Description

Technical Field

[0001] The utility model relates to the technical field of mold demoulding, in particular to a mold inner cavity spraying device. Background Art

[0002] At present, in the industry, when demoulding during the process of producing parts through molds, it is necessary to spray the mold with a release agent to facilitate demoulding. When spraying the release agent, a manually operated spraying equipment is usually used to directly spray the mold cavity.

[0003] However, when spraying the release agent, the existing spraying equipment only atomizes the release agent and sprays it into the inner cavity of the mold through the nozzle of the spraying equipment. The uniformity of the spraying is not high, and when too much release agent is sprayed, it will slide down along the inner cavity of the mold, occupying the casting space of the cast product, which can easily lead to defects in the appearance of the cast product and also lead to waste of release agent. Utility Model Content

[0004] The purpose of the utility model is to provide a mold inner cavity spraying device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A mold cavity spraying device, comprising:

[0007] A fixed table, with a cylinder fixedly mounted on the upper end of the fixed table, and a mold movably placed on the surface of the fixed table;

[0008] A spraying assembly is fixedly mounted on the lower end of the cylinder;

[0009] An adjusting component is fixedly installed below the spraying component;

[0010] The smearing assembly is fixedly installed below the adjusting assembly. The smearing assembly includes an adsorption strip. A plurality of elastic metal strips are fixedly installed at equal angles inside the adsorption strip. A plurality of pull ropes are fixedly connected at equal angles to the inner surface of the adsorption strip.

[0011] Further, the spraying assembly includes:

[0012] A No. 1 fixing bracket, fixedly mounted on the lower end of the cylinder;

[0013] A second fixing frame, fixedly mounted on the lower surface of the first fixing frame;

[0014] A limiting ring, fixedly mounted on the lower surface of the second fixing bracket;

[0015] A connecting pipe, rotatably connected to the interior of the limiting ring;

[0016] The annular tube is fixedly connected to the connecting tube.

[0017] Preferably: a plurality of nozzles are fixedly connected at equal intervals on the outer surface of the annular tube, a water tank is fixedly installed inside the No. 1 fixing frame, a water pump fixedly connected to the water tank is fixedly installed inside the No. 2 fixing frame, one end of the water pump is fixedly connected to a rotary joint, and one end of the rotary joint is fixedly connected to the connecting pipe.

[0018] Preferably, the adjustment component includes:

[0019] A gear ring, fixedly mounted on the inner surface of the annular tube;

[0020] A connecting ring, fixedly mounted on the outer surface of the annular tube;

[0021] a sleeve ring, rotatably connected to the inner surface of the connecting ring;

[0022] The mounting plate is fixed to the lower surface of the collar through a support rod.

[0023] Preferably: a No. 1 motor is fixedly mounted on the inner surface of the collar, a gear meshing with the gear ring is fixedly mounted on the output end of the No. 1 motor, and a plurality of slide rails are fixedly mounted at equal angles on the outer surface of the mounting plate.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. When the water pump is running and the connecting pipe and the annular pipe are rotated through the connection of the rotary joint, the release agent inside the water tank can still be transported to the inside of the annular pipe. When the No. 1 motor is running, the annular pipe and the nozzle are rotated, and the release agent is sprayed toward the inner cavity of the mold, so that the release agent is sprayed more evenly.

When the adsorption strip moves to the bottom of the mold cavity, the No. 2 motor runs, driving the reel to rotate, so that multiple pull ropes are reeled on the surface of the reel, pulling the adsorption strip to bend and deform toward the middle, so that the adsorption strip fits the bottom of the mold cavity and applies it to the bottom. After the release agent is atomized and sprayed into the mold cavity through the nozzle, the release agent is applied from the top of the cavity to the bottom through the coating component, and the excess release agent is absorbed by the adsorption strip to improve the uniformity of the release agent spraying, so as to avoid occupying the casting space of the cast product when too much release agent is sprayed, improve the appearance integrity of the cast product, and also reduce the waste of release agent.

[0038] Example 1

[0039] like Figure 2 and Figure 4 As shown, in this embodiment, the spraying assembly 2 includes: a No. 1 fixing frame 201 fixedly installed at the lower end of the cylinder 102, a No. 2 fixing frame 202 fixedly installed on the lower surface of the No. 1 fixing frame 201, a limiting ring 203 fixedly installed on the lower surface of the No. 2 fixing frame 202, a connecting pipe 204 rotatably connected to the inside of the limiting ring 203, and an annular pipe 205 fixedly connected to the connecting pipe 204; a plurality of nozzles 206 are fixedly connected at equal intervals on the outer surface of the annular pipe 205, a water tank 207 is fixedly installed inside the No. 1 fixing frame 201, a water pump 208 fixedly connected to the water tank 207 is fixedly installed inside the No. 2 fixing frame 202, one end of the water pump 208 is fixedly connected to a rotary joint 209, and one end of the rotary joint 209 is fixedly connected to the connecting pipe 204.
