Description

Technical Field

[0001] The utility model relates to the technical field of compression molding equipment, in particular to a compression molding mechanism for producing rubber sealing parts. Background Art

[0002] In the production process of rubber products, compression molding is a crucial process step. However, after compression molding, some rubber residues often stick to the mold plate of the existing rubber compression molding machine. These residues not only affect the reuse of the mold, but also may have a potential impact on product quality. In order to remove these adhered rubbers, the current main method is to manually remove them using a high-pressure air gun.

[0003] However, this manual removal method has significant disadvantages. First, the efficiency is extremely low. Workers need to spend time and energy to find and remove the sticking rubber on the formwork, which not only increases production costs but also reduces production efficiency.

[0004] Therefore, in order to improve the production efficiency and product quality of the rubber molding machine and reduce the disadvantages of manual removal, it is necessary to develop a new type of rubber molding machine that can efficiently remove the sticky rubber on the template. Utility Model Content

[0009] A chain, wherein the chain is installed inside the slide slot, and the top and bottom ends of the chain are clamped by the slide slot;

[0010] An air pump, wherein the air pump is a dual-channel air pump, and its air outlet pipes are respectively located at the upper and lower ends of the air pump, and hollow covers are installed on the air outlet pipes. The upper and lower parts of the hollow covers clamp the limit frames, and inclined guide holes are opened on the hollow covers to guide the flow direction of the high-pressure gas generated by the air pump, and a fixing rod is connected between one of the axis bodies of the chain and the air pump.

[0011] As an improvement, a motor is installed on the handheld part, a sprocket is installed on the motor drive shaft, and the sprocket is meshed with the chain.

[0012] As an improvement, the guide hole is in the shape of an inclined quadrilateral.

[0013] As an improvement, rollers are installed at both upper and lower ends of the chain, and there are a plurality of rollers that fit in the slide grooves.

[0015] As an improvement, a support plate 1 is fixed on the template mounting frame on the molding machine body, and a support plate 2 is installed on the limiting frame.

[0016] The utility model has at least the following beneficial effects: after the production of the rubber seal is completed, as the main body of the molding machine separates the upper and lower templates by a certain distance, the staff can directly insert the limit frame into the middle of the template, and under the action of the chain and the guide holes on the hollow cover, the air pump rotates around the template, and the high-pressure gas it generates always flows from the edge of the template to the middle of the template, while removing the adhesive glue on the template, the direct contact between the seal and the template is loosened, which is convenient for the subsequent demolding of the seal.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a compression molding mechanism for producing rubber seals, comprising a compression molding machine body 1, and also comprising:

[0025] A placing rack 2, the placing rack 2 is fixed on the molding machine body 1;

[0026] The limiting frame 3 is located in the placement frame 2, a slide groove 31 is provided on the inner wall of the limiting frame 3, and a hand-held portion 32 is provided on the limiting frame 3;

[0027] The chain 4 is installed in the slide slot 31, and the top and bottom ends of the chain 4 are clamped by the slide slot 31;

[0028] The air pump 5 is a dual-channel air pump, and its air outlet pipe is respectively located at the upper end and the lower end of the air pump 5, and a hollow cover 51 is installed on the air outlet pipe. The upper and lower parts of the hollow cover 51 clamp the limit frame 3. The hollow cover 51 is provided with an inclined guide hole 52. The guide hole 52 guides the flow direction of the high-pressure gas generated by the air pump 5, and a fixing rod 53 is connected between one of the shafts of the chain 4 and the air pump 5.

[0029] A motor 6 is installed on the handheld part 32 , a sprocket 61 is installed on the driving shaft of the motor 6 , and the sprocket 61 is meshed with the chain 4 .

[0030] The guide hole 52 has an inclined quadrilateral shape.

[0031] The high-pressure airflow removes the adhesive glue on the template and loosens the contact between the seal and the template, reducing the difficulty of subsequent demoulding.

[0032] Rollers 41 are installed at both upper and lower ends of the chain 4 , and there are a plurality of rollers 41 , which fit in the slide grooves 31 .

[0033] The friction between the chain 4 and the slide groove 31 is reduced, and the service life is prolonged.

[0034] The limiting frame 3 and the hand-held portion 32 are both made of hard plastic.

[0035] The force required for workers to hold the device is reduced, thereby reducing the labor intensity of workers.

[0036] A support plate 1 71 is fixed on the template mounting frame on the molding machine body 1 , and a support plate 2 72 is installed on the limiting frame 3 .

[0037] The cooperation between the support plate 1 71 and the support plate 2 72 enables the worker to not need to use his hands to support the limit frame 3 all the time during the operation. After the two are in contact, the motor 6 can be turned on and off by the switch of the handheld part 32, which saves time and effort.

[0038] The working principle of the utility model is as follows: after the molding machine body 1 forms the seal, as the molding machine body 1 separates the upper and lower templates for a distance, the staff can directly insert the limit frame 3 into the middle of the template to make the support plate 1 71 and the support plate 2 72 contact. At this time, the switch of the handheld part 32 is turned on, and the motor 6 drives the chain 4 to rotate through the sprocket 61, and the chain 4 drives the air pump 5 to move synchronously. At the same time, the air pump 5 generates a high-pressure airflow. Under the action of the guide hole 52, the high-pressure gas is always sprayed from the edge of the template to the middle of the template. While removing the adhesive glue on the template, the contact between the seal and the template is loosened, thereby reducing the difficulty of subsequent demolding.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
