Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding machines, and more specifically, particularly relates to a mold release agent spraying mechanism of an injection molding machine. Background Art

[0002] In order to improve demoulding efficiency and optimize the quality of finished products, modern injection molding processes widely use automatic release agent spraying technology. The principle is to install the release agent bottle at the bottom of the mechanical arm of the injection molding machine, and control the press switch of the release agent bottle by driving the cylinder piston rod. This automated process not only ensures that the release agent can be sprayed evenly and accurately on the inner surface of the mold, but also greatly reduces the labor intensity of workers. The existing release agent spraying mechanism of the injection molding machine is generally composed of a fixing connected to the mechanical arm, a release agent bottle fixed in the placement part, and a driving cylinder that controls the press switch of the release agent bottle.

[0003] Based on the above, the driving cylinder is fixed to one side of the fixing part by bolts, and its design allows for vertical height adjustment to accommodate release agent bottles of different sizes. However, when the specifications of the release agent bottle change, it is necessary to first loosen the fastening bolts, lift it to a suitable height, and then tighten the bolts again. Sometimes, multiple adjustments are required to ensure the pressing effect of the release agent bottle push switch, and the operation is relatively cumbersome. Utility Model Content

However, when the specifications of the release agent bottle change, it is necessary to first loosen the fastening bolts, lift them to a suitable height, and then tighten the bolts again. Sometimes multiple adjustments are required to ensure the pressing effect of the release agent bottle press switch, and the operation is relatively cumbersome.

[0005] The purpose and effect of the mold release agent spraying mechanism of the utility model for an injection molding machine are achieved by the following specific technical means:

[0006] A mold release agent spraying mechanism for an injection molding machine comprises a mechanical arm main body; a mounting member, the mounting member is hingedly connected to the bottom of the mechanical arm main body; a fixing box, the fixing box is fixedly connected to the left side of the mounting member; a fixing member, the fixing member is arranged below the fixing box; a mold release agent bottle, the mold release agent bottle is fixedly connected inside the fixing member; a fixing belt, the fixing belt is provided with two pieces, and the two pieces of the fixing belt are dispersedly fixedly connected to the left side of the fixing member; a fixing block, the fixing block is fixedly connected to the left side of the top of the fixing member; a pressing cylinder, the pressing cylinder is arranged on the left side of the top of the fixing member; a central pressing assembly, the central pressing assembly is arranged on the top of the fixing member; and an installation and disassembly assembly is arranged inside and below the fixing box.

[0007] Furthermore, the central pressing assembly includes: a first lead screw, which is threadedly connected to the inside of the fixed block; and a transverse knob, which is coaxially fixedly connected to the left side of the first lead screw.

[0008] Furthermore, the center pressing assembly also includes: a guide rod, which is slidably connected inside the fixed block; a connecting plate, which is fixedly connected to the left side of the guide rod and is rotatably connected to the left end of the first screw.

[0009] Furthermore, the central pressing assembly also includes: a second lead screw, which is rotatably connected to the inside of the connecting plate; a longitudinal knob, which is coaxially fixedly connected to the top of the second lead screw; a connecting slider, which is slidably connected to the inside of the connecting plate, the connecting slider is threadedly connected to the second lead screw, and the left side of the connecting slider is fixedly connected to the pressing cylinder.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] First of all, by rotating the longitudinal button, the up and down movement adjustment of the pressing cylinder can be easily achieved. This design greatly simplifies the operation process and improves the convenience of use. Rotating the horizontal button allows fine-tuning of the left and right position of the pressing cylinder to ensure that the piston rod and the press switch of the release agent bottle are precisely aligned to form a straight line, thereby ensuring that the pressing cylinder can accurately reach the target position during operation, improving work efficiency and stability.

[0014] Secondly, when it is necessary to inspect or replace the parts on both sides of the fixing part, it is only necessary to move the two sliding plates outward at the same time to disengage the limit plates from the limit grooves, and the fixing part and the fixing box can be easily separated. After the connecting box is inserted into the fixing box, release the sliding plate, and the limit plates will automatically move inward and insert into the limit grooves, firmly fixing the fixing part under the fixing box, simplifying the operation process and improving the efficiency of maintenance work.

[0015] The utility model can easily adjust the position of the pressing cylinder by rotating the longitudinal button and the transverse button. The up, down, left and right adjustments ensure that the piston rod of the pressing cylinder can be accurately aligned with the pressing switch of the release agent bottle. At the same time, the fast disassembly and assembly of the fixing parts and the components on both sides of the fixing parts are realized by installing and disassembling components, which simplifies the inspection process and improves the maintenance efficiency.

[0029] Among them, the central pressing assembly includes: a first lead screw 7, which is threadedly connected to the inside of the fixed block 6; a transverse knob 701, which is coaxially fixedly connected to the left side of the first lead screw 7.
