Description

Technical Field

[0001] The utility model relates to the technical field of encoder production, in particular to a precision temperature-controlled encoder main body precision casting machine. Background Technique

[0002] An encoder is a device that compiles and converts signals or data into signal forms that can be used for communication, transmission, and storage. During the processing and production of an encoder, various precision parts need to be installed inside the housing main body of the encoder. The housing main body belongs to a type of mechanical structure and needs to be produced using a precision casting machine and a mold.

[0003] For the existing precision temperature-controlled encoder main body precision casting machine, when demolding the formed housing, it is necessary to wait for cooling and then manually demold it. The demolding efficiency is low, and there is a certain danger, which is likely to cause scalding to personnel and is not conducive to use.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a precision temperature-controlled encoder main body precision casting machine is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a precision temperature-controlled encoder main body precision casting machine to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A precision temperature-controlled encoder main body precision casting machine, including a casting mold base, six forming cavities are evenly distributed and opened on the front side of the upper surface of the casting mold base. Sliding grooves are opened on both the left and right sides of the inner surface of the forming cavity. A support slider is slidably arranged inside the sliding groove. A sealing plate is fixedly installed at the upper end of the support slider. An air pump is fixedly installed on the right side of the outer surface of the casting mold base. Air pipes are connected to both the front and rear sides of the air pump. The air pipes penetrate through the casting mold base and extend into each forming cavity. Air nozzles are fixedly installed on the upper surface of the air pipes inside the forming cavity.

[0007] Preferably, the shape of the support slider is "L" shaped. The horizontal short side of the "L" shape of the support slider is located inside the sliding groove, and the vertical rod body is located inside the forming cavity and is connected to the sealing plate.

[0008] Preferably, the sealing plate is in sliding fit with the inner surface of the forming cavity, and the sealing plate serves as the bottom plate of the forming cavity.

[0009] Preferably, a support frame is fixedly installed on the rear side of the upper surface of the casting mold base, and a cross plate is fixedly installed at the upper end of the support frame.

[0010] Preferably, a hydraulic cylinder is fixedly installed on the front side of the upper surface of the cross plate, and a movable plate is fixedly installed at the bottom end of the hydraulic cylinder through the cross plate.

[0011] Preferably, six die-casting molds corresponding to the forming cavities are fixedly installed on the lower surface of the movable plate in a uniformly distributed manner, and a sealing ring is fixedly installed on the movable plate in a manner that fits the upper surface of the die-casting mold.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the settings of the chute, support slider, sealing plate, air pump, air pipe and air nozzle, under normal conditions, the sealing plate is located below the inner part of the forming cavity under the action of its own gravity and is used as the bottom plate. During the casting process, the support slider supports the sealing plate using the bottom end of the chute. After the encoder housing is formed, the air pump sucks in external air, transports it through the air pipe, and then sprays it out through each air nozzle. Under the action of the air flow, the sealing plate moves upward, thereby pushing out the housing for rapid demoulding work. And along with the flow of the air, it can also cool the formed housing, greatly improving the efficiency and convenience of demoulding and taking parts, and enabling the housing to be quickly cooled and shaped. Moreover, in the above solution, the air flow and air pressure are used for pushing, which can ensure that the force under the sealing plate is uniform, so that the driving force is more uniform and comprehensive, preventing tilting and jamming.

[0014] 2. Through the settings of the forming cavity, die-casting mold and sealing ring, six forming cavities correspond to six die-casting molds, and multiple encoder housing bodies can be produced at one time, greatly improving the working production efficiency. At the same time, during the production process, after the die-casting mold is inserted into the inner part of the forming cavity, the sealing ring tightly seals the periphery of the upper opening of the forming cavity, avoiding the extrusion, splashing and leakage of materials, so as to ensure the quality of each formed encoder housing body.

A sealing plate 5 is fixedly installed at the upper end of the support slider 4. An air pump 6 is fixedly installed on the right side of the outer surface of the casting mold base 1. Air pipes 7 are connected to both the front and rear sides of the air pump 6. The air pipes 7 penetrate through the casting mold base 1 and extend into each forming cavity 2. Air nozzles 8 are fixedly installed on the upper surface of the air pipes 7 inside the forming cavity 2.

[0021] Furthermore, the shape of the support slider 4 is set as an "L" shape. The horizontal short side of the "L" shape of the support slider 4 is located inside the slide groove 3, and the vertical rod body is located inside the forming cavity 2 and is connected to the sealing plate 5.

[0022] Furthermore, the sealing plate 5 fits and slides on the inner surface of the forming cavity 2, and the sealing plate 5 serves as the bottom plate of the forming cavity 2.

[0023] By adopting the above technical solutions, the sealing plate 5 is located below inside the forming cavity 2 under the action of its own gravity and serves as the bottom plate; the support slider 4 supports the sealing plate 5 by the bottom end of the slide groove 3; the air pump 6 sucks in external air, transports it through the air pipe 7, and then sprays it out through each air nozzle 8. Under the action of the air flow, the sealing plate 5 moves upward, thereby pushing out the housing for rapid demolding work.

[0024] Furthermore, a support frame 9 is fixedly installed on the rear side of the upper surface of the casting mold base 1, and a cross plate 10 is fixedly installed at the upper end of the support frame 9.

[0025] By adopting the above technical solutions, the support frame 9 and the cross plate 10 support the die-casting part.

[0026] Furthermore, a hydraulic cylinder 11 is fixedly installed on the front side of the upper surface of the cross plate 10, and a movable plate 12 is fixedly installed at the bottom end of the hydraulic cylinder 11 passing through the cross plate 10.

[0027] By adopting the above technical solutions, the hydraulic cylinder 11 can push and pull the movable plate 12 to move up and down.

[0028] Further, six die-casting molds 13 corresponding to the forming cavities 2 are fixedly installed on the lower surface of the movable plate 12 in a uniformly distributed manner, and a sealing ring 14 is fixedly installed on the movable plate 12 in a manner that fits the surface above the die-casting mold 13.

[0029] By adopting the above technical solution, six forming cavities 2 correspond to six die-casting molds 13, and multiple encoder housing bodies can be produced at one time, greatly improving the working production efficiency; the sealing ring 14 tightly seals the periphery of the upper opening of the forming cavity 2 to prevent the extrusion, splashing and leakage of materials.

[0030] Working principle: When using this precision temperature-controlled encoder body precision casting machine, first, under normal conditions, the sealing plate 5 is located below the inside of the forming cavity 2 under its own gravity and is used as a bottom plate. The material is poured into the inside of the forming cavity 2, and then the hydraulic cylinder 11 is started to push the movable plate 12 downward, so that each die-casting mold 13 is inserted into the corresponding forming cavity 2. After the die-casting mold 13 is inserted into the forming cavity 2, the sealing ring 14 tightly seals the periphery of the upper opening of the forming cavity 2 to prevent the extrusion, splashing and leakage of materials. After waiting for the forming, the hydraulic cylinder 11 pulls up the die-casting mold 13, and then the air pump 6 is used to suck the outside air, which is transported through the air pipe 7 and then ejected through each air nozzle 8. Under the action of the air flow, the sealing plate 5 moves upward, so as to push out the housing and perform rapid demolding work. And with the flow of the air flow, the formed housing can also be cooled. This is the working principle of this precision temperature-controlled encoder body precision casting machine.
