surface of the housing 1. The support mechanism 2 includes a motor 201, connecting rods 207, and lead screws 210. The motor 201 is fixedly mounted on the surface of the inner cavity of the housing 1. The four connecting rods 207 are movably connected to the front and rear sides of the inner cavity surface of the housing 1. The four lead screws 210 are located on the left and right sides of the inner cavity of the housing 1. Screw blocks 211 are threaded onto the surface of each of the four lead screws 210. Lifting blocks 212 are fixedly mounted on the outer sides of each of the four screw blocks 211. Support rods 213 are fixedly mounted on the bottom of each of the four lifting blocks 212. Support plates 214 are fixedly mounted on the bottom of each of the four support rods 213. Universal wheels 215 are movably connected to all four sides of the bottom of the housing 1. The outer sides of the four connecting rods 207 are all fixedly connected to the driving bevel gears 208. The top of the inner cavity of the housing 1 is movably connected to the driven bevel gears 209. The surfaces of the four driving bevel gears 208 mesh with the surfaces of the four driven bevel gears 209. The four lead screws 210 are all fixedly connected to the bottom of the four driven bevel gears 209. The output end of the motor 201 is fixedly connected to the driving synchronous shaft 202. The left side of the inner cavity of the housing 1 is movably connected to the driven synchronous shaft 203. The surfaces of the driving synchronous shaft 202 and the driven synchronous shaft 203 are movably connected to the driven synchronous belt 204. The right side of the inner cavity of the housing 1 is movably connected to the auxiliary synchronous shaft 205. The surfaces of the driving synchronous shaft 202 and the auxiliary synchronous shaft 205 are movably connected to the auxiliary synchronous belt 206. The four connecting rods 207 are all fixedly installed on the front and rear sides of the auxiliary synchronous shaft 205 and the driven synchronous shaft 203.

[0030] By setting up support mechanism 2, the caster wheel 215 can move the entire equipment by pushing it, improving the convenience of adjusting the overall position of the equipment. When it is necessary to stabilize the overall position of the equipment, the output of motor 201 causes the active bevel gear 208 to drive the lead screw 210 to rotate. At this time, the support rod 213 moves the support plate 214 downward, causing the caster wheel 215 to release its contact with the ground, thus completing the work of supporting and stabilizing the overall equipment. This effectively prevents the equipment from moving due to accidental external collisions when the mounting plate 3 is inspecting the mold, thereby affecting the accuracy of mold inspection.

[0031] Example 2

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, in one embodiment, the surfaces of the four connecting rods 207 are movably connected to support blocks 219 via bearings. The four support blocks 219 are fixedly installed around the top of the inner cavity of the box 1. Movable grooves 217 are provided on both the left and right sides of the inner cavity of the box 1. The outer sides of the four lifting blocks 212 are slidably connected to the inner cavities of the four movable grooves 217. Limiting rods 218 are fixedly installed around the inner cavity of the box 1. The four screw blocks 211 are slidably connected to the surfaces of the four limiting rods 218. Anti-slip pads 216 are fixedly installed at the bottom of the two support plates 214. The anti-slip pads 216 are made of rubber. A storage bag 5 is provided on the left side of the box 1. The storage bag 5 is connected to the left side of the box 1 by bolt threads.

[0033] By setting the support block 219, the connecting rod 207 can be supported, preventing the connecting rod 207 from falling off due to the weight of the active bevel gear 208 after long-term use. By setting the moving groove 217, the lifting block 212 can be limited, preventing the lifting block 212 from deviating during movement, thus affecting the overall stability of the equipment. By setting the limit rod 218, the movement of the screw block 211 can be limited, preventing the screw block 211 from rotating synchronously with the lead screw 210, thus affecting the overall stability of the equipment. By setting the anti-slip pad 216, the friction between the support plate 214 and the ground can be increased due to the characteristics of the anti-slip pad 216 material, thereby improving the overall stability of the equipment. By setting the storage bag 5, smaller parts can be conveniently stored, preventing the parts from being lost.

[0034] In operation, when the equipment needs to be moved, the operator pushes the casters 215 to rotate. After the equipment is moved to the desired position, the output of the motor 201 causes the active synchronous shaft 202 to rotate. The active synchronous shaft 202, in conjunction with the auxiliary synchronous belt 206 and the driven synchronous belt 204, causes the auxiliary synchronous shaft 205 and the driven synchronous shaft 203 to rotate. At this time, the connecting rod 207 drives the active bevel gear 208 to rotate, and causes the driven bevel gear 209 to rotate synchronously. The lead screw 210 rotates, causing the screw block 211 to drive the lifting block 212 to move downward. At this time, the support rod 213 and the support plate 214 follow the lifting block 212 to move downward. The support plate 214 contacts the ground, and the casters 215 release from contact with the ground, thus completing the work of supporting and stabilizing the equipment.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
