Description
Technical Field
[0001] The utility model relates to the field of injection mold related equipment, in particular to a quick connection device for an injection machine for rubber oil seals. Background Art
[0002] At present, injection technology is more and more popular in the manufacturing industry. There are various devices such as injection molds, templates, and runners developed accordingly. However, at present, the templates, upper heating plates, and runners have always been connected in a traditional bolt-tightening manner, which causes some waste of time. Moreover, the bolt connection method is relatively troublesome and requires repeated confirmation of the connection degree of the bolts. Injection technology has always been used to produce seals with the advantages of high efficiency and stability. Therefore, whether it is possible to further reduce the production time loss in the entire production process has become an important research direction. Summary of the Invention
[0003] The purpose of the utility model is to provide a quick connection device for an injection machine for rubber oil seals, aiming to solve the problems of cumbersome operation, repeated confirmation of the connection degree, and large time consumption when connecting the template, heating plate, and runner in a traditional bolt-tightening manner.
[0004] The technical solution adopted by the utility model is: a quick connection device for an injection machine for rubber oil seals, including an upper template and a runner. The upper template is docked with the runner. Six vertically installed connecting rods are arranged on the upper template. The connecting rods are distributed on the upper template in a distribution pattern of three rows and two columns. An upper heating plate is arranged above the upper template. The size of the upper heating plate is the same as that of the upper template. Six through holes are arranged on the upper heating plate. The positions of the through holes correspond to the positions of the connecting rods. The connecting rods pass through the through holes and extend upward. A pair of connecting strip mounting grooves are arranged on the runner. Through holes corresponding to each other are respectively arranged at the upper and lower parts of the connecting strip mounting grooves. A connecting strip is installed in the connecting strip mounting groove. The connecting strip is in a long strip shape. Three connecting rod clamping holes are arranged on the connecting strip. The connecting rod clamping holes include a large round hole and a small round hole. The large round hole and the small round hole are connected so that the cross-section of the clamping hole is in a gourd shape.
[0005] A further technical solution of the utility model is: a retaining pin is arranged at one end of the connecting strip mounting groove, and a retaining pin clamping groove is arranged at one end of the connecting strip. The retaining pin is clamped into the retaining pin clamping groove so that the connecting strip is fixed in the connecting strip mounting groove, which is convenient for disassembly and connection.
[0006] A further technical solution of the utility model is: a conical clamping block is arranged on the head of the connecting rod to improve the connection stability.
[0007] A further technical solution of the utility model is: the retaining pin is installed on the end of the connecting strip through a hinge for convenient operation.
[0008] The beneficial effects of the present utility model are as follows: Due to the adoption of the above technical solution, a quick connection device for an injection machine for rubber oil seals of the present utility model can quickly and efficiently connect the upper template, the heating plate and the runner, with high connection efficiency and stable connection performance, effectively reducing the time loss in production and improving production efficiency.

[0013] The following further describes the present utility model in conjunction with the drawings and specific embodiments.
[0014] Embodiment:
[0015] As Figures 1 to 4 shown, a quick connection device for an injection machine for rubber oil seals includes an upper template 1 and a runner 2. When in use, the upper template is docked with the runner 2. Six vertically installed connecting rods 3 are provided on the upper template 1. The connecting rods are distributed on the upper template in a distribution pattern of three rows and two columns. An upper heating plate 4 is provided above the upper template 1. The size of the upper heating plate 4 is the same as that of the upper template 1. Six through holes are provided on the upper heating plate. The positions of the through holes correspond to the positions of the connecting rods. The connecting rods pass through the through holes and extend upward. A pair of connecting strip installation grooves 5 are provided on the runner 2. Through holes corresponding to each other are respectively provided in the upper and lower parts of the connecting strip installation grooves. A connecting strip 6 is installed in the connecting strip installation grooves. The connecting strip is strip-shaped. Three connecting rod clamping holes are provided on the connecting strip. The connecting rod clamping holes include a large round hole 61 and a small round hole 62. The large round hole and the small round hole are connected so that the cross-section of the clamping hole is in a gourd shape. When the connecting strip is installed in the connecting strip installation groove, first make the large round hole correspond to the through hole, and then dock the upper template with the runner. After the connecting rods on the upper template are inserted into the through holes on the runner and pass through the large round holes, push the connecting strip further. At this time, the small round hole will be sleeved on the connecting rod.
[0016] Furthermore, a retaining pin 7 is provided at one end of the connecting strip installation groove, and a retaining pin slot 63 is provided at one end of the connecting strip. The retaining pin is inserted into the retaining pin slot to fix the connecting strip in the connecting strip installation groove, facilitating the locking of the connecting strip.
[0017] Furthermore, a conical clamping block 31 is provided on the head of the connecting rod to enhance the connection stability.
[0018] Furthermore, the clamping pin is installed on the end of the connecting strip through a hinge member for easy operation and use.
[0019] During use, 6 protruding connecting rods (3 rows × 2 columns) are designed on the upper template, which will pass through the upper heating plate and be inserted into the runner. Similarly, 6 corresponding through holes (3 rows × 2 columns) are designed on the runner. Two channels (i.e., connecting strip installation grooves) passing through the through holes are designed in the horizontal direction of the runner, aiming to place a connecting strip that can be pulled and locked therein. By pulling out and inserting the connecting strip, the separation and connection of the upper template and the runner are achieved.
[0020] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
