Description

Technical Field

[0001] The utility model relates to the technical field of a core-mold separation device after a composite material product is solidified, in particular to a step-by-step demoulding device. Background Art

[0002] Pull-out demoulding is a common process for separating the core mold and the product after winding and curing. It is generally done by a horizontally placed hydraulic cylinder. For core molds with large demoulding force and long length, a large-bore long-stroke cylinder must be used. Long-stroke cylinders are more expensive, and the pull rod is prone to bending when extended horizontally, which reduces the service life.

[0003] Therefore, in order to reduce costs, ensure that there is no bending, and increase the service life, a step-by-step demoulding device is proposed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a step-by-step demoulding device, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solutions: a step-by-step demoulding device, comprising a load-bearing frame and a mold placed at the front end of the load-bearing frame, at least four groups of reinforcement plates are arranged on both sides of the load-bearing frame, and a groove is opened at the rear end of the reinforcement plate;

[0006] A demoulding structure capable of achieving distributed demoulding is installed on the inner side of the load-bearing frame, and the demoulding structure is connected to the mold;

[0007] Its demoulding structure and reinforcement plate are connected.

[0008] Through the above technical solution, further, the demoulding structure includes a cylinder seat, and cylinder seat rollers are symmetrically installed on both sides of the cylinder seat and contact the surface of the bearing frame;

[0009] A fixing plate is symmetrically mounted on the front end surface of the oil cylinder seat, and a distribution stop pin which is engaged with the reinforcing plate is arranged inside the fixing plate.

[0010] Furthermore, the demoulding structure also includes an oil cylinder installed in the oil cylinder seat, and an oil cylinder pull rod is provided at the telescopic end of the oil cylinder, and a connecting plate is connected to the top of the oil cylinder pull rod;

[0011] Connecting plate rollers distributed in a triangle are installed on both sides of the connecting plate, a fixing plate is symmetrically installed on the front side of the front end of the connecting plate, a connecting stop pin is arranged in the fixing plate, and a core mold groove is opened at the left end of the connecting plate.

[0012] As a preferred technical solution, the mold includes a core mold clamped in the connecting plate, and the surface of the core mold is the product.

[0013] Furthermore, the distribution stop pin and the connection stop pin can both be stuck in the groove.

[0014] As a preferred technical solution, the demoulding structure moves along the inner side of the load-bearing frame.

[0015] Compared with the prior art, the utility model provides a step-by-step demoulding device, which has the following beneficial effects:

[0016] 1. This device refers to Figure 1-3 It can be seen that using a shorter hydraulic cylinder to pull out the long core mold in multiple times is particularly suitable for molds with a large pulling force throughout the entire stroke. This method not only reduces the manufacturing cost, but also solves the problem of using a large-bore and long-stroke cylinder, which causes the pull rod to bend easily when extended horizontally, thereby reducing its service life.

DETAILED DESCRIPTION

[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] Example

[0025] See also Figure 1-4The utility model provides the following technical solutions: a step-by-step demoulding device, comprising a bearing frame 1 and a mold placed at the front end of the bearing frame 1, at least four groups of reinforcing plates 2 are arranged on both sides of the bearing frame 1, and a groove is opened at the rear end of the reinforcing plate 2;

[0026] A demoulding structure capable of achieving distributed demoulding is installed on the inner side of the load-bearing frame 1, and the demoulding structure is connected to the mold;

[0027] Among them, the demoulding structure and the reinforcement plate 2 are locked.

[0028] In this implementation, how the distribution is achieved can be found in Figure 1-3 It can be seen that first, the demolding structure moves downward to another group of reinforcement plates 2 in sequence through the reinforcement plate 2 located on the upper side of the load-bearing frame 1 for one demolding, until the bottom of the demolding structure is stuck at the reinforcement plate 2 located at the lower side of the load-bearing frame 1 for the third demolding. Through the step-by-step demolding method, it is possible to use a shorter hydraulic cylinder to pull out the long core mold in multiple times, which is particularly suitable for molds with a large pulling force throughout the entire stroke.

[0029] See also Figure 1 and Figure 2 It can be seen that the demoulding structure includes a cylinder seat 4, and cylinder seat rollers 5 are symmetrically installed on both sides of the cylinder seat 4 and are in contact with the surface of the bearing frame 1;

[0030] A fixing plate 6 is symmetrically mounted on the front end surface of the oil cylinder seat 4 , and a distribution stop pin 7 for engaging with the reinforcing plate 2 is arranged inside the fixing plate 6 .

[0031] In combination with the above, the demoulding structure further includes an oil cylinder 3 installed in the oil cylinder seat 4, and an oil cylinder tie rod 11 is provided at the telescopic end of the oil cylinder 3, and a connecting plate 8 is connected to the top of the oil cylinder tie rod 11;

[0032] Connecting plate rollers 12 distributed in a triangle are installed on both sides of the connecting plate 8, and a fixed plate 6 is symmetrically installed on the front side of the front end of the connecting plate 8. A connecting stop pin 13 is arranged in the fixed plate 6, and a core mold groove 14 is opened at the left end of the connecting plate 8. The demoulding structure also includes an oil cylinder 3 installed in the oil cylinder seat 4, and the telescopic end of the oil cylinder 3 is connected to the connecting plate 8. In the initial state, the oil cylinder 3 moves downward through telescoping. At this time, when the stop pin 7 is located behind the second group of reinforcement plates 2, the stop pin 7 extends out and is stuck in the groove. At this time, the oil cylinder 3 contracts, so that it drives the connecting plate 8 to move downward, and then drives the core mold 9 to be pulled out from the product 10. This is the first demoulding. The above operation is repeated subsequently to remove the core mold 9 from the product 10 in three steps.

[0033] See also Figure 1 It can be seen that the mold includes a core mold 9 clamped in the connecting plate 8, and the surface of the core mold 9 is a product 10.

[0034] See also Figure 4It can be seen that both the distribution stop pin 7 and the connection stop pin 13 can be stuck in the groove.

[0035] The demoulding structure moves along the inner side of the load-bearing frame 1 .

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
