Description

Technical Field

[0001] The utility model relates to the technical field of pouring machines, in particular to a foaming pouring machine for an automobile buffer block. Background Art

[0002] Polyurethane is a new type of material produced by the polycondensation of liquid isocyanate and polyether diol. Compared with ordinary rubber, it has higher mechanical strength, oxidation stability, and excellent oil resistance, solvent resistance, water resistance, and fire resistance. Buffer blocks are important components of automobile suspension shock absorption systems. Many companies use polyurethane to replace ordinary rubber as the preparation material for buffer blocks.

[0003] A common preparation method for polyurethane buffer blocks is to adopt a foaming process, mixing the raw materials of polyurethane in a mixing head and then injecting them into a mold through a pouring tube. For some casting machines that are equipped with multiple foaming molds, the molds need to be poured one by one. During the process of transferring the pouring tube, the residual foaming liquid in the pouring tube is easy to drip around the device. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a foaming pouring machine for an automobile buffer block. During the use of the pouring machine, a one-way sealing mechanism is used to effectively prevent the residual foaming liquid from easily dripping around the device. In addition, by using a limiting mechanism, the pouring pipe can be conveniently limited at the injection port of the foaming mold, without the need for the user to hold the pouring pipe all the time.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A foaming pouring machine for an automobile buffer block comprises a mixing box; a pouring mechanism, wherein the pouring mechanism comprises a pump body installed on the left side of the mixing box, the liquid inlet end of the pump body extends to the inner bottom of the mixing box, the liquid outlet end of the pump body is connected to a hose, and the other end of the hose is connected to a cannula; a one-way sealing mechanism, wherein the one-way sealing mechanism is used to prevent liquid backflow in the cannula; and a limiting mechanism, wherein the limiting mechanism is used to limit the cannula.

[0007] Preferably, a feeding port is provided at the upper end of the mixing box.

[0008] Preferably, a support seat is installed at the lower end of the mixing box.

[0009] Preferably, the one-way sealing mechanism includes a sealing plate arranged at the lower end of the insert tube, and two slide grooves are symmetrically opened at the lower end of the insert tube, and each of the slide grooves is provided with a slide bar that can slide up and down, and the upper ends of the two slide bars are elastically connected to the inner top of the corresponding slide groove through a second spring, and the lower ends of the two slide bars are fixedly connected to the sealing plate.

[0010] Preferably, the limiting mechanism comprises two support plates respectively arranged on both sides of the insertion tube, and opposite sides of the two support plates are elastically connected to both sides of the insertion tube through a first spring.

[0011] Preferably, rectangular guide rods are fixedly connected to both sides of the insertion tube, and the two rectangular guide rods both penetrate the support plate and are slidably connected to the support plate.

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

[0013] A limiting mechanism is provided. Through the use of the limiting mechanism, the insert tube is limited at the injection port during pouring work, and the staff does not need to hold the insert tube all the time, which facilitates the staff's operation. In addition, through the use of the one-way sealing mechanism, during the injection process, due to the high pressure in the pipeline, the lower end face of the insert tube is conductive. After the injection is completed, the sealing plate moves up to seal the lower end face of the insert tube, which can avoid the material dripping when the insert tube is moved subsequently.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A foaming pouring machine for automobile buffer blocks includes a mixing box 2, a feeding port 5 is provided at the upper end of the mixing box 2, a support seat 1 is installed at the lower end of the mixing box 2, and the mixing box 2 is a prior art, which is provided with a matching stirring and mixing structure, such as a motor and a stirring rod, which can achieve a better mixing effect;

[0020] The pouring mechanism also includes a pump body 3 installed on the left side of the mixing box 2, the liquid inlet end of the pump body 3 extends to the inner bottom of the mixing box 2, the liquid outlet end of the pump body 3 is connected to a hose, and the other end of the hose is connected to a cannula 4;

[0021] Among them, it also includes a one-way sealing mechanism, which is used to prevent the liquid in the cannula 4 from flowing back. The one-way sealing mechanism includes a sealing plate 9 arranged at the lower end of the cannula 4. The lower end of the cannula 4 is symmetrically provided with two slide grooves 10. Each slide groove 10 is provided with a slide bar 12 that can slide up and down. The upper ends of the two slide bars 12 are elastically connected to the inner top of the corresponding slide groove 10 through a second spring 11, and the lower ends of the two slide bars 12 are fixedly connected to the sealing plate 9.

[0022] It also includes a limiting mechanism, which is used to limit the insertion tube 4. The limiting mechanism includes two support plates 6 respectively arranged on both sides of the insertion tube 4. The opposite sides of the support plates 6 are arc-shaped and are provided with a rubber layer. The opposite sides of the two support plates 6 are elastically connected to the two sides of the insertion tube 4 through the first spring 8. Rectangular guide rods 7 are fixedly connected to both sides of the insertion tube 4. The two rectangular guide rods 7 pass through the support plates 6 and are slidably connected to the support plates 6.

[0023] In the utility model, before pouring, the materials are put into the feeding port 5, enter the mixing box 2, and are mixed by the mixing structure of the mixing box 2;

[0024] When pouring is required, just press the two support plates 6 first, make the two support plates 6 move relative to each other, insert them into the injection port of the foaming mold, loosen the two support plates 6, and under the elastic action of the two first springs 8, the two support plates 6 are tightly fitted to the inner wall of the injection port, and the friction force is used to complete the limit;
